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 is an increase of 100. A palm-sized motor can bring huge horsepower beyond the V8 engine!
From common civilian applications such as balance cars and drones that are common in daily life, 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.
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. But every 1V increase in voltage is a huge system-level project involving materials, processes, software, packaging, and safety;
The Aian Motor team innovatively developed from basic raw materials and electromagnetic principles, and designed a " Nanocrystalline-amorphous "alloy materials and batch preparation process; compared with the traditional smelting process of iron-based silicon steel materials, the cooling speed of nanocrystalline-amorphous materials is as high as 1 million ℃/s, which is 1000 times faster than iron-based silicon steel materials; with 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.
Aion 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%. 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.
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, SiC module circuit noise is reduced More than 50%, the thermal resistance is reduced by 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 perfection, thereby breaking through the incompatible contradiction of "large power and small size", and also endows Aian'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.
As the first car company in China 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.
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.
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...
