Abstract
A battery system for an electric vehicle, including: a high voltage (HV) battery subsystem including a battery cell stack with battery cells electrically connected between stack nodes; a low voltage (LV) battery subsystem including a LV battery and a supply node connectFed to the LV battery; a DC/DC converter with a primary coil in the HV battery subsystem and a secondary coil in the LV battery subsystem, wherein the primary coil is connected to one of the stack nodes via a switch. A threshold signal indicative of a voltage at the supply node may be generated in the LV battery subsystem and may be transmitted to the HV battery system. A state of the switch may be controlled based on the threshold signal.
