UC Davis study finds discontinuance rate of 21% for California PHEV adopters, 19% for BEV adopters

Green Car Congress

A new study by Scott Hardman and Gil Tal at the University of California, Davis has found that discontinuance occurs at a rate of 21% for California plug-in hybrid adopters and 19% for California battery electric vehicle adopters. For respondents that discontinued PHEV ownership 19% are unlikely to purchase one, 12.4%

MIT study finds materials risk exposure increases significantly with vehicle electrification

Green Car Congress

Now, a study by a team from MIT’s Materials Systems Laboratory, with support from Ford, provides insight into how electrification is changing vehicle composition and how that change is driving supply risk vulnerability. Modern automobiles are built with more than 2,000 different compounds comprising 76 different elements.

Study: PHEVs aren't plugged in as often as regulators assume

Green Car Reports

Plug-in hybrids only achieve their maximum emissions benefit when they are actually plugged in daily, and that isn't happening as often as regulators who set emissions rules assume, according to a new study from the International Council on Clean Transportation (ICCT).

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

Green Car Congress

The study considers five different powertrains (internal combustion engine, hybrid-electric, plug-in hybrid-electric, fuel-cell-electric, and battery-electric) and 12 cost components (purchase cost, depreciation, financing, fuel, insurance, maintenance, repair, taxes, registration fees, tolls and parking, payload capacity and labor).

Fraunhofer, KIT study finds CO2 mitigation potential of higher-range PHEVs greater than expected

Green Car Congress

In an open-access paper published in Scientific Reports , a team from Fraunhofer ISI and KIT (Karlsruhe Institute of Technology) has presented the first systematic overview of empirical findings on the electrification of vehicle mileage based on on actual PHEV (plug-in hybrid) and BEV (battery-electric vehicle) usage for the US and Germany.

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. 2013.12.054.

California PHEV Owners Return to Gas Power

The Truth About Cars

Yet 20 percent of California PHEV owners have gone back to gas-powered vehicles. Published in Nature Energy on April 26th by the Institute of Transportation Studies at the University of California, Davis, the study found that PHEV buyers in California were abandoning the technology at a rate of […].
