    • Disclosed is a battery pack management method for HEV and EV. The method comprises steps of: applying power for a control signal to a relay of a battery pack connection circuit through a battery management system (BMS) or vehicle control device; detecting current or voltage from a pre-charge resistor of the battery pack connection circuit; comparing the detected current or voltage with standard correspondence information pre-stored in a memory unit of the BMS to determine whether the detected value is within a normal range of the battery pack; and carrying out a normal charging operation when the detected value is within the normal range as a result of the determination, otherwise turning off a pre-charge relay of the battery pack connection circuit and then providing a driver with a warning signal through warning means electrically connected to the BMS.
    • 公开了一种用于HEV和EV的电池组管理方法。 该方法包括以下步骤:通过电池管理系统(BMS)或车辆控制装置向电池组连接电路的继电器施加用于控制信号的电力; 从电池组连接电路的预充电电阻检测电流或电压; 将检测到的电流或电压与预先存储在BMS的存储器单元中的标准对应信息进行比较,以确定检测值是否在电池组的正常范围内; 并且当所述确定的结果检测值在所述正常范围内时执行正常的充电操作,否则关闭所述电池组连接电路的预充电继电器,然后通过电气警告装置向驾驶员提供警告信号 连接到BMS。
