The invention provides a charging method and a charging port device of an electric vehicle, and belongs to the technical field of electric vehicles. The charging method of the electric vehicle comprises the steps that when the electric vehicle starts to be charged, the rainfall capacity and the accumulated snow amount at a charging port are obtained; when the rainfall is larger than or equal to the first threshold value and smaller than the second threshold value, and/or the accumulated snow amount is greater than or equal to the third threshold value and smaller than the fourth threshold value, a first control instruction used for instructing a driver to send prompt information in a first mode is output; and when the rainfall is greater than or equal to the second threshold value and/or the accumulated snow amount is greater than or equal to the fourth threshold value, a second instruction used for indicating to stop charging the electric vehicle is output. The second threshold is greater than the first threshold, and the fourth threshold is greater than the third threshold. According to the method, the power-on condition of the charging port can be adjusted in real time according to the external extreme weather condition, and the service life of the charging port is prolonged.

    本发明提供了一种电动汽车的充电方法和充电口装置,属于电动汽车技术领域。该电动汽车的充电方法包括当开始对电动汽车充电时,获取降雨量和充电口处的积雪量。当降雨量大于或等于第一阈值且小于第二阈值,和/或积雪量大于或者等于第三阈值且小于第四阈值时,输出用于指示向驾驶员以第一方式发出提示信息的第一控制指令。当降雨量大于或等于第二阈值,和/或积雪量大于或等于第四阈值时,输出用于指示停止对所述电动汽车充电的第二指令。第二阈值大于第一阈值,第四阈值大于第三阈值。该方法能够根据外界的极端天气情况对充电口的通电情况进行实时调整,提高充电口的使用寿命。
