GM provides technical details of the Gen 2 Voltec propulsion system used in the 2016 Volt
April 23, 2015
The second-generation “Voltec” extended range electric powertrain applied in the MY2016 Chevy Volt (earlier post) marks a significant evolution in the electric drive technology platform from its first-generation origins. After proving a initial look at the design and capability of the different components (earlier post) late last year, GM is now providing deeper technical insight into the second-generation platform.
At the SAE 2015 World Congress in Detroit this week, GM engineers are presenting four papers on the technology of the Gen 2 Voltec propulsion system: an overview of the system and the realized improvements in efficiency and performance; a paper on the significantly re-engineered traction power inverter module (TPIM); a paper on the design and performance of the new electric motors used in the propulsion system; and a paper on the selection and design of the optimized gasoline-fueled 1.5-liter range extender engine.

Lightning Hybrids (LH), a provider of hydraulic hybrid drive systems for fleet vehicles such as shuttle buses, delivery vehicles and work trucks (earlier post), has released some results from its ongoing emissions testing with SGS Environmental Testing Corporation. Broadly, the test results show significant reductions in NOx, particularly against a non-hybrid diesel baseline, and fuel economy improvements of up to 18% for the vehicle and under the drive cycles tested.
By design, LH noted, a hybrid drive system provides benefits during a vehicle’s braking and subsequent acceleration phases, so not all drive cycles will take equal advantage of the system. For example, an urban delivery truck which stops many times per mile will benefit strongly, whereas a truck that spends most of its time on the highway would not be a good candidate for any form of hybridization.

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.

Kia unveils Soul-based e-AWD Trail’ster Concept; through-the-road hybrid
Kia Motors America (KMA) unveiled the Trail’ster e-AWD concept at the 2015 Chicago Auto Show. The Trail’ster, based on Kia’s Soul urban passenger vehicle, is primarily powered by a 1.6-liter turbocharged 4-cylinder engine delivering 185 horsepower (138 kW) and 185 lb-ft (251 N·m) of torque through a six-speed automatic transmission, matched to an electric all-wheel-drive system on the rear axle intended for low-speed assist, enhanced launch acceleration and improved traction in inclement weather or off-road situations. In addition, this approach helps mitigate turbo lag by providing instant torque.
The system also improves fuel economy over standard all-wheel-drive setups by operating only when needed and serving as an energy recovery mechanism. Further defining the near future perspective of Soul as a capable and efficient all-wheel-driver runner, the Trail’ster arrives as a “Through-the-Road” hybrid—i.e., the two power sources (front gasoline engine and rear electric motor) meet “through the road,” as opposed to inside the transmission with a common mechanical driveline connection.
ALABC showcased three 48V hybrid demonstrators at AABC featuring advanced lead-carbon batteries
February 10, 2015
The Advanced Lead Acid Battery Consortium (ALABC) last month showcased three hybrid electric concept vehicles resulting from its R&D program that demonstrate the real-world potential of lead-carbon batteries in 48V architectures. The cars, two of which were produced in association with major OEMs (Ford and Hyundai/Kia), exhibit substantial environmental and fuel-efficient benefits through low-cost hybridization. The vehicles were part of the ALABC display at the Advanced Automotive Battery Conference (AABC Europe 2015) held at the Rheingoldhalle in Mainz, Germany.

Nissan unveils front-engined, front-wheel drive hybrid GT-R LM NIMSO Le Mans challenger
Nissan revealed its Le Mans challenger, the Nissan GT-R LM NISMO, during a commercial break for Super Bowl XLIX. Nissan interpreted the sport’s technical regulations in an innovative way, producing a front-engined, front-wheel-drive car that is powered by a V6 3.0-liter twin turbo gasoline engine and a kinetic energy recovery system.
The front tires are wider than those in the rear (14" vs 9") due to the way that mass is distributed in the car. Nissan moved the weight bias forwards to provide traction for the front-engined, front-wheel drive. The aero is also moved forward; hence, Nissan moved the capacity of the tires forward to match the weight distribution. The aero center of pressure, the mass center of gravity and the tire capacity are all in harmony, said Ben Bowlby, Nissan’s LM P1 Team Principal and Technical Director. That means bigger tires at the front than the rear.
Lux Research: despite cheap oil, niche plug-in vehicle sales will be resilient; conventional hybrids to be hardest hit
The current plunge in oil prices will likely negatively affect plug-in and hybrid vehicle sales in the short term; automakers such as BMW are already warning of lower sales of plug-in vehicles given the market context. However, an analysis by Lux Research suggests that despite some decrease in sales, sales of plug-in vehicles will likely be resilient, and rebound as oil prices rise back to the prior higher levels over time.
In the likely case of only a gradual return to previous higher prices—which Lux calls the “cheap oil” scenario in its analysis—then electric vehicle (EV) sales will dip by 20% for a number of years, while plug-in hybrid (PHEV) sales will dip by about 14% during that same period, the research firm found. The forecast declines are relative to the other forecasted scenario, in which oil prices rebound much more quickly—the “stable oil” scenario.

|SiC PCU under the hood of the Camry hybrid test vehicle. Click to enlarge.|
Toyota will begin the on-road testing of silicon carbide (SiC) power semiconductors in Japan this year, using a Camry hybrid prototype and a fuel cell bus. The tests will evaluate the performance of the SiC technology, which could lead to significant efficiency improvements in hybrids and other electric-drive vehicles. (Earlier post.)
Power semiconductors are found in power control units (PCUs), which are used to control motor drive power in hybrids and other vehicles with electric powertrains. PCUs play a crucial role in the use of electricity, supplying battery power to the motors during operation and recharging the battery using energy recovered during deceleration. At present, power semiconductors account for approximately 20% of a vehicle’s total electrical losses; raising the efficiency of the power semiconductors is a promising way to increase powertrain efficiency.
Renault Sport F1 introduces revamped 2015 hybrid power unit
January 28, 2015
|Renault Energy F1-2015 Power Unit. Click to enlarge.|
Renault Sport F1 has unveiled its 2015 power unit for Formula 1 racing, which incorporates a number of changes compared to its 2014 predecessor (earlier post). 2015 is the second year of competitive use for the power units that feature a V6 turbocharged internal combustion engine coupled to energy recovery systems.
In introducing the new unit, Renault Chief Technical Officer Rob White noted that the second year of a new engine “is always difficult. The 2015 power unit project was started six months before the 2014 units took to the track, ie. before we had any significant experience of the technology. Then we also needed to consider the issues arising during the season. It creates a need to be both forward thinking and reactive. Splitting resources between projects is therefore a delicate balancing act, in the short, mid and long term. While certain decisions can be taken upstream, a number of design decisions were taken quite late in the day, in order to benefit from the experience of the 2014 power unit. The result is a power unit that is very different to its predecessor,” he said.

UQM Technologies granted patent on permanent magnet electric motor design using non-rare earth magnets
January 20, 2015
UQM Technologies Inc. has been granted a US patent (8,928,198, “Brushless PM machine construction enabling low coercivity magnets”) for an electric and hybrid electric vehicle motor design using non-rare earth magnets. The patent covers the unique magnet geometry and the method of manufacturing the motor.
The majority of electric and hybrid electric vehicles produced today use permanent magnet (PM) motors with rare-earth magnet materials because of the high coercivity of the rare earth materials. Coercivity is a measure of the reverse field needed to drive magnetization to zero after being saturated—i.e., it is a measure of the resistance to demagnetization. The new UQM design enables the use of low coercivity magnets, such as Aluminum Nickel Cobalt (AlNiCo) or Iron Cobalt Tungsten (FeCoW), in PM machines.

|The new Chevy Volt has a decidedly more sculpted look than its predecessor. Click to enlarge.|
Chevrolet unveiled the second-generation Volt extended range EV at the North American International Auto Show. With a sportier design and an entirely new drive system (earlier post), the 2016 Volt electric car features a higher capacity battery pack and 50 miles of all-electric range (MY 2015 = 38 miles); greater efficiency; and stronger acceleration. GM estimates fuel economy to be 41 mpg combined (MY 2015 = 37 mpg) with 102 mpge (MY 2015 = 98 mpge). The 2016 Volt goes on sale in the second half of 2015.
The new propulsion system will offer a General Motors’-estimated total driving range of some 420 miles and with regular charging, owners are expected to travel more than 1,000 miles on average between gas fill-ups. Currently, drivers of the first-generation Volt are averaging more than 900 miles between fill-ups. Put another way, drivers of the first gen Volt drive electric about 80% of the time, said Andrew Farah, chief vehicle engineer for both generations of the Volt. Farah suggested that the new Volt may be able to boost that figure to nearly 90% in moderate climates.
Mercedes-Benz unveils self-driving fuel cell hybrid luxury concept at CES; novel body structures
January 06, 2015
In a world premiere, Mercedes-Benz unveiled the self-driving fuel cell hybrid electric F 015 Luxury in Motion concept at the CES. In addition to its autonomous driving capability, a key aspect of the research vehicle is the continuous exchange of information between vehicle, passengers, and the outside world.
The drive system is based on the pioneering F-CELL PLUG-IN HYBRID system seen in the F 125! research vehicle from 2011 (earlier post), and combines on-board generation of electricity with an exceptionally powerful and compact high-voltage battery. The pressure tank made from CFRP is designed to store the hydrogen. (The drive system in the 2011 F 125!, which generated a continuous output of 170 kW (231 hp) and a peak output of 230 kW (313 hp), featured the latest Mercedes-Benz stack, a 10 kWh Li-sulfur battery, four wheel motors and structure-integrated hydrogen storage with MOFs.)
The stack in the F 125!, which is further improved with respect to performance, consumption and practical suitability, provides the power for four electric motors installed near the wheels. The modular e4MATIC system, which also uses improved drive components from the SLS AMG E-CELL, . This accelerates the F 125! to 100 km/h in 4.9 seconds, with a top speed of 220 km/h (137 mph).
Cambridge team successfully tests hybrid light aircraft; 30% fuel savings
December 23, 2014
|Hybrid in flight. Click to enlarge.|
Researchers from the University of Cambridge, in association with Boeing, have successfully tested a light aircraft powered by a parallel hybrid-electric propulsion system, in which an electric motor and gasoline engine work together to drive the propeller. The demonstrator aircraft—based on a single-seat, ultralight Song motor glider—uses up to 30% less fuel than a comparable plane with a gasoline-only engine. The aircraft is also able to recharge its batteries in flight, the first time this has been achieved.
The hybrid system was designed and built by engineers at Cambridge with Boeing funding support. The hybrid aircraft uses a combination of a ~7 kW Honda 4-stroke piston engine and a 10 kW electric motor/generator, coupled through the same drive pulley to spin the propeller. The hybrid system delivers approximately the same power as the standard engine for the Song—a 15 kW Bailey V5 single-cylinder 4-stroke.
ORNL, UT Austin team proposes optimization framework for hybrids; balancing fuel consumption, motor efficiency, battery capacity and life
December 22, 2014
Researchers at Oak Ridge National Laboratory and the University of Texas at Austin have developed an optimization framework for hybrid-electric and plug-in hybrid-electric vehicles (HEVs and PHEVs) including fuel consumption, motor efficiency, and battery capacity and lifetime. The approach, detailed in a paper accepted for publication in the IEEE Transactions On Control Systems Technology, is intended to enhance the understanding of the associated tradeoffs among the HEV subsystems—e.g., engine, motor, battery—and to investigate the related implications for fuel consumption and battery capacity and lifetime.
With the framework, the performance of the subsystems can be tailored according to consumer preferences, such as reducing fuel consumption or extending battery life. Further, the ability to control battery performance indices—e.g., temperature—enables operating the battery at a higher target SoC (state of charge) without incurring safety concerns. As a result, the results of such analyses could have significant implications for the related HEV and PHEV ownership and warranty costs.

CPT, together with other sponsors of the event, including AVL and Ricardo, is in the vanguard of 48V mild hybrid developments intended to address the ever-tightening European CO2 regulations and potentially a new and more aggressive test cycle—i.e., the Worldwide harmonized Light vehicles Test Procedures (WLTP).
MHI completes development of next-generation LNG carrier; apple-shaped tanks and hybrid propulsion
November 29, 2014
|Sayaringo STaGE. Click to enlarge.|
Mitsubishi Heavy Industries, Ltd. (MHI) has completed development of the “Sayaringo STaGE,” a next-generation LNG (liquefied natural gas) carrier. The Sayaringo STaGE was developed as a successor to the Sayaendo (earlier post), the company’s LNG carrier evolved from carriers with Moss-type spherical tanks that offer a high level of reliability. (Moss-type LNG carriers use independent spherical cargo tanks supported by a cylindrical skirt integrated with the hull and covered with a hemispherical steel cover attached to the main deck.)
While the Sayaendo (sayaendo = peas in a pod in Japanese) features a peapod-shaped continuous cover for the Moss spherical tanks that is integrated with the ship’s hull, in lieu of a conventional hemispherical cover, the new Sayaringo (ringo being the Japanese word for “apple”) STaGE adopts apple-shaped tanks, resulting in nearly a16% increase in LNG carrying capacity without changing the ship’s width. Further, a hybrid propulsion system has boosted fuel efficiency by more than 20% compared to the Sayaendo (and more than 40% vis-à-vis earlier carriers).

|BMW 3 Series Plug-in hybrid prototype. Click to enlarge.|
BMW has unveiled a 3 Series plug-in hybrid prototype. Combining a four-cylinder TwinPower Turbo gasoline engine from the new Efficient Dynamics engine family with an electric motor, the BMW 3 Series plug-in hybrid prototype offers performance on a par with a conventionally powered BMW 3 Series six-cylinder model, combined with a significant reduction in fuel consumption.
In addition, BMW outlined its work on Power eDrive next-generation electrification platforms—an effort to deliver “highly electrified” plug-in hybrids with higher-powered electric motors and batteries with twice the capacity of present versions. Future plug-in hybrid concepts, said BMW, will use the electric motor—the main source of power for everyday driving—to drive the rear wheels, while a second electric motor driving the front wheels will create an all-electric road-coupled all-wheel-drive system. At the same time, an internal combustion engine will also supply power to the front axle.
Bus maker Alexander Dennis to fit GKN Gyrodrive flywheel hybrid systems to 250 buses; partners on international development
November 24, 2014
|Gyrodrive. Click to enlarge.|
Alexander Dennis Limited (ADL), Britain’s biggest bus and coach manufacturer, has chosen GKN Hybrid Power as a preferred partner and committed to the purchase of 250 of its Gyrodrive electric flywheel hybrid systems (earlier post). ADL will focus initially on the introduction of the low emission technology to bus fleets in London and Oxford but anticipates rapid deployment across the UK in the next few years. It will also be working closely with GKN to develop the technology for international markets.
Instead of a battery, the Gyrodrive system uses a magnetically loaded high-speed carbon-fiber flywheel to store the energy generated by a bus as it slows down to stop. It then utilizes the stored energy to power a GKN EVO electric motor which helps accelerate the bus back up to speed, generating significant fuel savings of up to around 25% at a considerably lower cost than battery-hybrid alternatives.
Lux Research: fuel cell vehicles lag other drivetrains in terms of cost of ownership; ICE and HEV lowest cost
Based on an analysis of various cost of ownership scenarios for various drivetrains, including internal combustion engine (ICE) gasoline and diesel; hybrid (HEV); battery-electric (EV); plug-in hybrid electric (PHEV); and fuel cell vehicles, Lux Research concludes that fuel cell vehicles (FCVs) are “solidly in a laggard position.”
The Lux analysts ran scenarios associated with operation and ownership, broken out into fuel cost alone; fuel cost plus operation, but excluding purchase or lease; and fuel cost plus operation, including purchase or lease (total ownership cost). When looking at fuel cost only, EVs lead the way due to the relatively low price of electricity, followed by various types of hybrids (HEVs and PHEVs). Fuel cell vehicles can match EV fuel costs at $3/kg dispensed H2—a price highly unlikely in near-term, Lux said.

The new converter raises the MiEV system to 700 volts and helps to further improve energy output and efficiency from both the electric motor as well as the generator.
EALABC paper outlines approach to 48V hybrid systems with advanced lead-carbon batteries
November 19, 2014
The European Advanced Lead-Acid Battery Consortium (EALABC) is delivering a paper this week outlining the consortium’s approach to 48V hybridization at the 2nd International Conference on Advanced Automotive 48V Power Supply Systems in Düsseldorf. The EALABC focus is on the environmental and cost benefits of current and future advanced lead-carbon batteries for 48V hybrid vehicles.
The state-of-charge (SoC) of current lead-carbon batteries is typically maintained at between 30 and 50%, with the voltage and amperage meeting VDA requirements by not exceeding 54V at 150A when recovering joules of energy from vehicle deceleration (kinetic energy recovery) and exhaust gas energy recuperation (thermal energy recovery), also dropping not less than 38V at 180A when discharging energy for engine starting and torque assist. Advanced lead-carbon batteries for vehicles currently under development will be capable of operating in the 30 to 70% SoC range at 12.5kW.
Volkswagen outlines a range of near-term technologies for reducing fuel consumption and emissions; stop-start 2.0, 10-speed DSG
November 11, 2014

ICCT study finds state EV incentives playing a significant role in driving sales
October 31, 2014
A study by a team from the International Council on Clean Transportation (ICCT) shows that state electric vehicle incentives are playing a significant early role in reducing the effective cost of ownership and driving electric vehicle sales.
As described in their white paper, “Evaluation of state-level US electric vehicle incentives”, the researchers found that some of the states with the largest electric vehicle incentives—i.e., California, Georgia, Hawaii, Oregon, and Washington—have electric vehicle sales shares that are approximately 2–4 times the national average. A statistical regression revealed that the total monetary benefit to consumers from state incentives significantly positively correlates with BEV sales when all 50 states and the District of Columbia are included.
