Drive circuitry of an electric vehicle enabling rapid heating of the battery pack at low temperatures
Summary: Heating battery at low temperatures is fundamental to avoiding the range anxiety and the time-consuming charging associated with electric vehicles (EVs). One method for achieving fast and uniform battery heating is to polarize the cell under pulse currents. However, the on-board implementat...
