To provide an energization control device in which an ON failure of a switch can be confirmed during an energization time period.SOLUTION: An energization control device includes a first terminal that is connected to a first power supply side bus, a second terminal that is connected to a second power supply side bus, a plurality of switches that are disposed in parallel between the terminals, a control unit that controls driving of the switches, and a determination unit that determines whether or not an ON failure has occurred in the switches. During the time period of energization between the first terminal and the second terminal, the control unit temporarily switches the control to a failure detection control so as to keep the ON state of a first switch of the plurality of switches, and to adjust the resistance value of a second switch, which is the remaining switch, to be higher than that during the ON state. The determination unit determines whether or not an on failure has occurred in the second switch on the basis of the fluctuation of a physical quantity caused by the fluctuations of the resistance values.SELECTED DRAWING: Figure 4

    【課題】通電期間にスイッチのオン故障を確認できる通電制御装置を提供すること【解決手段】通電制御装置は、第1電源側のバスと接続される第1端子、第2電源側のバスと接続される第2端子、端子間で並列に設けられた複数のスイッチ、スイッチの駆動を制御する制御部、及びスイッチにオン故障が生じているか否かを判定する判定部を備えている。制御部は、第1端子と第2端子との通電期間において、複数のスイッチの一部である第1スイッチのオン状態を保持し、残りのスイッチである第2スイッチの抵抗値がオン状態よりも高くなるように故障検出制御に一時的に切り替える。判定部は、抵抗値の変化にともなう物理量の変化に基づいて、第2スイッチにオン故障が生じているか否かを判定する。【選択図】図4
