The rise of electric vehicles has brought lithium batteries into people's vision. People pay more and more attention to the battery, the capacity of the battery, the life of the battery and the safety of the battery. On the whole, how long does lithium battery last?

Generally speaking, the life span of lithium battery is decided at the moment when the battery is made into finished product, taking the ternary lithium battery as an example. From the perspective of cell material, the cycle life of battery should be 1500 to 2000 cycles. If the new energy vehicle can run 500km with one charge, it means that the battery life of 300000-500000 km will be used up. According to the calculation of one to 20000 km a year, an electric vehicle can run for more than 10 years, but the cycle of replacing a car for ordinary people is difficult to exceed 10 years, so the lithium battery life of electric vehicles can basically meet the needs of most people 。

However, the battery is not in this ideal state in the actual use process, and the nominal capacity at the end of battery life is generally considered to be 80%. So if the nominal capacity of the battery is less than 80%, we think that the battery needs to be replaced. If our battery is used normally for more than six years, the nominal capacity will not be less than 80%. So now the battery life of electric vehicles is generally between six and ten years, which can basically meet the needs of ordinary people, provided that the range of your electric vehicles is relatively long. If the original endurance mileage is not ideal, in the attenuation, it may not meet the needs of car use in life, it will feel very inconvenient.

So in a comprehensive consideration, when buying electric vehicles, try to choose the ones with a slightly longer endurance mileage, which can basically ensure that the use of electric vehicles will not be affected by batteries within six years.
