How long can a set of lithium batteries for electric vehicles last? Why can some people's lithium batteries last 2 ~ 3 years, and even some can last 3 ~ 5 years? In fact, the service life of most lithium batteries is planned to be about 1000 times (generally ternary lithium battery materials), that is, 3 ~ 4 years.

 

How many years is the service life of lithium battery for electric vehicle? How many years can the lithium battery of electric vehicle last? I believe most customers have heard that the life of lithium battery is "1000 times", 1000 times of charge and discharge. Beyond this number, the battery will "die forever". Many friends want to extend the life of the battery.

 

Every time the battery is completely discharged, it will be charged. Does this really extend the life of the battery? The answer is No. The life of lithium battery is "1000 times", which refers to not the number of times of charging, but a cycle of charging and discharging. A charging cycle means that all the power of the battery changes from full to empty, and then from empty to full, which is not equivalent to charging once.
