To more properly manage a power storage element used to start an engine of a motorcycle on the basis of an internal resistance value.SOLUTION: A BMU (battery management unit) 101 of a secondary battery 62 (power storage element) used to start an engine of a motorcycle 10 comprises a voltage sensor 110 measuring a voltage value of the secondary battery 62, and a management unit 130. When the engine of the motorcycle 10 is not started, the management unit 130 measures a voltage value in time series by the voltage sensor 110, and estimates an internal resistance value of the secondary battery 62 on the basis of a difference between measured voltage values.SELECTED DRAWING: Figure 6

【課題】自動二輪車のエンジン始動に用いられる蓄電素子を内部抵抗値に基づいてより適切に管理すること。【解決手段】自動二輪車１０のエンジン始動に用いられる二次電池６２（蓄電素子）のＢＭＵ１０１（管理装置）であって、二次電池６２の電圧値を計測する電圧センサ１１０と、管理部１３０と、を備え、管理部１３０は、自動二輪車１０のエンジン始動時以外の時に電圧センサ１１０によって電圧値を時系列で計測し、計測した電圧値の差に基づいて二次電池６２の内部抵抗値を推定する。【選択図】図６
