摘　　要：低温下,动力电池的充放电性能、使用寿命都将大幅度下降,直接影响电动汽车的成本和使用方便性,加热系统成为解决这一问题的关键。介绍了国内外关于电池组加热系统的研究进展,包括影响动力电池低温性能的主要因素和动力电池组加热方法两个方面,重点分析了各种已被采用和在研究中的加热方法,并以此为基础,提出了加热系统有待提高之处,为后续研究提供参考。Both the performance and lifetime of battery pack were substardJally reduced in the cold temperatures, and the performance and cost of electric vehicle were strongly influenced. Reasonable and effective heating system were very cdtical for solving the problem. The research development of heating system in the world was introduced, including the primary cause of the poor performance of battery pack in cold temperatures and heating of batteries. The methods of heating were analyzed. The limitation of current heating systems was pointed out for the future research.
