Abstract:
1. An electrically-powered vehicle, comprising: first and second power storage devices being chargeable and dischargeable; a first power line provided in common for said first power storage device and an AC power supply external to said electrically-powered vehicle; a load device for receiving DC power to operate; a second power line for supplying DC power to said load device; a first power conversion unit for converting between DC power supplied to said second power line and one of AC power and DC power supplied to said first power line; a voltage conversion unit electrically connected to said second power storage device and said second power line; a first connection unit connected to said first power storage device and said first power line, and having a conducting state and a non-conducting state; a second connection unit connected to said first power storage device and said voltage conversion unit, and having a conducting state and a non-conducting state; and a control device for controlling at least said voltage conversion unit, said first connection unit and said second connection unit, when AC power is supplied to said first power line from outside said electrically-powered vehicle, said control device controlling said first connection unit to take the non-conducting state and said second connection unit to take the conducting state and controlling said voltage conversion unit such that a target voltage is supplied to said first and second power storage devices, based on a voltage value of DC power supplied to said second power line.
