Study finds energy savings of PHEVs relative to HEVs dependent on charging coverage and daily VMT

Green Car Congress

A study based on a spatial and longitudinal travel dataset by a team from Lamar University, Iowa State University and Oak Ridge National Laboratory found that whether plug-in hybrids (PHEVs) have lower energy costs that conventional gasoline vehicles (CGVs) or hybrid-electric vehicles (HEVs) depends on charger coverage.

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. Air cooling can increase battery life by a factor of 1.5–6, Credit: ACS, Yuksel et al. Click to enlarge.

6 DOE-funded applied battery research projects targeting Li-ion cells with >200 Wh/kg for PHEVs and EVs

Green Car Congress

The US Department of Energy (DOE) has six recently launched applied battery research (ABR) projects as part of its Vehicle Technologies portfolio. TIAX proposes that using a blended Si/hard carbon anode will allow the design of cells capable of delivering high energy during EV operation and high power during HEV mode of the battery.

CMU study finds small battery PHEVs and gasoline hybrids the least-cost policy solution to reducing gasoline consumption

Green Car Congress

The federal subsidy significantly favors larger battery packs to a stronger degree than their potential for additional gasoline savings. A 2011 paper by Michalek and colleagues found that strategies to promote adoption of HEVs and PHEVs with small battery packs offer more social benefits (i.e., Peterson and Michalek 2012.
