Special report from Youche.com: On March 3, Aian released a new generation of high-performance integrated electric drive technology group - Quark electric drive, which can burst out strong power in a very small size, and the motor power The density is as high as 12kw/kg, which is 100 times higher than the industry’s 6kw/kg. A palm-sized motor can bring huge horsepower beyond the V8 engine! Achieving this breakthrough is no less than the chip industry fast-forwarding from the "28 nanometer" era to the "3 nanometer" era. Coincidentally, Tesla Investor Day officially announced its new generation of self-developed electric drive system, which will further reduce costs by reducing the use of materials such as silicon carbide. One side is pursuing ultimate cost control, and the other is pursuing extreme performance transcendence. Both parties seem to have formed two sets of logical and technological development routes. Picking off the unfinished fruits of Tesla, Aion has broken through the world-class problems of electric drive, ranging from common civilian applications such as balancing cars and drones, to high-precision fields such as "national treasures" aircraft carriers and space exploration. Motors play an indispensable role in them, but no matter which industry, they are pursuing motors with "small size and huge power". It can be said that the development history of motor technology is a history of continuous pursuit of ultimate power density. In 1900, Porsche launched a concept car using a small hub motor. However, due to the insufficient power density of the small-sized motor, the vehicle's top speed was only 35km/h, and ultimately it could only abort. Coincidentally, in order to achieve higher power density, Tesla's first model Roadster was originally designed to use a two-speed gearbox. However, due to various technical problems, it was ultimately unable to be mass-produced and the power density could not be improved. In fact, breakthroughs in motor power density have always been a world-class problem. Countless engineers and scientific research institutions are committed to improving its power density. There are successes and there are failures. Breakthroughs in power density face two major world problems. On the one hand, we need to consider how to achieve greater power output while maintaining the same volume. This requires exploring the space limits of the motor so that every point of the motor can unleash its maximum potential. At the same time, the power can also be increased by increasing the voltage. However, every 1V increase in voltage is a huge system-level project involving materials, processes, software, packaging, and safety; on the other hand, high-power output losses must be avoided, and the power that is finally increased should be avoided as much as possible in heat generation. Useless work. In the past 10 years of rapid development of the new energy vehicle industry, the industry's motor power density has increased from 2kw/kg to 6kw/kg. The emergence of Ionquark electric drive technology has greatly increased the motor power density to 12kw/kg, picking up the unfinished fruit of Tesla. Three first-of-its-kind technologies lead the transformation of driving methods. The Aian electric drive R&D team has been deeply involved in the field of power technology for more than ten years and has strong R&D strength. Focusing on the two core points of "high power density and low heat loss", we continue to carry out iterative technology development, thus accumulating nanocrystalline-amorphous super-efficiency motors, X-PIN flat wire windings, 900V high-efficiency silicon carbide, E-drive software, wireless A series of innovative technologies such as power interruption electronic shifting. The core of these are three forward-looking technologies: The world's first "nanocrystalline-amorphous" super-efficiency motor. With the development of permanent magnet synchronous motor technology, motor core loss is the main factor affecting the efficiency of the motor. The Aion Motor team innovatively developed from basic raw materials and electromagnetic principles, and designed a "nanocrystalline-amorphous" alloy material and batch preparation process; compared with the traditional iron-based silicon steel material smelting process, the cooling of nanocrystalline-amorphous materials The speed is as high as 1 million ℃/s, 1,000 times faster than iron-based silicon steel materials; it has the microscopic characteristics of disordered arrangement of atoms, no grains, and no grain boundaries. Its iron loss coefficient is much lower than that of iron-based silicon steel and other electrical steels. Aian innovatively applied this material to make the motor core, reducing the motor core loss by 50%, thereby effectively reducing the motor energy loss. The motor operating efficiency was increased to 97.5, the highest efficiency of the motor. reached 98.5. The industry's first X-PIN flat wire winding Aian combines its own patented X-PIN flat wire stator technology and carbon fiber high-speed rotor technology to increase the electric drive power by more than 30% while reducing the volume by 25%.
Based on the advancement of motor technology, future products will be miniaturized, lightweight, and have diversified travel forms. X-PIN carbon fiber high-speed motor technology has three national patents for unique platform winding solutions, which can achieve multi-platform compatibility in the power range of 70kW~320kW and the torque range of 220~450Nm. ? The world's highest 900V silicon carbide power module Aian is deeply involved in the construction of the SiC industry chain and develops its own packaging design. Breakthroughs have been made from four directions: chip layout, current sharing consistency, reducing chip switching delay, and laminated power circuit design. At the same time, combined with the innovation of all-silver precise low-temperature sintering process, the SiC module circuit noise inductance has been reduced by more than 50% and the thermal resistance has been reduced by approximately 25. The chip flow capacity is increased by more than 10%, and the power cycle life is increased by about 100%. Combined with the safe and reliable SiC chip drive and protection design, it gives full play to the high withstand voltage, high power density and high efficiency characteristics of silicon carbide, helping the Quark electric drive achieve a maximum full power operating voltage of 900V, a peak power of over 320kw, and a maximum efficiency of over 99.8 , ranking at the top level in the industry. A series of technical innovations of the Quark electric drive start from the details and constantly strive to achieve the ultimate perfection, thereby breaking through the contradiction of "large power and small size" and giving Aion's Hyper SSR and Hyper GT inherent The ultimate performance and ultimate space experience! Let Aian Hyper SSR achieve the world's fastest multi-motor acceleration to 100 kilometers in 1.9 seconds, and Hyper GT achieve the world's fastest single-motor acceleration to 100 kilometers in 4.9 seconds. Open your imagination to the future and make everyone an Iron Man with the Quark electric drive. This Quark electric drive breaks through the incompatible contradiction of "large power and small size" for the first time, allowing Aian's electric drive research and development to enter the "nano era" and creating a new world for Aian. The history of electric drive technology research and development has set a new milestone, which is also a microcosm of the take-off of China's new energy vehicle industry. As China's first car company to develop its own full-stack EV ICV, Aian has achieved many technological transcendences. Not only has it independently developed three original battery technologies: magazine battery, super speed battery, and sponge silicon battery, solving the three major industry pain points of safety, energy replenishment, and battery life in one fell swoop, it has also launched the "AEP3.0 Platform" and "Star Spirit Architecture" Waiting for Hyper Tec's new generation of high-end technology. Four years ago, Ion and Tesla were the only two car companies with pure electric platforms. Last year, Ion released a new generation platform AEP 3.0. At this investor day, the new generation platform promised by Tesla has once again jumped. Got the ticket. Although Musk released the third chapter of his secret ambition, the stock price plummeted during the event. The reason is that Tesla has grand ideals but insufficient details. It is a complete picture without enough new technology to support it. On the basis of full-stack self-research, Aian also established Ruipa Power Technology Co., Ltd., focusing on the research and development and industrialization of forward-looking power technology, comprehensively integrating R&D, intelligent manufacturing, sales, and services to create more and more extreme products. Power technology products lead industry changes. The advent of Quark electric drive has given people a richer imagination for future automobile forms. Perhaps in the near future, lightweight and powerful in-wheel motors can be mass-produced. By then, side parking can be as "domineering" as a crab, and even narrower road sections can easily turn in place, and can even accelerate submarines. The mass production of automobiles, flying cars and other automobile forms has been launched, bringing users a fantastic travel experience of "catch the moon in the sky and catch turtles in the five oceans". Of course, Quark electric drives are not limited to cars, but can also be used in many forward-looking fields to unlock more future smart life scenarios. For example, in the field of medical technology, quark electric drive can be used to make powered prosthetics, so that disabled people can also have the ability of normal people; wearable machines can become part of the human body, and everyone can be an Iron Man; and in the field of drones, By using Quark electric drive technology, the carrying capacity and battery life can be greatly improved. Combined with AI technology, unmanned express delivery business is no longer a distant fantasy... The grand narrative with Tesla lacks details, Quark electric drive technology This real breakthrough is also a reflection of Aian's down-to-earth investment in technology. As Quark electric drive technology continues to evolve, it may be used in many high-precision fields such as intelligent robots, mechanical exoskeletons, medical care, and aerospace in the future to make high-performance machinery portable.
The resulting chain reaction may even rewrite the way the entire society operates, making the world of science fiction come true. On January 30 this year, Forbes China released the list of new unicorns in 2022, and Aian ranked first among the new unicorns in the world. This is the second time that Aian has been recognized by an international authoritative organization after being named an innovative enterprise super unicorn in 2022 and China's emerging TOP brand with the most growth potential in 2022. With scientific research results and technological innovation as its internal driving force, Aian has also sounded the clarion call for an IPO on the Science and Technology Innovation Board, and the future is promising.
