To provide a power supply device and an electric vehicle using the power supply device that can warm up each of a plurality of power storage devices while restraining occurrence of variation in the temperatures of the plurality of power storage devices, a control unit performs a warm-up control that increases a time ratio of the ON state of a switch element relating to one of the plurality of power storage devices in controlling the ratio of ON and OFF states of the switch element as compared to a time ratio of the ON state of a switch element relating to other power storage device when a temperature detected at the temperature detection unit relating to the one of the plurality of power storage devices is lower than a first temperature.
