The balancing technology is important for battery management systems. However, the widely used passive balancing technology has disadvantages such as a low efficiency and a long balancing time, while the active balancing technology which is more efficient has problems such as complex control and high cost. In response to the status quo, a double-layer balancing topology circuit based on an improved Buck converter is proposed. Its circuit parameters and balancing strategy are designed by taking into account the issue of matching, its working principle is analyzed in detail, and its economic cost is compared and analyzed, so as to verify the feasibility and economy of the proposed scheme. The simulation analysis of a model based on MATLAB/Simulink shows that the balancing time of the proposed scheme is reduced by 40.4% compared with that of the traditional adjacent cell balancing system. The results of a battery pack balancing test show that this scheme has advantages of a simple structure and simple control. It can quickly realize the balancing of 26650 lithium iron phosphate battery, and it only took 20.4 min to reduce the maximum differential voltage of four battery packs in series from 141 mV to within 50 mV.

均衡技术对于电池管理系统至关重要，广泛采用的被动均衡存在效率低、均衡时间长等缺点，而更高效的主动均衡存在控制复杂和成本高等问题。针对该情况，提出1种基于改进型Buck变换器的双层均衡拓扑电路，匹配性设计了其电路参数和均衡策略，详细分析了其工作原理，并对比分析了其经济成本，验证了该方案的可行性和经济性。MATLAB/Simulink模型仿真分析表明，该方案的均衡时间相比于传统相邻单体均衡系统减少了40.4%。搭建的电池组均衡实验结果表明，该方案具有结构简单、控制简便的优点，可快速实现26650磷酸铁锂电池的均衡，将4串电池组最大压差从141 mV控制到50 mV以内仅需20.4 min。

均衡技术对于电池管理系统至关重要，广泛采用的被动均衡存在效率低、均衡时间长等缺点，而更高效的主动均衡存在控制复杂和成本高等问题。针对该情况，提出1种基于改进型Buck变换器的双层均衡拓扑电路，匹配性设计了其电路参数和均衡策略，详细分析了其工作原理，并对比分析了其经济成本，验证了该方案的可行性和经济性。MATLAB/Simulink模型仿真分析表明，该方案的均衡时间相比于传统相邻单体均衡系统减少了40.4%。搭建的电池组均衡实验结果表明，该方案具有结构简单、控制简便的优点，可快速实现26650磷酸铁锂电池的均衡，将4串电池组最大压差从141 mV控制到50 mV以内仅需20.4 min。

The balancing technology is important for battery management systems. However, the widely used passive balancing technology has disadvantages such as a low efficiency and a long balancing time, while the active balancing technology which is more efficient has problems such as complex control and high cost. In response to the status quo, a double-layer balancing topology circuit based on an improved Buck converter is proposed. Its circuit parameters and balancing strategy are designed by taking into account the issue of matching, its working principle is analyzed in detail, and its economic cost is compared and analyzed, so as to verify the feasibility and economy of the proposed scheme. The simulation analysis of a model based on MATLAB/Simulink shows that the balancing time of the proposed scheme is reduced by 40.4% compared with that of the traditional adjacent cell balancing system. The results of a battery pack balancing test show that this scheme has advantages of a simple structure and simple control. It can quickly realize the balancing of 26650 lithium iron phosphate battery, and it only took 20.4 min to reduce the maximum differential voltage of four battery packs in series from 141 mV to within 50 mV.
