Abstract

An electric vehicle includes: a storage device configured to store power used for traveling; an auxiliary battery configured to store power supplied to an auxiliary load; a converter configured to charge the auxiliary battery by using power supplied from the storage device; and a shut-off device configured to switch between a supply condition in which power is supplied to the auxiliary load from the auxiliary battery and a shut-off condition in which power is not supplied to the auxiliary load from the auxiliary battery. During control of the electric vehicle, the converter is controlled such that an output voltage of the converter is higher when the shut-off device is in the shut-off condition than when the shut-off device is in the supply condition.
