Charging device

A charging device comprising:

• an input port that is electrically connected to an external power source provided externally and that is configured to be able to input direct-current power and alternating-current power from the external power source;
• an output port that is electrically connected to an electrified vehicle and that outputs direct-current power to the electrified vehicle, the output port is configured to be able to also output alternating-current power to the electrified vehicle;
• and
• a relay circuit that relays power between the input port and the output port, wherein the relay circuit includes:
• a converter circuit that converts alternating-current power into direct-current power when the alternating-current power is input to the input port,
• an input bypass circuit that causes direct-current power to bypass the converter circuit when the direct-current power is input to the input port,
• an inverter circuit that converts direct-current power into alternating-current power when the alternating-current power is output to the electrified vehicle, and
• an output bypass circuit that causes direct-current power to bypass the inverter circuit when the direct-current power is output to the electrified vehicle.

• a second input switch that switches between the converter circuit and the input bypass circuit, and
• an input information receiving unit that receives, from the external power source, input information indicating whether power input from the external power source to the input port is direct-current power or alternating-current power, and
• wherein the second input switch switches between the converter circuit and the input bypass circuit based on the input information received by the input information receiving unit.
