In order to extend the operating temperature range of lithium-ion power batteries and ensure their stable performance,an advanced thermal management system design is adopted.This paper focuses on the use of computational fluid dynamics(CFD)simulation techniques to explore the thermal generation characteristics of battery cells under changing operating conditions,the temperature distribution at the module level,and the performance during heating and cooling processes.By comparing the simulation data of various heat dissipation architectures horizontally,the heat exchange mechanism of the battery system can be refined.The cooling test results of the actual vehicle confirm that the optimized thermal management scheme can effectively maintain the battery in the appropriate operating temperature range,thus ensuring the efficiency and durability of the battery.
