Ideal prospect of automotive SiC power chip drive motor controller

In today's rapidly developing electric vehicle industry, the drive motor controller as one of the core components of electric vehicles, its performance advantages directly affect the vehicle's power system and endurance performance. Ideal Car, a pioneer in the research and development of intelligent electric vehicles, has increased its investment and research in electric drive systems in recent years. Among them, the development of motor controllers using silicon carbide (SiC) power chips has become one of its important strategies. Compared with traditional silicon materials, SiC materials have better conductivity, higher temperature resistance and stronger pressure resistance, which provides a solid foundation for the research of high efficiency of electric vehicles.

Advantages of SiC power chips

The main advantages of SiC power chips are high temperature, high pressure, high frequency and power density. First, SiC materials can withstand higher operating temperatures, usually up to 300 ° C, while the operating temperature of traditional silicon materials is generally around 150 ° C. This high temperature characteristic allows the motor controller to operate in a more efficient state, reducing energy loss due to heating. In addition, SiC's high electrical conductivity and voltage resistance give it significant advantages in high-power

applications, greatly improving the power conversion efficiency of electric vehicles.

Second, SiC chips enable more efficient power conversion at high frequencies. By increasing the switching frequency, the volume of the motor controller can be effectively reduced, which will directly affect the lightweight design of the vehicle and improve the flexibility and endurance of the vehicle. Finally, the packaging technology of SiC power chip is relatively mature, which can achieve good heat dissipation effect and extend the service life and stability of the device.

Drive motor controller development technical route

Ideal Automobile has carried out a series of technical route planning in the development of SiC power chip drive motor controller. First, the independent research and development of core technology is a major strategy of ideal automobile, and it is planned to build a SiC power chip with completely independent intellectual property rights. This will give the ideal car a stronger competitive advantage in the field of electric drive technology.

Secondly, the focus will be on system integration technology to improve the accuracy of current and voltage regulation by optimizing the design of motor controllers to achieve more efficient power control. At the same time, the ideal car will also explore the control algorithm based on SiC, improve the overall performance of the motor controller through intelligent means, so that it has stronger adaptability and reliability in the new energy market.

In terms of material selection, ideal automobile will also examine the diversity of SiC materials, explore the combination of silicon carbide and BZX84B7V5GS08 chip manufacturing process, and strive to achieve efficient and low-cost power chip production. In addition, Ideal Automobile will continue to establish cooperative relations with scientific research institutions and material manufacturers at home and abroad, and introduce the most cutting-edge technologies and concepts to promote the rapid mass production and application of SiC power chips.

Market prospect and competition pattern

As the global demand for electric vehicles continues to rise, major car companies have accelerated the layout of the new energy vehicle market. According to the market research report, the electric vehicle market is expected to grow at an annual rate of more than 20% in the next few years. In this environment, the research and development and application of SiC power chips in ideal cars can not only enhance their own market competitiveness, but also is expected to inject new vitality into the entire electric vehicle industry chain.

In the competitive landscape, although there are many car companies and technology companies potential market, but the ideal car with its accumulation of electric drive system technology and research and development investment in the field of SiC materials, formed a certain barrier. At the same time, with the progress of technology, the cost of SiC power chips is expected to gradually decline, which will reduce the overall cost of electric vehicles, providing help for the market share of ideal cars.

Continuous innovation and ecological cooperation

Ideal Automobile knows that in the era of rapid technological change, only continuous innovation can ensure the leading position of products. Therefore, in the research and development process of SiC power chip drive motor controller, Ideal automobile will pay attention to cross-border cooperation and ecological construction, forming a multi-party collaborative innovation chain.

By actively establishing industry-university-research cooperation with universities and research institutions, ideal automobile can obtain support in many aspects such as cutting-edge technology, talent training and knowledge sharing. At the same time, in the production process, Ideal Automobile will also seek cooperation with advanced manufacturing and equipment manufacturers to improve the production process and efficiency, to achieve breakthroughs in the continuous innovation of SiC power chips.

In terms of supporting facilities, Ideal Automobile is planning to establish a complete set of electric vehicle powertrain test laboratories and inspection facilities. Through these advanced experimental conditions, the ideal car can evaluate the actual performance of the SiC power chip in time before practical application, ensuring its safety and reliability under a variety of working conditions.

Long-term development path

The research and development of SiC power chip drive motor controller is not only an improvement of existing technology, but also a big step towards the future development direction of intelligent electric vehicles. The Ideal Car plans to iteratively update its drive system to achieve more efficient power output, longer driving range and a superior user experience. At the same time, Ideal Automobile will be committed to promoting industry standardization, advocating the industry development concept of independent innovation and technology sharing, in order to jointly promote the sustainable development of the new energy automobile industry.
