VW, BMW and ChargePoint partner to create SAE Combo DC fast charging corridors on the East and West Coasts
In a major boost to the availability of public fast charging stations with SAE Combo connectors (J1772, earlier post), Volkswagen of America and BMW of North America, together with ChargePoint, the largest electric vehicle charging network, announced at the Washington Auto Show an initiative to create more express charging corridors along heavily-traveled routes on the East and West Coasts.
In the initial phase, the aim is to install nearly 100 DC Fast charging ports across both coasts, with plans to expand the program to increase access to fast charging across the country. The installations will occur both within and between relevant metro areas, strategically spaced at a maximum of 50 miles (80 km) apart. Each fast charging location along the express charging corridors is expected to include up to two 50 kW DC fast chargers or 24 kW DC fast chargers with the SAE Combo connector. The 50 kW fast chargers will also have a CHAdeMO connector available, according to Volkswagen, while the 24 kW units will be SAE Combo only, at least to start.
UQM Technologies granted patent on permanent magnet electric motor design using non-rare earth magnets
January 20, 2015
UQM Technologies Inc. has been granted a US patent (8,928,198, “Brushless PM machine construction enabling low coercivity magnets”) for an electric and hybrid electric vehicle motor design using non-rare earth magnets. The patent covers the unique magnet geometry and the method of manufacturing the motor.
The majority of electric and hybrid electric vehicles produced today use permanent magnet (PM) motors with rare-earth magnet materials because of the high coercivity of the rare earth materials. Coercivity is a measure of the reverse field needed to drive magnetization to zero after being saturated—i.e., it is a measure of the resistance to demagnetization. The new UQM design enables the use of low coercivity magnets, such as Aluminum Nickel Cobalt (AlNiCo) or Iron Cobalt Tungsten (FeCoW), in PM machines.

Tesla to begin piloting battery pack swap program for invited Model S owners
December 20, 2014
Starting next week, Tesla Motors will pilot a battery pack swap program with invited Model S owners. The selected owners will have the opportunity to swap their car’s battery at a custom-built facility located across the street from the Tesla Superchargers at Harris Ranch, CA. Tesla intends the pilot program to test the technology and to assess demand.
The Harris Ranch Superchargers sit off the I-5, the interstate highway connecting Los Angeles (and San Diego) with the San Francisco Bay Area and Sacramento in the north. Harris Ranch is roughly equidistant from Sacramento (~187 miles); San Francisco (~183 miles); and LA (~199 miles).
Washington governor proposes slate of measures to curb GHG emissions & transition state to cleaner energy; cap-and-trade and EV incentives
December 17, 2014
Washington Governor Jay Inslee announced a set of proposals to transition Washington to cleaner sources of energy and to meet greenhouse gas (GHG) emission limits adopted by the state Legislature in 2008. The proposals build on a comprehensive executive order issued by the governor in April.
Cap-and-trade. The proposed “Carbon Pollution Accountability Act” (CPAA) would create a new, market-based program that sets an annual limit CO2 emissions; major emitters will need to purchase “allowances” for their emissions. Each year, the number of available allowances will decline to ensure emissions are gradually reduced. The Governor’s office projects that the program will generate about $1 billion in the first year, and more thereafter, which will be used for transportation, education, tax relief for working families and other purposes.

|BMW 3 Series Plug-in hybrid prototype. Click to enlarge.|
BMW has unveiled a 3 Series plug-in hybrid prototype. Combining a four-cylinder TwinPower Turbo gasoline engine from the new Efficient Dynamics engine family with an electric motor, the BMW 3 Series plug-in hybrid prototype offers performance on a par with a conventionally powered BMW 3 Series six-cylinder model, combined with a significant reduction in fuel consumption.
In addition, BMW outlined its work on Power eDrive next-generation electrification platforms—an effort to deliver “highly electrified” plug-in hybrids with higher-powered electric motors and batteries with twice the capacity of present versions. Future plug-in hybrid concepts, said BMW, will use the electric motor—the main source of power for everyday driving—to drive the rear wheels, while a second electric motor driving the front wheels will create an all-electric road-coupled all-wheel-drive system. At the same time, an internal combustion engine will also supply power to the front axle.
Renault-Nissan Alliance has sold 200,000 EVs worldwide so far; 58% ZEV market share
November 26, 2014
The Renault-Nissan Alliance has passed the 200,000th electric vehicles sold mark and currently has a leading 58% market share for zero-emission cars (ZEVs) worldwide. Together, Renault and Nissan EVs have driven approximately 4 billion zero-emission kilometers (2.5 billion miles)—enough to circle the earth 100,000 times. Alliance EVs also represent 450 million kg of CO2 that has not been emitted while driving. (The zero-emission distance and CO2 data are based on a calculated average.)
Of those EVs, Japan-based Nissan has sold a cumulative 148,700 units worldwide since December 2010, when Nissan LEAF went on sale. The top markets for Nissan LEAF are the United States with about 67,000 sales since its launch; Japan with about 46,500 units; and Europe with about 31,000 units.
Lux Research: fuel cell vehicles lag other drivetrains in terms of cost of ownership; ICE and HEV lowest cost
November 24, 2014
Based on an analysis of various cost of ownership scenarios for various drivetrains, including internal combustion engine (ICE) gasoline and diesel; hybrid (HEV); battery-electric (EV); plug-in hybrid electric (PHEV); and fuel cell vehicles, Lux Research concludes that fuel cell vehicles (FCVs) are “solidly in a laggard position.”
The Lux analysts ran scenarios associated with operation and ownership, broken out into fuel cost alone; fuel cost plus operation, but excluding purchase or lease; and fuel cost plus operation, including purchase or lease (total ownership cost). When looking at fuel cost only, EVs lead the way due to the relatively low price of electricity, followed by various types of hybrids (HEVs and PHEVs). Fuel cell vehicles can match EV fuel costs at $3/kg dispensed H2—a price highly unlikely in near-term, Lux said.
DOE to fund development of processes to aggregate purchases of alt-fuel and advanced vehicles; goal is cost reduction and accelerated adoption
November 21, 2014
DOE plans (DE-FOA-0001236) to issue in the February 2015 timeframe a funding opportunity (DE-FOA-0001237) to develop and to implement effective purchasing/procurement processes designed to coordinate and consolidate bulk alternative fuel vehicle and advanced vehicle orders and thus reduce the per-unit prices of commercially-available vehicles.
DOE expects that such an aggregated purchasing/procurement process will enable original equipment manufacturers (OEMs) and suppliers to increase production volumes; achieve economies of scale; and reduce incremental vehicle costs specific to electric drive, natural gas, propane, hybrid, and other alternative fuel vehicle and advanced vehicle technologies.

In 2023, Navigant expects China to have 85% of the total market.
This growth in demand is expected to result in revenue for global e-bicycle sales of $13.5 billion by 2023. Under Navigant Research’s aggressive scenario, in which e-bicycle become a stronger alternative to passenger vehicles in urban environments, global e-bicycle sales could reach as many as 44.4 million units annually by 2023.
ICCT study finds state EV incentives playing a significant role in driving sales
October 31, 2014
A study by a team from the International Council on Clean Transportation (ICCT) shows that state electric vehicle incentives are playing a significant early role in reducing the effective cost of ownership and driving electric vehicle sales.
As described in their white paper, “Evaluation of state-level US electric vehicle incentives”, the researchers found that some of the states with the largest electric vehicle incentives—i.e., California, Georgia, Hawaii, Oregon, and Washington—have electric vehicle sales shares that are approximately 2–4 times the national average. A statistical regression revealed that the total monetary benefit to consumers from state incentives significantly positively correlates with BEV sales when all 50 states and the District of Columbia are included.

First look at all-new Voltec propulsion system for 2G Volt; “the only thing in common is a shipping cap”
October 29, 2014
The second-generation Volt, which makes its world debut in about 10 weeks at the North American International Auto Show in Detroit, features a clean-sheet, all-new Voltec propulsion system—new battery, new electric drive unit, new power electronics and new range-extending engine. At an introductory media briefing on the new powertrain held at the Warren Transmission Plant in Michigan, where the new drive unit will be built, Larry Nitz, GM Executive Director, Transmission and Electrification, noted that the only common part between the gen 1 and gen 2 drive units was a little yellow plastic intra-plant shipping cap for the manual selector.
The battery cells, with a tweaked NMC/LMO chemistry from LG, increase storage capacity by 20% volumetrically when compared to the original cell. The drive unit features a large number of changes: new roles for the two motors, two clutches instead of three, and a smaller power electronics unit integrated into the housing among them. (No more big orange high-voltage cables underneath the hood.) The new direct-injected 1.5 liter engine with cooled EGR features a high compression ratio and is optimized to function in its range extender role.
GM Warren Transmission Plant to build electric drive unit for second-gen Volt; part of $300M investment in Michigan through end of year
October 28, 2014
Later today at the Detroit Economic Club, General Motors CEO Mary Barra will confirm that its Warren Transmission Plant will build the new electric drive unit—the GM Voltec 4ET50 Multi-Mode EDU—for the upcoming second-generation Chevrolet Volt. As a result, most major Volt powertrain components—from the battery cells to the new 1.5-liter range-extending engine—will be made in Michigan, establishing the state as the company’s global engineering center of excellence for vehicle electrification. The new Volt will debut at the North American International Auto Show in Detroit in January 2015.
The drive unit for the first-generation Volt consists of two motors—a 111 kW main traction and 63 kW (at 4800 rpm) generator motor (55 kW generator output)—as well as three clutches and a planetary gear set tucked in the end of the traction motor that improve overall efficiency by reducing the combined rotational speed of the electric motors as needed. (Earlier post.) GM will subsequently be providing details of the second-generation drive unit.

Californians have purchased or leased more than 100,000 ZEVs. The other seven states—Connecticut, Maryland, Massachusetts, New York, Oregon, Rhode Island and Vermont—account for more than 135,000 vehicles.
Navigant Research forecasts plug-ins will be 2.4% of global new vehicle sales by 2023; luxury brands to represent about 50% of that
Navigant Research forecasts that plug-in EVs (which include plug-in hybrids and battery EVs), will represent 2.4% of total worldwide light-duty vehicle sales by 2023, or about 2.5 million units. In its new report, “Global Forecasts for Light Duty Hybrid, Plug-In Hybrid, and Battery Electric Vehicle Sales and Vehicles in Use: 2014-2023”, Navigant notes that luxury brands, which have benefited in recent years from increased interest from the developing markets of Asia Pacific, have committed more strongly to plug-in EV platforms.
Accordingly, Navigant expects this luxury brand push to increase global sales of plug-in EVs significantly in the near term. Navigant expects sales of plug-in EVs from luxury manufacturers, such as Tesla, Mercedes, Audi, and BMW to grow strongly through 2018 before leveling off at around 50% of the plug-in EV market.
CMU/MIT study finds large-scale battery manufacturing will do little to reduce unit costs past a 200-300 MWh annual production level
October 22, 2014
A new techno-economic analysis by researchers at Carnegie Mellon University (CMU) and MIT has found that economies of scale for manufacturing current Li-ion batteries for light-duty EV applications (in this case, prismatic pouch NMC333-G batteries and packs) are reached quickly at around 200-300 MWh annual production. Increased volume beyond that does little to reduce unit costs, except potentially indirectly through factors such as experience, learning, and innovation, they determined.
“That’s comparable to the amount of batteries produced for the Nissan Leaf or the Chevy Volt last year,” said CMU’s Dr. Jeremy Michalek, the corresponding author of a paper on the research published in the Journal of Power Sources. “Past this point, higher volume alone won’t do much to cut cost. Battery cost is the single largest economic barrier for mainstream adoption of electric vehicles, and large factories alone aren’t likely to solve the battery cost problem.”
Daimler restructures cooperation with Tesla; termination of share-price hedging and sale of 4% stake
October 21, 2014
Daimler AG has restructured its cooperation with Tesla Motors. Daimler has terminated the share-price hedge it initiated in 2013 and has sold its stake in Tesla of approximately 4%. The cooperation between the partners on the automotive projects is unaffected. Development work for the Mercedes-Benz B-Class Electric Drive (http://www.greencarcongress.com/2014/10/20141021-bklasse.html) is completed, and the partnership with Tesla remains in place, Daimler said.
Daimler initially acquired a 9.1% interest in Tesla in May 2009. 40% of that investment was transferred to Aabar Investments PJSC in the context of a joint strategic project in July 2009. Tesla has been listed on the stock exchange since the end of June 2010. As a result of capital increases at Tesla, Daimler’s stake in the company decreased to around 4%, without affecting the two companies’ strategic cooperation or joint development projects.
More on the Mercedes-Benz 2014 B-Class alternative drive systems: electric and natural gas
|B-Class Electric Drive (right) and B-Class Natural Gas Drive (left). Click to enlarge.|
Mercedes-Benz earlier gave the already successful B-Class a thorough facelift, giving particular attention to an upgrade of the interior. (Earlier post.) The revamped B-Class offers a choice of five diesel models with fuel ranging from 3.6 to 5.0 l/100 km (65.3 to 47 mpg US) and four gasoline engines at between 5.4 and 6.6 l/100 km (43.6 and 35.6 mpg US) as well as the B-Class Electric Drive (earlier post) and the B 200 Natural Gas Drive.
Both alternative drive models feature the modular “ENERGY SPACE” bodyshell concept: the underbody houses either the lithium-ion battery (B-Class Electric Drive) or one large and two smaller natural gas tanks and a 14‑liter gasoline tank (B 200 Natural Gas Drive). The B-Class Electric Drive and the B-Class Natural Gas Drive also differ in design from the gasoline and diesel models—particularly in the shaping of the front and rear aprons and the side skirts.

|Visio.M EV. Click to enlarge.|
The academic and industry partners in the Visio.M consortium (earlier post) are showcasing their new lightweight urban electric vehicle at eCarTec in Munich. The 2.5-year project was funded under the priority program “Key Technologies for Electric Mobility - STROM” of the German Federal Ministry for Education and Research (BMBF) with a total budget of €10.8 million (US$13.7 million).
The Visio.M has a range of around 160 kilometers (99 miles) and can accommodate two people with luggage. With only a 15 kW motor, the vehicle reaches a maximum speed of 120 km/h (75 mph). The electric motor in Visio.M draws its power from a lithium-ion battery pack behind the seats, which consists of consumer cells and provides a capacity of 13.5 kWh.
California ARB mods to ZEV regulations for IVMs would result in ~1.9% drop in total ZEV/TZEV units 2018-2025; no impact on air quality requirements
Early in September, the California Air Resources Board (ARB) announced it would consider in a 23-24 October meeting amendments to the Zero Emission Vehicle (ZEV) regulation that would modify the requirements for intermediate volume manufacturers (IVMs) selling into the state to allow them more time to come into the market. (Earlier post.)
Among the proposed changes were additional production lead time; a reduced compliance obligation (i.e., lower numbers of ZEVs); an opportunity to pool compliance obligations in ZEV states; and additional time to make up ZEV credit deficits. ARB staff estimated the proposed modifications could reduce total California deliveries of ZEVs (fuel cell and battery-electric vehicles) and TZEVs (Transition Zero Emission Vehicles, i.e., plug-in hybrids) by a total of about 26,000 units in the 2018 through 2025 timeframe out of the originally estimated 1,400,000 ZEVs and TZEVs for that period under the current regulation—i.e., by about 1.9%. (For MY 2026 and following, the reduced compliance obligation goes away.)
Siemens integrates EV motor and inverter in single housing; common cooling and SKiN
October 17, 2014
|Siemens has developed a solution for integrating an electric car's motor and inverter in a single housing. Click to enlarge.|
Siemens has developed a solution for integrating an electric car’s motor and inverter in a single housing. The motor and the inverter, part of the power electronics which converts the battery’s direct current into alternating current for the motor, have up to now been two separate components. The new integrated drive unit saves space, reduces weight, and cuts costs.
The solution’s key feature is the use of a common cooling system for both components. This ensures that the inverter’s power electronics don’t get too hot despite their proximity to the electric motor, and so prevents any reduction in output or service life.

Visio.M researchers develop lightweight torque vectoring transmission for EVs; improved regen, better dynamics
October 15, 2014
|The lightweight torque vectoring transmission is applied in a Visio.M test vehicle. Click to enlarge.|
As part of the Visio.M project in Germany, researchers at the Technische Universität München (TUM), along with their colleagues in the consortium, have developed a lightweight torque vectoring transmission with characteristics that are optimally adapted to electric vehicles. The engineers at the Gear Research Center (FZG) at TUM focused on recouping as much braking energy as possible with the goal of enhancing the range of the vehicle.
Whereas drive torque conventionally is distributed evenly to the wheels of the drive axle, a torque vectoring system allocates torque between the wheels as required, noted FZG engineer Philipp Gwinner. This provides particularly good drive dynamics. As an example, when a vehicle accelerates in a curve, greater torque is applied to the outside wheel. The car steers itself into the curve. The result: greater agility and, at the same time, safer road handling.

The live demonstration will showcase demand response and load curtailment capabilities through a single standards-based interface. The demonstration will involve 8 EV manufacturers, and attendees will include representatives from the state and federal public agencies involved with clean energy and transportation technologies, as well as the utility and automotive industries.
IHS teardown of Tesla Model S finds more commonality with smartphones and tablets than autos in user-facing electronics
An initial report from IHS’ Teardown Analysis Service finds that, in terms of design, components and manufacturing, the Tesla Model S user-oriented subsystems—i.e., the infotainment and instrumentation system—have more in common with a tablet or smartphone than they do with a conventional automobile.
IHS is in the process of conducting a complete teardown of a 2013 Model S acquired at auction, dissecting and analyzing each subsystem, from the air-conditioning controls, to the safety systems, to the powertrain. The initial analysis focuses on the car’s two most electronics-intensive segments: the virtual instrument cluster and the premium media control unit—aka the head unit—which is the main center stack and touch-screen panel.
New Flyer to start development of first 60' fuel cell hybrid bus in North America; introduces 40' battery-electric bus

The electric propulsion system being integrated into New Flyer’s Buy America-compliant Xcelsior X60 heavy-duty transit bus platform includes a combination of batteries, a fuel cell, and hydrogen storage. The electric drive bus will allow the fuel cell to operate at a relative steady-state, while the batteries will be able to both capture breaking energy and provide power for acceleration.
PEV potential pipeline: possible, promised or planned (13 October 2014 edition)
October 13, 2014
The last few weeks have seen a number of statements from executives at major automakers either pre-announcing, indicating possible development of or simply hinting at a number of new plug-in vehicle models coming over the next couple of years. That should be no surprise; the US-based Electric Drive Transportation Association notes that there are 20 plug-in and fuel cell vehicle models currently on the US market alone with 20 additional models expected here through 2016.
Given that sometimes there is not much more information available than one sentence uttered during an interview or a conference, it’s hard to pull together much that is substantive. However, we thought we’d try keeping a running tally of PEVs possible, promised or planned, with regular updates of the list; globally, to the best of our ability. Please add what we might have missed via the comments section; we’ll incorporate those into the next version of the PEV list. (Concept cars or officially announced models don’t count for this purpose.)
EPA annual trends report finds new vehicle fuel economy at record 24.1 mpg; new powertrain technologies rapidly gaining share
October 10, 2014
EPA released the latest edition of its annual report on trends in CO2 emissions, fuel economy and powertrain technology for new personal vehicles in the US. Among the top-level findings was that Model year 2013 vehicles achieved an average of 24.1 mpg (9.76 l/100 km)—a 0.5 mpg increase over the previous year and an increase of nearly 5 mpg since 2004. Fuel economy has now increased in eight of the last nine years; average carbon dioxide emissions are also at a record low of 369 g/mile in model year 2013. The majority of the carbon and oil savings from current vehicles is due to new gasoline vehicle technologies, the report observed.
The report, “Light-Duty Automotive Technology, Carbon Dioxide Emissions, and Fuel Economy Trends: 1975 Through 2014”, also found that the light truck market share increased slightly in MY 2013, after several years of volatility; that the vehicle weight trend is flat and vehicle power trend is increasing more slowly; that many new powertrain technologies are rapidly gaining market share; and that consumers have an increasing number of high fuel economy/low CO2 vehicle choices.

New “2-in-1” EV unit integrates traction motor and A/C compressor for increased range in hot climates
October 01, 2014
Engineers from Nanyang Technological University (NTU) and the German Aerospace Centre (DLR) have designed a “2-in-1” electric motor unit which can increase the range of electric vehicles in hot climates. This innovative electric machine integrates the A/C compressor, the compressor drive motor and the traction motor into a single housing physically clutching with the compressor during braking events.
The approach unifies the EV traction and compressor drives into a single housing which drive together during braking events. Based on simulations and analysis, the team expects the system to reduce battery consumption by at least 3% compared to existing mechanisms while improving the regenerative energy capturing capacity of the system by 8%. Overall, the novel design could increase the range of electric vehicles by an additional 15 to 20% with other modifications, the researchers suggested.
ORNL study finds best current use of natural gas for cars is efficient production of electricity for EVs
September 24, 2014
|Top: Components of well-to-wheels pathway. Middle: WTW efficiency for CNGVs. Bottom: WTW efficiency for EVs. Curran et al. Click to enlarge.|
A well-to-wheels analysis of the use of natural gas for passenger vehicles by a team of researchers from Oak Ridge National Laboratory (ORNL) has found that, with a high PTW (pump-to-wheels) efficiency and the potential for high electrical generation efficiency with NGCC (natural gas combined cycle) turbines, natural gas currently is best used in an efficient stationary power application for charging EVs.
However, they also noted, high PTW efficiencies and the moderate fuel economies of current compressed natural gas vehicles (CNGVs) make them a viable option as well. If CNG were to be eventually used in hybrids, the advantage of the electric generation/EV option shrinks. Their open access paper is published in the journal Energy.
California governor signs 6 bills to advance state’s electric vehicle market; HOT and HOV benefits
September 22, 2014
Capping off National Drive Electric Week, California Governor Jerry Brown signed into law half a dozen bills to strengthen California’s best-in-the-nation electric vehicle market, including free or reduced-rate access to new high-occupancy toll (HOT) lanes, and more HOV stickers for plug-in hybrids.
The action builds on the state’s efforts to support the growth of the electric vehicle market, including legislation Governor Brown signed last year and the executive order he issued in 2012 to establish a target of 1.5 million zero-emission vehicles on the road in California by 2025 and a number of other long-term goals. California accounts for 40% of US plug-in electric vehicle sales and earlier this month, surpassed 100,000 plug-in electric vehicles sold. (Earlier post.)

DENZA, the “made in China, for China” electric vehicle from Daimler’s technology joint venture with its Chinese partner BYD (earlier post), has started rolling off production line at Shenzhen BYD Daimler New Technology Co., Ltd. (BDNT), in Shenzhen. The joint-venture company, established in 2010 by Daimler and BYD with a 600-million-yuan ($98 million) initial investment, is the first Sino-German joint venture dedicated to an all-electric vehicle in and for China.
DENZA is powered by an 86 kW (peak) / 69 kW (rated) motor that provides a maximum speed of up to 150 km/h (93 mph) and peak torque of 290 N·m (177 N·m rated torque). With a 47.5 kWh lithium iron phosphate battery pack, range is 253 km on the China cycle (157 miles). Energy consumption on the China cycle is 17.2 kWh/100 km (18.9 kWh/100 km with charging losses). Acceleration from 0 – 50 km/h (31 mph) takes 4.5s; acceleration from 50 – 80 km/h (50 mph) takes 5s; and acceleration from 0 – 100 km/h takes 14s.
Renault and Bolloré form a partnership in electric vehicles; assembly, car-sharing and 3-seat Bluecar
Following the letter of intent signed in September 2013 (earlier post), French groups Renault and Bolloré are joining forces to promote electric vehicles through a set of three agreements involving assembly, a car-sharing JV, and new vehicle development. In order to reduce significantly the environmental impact of cars, the partners noted, the development of electric vehicles and car-sharing is not an option—it is a necessary transformation.
The overall environmental impact of an electric vehicle is virtually half that of an equivalent internal combustion engine (ICE) vehicle, Renault noted, citing its comparative study of Fluence ICE and electric vehicles. (Earlier post.) The three agreements include:
UC Riverside team shows new eco-routing navigation tool can cut EV energy use up to 51%
Researchers at the University of California, Riverside’s Bourns College of Engineering have shown that a vehicle navigation tool they created can cut electric vehicle energy use up to 51%. The researchers outlined their findings in a report to the California Energy Commission, which paid for the study with a $95,000 grant. (Earlier post.)
The researchers tested the “eco-routing” navigation system—which takes into account real-time traffic information, road type and road grade—on three routes around Riverside. Using road testing and computer simulations, they studied three types of navigation systems: shortest distance; least time; and least energy. They found energy savings between 25% and 51% when they took the route that the navigation system said would take the least amount of time. The tradeoff is that the travel distance increased between 3% and 19%.

Mechanical components—i.e., battery, motor, wiring, and suspension—are sourced from a variety of suppliers, including Renault’s Twizy, a line of electric-powered city cars.
Lux: Tesla likely to miss 2020 vehicle target by >50%; Gigafactory to bring only modest reduction in costs, >50% overcapacity
September 03, 2014
Lux Research forecasts that Tesla Motors’ Gigafactory—the announced new 35 GWh lithium-ion cell production facility that is the target of hot competition between five states (earlier post)—will bring about only a modest reduction in Li-ion battery costs and create significant overcapacity, given likely Tesla EV sales in 2020 of less than half of the company’s targeted 500,000.
Tesla and its partner, Panasonic, will contribute about 45% and 35%, respectively, of the initial $4 billion required to build the Gigafactory, proposed to go on-stream in 2017. Lux Research’s new report—“The Tesla-Panasonic Battery Gigafactory: Analysis of Li-ion Cost Trends, EV Price Reduction, and Capacity Utilization”—projects sales of some 240,000 Tesla cars in 2020, leading to razor-thin margins to Panasonic and 57% overcapacity.
California ARB considering modifications to ZEV regs to provide more flexibility for intermediate volume manufacturers
The California Air Resources Board (ARB) will conduct a public hearing on 23 October to consider amendments to the Zero Emission Vehicle (ZEV) regulation that would modify the requirements for intermediate volume manufacturers (IVMs) selling into the state to allow them more time to come into the advanced technology vehicle market.
The modifications to the ZEV rule, developed by the ARB staff to be presented to the Board at the meeting, provide additional compliance flexibility to the IVMs by providing additional production lead time; a reduced compliance obligation; an opportunity to pool compliance obligations in ZEV states; and additional time to make up ZEV credit deficits.

Study suggests OEMs should use a modular design for PHEV and EREV vehicle battery packs to offer capacity choices to customers
|TCO in € cents/km of EREV as a function of battery size for users with different annual mileages. Redelbach et al. Click to enlarge.|
Car manufacturers should develop a modular design for plug-in hybrid and extended range electric vehicles (PHEVs and EREVs), allowing them to offer a choice of storage capacity to meet individual customer requirements rather than forcing a “one size fits all” approach, according to the results of a German-market-specific TCO study by a team from the Institute of Vehicle Concepts, German Aerospace Center (DLR).
The authors of the study, published in the journal Energy Policy, stress that they are not suggesting OEMs offer each customer an individual battery size, but rather than they offer, as an example, three different battery sizes dedicated to drivers with low, average and high mileage. The development of a modular design for battery packs could help OEMs to change the size with less effort and few implications on the rest of the vehicle, they suggested. (This is analogous to the approach taken by Tesla Motors with its two—originally three—pack capacity sizes offered in the Model S.)

National Electric Vehicle Sweden (NEVS), the company working to resurrect the Saab brand, presented the Saab 9-3 Electric Vehicle as designed and produced as part of a prototype series in Trollhättan. NEVS halted production of the conventional Saab 9-3 Aero in May as it struggles to sort out its financing. (Earlier post.)
The EV prototype is a modified Saab 9-3 Aero Sedan in which the batteries are placed under the floor, keeping the full interior space as well as the luggage compartment intact. The car is equipped with lithium-ion batteries from Beijing National Battery Technology, a company within the Chinese group of green tech companies owned by Kai Johan Jiang’s company National Modern Energy Holdings Ltd.
U. Mich study: natural-gas-based ICE, BEV and FCV all show promise for environmental benefits relative to conventional ICE
August 19, 2014
Results of a lifecycle analysis by a team at the University of Michigan suggest that multiple types of natural gas-powered vehicles—i.e., natural-gas burning ICE vehicles; battery-electric vehicles (BEVs) recharged with gas-generated electricity; and fuel cell vehicles (FCVs) using hydrogen produced from natural gas—all show promise for reducing environmental impacts, energy demand and climate change impacts relative to conventional petroleum-fueled internal combustion engined vehicles for personal mobility.
Qiang Dai and Christian Lastoskie found that BEVs and FCVs in particular offer significant reductions in greenhouse gas emissions, especially if carbon capture and sequestration (CCS) technologies are implemented at the fuel conversion facilities. Their study appears in the ACS journal Energy & Fuels.
ORNL researcher suggests that most consumers better off with <100-mile EV range until battery costs drop to $100/kWh
August 18, 2014
Until battery cost is cut down to $100/kWh, the majority of US consumers for battery electric vehicles (BEV) will be better off by choosing an electric vehicle with a range below 100 miles, according to a new study by Oak Ridge National Laboratory (ORNL) researcher Zhenhong Lin.
The research, published in Transportation Science, a journal of the Institute for Operations Research and the Management Sciences (INFORMS), suggests reconsideration of the R&D goal that battery electric vehicles should have a driving range similar to that of conventional vehicles. It also implies that the focus of policy and R&D should be on continued reduction of battery costs to make short-range BEVs more price-competitive.

August 12, 2014
|Power savings in plug-in vehicles versus total savings per car. Source: Lux. Click to enlarge.|
Using wide bandgap (WBG) materials such as silicon carbide (SiC) and gallium nitride (GaN)s for power electronics can improve efficiency and thereby reduce the high cost of battery packs, according to a new report from Lux Research. In the new report “Silicon vs. WBG: Demystifying Prospects of GaN and SiC in the Electrified Vehicle Market,” Lux projects that SiC will be adopted in electric vehicles in 2020.
As silicon struggles to meet higher performance standards, WBG materials are benefiting critically from evolving battery economics. As an extreme example (because of the very large battery pack), Lux notes that on Tesla Model S, a 20% power savings could result in gains of more than $6,000 in battery cost—8% of the vehicle’s cost.
SCAQMD funding Siemens test of eHighway overhead catenary system for electric trucks in California
August 06, 2014
Siemens will conduct trials of its eHighway system (earlier post) in California on a two-mile (3.2 km) stretch of highway after installing a catenary system for electric and hybrid trucks in the vicinity of the largest US ports of Los Angeles and Long Beach.
The company was awarded the associated contract by Southern California’s South Coast Air Quality Management District (SCAQMD). The objective is to eliminate local emissions such as nitrogen oxides completely and to reduce the consumption of fossil fuels and cut the operating costs of trucks. The test results should be available in the summer of 2016, and will indicate the suitability of the systems for future commercial use.

August 01, 2014
For the second quarter for 2014, Tesla Motors reported non-GAAP net income of $16 million and a GAAP net loss of $62 million. Tesla includes both GAAP and non-GAAP financial information because it plans and manages its business using non-GAAP information. Non-GAAP financials exclude stock-based compensation and non-cash interest expense, while adding back the deferred revenue and related costs for cars sold with a residual value guarantee or similar buy-back terms.
Non-GAAP revenue was $858 million for the quarter, up 55% from a year ago, while GAAP revenue was $769 million. Automotive revenue for Q2 included $23 million of powertrain sales to Daimler and Toyota, reflecting the start of production deliveries to Daimler for the Mercedes-Benz B Class Electric Drive and the wind down of sales to Toyota for the RAV4 EV.
Panasonic and Tesla sign Gigafactory agreement
July 31, 2014
Panasonic Corporation and Tesla Motors, Inc. signed an agreement that lays out their cooperation on the construction of a large-scale battery manufacturing plant in the United States (the specific location yet to be announced) known as the Gigafactory. (Earlier post.) During Tesla’s Q4 earnings call in February, Tesla CEO Elon Musk had noted that because Panasonic is Tesla’s primary partner on battery production, the “default assumption” was that Panasonic would continue to partner with Tesla in the Gigafactory.
According to the agreement, Tesla will prepare, provide and manage the land, buildings and utilities. Panasonic will manufacture and supply cylindrical lithium-ion cells and invest in the associated equipment, machinery, and other manufacturing tools based on their mutual approval. A network of supplier partners is planned to produce the required precursor materials. Tesla will take the cells and other components to assemble battery modules and packs.

EPRI, 8 automakers and 15 utilities to create an open grid integration platform for plug-in electric vehicles
July 29, 2014
The Electric Power Research Institute, 8 automakers and 15 utilities are working to develop and to demonstrate an open platform that would integrate plug-in electric vehicles (PEVs) with smart grid technologies enabling utilities to support PEV charging regardless of location. The open platform will simplify and streamline V2G (vehicle-to-grid) communications, enabling PEVs to provide grid services and increasing the overall value proposition of plug-in vehicles.
The goal of this program is to develop a cloud-based, central server that would receive grid requests from a utility—such as Demand Response—and then translate and standardize that request so it could be relayed to all appropriate plug-in vehicles in the designated area. Automakers would be expected to develop and deploy technologies compatible with these smart grid communications.
Navigant forecasts global road transportation energy consumption to increase 25% by 2035; 84% from conventional fuels
July 28, 2014
In a new report (Transportation Forecast: Global Fuel Consumption), Navigant Research forecasts total road transportation energy consumption will grow from 81.1 quadrillion Btu in 2014 to 101.7 quadrillion Btu in 2035—an increase of 25.4%. Approximately 84% of that will be provided by conventional fuels. The United States is currently the largest consumer of energy in the road transportation sector, with nearly 23.1 quadrillion Btu projected to be consumed in 2014.
Navigant also projects that investments in alternative fuel and fuel efficiency improvements will reduce annual energy consumption in the United States year-over-year. Most developed countries in Western Europe and parts of Asia Pacific will also exhibit similar decreases in energy consumption. In contrast, energy consumption will grow in developing regions, particularly in Eastern Europe, Asia Pacific, Latin America, and the Middle East & Africa. Brazil, Russia, India, and China (the BRIC nations) will represent the largest increases, as the percentage of global road transportation energy consumed by these nations is forecast to grow from 20% in 2014 to 36% in 2035.
Study finds testing the technology the strongest initial motivation for fleet managers adopting EVs
July 25, 2014
According to a report from Frost and Sullivan (Kumar, 2013), fleet managers adopted more than half of EVs sold globally up to 2013. A new study of factors influencing fleet managers’ adoption of electric vehicles has found that testing new technologies was the strongest driver of initial EV adoption, followed by lowering environmental impacts; government grants; and improving the organization’s public image. Thereafter fleet managers adopted or indicated an intent to adopt a larger number of EVs because of the benefits that they offer.
The study by William Sierzchula at Delft University of Technology, published in the journal Transportation Research Part D, used fleet manager interviews and pilot project report to investigate 14 US and Dutch organizations that adopted EVs from 2010 to 2013 to determine which factors influenced their purchase decisions. In addition, Sierzchula also analyzed the reasons why these same firms did or did not expand their EV fleets.

July 24, 2014
The California Energy Commission gave final approval for nearly $50 million in grant awards for hydrogen refueling and electric charging construction projects recommended for funding in notices of proposed awards published in April and May.
California’s zero-emission vehicle goal is to get 1.5 million hydrogen, battery electric, and plug-in electric vehicles on the roadway by 2025. In response to this directive, the Energy Commission’s Alternative and Renewable Fuel and Vehicle Technology Program (ARFVTP) has already allocated nearly $400 million to help bolster statewide infrastructure and create a viable market for zero-emission vehicles (ZEVs), and to promote alternative fuels.
ABB and Volvo Buses partnering on fast-charging system for hybrid and electric buses
July 22, 2014
ABB and Volvo Buses are partnering to co-develop and to commercialize electric and hybrid buses with open standards-based direct current (DC) fast charging systems. The cooperation will create a city-wide standardized charging system for electric and electric hybrid buses that can charge buses quickly through an automatic roof-top connection system at bus stops or through cabled charging systems overnight.
This approach, based on internationally accepted standards (EN61851-23), enables maximum re-use of existing e-mobility technologies, thereby ensuring a rapid deployment of urban e-mobility. The first joint project will be the implementation of Volvo Electric Hybrids and ABB’s automatic e-bus chargers in the Luxembourg public transport system, where as many as 12 Volvo Electric Hybrid buses operated by Sales-Lentz will be running on existing lines by 2015.
Driving the VW e-Golf; strategy, assembly in Wolfsburg, Braunschweig battery plant
July 21, 2014
|The e-Golf. Click to enlarge.|
The e-Golf (“Das e-Auto” earlier post), the Volkswagen brand’s second series production battery-electric vehicle after the e-up!, is a key model, as it is the best and most current implementation of its strategic decision to begin providing e-mobility based on large-scale production models rather than special “small niche” cars. The Golf is core to Volkswagen; the company has sold more than 30 million units worldwide since the first introduction in 1974. The e-Golf is based on current 7th generation Golf, itself based on the strategic MQB toolkit.
Put another way, Volkswagen’s goal, based on its strategic approach, is for the e-Golf to deliver the performance and handling of a Golf which happens to have a battery-electric powertrain. Based on a second, and slightly longer, chance to drive the new e-Golf unsupervised, we think Volkswagen has succeeded splendidly in this goal; we find the e-Golf to be a nimble and quiet electric delight.
OpEneR: improving EV range by optimizing energy management
July 17, 2014
|OpEneR partners have developed driving strategies and driver assistance systems to improve the efficiency and safety of electric vehicles. Click to enlarge.|
At its final review, the European research project OpEneR (“optimal energy consumption and recovery based on a system network”) presented collaboratively developed driving strategies and driver assistance systems to improve significantly the efficiency (and hence range) and safety of electric vehicles by optimizing energy management. (Earlier post.)
In comparison to a typical sporty driver, the OpEneR operation strategies resulted in a reduced energy consumption of 27 to 36%, with the trade-off of an increase in travel time of between 8 to 21%—depending on the driver’s willingness to follow the recommendations. Approximately 5 percentage points of the energy consumption reduction were due to intelligent torque distribution between front and rear electric motors in the demonstrators, which had no influence on travel time at all.

July 11, 2014
|Silicon Carbide multiport DC-DC converter fitted to the Tata Vista EV. Click to enlarge.|
A consortium led by motorsport and technology company Prodrive has successfully run a silicon carbide-based multiport DC-DC converter in an electric car. The converter controls power flow between multiple energy sources and has been able to achieve efficiency of 98.7%, while increasing power density and reducing the size and weight of the converter when compared to silicon-based systems.
A key aspect of the converter is the use of silicon carbide devices. These operate at a much higher frequency than equivalent silicon components—at 75 kHz in the test vehicles—with a significant reduction in switching losses. This has resulted in a significant reduction in the size of the magnetic components and has enabled the converter to achieve an efficiency of 98.7%, a gravimetric power density of 10.5 kW/kg and a volumetric power density of 20 kW/liter.
Navigant forecasts MHD vehicle market to nearly double by 2035 with declining share of conventional engines; gases win out over electricity
July 07, 2014
The number of medium- and heavy-duty vehicles (MHDVs) in use worldwide will nearly double between 2014 and 2035, according to a new forecast report by Navigant Research. Navigant projects that annual MHDV sales will grow throughout the forecast period at a compound annual growth rate (CAGR) of 2.4%.
Alternative fuel vehicles (AFVs)—including battery-electric (BEVs), plug-in hybrid (PHEVs), propane autogas (PAGVs) and natural gas vehicles (NGVs)—will grow from 5.0% of the market in 2014 to 11.2% by 2035. A majority of these AFVs will be NGVs and PAGVs. Vehicles running primarily on hydrogen and electricity will make up less than 1% of all MHDVs in 2035, according to Navigant.
Toyota, Grenoble, EDF and Citélib launching Ha:Mo EV sharing service as part of multimodal transport solution; small EVs for the last kilometer
June 29, 2014
In October 2014, a car charing service featuring 70 Toyota i-ROAD and COMS ultra-compact electric vehicles and around 30 charging stations developed and managed by EDF’s subsidiary Sodetrel will be open for service for a period of three years through a unique partnership between the City and the Metropolitan Area of Grenoble (France), French energy company EDF, Japanese car maker Toyota and Citélib, a local car-sharing operator. (Earlier post.)
Connected to the public transport system’s IT infrastructure, this new car-sharing scheme will complement Citélib, the current car-sharing service of Grenoble, by allowing users to pick up one of the small EVs at one location and drop it off at another. The project also aims to promote multimodal transport methods. The main idea is to allow commuters to drive electrically the first or last kilometers of their journey for increased flexibility and time-saving, thus contributing to reducing traffic congestion and improving air quality in city centers.
