To provide an estimation system and an estimation program capable of improving estimation accuracy of the remaining amount of charge or deterioration of a battery.SOLUTION: A server device 4 that estimates the remaining amount of charge or deterioration of a battery 11 of a vehicle 1 includes at least: an acquisition unit 431 that acquires discharge current information indicating an actually measured current amount at the time of discharging the battery 11 and discharge voltage information indicating an actually measured voltage value at the time of discharging the battery 11; and an estimation unit 432 that estimates the remaining amount of charge or deterioration of the battery 11 based on the discharge current information and the discharge voltage information acquired by the acquisition unit 431. The estimation unit 432 calculates a discharge amount of the battery 11 based on the discharge current information and the discharge voltage information acquired by the acquisition unit 431 and estimates the remaining amount of charge of the battery 11 based on the calculated discharge amount of the battery 11 and an estimated full charge capacity estimated as the maximum charge capacity of the battery 11.SELECTED DRAWING: Figure 1

    【課題】バッテリの充電残量又は劣化の推定精度を向上させることを可能にする推定システム、及び推定プログラムを提供する事を目的とする。【解決手段】車両1のバッテリ11の充電残量又は劣化を推定するサーバ装置4であって、少なくとも、バッテリ11の放電時の実測電流量を示す放電時電流情報と、バッテリ11の放電時の実測電圧値を示す放電時電圧情報とを取得する取得部431と、取得部431が取得した放電時電流情報及び放電時電圧情報に基づいて、バッテリ11の充電残量又は劣化を推定する推定部432と、を備え、推定部432は、取得部431が取得した放電時電流情報及び放電時電圧情報に基づいてバッテリ11の放電量を演算し、演算されたバッテリ11の放電量と、バッテリ11の最大の充電容量であるものと推定される推定満充電容量とに基づいて、バッテリ11の充電残量を推定する。【選択図】図1
