Although a wet charging head will not cause a short circuit in the charging head itself, considering the safety of charging, it is forbidden to insert a wet charging head into the charging port on the car. Only when the water on the charging head is wiped clean or dried naturally Only then can it be inserted into the charging port on the car to ensure charging safety, resulting in low charging efficiency

The invention belongs to the field of electric automobile charging interfaces, and particularly relates to a safe charging interface for an electric automobile, which comprises a plug mechanism and a socket mechanism, wherein the plug mechanism connected with a power supply through a cable is in plug-in fit with the socket mechanism mounted on the automobile; A water film existing between the male head mechanism and the female head mechanism which are mutually plugged is extracted through the vacuum pump installed in the socket mechanism, so that safe charging of the electric automobile is not influenced by water accumulated on the ground when the plug mechanism falls into the socket mechanism of the electric automobile in the plugging process of the plug mechanism into the socket mechanism of the electric automobile. Therefore, the charging safety of the electric automobile under the condition that the plug mechanism is wet is improved, and meanwhile, the charging efficiency of the electric automobile under the condition that the plug mechanism is wet is improved.
Description
technical field [0001] The invention belongs to the field of charging interfaces for electric vehicles, in particular to a safe charging interface for electric vehicles. Background technique [0002] An electric vehicle (BEV) refers to a vehicle that is powered by a vehicle-mounted power supply, drives the wheels with a motor, and meets the requirements of road traffic and safety regulations. Due to its smaller impact on the environment than traditional cars, its prospects are widely optimistic. Working principle: battery - current - power regulator - electric motor - power transmission system - driving the car (Road). [0003] The driving power of electric vehicles does not emit harmful gases that pollute the atmosphere. Even if the power consumption is converted to power plant emissions, except for sulfur and particles, other pollutants are also significantly reduced. [0004] Electric vehicles are charged through charging piles, and the installation locations and instal...
