The consistency of lithium-ion battery packs should be judged by using special tools to measure capacity, internal resistance, and charge and discharge curves.
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.
