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.

July 24, 2014
The California Energy Commission gave final approval for nearly $50 million in grant awards for hydrogen refueling and electric charging construction projects recommended for funding in notices of proposed awards published in April and May.
California’s zero-emission vehicle goal is to get 1.5 million hydrogen, battery electric, and plug-in electric vehicles on the roadway by 2025. In response to this directive, the Energy Commission’s Alternative and Renewable Fuel and Vehicle Technology Program (ARFVTP) has already allocated nearly $400 million to help bolster statewide infrastructure and create a viable market for zero-emission vehicles (ZEVs), and to promote alternative fuels.
ABB and Volvo Buses partnering on fast-charging system for hybrid and electric buses
July 22, 2014
ABB and Volvo Buses are partnering to co-develop and to commercialize electric and hybrid buses with open standards-based direct current (DC) fast charging systems. The cooperation will create a city-wide standardized charging system for electric and electric hybrid buses that can charge buses quickly through an automatic roof-top connection system at bus stops or through cabled charging systems overnight.
This approach, based on internationally accepted standards (EN61851-23), enables maximum re-use of existing e-mobility technologies, thereby ensuring a rapid deployment of urban e-mobility. The first joint project will be the implementation of Volvo Electric Hybrids and ABB’s automatic e-bus chargers in the Luxembourg public transport system, where as many as 12 Volvo Electric Hybrid buses operated by Sales-Lentz will be running on existing lines by 2015.
Driving the VW e-Golf; strategy, assembly in Wolfsburg, Braunschweig battery plant
July 21, 2014
|The e-Golf. Click to enlarge.|
The e-Golf (“Das e-Auto” earlier post), the Volkswagen brand’s second series production battery-electric vehicle after the e-up!, is a key model, as it is the best and most current implementation of its strategic decision to begin providing e-mobility based on large-scale production models rather than special “small niche” cars. The Golf is core to Volkswagen; the company has sold more than 30 million units worldwide since the first introduction in 1974. The e-Golf is based on current 7th generation Golf, itself based on the strategic MQB toolkit.
Put another way, Volkswagen’s goal, based on its strategic approach, is for the e-Golf to deliver the performance and handling of a Golf which happens to have a battery-electric powertrain. Based on a second, and slightly longer, chance to drive the new e-Golf unsupervised, we think Volkswagen has succeeded splendidly in this goal; we find the e-Golf to be a nimble and quiet electric delight.

July 17, 2014
|OpEneR partners have developed driving strategies and driver assistance systems to improve the efficiency and safety of electric vehicles. Click to enlarge.|
At its final review, the European research project OpEneR (“optimal energy consumption and recovery based on a system network”) presented collaboratively developed driving strategies and driver assistance systems to improve significantly the efficiency (and hence range) and safety of electric vehicles by optimizing energy management. (Earlier post.)
In comparison to a typical sporty driver, the OpEneR operation strategies resulted in a reduced energy consumption of 27 to 36%, with the trade-off of an increase in travel time of between 8 to 21%—depending on the driver’s willingness to follow the recommendations. Approximately 5 percentage points of the energy consumption reduction were due to intelligent torque distribution between front and rear electric motors in the demonstrators, which had no influence on travel time at all.

July 11, 2014
|Silicon Carbide multiport DC-DC converter fitted to the Tata Vista EV. Click to enlarge.|
A consortium led by motorsport and technology company Prodrive has successfully run a silicon carbide-based multiport DC-DC converter in an electric car. The converter controls power flow between multiple energy sources and has been able to achieve efficiency of 98.7%, while increasing power density and reducing the size and weight of the converter when compared to silicon-based systems.
A key aspect of the converter is the use of silicon carbide devices. These operate at a much higher frequency than equivalent silicon components—at 75 kHz in the test vehicles—with a significant reduction in switching losses. This has resulted in a significant reduction in the size of the magnetic components and has enabled the converter to achieve an efficiency of 98.7%, a gravimetric power density of 10.5 kW/kg and a volumetric power density of 20 kW/liter.
Navigant forecasts MHD vehicle market to nearly double by 2035 with declining share of conventional engines; gases win out over electricity
July 07, 2014
The number of medium- and heavy-duty vehicles (MHDVs) in use worldwide will nearly double between 2014 and 2035, according to a new forecast report by Navigant Research. Navigant projects that annual MHDV sales will grow throughout the forecast period at a compound annual growth rate (CAGR) of 2.4%.

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.

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.

The Volkswagen Group’s MQB modular toolkit is one of the four main modular toolkits (modularen Baukästen) of the Group: the MQB (transverse); the MLB (longitudinal); the MSB (standard drive); and the NSF (New Small Family). The toolkits standardize many vehicle component parameters across brands and vehicle classes, while at the same time offering access to new technologies, such as alternative drive systems. The new Mark 7 Golf, which is MQB-based, offers gasoline; diesel; natural gas; plug-in hybrid (the GTE); and battery-electric (the e-Golf) versions, all of which can be manufactured bumper-to-bumper on the same assembly line. The MQB spans the A0 to C segments.

At the beginning of 2012, nearly 100,000 of the cars were on the roads worldwide. This rose year later to a total of 200,000, and then to 405,000 units earlier this year.
Tesla adding underbody triple shield system to Model S to reduce risk of battery fires caused by impacts
March 28, 2014
In an effort to reduce further the already low risk of a Model S battery fire resulting from impact with road debris, Tesla Motors is outfitting new Model S cars (as of 6 March) with an underbody triple shield system consisting first of an aluminum bar; then a titanium shield; and finally a shallow angle solid aluminum extrusion.
Tesla will also retrofit the system, free of charge, to existing Model S cars upon request or as part of a normally scheduled service, wrote Tesla Motors CEO Elon Musk in a post on the Internet publishing site Medium. The action comes as an additional Tesla response in the wake of the two widely-reported Model S collisions in 2013 that resulted in underbody damage that led to car fires. Tesla had earlier provided an over-the-air software update to increase the default ground clearance of the Model S at highway speeds, thereby also reducing the odds of a severe underbody impact.

Study finds no benefit to delaying or weakening ZEV policies to drive transition to electric drive
March 14, 2014
A study by a team from the Howard H. Baker Center for Public Policy at the University of Tennessee, Knoxville and Oak Ridge National Laboratory concludes that starting the California ZEV (Zero Emission Vehicle) mandates five years earlier or doubling their intensity increases upfront costs but also increases benefits by a greater amount.
Similarly, the study found, delaying the ZEV mandate is estimated to reduce upfront costs, but cause an even greater reduction in the present value of benefits. Even using pessimistic assumptions about future costs of electric drive technologies, the study showed no net benefit to delaying or weakening ZEV requirements. The simulations also show the important synergies between California and US transition policies, the authors noted.

In an address at the opening ceremony of CeBIT 2014 in Hanover in the presence of Federal Chancellor Dr. Angela Merkel, the British Prime Minister David Cameron, the Minister-President of Lower Saxony Stephan Weil and Prof. Dieter Kempf, President of BITKOM, the IT industry Association, Winterkorn declared that the increasingly intensive networking of cars with their surroundings and automatic driving would be the key topics for the intelligent mobility of the future.
nanoFLOWCELL unveils flow cell battery prototype vehicle
March 05, 2014
|Powertrain of the QUANT. The two 200L (400L, 106 gallons US total) electrolyte tanks are packaged in the rear and central tunnel of the vehicle. Click to enlarge.|
Liechtenstein-based nanoFLOWCELL unveiled the QUANT e-Sportslimousine, a prototype vehicle equipped with a nanoFLOWCELL flow cell battery powertrain, at the Geneva Motor Show. This flow cell system supports an electric driving range of between 400 to 600 km (249 to 373 miles) in the QUANT e-Sportlimousine prototype, the company claims.
Flow cells or flow batteries combine aspects of an electrochemical battery cell with those of a fuel cell. The electrolytic fluids in flow cells—usually metallic salts in aqueous solution—are pumped from tanks through the cell. This forms a kind of battery cell with a cross-flow of electrolyte liquid. One advantage of this system in general is that the larger the storage tanks for the electrolyte fluid are, the greater the energy capacity. Too, the concentration of an electrolytic solution contributes to the the quantity of energy that it transports.

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.

Tesla shipped 6,892 Model S units in Q4 2013, 22,477 full year; battery Gigafactory announcement next week
Tesla Motors announced record deliveries of 6,892 Model S vehicles worldwide in the fourth quarter of 2013, with 22,477 vehicles in the full year. For the quarter, non-GAAP revenue was $761 million, up 26% from Q3. GAAP revenue for Q4 was $615 million, up 43% from Q3. Q4 non-GAAP net income was $46 million, or $0.33 per share, while Q4 GAAP net loss was $16 million or $(0.13) per share.
The differences between GAAP and non-GAAP are primarily due to lease accounting for resale value guarantee (RVG) and employee stock-based compensation as a result of the increase in stock price last year. The results show Tesla moving closer to break-even or profitability even on a GAAP basis. (GAAP net loss per share for the quarter ending 30 Sep 2013 was $(0.32), and for Q4 of 2012, $(0.79). For the full 2013 calendar year, net loss per share $(0.62), while for all of 2012, it was $(3.69).
New 3-speed EV powertrain to offer 10-15% improvement in EV range
February 19, 2014
|Compared to a single-speed EV or HEV transmission, DSD’s MSYS 3-speed system provides a 40% weight saving and 10-15% lower energy consumption. Click to enlarge.|
UK-based Drive System Design is developing a new EV powertrain based on an alternate approach to powershifting (no torque interrupt) achieved by separating the existing functions of a synchronizer. The integrated design of an axial flux YASA motor (earlier post) with the multi-speed transmission contributes to simplification of the motor cooling system, electrical architecture and powertrain control system.
The MSYS system can mean a 10-15% improvement in the range of electric vehicles, the company says. (Earlier post.) The company was recently showcased at the Cleantech Innovate 2014 event by the UK’s LowCVP organization (Low Carbon Vehicle Partnership), along with 7 other companies. DSD was the winner of a LowCVP commendation as the most impressive of the road transport-focused entries.
Study finds that EV-specific factors rather than socio-demographic variables better predictors of EV uptake
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.
