Based on the analysis of battery management system for the range of electric vehicles

With the increasingly severe global energy crisis and environmental pollution, the development of new energy vehicles has become a global consensus. As an important representative of new energy vehicles, electric vehicles have developed rapidly in recent years with their significant advantages such as zero emission and low noise. However, the range of electric vehicles has always been the key factor restricting their further popularization, and it is of great theoretical and practical significance to explore the range of electric vehicles based on battery management system. This paper briefly describes the concept and main functions of the battery management system, analyzes the problems from the aspects of battery balancing technology, battery state evaluation, reliability and safety, and proposes corresponding optimization strategies, which has certain theoretical significance and application value.
