Argonne study finds BEVs can have lowest scheduled maintenance costs, but highest cost of driving

Green Car Congress

Researchers at Argonne National Laboratory, with colleagues from Lawrence Berkeley, Oak Ridge, and National Renewable Energy labs, and the University of Tennessee, have published a comprehensive analysis of the total cost of ownership (TCO) for 12 sizes of vehicles ranging from compact sedans up to Class 8 tractors with sleeper cabs.

CMU team details impact of regional and drive-cycle variations on degradation of a PHEV battery pack

Green Car Congress

A team at Carnegie Mellon University (CMU) led by Dr. Jeremy Michalek has investigated the implications of regional and drive cycle variations on the degradation of a plug-in hybrid electric (PHEV) battery. a) Capacity Fade in Phoenix, comparison of air cooling vs no cooling for two drive cycles. (b)

ICCT LCA study finds only battery and hydrogen fuel-cell EVs have potential to be very low-GHG passenger vehicle pathways

Green Car Congress

This is especially important for assessing the GHG emissions of PHEVs. The total also accounts for the GHG emissions from manufacturing solar panels and wind turbines that produce renewable electrical power to fuel battery EVs, as well as energy losses in electricity transmission and EV charging.

TÜV lifecycle analysis shows Mercedes-Benz E 350 e PHEV cuts GHG footprint 44% compared to E 350 CGI; equivalent NOx

Green Car Congress

If the calculation is based on the use of renewable energy for external charging, the CO 2 emissions can be reduced by as much as 63%. Although in the production phase, the PHEV gives rise to a higher quantity of CO₂-emissions caused by the additional hybrid-specific components, over the entire lifecycle it shows clear advantages.

UC Riverside reinforcement-learning-based real-time energy management system can improve PHEV efficiency by almost 12%

Green Car Congress

Researchers at the University of California, Riverside’s Bourns College of Engineering have demonstrated that a new, data-driven, reinforcement-learning-based, real-time energy management system (EMS) can improve the efficiency of current plug-in hybrid electric vehicles (PHEVs) by almost 12% compared to the standard, binary mode control strategy.

PNNL study finds that PHEVs and BEVs could serve as feasible resource to offset grid imbalances caused by integration of large amounts of intermittent wind generation

Green Car Congress

trafficThis scenario is currently less desirable to automotive manufacturers, but provides an additional resource benefit to PHEV/BEVs by theoretically doubling their capacity value to the grid. V2GFull varies not only the charging of the vehicle battery, but also can vary the discharging of the battery back into the power grid.

ORNL study finds best current use of natural gas for cars is efficient production of electricity for EVs

Green Car Congress

The baseline for comparison is based on a 2012 2.4 For the PHEV cases, both charging from the US mix and charging from a natural gas turbine with a 45% electrical generating efficiency were considered. The RPS cases illustrate the effectiveness of renewable power generation on the EV. Curran et al. Click to enlarge.
