The invention discloses an electric vehicle DC charging control circuit forward compatibility method, circuit and converter. Equivalent resistors are arranged on a CC1 loop or/and a CC2 loop, the typeof a charger is judged by monitoring the voltage on a CC2 line on the electric vehicle side, the charging process is carried out according to the type of the charger, and the charging efficiency is improved by monitoring the voltage on the CC1 line on the charger side. Whether the charger is reliably connected and allows safe charging or not is determined, so that the electric vehicle can be charged with all common chargers on the market, and forward compatibility of the direct-current charging control guide circuit is realized.
本发明公开了一种电动车直流充电控制电路向前兼容方法、电路及转换器,本发明在CC1回路或/和CC2回路上设置等效电阻,在电动车侧,通过监控CC2线上的电压,判断充电机类型,根据充电机类型进行充电流程,在充电机侧,通过监控CC1线上的电压,确定充电机是否可靠连接允许安全充电,使电动车可与市场上所有常见的充电机进行充电,实现了直流充电控制导引电路的向前兼容。
