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.
