Research and Implementation of Temperature-rise Test System for Electric Vehicle Charging Coupler

The safety performance of Electric Vehicle (EV) charging equipments during the charging process will be the critical factor to the development of EV's Industry. Because of the high investment costs and the low accuracy of temperature-rise test system for EV charging coupler, a new remote test system including virtual instrument LabVIEW technology and communication transformation technology is applied to practical work. One temperature-rise test system designed for EV charging coupler is shown in this paper. With the advantages of LabVIEW as graphic programming and multithreading, real-time data acquisition, on-line monitoring and dynamic data preservation can be achieved by this temperature-rise test system. This test system simulates the change status of current data and makes a comprehensive research and evaluation temperature-rise characteristics of the charging coupler by analyzing the collected parameters and historical data when charging for EV.
