According to the data, about 6.4 million vehicles were sold worldwide in 2021, and the penetration rate of electric vehicles reached 20% in China.
However, the fire returns to the fire, the hot selling returns to the hot sale, and the biggest obstacle to everyone buying an electric car is the endurance, as well as the charging problem. Because the endurance is too short, so that consumers can not go far, and charging is inconvenient, in order to charge a battery may have to queue for several hours, but also let consumers discouraged.
Of course, these two problems are actually a problem, if the endurance of electric vehicles can be raised longer, even longer than fuel vehicles, then the problem of inconvenient charging can be effectively alleviated, after all, you can drive a long distance to charge once, such as long-distance can also drive a round trip, and then go home and then rush again.
So in the past many years, many new energy vehicle companies, EMU battery companies, in fact, are solving the problem of batteries, first of all, to improve battery capacity, improve endurance, followed by improve charging efficiency, such as power exchange.
Recently, the news came out that Tesla's 4680 battery is going to be officially mass-produced, and with the blessing of this battery, Tesla's endurance is expected to exceed that of traditional fuel vehicles.
Before the 4680 specifications, Tesla has used the two specifications of 1865 and 2170, and may not understand the numbers very well, in fact, it is very well understood, the front two digits represent the diameter of the battery, and the back two represent the height, unit mm. 4680 means that the diameter is 46mm and the height is 80mm.
Compared with the previous two generations, the 4680 battery actually has only one advantage, that is, the battery density is higher, allowing electric vehicles to last longer, while reducing manufacturing costs.
According to the previous test data, ModelY can increase its cruising range by about 20-30% after replacing the 4680 battery, which means that in real driving, which is a high-speed of 120KM/H, driving more than 600KM may not be a problem.
The general fuel vehicle, if the fuel tank is below 60L, may not actually reach this level.
Some time ago, the boss of a new car-making force spoke heroically: "I don't understand at all, why are there still people buying oil trucks?" Is it to smell some gasoline? ”。 Considering that many companies are now promoting the mass production of 4680 batteries, if the 4680 batteries are fully mass-produced, they can indeed be so proud.
