PROBLEM TO BE SOLVED: To provide a storage battery control device capable of providing guarantee both for use of a storage battery within a specified period and for sufficient utilization of the storage battery, without giving discomfort to a user.SOLUTION: A storage battery control device for an electric vehicle includes a storage battery 103 containing a plurality of batteries, and a motor 101 capable of supplying/receiving electric power from the storage battery 103. There are provided a degradation degree derivation part which derives a degradation degree of the storage battery 103 based on at least one of a charge/discharge history of the storage battery 103 and a temperature history of the storage battery 103, and a limit value derivation part which derives a limit value for at least one of output and capacity of the storage battery 103 based on the degradation degree.

    【課題】ユーザに違和感を与えることなく、規定期間内の蓄電池の使用の保証と蓄電池の十分な活用とを両立することが可能な蓄電池制御装置を提供する。【解決手段】複数のバッテリを有する蓄電池103と、蓄電池103との間で電力の授受が可能な電動機101と、を備える電動車両の蓄電池制御装置は、蓄電池103の充放電履歴および蓄電池103の温度履歴の少なくともいずれかに基づき、蓄電池103の劣化度合を導出する劣化度合導出部と、前記劣化度合に基づき、蓄電池103の出力および容量の少なくともいずれかの制限値を導出する制限値導出部と、を備える。【選択図】図3
