An electric separation circuit of charging and discharging interfaces is disclosed, and comprises a charging interface ACL1, a charging interface ACN1, a discharging interface ACL2, a discharging interface ACN2 and a power interface, and also includes a digital signal processor, a first relay K1, a second relay K2 and a switch control module. The first relay K1 and the second relay K2 are single-pole double-throw relays. The digital signal processor is connected to the input terminal of the switch control module. The input terminals of the first relay K1 and the second relay K2 are connected to an output terminal of the switch control module. The first contact pin of the first relay K1 is connected to the charging interface ACL1, and the second contact pin of the first relay K1 is connected to the discharging interface ACL2. The common connection end of the first relay K1 is connected to the power interface. Through the above means, the discharge interfaces are not turned on during charging and the charging interfaces are not turned on during discharging, which ensures the separation and independence of charging and discharging, and improves the safety of charging and discharging.

    本申请公开了一种充放电接口电气分离电路,包括充电接口ACL1、充电接口ACN1,放电接口ACL2、放电接口ACN2和电源接口,还包括数字信号处理器、第一继电器K1、第二继电器K2和开关控制模块,第一继电器K1、第二继电器K2均为单刀双掷继电器,数字信号处理器与所述开关控制模块的输入端连接,所述第一继电器K1的输入端、第二继电器K2的输入端均与开关控制模块的输出端连接,所述第一继电器K1的第一触点引脚与所述充电接口ACL1连接,所述第一继电器K1的第二触点引脚与所述放电接口ACL2连接,所述第一继电器K1的公共连接端与所述电源接口连接。通过上述手段,实现充电时放电接口未导通,放电时充电接口未导通,保障了充放电的分离与独立,提高了充放电的安全性。
