二次电池状态检测装置以及二次电池状态检测方法
摘要：
即使是在进行了绕过电流传感器的非正规的充放电的情况下，也正确地检测二次电池的状态。检测搭载于车辆的二次电池的状态的二次电池状态检测装置，包含：检测流过二次电池的电流的电流检测单元（电流传感器12），检测二次电池的电压的电压检测单元（电压传感器11），和判定单元（控制部10），该判定单元（控制部10）在对二次电池的端子直接连接外部设备，不经由电流检测单元，使二次电池充电或者放电了的情况下，基于由电流检测单元以及电压检测单元检测的电流值与电压值的变化判定如此的非正规的充放电是否发生。
摘要（英）：

The purpose of the invention is to accurately detect the state of a secondary battery even when non-normal charge and discharge that bypass a current sensor are performed. A secondary battery state detection device for detecting the state of a secondary battery mounted on a vehicle has: a current detection means (current sensor (12)) for detecting current flowing through the secondary battery; a voltage detection means (voltage sensor (11)) for detecting the voltage of the secondary battery; and a determination means (control unit (10)) for, when an external device is directly connected to the terminals of the secondary battery and the secondary battery is charged or discharged without using a path passing the current detection means, determining the presence or absence of the occurrence of such non-normal charge and discharge on the basis of the current and voltage value changes detected by the current detection means and the voltage detection means.
