Abstract

BMS (Battery Management System) plays a vital role in the safe operation of new energy electric vehicles and the improvement of battery performance. This paper briefly analyzes the development status of BMS at home and abroad, the current market share of new energy electric vehicle power battery system, and the cost structure of new energy vehicles. The comparative analysis of energy dissipation and energy non-dissipative two types of battery equalization control technology performance indicators; The current SOC (State of Charge) evaluation algorithm is reviewed, and the principle, advantages and disadvantages of various methods are analyzed. The research status of lithium-ion battery pack optimized charging control technology at home and abroad is introduced. The relationship between the three key technologies of BMS is summarized. And look forward to the future development trend of BMS.
