The invention relates to an alternating current charging control method for an electric vehicle, which comprises the following steps that: 1) when the charging process is abnormal, a vehicle control device controls to stop charging, and a whole vehicle system enters dormancy; (2) a voltage monitoring unit integrated in the vehicle control device monitors whether the CP end returns to normal or not; if so, turning to the step 4); otherwise, turning to step 3); (3) the vehicle control device keeps dormancy, and the step (2) is executed; (4) the voltage monitoring unit awakens the vehicle control device; 5) the vehicle control device detects whether the charging plug is normally connected; if the connection is normal, turning to step 7); (6) the vehicle control device enters a dormancy state and turns to the step (2), (7) the vehicle control device wakes up a whole vehicle system, (8) a vehicle-mounted charger detects whether an input undervoltage fault exists or not, if no input undervoltage exists, the step (9) is turned to, and if not, the step (1) is turned to, and (9) the whole vehicle system enters a charging working state.

    本发明涉及一种电动车交流充电控制方法,包括:1)充电过程中异常时,车辆控制装置控制停止充电,整车系统进入休眠;2)车辆控制装置中集成的电压监测单元监测CP端是否恢复正常;如恢复正常,转入步骤4);否则转入步骤3);3)车辆控制装置保持休眠,转入步骤2);4)电压监测单元唤醒车辆控制装置;5)车辆控制装置检测充电插头是否正常连接;如正常连接,转入步骤7);否则转入步骤6);6)车辆控制装置进入休眠,转入步骤2);7)车辆控制装置唤醒整车系统;8)车载充电机检测是否存在输入欠压故障;无输入欠压,转入步骤9);否则转入步骤1);9)整车系统进入充电工作状态。电动车在异常恢复后可继续自动充电,更安全。
