Charger and vehicle

A charger comprising:

• a bidirectional converter;
• a DC port that electrically connects the charger to a power storage device;
• a first AC port that receives first AC power for charging the power storage device;
• and
• a second AC port that outputs second AC power, wherein the bidirectional converter
• converts the first AC power into DC power and outputs the DC power to the DC port, and
• converts DC power supplied from the power storage device to the DC port into the second AC power and outputs the second AC power to the second AC port,
• the charger further comprising:
• a switching device including at least one switching relay that selectively switches between a first power path and a second power path, the first power path connecting the bidirectional converter and the first AC port, the second power path connecting the bidirectional converter and the second AC port;
• and
• an electric resistance connected in parallel to a position that bypasses a switching relay on the first power path, of the at least one switching relay.
