    摘要:

    为了避免动力锂电池由于受各种因素影响而产生自身参数不一致性带来的弊端,采用均衡技术将单体工作状态差异程度控制在可接受的范围内是保证串联电池组能够安全可靠工作的有效途径。本文构建了一种基于同芯多绕组的均衡拓扑,对该拓扑进行工作原理分析并建立分析了两种不同工作模式下的等效电路模型,搭建了实验平台进行均衡实验,结果表明该均衡拓扑在两种不同工作模式下都能实现单体间直接均衡,验证了该均衡拓扑的均衡功能。

    Abstract:

    In order to avoid the malpractice caused by different degrees of inconsistency of its own parameters caused by various factors in the power lithium battery, it is an effective way to ensure the safe and reliable operation of the battery pack in series by using the equalization technology to control the degree of difference in the single working state within the acceptable range. This paper constructed a kind of based on concentric multi-winding, analyzed working principle of the topological and set up the equivalent circuit model of two different work mode, then set up the experimental platform for equilibrium experiment, the results show that the equilibrium topology under two different working modes can work normally and validate the equilibrium topology of equilibrium function.
