PROBLEM TO BE SOLVED: To provide a power supply capable of determining a failure of an opening/closing element without providing a dedicated discharge circuit.SOLUTION: The power supply includes: a capacitor connected to a charging time output terminal of a charge/discharge circuit; a voltage detection part for detecting voltage of the charging time output terminal; a control part for controlling to open/close an opening/closing element interposed in an electric path between the charging time output terminal and a storage battery; and a determination part for determining a failure of the opening/closing element on the basis of voltage detected by the voltage detection part when the control part controls the opening/closing element from close to open and the charge/discharge circuit is operated.SELECTED DRAWING: Figure 1
【課題】専用の放電回路を設けることなく開閉素子の故障を判定することができる電源装置を提供する。【解決手段】電源装置は、充放電回路の充電時出力端子に接続されたキャパシタと、充電時出力端子の電圧を検出する電圧検出部と、充電時出力端子と蓄電池との間の電路に介装された開閉素子の開閉を制御する制御部と、制御部が開閉素子を閉から開へ制御した場合に、充放電回路を動作させたときに、電圧検出部で検出した電圧に基づいて開閉素子の故障を判定する判定部とを備える。【選択図】図1
