集中式变压器电池组均衡电路的仿真研究
Simulation research of battery pack equalization circuit for centralized transformer
摘要
Abstract
To resolve the problem of battery performance degradation and life shortening caused by the inconsistency of the performance of single cell in battery pack,a battery pack equalization circuit for centralized transformer is proposed based on equilibrium method. The Buck-Boost circuit equilibrium method and centralized transformer equilibrium method are combined to realize the two-way balanced target of energy transfer between single cells via the stratified equilibrium strategy. The voltage at both ends of the switch tube in the centralized transformer balanced circuit is decreased by means of RCD protection circuit to reduce the switch tube loss and protect the switch tube. The mathematical model of the battery equalization circuit was further es-tablished and the simulation analysis was carried out. The research results show that the battery pack equalization circuit for cen-tralized transformer is superior to the traditional Buck-Boost equalization circuit in terms of energy efficiency.关键词
