The invention provides an electric vehicle charging method and device based on the temperature of a charging port and an electric vehicle. The method comprises the steps that under the condition that a vehicle-mounted charger detects that a charging gun is inserted into a charging port of the electric vehicle, parking of the electric vehicle is controlled through an electronic parking system, and the vehicle-mounted charger, the electronic parking system and a vehicle body controller are all arranged on the electric vehicle; under the condition that the electric vehicle is parked, whether the electric vehicle is allowed to be charged or not is judged; when it is judged that the electric vehicle is allowed to be charged, the temperature of a charging port is detected through a temperature sensor arranged on the charging port, and the current limiting value of each charging stage is determined based on the temperature of the charging port; performing multi-step charging including a plurality of charging stages on the electric vehicle according to the current limit value of each charging stage; and detecting and judging whether the electric vehicle is charged or not in real time through the vehicle body controller. By adopting the technical means, the problem that potential safety hazards exist in charging of the electric vehicle in the prior art is solved.

    本申请提供了一种基于充电口温度的电动汽车充电方法、装置及电动汽车。该方法包括:在通过车载充电机检测到充电枪插入电动汽车的充电口的情况下,通过电子驻车系统控制电动汽车驻车,其中,车载充电机、电子驻车系统和车身控制器均设置在电动汽车上;在电动汽车驻车的情况下,判断电动汽车是否被允许充电;当判断电动汽车被允许充电,通过充电口上设置的温度传感器检测充电口温度,并基于充电口温度确定每个充电阶段的电流限值;按照每个充电阶段的电流限值对电动汽车进行包含多个充电阶段的多阶梯充电;通过车身控制器实时检测并判断电动汽车是否充电完成。本申请采用上述技术手段,解决了现有技术中电动汽车充电存在安全隐患的问题。
