How long is the service life of lithium batteries for electric vehicles?

I believe that most consumers have heard that the life of a lithium battery is 1000 times, 1000 times of charging and discharging, beyond this number of times, the battery will die, many friends in order to be able to extend the battery life, every time the battery is completely consumed Charge it when it is exhausted. Does this really extend the life of the battery? The answer is not fixed. The lifespan of a lithium battery is 1000 times, which does not refer to the number of times of charging, but a cycle of charging and discharging. A charging cycle means the process of using all the power of the battery from full to empty, and then from empty to full. This is not the same as charging once. For example, a lithium battery uses only half of its power on the first day, and then charges it slowly. If it is still the case the next day, that is, use half of the charge, and charge it twice in total. This can only be counted as one charging cycle, not two. Therefore, it may usually take several times to complete a cycle. Every time a charging cycle is completed, the battery capacity will decrease a bit. However, this amount of power is very small. High-quality lithium batteries will still retain 80% of the original capacity after being charged for many cycles. Many lithium-powered products are still used as usual after two or three years. Of course, the lithium battery of an electric vehicle needs to be replaced after the end of its life. The so-called 500 times means that the manufacturer has achieved about 625 charging times at a constant depth of discharge, reaching 500 charging cycles. Due to various influences in real life, especially the depth of discharge during charging is not constant, 500 charging cycles can only be used as a reference for the life of a lithium battery.
