To provide a power source circuit control device in which deterioration of a relay can be determined.SOLUTION: A control device 100 for controlling a power source circuit 200 including a battery 10, a first relay 20A, and a second relay 20B, executes sequence processing of bringing the first relay 20A, the second relay 20B, and the third relay 20C in this order into a current flowing state, and then, bringing the second relay 20B into a non-current flowing state, processing of, when a voltage being supplied to a load 300 starts decreasing after the second relay 20B is brought into the non-current flowing state as a result of execution of the sequence processing, measuring an elapse time period from the decrease of the voltage to an increase of the voltage, and processing of determining that the third relay 20C is deteriorated when a determination condition including a condition that the measured elapse time period is equal to or greater than a prescribed determination value is established.SELECTED DRAWING: Figure 1

    【課題】リレーの劣化を判定することのできる電源回路の制御装置を提供する。【解決手段】バッテリ10と第1リレー20Aと第2リレー20Bとを含む電源回路200を制御する制御装置100は、第1リレー20A、第2リレー20B、第3リレー20Cの順に各リレーを通電状態にした後、第2リレー20Bを非通電状態にするシーケンス処理と、シーケンス処理の実行によって第2リレー20Bが非通電状態にされたときから負荷300に供給される電圧が低下し始めた場合には、当該電圧が低下し始めてから増大に転じるまでの経過時間を計測する処理と、その計測した経過時間が規定の判定値以上であるとの条件を含む判定条件が成立する場合には、第3リレー20Cに劣化有りと判定する処理とを実行する。【選択図】図1
