In this paper, a method for evaluating and predicting the inconsistency of lithium-ion battery pack in electric vehicles based on actual operating data is proposed.
Contact UsBattery packs are applied in various areas (e.g., electric vehicles, energy storage, space, mining, etc.), which requires the state of health (SOH) to be accurately estimated. Inconsistency, also known as cell variation, is considered a significant evaluation index that greatly affects the degradation of battery pack.
Abstract: The large-scale grouping of the battery systemleads to the inconsistency of the battery pack. Aiming at tacking this issue, an inconsistency evaluation method is deployed for the battery pack based on an improved Gaussian mixture model (GMM) and feature fusion approach.
An online capacity estimation approach with the extended Kalman particle filter (EPF) is put forward for capacity estimation. Further, an improved GMM is proposed to visualize battery pack inconsistency, using theK-means++ algorithm to initialize category centers. The standard deviation coefficient approach quantifies the inconsistency.
Thirdly, the parameters of the battery pack inconsistency model are divided into GMM and MCM model parameters according to the established inconsistency model, and multiple linear regression analysis is used to study the influence degree of these two parts model parameters on output energy respectively.
