What should I do if the lithium battery of an electric vehicle has passed the warranty period?

At present, some electric vehicles on the market have a warranty period of 100,000 kilometers in 5 years, and a few have reached 150,000 kilometers in 6 years. Although it is already very long. But if the warranty period expires and the battery function is severely attenuated, and the battery life will change from 200 kilometers to 100 kilometers, it is indeed a big problem. If the customer is asked to pay for the battery pack, the cost is too high. But if you don’t change the battery pack and spend hundreds of thousands of dollars to buy an electric car, it really becomes a short-distance transportation similar to that of a scooter in the late era. After prolonged use, it is normal for the battery function of electric vehicles to decrease to a certain extent. At present, the state stipulates that during the warranty period, the battery's function attenuation cannot exceed 20%. Otherwise, the manufacturer will replace the battery for the car owner free of charge. So, is it to replace the entire battery pack? No, the battery pack is composed of many battery cells, and its functional principle fits the barrel theory. A problem with one battery cell will affect the function of the entire battery pack. Therefore, the manufacturer will replace the defective battery cell free of charge, allowing the battery pack to rehabilitate its high functions. So, what should I do if the functions of electric vehicles decline after the warranty period? He said that the state currently stipulates that manufacturers are responsible for the recovery of used batteries, but since electric vehicles have only been on the market for one or two years, there are no detailed rules on how to recover the used batteries and at what price. In recent years, the functions of power lithium-ion batteries have improved, but the cost has been declining. For example, in the past few years, the battery cost accounted for 50-60% of the cost of an electric car, but it has now dropped to 40%, and it is expected to drop further in the future. In this case, after the warranty period, even if the battery function is severely attenuated, the car owner replaces the new battery pack with the used battery, and the estimated cost is also reduced. But based on this alone, it is difficult to eliminate customer concerns. It seems that when choosing electric vehicles, the longer the warranty period of power lithium-ion batteries, the better. my country will usher in the era of decommissioning of power lithium-ion batteries around 2017, and there has been a rapid increase year after year. It is estimated that in 2020, the cumulative scrap volume of lithium-ion batteries for electric vehicles in my country will reach 120,000 to 170,000 tons. However, at present, there is still no good way to deal with the recovery and solution of waste batteries of electric vehicles in China. This is indeed a big problem, which will not only affect customers' confidence in buying electric vehicles, but also cause severe environmental pollution from waste batteries.
