VEHICLE TRACTION BATTERY THERMAL CONDITIONING

摘要

A vehicle traction battery includes a plurality of battery cells and a battery energy control module (BECM) for charge-balancing the plurality of battery cells. The BECM is disposed within the vehicle traction battery and includes circuitry having at least one positive temperature coefficient component, such as a thermistor or silistor, connected to at least one of the plurality of battery cells for thermal conditioning of the plurality of battery cells.
