To provide a vehicle battery management system that can quickly and appropriately perform maximum input and output even when a vehicle is changed.SOLUTION: A vehicle battery management system includes a first control unit 22Aa that controls the input/output of a first battery 10A that can be installed in a first vehicle 12A, a first acquisition unit 22Ab that continuously acquires usage trend information indicating a usage state of the first battery 10A that can be a cause of deterioration of the first battery 10A, a first accumulation processing unit 22Ac that accumulates the continuously acquired usage trend information in a first memory unit 22Af, a first restriction unit 22Ad that restricts the input/output of the first battery 10A in the first control unit 22Aa on the basis of the accumulated usage trend information such that the input/output falls within a battery deterioration suppression range, and a first transition unit 22Ae that transitions the accumulated usage trend information to a second restriction unit 22Bd that restricts the input/output of a second battery 10B of a second vehicle 12B different from the first vehicle 12A within the battery deterioration suppression range.SELECTED DRAWING: Figure 2
【課題】車両の乗り換えが行われる場合でも、迅速に適切な最大入出力を行うことができる車両用電池制御システムを提供する。【解決手段】車両用電池制御システムは、第1の車両12Aに搭載可能な第1の電池10Aの入出力を制御する第1の制御部22Aaと、第1の電池10Aの劣化の要因となり得る第1の電池10Aの利用状態を示す利用傾向情報を継続的に取得する第1の取得部22Abと、継続的に取得される利用傾向情報を第1の記憶部22Afに蓄積する第1の蓄積処理部22Acと、蓄積された利用傾向情報に基づいて第1の制御部22Aaにおける第1の電池10Aの入出力が電池劣化抑制範囲に収まるように制限する第1の制限部22Adと、蓄積した利用傾向情報を第1の車両12Aとは異なる第2の車両12Bの第2の電池10Bの入出力を電池劣化抑制範囲に制限する第2の制限部22Bdに移行させる第1の移行部22Aeと、を含む。【選択図】図2
