Abstract

The invention discloses an electric vehicle charging station for resistance to water vapor corrosion. A humidity-dependent sensor module is installed on the outside of each charging pile. Thus, during the application process of the electric vehicle charging station, changes of humidity in the ambient environment can be detected, and the electric vehicle charging station is greatly protected. Sensitivity of the humidity-dependent sensor module is high, test repeatability is good, and an unexpected technical effect is generated. The electric vehicle charging station has a great market application prospect.

Description

technical field [0001] The invention belongs to the field of charging stations, and more particularly relates to an electric vehicle charging station used for waterproof vapor corrosion. Background technique [0002] An electric vehicle charging station is a station for charging electric vehicles. With the intensification of environmental pollution in recent years and the rapid development of electric vehicles, electric vehicle charging stations will surely become the focus of the automotive industry and energy industry in the future. [0003] However, the existing electric vehicle charging station generally does not have the ability to detect the humidity of its environment. During the use of the electric vehicle charging station, the surrounding environment sometimes has high humidity, which may cause the charging equipment to corrode. At present, only the method of manual periodic inspection is used to check the environmental humidity, which wastes a lot of manpower and ...
