Pack battery inconsistency

4 FAQs about [Pack battery inconsistency]

What is a battery pack inconsistency model?

An inconsistency model is composed of Gaussian mixture model and mixture Copula model. The distribution of single parameter and correlation between parameters are described. Battery pack inconsistency quantification experimental platform is developed. Energy estimation errors are less than ±1% between simulation and platform experiment.

Does large-scale grouping lead to inconsistency in a 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.

Does battery pack inconsistency affect output energy?

Therefore, the influence degree of the battery pack inconsistency on the output energy needs to be studied based on a battery pack inconsistency model, a newly built experimental platform with adjustable battery pack inconsistency parameters, and the method of multiple linear regression analysis. 1.2. Contributions of this work

Why is inconsistency a key factor affecting the performance of battery packs?

The inconsistency, which is cell to cell variations within battery packs, is a key factor influencing the performance of battery packs , , . The inconsistency not only affects the output power and energy of the battery pack, but also relates to the state of health and safety of the battery pack , .
