Abstract: Both the performance and lifetime of battery pack are substantially reduced in the cold temperatures, and it influences the performance and cost of electric vehicle strongly. Reasonable and effective heating system becomes very critical for solving the problem. This paper introduces the research development of heating system in the world, including the primary cause of the poor performance of battery pack at cold temperatures and heating of batteries, analyses the methods of heating that have been used or are researching. The limitation of current heating systems is pointed out for the future research.
