On March 3, Aion released a new generation of high-performance integrated electric drive technology group - Quark electric drive, which can burst out powerful power in a very small size, with a motor power density as high as 12kw/kg. Compared with the industry’s 6kw/kg, it has increased by 100%. 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.
Aian breaks through the world-class problem of electric drive
From common civilian applications such as balancing cars and drones, to "national treasures" aircraft carriers and space exploration. Motors play an indispensable role in high-end and sophisticated fields such as motors, 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.
The breakthrough in motor power density has always been a world-class problem, mainly facing two major 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 must 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 Aianquark electric drive technology has greatly increased the motor power density to 12kw/kg, which is eye-catching.
Three pioneering technologies
Aion’s 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 which are three forward-looking technologies:
The world's first "nanocrystalline-amorphous" super-efficiency motor
With the development of permanent magnet synchronous motor technology, the motor core loss is The main factors affecting the operating 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 applies this material to make motor cores, reducing motor core losses by 50%, thereby effectively reducing motor energy losses and increasing motor operating efficiency to 97.5%. The maximum efficiency reaches 98.5%.
The industry's first X-PIN flat wire winding
Aion combines its own patented X-PIN flat wire stator technology and carbon fiber high-speed rotor technology to reduce the volume by 25%. The electric drive power is increased by more than 30%. 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
Aion is deeply involved in the construction of the SiC industry chain and develops its own packaging design. Breakthroughs are made from four directions: chip layout, current sharing consistency, reduction of chip switching delay, and stacked power circuit design. At the same time, combined with the innovation of all-silver precise low-temperature sintering process, the SiC module circuit noise is reduced by more than 50% and the thermal resistance is reduced. About 25%, the chip flow capacity is increased by more than 10%, and the power cycle life is increased by about 100%.
Combining safe and reliable SiC chip drive and protection design, giving full play to the high withstand voltage, high power density, and high efficiency characteristics of silicon carbide, helping the Quark electric drive achieve the highest full power operating voltage of 900V, and the peak power is as high as More than 320kw, the maximum efficiency exceeds 99.8%, ranking at the top level in the industry.
A series of technological innovations of the Quark electric drive start from the details and continue to achieve the ultimate, thus breaking through the incompatible contradiction of "large power and small size", and also empowering Aion's Hyper SSR And the ultimate performance and ultimate space experience inherent in Hyper GT! 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.
The future becomes reality
This time, the Quark electric drive breaks through the contradiction of "large power and small size" for the first time, bringing Aian's electric drive research and development into the "nano era" , setting a new milestone in the history of Aion's electric drive technology research and development, which is also the epitome of the take-off of China's new energy vehicle industry.
As the first car company in China to develop its own full-stack EV+ICV, Aion 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.
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, and comprehensively integrating R&D, intelligent manufacturing, sales and service. , create more and more extreme power technology products and 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...
Quark electric drive technology is actually implemented this time Breakthroughs are 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.
