Performance of different Electric vehicle Battery packs at low temperature and Analysis of Intelligent SOC experiment

摘要

This manuscript summarizes the SOC (State of charge) estimation methods of electric vehicle battery packs at low temperature, analyzes the performance of common battery packs of electric vehicle and the influence of low temperature, introduces the traditional SOC estimation method and the emerging cryogenic intelligent lifting algorithms, and summarizes their advantages and disadvantages. Combined with intelligent algorithm and battery model, the development of SOC estimation of battery packs at low temperature is prospected.
