However, the charging device for electric vehicles has not been widely used, and there are many problems in the conductive charging method generally used for electric vehicles. For example, the large charging current (especially in the fast charging mode) makes the connector very heavy and seriously affects the aesthetic appearance of the environment. For another example, when charging, the vehicle needs to be stopped first, and then the charging cable on the charger is connected to the charging interface of the electric vehicle, which makes the operation cumbersome and time and labor consuming. For another example, mechanical friction between the socket and the plug may cause poor contact after long-term use, affect charging effect, and easily generate electric sparks. Further, for example, in severe weather such as cable aging and rain and snow, in cases where the connector is forgotten to be removed after charging is completed, or in cases where the charging cable is inadvertently pulled, electrical leakage is likely to occur, which may lead to a safety accident.
In addition, the electric vehicle is limited by the current power battery technology development level, and the problems of large occupied space of the battery pack, short endurance mileage, long one-time charging time, frequent charging and the like exist.
