Consistency evaluation features can be extracted online. An improved fuzzy clustering algorithm is developed to evaluate pack consistency. The proposed methods are validated by nine months of electric vehicle data. Consistency is an essential factor affecting the operation of lithium-ion battery packs.
Qian et al. evaluated the consistency of grouped lithium-ion batteries based on characteristic peaks of incremental capacity curves. This method can quickly describe the consistency issue of battery packs and can be applied during the charging process of battery packs.
Considerable research efforts have been devoted to the diagnosis and evaluation of battery pack consistency. To diagnose faults and provide early warning of the inconsistencies, existing methods can be mainly divided into model-based and data-driven methods .
In Ref. , the voltage variation rate is employed to evaluate the pack consistency. Model-based: These approaches employ filters or parameter identification algorithms to estimate the battery parameters. Then, the pack consistency is evaluated by the parameter distribution.
The results show that with the usage of batteries, the difference between the cells becomes more serious, which weakens the pack consistency. Besides, the relationship between the consistency attenuation rate and the driving mileage can be approximated by a first-order function. The higher mileages will aggravate the pack inconsistency.
Overall, the pack consistency is relatively good. After March 2013, batteries are gradually divided into three categories. The second cluster is mainly represented by the former batteries. The third cluster refers to 8#, 32#, 57#, 58#, 59#, 60#, 74#, 98#, 104#, 116#, etc. This category is mostly separated from the previous cluster 1.
