The theoretical life of the ternary lithium battery group is about 800 cycles, and it is medium in commercial charging lithium batteries. Lithium iron phosphate is about 2000 times, while lithium titanium titanium has heard 10,000 cycles. Dry -flow battery manufacturers are promised to do more than 500 times in their ternary battery specifications (under specifications). However, after the battery assembly is assembled into a battery pack, due to the common problems, the voltage and internal resistance cannot be exactly the same, and the number of cyclic life is about 400 times.
The SOC window recommended by the manufacturer is 10%~ 90%. Do not advocate deep charging and discharge, otherwise it will cause irreversible damage to the positive and negative electrode structure of the battery. If the battery is charged shallowly, the number of cycle life is at least 1,000 times. In addition, if the ternary lithium battery pack is often discharged at a high mortivity and high temperature, the battery life will be greatly reduced to less than 200 times.
Theoretically, the ternary lithium battery pack can generally have 2,000 charging and discharge cycles. However, if a large current discharge for a long time, perhaps the power of the battery may decline sharply. We can calculate it once a day and continue for more than 5 years.
However, there are still differences between the use and theory. If 1000 charging and discharge cycles are performed, the ternary lithium battery has actually been attenuated by 50%, which means that it can only run half of the original distance. So how to prevent this? Do not power without charging, do not power before charging. In addition, an excellent battery management system can also slow down the decay of ternary lithium battery packs.
According to the actual use of the vehicle, if the battery can only be charged and discharged 1,000 times, it means that the ternary lithium battery pack has now been attenuated by 50%, which means that the full power can only run half of the original journey. It is now believed that the end -stage nominal capacity of the battery life is 70%; because the battery attenuation is irreversible, the only thing we can do is change the battery.
