Abstract

The invention relates to a charging connection protection method and device. During charging, the output power of a charging device and the temperature of a charging gun and/or a charging socket are detected within a set time; the temperature change rate corresponding to the set time is obtained according to the temperature; whether the temperature change rate is greater than or equal to the temperature change threshold value corresponding to the output power or not is determined, if the temperature change rate is greater than or equal to the temperature change threshold value corresponding tothe output power, the charging is stopped. According to charging connection protection method and device, different temperature change threshold values are set according to different output powers ofthe charging device, so that the judgment of the temperature change under different output powers is more reasonable and accurate, the situation of erroneous judgement is prevented, so that the situation of abnormal connection between the charging gun and the charging socket can be effectively avoided, normal charging of a vehicle can be ensured, accidents are prevented, charging protection of the charging device and a new energy vehicle is realized, and maximizing the service lives of the charging gun and the charging socket are prolonged in a maximum degree.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle charging, and in particular relates to a charging connection protection method and device. Background technique [0002] In the current world and Chinese markets, new energy vehicles have been continuously promoted and popularized, and their ownership has increased significantly year by year. With the increase in the number of new energy vehicles, the corresponding chargers for charging new energy vehicles are also increasing sharply. [0003] However, the action of inserting and pulling out the gun before and after charging will inevitably cause a certain degree of damage to the charging gun and the charging socket, and the problem of damage to the charging gun and the charging socket has become increasingly prominent. Therefore, how to maximize the service life of the charging gun and the charging socket has become an urgent problem for the market and customers to solve. [0004] Exis...
