PROBLEM TO BE SOLVED: To make disconnection of a switch faster than the conventional one.SOLUTION: A power supply controller controlling a power supply device that supplies power of a battery pack to an inverter via a main contactor and a sub contactor opened/closed by applying driving currents S3, S6 to exciting coils L1, L2 includes driving circuits 9A, 9B that supply the driving currents S3, S6 to the exciting coils L1, L2, and a battery ECU that detects an overvoltage of the battery pack, and on the basis of this detection result, generates first control signals S1, S4 and second control signals S2, S5 to be supplied to the driving circuits 9A, 9B. The driving circuits 9A, 9B include a drive transistor 9c that switches between application and non-application of the driving currents by opening/closing on the basis of the first control signals S1, S4, and a power consumption circuit C that consumes counter electromotive forces of the exciting coils L1, L2 on the basis of the second control signals S2, S5.SELECTED DRAWING: Figure 2

    【課題】開閉器の開放を従来よりも高速化する。【解決手段】励磁コイルL1、L2への駆動電流S3、S6の通電によって開閉するメインコンタクタ及びサブコンタクタを介して組電池の電力をインバータに供給する電源装置を制御する電源制御装置であって、駆動電流S3、S6を励磁コイルL1、L2に供給する駆動回路9A、9Bと、組電池の過電圧を検出し、この検出結果に基づいて駆動回路9A、9Bに供給する第1の制御信号S1、S4及び第2の制御信号S2、S5を生成するバッテリECUとを備え、駆動回路9A、9Bは、第1の制御信号S1、S4に基づいて開閉することによって駆動電流の通電/非通電を切替える駆動トランジスタ9cと、第2の制御信号S2、S5に基づいて励磁コイルL1、L2の逆起電力を消費する電力消費回路Cとを備える。【選択図】図2
