设计了一种采用新型相变材料（PCM）热管理系统的电动滑板车用锂离子电池。使用PCM的被动热管理系统可以控制锂离子电池的温度偏移并保持温度均匀性，而无需使用空气/液体冷却系统中的风扇、鼓风机或泵等主动冷却组件。因此，可以利用这种新型形式的热管理系统来实现紧凑、轻质和节能系统的优点。显示了锂离子电池子模块的模拟结果，该子模块由9个18650锂离子电池组成，周围是熔点在41 ° C和44°C之间的PCM。研究了在PCM内使用铝泡沫和附接到电池模块的翅片，以克服PCM的低热导率和低自然对流传热系数。在泡沫铝和铝翅片的存在下的PCM性能的比较结果被示出。电池模块还针对夏季和冬季条件进行了模拟。研究了空气冷却对锂离子电池性能的影响。这些模拟结果表明，成功使用的PCM作为一个潜在的候选人热管理解决方案，在电动踏板车的应用，因此为其他电动汽车的应用。
A lithium-ion battery employing a novel phase change material (PCM) thermal management system was designed for an electric scooter. Passive thermal management systems using PCM can control the temperature excursions and maintain temperature uniformity in Li-ion batteries without the use of active cooling components such as a fan, a blower or a pump found in air/liquid-cooling systems. Hence, the advantages of a compact, lightweight, and energy efficient system can be achieved with this novel form of thermal management system. Simulation results are shown for a Li-ion battery sub-module consisting of nine 18650 Li-ion cells surrounded by PCM with a melting point between 41 and 44°C. The use of aluminum foam within the PCM and fins attached to the battery module were studied to overcome the low thermal conductivity of the PCM and the low natural convection heat transfer coefficient. The comparative results of the PCM performance in the presence of Al-foam and Al-fins are shown. The battery module is also simulated for summer and winter conditions. The effect of air-cooling on the Li-ion battery was also studied. These simulation results demonstrate the successful use of the PCM as a potential candidate for thermal management solution in electric scooter applications and therefore for other electric vehicle applications.
