The invention discloses an electric vehicle, a charging control method and device thereof and a storage medium, and the method comprises the steps: determining the current charging stage of the electric vehicle, and the charging stage sequentially comprises a first stage, a second stage and a third stage according to the time sequence; in the first stage, the maximum request charging current of the electric vehicle is controlled to continuously rise; in the second stage, the first temperature rise rate of the charging port of the electric vehicle is obtained, and the maximum request charging current of the electric vehicle is determined according to the first temperature rise rate; and in the third stage, the temperature and the second temperature rise rate of the charging port of the electric vehicle are obtained, and the maximum requested charging current of the electric vehicle is determined according to the temperature and the second temperature rise rate. Therefore, on the premise that high charging efficiency is guaranteed, the temperature of the charging port of the electric vehicle in the whole charging process is kept within a reasonable range, and therefore the spontaneous combustion risk in the charging process of the electric vehicle is effectively reduced.

    本发明公开了一种电动汽车及其充电控制方法、装置及存储介质,其中方法包括:确定电动汽车当前所处充电阶段,充电阶段按照时间顺序依次包括第一阶段、第二阶段和第三阶段;在第一阶段,控制电动汽车的最大请求充电电流持续上升;在第二阶段,获取电动汽车的充电口的第一温升速率,并根据第一温升速率确定电动汽车的最大请求充电电流;在第三阶段,获取电动汽车的充电口的温度和第二温升速率,并根据温度和第二温升速率确定电动汽车的最大请求充电电流。由此,能够在保证较高充电效率的前提下,使得整个充电过程中电动汽车的充电口温度维持在一个合理的范围内,从而有效降低电动汽车充电过程中的自燃风险。
