Study finds households manage charging of PHEVs without help from online tools

Green Car Congress

Households with plug-in hybrid vehicles (PHEVs) and smart meters actively managed how, when and where they charged their cars based on electricity rates but rarely took advantage of online feedback, according to a two-year study by a team at the University of Colorado Boulder’s Renewable and Sustainable Energy Institute ( RASEI ).

CMU county-level study shows plug-ins have larger or smaller lifecycle GHG than gasoline ICE depending on regional factors

Green Car Congress

A US-wide county-level study comparing lifecycle greenhouse gas (GHG) emissions from several light-duty passenger gasoline and plug-in electric vehicles (PEVs) has found that PEVs can have larger or smaller carbon footprints than gasoline vehicles depending on regional factors and the specific vehicle models being compared.

Study Concludes That Smaller Capacity PHEVs Would Be a “Robust” Option for Minimizing Fuel Consumption, Cost and GHG Emissions

Green Car Congress

A team of researchers from Carnegie Mellon University has analyzed the impact of plug-in hybrid electric vehicle (PHEV) battery pack size on fuel consumption, cost and greenhouse gas emissions over a range of charging frequencies (distance traveled between charges).

Sure — surge pricing is terrible and should be a universally reviled practice , but you can’t argue with the flexibility that variable pricing offers large venues, and the ability to offer discounted or even free charging during otherwise quiet parking days is one possible silver lining there. “The
