GM provides technical details of the Gen 2 Voltec propulsion system used in the 2016 Volt
April 23, 2015
The second-generation “Voltec” extended range electric powertrain applied in the MY2016 Chevy Volt (earlier post) marks a significant evolution in the electric drive technology platform from its first-generation origins. After proving a initial look at the design and capability of the different components (earlier post) late last year, GM is now providing deeper technical insight into the second-generation platform.
At the SAE 2015 World Congress in Detroit this week, GM engineers are presenting four papers on the technology of the Gen 2 Voltec propulsion system: an overview of the system and the realized improvements in efficiency and performance; a paper on the significantly re-engineered traction power inverter module (TPIM); a paper on the design and performance of the new electric motors used in the propulsion system; and a paper on the selection and design of the optimized gasoline-fueled 1.5-liter range extender engine.
NRC report recommends ways to overcome barriers hindering purchases of PEVs; vehicle cost, battery tech and consumer knowledge among others
April 22, 2015
Vehicle cost, current battery technology, and inadequate consumer knowledge are some of the barriers preventing widespread adoption of plug-in electric vehicles, according to a new congressionally mandated report from the National Research Council. Developing less expensive, better performing batteries is essential to reducing overall vehicle cost, and a market strategy is needed to create awareness and overcome customer uncertainty, the report finds. The report recommends a range of incentives that the federal government can offer to address these and other barriers.
The premise of the report—“Overcoming Barriers to Deployment of Plug-in Electric Vehicles”—is that there is a benefit to the United States if a higher fraction of vehicle miles traveled is fueled by electricity rather than by petroleum due to the resulting reduction in dependence on petroleum and reduction in emissions of greenhouse gases and criteria pollutants. The task of the committee of experts and stakeholders writing the report was (1) to identify market barriers slowing the purchase of PEVs and hindering the deployment of supporting infrastructure in the United States and (2) to recommend ways to mitigate those barriers.

CMU study finds controlled EV charging can reduce generation cost, but at greater health and environmental costs depending upon the generation mix
April 16, 2015
In a study focused on the PJM portion of the US electricity grid, researchers at Carnegie Mellon University (CMU) found that although charging electric vehicles at night (when electricity is cheap and wind power is typically more plentiful) could lower electricity costs, doing so also creates more air emissions, and that the health and environmental costs from these emissions outweigh the electricity cost savings. A paper describing the work is published in the ACS journal Environmental Science & Technology.
Results from the study also suggest that with sufficient coal plant retirement and sufficient wind power, controlled charging could result in positive net benefits instead of negative. The result of the analysis depends on the details of the region, notes CMU Professor Jeremy Michalek, corresponding author—i.e., other parts of the US and the world could be different. The question of electricity costs vs. health and environmental cost is important to ask everywhere, Michalek said.
Cadillac boosts performance of ELR plug-in hybrid for MY2016, cuts MSRP by $9K; $58,495 net after Fed credits
April 15, 2015
Cadillac has greatly enhanced the performance of its ELR extended range electric vehicle (plug-in hybrid) (earlier post) for the 2016 model year, and is also cutting the MSRP by $9,005, bringing the starting price down to $58,495 net after the $7,500 US federal tax credit (MSRP = $65,995). MSRP for MY2014 was $75,000, with a net price of $67,500 after the Federal credit. (Cadillac sold 1,310 units of the ELR in the US in calendar year 2014, and sold 311 units in the first quarter of 2015.)

Visio.M partners showcasing energy efficient passenger climate control for EVs
As part of the German Federal Ministry for Education and Research (BMBF) collaborative project Visio.M (earlier post, earlier post), scientists of the TU München have developed an energy efficient solution for passenger climate control in EVs. The researchers are presenting the results of their work, as implemented in the Visio.M prototype vehicle, in the German government stand at the Hannover Messe.
In a combustion-engined vehicle, waste heat could be used to heat the vehicle passenger compartments directly. Many electric vehicles simply took over concepts from the combustion engined vehicles—e.g., a heater and an air conditioner. However, the energy drain of this approach can put a noticeable dent in vehicle range. The Visio.M researchers thus took a new look at all potential solutions, considering their efficiency, comfort and cost.

Recent legislation extended the ARFVTP until 1 January 2024.
CEC awards Proterra $3M toward electric bus manufacturing plant; Foothill Transit orders 13 more buses
The California Energy Commission (CEC) awarded a $3-million grant to leading battery-electric bus manufacturer Proterra as one of 46 transportation, energy storage, biogas and efficiency projects receiving a total of $83.7 million in grants and loans. The grant to Proterra will fund the design, development and construction of Proterra’s new battery-electric transit bus manufacturing line in California. The plant will be Proterra’s second after its original plant in Greenville, SC; the company said that its expansion was prompted by the strong growth in market demand for the new Proterra Catalyst electric buses.
Concurrent with the award, Proterra announced that Foothill Transit, the primary public transit provider of the San Gabriel and Pomona valleys in California, has ordered an additional 13 Proterra buses to be delivered in 2016; this is Foothill Transit’s fourth order from Proterra in five years. This latest order is Foothill’s largest order to date, bringing the all-electric fleet to about 30—nearly 10% of the transit agency’s total. Foothill Transit will also become the first customer for Proterra’s new extended-range vehicle, the Proterra Catalyst XR. (Earlier post.)
Roland Berger: China is the frontrunner in e-mobility subsidies; sales of xEVs double in Q1
April 03, 2015
China is currently subsidizing the development of e-mobility, making just under €7.7 billion (US$8.4 billion) available in the period to 2016, and is the global frontrunner in e-mobility subsidies by far, according to the Q1 2015 E-Mobility Index published by consultancy Roland Berger. The report also found that while Japan increased its subsidies slightly to €171 million (US$187 million) through 2016, most of the major automotive nations have seen the public subsidization of e-mobility decline dramatically. The US and Italy offer the least subsidization.
The index, prepared by Roland Berger and fka experts, compares the relative competitive standings of the top seven automotive nations (Germany, France, Italy, the USA, Japan, China and South Korea) in the electromobility segment. The outcome is based on analysis of three indicators: technology, industry and market.
U Toronto LCA suggests that with CNG as primary vehicle energy source, EVs best targeted at non-attainment areas
April 01, 2015
A team at the University of Toronto has examined the life cycle air emissions (climate change and human health) impact benefits and life cycle ownership costs of compressed natural gas (CNG) use directly in conventional vehicles (CV) and hybrid electric vehicles (HEV), and natural gas-derived electricity (NG-e) use in plug-in battery electric vehicles (BEV), using a gasoline-fueled conventional vehicle as a reference.
Among their findings, published in a paper in the ACS journal Environmental Science & Technology, are that policies should for the foreseeable future focus on the niche adoption of plug-in vehicles in non-attainment regions, as CNG vehicles are likely more cost-effective at providing overall life cycle air emissions impact benefits.

Berkeley Lab/UC Berkeley study shows EV batteries meet daily travel needs of 85%+ of US drivers even after 20% energy capacity fade; calls for new EOL criteria
March 31, 2015
A new study by researchers from Lawrence Berkeley National Laboratory (Berkeley Lab) and UC Berkeley shows quantitatively that EV batteries can continue to meet daily travel needs of drivers well beyond the 80% floor for remaining energy storage capacity that is commonly assumed. An open access paper on their work, which applied detailed physics-based models of EVs with data on how drivers use their cars, is published in the Journal of Power Sources.
The study also sheds light on a number of other factors concerning battery use and energy and power fade, including that even EV batteries with substantial energy capacity fade continue to provide sufficient buffer charge for unexpected trips with long distances; that enabling charging in more locations, even if only with 120 V wall outlets, prolongs the useful life of EV batteries; and that EVs meet performance requirements even down to 30% remaining power capacity.

Lux Research: the $40,000, 200-mile-range EV is the biggest coming growth opportunity for energy storage in transportation
Analysis by Lux Research suggests that the market space represented by the emerging lower-cost, 200-mile-range EV will be the biggest coming growth opportunity in electric storage for transportation. By 2020, this new EV battleground should account for $5 billion or more in Li-ion battery sales, because it combines larger packs (around 50 kWh) with more sales (hundreds of thousands of vehicles).
According to Lux Research’s Automotive Battery Tracker, in 2014 EVs used $2.1-billion worth of energy storage. While selling in similar volumes, plug-in hybrids (PHEVs) used three times less batteries: about $0.7 billion worth. Despite selling about 1.5 million units in 2014, an order of magnitude more than the 140,000 EVs that consumers bought in 2014, HEVs also used just $0.7-billion worth of energy storage in 2014.

SDG&E piloting integration of EVs and energy storage systems into CAISO energy markets for demand response services
In a pilot vehicle-to-grid project, San Diego Gas & Electric (SDG&E) is actively bidding a group of energy storage systems and electric vehicle fleets as one resource directly into the California Independent System Operator’s (CAISO) energy markets. These markets include those that address short-term imbalances in electricity supply caused by such things as intermittent renewable energy. This marks SDG&E as one of the first utilities to integrate EVs into California’s wholesale energy market.
The project currently aggregates stationary storage systems together with the charging demand of EV fleets at five separate locations throughout San Diego County. The assets are remotely controlled using software that both balances the participant’s charging needs, and identifies opportunities to provide demand response services at the grid level.
CMU, Ford, Drexel study suggests Chinese more receptive to adopting BEVs than Americans, regardless of subsidies
February 23, 2015
Results from a study by a team from Carnegie Mellon University, Ford and Drexel University suggest that Chinese consumers are more receptive to adopting battery-electric vehicles (BEVs) than their American counterparts, regardless of subsidies. The study is published in the journal Transportation Research Part A.
The team modeled consumer preferences and willingness to pay (WTP) for conventional, hybrid electric, plug-in hybrid electric (PHEV), and battery electric (BEV) vehicle technologies in China and the US using data from choice-based conjoint surveys fielded in 2012–2013 in both countries. They found that find that gasoline vehicles continue to be most attractive to consumers both countries, and that American respondents have significantly lower relative willingness-to-pay for BEV technology than Chinese respondents. Although plug-in subsidies in the US and Chinese subsidies both favor vehicles with larger battery packs, differences in consumer preferences lead to different outcomes, they found.
Libertine LPE free piston technology targeting power generation, waste-heat recovery and range-extended EV applications; feasibility study with PETRONAS
February 19, 2015
UK startup Libertine LPE has developed a free piston linear power generator technology that it says overcomes the key challenges faced by earlier free piston engine schemes of motion control, emissions and power conversion efficiency. The company, which on 16 Feb won the €20,000 (US$22,800) Climate-KIC cash prize at this year’s Cleantech Innovate, will be presenting its Linear Power Systems technology to investors at CleanEquity Monaco from 5-6 March.
A number of groups have recently or are currently investigating the use of free piston engine power generation applications with a focus on automotive, including work at West Virginia University (WVU), Sandia National Laboratory (SNL), Chalmers University of Technology (Sweden), and Shanghai Jiaotong University.

An adage about batteries is that they are like humans in performing best at moderate (e.g., room) temperatures; extremes in either direction impact performance. Thus, the efficiency of battery electric vehicles can vary with ambient temperature due to battery performance—as well as the energy required for cabin climate control.
In a new paper accepted for publication in the ACS journal Environmental Science & Technology, Tugce Yuksel and Jeremy Michalek at Carnegie Mellon University have now characterized the effect of regional temperature differences on EV efficiency, range, and use-phase CO2 emissions in the US, based on aggregated real-world fleet data for the Nissan LEAF. Among their findings is that the resulting regional differences in efficiency, range and emissions are large enough to affect adoption patterns and the energy and environmental implications of battery EVs relative to alternatives.

(Earlier post.) This program is one component of the $10-million commitment Volkswagen is making to support the build-out of the electric vehicle charging infrastructure.
PG&E proposes major build-out of 25,000 electric vehicle charging stations in California
February 09, 2015
Pacific Gas and Electric Company (PG&E) has filed an application with the California Public Utilities Commission (CPUC) for permission to build an estimated 25,000 electric vehicle (EV) chargers at sites across its service area in Northern and Central California—8 times the number currently installed. If approved, this program would be the largest deployment of EV charging stations in the country, PG&E said.
The cost of the plan would be shared by all electric customers as a contribution to helping the state meet its clean air and climate goals. The total impact on system average bundled rates would be minimal in 2016 and 2017 and would average only a tenth of a cent per kilowatt-hour over the next five years of the program. A typical residential customer would pay about 70 cents more per month over the period 2018 to 2022, according to PG&E.

The consortium is now putting the individual parts together to make a demonstrator. After that, they want to fit the axle module into a real vehicle for testing by the end of 2015.
Lux Research: despite cheap oil, niche plug-in vehicle sales will be resilient; conventional hybrids to be hardest hit
The current plunge in oil prices will likely negatively affect plug-in and hybrid vehicle sales in the short term; automakers such as BMW are already warning of lower sales of plug-in vehicles given the market context. However, an analysis by Lux Research suggests that despite some decrease in sales, sales of plug-in vehicles will likely be resilient, and rebound as oil prices rise back to the prior higher levels over time.
In the likely case of only a gradual return to previous higher prices—which Lux calls the “cheap oil” scenario in its analysis—then electric vehicle (EV) sales will dip by 20% for a number of years, while plug-in hybrid (PHEV) sales will dip by about 14% during that same period, the research firm found. The forecast declines are relative to the other forecasted scenario, in which oil prices rebound much more quickly—the “stable oil” scenario.

These include fuels such as biogas, hydrogen and renewable synthetic gases produced with low lifecycle GHG emission approaches.
Study finds vertical force of in-wheel switched reluctance motors deteriorates vehicle stability and comfort
January 27, 2015
In a study investigating switched reluctance motors (SRMs) for in-wheel motor applications, researchers at Chongqing University in China have found that the vertical component of the residual unbalanced radial force of the motor deteriorates the lateral and anti-rollover stabilities of the vehicle in addition to having a considerable impact on vehicle comfort. (The unbalanced radial force is the radial force difference between a pair of opposite stator poles.)
In their paper, published in the Proceedings of the Institution of Mechanical Engineers, Part D: Journal of Automobile Engineering, they suggest that a control method addressing these issues will be needed if SRMs are to see use in in-wheel applications. In an earlier paper, members of the team had proposed the use of an FxLMS (filtered-X least mean square) controller based on active suspension system to generate controllable force to suppress the vibration caused by SRM vertical force. In that paper, they found that utilizing active suspensions could reduce the effect of SRM vertical force on suspension performance.

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.

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.
Quick drive of the Passat HyMotion hydrogen fuel cell hybrid
November 20, 2014
Volkswagen unveiled the Golf Sportwagen HyMotion hydrogen fuel cell hybrid research vehicle demonstrator yesterday at the Los Angeles Auto Show (earlier post). Volkswagen has also built several research vehicles based on the US version of the Passat using the same hydrogen drivetrain components as fitted in the Golf SportWagen HyMotion.
The fleet of Passat HyMotion vehicles is currently being tested on the streets of California. In addition, Volkswagen brought a pair of the hydrogen Passats to the Los Angeles Auto Show for test drives (and Audi brought a pair of its A7 Sportback h-tron hydrogen fuel cell plug-in hybrids for drives, as well.)

The 42-vehicle fleet marks a milestone in partnership between federal, state and private energy organizations, as well as in DoD’s demonstration of emerging vehicle-to-grid technology.
The PEV fleet includes both electric and hybrid vehicles ranging from sedans to trucks and a 12-passenger van. California energy providers and regulators worked closely with the Air Force on safety and performance testing as well as technical and regulatory aspects of launching the vehicles.
Tesla delivers record 7,785 Model S units worldwide in Q3; non-GAAP net of $3M, GAAP loss of $75M
November 06, 2014
Tesla reported third-quarter global deliveries of 7,785 Model S units, despite a factory shutdown in July; this included the highest ever peak deliveries in a single day of 907 vehicles. The majority of Q3 delivers were in North America. (Tesla does not fully break out its sales by country, nor does it provide monthly sales reports.) The company also reported that Model X deliveries would start in Q3 2015, later than the previously revised target.
Based on orders since the introduction of Dual Motor all-wheel drive and “Autopilot” (earlier post), Tesla management said it was confident of a 50% increase in both net orders and deliveries for Model S alone in 2015. While Tesla is not planning major platform changes to the hardware in the near term, there will be several “significant” over-the-air software releases that add functionality.
Navigant forecasts modest global annual sales growth of e-bicycles, reaching 40.3M units in 2023
November 05, 2014
In a new report, Navigant Research forecasts that global annual sales of e-bicycles will grow modestly from 31.7 million units in 2014 to 40.3 million units in 2023 under a base scenario—a CAGR of 2.7%. Navigant expects China, the market leader, to reach 28.8 million e-bicycle sales this year under the base scenario, representing 91% of the total global market. 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.
La Poste Group and Renault enter new eco-mobility partnership; coincides with delivery of the 5,000th Kangoo Z.E.
Philippe Wahl, Chairman and Chief Executive Officer of La Poste group, and Carlos Ghosn, Chairman and Chief Executive Officer of the Renault group, signed a new partnership agreement today to pursue and strengthen their cooperation on the search for eco-mobility solutions. Since the launch of France’s low-carbon vehicle project in January 2009, La Poste group, which has the country’s largest industrial fleet with some 69,000 vehicles, has equipped itself with a complete range of electric vehicles, including small light commercial vehicles, quads, three-wheelers and electrically assisted bicycles. Today, La Poste mailmen and mailwomen use nearly 25,000 means of electric transport daily.
The Renault group and La Poste group are working together in a wide range of fields on forward-looking issues independently of their business relations. By signing the new partnership agreement, the two French companies are pursuing their collaborative efforts on the search for eco-mobility solutions. Through research work and studies, the two groups will develop pilot projects on new mobility solutions and continue to foster the sustainable mobility of the present and future, focusing on four main areas:
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.
European Council endorses 40% GHG cut by 2030; requests ways to cut transport emissions via efficiency, electrification and renewable fuels
October 24, 2014
On 23 October, leaders of the European Union agreed on the climate and energy policy framework for the EU for the period from 2020 to 2030. During its meeting, the European Council endorsed 4 targets: a binding EU target of at least 40% less greenhouse gas emissions by 2030, compared to 1990; a binding target of at least 27% of renewable energy used at EU level; an energy efficiency increase of at least 27%; and the completion of the EU-internal energy market by reaching an electricity interconnection target of 15% between members states and pushing forward important infrastructure projects.
The Council members also requested further examination by the European Commission on instruments and measures for a comprehensive and technology-neutral approach to reduce emissions and increase energy efficiency in transport, for electric transportation and for the use of renewable energy sources in transport after 2020.
8 ZEV states announce US ZEV sales top 260,000 units
October 23, 2014
Representatives of an eight-state partnership to develop and to support the market for zero emission vehicles (ZEVs) joined California Air Resources Board Chairman Mary D. Nichols in Diamond Bar, California to announce that sales figures from around the country now show ZEV sales of more than 260,000 vehicles, with the quarter-million mark reached in September.
In October 2013, the 8 states signed a memorandum of understanding to take specific actions to put 3.3 million ZEVS on the roads in their states by 2025 (earlier post); the partners released a ZEV Action Plan in June 2014 (earlier post). 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 partners present new lightweight EV; 13.5 kWh pack delivers ~100 mile range
October 20, 2014
|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.
Nissan begins testing combination of LEAF EVs and “LEAF to Home” for grid demand response services
October 16, 2014
Nissan Motor Corporation has begun testing in Japan of a system to use electric vehicle technology to help power grids cope with peaks in demand.
Nissan is using Nissan LEAF EVs paired with the LEAF to Home power supply system (earlier post) for demand response testing at several of its sales outlets run by subsidiary Kanagawa Nissan Co., Ltd. to assess the effectiveness of EV batteries when used for energy management. The tests are being conducted by ENERES Co., Ltd.
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.
EPRI and partners to stage public demo of Open Vehicle-Grid Integration (VGI) Platform software
October 14, 2014
The Electric Power Research Institute (EPRI), along with several auto manufacturers, utilities, and regional transmission organizations, will demonstrate the Open Vehicle-Grid Integration (VGI) Platform software system, developed by EPRI and Sumitomo Electric Industries. The software is an advanced software platform for integrating plug-in electric vehicles (PEV) with smart grid technologies. (Earlier post.)
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.
