Before, some netizens photographed Semi pulling his Tesla to deliver the goods in Fremont. Recently, Musk confirmed in an interview that the commercial version of Semi has been tested and can run 1,000 kilometers with a full load of 40 tons. After taking traditional passenger cars on the beach and reaching the top of the world’s number one car company, the history of commercial vehicles will probably be rewritten by Tesla! This article from the micro-channel public number: Xinzhiyuan (ID: AI_era)< /span>, source: electrek, editor: Bai Feng, original title: “Tesla SemiTruck with a full load of 40 tons starts road test! Daimler Trucks is responsible for 1,000 kilometers of battery life People call: Violation of the laws of physics, title picture from: Visual China
The truck can’t use batteries and must burn oil?
Musk said that there was nothing like that.
This CEO from Mars is really a walking billboard. No, he is endorsing Tesla’s truck Semi.
A full load of 40 tons can run 1,000 kilometers, Semi pulled his own Tesla on the road to test
Musk said in an interview, “Assuming a truck has to pull 40 tons of cargo, I think 500 kilometers of endurance is quite easy to achieve, frankly, it is easy. If you want, for long-distance truck transportation , SemiTruck can easily reach 800 kilometers, while the heavy-duty truck with the latest 4680 battery can reach 1,000 kilometers.”
Pull up Tesla to go shopping. The 1,000km battery life version has started prototype testing in Fremont, California!
Semi drags Tesla to go shopping
Regardless of China or the United States, 1,000 kilometers of battery life can meet 99% of road transportation needs.
Recently, Tesla’s market value once approached 500 billion U.S. dollars, which is more than twice that of the “traditional car overlord” Toyota, and has successfully reached the top of the world’s number one car company.
The market for new energy vehicles, especially smart electric vehicles, has also risen, and domestic brands such as Weilai, BYD, Xiaopeng and Ideal have also entered the top 15 in market value.
The electric passenger car market is surging. As a top player in electric commercial vehicles, why can the battery life of Semi improve by leaps and bounds, from the previous 500 kilometers, 800 kilometers, to 1,000 kilometers?
The biggest hero of battery life 4680, the person in charge of Daimler Trucks: Violation of the laws of physics
In 2018, Musk presented the Semi truck for the first time and claimed that the production version will have a battery life of more than 600 miles (nearly 1,000 kilometers).
Many people in the industry think it is blowing, and there are indeed many electric car manufacturersThe advertised cruising range is under ideal conditions, and without similar testing by NEDC, it will be “sleepy” on the road.
At the time, Musk said that his Semi-electric semi-trailer truck can drive 500 at a full load of 80,000 pounds(about 36 tons) Miles, the cost is only $180,000.
The total weight of Semi will be in the range of 40 tons, instead of actually pulling 40 tons of cargo, because according to the US road and transportation regulations, the total weight of this class of trucks is limited to 88,000 pounds.(40 tons).
Many people think this is a fantasy. Even Martin Daum, the head of Daimler Trucks, (Martin Daum) said , “Tesla Semi violated the laws of physics. If it is true, it is surpassing us.”
Today, two years later, Tesla’s Semi has not yet been launched, and commercial vehicle giant Daimler has been far behind.
Daimler is also trying some electric truck projects, such as the FUSO eCanter, but the mileage is only 100 kilometers(62 miles), and the load capacity There is only a poor 3.5 tons, and there is a larger all-electric electric truck with a load of 26 tons, a battery pack of 212 kWh, and a driving range of about 125 miles, which is not in the same order as Semi.
< /p>
FUSO lost in terms of appearance
For trucks, battery life is only one aspect. The most important thing is how much cargo it can load, because more cargo can increase profitability.
The battery pack of electric vehicles increases the truck’s own weight, which restricts the mass production of electric trucks.
Musk said that the production version of Semi may lose one ton of cargo capacity due to the battery, which does not affect the overall situation.
“You can basically load the same cargo as diesel trucks. We think there may be a difference of 1 ton. At this point, we can save about 1 ton compared with trucks of the same weight.(probably the left) goods, but in the long run, this weight will be insignificant”.
Musk also confirmed that Tesla Semi will use Tesla’s new 4680 battery pack, which is exactly the new design announced by Tesla at the Battery Day event, revealed from the press conference According to the information, the energy density of 4680 can reach 300wh/kg.
At the battery level, this energy density is sufficient for the needs of an electric truck.
4680 battery costs have dropped sharply, and mass production of Semi electric trucks is just around the corner
The size of the Tesla 4680 battery is 46X80mm, the battery is larger, and the energy density is five times that of the previous battery.
Like other large-volume battery designs, the 4680 also faces the problem of thermal management. However, the cylindrical 4680 directly takes off the “clothes” to dissipate heat! At the same time, the cost per kilowatt hour of 4680 was reduced by 14%.
Demonstration of new battery
To be equivalent to the cost of a fuel car, the battery production cost per kilowatt hour should be reduced to about $100. Tesla’s 4680 is very close to this goal.
In addition, 4680 also uses laser technology to remove the electrode tabs (tabs) to further alleviate the phenomenon of battery overheating.
4680 uses new materials instead of complex post-processing to design batteries that can withstand anode loss, so that the anode alone can reduce the cost per kilowatt hour by 5%.
This new battery pack has been put into production at a pilot plant in Fremont. I believe that the production capacity is not a big problem, because the production process of Tesla’s battery factory has undergone revolutionary changes, and the current battery production looks more like filling Coke.
Musk estimates that it will take Tesla about a year to achieve a 10GWh capacity ramp.
Currently, Tesla’s short-term goal is to reach 100GWh per year by 2022 and 3TWh per year by 2030.
This production efficiency plus the capacity of the new battery, Musk estimates that by 2022 the cost per kilowatt hour will be reduced by 32%.
The battery pack will also adopt a new combination method. In the future, the battery pack will directly become a part of the frame, further weakening the concept of the module, and the battery core is directly integrated into the body. The next-generation car will basically have a battery life of 1000km.
With the blessing of the 4680 battery pack, SemiTruck mass production is “just around the corner.”
SemiTruck may rewrite the situation in the electric commercial vehicle industry. Musk believes that internal combustion engine vehicles will soon embark on the road of steam engines.
Industry experts have always been conservative and skeptical about the electrification of commercial vehicles, but some senior electric vehicle investors said:
“Smart electric vehicles and smart travel are the biggest structural opportunities after smartphones and mobile Internet. There will be trillion-dollar companies in China and the United States. There will be short-term bubbles and various ups and downs in the market. The difference in market value between a good company and a bad company will be 2Over 0 times, companies that focus on products will win out. The current market is a bit like a digital currency, the market will grow when it comes, and vice versa. “
Is the electric car shaping a new trillion-dollar business or a big bubble that can be broken? let us wait and see!
