According to the single lithium-ion battery heat generation model, the heat generation rate was estimated. By the CFD software, two-dimensional finite element model of 35Ah lithium manganese oxide battery pack under cooling was established, and then the temperature and flow distribution results were solved. The temperature in the battery pack was measured by experiment. The result between simulation and experimental was compared, and it was presented that two-dimensional simulation was nearly consistent and can be used to study the temperature distribution in the battery pack. And some improved measures on cooling were put forward by analyzing the temperature distribution of the existing pack.
