Abstract
An inter-terminal voltage obtaining unit obtains an inter-terminal voltage of a battery. A comparator compares the inter-terminal voltage with a maximum output voltage of a charger. When relation of VB≤VCmax is satisfied, an AC charging relay is switched such that output electric power from the charger is supplied to a high-voltage side of a buck-boost converter. When relation of VB>VCmax is satisfied, the AC charging relay is switched such that an output voltage of the charger is supplied to a low-voltage side of the buck-boost converter and the buck-boost converter is activated.
