What should I do if the electric vehicle lithium battery has passed the warranty period and its performance declines?

How to deal with the deterioration of the warranty performance of the lithium battery after the electric vehicle is indeed environmentally friendly, but there is a big problem: after the battery has passed the warranty period, the battery function is attenuated or there is a problem, what should I do? Analysis for everyone What if the function of the lithium battery of an electric vehicle is attenuated after 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 a warranty period of 6 years to 150,000 kilometers. Although it has been a long time. But if the warranty period is too long and the battery range is increased from 200 kilometers to 100 kilometers, then there is a problem. If the customer spends money to replace the battery pack, the cost is too high. But if you don't replace the battery pack and spend hundreds of thousands of dollars to buy an electric car, it will really become a short-distance transportation similar to the elderly car. After a long period of use, it is normal for the battery function of an electric vehicle to decay to a certain extent. The country now 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, replace the entire battery pack? No, the battery pack is composed of many battery cells, and its functional principle is consistent with the barrel theory. If a single battery has a problem, it will affect the function of the entire battery pack. Therefore, the manufacturer will replace defective battery cells free of charge, so that the battery pack can be restored to high functionality from the beginning. So, what about the functional decline of electric vehicles after the warranty period? He said that my country now requires manufacturers to recycle used batteries, but because electric vehicles have only been on the market for a year or two, how to recycle used batteries and There are no detailed regulations on the price of recycling. Nowadays, power lithium-ion batteries are getting better and better, but the cost is declining. For example, in the past few years, battery costs accounted for 50-60% of the cost of electric vehicles, but it has now fallen to 40%, and it is expected to fall further in the future. In this way, after the warranty period, even if the battery function is severely degraded, it is estimated that the cost will drop if the owner replaces the used battery with a new battery pack. But this alone is difficult to reassure customers. It seems that when choosing an electric car, the longer the warranty period of the power lithium-ion battery, the better. my country will usher in the era of power battery retirement around 2017, after which it will rise rapidly year by year. It is estimated that by 2020, the scrap volume of lithium-ion batteries for electric vehicles in my country will reach 120,000 to 170,000 tons. However, there is no good solution for the recycling and disposal of electric vehicle batteries in our country. This is indeed a big problem, which will not only affect consumers' confidence in buying electric vehicles, but also cause serious environmental pollution from waste batteries.
