Abstract
This electric power system controller for an automobile secures satisfactory driving control of a vehicle and outputs 100 V AC using electric power from a secondary battery. The stop of the 100 V AC output is determined by a 100 V AC inverter according to a state of the 100 V AC inverter, a vehicle control system, or an AC plug receptacle 50 or a state represented by the temperature, inter-terminal voltage, and remaining capacity SOC of a battery which exchanges electric power with a driving motor (S100 to S109, S114). Further, a charge discharge state is determined from the charging and discharge current and charge and discharge integration amount and the 100 V AC output is limited by the 100 V AC inverter (S108, S110, S116).
