A backup device includes: a charging unit that charges a second power source unit on the basis of the power supply from a first power source unit; a voltage detection unit detects the output voltage of the second power source unit; a vehicle speed information acquisition unit acquires vehicle speed information; and a control unit sets, on the basis of at least the vehicle speed information acquired by the vehicle speed information acquisition unit, a charging target voltage according to a setting method in which the voltage is set higher as the vehicle speed indicated by the vehicle speed information is greater, and causes, on the basis of the output voltage of the second power source unit detected by the voltage detection unit, the charging unit to perform the charging operation so as to bring the output voltage of the second power source unit close to the charging target voltage.
