Investigation of the cooling performance of lithium titanate square soft pack lithium battery

为了研究不同相变材料对大容量锂电池的冷却效用,同时研究不同电池表面相变材料裹覆面积和不同级别放电倍率条件下电池模块的冷却速度,以相变温度各不相同的三种固态相变材料为研究对象,对锂电池进行包裹并对电池放电后的冷却过程进行定位。最后,采取相变材料与微通道铝扁管协同作用的方法来加快电池的冷却进程,实验结果表明通过该方法能够获取更好的冷却效果,具有较高的推广应用价值。

In order to study the cooling effect of different phase change materials on large capacity lithium battery and the cooling rate of battery module under the conditions of different surface area of phase change materials and different discharge rate,three kinds of solid phase change materials with different phase change temperatures were used as the research objects to wrap the lithium battery and locate the cooling process after discharge.Finally,phase change material and microchannel aluminum flat tube are used to accelerate the cooling process of the battery.The experimental results show that this method can obtain better cooling effect,and has high application value.
