Abstract:
A battery electric vehicle includes a high voltage rechargeable energy storage system (RESS). The RESS includes several battery modules reconfigurable among parallel and series arrangements. During reconfiguration transitions, a low voltage battery services low voltage loads of the battery electric vehicle. The low voltage battery is preconditioned in advance of reconfigurations.
