Abstract
When an air-conditioner operation mode signal AM representative of a confirmation to permit the starting of a motor-driven compressor is supplied from an air-conditioner control unit to a battery management unit, the battery management unit detects power supply conditions including a voltage, a ground fault, a wire disconnection, etc. of a high-voltage battery, and supplies a start permission signal AUX2 indicative of a permission to start the motor-driven compressor to the air-conditioner control unit depending on the detected power supply conditions. After having received the start permission signal AUX2, the air-conditioner control unit turns on an air-conditioner inverter drive signal DAI to operate the motor-driven compressor.
