The consistency of lithium-ion battery packs should be judged by using special tools to measure capacity, internal resistance, and charge and discharge curves. To measure the capacity internal resistance and discharge platform of a single battery, it also depends on the process level of lithium battery assembly and the battery performance requirements of specific products. The consistency of a lithium battery pack refers to the sameness of important characteristic parameters of a group of lithium batteries. The consistency of a battery refers to the consistency of battery weight and voltage. There are multiple strings of cells in the same battery pack. Each parameter is best. All are in a smaller range, which is good for consistency. The higher the consistency of the capacity, internal resistance, and charge-discharge curve of batteries produced with the same material and the same process, the better. Whether batteries can be assembled into battery packs on a large sca

If the remaining capacity/initial capacity=80% is used as the end point of the test, the current 1C cycle life of the lithium iron phosphate battery laboratory is more than 3500 times, and some reach 5000 times, while the 1C cycle life of the ternary lithium ion battery laboratory is 2500 times about. In terms of the true cycle life, the lithium iron phosphate battery pack has a much longer true cycle life than the ternary lithium ion battery. Under the same number of cycles, the remaining capacity of the lithium iron phosphate battery is much more than that of the ternary lithium ion battery. According to laboratory data, the remaining capacity of the ternary lithium ion battery after 3900 cycles is 66%, and the remaining capacity of the lithium iron phosphate battery after 5000 cycles is 84%. The battery cycle life of the lithium iron phosphate material is higher than that of the ternary material lithium ion battery. Lithium iron phosphate batteries have obvious adv
