HYBRID VEHICLE WITH MEANS FOR DISCONNECTION OF A DEPLETED AUXILIARY BATTERY IN ORDER TO ALLOW FOR MORE RAPID MAIN BATTERY CHARGING

摘要

A sub DC/DC converter converts an output voltage of a charger into a level of an output of an auxiliary battery, and outputs the output voltage to a power supply line connected to a PLG-ECU and the auxiliary battery. A control unit interrupts a current path from the power supply line to the auxiliary battery when a voltage of the sub auxiliary battery is equal to or lower than a prescribed value.
