To suppress reduction of movable distance of a mobile object due to deterioration of a battery mounted on the mobile object when the battery is shared between a user of the mobile object and another user.SOLUTION: A battery management system 1 comprises: a battery capacity division unit 11 which virtually divides chargeable capacity of a battery 61 mounted on a mobile object 60 into a first area C1 and a second area C2 to allow use of the battery 61 in the first area C1 by a first user and use of the battery 61 in the second area C2 by a second user; a deterioration reduction amount estimation unit 12 which estimates a deterioration reduction amount as a reduction amount of the chargeable capacity of the battery 61 due to deterioration; and an allocation capacity adjustment unit 13 which reduces the chargeable capacity of the second area C2 by the deterioration reduction amount when the deterioration reduction amount is a first prescribed amount or less.SELECTED DRAWING: Figure 2
【課題】移動体に搭載されるバッテリを、移動体使用者と他使用者とにより共用する場合に、バッテリの劣化によって、移動体の移動可能距離が減少することを抑制する。【解決手段】バッテリ管理システム1は、移動体60に搭載されたバッテリ61の充電可能容量を第1領域C1と第2領域C2に仮想的に分割して、第1使用者による第1領域C1でのバッテリ61の使用と、第2使用者による第2領域C2でのバッテリ61の使用を可能にするバッテリ容量分割部11と、劣化によるバッテリ61の充電可能容量の減少量である劣化減少量を推定する劣化減少量推定部12と、劣化減少量が第1所定量以下である場合に、第2領域C2の充電可能容量を、劣化減少量分だけ減少させる割当容量調整部13と、を備える。【選択図】図2
