Schaeffler preparing 48V mild hybrid Audi TT for road testing
September 30, 2015
Schaeffler has been testing and demonstrating the performance capabilities of 48 volt hybridization in a range of concept vehicles including the“Gasoline Technology Car” (GTC), co-developed with Ford and Continental and the “Schaeffler Efficient Future Mobility North America” vehicle, as launched at the 2015 Detroit Motor Show (NAIAS) (earlier post). Schaeffler is now applying 48V hybridization to an Audi TT.
The drive for the “Schaeffler System 48 V” is based around an electrified rear axle which complements the front-wheel drive internal combustion engine. An additional belt-driven starter generator is connected to the engine which also operates at 48 V. The 48 V on-board electric subsystem uses a lithium-ion battery as its energy store. It is connected via a voltage transformer to the 12 V on-board electric system which powers all the different electrical components in the vehicle, from headlights to seat adjusters.
JAC and Ricardo develop production version of HyBoost concept; seeking 30% boost in fuel economy with same performance
Anhui Jianghuai Automobile Group Co Ltd (JAC) and Ricardo are collaborating on a project to develop the Ricardo HyBoost concept (earlier post)—a combination of low-cost technologies to deliver improved performance and fuel economy which featured recently in the Ricardo Centenary celebrations —into volume production on a JAC vehicle.
The Ricardo HyBoost concept is based on a downsized, highly boosted turbocharged direct injection gasoline (TDGI) engine giving improved fuel economy at low cost, linked to a 48V electrical architecture including a belt starter generator (BSG), DC-DC converter and a lithium-ion battery for energy storage.
Schaeffler introduces new high-voltage P2 hybrid module; up to 800 N·m; first production application in China in 2017
September 29, 2015
Schaeffler has developed a new P2 (parallel, two-clutch) high-voltage hybrid module—arranged between the internal combustion engine and transmission—that can transmit engine torques of up to 800 N·m (590 lb-ft) to the transmission without having to incorporate a commensurately expensive clutch.The new generation P2 hybrid module can be used in both medium- and very high-performance transmission concepts—e.g., from mild to plug-in hybrids.
The high-torque module distributes the flow of forces in an innovative way; the pathway of torque conveyance depends on its direction. Torques are transmitted to the crankshaft via a 300 N·m disconnect clutch, while traction torques from the internal combustion engine are transmitted to the transmission via a one-way clutch. The clutch can therefore have a compact design, even at high torques, with the corresponding advantages in terms of space utilization and cost. Schaeffler showcased the unit at the International Motor Show (IAA) in Frankfurt.
Oak Ridge AMIE demo integrates 3D-printed building, natural gas hybrid with bi-directional wireless power transfer
September 24, 2015
A research demonstration unveiled at the Department of Energy’s Oak Ridge National Laboratory (DOE ORNL) combines clean energy technologies into a 3D-printed building and a 3D-printed natural gas-powered hybrid vehicle to showcase a new approach to energy use, storage and consumption. The Additive Manufacturing Integrated Energy (AMIE) demonstration, displayed at DOE’s Office of Energy Efficiency and Renewable Energy Industry Day event, is a model for energy-efficient systems that link buildings, vehicles and the grid.
An ORNL team worked with industrial partners to manufacture and connect a natural-gas-powered hybrid electric vehicle with a solar-powered building to create an integrated energy system. Power can flow in either direction between the vehicle and building through a lab-developed wireless technology. The approach allows the car to provide supplemental power to the 210-square-foot building when the sun is not shining.

60% of $18B in US clean energy tax credits 2006-2012 went to top 20% by income; 90% in the plug-in program
August 30, 2015
A working paper by a team at the Energy Institute at Haas, University of California, Berkeley, has found that 60% of the $18 billion in US federal income clean energy tax credits issued between 2006 and 2012—e.g., for weatherizing homes, installing solar panels, and buying hybrid and electric vehicles—went to the top income quintile in the US (above $200,000 per year). The bottom three quintiles (up to $75,000 per year) received about 10%.
The most extreme case, Severin Borenstein and Lucas Davis found through their examination of tax return data from the IRS, is the program aimed at electric vehicles—the top income quintile received about 90% of all these credits. As a result of the work, Borenstein and Davis conclude that tax credits are likely to be much less attractive on distributional grounds than market mechanisms to reduce GHGs.

The PHEV port truck provides all-electric zero emissions driving capability as well as parallel and series hybrid operation.
CMU analysis finds BEVs powered with natural gas-based electricity have about 40% of the lifecycle GHGs of a conventional gasoline vehicle
August 21, 2015
According to a new lifecycle analysis by a team at Carnegie Mellon University, a battery electric vehicle (BEV) powered with natural gas-based electricity achieves around an average 40% lifecycle greenhouse gas (GHG) emissions reduction when compared to a conventional gasoline vehicle. Plug-in hybrids (PHEVs), either with a 30- or 60-km range, when powered by natural gas electricity, have the second lowest average emissions. Both BEVs and PHEVs provide large (more than 20%) emissions reductions compared to conventional gasoline, but none of them is a dominant strategy when compared to gasoline hybrid electric vehicles (HEVs), the team found.
Gaseous hydrogen fuel cell electric vehicles (FCEVs) and compressed natural gas (CNG) vehicles have comparable life cycle emissions with conventional gasoline, offering limited reductions with 100-year global warming potential (GWP) yet leading to increases with 20-year GWP. Other liquid fuel pathways using natural gas—methanol, ethanol, and Fischer–Tropsch liquids—have larger GHG emissions than conventional gasoline even when carbon capture and storage technologies are available. The study is published in the ACS journal Energy & Fuels.
2015 Harris Poll finds 48% of US car owners would consider hybrid for new car, same as in 2013; plug-in consideration up 2 points
August 20, 2015
A new Harris Poll of 2,225 US adults (aged 18 and older) has found that 48% of American car owners (or anticipated owners) say they’d consider a traditional hybrid the next time they’re in the market for a new vehicle—a result identical to 2013 findings. Harris recorded lower consideration levels for plug-in vehicles, whether they be plug-in hybrids (29%, up 2 percentage points) or pure electrics (21%, also up 2 points).
An additional two in ten would consider a diesel (19%, up 3 points), while 35% would consider a smaller or gas powered vehicle to save on operating costs (down 3 points).

2016 Chevrolet Volt EPA-rated at 53 miles all-electric range
August 04, 2015
The Chevrolet Volt’s all-new second-generation Voltec extended-range electric propulsion system (earlier post) delivers 53 miles (85 km) of all-electric range, based on EPA testing. That is nearly a 40% improvement over the first-generation Volt, and a 6% boost over the projected 50-mile (80 km) AER estimated at the new Volt’s unveiling in January. (Earlier post.)
Chevrolet expects many next-generation Volt owners will use power solely from their batteries for more than 90% of trips. Today, Volt owners use battery power on 80% of their trips, according to GM. The additional range would enable the average Volt owner to travel well over 1,000 miles (1,609 km) (in multiple trips) between gas fill ups, if they charge regularly.
Researchers find HEV under real-world conditions delivers significantly greater fuel economy benefits than EPA “sticker” values
August 03, 2015
In a new study reported in the ACS journal Environmental Science & Technology, a team at the University of Vermont found that when including real-world road grade and ambient conditions compared to controlled laboratory tests, fuel consumption benefits for a hybrid electric vehicle (HEV) under study increased by 18% highway and 33% city compared to estimates based on EPA adjusted fuel economy “sticker” values. (The vehicles under study were a conventional and hybrid Camry).
In other words, they found that they real-world fuel economy benefit of adoption of HEVs may be better than for estimates based on EPA “sticker” fuel economy alone. The duo, Britt A. Holmén and Karen M. Sentoff, suggested that based on these results, more positive forecasts for future petroleum and corresponding CO2 emissions savings from increased hybridization of the passenger vehicle fleet may be warranted.

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.
ICCT: ongoing cost reductions in full- and mild-hybrid systems could bring them into consumer mainstream by 2025
July 24, 2015
According to a new technology briefing paper on hybrid system technologies by John German at the International Council on Clean Transportation (ICCT), the costs of full-function hybrid systems are likely to drop to half the cost of their 2010 counterparts before 2025.
Combined with the development of mild-hybrid systems (belt-alternator or 48-volt system)s—which will likely provide one-half to two-thirds the fuel-efficiency benefits of full-function hybrids at less than half the cost—these levels of cost reductions could put both those technologies into the consumer mainstream by 2025, at least from a cost of technology point of view, German suggests.

Using the PHEV (Plug-In Hybrid Electric Vehicle) to Transition Society Seamlessly and Profitably From Fossil Fuel to 100% Renewable Energy
July 17, 2015
CTO Efficient Drivetrains Inc. and UC-Davis Emeritus
Catherine J DeMauro
Abstract. The alternative-fuel car evolved to reduce exhaust emissions and other problems derived from burning fossil fuels. The PHEV (Plug-in Hybrid Electric Vehicle), a subset of the electric car, combines a primary electric motor with a much smaller back-up engine fueled with a hydrocarbon/biofuel mix. (In this paper PHEV refers solely to the long-range PHEV of 60 miles (100 km) electric-only range.) The PHEV does not require the heavy, costly batteries required by other electric cars, nor does it suffer from a limited range or poor freeway performance.
Though the PHEV combines the two types of energy and power, it is not merely a temporary “transition” between gasoline and diesel cars to pure electric cars. It is much more than that. It offers the solution to several significant transitions we need: moving society from burning fossil fuels to substituting renewable resource fuels such as solar, wind and biofuels; and from using fossil materials as fuel to using them for other recyclable uses.
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.
MAHLE control software combines GPS and topographical road data to manage plug-in hybrid energy consumption
July 15, 2015
As part of the continuing development of MAHLE’s range-extended electric vehicle (REEV) initiative (described and demonstrated at the Aachen Colloquium in 2012), the company’s Powertrain division has developed control software which can manage the consumption of battery energy for plug-in hybrids through a combination of GPS (global positioning systems) and topographical road data.
Bernie Porter, head of MAHLE’s Calibration and Controls Engineering group, said the company developed the software to use in research on its REEV test vehicle. MAHLE is investigating this powertrain technology using a range extender combustion engine and a demonstrator vehicle, both developed in house.
Volkswagen launches new Passat GTE plug-in hybrid in Europe
July 14, 2015
Volkswagen has launched its second plug-in hybrid based on a high-volume production model: the Passat GTE, available either as a sedan or Variant (wagon)—the first plug-in hybrid from Volkswagen to be sold as either. (Earlier post, earlier post.) The Passat GTE and Passat GTE Variant will arrive on the European market this autumn; in the first few countries advance sales have already begun. In Asia the launch will also be this year. In terms of the brand, the Passat GTE is a basic building block in Volkswagen’s electric motoring strategy.
Together with the plug-in hybrids from Audi (A3 e-tron, Q7 e-tron and R8 e-tron) and Porsche (Cayenne S E-Hybrid and Panamera S E- Hybrid), Volkswagen AG now has ten models in its portfolio driven wholly or partially on electric power. (The Volkswagen brand contributes the Golf and Passat GTE plug-ins, the low-volume XL1, and the battery-electric e-up! and e-Golf.) The Passat GTE is the first plug-in hybrid model being sold by the Group in the high-volume segment of large family cars.
Lightning Hybrids’ lightweight composite accumulator for hydraulic hybrid systems
July 11, 2015
Lightning Hybrids, developer and manufacturer of hydraulic hybrid systems for medium- and heavy-duty trucks and buses (earlier post), has provided some detail and background on a core component of its system: the hydraulic accumulator, or “mechanical battery”.
In the hydraulic hybrid system, hydraulic pumps and the lightweight accumulator store braking energy; upon acceleration the stored energy provides torque to the wheels. Up to a 35% gain in fuel efficiency in heavy drive cycles is achieved by regenerating the braking energy that is normally wasted to heat, and using this energy instead of the internal combustion engine for acceleration. Lightning Hybrids’ patented hydraulic hybrid system includes high-efficiency hydraulic pumps, a power transfer module, the lightweight accumulator system, a valve block, and a proprietary control system.
Navigant forecasts global annual sales of LDVs of 122.6M by 2035, up 38% from 2015
July 06, 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.
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.
BMW shows future drive technologies; 2 Series PHEV prototype, direct water injection in 3-cyl. engine, and fuel cell eDrive
July 02, 2015
During a driving event at the Miramas proving grounds in southern France, BMW presented future drive technologies, including the prototype of a BMW 2 Series Active Tourer with plug-in hybrid drive. This application of BMW eDrive technologies features the first PHEV system with a front/transverse-mounted combustion engine, high-voltage generator and road-linked all-wheel drive via an electric drive system at the rear axle.
The company also showcased the use of direct water injection to enhance the efficiency of combustion engines at higher performance levels while also significantly reducing fuel consumption and emissions in key driving cycles.

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:

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.
Emissions testing shows Lighting Hybrids hydraulic hybrid drive delivers significant reduction in NOx, up to 18% improved fuel consumption
April 21, 2015
|The LH gasoline hydraulic hybrid shows an extreme reduction in NOx compared to a diesel baseline. Source: Lightning Hybrids. Click to enlarge.|
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.
