Recruit engine process engineer

On March 3rd, Aian released a new generation of high-performance integrated electric drive technology group-Quark electric drive, which can generate powerful power in a very small volume, and the power density of the motor is as high as 12kw/kg, which is 100% 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 fast forward of the chip industry from the "28 nm" era to the "3 nm" era.

Taking off Tesla's unfinished fruit, Ian broke through the world-class problem of electric drive.

In fact, the breakthrough of motor power density has always been a world-class problem. Many 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. On the other hand, to avoid the loss of high power output, the final increased power should be avoided as much as possible and wasted on the useless work of generating heat.

In the 10 year when the new energy automobile industry developed rapidly, the power density of motor in the industry increased from 2kw/kg to 6kw/kg. With the emergence of quark electric drive technology, the power density of the motor has increased by leaps and bounds to 12kw/kg, and the unfinished fruit of Tesla has been picked.

Three groundbreaking technologies, leading the change of driving style

Ai 'an 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 heating loss", we have continued to carry out technical iterative development, thus accumulating a series of innovative technologies such as nanocrystalline-amorphous ultra-efficient motor, X-PIN flat wire winding, 900V 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" ultra-efficient motor

Since the development of permanent magnet synchronous motor technology, the iron loss of the motor is the main factor affecting the efficiency of the motor. Based on the innovative development of basic raw materials and electromagnetic principles, the team of Ai 'an Electric Machinery designed "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 10,000 ℃/s, which is 1 10,000 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, which reduced the loss of motor iron core by 50%, thus effectively reducing the energy loss of motor, improving the working efficiency of motor to 97.5% and the maximum efficiency of motor to 98.5%.

Industry's first X-lead flat wire winding

Using the patented X-PIN flat wire stator technology and carbon fiber high-speed rotor technology, the electric drive power is increased by more than 30% while the volume is reduced by 25%. Based on the progress of motor technology, future products will be miniaturized, lightweight and diversified. X-PIN carbon fiber high-speed motor technology has three national patents and a unique platform winding scheme, which can realize 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 SiC industrial chain and independently develops packaging design. Breakthroughs have been made in four directions: chip layout, current sharing consistency, reducing chip switching delay and design of laminated power supply circuit. At the same time, combined with the innovation of all-silver precision low-temperature sintering process, the circuit inductance of SiC module is reduced by more than 50%, the thermal resistance is reduced by about 25%, the chip current capacity is increased by more than 10%, and the power cycle life is increased by about 100%.

Combined 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 SiC are fully exerted, which helps quark electric drive to achieve the highest full-power working voltage of 900V, with the peak power exceeding 320kw and the highest efficiency exceeding 99.8%, ranking the top level in the industry.

A series of technological innovations of quark electric drive are based on details and constantly strive for the ultimate, thus breaking through the contradiction of "large power and small size" and giving Aian Hyper SSR and Hyper GT the inherent ultimate performance and ultimate space experience! Let Aian Hyper SSR achieve the world's fastest multi-motor acceleration 1.9 seconds, and Hyper GT achieve the world's fastest single motor acceleration of 4.9 seconds and 100 kilometers.

Open the future and imagine that quark electric drive will turn everyone into Iron Man.

Quark electric drive broke through the contradiction of "large power and small size" for the first time, which made the research and development of Ai 'an electric drive enter the "nano age", set a new milestone for the research and development history of Ai 'an electric drive technology, and also epitomized the rapid development of China's new energy automobile industry.

As the first EV+ICV independent research and development vehicle enterprise in China, AEON has achieved a number of technological breakthroughs. Not only independently developed three original battery technologies, namely magazine battery, super-fast battery and sponge silicon battery, but also solved the pain points of the three major industries in one fell swoop, and introduced a new generation of high-end technologies such as AEP3.0 platform and Spirit architecture.

Four years ago, Aian and Tesla were the only car companies with pure electric platforms. Last year, Aian released a new generation platform AEP 3.0, and this year's investor day, Tesla promised a new generation platform to jump again. Although Musk released the third chapter of the secret grand plan, the share price fell all the way during the event. The reason is that Tesla's ideal is grand but the details are insufficient, and it is just drawing cakes, but it is not supported by enough new technologies.

On the basis of full-stack self-research, Ai 'an also established Ruipai Power Technology Co., Ltd., focusing on forward-looking power technology research and development and industrialization, fully integrating R&D, intellectual manufacturing, sales and service, creating more and more extreme power technology products and leading industry changes.

With the appearance of quark electric drive, people have more imagination space for the future car form. Perhaps in the near future, light-weight and high-power hub motors can be mass-produced. By then, side parking can be "overbearing and rampant" like a crab, 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 fantastic travel experience of "taking the moon in nine days and catching turtles in 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 prostheses, so that disabled people can also have the activity ability of normal people; Let the wearable machine become a part of the human body, 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 artificial intelligence technology, unmanned express service is no longer an unreachable fantasy. ...

The grand narrative with Tesla lacks details, and 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. With scientific research achievements and technological innovation as the internal driving force, Ai 'an also sounded the horn of IPO of science and technology innovation board, and the future can be expected.
