Researchers find HEV under real-world conditions delivers significantly greater fuel economy benefits than EPA “sticker” values

3 August 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.

OSU team develops new aqueous lithium-iodine solar flow battery; 20% energy savings over Li-I batteries

2 August 2015

After debuting the first solar air battery—a photo-assisted charging Li-O2 battery—last fall (earlier post), researchers at The Ohio State University led by Professor Yiying Wu have now developed a new system combining a solar cell and a battery into a single device.

The new aqueous lithium−iodine (Li−I) solar flow battery (SFB) incorporates a built-in dye-sensitized TiO2 photoelectrode in a Li−I redox flow battery via linkage of an I3/I based catholyte for the simultaneous conversion and storage of solar energy. During the photo-assisted charging process, I ions are photo-electrochemically oxidized to I3, harvesting solar energy and storing it as chemical energy.

Aeristech launches new 48V electric supercharger

31 July 2015

UK-based Aeristech has introduced a new 48V electric supercharger capable of continuous operation at high boost levels. Independently validated by Ricardo and MAHLE Powertrain UK, the technology provides greater efficiency and easier packaging than a mechanical supercharger or a two-stage turbocharger.

Aeristech said it overcame the thermal management issues that can restrict other electric boosting devices currently available on the market to only transient operation by using permanent magnet motor technology in place of the more usual switched reluctance type. This has been made cost-effective by developing a patented control and switching technology that enables the use of many cost-competitive components.

Daimler wraps up eMERGE EV 2-year fleet trial, launches larger eMERGE2 with EVs and PHEVs

31 July 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.

ARPA-E to award $14.5M to 5 projects to reduce energy use for transportation

31 July 2015

The Energy Department’s Advanced Research Projects Agency-Energy (ARPA-E) announced $14.5 million in funding for five projects in ARPA-E’s newest program, the Traveler Response Architecture using Novel Signaling for Network Efficiency in Transportation (TRANSNET).

Many travelers’ and commuters’ transportation choices waste significant amounts of energy due to traffic complications, convenience and variability in transportation styles and preferences. Even when presented with travel options that consume less energy, travelers and commuters may be less likely to use these energy-efficient options if they affect the duration, cost or convenience of a trip. TRANSNET systems will identify less energy-intense travel options for users using software accessible on smartphones or other communications devices and provide the most efficient transportation choices for travelers and commuters.
