To prevent a state of a power storage element from deviating from a range convenient for the power storage element.SOLUTION: A BMU 101 (a management device) of a secondary battery 62 (a power storage element) used for starting the engine of a motorcycle 10 includes a circuit breaker 55 connected in series with the secondary battery 62 and a management unit 130. When an SOC of the secondary battery 62 deviates from a plateau region (a predetermined range), the management unit 130 turns off (opens) the circuit breaker 55.SELECTED DRAWING: Figure 7 【課題】蓄電素子の状態が蓄電素子にとって都合のよい範囲から外れることを抑制すること。【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と直列に接続されている遮断器５５と、管理部１３０と、を備え、管理部１３０は、二次電池６２のＳＯＣがプラトー領域（所定の範囲）から外れると遮断器５５をオフ（開、オープン）にする。【選択図】図７
