摘要：Electric vehicles represent an inevitable trend in the development of green transportation in the new era, among which battery thermal management plays a crucial role. To investigate the factors influencing battery cooling performance, 3D-models of four different cooling structures were established. The correctness of the heat data generated by the battery at 2C and 3C discharge rates was verified through experiments. The influences of the thermal resistance of battery conduction, contact and convective heat transfer on the cooling effect were studied. The results showed that the thermal resistance of the battery was the most critical factor affecting the battery temperature. When the thermal resistance of the battery itself was reduced by 50 %, the maximum temperature of the battery dropped by 5.25 K, the temperature rose of the battery decreases by 44.1 %, and the temperature difference decreased by 45.6 %. Additionally, the addition of high thermal conductivity thermal grease proved effective in reducing battery temperature, though its thickness had only a minor impact. As the coolant flow velocity increases, the maximum temperature of the battery decreased accordingly. However, when the proportion of convective heat transfer thermal resistance dropped below 5 %, further increasing the coolant flow velocity did not significantly enhance the heat exchange efficiency. This paper provides a comprehensive analysis of the heat transfer process in battery thermal management systems, identifies the dominant sources of thermal resistance during the heat transfer process, and offers design insights for the development of subsequent thermal management systems.
