摘要

为了减少电池组的不一致性，提高电池组的整体性能，延长电动汽车行驶里程，本文提出了一种创新的锂电池组平衡转换器。在电动汽车行驶过程中，这种拓扑结构可以方便地将多余的能量从一个电池转移到任何其他电池，即由改进的双向DC-DC转换器组成的主动电池组管理，并采用自然和强制混合主动平衡控制(HNFABC)。根据HNFABC，在Matlab/Simulink中建立了含4节电池的平衡电路仿真模型。仿真结果表明，HNFABC不仅优于其他传统的平衡控制策略，而且减少了平衡过程中的能量损失。

Research on Hybrid Natural and Forced Active Balancing Control of Battery Packs State of Charge Based on Unscented Kalman Filter

To reduce the inconsistency of battery packs, to enhance the overall performance of battery packs, and to prolong electric vehicle mileage an innovative balancing converter for the lithium battery pack is proposed in this paper. During the driving process of an electric vehicle, this topology makes it convenient to transfer extra energy from one cell to any other cells, namely, active pack management composed of improved bidirectional DC-DC converters which are presented with the Hybrid Natural and Forced Active Balancing Control (HNFABC). According to HNFABC, the simulation model of the balancing circuit is built with four batteries in Matlab/Simulink. The simulation results show that HNFABC is not only better than the other traditional balancing control strategies but also reduces the energy loss in the balancing process.
