When many people discuss pure trams, they will always hear the view that although new energy vehicles are charged and save money than refueling, due to the immature battery technology, the cost of replacing batteries after a few years is comparable to the price of half a car. This view has been circulating in the car circle for a long time, but is this really the case?
Recently, Andy Slye, the first owner of Tesla Model 3, used practical actions to verify that this view is not true. He said that he purchased the Model 3 long-endurance after-drive version four years ago, and has traveled a total of more than 100,000 miles so far, which is roughly 160,000 kilometers under the domestic measurement unit, and the rated endurance of the vehicle is only 310 miles from the 310 miles when the car was originally purchased, and the full battery life is still 303 miles today, and the overall attenuation is only 2.2%.
Since the battery of Tesla Model 3 has only 2.2% endurance decay after 4 years of use, the owner is also very confident that he will not replace the battery in ten years.
In fact, around the world, the owner of the Tesla who personally "measured" Tesla's reliable endurance was most famous for a German named Hans Yoog-Gemingen. As early as 2014, shortly after Tesla debuted, he bought the Model S P85 model, and as of January 2022, the total mileage of the Model S he drove exceeded 1.5 million kilometers.
According to previous reports, he is the first user in Tesla's history to achieve the goal of 1 million kilometers of driving range, and in the whole process of using the car, his Model S P85 model has replaced the rear shock absorber once, 1 front axle, 1 touch screen, as well as 3 batteries and 4 electric motors.
The first of these batteries helped the vehicle travel more than 290,000 kilometers before the end of its life. The latest battery replaced at this stage still has 86% of the available power after driving more than 460,000 kilometers, which is enough to prove the "durability" of Tesla's battery.
It is worth mentioning that the Model 3 driven by Tesla owner Andy Slye mentioned at the beginning of the article is equipped with a 21700 battery pack, which is more advanced than the 18650 battery pack used by the Germans to drive the Model S 1.5 million kilometers before.
It is understood that Tesla is still working hard to develop its next-generation battery, that is, the 4680 battery. At present, Japan's Panasonic has decided to invest 80 billion yen to expand the battery factory this year, and will officially mass-produce Tesla 4680 batteries as soon as next year. At that time, presumably, Tesla models equipped with the new battery will get a more ideal endurance performance.
