First, the capacity of each cell in the battery pack Qi, the difference in remaining chargeable capacity of each cell when the battery pack reaches the charge cutoff condition Qdi, and the internal resistance of each cell Ri are determined to accurately characterize the battery pack consistency.
The results show that the proposed method can accurately diagnose the capacity consistency of the tested battery pack, which provides a basis for battery pack performance testing and maintenance. The capacity inconsistency among commercial lithium-ion battery packs is an important factor affecting their service life.
In this paper, the lithium iron phosphate battery capacity increase curve (IC curve) was used as an analysis tool. It is found that the IC curve characteristic peaks of different monomers in the battery pack can reflect the consistency between the monomers.
The actual capacity was compared and found to be consistent with the battery consistency trend of capacity characterization. This method can quickly describe the battery pack consistency problem, and can be applied during the normal charging process of the battery pack.
