To detect abnormality of configuration for detecting a state of a secondary battery.SOLUTION: An abnormality diagnostic system comprises: a discharge control unit for controlling a switch of a discharge unit that discharges a secondary battery when the switch and a resistor element connected to the secondary battery is connected in series and the switch is turned on; a measuring unit for measuring a current flowing from the secondary battery and a voltage of the secondary battery; and a determination unit for determining abnormality of the discharge unit on the basis of a current value measured by the measuring unit when the switch is turned off and a current value measured by the measuring unit when the switch is turned on.SELECTED DRAWING: Figure 3 【課題】二次電池の状態を検知するための構成の異常を検知する。【解決手段】異常診断システムは、二次電池に接続されたスイッチと抵抗素子とが直列に接続されて前記スイッチがオンのときに前記二次電池を放電させる放電部の前記スイッチを制御する放電制御部と、前記二次電池から流れる電流と前記二次電池の電圧を測定する測定部と、前記スイッチがオフのときに前記測定部が測定した電流値と、前記スイッチがオンのときに前記測定部が測定した電流値に基づいて前記放電部の異常を判定する判定部と、を備える。【選択図】図３
