To provide an energization control device in which a cutoff can be performed even when an abnormality occurs in any part outside terminals.SOLUTION: An energization control device 13 includes at least three terminals 121, 122 and 123 that are connected to the outside, switches SW100 (SW101, SW102) that are provided on a main current path 130 connecting the terminals to each other and that each perform switching between conduction and cutoff between the terminals, and a controller 150. The controller 150 detects current flowing through each of the switches, and determines whether or not overcurrent due to an abnormality is flowing. When the current flowing through at least one of the switches is overcurrent, the controller 150 switches a switch that is connected to the terminal closest to the abnormal site, to an off state on the basis of the flowing direction of the overcurrent.SELECTED DRAWING: Figure 18

    【課題】端子外のいずれに異常が生じた場合でも、遮断することができる通電制御装置を提供すること。【解決手段】通電制御装置13は、外部と接続される3つ以上の端子121、122、123と、異なる端子間をつなぐ電流の主経路130に設けられ、端子間の導通及び遮断を切り替えるスイッチSW100(SW101、SW102)と、コントローラ150を備える。コントローラ150は、複数のスイッチのそれぞれに流れる電流を検出し、異常にともなう過電流が流れているか否かを判定する。コントローラ150は、少なくとも一部のスイッチに流れる電流が過電流である場合に、過電流が流れる向きに基づいて、異常の部位にもっとも近い端子に接続されたスイッチをオフ状態に切り替える。【選択図】図18
