Not long ago, Japan's leading position on the world's motor stage was successfully seized by Huawei. The performance of motors independently developed by Huawei has reached unprecedented heights. Among them, Huawei DriveONE, which can reach a maximum speed of 25,000 rpm, is currently available in the Zhijie S7. It accelerates from 0 to 0 to 100 rpm in 3.3 seconds, breaking the latest speed record for mass-produced motors.
Tesla CEO Elon Musk once predicted that Huawei is currently the only company that can truly threaten Tesla’s technology, and the capabilities Huawei has demonstrated are just the tip of the iceberg for the time being.
Huawei has been researching and developing electric vehicles for some time, and its motor technology is constantly being upgraded and optimized. The 25,000rpm motor design shows that Huawei has made certain breakthroughs in motor design and manufacturing. From the perspective of the main drive motor market for new energy vehicles, not many can truly achieve mass production of 20,000rpm motors. Most of them are in the research and development stage and need to be improved.
For example, the 2023 Tesla Model S Plaid is considered the fastest mass-produced electric car on the planet, with an acceleration of 100 kilometers in 2.1 seconds and a top speed of 322km/h. However, the maximum speed of the motor of Tesla Model S Plaid is only 20,000 rpm, which means that the speed of Huawei motor is 20% higher than that of Tesla.
The motor is the core component of a smart car, which determines the car's power, speed, efficiency, safety and comfort. A good motor is like a good heart, which can make the car run faster, use more energy, be safer and more comfortable.
In fact, the development process of Huawei DriveONE motor is very difficult. The first is the problem of materials. The rotor is most affected by high speeds. At ultra-high speeds, centrifugal force will cause its deformation. Therefore, the structure of the rotor is not as easy to be drawn by humans. It is necessary to rely on software and simulation to design the structure.
The second bigger problem is heat dissipation. The reason why Huawei's motor is called a "super motor" is because it needs to solve the problem of gear shafts and bearings that match the rotor. In addition, the problem of heat generated when the rotor operates at high speed must be solved, and the heat dissipation function is another major difficulty.
However, after rigorous calculation and testing, the efficiency of this motor has reached an astonishing 98%, so the above two major problems have been completely solved. And what is the concept of 98% efficiency? If you want to understand it more intuitively, you can understand it like this. A generator with the same power generation capacity used to be enough for 10 households, but after improving efficiency, it can be used by 20 households. It is simply an innovation in the energy field!
At the same time, Huawei's DriveONE motor is also very smart. Through artificial intelligence and cloud computing technology, Huawei's motor can analyze factors such as road conditions, driver's habits and needs in real time, and provide optimal power output and control strategies. This intelligent motor can make driving smoother, more comfortable and safer. For example, when driving on the highway, the motor can automatically adjust power output according to vehicle speed, road conditions and other factors to maintain a stable driving speed and reduce the driver's operating burden.
Huawei not only develops motors, but also invests in smart car systems, smart cockpits, smart connectivity and other fields, hoping to build a smart car ecosystem so that cars can become more than just a means of transportation. Become a good smart travel partner for mankind.
Huawei’s grand vision has been recognized and supported by many car manufacturers, such as Chery, BYD, Changan, Geely, etc. They have chosen to cooperate with Huawei and use its motors and other technologies to build smart cars. From the sales and attention of some models Judging from the scale, Huawei has won widespread praise from consumers.
