Daimler wraps up eMERGE EV 2-year fleet trial, launches larger eMERGE2 with EVs and PHEVs
July 31, 2015
Daimler reports that the two-year eMERGE real-world trial of 146 smart fortwo electric drive vehicles has been completed. Those taking part in the project were private and business customers in Berlin, Potsdam and North Rhine-Westphalia. The lowest average energy consumption per vehicle over one year was 10.4 kWh/100 km, while the longest single-charge range was 161 kilometers (100 miles). The smart fortwo electric drive is certified with a consumption of 16.3 kWh/100 km and a range of 145 kilometers (90 miles).
eMERGE is being followed directly by eMERGE2, which will see up to 200 cars being used in the model regions of Berlin/Potsdam, Stuttgart, Rhine-Ruhr and Rhine-Main. The vehicle fleet will include the battery electric B 250 e and plug-in hybrids from Mercedes-Benz. The different technology and vehicle segments suggest different use cases than the smart fortwo electric drive.

July 29, 2015
BRUSA Elektronik AG, an automotive Tier 1 power electronics supplier, has licensed Qualcomm Incorporated’s Halo (earlier post) patented inventions to commercialize Wireless Electric Vehicle Charging (WEVC) systems for Plug-In Hybrid and Electric Vehicles (EVs). Under the terms of the agreement, Qualcomm granted to BRUSA a royalty-bearing patent license to develop, make and supply WEVC systems for certain automobile manufacturers.
BRUSA, which has been working on its own Inductive Charging System (ICS) for wireless power transfer (WPT), developed its own coil geometry: FRAME technology. The coil is rectangular and enables inductive charging of electric vehicles with the integration of power electronics both in the vehicle and in the base plate, enabling a one-box system.
BMW i novel drive unit swing arm powers HNF eBike
July 27, 2015
In addition to developing its own innovative premium vehicles and technologies with a focus on sustainability, BMW i also serves within the BMW Group as an incubator for innovation reaching beyond the brand’s vehicles.
As one example, a drive unit swing arm, now entering production at the HNF eBike factory after development to series maturity in collaboration with BMW Research and Technology, originated from the first stage of BMW i market research and the early concept phase. As there was no longer any immediate use for the patent at BMW i, the company released it for external use.
BRUSA offering new high-efficiency motor/gearbox combination for electric commercial vehicles
BRUSA Elektronik AG is offering its Planetary Traction Drive DTSP1—a fully integrated electric vehicle drivetrain combining motor and gearbox—with its higher power HSM1-10.18.22 Hybrid Synchronous Motor, offering 220 kW (295 hp) maximum power (145 kW/194 hp continuous) and up to 460 N·m (339 b-ft) peak torque (270 N·m/199 lb-ft continuous). With this configuration, BRUSA is targeting light commercial vehicles, vans or sports cars.
The compact design of the transmission in combination with the powerful motor results in a highly efficient power set. The DTSP1 unit can be used as an axle or four-wheel drivetrain set. By using the differential on the axles, powerful yet weight-optimized drives can be realized. With the adjustment of the axle differential every application can be achieved with the right ratio.
Researchers show use of MFRE can at least double wireless power transfer efficiency; more efficient than metamaterials
July 23, 2015
Researchers at North Carolina State University and Carnegie Mellon University have shown that passing wireless power transfer through a magnetic resonance field enhancer (MR-FE)—which could be as simple as a copper loop—can at least double transfer efficiency as compared to transferring through air alone. MR-FE use could potentially boost transfer efficiency by as much as 5,000% in some systems, the researchers said.
Wireless power transfer works via magnetic coupling or inductive coupling, and can achieve very high efficiency when the distances between the transmitter and receiver are small—less than a few centimeters. In such a case, the transmitter and receiver are strongly coupled, with a high coupling coefficient (usually greater that 0.9). As distance increases, the strength of the coupling decreases. Enhancing wireless power transfer efficiency over greater distances—to support, for example, the wireless charging of electric vehicles—has thus been a major goal of many research groups.
DLR and Wuppertal publish comprehensive global analysis of e-mobility technologies, outlook and lifecycle assessments

SFU researchers find promise for plug-in vehicles in Canada, but need for increased supply and policy support
July 16, 2015
New work by a team at Simon Fraser University (SFU) in Canada has found that more than one-third of Canadian buyers want a plug-in vehicle (PEV), with the majority of those (89—93%) wanting a plug-in hybrid rather than a pure electric vehicle. However, less than 1% of vehicle sales in Canada are electric because of low consumer awareness and limited vehicle choice.
With the current supply of PEVs in Canada (7 models), the future PEV new market share is not likely to exceed 4—5% by 2030, according to the report; increasing supply (to 56 models) could increase market share to over 20% by 2030.

ELIX Wireless rolled out its initial product offering, the E1K Wireless Charging System, to customers in early 2015. The E10K Wireless Charging System is now commercially available to customers and partners.
Typical wireless charging solutions available in the market today are based on inductive technologies and deliver up to 7.7kW. To meet the demand for a faster, higher power wireless charging solution that can operate under extreme environmental conditions, ELIX Wireless developed the E10K Wireless Charging System. E10K “building blocks” can be combined together to create even higher power systems.
EU project V-Charge makes final demonstration of automated valet-parking and inductive charging system
The V-Charge (Valet Charge) research project, a four-year, €5.63-million (US$6.21-million) effort partly funded through the EU’s Seventh Framework Programme for Research to develop systems for automated valet-parking and inductive charging for electric vehicles, has made the final presentation of its work in a demonstration at the Excellence Parking Garage at Amsterdam airport.
The fully automated parking system relieves drivers of the tiresome and time-consuming task of finding a parking spot. The vehicle not only automatically looks for an empty parking space, but finds an empty space with charging infrastructure and inductively charges its battery. Once the charging process is finished, it automatically frees up the charging bay for another electric vehicle and looks for a conventional parking space.

The wireless charging systems are capable of transferring their high power without need for precise alignment between the charger and the vehicle.
Berkeley Lab analysis finds autonomous electric taxis could greatly reduce US LDV GHG emissions
July 06, 2015
Researchers at Lawrence Berkeley National Laboratory (Berkeley Lab) have found that the per-mile greenhouse gas emissions of an electric autonomous taxi in 2030 would be 63-82% lower than a projected 2030 hybrid vehicle driven as a privately owned car and 90% lower than a 2014 gasoline-powered private vehicle. Their paper appears in the journal Nature Climate Change.
The autonomous vehicles (AVs) gain their through three synergistic effects, the researchers found: (1) future decreases in electricity GHG emissions intensity; (2) smaller vehicle sizes resulting from trip-specific autonomous taxi deployment (i.e., “right-sizing,” where the size of the taxi deployed is tailored to each trip’s occupancy needs); and (3) higher annual vehicle-miles travelled (VMT), increasing high-efficiency (especially battery-electric) vehicle cost-effectiveness.
BMW and SCHERM put 40t battery-electric truck into service for material transport in 1-year pilot
The BMW Group and the SCHERM group have put a 40-ton electric truck for material transport into service on public roads in a one-year pilot. The truck, a Terberg YT202-EV electric tractor, has successfully completed its first test drives. The truck will travel a 2km route (1.2 miles) eight times a day between the SCHERM group logistics center and the BMW Group plant in Munich, transporting different vehicle components such as shock absorbers, springs and steering systems.
The truck battery takes three to four hours to charge. When fully charged, the vehicle has a range of up to 100 kilometers (62 miles). Thus, the electric truck can theoretically complete a full production day without any additional recharging.
Navigant forecasts global annual sales of LDVs of 122.6M by 2035, up 38% from 2015
In a new report, Navigant Research forecasts global annual sales of light duty vehicles will reach 122.6 million by 2035, up 38% from a projected 88.8 million this year, representing a compound annual growth rate (CAGR) of 1.6%. Navigant Research expects the number of LDVs in use on roads worldwide to grow by 57.1% from 2015 to 2035 to almost 1.9 billion units.
Navigant expects sales of conventional internal combustion engine (ICE) vehicles will fall significantly over the forecast period, experiencing a CAGR of -6.6%. As a result, the share of vehicles in use that are conventional ICE vehicles will fall from more than 91% in 2015 to under 40% by 2035. Navigant expects ICE vehicles will be replaced by start-stop vehicles (SSVs), which will grow from representing more than 4% of vehicles in use in 2015 to nearly 49% in 2035. Hybrids (HEVs) are expected to account for nearly 3%, while PHEVs (plug-in hybrids), BEVs (battery-electric vehicles), NGVs (natural gas vehicles), PAGVs (propane autogas vehicles), and FCV (fuel cell vehicles) s together are projected to add up to more than 9% of the LDVs in use in 2035.
China’s ZTE pushing ahead with high-power wireless charging vehicle test deployment
ZTE Corporation, China’s largest listed telecommunications equipment company, is developing high-power wireless charging systems and services for electric vehicles, with a focus on public charging infrastructure. At a China-US workshop on electric vehicle standardization held in June (earlier post), Academus Tian, VP of ZTE New Energy Vehicle Co., presented an overview of ZTE’s efforts in wireless power transfer (WPT).
Tian said that ZTE’s inductive charging WPT module has a potential capacity of up to 30 kW, with a gap of 20 cm and efficiency of up to 90%. The footprint of the device is less than 1 m2; frequency is 85 kHz. ZTE, which has aggressively partnered with a number of passenger and commercial vehicles makers over the past few years, has recently launched a series of commercial vehicle (bus) WPT trials.
Study: even with high LDV electrification, low-carbon biofuels will be necessary to meet 80% GHG reduction target; “daunting” policy implications
July 03, 2015
A study by researchers from the University of Wisconsin-Madison and a Michigan State University colleague has concluded that even with a relatively high rate of electrification of the US light-duty fleet (40% of vehicle miles traveled and 26% by fuel), an 80% reduction in greenhouse gases by 2050 relative to 1990 can only be achieved with significant quantities of low-carbon liquid fuel. The paper is published in the ACS journal Environmental Science & Technology.
For the study, the researchers benchmarked 27 scenarios against a 50% petroleum-reduction target and an 80% GHG-reduction target. They found that with high rates of electrification (40% of miles traveled) the petroleum-reduction benchmark could be satisfied, even with high travel demand growth. The same highly electrified scenarios, however, could not satisfy 80% GHG-reduction targets, even assuming 80% decarbonized electricity and no growth in travel demand.
Researchers find Nissan LEAF creates less CO2 than Toyota Prius hybrid in west US and Texas, but more in N. Midwest
July 01, 2015
Regionally specific lifecycle CO2 emissions per mile traveled for plug-in hybrid electric vehicles (PHEVs) and battery electric vehicles (BEVs) in the US can vary widely based on grid emission factors (i.e., the “carbon footprint” of electricity production and use), according to a new study by researchers at Carnegie Mellon University. Under some conditions, the battery electric Nissan LEAF can produce higher emissions than a Toyota Prius hybrid. The paper is published in the ACS journal Environmental Science & Technology.
The team characterized the vehicle emissions across the United States under alternative assumptions for regional electricity emission factors, regional boundaries, and charging schemes. Among the findings were that:
CMU policy briefs outline benefits and potential for adoption of electrified vehicles in the US
Researchers at Carnegie Mellon University (CMU) have published two new policy briefs, along with accompanying videos, about the benefits of electrified vehicles and the potential for their adoption in the US. The briefs condense the findings of a number of recent papers coming out of the CMU group led by Professor Jeremy Michalek.
The first—“Electric Vehicle Benefits and Costs in the United States”—shows that the benefits of vehicle electrification vary based on vehicle type; driving style; climate; how supplying electricity is generated; and time of charge. To achieve the best outcomes, the brief suggests, plug-in vehicle adoption should typically be focused on HEVs and PHEVs by city drivers in mild-climate regions with a clean electricity grid, such as San Francisco or Los Angeles. Further, drivers should not be encouraged to charge at night in coal-heavy regions.
BMW Group and NTU Singapore launch US$965K electromobility research program; Electromobility in Asia and Smart Materials

Both parties will be injecting a combined S$1.3 million (US$965,000) to drive the new research projects, on top of the initial S$5.5 million (US$4.1 million) funding allocated to the joint lab in 2013. The new research program will focus on two new areas, Electromobility in Asia and also Smart Materials. This is in addition to the original three research topics on which the joint lab is already working: Advanced Battery; Driver Enhancement; and Intelligent Mobility.
DOE to award $20M to projects to recover rare earth elements from coal and coal byproducts
June 29, 2015
The US Department of Energy (DOE) has issued a funding opportunity (DE-FOA-0001202) that will award an estimated $20 million to projects quickly to develop bench scale and pilot scale projects for recovering Rare Earth Elements (REE)—a set of seventeen chemical elements in the periodic table and key components of electronics and renewable energy technologies—from coal and coal byproducts.
The DOE has begun investigating the economic feasibility of recovery of REEs from domestic United States coal and coal byproducts. n FY14, DOE’s National Energy Technology Laboratory (NETL) conducted a preliminary, short-term, baseline field evaluation of coal and coal by-products as potential domestic resources of REEs. NETL has characterized a number of REE-bearing samples of coal and coal related materials, and posted the associated results and reports here.
Opinion: Why Buffett Bet A Billion On Solar: Miles Per Acre Per Year
by Henry Hewitt for Oilprice.com
During the late innings of the ICE-age (as in the Internal Combustion Engine age) it has become clear that feeding gasoline and diesel to the next billion new cars is not going to be easy, or cheap. In China alone, 500 million new vehicles can be expected to jam the roads between now and 2030.
That may sound far-fetched, but considering annual sales have already made it to 25 million units per year (vs. around 17 million in the US—China became the top market in 2009), it only requires a 4 percent growth rate to reach that target in fifteen years.
California ARB approves $373M funding plan for advanced vehicle technologies in FY2015-2016; up from $150M last year

LowCVP: 5 Ps for influencing uptake of low emission vehicles at local level
The UK’s Low Carbon Vehicle Partnership has launched a Good Practice Guide for Local Measures to Encourage the Uptake of Low Emission Vehicles. A key recommendation is that policy measures implemented at the local level should be consistent with each other, that common definitions and vocabulary for low emission vehicles should be established. The Good Practice Guide for Local Measures to Encourage the Uptake of Low Emission Vehicles was prepared for the LowCVP by Urban Foresight.
Released to coincide with the LowCVP’s 2015 Annual Conference which features a discussion on mobility in future cities, the LowCVP has identified five ‘P’s from the Guide—levers that local authorities can most effectively use to influence low emission vehicle uptake at the local level:

June 08, 2015
|TCF, the manager of the Garcia River Forest Project, would like to enable its increasing number of redwood trees to reach the 1,000-year-old status of some of their neighbors, like this one. Click to enlarge.|
In 2014, Volkswagen of America announced that starting with the launch of the zero-tailpipe emissions battery-electric 2015 e-Golf (earlier post), it would invest in projects to offset the carbon emissions created from the e-Golf on a full lifecycle basis: production, distribution and up to approximately 36,000 miles (57,936 km) of driving.
Last week, Volkswagen provided a close-up look at one of the projects in which it is investing: the Garcia River Conservation-Based Forest Management Project, located in Mendocino County, California. This project, to which Volkswagen contributes along with companies such as UPS, repairs and preserves a ~24,000-acre native redwood forest, increasing carbon sequestration and storage, while also helping to restore the natural wildlife habitat. Emission reductions produced by the project are verified by an approved third party and registered with the Climate Action Reserve (Project ID CAR102).

US$7.5M JOSPEL project to develop energy efficient climate control for EVs; leveraging Joule and Peltier effects
June 03, 2015
A trans-European collaboration aims to develop a novel energy efficient climate control system to help reduce the energy used for passenger comfort in electric vehicles by at least 50%. Even in today’s modern electric vehicles, a lot of energy is wasted on heating or cooling, in turn limiting the already relatively short range by further draining the battery capacity.
The aim of the €6.7-million (US$7.5-million) JOSPEL project is to develop an efficient, electrical climate control system using an integrated approach that combines the application of the Joule and Peltier effects; efficient insulation of the vehicle interior; energy recovery from heat zones; increased battery life as a side effect of thermal management; reduced battery energy consumption via the integration of Peltier cooling; innovative automated and eco-driving strategies; and the electronic control of power flows.

Bosch retrofits a pair of Tesla Model S EVs for automated driving testing
May 21, 2015
Bosch has retrofitted two Model S Teslas for automated driving; the vehicles join the Bosch test fleet. The two Teslas can now autonomously drive from on-ramp to off-ramp without the driver needing to monitor them constantly. Dr. Dirk Hoheisel, member of the Bosch board of management, said that Bosch opted for two all-electric Model S vehicles because they combine two automotive industry trends: electrification and automation.
Fifty new Bosch components were installed in each car, including a stereo video camera (SVC), which the car uses to recognize lanes, traffic signs, and clear spaces. The Bosch says that its SVC is the smallest stereo camera system for automotive applications currently available in the market; the compact design makes it easy to integrate into vehicles. In addition to the camera, 1,300 meters of cable were laid in each car and fixed in place with 400 cable ties.
Lux Research: Li-ion battery costs to drop to as low as $172/kWh by 2025; big boost for EVs in mid- to late 2020s
May 19, 2015
The electric vehicle opportunity is set to expand, as leading battery developers such as Panasonic drive down prices of Li-ion battery packs by 35% to $172/kWh in 2025, according to a new report, “Crossing the Line: Li-ion Battery Cost Reduction and Its Effect on Vehicles and Stationary Storage,” by Lux Research. However, only the best-in-class players will achieve that cost threshold, while others lag at $229/kWh.
The estimate is based on a new bottom-up cost model built by Lux Research in an industry known for being highly secretive about its costs. The model accounts for differences in battery chemistry, form factor, production scale, location and other nuances.
Faradion demonstrates proof-of-concept sodium-ion electric bike
May 15, 2015
|E-bike powered by Faradion prototype Na-ion battery pack. For the proof-of-concept, the cells were manufactured to be larger than necessary to avoid unnecessary costs and lengthy manufacturing processes at this early stage. Click to enlarge.|
British battery R&D company Faradion has demonstrated a proof-of-concept electric bike powered by sodium-ion batteries at the headquarters of Williams Advanced Engineering, which collaborated in the development of the bike. Oxford University was also a partner. Although lithium-ion batteries are currently the predominant battery technology in electric and hybrid vehicles, as well as other energy storage applications, sodium-ion could offer significant cost, safety and sustainability benefits.
Sodium-ion intercalation batteries—i.e., batteries using the same process of ion insertion and removal as in Li-ion batteries—have been discussed in the literature for some time. (e.g., Earlier post.) Using sodium instead of lithium in a battery is attractive because it could potentially be much less expensive (~30% less) and safer, and it would be more environmentally benign. However, developing efficient Na+ intercalation compounds is a challenge because sodium ions are much larger than lithium ions—about 70% larger in radius. Thus, insertion/deinsertion of sodium ions in a host material is much more difficult than that of lithium ions.

First 18-meter electric bus in China powered by TM4 SUMO HD powertrain with external rotor motor technology
China’s first 18-meter battery electric bus has been put into service in Beijing. The Foton AUV 18-meter Harmony City BJ6180 is powered by a TM4 SUMO HD electric powertrain with a maximum torque of 3,500 N·m (2,581 lb-ft), 1600 N·m (1,180 lb-ft) continuous.
The SUMO HD is designed to interface with standard rear differentials without the need for an intermediate gearbox. Its direct drive / gearless approach makes it a good match for high-duty platform and commercial vehicle applications. The system features TM4’s external rotor motor technology (in which the rotor rotates on the outside of the stator). The external rotor motor technology delivers higher power density, high torque density, and increased long-term reliability than a similar motor with an internal rotor, according to TM4.
OEMs shifting towards onboard chargers > 6 kW for EVs; lower output chargers to remain dominant through 2020
May 05, 2015
Most battery and plug-in hybrid electric vehicle (PHEV) manufacturers in Europe and the US have been adopting onboard chargers with a power output between 3 to 3.7 kilowatts (kW). Now, EV manufacturers are moving towards onboard chargers with a power output greater than 6.6 kW to reduce charging time.
While high-end PHEVs are contributing to this trend, lower-end models in this segment are still using 3.7 kW onboard chargers. Consequently, onboard chargers with power ratings between 3 to 3.7 kW are expected to remain dominant, accounting for 62% of sales even in 2020, according to new analysis from Frost & Sullivan.
Volkswagen Group to offer more than 20 electric vehicle models in China “in near future”
The Volkswagen Group plans to offer more than 20 electric vehicle models—from small cars to large sedans and SUVs, plug-in hybrids and battery-electric vehicles—to Chinese customers “in the near future,” according to Prof. Dr. Jochem Heizmann, Member of the Group Board of Management with responsibility for China, in a special essay published in the Environment section of the company’s newly released sustainability report.
The Chinese government has set guidelines to reduce CO2 emissions in China to a fleet fuel consumption of 5 l/100 km (47 mpg US) as measured on the New European Driving Cycle (NEDC) by 2020. The expected fleet average this year is 6.9 l/100 km (34 mpg US). Thus, the government is requiring an overall reduction of about 28%, or 6.2% per year, between 2015 and 2020. Meeting this target will be even more challenging than meeting the 95 g/km target for 2020 set by the European Union, writes Dr. Heizmann, explaining:
Wrightspeed unveils new turbine range extender for medium- and heavy-duty electric powertrains; 30% more efficient than current microturbine generators
May 04, 2015
Wrightspeed Inc., a developer of range-extended electric vehicle powertrains for medium- and heavy-duty vehicles (earlier post), has unveiled the Fulcrum, a new proprietary turbine generator for use in its Route family of electric powertrains (Route for Class 3-6, Route HD for Class 7-8). The new 80 kW Fulcrum is a radial inflow, axial turbine, intercooled and recuperated. Fulcrum is a single shaft machine, the generator runs at turbine speed (~100,000 rpm). Weighing in at 250 lbs (113.4 kg), the Fulcrum is approximately 1/10th the weight of its piston generator counterparts and it is designed to have a 10,000-hour lifetime.
The Route extended range electric powertrains incorporate a range-extending genset designed to recharge the high-power battery pack (currently from A123 Systems) and Wrightspeed’s own geared traction drive (GTD) (earlier post). Wrightspeed, founded by Ian Wright, one of the original co-founders of Tesla Motors, has used a 65 kW Capstone microturbine in earlier Route powertrains. The 65 kW Capstone unit weighs 300 lbs (136.1 kg), for a power-to-weight ratio of 478 W/kg; by comparison, Wrightspeed’s new Fulcrum microturbine offers a power-to-weight ratio of 750 W/kg. With Fulcrum, on which the company has been working for about 3 years, Wrightspeed now owns 100% of the Intellectual Property of its powertrain products.
HRL Labs video demonstrates principle of thermal battery based on advanced metal hydrides for EV heating and cooling
April 30, 2015
In 2011, the Advanced Research Projects Agency - Energy (ARPA-E) awarded $2.7 million to a team comprising researchers from the University of Utah, HRL Laboratories and GM Global R&D for a project to develop a new generation of high-density thermal battery based on advanced metal hydrides. (Earlier post.) The goal of the project, part of ARPA-E’s HEATS (High Energy Advanced Thermal Storage) portfolio, was to develop a compact thermal battery for climate control in electric vehicles. Such a thermal battery would provide heating and cooling without draining the electric battery, in effect, extending the driving range of EVs per electric charge.
As described in a paper in press in the Journal of Alloys and Compounds, the developed system uses a pair of thermodynamically matched metal hydrides as energy storage media: (1) catalyzed MgH2 as the high temperature hydride material, due to its high energy density and enhanced kinetics; and (2) TiV0.62Mn1.5 alloy as the matching low temperature hydride. HRL has now released a video demonstrating the principle behind the work on thermal battery technology.
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.

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.

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.
New Fairchild automotive SuperFET II MOSFETs and HV Rectifiers for power electronics in electrified vehicles
Fairchild, a leading global supplier of high-performance power semiconductor solutions, has introduced the automotive-qualified SuperFET II MOSFET and High Voltage Rectifier product families, both of which enable cleaner and smarter vehicles overall and are suited for increasing the power ratings of onboard chargers and DC-to-DC converters used in hybrid, plug-in hybrid and all-electric vehicles.

With the broad portfolio of new SuperFET II MOSFETs and High Voltage Rectifiers, Fairchild is enabling manufacturers to maximize efficiency, power density and reliability of these units, which is key to reducing their size and weight and is of course in line with the environmental, economic and energy benefits inherent in electric vehicle development,” said Fabio Necco, Director, Hybrid and Electric Vehicle Segment at Fairchild.
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.

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.

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.
