Abstract

The invention relates to a temperature monitoring system and a temperature monitoring method for an electric vehicle charging assembly. The temperature monitoring method comprises temperature data acquisition steps and control steps. The temperature monitoring method comprises the temperature data acquisition steps of acquiring a temperature threshold of an electric vehicle charging socket and a temperature threshold of a charging gun assembly, and acquiring a temperature value of the electric vehicle charging socket and a temperature value of the charging gun assembly. The temperature monitoring method comprises the control steps of performing charging control of an electric vehicle based on the temperature value of the electric vehicle charging socket, the temperature threshold of the electric vehicle charging socket, the temperature value of the charging gun assembly and the temperature threshold of the charging gun assembly. The temperature monitoring system and the monitoring method of the electric vehicle charging assembly provided by the embodiment of the invention ensure that the temperature in the charging process of the vehicle does not exceed the tolerable temperature ofthe charging gun assembly and the electric vehicle charging socket through the whole vehicle control, thereby ensuring the safety of the charging process.

Description

technical field [0001] The invention belongs to the technical field of new energy vehicles, and in particular relates to a temperature monitoring system and a monitoring method of a charging component of an electric vehicle. Background technique [0002] Both electric vehicles (BEV) and hybrid vehicles can be powered by the on-board power supply and drive the wheels with electric motors. Because electric vehicles (BEV) and hybrid vehicles use electric power to drive vehicles, there is no exhaust emission during driving, and their impact on the environment is smaller than that of traditional fuel vehicles, so their application prospects are broad. [0003] Electric vehicles and hybrid vehicles are powered by batteries and need to be powered by batteries. Especially for electric vehicles, it is necessary to insert the cable charging plug into the charging socket of the electric vehicle at the charging station, and use alternating current to charge the storage battery of the e...
