Zusammenfassung:	To provide a control device of a power supply circuit which can determine the deterioration of a relay.SOLUTION: A control device 100 that controls a power supply circuit 200 including a battery 10, a first relay 20A, and a second relay 20B executes sequence processing that energizes the second relay 20B after energizing the first relay 20A, processing of measuring an elapsed time from the energizing of the second relay 20B by executing the sequence processing until a voltage of a load 300 starts to increase, and processing of determining that the second relay 20B deteriorates when a determination condition including a condition in which the elapsed time is equal to or longer than a specified determination value is satisfied.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を通電状態にした後に第２リレー２０Ｂを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が通電状態にされてから負荷３００の電圧が増加し始めるまでの経過時間を計測する処理と、その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２リレー２０Ｂに劣化有りと判定する処理とを実行する。【選択図】図１
