How long is the life of BYD ternary lithium battery?

If a ternary lithium battery is used in a high temperature environment, such as a temperature above 350C, the battery storage capacity will continue to decrease, resulting in a battery life that is not as long as it is in a normal temperature environment. The ternary lithium battery needs to reach its ideal service life when the electrons remain flowing for a long time.

The theoretical life of the BYD ternary lithium battery is about 800 cycles, which is medium in commercial rechargeable lithium batteries. Lithium iron phosphate is about 2000 times, and lithium titanate is said to reach 10,000 cycles. At present, the mainstream battery manufacturers promise more than 500 times in the ternary battery specifications produced by them. However, after the batteries are assembled into battery packs, the voltage and internal resistance may not be exactly the same due to the consistency problem. The cycle life is approximately 400 times.

BYD ternary lithium battery life can be used for more than 5 years, improper use, 2-3 years battery life is attenuated.

The service life of the ternary lithium battery is as high as 1.2 million kilometers, making it the first choice for potential buyers of electric vehicles. In terms of quality assurance, BYD electric car warranty for 6 years / 150,000 km (non-operating car), power battery cell lifetime warranty (non-accidental damage), confidence in the reliability of their products can be seen.

In theory, the life of a ternary lithium battery is 2,000 cycles of charge and discharge. We count as one charge per day, and it can last for 10-8 years or even ten years. However, there is still a difference between the use and the theory. If 1000 cycles of charge and discharge are performed, the ternary lithium battery has been attenuated by 50%, which means that the full charge can only run half of the original mileage.

The life of a new energy vehicle ternary lithium battery is generally measured by the number of battery cycles. The state has some laws and regulations on battery life, that is, when the power battery capacity is reduced to less than 80%, it is necessary to carry out forced recovery and continue to use the ladder.

Calculated in 52 weeks a year, you need to charge 104 times a year. If you assume that the service life of BYD ternary lithium battery is 1000 times (the specific number can be consulted BYD manufacturers), according to the conditions of use we set, basically, The vehicle life is 10 years.
