Research on Equilibrium Strategy of Hybrid Electric Vehicle Battery Management System
Battery pack equalization technology is one of the most critical technologies in battery management system (BMS).Equalization technique can greatly reduce the difference between each single battery in the battery,effectively prevent overcharge and overdischarge,maintain battery balance,thereby prolonging the service life of the battery,and also greatly improve the use efficiency of the battery.This paper first selects the standard for battery equalization,enumerates the advantages and disadvantages of lossless balance and loss balance,and emphatically analyzes the inductance and capacitance,transformer and other lossless equalization scheme based on lossless transformer.Based on equilibrium selection,equalization circuit and balanced control strategy is designed,which is proved feasible,greatly improved the inconsistency between single cells of the battery group.
