The invention discloses an European standard and national standard compatible alternating current charging method and system, and relates to the technical field of electric vehicle charging, and the method comprises the steps that a battery BMS determines to enter an European standard alternating current charging process or a national standard alternating current charging process based on a received first external signal; wherein the first external signal is an alternating current charging signal provided by an electric vehicle charging communication controller EVCC, a PP signal provided by a European standard alternating current charging pile or a gun insertion signal provided by a vehicle-mounted charger OBC; and/or the OBC determines to enter the European standard alternating current charging process or the national standard alternating current charging process based on the received signal provided by the national standard or European standard alternating current charging pile. No matter the European-standard AC charging pile or the national-standard AC charging pile is adopted, the type of the charging pile can be identified, and a corresponding charging process is entered, so that European-standard and national-standard compatible AC charging is realized.

    本发明公开了一种欧标国标兼容交流充电方法及系统,涉及电动汽车充电技术领域,该方法包括:电池BMS基于接收到的第一外部信号,来确定进入欧标交流充电流程或国标交流充电流程;其中,第一外部信号为电动汽车充电通讯控制器EVCC提供的交流充电信号、欧标交流充电桩提供的PP信号或车载充电机OBC提供的插枪信号;和/或,车载充电机OBC基于接收到的国标或欧标交流充电桩提供的信号,来确定进入欧标交流充电流程或国标交流充电流程。无论采用欧标交流充电桩还是国标交流充电桩,都可以识别出充电桩类型并进入对应的充电流程,从而实现欧标国标兼容交流充电。
