On March 3rd, Ai 'an released a new generation of high-performance integrated electric drive technology group-Quark electric drive, which can generate powerful power with a very small volume, and the power density of the motor is as high as 12kw/kg, which is 1% higher than the industry's 6kw/kg. A palm-sized motor can bring super horsepower beyond the V8 engine! Achieving this breakthrough is no less than the chip industry's fast-forward from the "28 nm" era to the "3 nm" era.
Coincidentally, Tesla investors announced its new generation of self-developed electric drive system, which will further reduce the cost by reducing the use of silicon carbide and other materials. On the one hand, the pursuit of ultimate cost control, on the other hand, the pursuit of ultimate performance transcendence, the two sides seem to have formed two sets of logical and technological development routes.
After picking up the unfinished fruit of Tesla, Aeon broke through the world-class problem of electric drive
From ordinary applications such as balance cars and unmanned aerial vehicles, to high-tech fields such as "the country's heavy weapon" aircraft carrier and space exploration, motors play an indispensable role, 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 constantly pursuing the ultimate power density.
in fact, the breakthrough of motor power density has always been a world-class problem. Numerous engineers and scientific research institutions are committed to improving its power density. There are successes and failures. The breakthrough of power density faces two world problems.
on the one hand, we should consider how to achieve greater power output under the condition of constant volume. This requires that we must explore the space limit of the motor, so that every point of the motor can release the maximum potential. At the same time, the power can be increased by increasing the voltage. However, every voltage increase of 1V is a huge system-level project involving materials, technology, software, packaging and safety.
on the other hand, we should also avoid high power output loss, and try our best to avoid wasting the hard-won power on the useless work of generating heat.
in the ten years of rapid development of new energy automobile industry, the motor power density of the industry has increased from 2kw/kg to 6kw/kg. With the emergence of the quark electric drive technology, the power density of the motor was increased to 12kw/kg by leaps and bounds, and the unfinished fruit of Tesla was picked.
Three pioneering technologies lead to the change of driving mode
The R&D team of E 'an electric drive 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 heating loss", we continue to carry out technical iterative development, thus accumulating a series of innovative technologies such as nanocrystalline-amorphous super-efficiency motor, X-PIN flat wire winding, 9V high-efficiency silicon carbide, E-drive software, and electronic gear shifting without power interruption. Among them, the core is three forward-looking technologies:
The world's first "nanocrystalline-amorphous" super-efficiency motor
Since the development of permanent magnet synchronous motor technology, the loss of motor core is the main factor affecting the working efficiency of the motor. Based on the innovative development of basic raw materials and electromagnetic principles, the team of Ai 'an Electric Machinery has designed a "nanocrystalline-amorphous" alloy material and its batch preparation process. Compared with the traditional smelting process of iron-based silicon steel materials, the cooling rate of nanocrystalline-amorphous materials is as high as 1 million ℃/s, which is 1 times faster than that of 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. Aeon innovatively applied this material to make motor iron core, reducing the motor iron core loss by 5%, thus effectively reducing the motor energy loss, improving the motor working condition efficiency to 97.5% and the motor maximum efficiency to 98.5%.
the industry's first X-PIN flat wire winding
Aeon combines the patented X-PIN flat wire stator technology and carbon fiber high-speed rotor technology, and the electric drive power is increased by more than 3% under the condition of reducing the volume by 25%. Based on the progress of motor technology, the future products will be miniaturized, lightweight and diversified. X-PIN carbon fiber high-speed motor technology has three national patents with unique platform winding scheme, which can realize multi-platform compatibility in the power range of 7kW~32kW and the torque range of 22~45Nm.
the world's highest 9V silicon carbide power module
ean is deeply involved in the construction of the SiC industrial chain and has developed its own packaging design. Breakthroughs were made in four directions: chip layout, current sharing consistency, reducing chip switching delay and designing laminated power circuit. At the same time, combined with the innovation of all-silver precision low-temperature sintering process, the circuit inductance of SiC module was reduced by more than 5%, the thermal resistance was reduced by about 25%, the chip current capacity was improved by more than 1% and the power cycle life was improved by about 1%.
with the safe and reliable driving and protection design of SiC chip, the characteristics of high withstand voltage, high power density and high efficiency of silicon carbide are brought into full play, which helps quark electric drive to achieve the highest full-power working voltage of 9V, the peak power of over 32kw and the highest efficiency of over 99.8%, ranking the top level in the industry.
a series of technical innovations of quark electric drive all start from details and constantly strive for perfection, thus breaking through the contradiction of "big power and small size", and also endowing Ai 'an Hyper SSR and Hyper GT with inherent extreme performance and extreme space experience! Let Ai 'an Hyper SSR achieve the world's fastest multi-motor acceleration of 1.9 seconds and Hyper GT achieve the world's fastest single motor acceleration of 4.9 seconds and 1 kilometers.
Open up the future and imagine that everyone is Iron Man.
This quark electric drive broke through the contradiction of "big power and small size" for the first time, which made the research and development of electric drive in Ai 'an enter the "nano era" and set a new milestone for the research and development history of electric drive technology in Ai 'an, which is also the epitome of the rapid development of new energy automobile industry in China.
As the first EV+ICV full-stack self-developed automobile enterprise in China, Aeon has achieved many technological breakthroughs. Not only have we independently developed three original battery technologies, namely, magazine battery, super-double-speed battery and sponge silicon battery, which have solved the pain points of three industries in one fell swoop, but we have also introduced a new generation of high-end technologies such as AEP3. platform and Spirit architecture.
Four years ago, Ai 'an and Tesla were the only car companies with pure electric platforms. Last year, Ai 'an released a new generation platform AEP 3., and this investor day, the new generation platform promised by Tesla jumped again. Although Musk released the third chapter of the secret grand plan, the stock price fell all the way during the event. The reason is that Tesla's ideal is grand but the details are insufficient, and he just draws cakes, but he doesn't use enough new technology to support it.
On the basis of self-research in the whole stack, Ai 'an also established Ruipai Power Technology Co., Ltd., focusing on forward-looking power technology R&D and industrialization, and comprehensively integrating R&D, intelligent manufacturing, sales and service, creating more and more extreme power technology products and leading the industry reform.
with the advent of quark electric drive, people have more imagination space for the future automobile form. Perhaps in the near future, lightweight and powerful hub motors can be mass-produced. At that time, side parking can be "overbearing and rampant" like crabs, and even narrow road sections can easily turn in the same place, and even accelerate the mass production of more car forms such as submarine cars and flying cars, bringing users a fantasy travel experience of "taking the moon for nine days and catching turtles in the next five oceans".
of course, quark electric drive is not limited to cars, but also can be used in many forward-looking fields to unlock more intelligent life scenes in the future. For example, in the field of medical science and technology, quark electric drive can be used to make dynamic prosthetic limbs, so that disabled people can also have the activity ability of normal people; Let wearable machines become a part of the human body, and everyone is Iron Man; For example, in the field of unmanned aerial vehicles, the carrying capacity and endurance can be greatly improved by using quark electric drive technology. Combined with AI technology, unmanned express delivery business is no longer an unreachable fantasy ... < P > The grand narrative with Tesla lacks details. The real breakthrough of quark electric drive technology is also the embodiment of Ai 'an's down-to-earth investment in technology. With the continuous evolution of quark electric drive technology, it may be applied to intelligent robots, mechanical exoskeletons, medical care, aerospace and other high-precision fields in the future, making high-performance machinery portable. The resulting chain reaction may even rewrite the operation mode of the whole society and make the science fiction world shine into reality.
On January 3th this year, Forbes China released the list of new unicorns in 222, and Ai 'an ranked first among the new unicorns in the world. This is the second time that Ai 'an has been recognized by international authorities after being rated as an innovative enterprise super unicorn in 222 and a TOP brand with the most growth potential in China in 222. With scientific research achievements and technological innovation as the internal driving force, Ai 'an has also sounded the horn of science and technology innovation board IPO, and the future can be expected.
