New energy vehicles Recently, dear friends have inquired about the current situation of the booming new energy vehicle market and whether it is suitable to buy pure electric vehicles. In the face of this inquiry, the author only asked them rhetorically: "How many people have mentioned to you the battery life and replacement cycle involved?" ”
In fact, many consumers who own pure electric vehicles choose to avoid talking about the problem of battery replacement, why is this?
The first factor is that as early as nine years ago, the relevant ** department issued a clear regulation: car manufacturers need to promise consumers to provide consumers with a quality guarantee of at least eight years and 120,000 kilometers of three-electric systems. Nowadays, many manufacturers have launched preferential policies for the lifetime warranty of the three-electric system. Therefore, if you happen to encounter a failure during the warranty period, you can easily solve the problem by simply driving your car to an officially authorized 4S store for after-sales service.
However, what if a collision accident occurs? Don't worry, motor vehicle commercial insurance will solve your worries. Some people think that the insurance cost of electric vehicles is more expensive, but in fact, the cost of battery insurance is the core of determining the overall premium level, whether it is due to impact or spontaneous combustion and other causes of battery damage, you can get corresponding compensation through insurance. If the battery pack is deformed due to an accident, the insurance company will be responsible for repairing it appropriately. If the battery pack has not lost its repair value, the insurance company will replace the battery with a new one. Conversely, if the residual value of the vehicle itself is insufficient to cover the cost of the required battery, the insurance company will treat the vehicle as a total loss, depending on the circumstances.
Some friends may ask, if the mileage is long, the battery will fail before the service life, can it be replaced free through the warranty process? Before understanding this problem, we need to realize that ternary lithium batteries perform well in the 80% charge-discharge deep cycle life test. Before 1200 cycles, the battery capacity decays very slowly, and at 1200 cycles, it is only 14The 3% capacity loss has only since begun to show a more pronounced downward trend. Based on the calculation of 300 kilometers on a single charge, about 360,000 kilometers can be driven in 1,200 cycles! For the average family, the annual mileage is usually only about 20,000 kilometers, so even after 18 years of use, the battery is still in good condition. Therefore, there is no need to worry too much about battery attenuation.
Of course, there are exceptions, and not all cases are self-incurable: once you buy a car from an emerging brand with a bad reputation, you will have to find a solution to the problem when you are at risk of bankruptcy from the original 4S store.
For example, a car owner surnamed Li once purchased a certain pure electric model, but he did not know that the battery had a serious failure after less than two years of use. After in-depth testing by the after-sales department, it was found that only the replacement of the entire battery pack could completely solve the problem. Regrettably, however, the car manufacturer has declared bankruptcy, and it is no longer possible to seek free maintenance with the warranty system, and users have to pay up to 80,000 yuan in maintenance costs out of their own pockets to ensure the normal operation of the vehicle.
By searching the car quality network, it can be seen that such complaints are not uncommon. However, in general, the vast majority of electric vehicle owners who enjoy the manufacturer's warranty are worried about battery quality problems. Even if the battery performance of the older car and the longer mileage is reduced, there are still lucky people who can enjoy the free replacement decision provided by the manufacturer. For example, some owners of the early model Tesla Model S, due to their more intense usage habits, often use high-power fast charging mode, after six or seven years, the mileage has reached an astonishing 150,000 or even 200,000 kilometers, and the battery will inevitably undergo significant decline. However, the manufacturer's commitment to a warranty policy of up to eight years and a mileage of up to 200,000 kilometers has led to numerous cases of successful battery replacement during this period.
Whether the process is cumbersome or not depends mainly on whether the quality inspection results show that the battery has deteriorated excessively. If it is confirmed that the battery disease is real, the 4S store will negotiate with the manufacturer to replace the goods to ensure that after the timely delivery of the goods, the owner only needs to go to the store to sign and pick up the car to complete all the procedures. No matter what brand of vehicle you drive, as long as it is a well-known large manufacturer, they usually implement a warranty policy without reservation, and provide owners with a worry-free battery replacement service.
