PROBLEM TO BE SOLVED: To achieve a backup device for a vehicle, which can back up a plurality of driving sources by the supply of electric power from a second electric power supply part even if the supply of electric power from a first electric power supply part stops, and can effectively reduce the peak current necessary for backup operation.SOLUTION: In a backup device 1, a control part 5 instructs a discharge part 2 to intermittently send a discharge current plural times to each of a plurality of motors 122A, 122B when detecting an abnormal condition of the supply of electric power from a first electric power supply part 91, and controls the supply destination of the discharge current such that each instruction time for instructing the discharge part 2 to send the discharge current to one motor 122A is staggered from each instruction time for instructing the discharge part 2 to send the discharge current to the other motor 122B.SELECTED DRAWING: Figure 2
【課題】第1電源部からの電力供給が途絶えた場合でも第2電源部からの電力供給によって複数の駆動源をバックアップすることができ、且つバックアップ動作時に必要なピーク電流を効果的に低減し得る車両用のバックアップ装置を実現する。【解決手段】バックアップ装置1において、制御部5は、第1電源部91からの電力供給の異常状態を検出した場合に放電部2に対して複数のモータ122A,122Bの各々に放電電流を複数回断続的に流すことを指示し、且つ一方のモータ122Aに放電電流を流すことを放電部2に指示する各指示時間を、他方のモータ122Bに放電電流を流すことを放電部2に指示する各指示時間からずらすように放電電流の供給先を制御する。【選択図】図2
