基于蛇形通道的电池组液冷方案设计与优化

Compared with traditional vehicles, electric vehicles have a broad application prospect under the background of rapid development of new energy. As one of the power sources of electric vehicles, the performance of battery is easily affected by temperature. Battery thermal management system, which can control its working temperature, is of great significance to extend battery service time and ensure the safety and stability of electric vehicles. Aimed at the phenomenon that the temperature of power battery itself is too high, the heat generation characteristics of the battery are analyzed firstly, and then a set of liquid cooling thermal management scheme based on serpentine channel is proposed and optimized. Finally, the simulation results in temperature field show that the optimized liquid cooling structure has an obvious impact on the working environment of the battery pack. Especially under the high temperature condition, the battery can work in the optimal temperature range of 20℃-35℃, and meet the requirement that the temperature difference within the battery pack is less than 10℃.
