Toyota has begun verification testing of its newly developed wireless battery charging system based on WiTricity technology. (Earlier post.)
Study finds 20-25% of EV range lost as psychological safety buffer; driver assistance systems could shrink that buffer
February 23, 2014
Between 20 to 25% of the potential range of an electric vehicle is lost as a psychological safety buffer, according to a study by a doctoral candidate at Technische Universität Chemnitz in Germany. The results of the study, which also suggested that assistance systems could reduce the size of that buffer, were based on more than 400,000 km (249,000 miles) of user experience gathered in the research project “MINI E Berlin powered by Vattenfall”. (Earlier post.)
The MINI E project was funded by the German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety. The Professorship of Cognitive and Engineering Psychology of TU Chemnitz was involved in the project from the start, alongside with BMW and Vattenfall and other university partners. During the field study a total of 79 users drove the MINI E for six months. The psychologists of TU Chemnitz conducted qualitative interviews at several points in time. In addition, questionnaires, diary methods and data loggers were used.

At BMW’s Efficient Dynamics Innovation Days 2014 in Germany, the company provided the first opportunities for test-driving the BMW X5 eDrive plug-in hybrid (PHEV) prototype (earlier post). BMW also presented the first four-cylinder member of its new EfficientDyanamics engine family—the 2.0-liter unit would serve as the engine component in a future production X5 eDrive PHEV—as well as ideas for future solutions in the field of lightweight design, aerodynamics and thermal management.
Powertrain technology is key to BMW’s EfficientDynamics strategy, with a dual focus on the continuous evolution of conventional internal combustion engines on the one hand and the development of alternative drive concepts on the other. As well as achieving significant emissions reductions based on continuous evolutionary advances of the TwinPower Turbo gasoline and diesel engines, future BMW core brand models will also benefit from the transfer of new electrified drive technology (BMW eDrive) developed by the BMW i sub-brand.
Study finds that EV-specific factors rather than socio-demographic variables better predictors of EV uptake
February 19, 2014
A study by researchers at the Delft University of Technology (The Netherlands) examining the impact of financial incentives and other socio-economic factors on electric vehicle (both plug-in hybrids and battery electrics) adoption in 30 countries found that financial incentives; the number of charging stations (corrected for population); and the presence of a local manufacturing facility were positive and significant in predicting EV adoption rates for the countries studied.
Of those, charging infrastructure was the best predictor of a country’s EV market share. However, the team cautions in their paper in Energy Policy, descriptive analyses indicated how country-specific factors such as government procurement plans or the target recipient of subsidies can significantly affect the adoption rate. In other words, neither financial incentives nor charging infrastructure ensure high electric vehicle adoption rates. However, on the whole, they conclude, the analysis tentatively endorses financial incentives and charging infrastructure as a way to encourage EV adoption.
Toyota to begin wireless vehicle charging system verification testing
February 13, 2014
Toyota Motor Corporation (TMC) will begin verification testing of its newly developed wireless battery charging system for plug-in electric vehicles—such as plug-in hybrids and battery-electric vehicles—in late February in Aichi Prefecture, Japan. The system can charge a vehicle parked in alignment over a coil on the surface of the ground, making the charging process simpler and more convenient.
The charging system uses magnetic-resonance technology, which transmits electricity by utilizing the magnetic resonance resulting from changes in magnetic field intensity between a coil on the ground that transmits and a coil on the vehicle that receives.

CMU researchers find controlled charging of PHEVs can cut cost of integration into electricity system by 54-73%; higher benefits with wind power
January 24, 2014
In a new study published in the journal Applied Energy, Carnegie Mellon University (CMU) researchers found that controlled charging of plug-in hybrid electric vehicles (PHEVs) reduces the costs of integrating the vehicles into an electricity system by 54–73% depending on the scenario.
More specifically, controlled charging can cut the cost of integrating PHEVs approximately in half. The magnitude of these savings is ~5% to 15% higher in a system with 20% wind penetration compared to a system with no wind power, and the savings are 50–60% higher in a system that requires capacity expansion.

Mayor of London: all new London taxis will need to be zero-emission capable from 2018
January 16, 2014
The Mayor of London, Boris Johnson, announced plans that would require all new taxis presented for licensing in the capital to be zero-emission capable from 1 January 2018, with the expectation that they will automatically operate in zero-emission mode while in areas where the capital’s air quality is at its worst—such as parts of central London.
The Mayor confirmed his plan at Transport for London’s (TfL’s) “New Taxis for London” event, at which he met five manufacturers developing zero emission capable taxis—Frazer-Nash, Nissan, Karsan, London Taxi Company and Mercedes-Benz. The new zero-emission capable taxis being developed include both plug-in full series hybrid vehicles and full electric models.
Comprehensive modeling study finds electric drive vehicle deployment has little observed effect on US system-wide emissions
January 15, 2014
The results of a new, comprehensive modeling study characterizing light-duty electric drive vehicle (EDV) deployment in the US over 108 discrete scenarios do not demonstrate a clear and consistent trend toward lower system-wide emissions of CO2, SO2, and NOx as EDV deployment increases.
As explained in their paper published in the ACS journal Environmental Science & Technology, the researchers from North Carolina State Univesity and the University of Minnesota found that, while the scenario parameters can influence EDV deployment—even to a most extreme scenario of adoption—this EDV deployment does not in turn produce a discernible effect on total system-wide emissions. There are three reasons for this lack of observed effect, they concluded: (1) at present the overall share of emissions from the LDV sector is only 20% of US CO2 emissions; (2) EDV charging can still produce comparable emissions to conventional vehicles depending on the grid mix; and (3) the effect of other sectors on emissions is significant.

A newly-released report by the Center for Automotive Research (CAR) concludes that the automotive industry is not only “high-tech,” it is frequently a leader in technological developments and applications. The report, supported by the Alliance of Automobile Manufacturers, measures the technological nature of today’s auto industry and compares it to other sectors of the economy often viewed as technologically advanced.
The report authors acknowledge the difficulty of defining “high-tech” in an ever-changing economic environment. After reviewing of the works of several researchers and government agencies, CAR developed a working definition to differentiate high-tech industries from other sectors. Broadly, high-tech industries generally have the following characteristics:
Navigant Research forecasts new EV global sales of > 346,000 units in 2014; 10 predictions for the year
During 2014, the global plug-in electric vehicle (PEV) industry is poised to grow by 86% and will surpass more than 346,000 new vehicles sold, according to a new white paper—“Electric Vehicles: 10 Predictions for 2014”—published by Navigant Research. This would bring the global total of PEVs on the road to more than 700,000 by the end of the year, according to the firm’s calculations.
Broadly, Navigant expects expansion in both the higher end of the market (thereby putting competitive pressure on Tesla Motors), as Audi, BMW, Cadillac, Mercedes, Saab, and Volvo introduce their first plug-in cars. More mainstream models will come from Kia, Mahindra, Škoda, and Volkswagen. North America, Europe, and Asia Pacific will continue to drive PEV sales, as the technology will have only limited availability in the emerging markets of Latin America and Africa.
Researchers call for major change in US policies supporting plug-ins; failure of “mainstream consumer bias”
January 06, 2014
Although sales of plug-in vehicles (plug-in hybrid-electric and battery-electric vehicles, collectively PEVs) in the US climbed more than 80% in 2013 to more than 96,000 units (Tesla has not yet released its final figures) from 52,835 units in 2012 EDTA), the 2013 results still reflect a meagre new light-duty vehicle market share of ~0.6% for PEVs.
In a paper published in the journal Energy Policy, Erin Green of Green Energy Consulting; Steven Skerlos of the University of Michigan; and James Winebrake of the Rochester Institute of Technology argue that current US policies intended to promote the uptake of plug-in electric vehicles haven proven inefficient and ineffective. Suggesting that “mainstream consumer bias” is an explanation for the policy deficiencies that have resulted in slower than expected market penetration of PEVs, they propose an alternative policy agenda including the leveraging of strategic market niches, targeted R&D and incentives, and loans.

January 03, 2014
|WTW energy demand and GHG emissions for EV and PHEV drivetrains for various electricity sources; gasoline ICE vehicle is solid square, hybrid the hollow square. Click to enlarge.|
A comprehensive analysis of well-to-wheel (WTW) primary energy demand and greenhouse gas (GHG) emissions for the operation of conventional and alternative passenger vehicle drivetrains in Switzerland has concluded that alternative combustion fuels—not only alternative drivetrains such as PEVs or FCVs—play an important role in the transition towards low-emission vehicles.
The study by a team at the Swiss Federal Institute of Technology Zurich, reported in the Journal of Power Sources, is novel in three respects, the researchers said. First, it considers the performance of both mature and novel hydrogen production processes, multiple electricity generation pathways and several alternative drivetrains. Second, it is specific to Switzerland. Third, the analysis offers a novel comparison of drivetrain and energy carrier production pathways based on natural resource categories.
Ford unveils C-MAX Solar Energi concept; “plug-in” hybrid not dependent on electric grid can fully recharge from sun
January 02, 2014
Ford Motor Company announced the C-MAX Solar Energi Concept, a sun-powered hybrid vehicle that can deliver the efficiency of a plug-in hybrid without depending on the electric grid for recharging. Instead of recharging its battery from an electrical outlet, Ford C-MAX Solar Energi Concept uses a special Fresnel lens-based solar concentrator as a stationary canopy working with solar panels on the vehicle roof to recharge directly from the sun.
The concept vehicle uses a day’s worth of sunlight to deliver the same performance as the conventional C-MAX Energi plug-in hybrid (earlier post), which draws its power from the electric grid. Ford C-MAX Energi gets a combined EPA-estimated 108 MPGe city and 92 MPGe highway, for a combined 100 MPGe. C-MAX Solar Energi Concept, which will be shown at the 2014 International CES in Las Vegas, is a collaborative project of Ford, SunPower Corp. and Georgia Tech.

EIA: light duty vehicle energy consumption to drop 25% by 2040; increased oil production, vehicle efficiency reduce US oil and liquid imports
Reflecting slow growth in travel and accelerated vehicle efficiency improvements, US light-duty vehicle (LDV, cars and light trucks) energy use will decline sharply between 2012 and 2040, according to the US Energy Information Administration’s (EIA’s) Annual Energy Outlook 2014 (AEO2014) Reference case released today.
AEO2014 includes a new, detailed demographic profile of driving behavior by age and gender as well as new lower population growth rates based on updated Census projections. As a result, annual increases in vehicle miles traveled (VMT) in LDVs average 0.9% from 2012 to 2040, compared to 1.2% per year over the same period in AEO2013. The rising fuel economy of LDVs more than offsets the modest growth in VMT, resulting in a 25% decline in LDV energy consumption decline between 2012 and 2040 in the AEO2014 Reference case.

Anderman report sees strongest growth for full-hybrid systems; Li-ion batteries for hybrids may be in short supply
November 22, 2013
Low-cost 14V micro hybrid systems and full (strong) hybrid (i.e., systems with limited electric drive) architectures at 140-300V are entering strong growth phases, while the future of intermediate systems—those falling between the high-voltage full hybrids and the low-voltage stop-start systems—is less clear, according to “Assessing the Future of Hybrid and Electric Vehicles: The 2014 xEV Industry Insider Report” by Dr. Menahem Anderman of Advanced Automotive Batteries (AAB), to be released next week.
The 170-page report also finds that while the combined global EV and plug-in Hybrid (PHEV) market share is expected to grow to about 1.5% of total vehicle sales by 2020, the more significant story is the rapid expansion of strong-hybrid vehicles led by Toyota, Ford, and Honda, followed by Hyundai, Nissan and others. The current market share in Japan already exceeds 20%, and the world market share is estimated to exceed 5% by 2020.

SAE International J2954 Task Force for Wireless Power Transfer (WPT) of Light Duty, Electric and Plug-in Electric Vehicles, has agreed upon two key factors for the Technical Information Report (TIR) on interoperability for the first phase of pre-commercial development: a common frequency of operation (85 kHz) and the definition of three power classes for light duty vehicles: WPT 1, 2 and 3.
Made up of OEMs, WPT Suppliers, industry experts and government representatives, the Task Force plans to complete the TIR in early 2014. The SAE Technical Information Report will be followed by publication of SAE J2954 Standard, based on field data confirmation.
NCSU team proposes new system for dynamic wireless EV charging
Researchers from North Carolina State University are proposing a new topology appropriate for dynamic wireless charging—i.e., wireless charging on the go. Currently, at peak efficiency, the new system can transmit energy at a rate of 0.5 kilowatts (kW). The team’s goal is to move from 0.5 kW into the 50 kW range.
The system, outlined in a paper published in IEEE Transactions on Power Electronics, features a transmitter made from segmented multiple coils, each of which broadcasts a low-level electromagnetic field and is powered by a single inverter. A receiver coil that is the same size as each of the transmitter coils is placed in a car or other mobile platform. (The size of the coils is important, because coils of the same size transfer energy more efficiently.)

|Selected forecasts of US PEV sales with barriers to fleet penetration from limited residential charging infrastructure. Traut et al. Click to enlarge.|
An analysis by researchers at Carnegie Mellon University of parking and charging availability for electric vehicles in the US has concluded that limited availability of dedicated residential parking—and hence charging opportunities—is a significant barrier to mainstream electric vehicle adoption. The study, which was funded in part by grants from the National Science Foundation, CMU’s Steinbrenner Institute for Environmental Education and Research, General Motors, Ford and Toyota, is to appear in the journal Transportation Research (Part D).
The team, led by Professor Jeremy Michalek, assessed existing and potential charging infrastructure for plug-in vehicles in US households using data from the American Housing Survey and the Residential Energy Consumption Survey. The team found that while approximately 79% households have off-street parking for at least some of their vehicles, only an estimated 56% of vehicles have a dedicated off-street parking space—and only 47% at an owned residence. Only approximately 22% vehicles currently have access to a dedicated home parking space within reach of an outlet sufficient to recharge a small plug-in vehicle battery pack overnight.
Toyota, Nissan, Honda and Mitsubishi to provide financial assistance for EV charging infrastructure in Japan
Toyota Motor Corporation, Nissan Motor Co., Ltd., Honda Motor Co., Ltd., and Mitsubishi Motors Corporation have agreed on the details of specific financial assistance they will provide to installers of charging stations for electric vehicles (PHVs, PHEVs, and EVs). This announcement follows an agreement the four companies announced in July jointly to promote the construction of a user-friendly network of charging infrastructures. (Earlier post.)
In order for electric vehicles to become widely adopted, the partners point out, it is imperative that charging infrastructure be made widely available as quickly as possible. By assisting installers with the part of their costs not covered by government subsidies, the four companies intend to promote wider availability of chargers to make electric vehicle use more convenient.
GFEI report suggests $2T savings from fuel economy improvements in ICE vehicles through 2025 can help fund long-term transition to plug-ins
November 08, 2013
Fuel economy improvements from conventional internal combustion engine cars can save an estimated $2 trillion in fuel costs through 2025—and more in years after—according to a new working paper published by the Global Fuel Economy Initiative (GFEI) prepared by Dr. Lew Fulton, Co-Director, NextSTEPS Program at the Institute of Transportation Studies, University of California at Davis.
The GFEI, a partnership of international agencies and top energy policy experts, suggests that these cost savings could in part be used to help offset the costs of developing a global market for electric vehicles over this time frame, since the savings are estimated to be at least four times bigger than these costs.
DOE Inspector General criticizes agency’s handling of disclosures over Ecotality awards
The US Department of Energy’s (DOE’s) Office of Inspector General (OIG) has issued a report concluding that DOE “had not fully disclosed known concerns regarding Ecotality’s ability to meet its EV project obligations” to the Office of Inspector General prior to completion of an earlier audit, and thus prior to Ecotality’s bankruptcy filing in September. (Earlier post.)
The OIG concluded that DOE had not provided information that raised questions about Ecotality’s ability to meet its project goals, including completing planned EV charger installations and the collection of EV usage data—even though the data had a “readily apparent” connection to the OIG audit then underway.

CARB draft of updated AB 32 Scoping Plan for climate change actions post-2020; pushing for greater transportation reductions
October 02, 2013
The California Air Resources Board (ARB) has released the public discussion draft of the required update to the AB 32 Scoping Plan. (Earlier post.) The Scoping Plan describes the comprehensive range of efforts California must take to reduce greenhouse gas emissions to 1990 levels by 2020 and meet the state’s long-term goals to combat climate change.
AB 32 requires the Scoping Plan to be updated every five years. The original Plan, first released in 2008, was developed on the principle that a balanced mix of strategies is the best way to cut emissions and grow California’s economy in a clean and sustainable direction. This draft update continues with that approach and focuses on three questions:

One way or another, Fisker Automotive may soon be off the market
September 23, 2013
by Keith Patterson
Two German investors, Ingo Voigt and Fritz Nol, announced their intent to buy Fisker Automotive, the failing plug-in hybrid car company, on 11 September. The team submitted a detailed offer to the US Department of Energy (DOE) along with a letter of intent for restructuring Fisker.
The purchase funds for Fisker would in theory go directly to the DOE since the government agency loaned the auto company a large sum of money before it stopped production more than a year ago. Though the Voight/Nol offer amount has not yet been made public, many predict the company will sell for $25 million to $50 million. However, subsequent to the Voight/Nol offer, DOE announced it would auction off the remainder of Fisker’s loan obligation, “after exhausting any realistic possibility for a sale that might have protected our entire investment.” [See sidebar.]

Georgia Tech study suggests unlinking EVs from CAFE and coordinating with power sector for low-cost benefits
September 08, 2013
A team from Georgia Tech suggests, based on their modeling of electric vehicle (EV) adoption scenarios in each of six regions of the Eastern Interconnection (containing 70% of the US population), that coordinating EV adoption with the adoption of controlled EV charging, unlinking EVs from consideration in the CAFE fuel economy regulations; and implementing renewable electricity standards would deliver low-cost reductions in emissions and gasoline usage. (For the study, they define EVs as including both battery-electric (BEV) and plug-in hybrid electric (PHEV) vehicles.
Only in the case of high EV market share and a high renewable electricity standard (RES) do EVs make a material contribution to greenhouse gas (GHG) reductions, they found. However, managed EV adoption can reduce the cost of achieving GHG reductions through a RES, they concluded in their paper published in the ACS journal Environmental Science & Technology.

A report from the JRC on research, development and demonstration (RD&D) projects on electric drive vehicles (not including fuel cell vehicles) in the EU finds that increased exchange of information and more coordination between projects would result in a better leverage of the investments—at this point, some €1.9 billion (US$2.5 billion), 65% from public funding. The JRC (Joint Research Centre) is the European Commission’s (EC’s) in-house science service.
The report is the third in a series that deals with aspects of electromobility in Europe. Its goal was to collect the information on all on-going or recently concluded RD&D projects on electric and plug-in hybrid electric vehicles, which received EU or national public funding with a budget of more than €1 million (US$1.3 million), in order to assess which of the electric drive vehicles (EDV) challenges are addressed by these projects and to identify potential gaps in the RD&D landscape in Europe.
Chevrolet Spark EV: speedy, smooth and quiet; the importance of motor control
July 19, 2013
|The Spark EV. Click to enlarge.|
Chevrolet is hosting a series of media drives this week for the production version of its new Spark EV (earlier post). Featuring a GM-developed 105 kW electric motor that pushes out 400 lb-ft (542 N·m) of torque and a 21 kWh pack that supports an estimated 82-mile (132 km) range, the Spark EV is a speedy (0-60 mph in 7.6 seconds); efficient (combined city/highway 119 MPGe); affordable (as low as $17,495 in California net after Federal and state rebates); fun-to-drive electric vehicle targeted for the urban environment.
There are multiple interesting aspects to the vehicle, including GM’s rationale for offering fast charging as an option (it’s not to go across country), but one of the most manifest when driving the car (aside from the “Wheee!” of those 400 lb-ft in action) is how smooth and quiet the drive is. Much of this derives from the efforts GM has put over the years into motor control and active damping for hybrids and EVs.

Bosch, PSA Peugeot Citroën and partners recently presented the first two Optimal Energy Consumption and Recovery solution (OpEneR) prototypes. OpEneR is a European research project under the Seventh Framework Programme designed to increase the range of future hybrid and electric vehicles by optimizing energy management.
Launched in 2011, OpEneR is developing new driving strategies and driver assistance systems that significantly increase the efficiency, driving range, and safety of electric vehicles without increasing battery size—and thus also by limiting battery price and charging time. This is achieved by merging data from on-board and off-board sources. A particular focus lies on an optimal cooperation between the electric drivetrain and the regenerative braking system, supported by data from radar, video, satellite navigation, car-to-infrastructure and car-to-car systems.

|The OnStar-TimberRock project. Click to enlarge.|
GM’s OnStar announced a project with TimberRock Energy Solutions, Inc. that uses aggregation software and solar charging canopies with integrated storage to manage the flow of solar power to benefit the electric grid. It will be the first “real-world” use of OnStar’s Smart Grid solutions. (Earlier post.)
TimberRock will monitor the output of its solar charging stations, how much stored energy is available and when it can sell energy back to the grid to help meet peak demand. To help balance this system, TimberRock will then manage its fleet of four Chevrolet Volts to help regulate energy flow. This practice is known as market-based regulation.

The increasing demand for and investment in hybrid propulsion systems has brought with it focused study of the supervisory control (i.e., energy management) problem along with a range of different approaches (e.g., rule-based control, dynamic programming, equivalent consumption minimization strategies, and so on) to tackle the problem.
In a paper presented at the recent 2013 American Control Conference (ACC) in Washington, Dr. Andreas Malikopoulos from Oak Ridge National Laboratory (ORNL) described an approach to the problem of optimizing online the supervisory control in a series hybrid configuration by modeling its operation as a controlled Markov chain using an average cost (in this case, fuel consumption) criterion to create an equilibrium control policy.

|XL1s ready to roll. Click to enlarge.|
During a media event in Wolfsburg, Germany, Volkswagen provided a medium dive into details of its two-seater XL1 Super Efficient Vehicle diesel plug-in hybrid (earlier post) as well as some driving time on local roads and highways.
The XL1 is aggressively optimized for efficiency in all areas of its design and technology—from materials (carbon fiber reinforced polymer monocoque); to powertrain (0.8L two-cylinder diesel, 20 kW electric motor and 5.5 kWh Li-ion pack with efficiency-optimized control and brake regeneration strategies); to lightweighting (little baffling to shield the driver from engine, chassis and road noises); to aerodynamics (with a Cd of 0.189, the XL1 bests the only other production vehicle that has come close, the GM EV1’s 0.19; the original Honda Insight hybrid had a Cd of 0.25). It reflects, the Volkswagen team members said, an effort by the company to deliver the most efficient vehicle they could—but one that could still be series-produced, homologated and sold—with current technologies.

June 18, 2013
|Powertrain technologies outlook up to 2020. Click to enlarge.|
At the company’s 61st Automotive Press Briefing in Boxberg, Germany, Bosch senior executives outlined the company’s view on the general future of automotive technology—“efficient and increasingly electrical”, and provided a thumbnail of the way they see—and thus are developing products for—sector-specific technology trends.
In general, said Dr. Bernd Bohr, Chairman of the Bosch Automotive Group, the pace of development continues to pick up, in the form of powertrain electrification and the automation of driving. Bosch does not believe there is just one powertrain solution for the future; most of the cars on the world’s roads are still running on diesel and gasoline, and things will stay that way for the rest of the decade, Bohr noted. However, “slowly but surely”, the number of alternatives is growing.

Combined cycle fuel consumption is estimated at 1.6 l/100 km (147 mpg US), with 36 g/km CO2; all-electric range is 31 miles (50 km). With a fully charged battery and a full 40-liter (10.6 gallons US) gasoline tank, its total range is 507 miles (816 km).
EPRI: lifetime cost of ownership of plug-ins is roughly comparable with conventional vehicles
June 11, 2013
Consumers who purchase an electric vehicle will find that lifetime costs to own the vehicle are competitive with conventional and hybrid vehicles, according to an analysis conducted by the Electric Power Research Institute (EPRI). The study is based on pricing for the automotive products for the 2013 model year.
The baseline analysis relies on a cost-of-ownership model that examines only current vehicles; current fuel prices; and a relatively conservative set of customer values. In particular, the report analyzes the Chevrolet Volt and Nissan LEAF in comparison with a limited set of current conventional and hybrid vehicles. The EPRI analysis focused on the LEAF and Volt because the plug-in vehicles have been on the market the longest, have generated the greatest sales volume and provide data on real-world performance.
Navigant forecasts hybrids to account for almost 4% of global LDV sales by 2020, plug-ins 3%
|Annual light duty electric vehicle sales by drivetrain, world markets: 2013-2020. Source: Navigant Research. Click to enlarge.|
In its latest forecast for hybrid and plug-in electric vehicle sales, Navigant Research expects that hybrid electric vehicles (HEVs), which today account for about 2% of global light duty vehicle sales, will grow to almost 4% of global LDV sales by 2020.
The company also expects, despite the challenges of new technology, that plug-in electric vehicles will grow rapidly in many regions as a result of rising fuel prices, falling PEV prices, and increasing availability of PEV models. The result is a PEV market that will reach 3 million vehicles sold in 2020, representing 3% of the global light-duty vehicle market.
CCST report: an integral role for next-gen biofuels in meeting California GHG targets requires advanced biofuels and demand reduction
Next-generation biofuels can reduce greenhouse gas emissions of transportation to meet California’s target greenhouse gas (GHG) reduction goal, but deep replacement of fossil fuels through implementation of low-carbon lignocellulosic ethanol and advanced biomass derived hydrocarbons (drop-in biofuels) and reduction in demand is required, according to a new report from the California Council on Science and Technology (CCST).
The study, “California Energy Future: the Potential for Biofuels,” co-authored by Energy Biosciences Institute (EBI) scientists Heather Youngs and Chris Somerville, is the seventh and final report in its California’s Energy Future (CEF) project. The CEF project seeks ways the State could meet the mandated reductions of greenhouse gas (GHG) emissions to 80% below 1990 levels by 2050, exploring possible energy strategies for California through in-depth examinations of different technology scenarios.
CMU study finds driving conditions have “substantial” impact on benefits of electrified vehicles; policy implications
June 10, 2013
|NHTS-Averaged Annual GHG Emissions per vehicle type by drive cycle. (Base Case). Source: Karabasoglu and Michalek. Click to enlarge.|
A new analysis by Orkun Karabasoglu and Jeremy Michalek of the Carnegie Mellon Vehicle Electrification Group at Carnegie Mellon University found that driving conditions affect the economic and environmental benefits of electrified vehicles “substantially”.
As a result, they suggested, vehicle window stickers, fuel economy standards, and life cycle studies using average lab-test vehicle efficiency estimates are incomplete. Driver heterogeneity matters, they found, and efforts to encourage adoption of hybrid and plug-in vehicles will have greater impact if targeted to urban drivers vs. highway drivers. Further, electrified vehicles perform better on some drive cycles than others, so non-representative tests can bias consumer perception and regulation of alternative technologies. Their study is published in the journal Energy Policy.

The index compares the development of e-mobility in seven leading car-manufacturing nations (Germany, France, Italy, US, Japan, China and South Korea) on the basis of three parameters: technology, manufacturing, and market.
National Academies issues interim report on overcoming barriers to PEV deployment
The National Academies has issued a pre-publication version of an interim report on Overcoming Barriers to Electric-Vehicle Deployment. A final, comprehensive report will be published in late summer 2014.
Given recognized technical, social, and economic barriers to widespread adoption of plug-in electric vehicles (plug-in hybrid and battery-electric vehicles), Congress had asked the Department of Energy (DOE) to commission a study by the National Academies to address market barriers that are slowing the purchase of electric vehicles and hindering the deployment of supporting infrastructure. As a result, the National Research Council (NRC)—a part of the National Academies—appointed the Committee on Overcoming Barriers to Electric-Vehicle Deployment.

Chalmers team developing new high-power integrated motor and battery charger; “rotating transformer”
April 30, 2013
Researchers at Chalmers University of Technology in Sweden have developed a new type of high-power integrated motor drive and battery charger for electric vehicles. Compared to today’s electric vehicle chargers, the new system could shorten the charging time from eight to two hours, and to reduce the cost by around $2,000, according to the developers.
Dr. Saeid Haghbin at Chalmers proposed the system which uses the components in the traction circuit—such as the electric motor and the inverter—in the charger circuit to reduce the size, weight and price of the on-board charger. In essence, the proposed system uses the motor as a grid-connected generator with extra terminals.
