本工作报告的实验室测试结果的锂离子电池设计的电动滑板车的应用。在本实验研究中，研究了四种不同的散热模式：（1）自然对流冷却;（2）泡沫铝传热基质的存在;（3）相变材料（PCM）的使用;以及（4）泡沫铝和PCM的组合。使用PCM的目的是降低锂离子电池的温升，并在电池模块中形成均匀的温度分布。这显然是合理的，看看在这项工作中提出的实验结果。在电池之间的空隙中使用高导热性铝泡沫降低了锂离子电池的温度上升，但当在高环境温度（例如通常在夏季发生的那些）下操作时是不够的。与没有热管理的第一种情况相比，使用具有PCM的铝泡沫导致约50%的显著温度下降。它还在电池模块内提供均匀的温度分布，这对于所用电池的有效性能非常重要。实验室的结果进行了建模，使用2-D热模型占四种不同的散热模式和良好的协议之间的模拟和实验结果。
This work reports the laboratory test results of a Li-ion battery designed for electric scooter applications. Four different modes of heat dissipation were investigated in this experimental study: (1) natural convection cooling; (2) presence of aluminum foam heat transfer matrix; (3) use of phase change material (PCM); and (4) combination of aluminum foam and PCM. The objective of using the PCM is to lower the temperature rise of the Li-ion cells and create a uniform temperature distribution in the battery module. This is clearly justified looking at the experimental results presented in this work. The use of high thermal conductivity aluminum foam in the voids between the cells reduces the temperature rise of the Li-ion cells but is insufficient when operated in high ambient temperature such as those usually occur in summer. The use of aluminum foam with PCM causes a significant temperature drop of about 50% compared to the first case of no thermal management. It also provides uniform temperature distribution within the battery module, which is important for the efficient performance of the cells used. The laboratory results were modeled using a 2-D thermal model accounting for the four different modes of heat dissipation and good agreement was obtained between the simulation and experimental results.
