The relevant information on the lifespan of ternary lithium batteries for new energy vehicles is as follows:
1. Theoretical cycle life: Theoretically, ternary lithium batteries have a cycle life of about 800 times, but under high-quality battery systems, the cycle life can reach 1000-2000 times.
2. Actual service life:
In the field of new energy vehicles, high-quality ternary lithium batteries can be used normally for 8 years, with a driving range of 150000 to 200000 kilometers, and generally have a lifespan of 5 to 8 years.
If used properly, ternary lithium batteries can be used in electric vehicles for at least 5 years, but if used improperly, the battery life may significantly deteriorate within 2 to 3 years.
The lifespan of ternary lithium-ion batteries ranges from 5 to 20 years, with an average lifespan of around 8 years.
3. Factors affecting lifespan:
Use environment and maintenance level, such as avoiding overcharging and discharging, avoiding high and low temperature environments, regularly maintaining and checking the charging status, and cleaning the surface.
Drivers' usage habits, such as avoiding deep discharge and frequent fast charging as much as possible.
The material quality of batteries, such as ternary lithium batteries, typically uses graphite for the negative electrode and nickel, cobalt, manganese or nickel, cobalt, aluminum for the positive electrode.
When the battery capacity decays to 70%~80% of its original capacity, it is usually considered to have reached the end of its service life and the battery needs to be replaced.
