To provide a technique of more appropriately supplying a power to a plurality of loads at the time of a backup operation using a power storage part.SOLUTION: An on-vehicle backup control device 1 includes: a discharge circuit that performs a discharge of a power storage part 70; and a control part 40 that controls the discharge circuit. The control part 40 sets, as a disconnection threshold value, either of an overlap-enabled voltage defined as a voltage condition of the power storage part 70 as of when power is supplied simultaneously to a plurality of objective loads in an abnormal state, or a supply completion voltage defined in association with one of the plurality of objective loads. In the abnormal state, under a condition that a charging voltage of the power storage part 70 reaches to the disconnection threshold value or less, the control part 40 disconnects or delays power supply to any one of the plurality of objective loads, and prohibits simultaneous operation of the plurality of objective loads.SELECTED DRAWING: Figure 1

    【課題】蓄電部を利用したバックアップ動作時に、複数の負荷に対してより適切に電力を供給し得る技術を提供する。【解決手段】車載用のバックアップ制御装置1は、蓄電部70の放電を行う放電回路と、放電回路を制御する制御部40と、を有する。制御部40は、異常状態のときに複数の対象負荷に同時に電力を供給する場合の蓄電部70の電圧条件として定められる重畳可能電圧又は複数の対象負荷のいずれかに対応付けて定められる供給完了電圧のうちいずれかを遮断閾値として設定する。制御部40は、異常状態において蓄電部70の充電電圧が遮断閾値以下に達したことを条件として、複数の対象負荷のいずれかへの電力の供給を遮断又は遅延し複数の対象負荷の同時動作を禁止する。【選択図】図1
