Study finds all-electric rideshare fleet could reduce carbon emissions, but increase traffic issues

Green Car Congress

Lead author Aniruddh Mohan and colleagues wanted to develop a method that evaluated the life-cycle costs and benefits for two battery-powered ridesource fleets and a gasoline-powered one. The analysis indicated that electrified fleets had 40-45% lower greenhouse gas costs per trip compared to the gasoline-powered version.

Penn State team devises new control strategy to enhance EV battery performance when driving in cold temperatures

Green Car Congress

Researchers at Penn State, with a colleague from EC Power, have devised a new control strategy that can rapidly restore EV battery power and permit full regeneration while driving at temperatures as low as −40 °C. The strategy involves heating the battery internally during regenerative braking and rest periods of driving.
