VEHICLE BACKUP APPARATUS

There is provided a vehicle backup apparatus that easily supplies sufficient power to a load when supplying of power from a power supply unit has entered a failure state. In a vehicle power supplying system including a power supply unit that supplies power to a load, a vehicle backup apparatus performs a backup operation when the supplying of power from the power supply unit is in a failure state. The vehicle backup apparatus includes a charging/discharging unit for performing charging and discharging of a backup power supply that includes a battery and a capacitor and is a different power source to the power supply unit; and a control unit for controlling the charging/discharging unit. When the failure state has been entered, the control unit causes the charging/discharging unit to perform the backup operation so as to supply power based on the battery and the capacitor to the load.
