Abstract

An inlet has a PISW to receive a reference voltage from a vehicle. When a discharging connector is connected to the inlet, a PP terminal (PISW) receives the reference voltage. First and second detection circuits selectively form a PISW circuit (a closed circuit) by a switch. Before the discharging connector is connected to the inlet, the switch is in a position to form the PISW circuit by the first detection circuit. When the discharging connector is connected to the inlet, a power supply (or discharging) current is set based on a PISW potential and the vehicle starts discharging power. When the vehicle starts discharging power, a PWM signal generator operates using power on a voltage line as a power source, and a PWM signal is transmitted to the vehicle via a CP terminal (CPLT). The vehicle continues to discharge power by a power supply current based on the PWM signal.
