摘要：
Disclosed are a method and an apparatus for diagnosing an abnormality of a current-measuring unit for measuring the charging or discharging current of a battery pack. The method for diagnosing an abnormality of the current-measuring unit according to the present invention comprises the steps of: measuring the voltage and current of the battery pack; and comparing the voltage variation and the current variation measured during a predetermined time period with a voltage reference value and a current reference value, respectively, to diagnose an abnormality of the current-measuring unit. According to the present invention, the reliability of the battery pack is improved, and the battery pack is protected from dangerous conditions such as an explosion even when the current-measuring unit is broken down.
摘要（中）：
公开了一种用于诊断用于测量电池组的充电或放电电流的电流测量单元的异常的方法和设备。 根据本发明的用于诊断电流测量单元的异常的方法包括以下步骤：测量电池组的电压和电流; 以及将在预定时间段期间测量的电压变化和电流变化分别与电压参考值和电流参考值进行比较，以诊断电流测量单元的异常。 根据本发明，电池组的可靠性得到改善，并且即使在电流测量单元发生故障时，也能够保护电池组免受诸如爆炸之类的危险情况的影响。
