Temperature Rise Simulation Method for ChaoJi Charging Connector of Electric Vehicles
During the operation of high-power charging piles,prolonged high current charging causes significant temperature rise in the connectors.This paper focuses on the development needs of high-power charging for electric vehicles and conducts research on the temperature rise simulation modeling and software simulation of ChaoJi charging connectors.Firstly,it simplifies the structure of the connector to be cylindrical,and studies the thermal effect model of the connector contact point based on the type of contact structure and the influencing factors of contact resistance.Secondly,it studies the temperature rise simulation method of ChaoJi charging connector.Finally,the paper carries out software thermal simulation on the ChaoJi connector and verifies the temperature rise model of the ChaoJi charging interface.It draws a conclusion that the temperature rise is related to the square of the energized current.The ChaoJi charging connector temperature rise model and software thermal simulation studied in this paper fill the gap in the research of charging interface temperature rise,and have important research significance to a certain extent.
