摘要
动力电池系统的散热效果对其寿命与工作性能有较大影响,以电芯、模组及电池包系统为研究对象,进行有限元建模分析,分别对V1电池包系统、V2电池包系统的温度进行比较分析,通过对比两种不同结构设计电池包的系统内部温度分布、电芯温度分布、模块电芯温差、最高温度区域,发现在相同的电压与电容量的要求下,合理的电池包结构设计可以有效降低电池包的温度。计算仿真结果对动力锂电池系统的结构设计和实际生产具有一定的指导意义。
The thermal performance of the power battery system has great influence on its life and work performance. The batteries, modules and battery pack systems were modeled by the finite element analysis technique, and temperature of V1 and V2 battery pack systems with different structures were compared. By comparing the internal temperature distribution of the systems, the internal temperature distribution of the cells, the cell temperature difference and the maximum temperature range, it is found that under the same voltage and capacitance requirements, the reasonable design can effectively reduce the temperature of the battery pack. The simulation results have some guiding significance for the structure design and actual production of power lithium battery system.
