The invention relates to an electric vehicle charging control method and circuit, a charging device and a storage medium. The method comprises the following steps: detecting whether the charging device obtains direct-current input voltage; if the direct-current input voltage is obtained, the charging device is started to charge a vehicle battery; and carrying out charging monitoring on the charging process to obtain a charging current, and if the charging current reaches a preset current value, stopping charging by the charging device. Whether the DC input voltage exists or not is detected before charging, and then whether the charging device is started for charging or not is determined; real-time monitoring is carried out in the charging process, charging is cut off in time when the charging current reaches the preset current value, battery explosion, battery life damage and electric quantity waste caused by long-time charging after the battery is fully charged are avoided based on multi-layer charging protection, and the charging safety of the electric vehicle battery is improved.

    本申请涉及电动车充电控制方法、控制电路、充电装置及存储介质。方法包括:检测充电装置是否获取到直流输入电压;若获取到直流输入电压,则充电装置开启对车辆电池进行充电;对充电过程进行充电监测,获取充电电流,若充电电流达到预设电流值,则充电装置关断充电。本申请通过在充电前先检测是否存在直流输入电压后再确定是否开启充电装置进行充电;在充电过程中进行实时监测,当充电电流达到预设电流值时及时断开充电,基于多层充电保护,避免电池充满之后长时间充电导致的电池爆炸、电池寿命受损以及电量浪费,提高了电动车电池充电的安全性。
