As we all know, in addition to the upgrading of electronic products, the battery life is also the biggest factor affecting the service life of electronic products.
The same goes for trams.
Everyone still remembers the Tesla Model S back then, the price of one million once made people think that Musk was crazy, but now the second-hand car ** is less than 200,000, Musk is not crazy, crazy is a group of car owners.
And the Mercedes-Benz S-class, which costs millions of dollars for the same age, can still be sold for 500,000 now, which is the gap.
Therefore, when buying a tram, don't consider the value retention rate, that kind of illusory thing does not belong to the tram owner.
Nowadays, the attributes of electric cars are more and more biased towards electronic products, as long as they are electronic products, they will be subject to the upgrading of hardware and the service life of batteries.
The running speed and experience of an Apple 4s can never be compared to the most ** Apple 15Pro, and the tram is the same, artificially treating the tram as a consumable that can be eliminated at any time, weakening the attributes of its tools, which has led to the tram being miserable in terms of value retention.
In addition to some outrageous situations and models with collectible value, there are very few used cars ** more expensive than new cars**, even if you just land and sell them, at least you have to lose a tax money, and the tram is even more so, and the models that have been cut in half for a few years abound.
Today's battery technology has not made breakthroughs for a long time, whether it is a solid battery or a liquid battery, the number of charging and discharging seriously limits the service life of the battery, many people in order to achieve the best battery use state, every day as strict operation of charging and discharging, what can not be fully charged at one time, what power is less than 10% and then charged, etc., so cumbersome and careful, I don't know what the original intention of buying a tram is.
And there is a fatal problem with the battery, that is, the power of the power after the age of the cliff attenuation, just like the design, such as ten years, for example, 8 years, as long as this period, the battery power will appear cliff attenuation, no matter how you maintain, 80% of the power will force you to replace the battery, the cost, is simply terrifying.
Take Tesla as an example, the ** of replacing the battery is from 120,000 to 240,000, which is higher than that of the second-hand car.
If the tram wants to maintain its value, it is not solved by increasing the life-threatening heap range of the battery pack, but can only wait for the battery to make a breakthrough, presumably then it is the time for the tram and the oil car to compete.
