Do you know how long an electric vehicle lithium-ion battery can last?

I believe most consumers have heard that the life of a lithium-ion battery is 500 times, 500 times of charging and discharging, beyond this number of times, the battery will die, many friends in order to extend the battery life, every time the battery is completely consumed Only charge when it is exhausted, can this really extend the life of the battery? the answer is negative. 500 times refers to not the number of times of charging, but a cycle of charging and discharging. A charge-discharge cycle means the process of using the battery power from full to empty, and then from empty to full. This is not the same as charging once. For example, a lithium-ion battery uses only half of its power on the first day, and then recharges it. If it is still the case the next day, that is, use half of the charge and charge it twice, which 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 reduction in power is very small. High-quality batteries will still retain 80% of their original capacity after being charged for multiple cycles. Many lithium-ion batteries will still be used as usual after two or three years of use. Of course, the lithium-ion battery needs to be replaced when its life is reached. 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. Affected by real life, especially the depth of discharge during charging is not constant, so 500 charging cycles can only be used as a reference.
