基于结构逻辑树的电池组SOC估算

Determination of battery pack SOC based on structural logic tree

为了实时估算电池组SOC,分析了当前SOC定义的局限性,并考虑电池组的结构和单体电池的差异性,明确电池组SOC定义。提出基于结构逻辑树的电池组SOC估算模型,利用结构逻辑树描述电池组单体电池之间的逻辑关系,并基于结构逻辑树的运算规则,实现电池组SOC的快速估算。实验证明,该模型能够快速有效地估算电池组SOC。

The concept of the battery pack SOC was redefined to estimate the battery pack SOC in real time. Battery pack structure and the individual variation of each cell into consideration were considered, and battery pack SOC definition was cleared. A battery pack estimation model based on Structural Logic Tree was proposed, in which the logical relationship of each cell could be described. Based on the arithmetic rule of structural logic tree, the quick estimation of battery pack SOC could be realized. Experiment shows that the method is quick and effective.
