Problems solved by technology

[0002] With the popularization of electric vehicles, the charging safety of electric vehicles has become a safety issue that people cannot ignore. Since the electric charging process is an unattended process, which is different from the traditional charging system, the charging current and voltage of electric vehicles are high. During the charging process, the plug and socket are affected by the terminal structure, the number of times the product is used, and the accumulation of dust. There will often be a phenomenon of sharp rise in temperature. If it is not cleaned and maintained in time, the sharp rise in product temperature will lead to serious damage. Potential safety hazards, and greatly reduce the service life of the product, such as bursting of the plug shell, scorching of cables, natural fire caused by temperature rise, burning and hot hands, etc.

Abstract

The invention discloses a charging system comprising a charging interface and a charging wire cable of an automobile. Two ends of the charging wire cable are respectively and fixedly connected with a power source plug head and a charging plug head, wherein the power source plug head is selectively connected with an external power source interface, the charging plug head is selectively connected with the charging interface of the automobile, a temperature sensor is fixedly connected in the charging plug head, and a current control device is arranged in the charging wire cable. The charging system is simple in structure and can be used for conveniently charging an electric car; the charging system has a temperature protection function, and charging safety and reliability can be realized. A temperature protection method for charging processes can enable the electric car to have temperature safety protection property, and accidents which occur due to overheating in the charging processes when the charging plug head is not firmly plugged or is damaged can be prevented.

Description

technical field [0001] The invention relates to the technical field of charging systems and methods for electric equipment, in particular to a charging system and a temperature protection method during charging.
