Bidirectional pluggable charging system and temperature protection method for charging process

Abstract

The invention discloses a bidirectional pluggable charging system. The charging system comprises an automobile charging interface, a charging cable and a charging pile, wherein the two ends of the charging cable are fixedly connected with a charging plug and a power plug respectively; the charging plug is selectively connected with the automobile charging interface; the power plug is selectively connected with a power interface in the charging pile; each of the automobile charging interface and the power interface comprises a temperature sensor; the temperature sensors are fixed on the inner sides of the automobile charging interface and the power interface; and a current control apparatus is also fixed in the charging pile. The bidirectional pluggable charging system is convenient to charge the electric vehicle and has a temperature protection function as well. A temperature protection method for a charging process has temperature protection performance, so that accidents caused by insecure plugging or damage of the charging plug 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 two-way plug-in charging system and a temperature protection method during charging. Background technique [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 prod...

[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.
