Zusammenfassung:	To detect an anomaly of a built-in sensor.SOLUTION: A storage battery unit includes: a chargeable/dischargeable battery cell; a current sensor that detects a current flowing through the battery cell; a voltage sensor that detects the voltage of the battery cell; and an anomaly detection processing section that detects an anomaly of the current sensor or the voltage sensor on the basis of an amount of change between a first voltage value detected by the voltage sensor in a state where the current sensor detects a predetermined specific current value and a second voltage value detected by the voltage sensor when a specified time has elapsed while the state is continued.SELECTED DRAWING: Figure 1 【課題】内蔵のセンサの異常を検出する。【解決手段】蓄電池ユニットは、充放電可能な電池セルと、前記電池セルを流れる電流を検出する電流センサと、前記電池セルの電圧を検出する電圧センサと、前記電流センサが予め定めらえた特定の電流値を検出した状態において、前記電圧センサが検出した第１電圧値と、当該状態を継続したまま規定時間経過した際に、前記電圧センサが検出した第２電圧値との変化量に基づいて、前記電流センサ又は前記電圧センサの異常を検出する異常検出処理部とを備える。【選択図】図１
