Provided is a technology that is able to set the charge voltage of an auxiliary power source to reflect the temperature state during a period in which the vehicle is stopped. A vehicular backup device includes a charge/discharge circuit, a temperature detection unit, and a control unit. The control unit causes the charge/discharge circuit to perform an operation such that the charge voltage of an auxiliary power source achieves a target voltage on condition that a start switch of the vehicle is ON. The control unit sets the target voltage based on the temperature detected by the temperature detection unit when the start switch is OFF.
