The invention provides a battery pack external controller and a battery pack. The battery pack external controller is used for controlling a battery pack. The battery pack comprises a battery module, an output end, an input end, a BMS acquisition board, a relay and a relay control circuit. The input end and the output end are respectively connected with the battery module, the BMS acquisition board is used for acquiring state information, the plurality of relays are respectively arranged between the input end and the battery module and between the output end and the battery module, and the relay control circuit is arranged between the BMS acquisition board and the plurality of relays so as to control the disconnection of a target relay according to the state information of the battery module; the battery pack external controller is connected with the BMS acquisition board and is used for receiving the state information and generating a disconnection command according to the state information so as to control the circuit to control the target relay to be disconnected; the battery pack external controller is further connected with the control ends of the relays and used for controlling the target relay to be disconnected through the control end of the target relay when the BMS collection board and/or the relay control circuit breaks down.

    本申请提供了一种电池包外部控制器及电池包。该电池包外部控制器用于控制电池包,电池包包括电池模组、输出端、输入端、BMS采集板、继电器以及继电器控制电路;输入端和输出端分别与电池模组连接,BMS采集板用于采集状态信息,多个继电器分别设置在输入端和输出端与电池模组之间,继电器控制电路设置在BMS采集板连与多个继电器之间,以根据电池模组的状态信息控制目标继电器的断开;电池包外部控制器与BMS采集板连接,用于接收状态信息,以及根据状态信息,生成断开命令,以控制电路控制目标继电器断开;电池包外部控制器还与多个继电器的控制端连接,用于当BMS采集板和/或继电器控制电路故障时,通过目标继电器的控制端控制目标继电器断开。
