Research on performance of thermal management system for lithium-ion power battery

Abstract

According to battery thermal management system’s design theory, a battery module with thermal management system is designed in this article, and the thermal management system model is simulated. By establishing thermal management system’s simulation model, modular thermal management system’s performance is analyzed.The simulation consequences show that the liquid cooling plate’s outlet temperature is higher than the inlet temperature, so the temperature rise and outlet temperature of the cooling liquid of a single battery module that cools system should be properly controlled. Through the thermal imager experiment, the test consequences are consonant with the simulation analysis’s conclusions.The reliability and accuracy of the simulation analysis is verified by the experiment, and shows the rationality of the design of the thermal management system for power battery.
