The invention provides a national standard-to-European standard charging communication protocol conversion control system and method. The system comprises a charging base, a BMS, a battery pack and an EVCC. The EVCC comprises a PP signal interface, a CP, a PE signal interface, an A + wake-up signal interface, a CC2 signal interface and a CAN communication signal interface. After the first interaction between the EVCC and the BMS is carried out to the BCP stage, the vehicle end battery voltage is obtained in advance, and in the second interaction stage or the re-interaction stage, the EVCC starts to be pre-charged when receiving a BRM message; and if the vehicle has the capability of detecting the voltage outside the contactor, judging the voltage difference between the voltage outside the contactor and the voltage of the battery after receiving CTS and CML messages. The national standard electric vehicle BMS can directly use the standard GB/T 27930 protocol to carry out CAN communication with the EVCC, so that the national standard electric vehicle BMS is minimum in modification, the European standard charging standard is met conveniently and quickly, and the method has the advantages of being high in practicability and compatibility.

    本发明提供了一种国标转欧标充电通信协议转换控制系统及方法,包括充电座、BMS、电池组和EVCC;EVCC包括PP信号接口,CP、PE信号接口,A+唤醒信号接口,CC2信号接口,CAN通信信号接口;EVCC与BMS第一次交互进行到BCP阶段后,提前获得车端电池电压,第二次或者重新交互阶段,EVCC收到BRM报文时开始预充;若车辆具备接触器外侧电压检测能力,收到CTS和CML报文后判断接触器外侧电压与电池电压压差。本发明实现国标电动车BMS可直接使用标准的GB/T 27930协议与EVCC进行CAN通信,使得国标电动车BMS修改最小,方便、快捷的符合欧标充电标准,具有可实施性强、兼容性高优势。
