How to sort retired batteries?
At present, there is no recognized effective sorting method for retired batteries, and most of them still take capacity and internal resistance as sorting criteria, which is utilized for fresh batteries sorting after they are produced.
How to sort a second-use battery?
Step 1: Perform a feature extraction experiment on the second-use batteries that need to be sorted, so as to extract the sorting characteristic parameters of each battery. capacity test, HPPC test and low current discharging experiment are conducted to determine battery capacity, internal resistance and C loss, which is caused by LAM.
Why do I need to sort second-use batteries?
Sorting of second-use batteries is a necessary before grouping. Many factors, such as operating conditions, ambient temperature and cell inconsistency will affect the cell aging. Therefore, sorting factors for second-use batteries are needed to ensure the pack performance and satisfy the requirement for second-use operation.
