If an external power supply (400) is not connected to an electrically powered vehicle (100) by a charging cable and there is a request to output electric power from an AC receptacle (120), a power generation mode is selected and a charger (200) receives electric power from a main battery (10), converts it into alternating current electric power, and outputs it to a power line (151). In the power generation mode when an auxiliary machinery system is fed with electric power one of a first mode (a normal mode) and a second mode (a high-output mode) is selected depending on electric power used at the AC receptacle (120). In the normal mode, a main DC/DC converter (60) is stopped, while an AC/DC converter (170) is operated to generate auxiliary electric power. This allows reduced loss and hence higher efficiency. In the high-output mode, the main DC/DC converter (60) is operated to generate auxiliary electric power, while the AC/DC converter (170) is stopped. This allows electric power larger than in the normal mode to be output from the AC receptacle (120). |
