The invention discloses a bilaterally-driven battery charging relay safety control system and method. The system comprises an electric driving control module BMS, a vehicle control module VCU, a relay, a battery pack and a charging pile, wherein the charging pile provides a power supply for charging the battery pack; the relay realizes the on-off of the charging circuit; the electric driving control module BMS and the vehicle control module VCU are connected to the two ends of the relay correspondingly so as to achieve bilateral driving of the relay; and when the battery pack has an overcharge fault, the relay is cut off through the electric driving control module BMS or the vehicle control module VCU so as to stop charging. The safety performance of the relay in the charging process of the new energy automobile is improved. While the safety performance of the relay is improved, the scheme of the invention rarely changes the wire harness of the battery pack, only one wire harness is additionally arranged, and only one driving channel of the VCU is occupied, so that the change cost is low.

    本发明公开一种双边驱动的电池充电继电器安全控制系统及方法,其系统包括电驱控制模块BMS、整车控制模块VCU、继电器、电池包、充电桩;所述充电桩为电池包充电提供电源;所述继电器实现充电电路的通断;所述电驱控制模块BMS与整车控制模块VCU分别连接于继电器的两端,以对继电器实现双边驱动;当电池包发生过充故障时,通过所述电驱控制模块BMS或整车控制模块VCU切断继电器,以停止充电。本发明提升了新能源汽车充电过程中继电器的安全性能。且在提升继电器安全性能的同时,本发明的方案对于电池包线束的更改较少,仅增加了一条线束,并仅占用VCU一个驱动通道,更改成本低。
