Battery life is 5 to 8 years.
Under ideal conditions, ternary lithium batteries can complete about 500 to 2,000 charge and discharge cycles, and the battery capacity can always stay at about 80% of its capacity. initial capacity. According to 1C charge and discharge rate and 2000 cycles, the corresponding service life can be about 5-8 years. Actual battery life is also affected by factors such as temperature, charging habits (e.g. whether it is often fully charged and discharged), charge size, etc., so differences individual are important.
The lifespan of ternary lithium batteries is generally around 10 to 15 years.
The number of charge and discharge cycles of the ternary lithium battery is about 2,000 times, and the theoretical value is 3,500 times, i.e. what'Battery attenuation is less than 20% after 3500 times. charging and discharging. In actual use, the battery life will be greatly affected by the manufacturer's manufacturing technology, battery management technology, external environment, car owner's driving habits, charging methods, etc.
Under normal circumstances, it can be used for 10 years. Generally, the three-electric warranty of car manufacturers is 8 years and 120,000 kilometers. Some car manufacturers also offer a three-electric lifetime warranty. If it is not ordinary household use, but operational use, it will be difficult to use it for eight years. With the development of battery technology, including innovations in new battery materials, battery management technology and battery structure, performancePower batteries have become more durable and safer.
Factors affecting the service life of ternary lithium batteries
During use, due to improper use, irreversible electrochemical reactions occur. will produce inside the lithium battery, leading to. a decrease in capacity, such as the decomposition of the electrolyte inside the battery and the loss of activity of the active materials inside the battery, will directly lead to a sharp reduction in battery life ternary lithium.
Of course, the end of the battery life of the electric vehicle does not mean that the battery cannot be charged or discharged, but that the discharge capacity of the battery at this time has significantly decreased compared to the new state of the battery if it continues to be used, which will bring a bad car experience to thex users. Since power battery life standards were established a few years ago, the battery capacity was low and the range of electric vehicles was short. The autonomy was reduced to less than 80% of new batteries. I feel like the battery life has been significantly reduced.
For example, the range is originally 200 kilometers, but the battery has dropped to 80% and it needs to be recharged after driving 160 kilometers. Nowadays, the range of electric vehicles is already high and 20% attenuation is no longer so good for users' car experience.
