How many kilometers can Tesla battery use?

The official data of Tesla's endurance is 450,000 to 600,000 kilometers. In fact, the battery of electric vehicles is not so fragile at all. Domestic policy stipulates that electric vehicles should provide the battery with a warranty of 8 years or10.5 million kilometers. During the warranty period, the battery loss can't exceed 30%, which means that during the warranty period stipulated by the manufacturer, the owner doesn't have to worry about the battery life at all. More details are as follows: 1. At present, there are three kinds of batteries for electric vehicles: Ni-MH battery (mainly used for plug-in hybrid vehicles of Toyota), lead-acid battery (with a life of less than three years) and lithium battery (including lithium iron phosphate battery and ternary lithium battery). 2. Pure electric vehicles use lithium batteries, taking BYD and Tesla as examples. BYD uses lithium iron phosphate battery, which has long service life, good safety and high charge-discharge rate, but the energy density of the battery is relatively low, which means that more battery units are needed for the same cruising range, which increases the weight and cost of the car. Tesla uses ternary lithium batteries with good consistency, more mature production technology and high energy density. The same number of batteries store more electricity. 3. In terms of battery life, the lithium iron phosphate battery can be cycled more than 2,000 times and can be used for 5-6 years once a day. However, what I want to say here is that cycling once means that the battery is fully charged and then completely discharged. In daily use, it is often unnecessary to wait until the battery is dead. For example, the daily trip is from full charge to 75%, which is equivalent to using up a cycle in four days. 4. If the ternary lithium battery is charged and discharged more than 800 times in actual use, it can be used for at least ten years if it is also calculated according to a four-day cycle. If calculated according to the cruising range, ternary lithium battery electric vehicles can generally run180km in a complete cycle, and the total number of 800 cycles can reach140000km.
