摘要：

为了提高电动汽车动力电池系统的热安全性及可靠性,使得动力电池系统维持在正常的工作温度范围之内,该文基于柔性复合相变材料的控温特性,采用熔融共混与有机溶剂挥发相结合的方法,制备由苯乙烯-丁二烯-苯乙烯嵌段共聚物/石蜡/膨胀石墨(SBS / PA/ EG)组成的柔性复合相变材料,并将其与板式热管耦合以显著提高动力电池热管理系统的均温和控温特性。结果表明：柔性复合相变材料（SBS/PA/EG）的导热系数在室温下可提升至0.62 W/(m·K),潜热焓值可达102 J/g。以柔性相变材料耦合板式热管作为电动汽车的电池热管理系统用在电池模组中,当电芯在3 C倍率下放电时,其最高温度控制在42 ℃ 之内,电池间温差缩小至1.0 ℃,显示出优异的控温及均温效果。

Abstract:

A novel flexible composite phase change material (PCM) composed of styrene-butadiene-styrene block copolymer / paraffin wax /expanded graphite (SBS / PA/ EG) was prepared through melt blending and organic solvent volatilization to improve the thermal safety and reliability of electric vehicle power battery system and to maintain the power battery system within the normal operating temperature range, considering the temperature control characteristics of flexible composite phase change material. The composite PCM was coupled with a plate heat pipe for significantly improving the homogenization temperature and temperature control characteristics of battery thermal management system. The results show that the thermal conductivity of flexible composite phase change material with SBS/PA/EG is increased to 0.62 W/(m?K) at room temperature, and the latent heat enthalpy reaches 102 J/g. When flexible PCM coupled plate heat pipe as the battery thermal management system of electric vehicles was utilized in the battery module, the maximum temperature can be controlled below 42 ℃ and the temperature difference among batteries maintains within 1.0 ℃at 3 C discharged rate of batteries, exhibiting excellent temperature control and temperature uniformity effect.
