Analysis of the service life of lithium-ion battery for electric vehicles

Analysis of the service life of lithium-ion batteries for electric vehicles. Many people are entangled in the service life of lithium-ion batteries for electric vehicles. How long can a set of electric vehicle batteries last? Why do some people’s batteries last for 2-3 years, while some people’s batteries are scrapped after less than a year? How long is the life of an electric car battery? How many years can electric vehicle iron-lithium-ion batteries last? I believe that most consumers have heard that the life of a lithium-ion battery is 500 times, 500 times of charge and discharge, beyond this number of times, the battery will die. In order to extend the life of the battery, many friends are fully charged every time. Only charge when it is exhausted. Does this really extend the life of the battery? the answer is negative. The lifespan of a lithium-ion battery is 500 times, which does not refer to the number of recharges, but a cycle of charge and discharge. There are generally two types of electric vehicle batteries currently on the market: lead-acid batteries and lithium-ion batteries. The life of a lead-acid battery is defined according to the battery capacity attenuation to 30% of the original capacity. Generally speaking, it should be fully charged and discharged for about 300 times, and the lifespan is about one and a half years. If the riding distance is short, it can be used for about 3 years; lithium ion The battery has a strict number of recharges, usually around 1000-1200 times, and the life span is 3-5 years. However, the charging of lithium-ion batteries is the opposite of that of lead-acid batteries. They must be recharged after being used up. When the battery is not used for a long time, it must be fully charged once every two months to prevent battery protection and extend battery life.
