What should I do if the performance of the electric vehicle lithium battery deteriorates after the warranty period?

What should I do if the performance degradation of lithium battery electric vehicles has passed the warranty? Many Grida fans asked Grida’s engineers that electric vehicles are indeed environmentally friendly, but there is a big problem: after the battery warranty period, the battery performance declines or becomes invalid. What should I do? Changing the battery is too expensive. If you don't change it, electric cars will become waste. What a loss. The reason for the doubt is: After six months or one year of use, the battery capacity of the mobile phone will be severely reduced, and it will even be unable to charge. This is especially true for electric bicycles. According to this reasoning, although the battery of an electric vehicle is a high-performance lithium battery, its performance will continue to decay over time. Although the manufacturer says that the warranty period for electric vehicle batteries is very long, consumers can ask the salesperson a question: What about the warranty period? Faced with this question, Grida engineers have no answer. At present, some electric vehicles sold on the market have a five-year warranty of 100,000 kilometers, and some have a six-year warranty of 150,000 kilometers. long time no see. But when the warranty period expires and the battery range increases from 200 kilometers to 100 kilometers, there is a problem. It is too expensive for consumers to pay for replacement. But if you don’t change the battery pack and spend hundreds of thousands of dollars to buy an electric car, it has really become a short-distance transportation similar to a classic car. Considering this question, Glida engineers consulted some new energy vehicle technicians, and they gave the following answers for your reference. Technicians said that after a long period of use, it is normal for the battery performance of electric vehicles to decline to a certain extent. At present, the state stipulates that the attenuation performance of the battery cannot exceed 20% during the warranty period. Otherwise, the manufacturer will replace the battery for the car owner free of charge. So, replace the entire battery pack? No, the battery pack consists of many battery cells, and its performance principle conforms to the barrel theory. There is a single battery problem, which will affect the performance of the entire battery pack. Therefore, the manufacturer will replace the defective battery cell free of charge to restore the high performance of the battery pack. So, how does the performance of electric vehicles degrade after the warranty period? He said that the current national regulations are that manufacturers are responsible for recycling used batteries, but since electric vehicles have only been on the market for one or two years, there are no detailed regulations on how to recycle used batteries according to what price. Glida engineers found that on December 30, 2014, four ministries and commissions including the Ministry of Finance jointly announced the 2016-2020 ``Pay attention to the promotion and application of financial support policies for new energy vehicles'' (hereinafter referred to as the notice), clarifying the automakers and being responsible for the main body Power lithium-ion battery recycling, responsible for power lithium-ion battery recycling. But there is no clear recovery price and other key information. Grida asked the technician: If a consumer asks you, 'What if your battery ages after the warranty period?' He also doesn't have a clear answer, because there are no specific regulations or standards. The question is who will bear the cost of replacing the battery. The good news is that the performance of power lithium-ion batteries has improved over the years, but the cost has fallen. 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 is expected to fall further. In this case, after the warranty period, even if the battery performance is severely degraded, and the owner replaces the old battery with a new battery pack, the estimated cost will be reduced. But this alone is difficult to reassure consumers. It seems that when choosing an electric car, the longer the warranty period of the power lithium-ion battery, the better. Wang Binggang, an expert on the National 863 Electric Vehicle Program, gave this suggestion: Most automakers now have warranty commitments, and the state also has requirements. The actual implementation status does not know what will happen. I think the quality of batteries is uneven, and it is difficult to say whether this promise can be realized.
