Zusammenfassung:	To provide a battery state determination system, a battery state determination device, a battery state determination method, a battery state determination program, and a storage medium, which enhance the accuracy of computing the internal resistance of a rechargeable battery.SOLUTION: A battery state determination system 8 disclosed herein comprises a controller 14 configured to determine if a rechargeable battery 2 is being charged or discharged. The controller 14 is capable of separately deriving a charging resistance value RC of the rechargeable battery 2 while charging and a discharge resistance value RD while discharging.SELECTED DRAWING: Figure 1 【課題】充電可能バッテリの内部抵抗の算出精度を高めることができるバッテリ状態判定システム、バッテリ状態判定装置、バッテリ状態判定方法、バッテリ状態判定プログラム、および記憶媒体を提供する。【解決手段】バッテリ状態システム８は、充電可能バッテリ２が充電中であるか放電中であるか判定するように構成されるコントローラ１４を備える。コントローラ１４は、充電可能バッテリ２の充電時の充電抵抗値ＲＣと放電時の放電抵抗値ＲＤとを別々に算出可能となるように構成される。【選択図】図１
