Orin chip computing power
The focus is undoubtedly the et7 of Weilai: Weilai's first intelligent electric flagship car with automatic driving ability. Weilai officially defines it as a car "born for automatic driving". So how strong is et7's automatic driving ability? First of all, let's understand the basic performance of et7: the maximum power of the new car is 480kw, the maximum torque is 850n · m, the drag coefficient is
0.23cd, and the 100 km acceleration is 3.9 seconds. The whole system is equipped with air suspension and 4D intelligent body control as standard
with such strong computing power, et7 is equipped with 19 safety and driving assistance functions of NAD as standard. The complete functions of NAD will adopt the service subscription mode of monthly rent, adaas (AD as a
Service), and the service fee is 680 yuan per month. Although we are very excited, the delivery of et7 will not start until the first quarter of next year, and the delivery of 150kwh battery pack will not start until the fourth quarter of 2022. Therefore, in such a long period of time, whether et7 can keep ahead in the fierce competition of new car brands still depends on the achievements of other students
Do you think the operation logic of buying Weilai et7 and digging bitcoin at home can be realized? It's a real talent. It costs 380000 Yuan to buy a car. It's 2000 yuan a day. It's 190 days. How about buying one? However, you change the power five times a day,
let's not say whether this car has the strength to compete with BMW 7 series, the parameters displayed are very attractive, such as super large size and wheelbase, 150 kwh super large battery, super fast acceleration performance and so on. However, one of the most interesting chips is the strongest chip in the field of electric vehicles and even electronic procts
according to the description, this chip is from NVIDIA Orin, which adopts 7Nm manufacturing process. In order to make the car engine system have enough chips, Weilai et7 suddenly crams four chips, which is equivalent to four super powerful CPUs installed in a computer. The single-chip computing power of NVIDIA Orin is 250tops, and the highest computing power is 1016tops. At present, the computing power of a bitcoin miner is about 100tops, that is to say, the computing power of a Weilai et7 is about 10 miners. This makes many friends who are obsessed with mining smell the breath of money
the maximum power of Weilai et7 chipset is about 3500W, that is, it consumes 3.5kwh of electric energy in one hour and 84 kwh of electricity in 24 hours a day. Et7 can support at least 40 hours with a 150kwh battery. Coupled with the free electricity exchange policy launched by Weilai, the electricity charge is almost free. You can go to the power station to replace a fully charged battery in less than two days. With the income of more than 2000 yuan a day, 365 days a year, you can earn 730000 yuan. After decting the price of 380000 vehicles, you can recover the cost in half a year. So how good it is to drive new energy vehicles and directly mine them

The algorithm and software architecture of
nad can make full use of Adam's powerful computing power. Two main control chips are responsible for the calculation of NAD full stack algorithm, including multi scheme mutual verification perception, high-precision map, multi-source combination positioning, multi-mode prediction and decision-making. Sufficient computing power of full stack algorithm makes nad more, faster and more accurate in dealing with complex traffic scenes
In addition, NiO Adam has independent and complete rendant backup chip, and the power supply, image and main control system of the whole supercomputing platform are all hot backup design, which is safe and reliable. As the next generation of automatic driving scheme, learning ability and personalized ability are the foundation of the advancedIn September of this year, we @ Gedian experienced the function of Weilai NOP (navigation on pilot). After Tesla FSD (NOA), this is the second auxiliary driving function that can automatically enter and exit the gate, change lanes and overtake based on the navigation planning route
NOP has been pushed to users in the form of FOTA, supporting all models of Weilai. Although es8 is "old fashioned", its built-in mobileyeq4 chip's computing rendancy can fully meet the needs of NOP
when it comes to advanced auxiliary driving, in addition to high-definition cameras and various radars, chips are the most important and the most difficult part for car companies to overcome. At present, in addition to Tesla's self-development, Mercedes Benz, BMW, Weilai and Xiaopeng all choose purchased chips. There are also many ADAS manufacturers that can provide such chips, such as Mobileye, Bosch, Texas Instruments and NVIDIA. When you see this, someone may ask:
"isn't NVIDIA the one that makes graphics card GPU?"

With super enrance, can Weilai et7 compete with Tesla
et7 is equipped with the latest NAD (NiO autonomous driving) technology, based on NiO Aquila ultra sensing system and NiO Adam ultra computing platform, it will graally realize the point-to-point automatic driving experience in high-speed, urban, parking, power on and other scenes
it can be said that this car includes full stack automatic driving technology capabilities including perception algorithm, map positioning, control strategy and underlying system
NiO Adam is equipped with four NVIDIA drive Orin chips, making et7 the first mass proction vehicle carrying NVIDIA drive Orin in the world. Adam has 48 CPU cores, 256 matrix operation units, 8096 floating-point operation units, a total of 68 billion transistors
Such performance features as
have a higher matching degree for automatic driving technology, so NVIDIA has won the favor of many companies involved in automatic driving technology. Volvo, man, sharing platform didi travel and Uber in the field of commercial vehicles, as well as automobile parts enterprises in Mainland Germany are all partners of NVIDIA
at the end:
the birth of Orin chip solves two major problems in the development process of automatic driving: compatibility and safety, which reflects not only the company's continuous pursuit of technology, but also a responsible attitude for customers, partners and society. Maybe after "Sea King", we will meet "Iron Man", "Hulk" and other different superheroes, but the same thing is that they will all play an important role in the progress of human society and technological development

Yes , when the U.S. stock market opened on the evening of January 11, Weilai's share price reached a new high, and its market value exceeded $100 billion . Based on "intelligent driving + intelligent hardware", Weilai will continue to iterate and increase its volume at both ends of software and hardware. CICC will maintain Weilai's instry rating and adjust its net profit forecast to 330 million yuan in 2022
in addition, CICC expects that Weilai's hardware profit will be RMB 9.2 billion in 2025, which is 30 times the PE valuation; Software revenue was 16.3 billion yuan, 40 times PS valuation, equivalent to 650 billion yuan. The revenue of car service business is 5.1 billion yuan, which is estimated at 20 times of PS. The total price is RMB 10300 million, and the target price is US $103 in 2025

extended information
Weilai released the new car benchmarking BMW 7 Series:
on January 9, on the annual NiO day, Weilai released its fourth mass proction model and the first car et7, equipped with 150kwh solid-state battery pack NEDC, with a driving range of over 1000km. The starting price of the model before subsidy is 448000 yuan, which is expected to be delivered in the first quarter of 2022
Li Bin, founder, chairman and CEO of Weilai, introced that et7 has applied the latest Weilai automatic driving technology NAD (NiO autonomous driving), equipped with the newly released hypersensitive system Aquila, supercomputing platform Adam, as well as the subsequent announced automatic driving algorithm and automatic driving vehicle platform, and will graally realize automatic driving in high-speed, urban, parking, power change and other scenes
