Abstract

An inlet (210) has a PISW to receive a reference voltage from a vehicle. When a discharging connector (100) is connected to the inlet (210), a PP terminal (PISW) receives the reference voltage. A detection circuit (540A) and a detection circuit (540B) selectively form a PISW circuit (a closed circuit) by a switch (S3B). Before the discharging connector (100) is connected to the inlet (210), the switch (S3B) is in a position to form the PISW circuit by the detection circuit (540A). When the discharging connector (100) is connected to the inlet (210), 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 (510) operates using power on a voltage line (L11, L12) 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.
