Charge efficiency of normal charge is improved without restricting an operation of a low-voltage load of an electric vehicle during the normal charge. During a charge of a high-voltage battery of a vehicle, when a determination of the normal charge is made, and when a determination that a mode switching target load is not operated is made, power saving mode transition processing is performed. Therefore, an operating mode of a DC-DC converter, which steps down a voltage at the high-voltage battery and supplies the stepped-down voltage to a low-voltage battery and a low-voltage load, is set to a power saving mode in which consumption power is reduced compared with a normal mode. When a determination that a start-up manipulation of the mode switching target load is performed is made, the operating mode of the DC-DC converter is changed to the normal mode.
A power conversion apparatus comprising:
A power control method performed by a power conversion apparatus, which includes a switching element that is driven to step down a voltage of a first battery for running an electric vehicle, the stepped-down voltage being supplied to a second battery and a plurality of loads, the power control method comprising:
