October 21, 2014
|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.

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.

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.

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.
Tesla adds 2-motor all-wheel drive and advanced driver assistance “Autopilot” to Model S
Tesla Motors is adding a two-motor all-wheel drive option for its electric Model S as well as a standard set of forward-looking camera, radar and 360˚ ultrasonic sensors that will, over time with software updates, provide increasing autonomous drive capabilities.
The two-motor all-wheel drive option—designated by the “D” teased by Elon Musk over which the Internet was all atwitter—is available on all three Model S variants (60, 85 and P85) at $4,000 for the 60D and 85D models and as a $14,600-option for the P85D. (The high performance P85D requires the Tech Package, Smart Air Suspension and 21" wheels as well.) D-model deliveries begin in February.

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.

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.

|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.

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.

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.

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.

Consortium successfully runs silicon carbide multiport DC-DC converter in EV
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.

Study finds V2G-capable electric school buses cost-effective with current technology; financial and environmental benefits
Electric school bus fleets with vehicle-to-grid (V2G) capabilities are cost-effective with today’s technology, and could save schools money while reducing greenhouse gas emissions and improving public health, according to a new study by a team at the University of Delaware’s College of Earth, Ocean, and Environment (CEOE).
Lance Noel and Regina McCormack conducted a cost-benefit analysis of owning and operating a V2G-capable electric school bus, and compared its cost-effectiveness to a traditional diesel school bus. They analyzed several factors, including fuel expense, electricity and battery costs, health externalities, and frequency regulation market price. The V2G-capable electric bus provides the school savings of $6,070 per seat in net present value ($230,000 per bus over the vehicle’s 14-year lifespan) and becomes a net present benefit after five years of operation. Without externalities (e.g., medical and climate change costs), the net present benefit would be $5,700 per seat.

Navigant forecasts plug-in and fuel cell vehicles to be 2.5% of all vehicles in use in 2035; global parc of >2B vehicles
May 20, 2014
In a new report, Navigant Research estimates that nearly 84.1 million new light-duty vehicles (LDVs) will be sold globally in 2014, putting more than 1.2 billion vehicles on the world’s roads. The company forecasts that annual LDV sales will grow to 126.9 million in 2035, representing a compound annual growth rate (CAGR) of 2.0%. The number of LDVs in use worldwide will grow by 72.4% over the forecast period—i.e., to more than 2 billion vehicles.
Navigant forecasts that sales of conventional ICE vehicles will fall significantly over the period, experiencing a CAGR of -6.7%; the share of vehicles in use with conventional ICE powertrains will thus fall from 95% in 2014 to 45% in 2035. Navigant suggests that conventional ICE vehicles will be mainly supplanted by stop-start vehicles (SSVs), which will grow from representing fewer than 3% of vehicles in use in 2014 to around 45% in 2035. Hybrid-electric and natural-gas (HEVs and NGVs) will account for almost 8% of global share, while plug-in hybrid (PHEV), battery-electric (BEV), and fuel-cell electric (FCV) together will add up to almost 2.5% of the LDVs in use in 2035.

Toyota Central R&D developing free-piston engine linear generator; envisioning multi-FPEG units for electric drive vehicles
April 22, 2014
|Toyota’s FPEG features a hollow step-shaped piston, combustion chamber and gas spring chamber. Click to enlarge.|
A team at Toyota Central R&D Labs Inc. is developing a prototype 10 kW Free Piston Engine Linear Generator (FPEG) featuring a thin and compact build, high efficiency and high fuel flexibility. Toyota envisions that a pair of such units (20 kW) would enable B/C-segment electric drive vehicles to cruise at 120 km/h (75 mph). The team presented two papers on the state of their work at the recent SAE 2014 World Congress in Detroit.
The FPEG consists of a two-stroke combustion chamber, a linear generator and a gas spring chamber. The piston is moved by the combustion gas, while magnets attached to the piston move within a linear coil, thereby converting kinetic energy to electrical energy. The main structural feature of the Toyota FPEG is a hollow circular step-shaped piston, which Toyota calls “W-shape”. The smaller-diameter side of the piston constitutes a combustion chamber, and the larger-diameter side constitutes a gas spring chamber.
