摘　　要：简述了新能源动力电池向着高密度、大容量、快速充电等方向发展,为了降低电池热失控的概率,更安全的运用于新能源船舶,研究高效的电池热管系统(BTMS)至关重要。简述了常见的电池散热方式:风冷、液冷、相变材料(PCM)冷却、热管冷却、复合冷却等,并对各种方式的发展和实用性进行了研究与分析。得出单种冷却方式难以满足电池散热需求,但合理的将多种方式进行耦合使用,能有效提高散热性能。总结并提出合理将PCM与热管耦合使用,可以提高对电池散热的效率和均匀性,以及延长单次使用时长,也能将储存的热能在低温环境中对电池进行恒温保护。common battery heat dissipation methods is summarized briefly is summarized briefly including air cooling,liquid cooling,phase change material(PCM)cooling,heat pipe cooling,combined cooling,etc.Through the research and analysis of the development and practicability of various methods,it is found that a single cooling method is difficult to meet the heat dissipation needs of the battery,but the reasonable coupling of multiple methods can effectively improve the heat dissipation performance.Finally,it is proposed that the coupling of PCM and heat pipe can not only improve the heat dissipation efficiency and uniformity of the battery,and extend the single-use time,but also protect the battery at a constant temperature in a low temperature environment.
