Abstract
An output voltage obtaining unit receives information from an external charging facility and obtains a maximum output voltage of the external charging facility from that information. An upper limit voltage calculator calculates a battery voltage which is an inter-terminal voltage at the time of end of charging of a battery. A switching unit receives a result of comparison from a comparator. When relation of Vc≥VBu is satisfied in the result of comparison, the switching unit switches a charging relay to connect a DC inlet to a power line and a power line. When relation of Vc<VBu is satisfied, the switching unit switches the charging relay to connect the DC inlet to a bypass power line and a bypass power line.
