What is a cell inconsistency evaluation model for series-connected battery systems?

This article presents a cell inconsistency evaluation model for series-connected battery systems based on real-world EV operation data. The open-circuit voltage (OCV), internal resistance, and charging voltage curve are extracted as consistency indicators (CIs) from a large volume of electric taxis' operation data.

How to evaluate battery inconsistency?

Inconsistency evaluation methods are summarized as statistics-based, machine learning-based and information fusion-based methods. Moreover, the improvement measures of battery inconsistency are reviewed from the aspects of the production process, sorting technology, topology optimization, equalization control and thermal management.

How to analyze battery consistency through voltage sequence?

The voltage characteristic is the direct expression of the internal performance of battery . Therefore, it is an effective method to analyze battery consistency through voltage sequence. However, the voltage sequence has high heterogeneity, including noise, missing values and abnormal values.

How to evaluate the inconsistency of parameters in a battery pack?

Inconsistent evaluation: These methods aim to evaluate the inconsistency of parameters by using machine learning algorithms to reflect the performance of battery pack. Fan et al. proposed a parameter consistency model based on the generative adversarial network (GAN) for the battery pack.

Which battery testing solution is best?

For the most commonly used battery testing system in the market is the separation solution, which is a mature solution. This application report introduces an integration battery testing solution which is simpler than the separation solution in the design.
