Both the performance and lifetime of battery pack were substantial y reduced in the cold temperatures, and the performance and cost of electric vehicle were strongly influenced. Reasonable and effective heating system were very critical 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.
