Research on Battery Equalization Control Based on Improved Bidirectional Cuk Converter
In order to improve the equalization efficiency of lithium-ion power battery packs,a battery equali-zation control method based on an improved bidirectional Cuk converter was proposed.The improved bidirection-al Cuk converter is effectively combined with flyback transformer,and the equalization circuit is designed for the improved bidirectional Cuk converter and flyback transformer.The simulation results show that under static and dynamic conditions,the battery voltage and SOC can reach the equilibrium goal quickly,and the single cell has no redundant repetitive charge and discharge,which reduces the energy consumption of the system due to repeti-tive charge and discharge.The experimental results of the target system show that the simulation results are consistent with the experimental results,which verifies the rationality of the method and provides a method ref-erence for improving the battery balancing efficiency.
