PROBLEM TO BE SOLVED: To provide a configuration to perform correct determination in a short time concerning disconnection of a connection terminal in a battery state detection device for detecting a state of a battery.SOLUTION: A battery state detection device 2 includes a current detection section 11a, a voltage detection section 11b, and an estimation section 11c. The current detection section 11a detects a battery current being the current to be input to a battery 10 or the current to be output from the battery 10. The voltage detection section 11b detects a terminal voltage of the battery 10 as a battery voltage. The estimation section 11c estimates whether a connection terminal is disconnected and which one of connection terminals is disconnected when the connection terminal is disconnected on the basis of both of a battery current detected by the current detection section 11a and a battery voltage detected by the voltage detection section 11b.SELECTED DRAWING: Figure 1

    【課題】バッテリーの状態を検出するバッテリー状態検出装置において、接続端子の外れについて短時間で正確な判定を行う構成を提供する。【解決手段】バッテリー状態検出装置2は、電流検出部11aと、電圧検出部11bと、推定部11cと、を備える。電流検出部11aは、バッテリー10に入力される電流又は当該バッテリー10から出力される電流であるバッテリー電流を検出する。電圧検出部11bは、バッテリー10の端子電圧をバッテリー電圧として検出する。推定部11cは、電流検出部11aが検出したバッテリー電流と、電圧検出部11bが検出したバッテリー電圧と、の両方に基づいて、接続端子が外れたか否か、及び、接続端子が外れた場合にどの接続端子が外れたかを推定する。【選択図】図1
