锂离子电池主动均衡拓扑研究综述OA

Battery active equalization technology is an effective means to improve the performance and prolong the service life of battery packs.Through literature research and comparison,the working principles,advantages,limitations,and application scenarios of various active equalization topologies are systematically analyzed,with a focus on the design characteristics and performance of mainstream topologies based on capacitors,inductors,transformers,and switch arrays.The results indicate that switch-capacitor-based topologies feature simple structures and low costs.Inductor-based topologies exhibit significant advantages in equalization efficiency and speed,while transformer-based topologies,owing to their isolation characteristics,are suitable for modular design in high-voltage and high-capacity battery systems.Additionally,as key modules for circuit gating and reconfiguration,switch arrays are widely integrated into various equalization topologies.Furthermore,the integration potential and prominent advantages of hybrid equalization topologies are analyzed.It is anticipated that summarizing the applicable conditions and optimization directions of various topologies will provide theoretical references for the intelligent and high-efficiency development of battery active equalization technology.
