The second end includes a first electrical outlet and a second electrical outlet. The first electrical outlet includes a first voltage terminal connected to the first voltage line, a second voltage terminal connected to the second voltage line, and a ground terminal connected to the neutral line.

A vehicle includes: an on-board inverter that adjusts the voltage of an electric power; and a vehicle inlet. The vehicle inlet has a CS terminal through which a proximity detection signal for identifying the connection state between a discharge connector and the vehicle inlet is transmitted. An electronic control unit (ECU) includes a processor that selects the voltage of an electric power output from the on-board inverter. When the proximity detection signal is in a first bound (a fourth range or a fifth range), the processor selects AC 100V, and when the proximity detection signal is in a second bound (a fifth range or a sixth range) at least partially different from the first bound, the processor selects AC 200V higher than AC 100V.
