Review of External Preheating Techniques for Power Battery in Electric Vehicles at Low Temperatures

Author(s): Zibo Ye, Xingfeng Fu*, Kai Wen, Feng Pei, and Hai Jiang

Electric drive vehicles offer a hopeful solution for significant decreases in greenhouse gas emissions and reliance on fossil fuels. Exploring efficient battery preheating techniques is essential due to the fact that harshly cold climates substantially decrease the discharge efficiency of electric vehicles, frequently necessitating lengthy warming periods for the battery upon startup. To this end, this paper reviews currently popular preheating strategies used in passenger electric vehicles. Initially, the postmortem analysis of the cycled anodes charged at low temperatures is reviewed briefly. Following this, detailed descriptions of different external preheating system designs for battery warm-up are presented. Furthermore, the improved charging str... view more»
