Recently, STMicroelectronics (ST) signed a long-term silicon carbide (SiC) supply agreement with Li Auto, a leading Chinese new energy vehicle manufacturer, aiming to support Li Auto’s strategic plan to enter the high-voltage pure electric vehicle market. This cooperation will provide Li Auto’s pure electric models with excellent performance and stability, helping it stand out in the competition in the electric vehicle market.
As the electrification and green and low-carbon transformation of the automotive industry continue to deepen, high-voltage pure electric vehicles are becoming more and more popular due to their high energy efficiency and long cruising range. As a leader in the field of new energy vehicles, Li Auto has launched its first home technology pure electric flagship MPV, and plans to launch more high-voltage pure electric models in the future. In order to ensure the excellent performance of the new model, Li Auto chose to use a large number of STMicroelectronics' silicon carbide MOSFETs in the electric drive inverter.
STMicroelectronics' silicon carbide has higher switching frequency, breakdown voltage and thermal resistance, which can significantly improve the performance and energy efficiency of power transistors, especially in the environment of high-voltage pure electric vehicles. Li Auto's upcoming 800V high-voltage pure electric platform will use STMicroelectronics' third-generation 1200V SiC MOSFET advanced technology, which has industry-leading process stability, performance, energy efficiency and reliability.
Meng Qingpeng, vice president of supply chain of Li Auto, said: "Li Auto is committed to providing family users with luxury electric vehicles that exceed expectations. The signing of the SiC supply agreement with ST confirms Li Auto's firm decision to develop pure electric vehicle products. We are optimistic about Future cooperation with ST, the global leader in silicon carbide technology, will surely be an innovative and successful partnership."
STMicroelectronics' share of the global SiC MOSFET market exceeds 50%, and its excellent performance in electric vehicles has won high praise from leading automotive OEMs. In the field of new energy vehicles, STMicroelectronics’ silicon carbide has been widely used in vehicle charging and power modules.
Cao Zhiping, executive vice president of STMicroelectronics and president of China, said: "STMicroelectronics is a global leader in power semiconductors and wide bandgap technology, and is also a long-term supplier to many well-known automobile manufacturers and first-tier suppliers. We The silicon carbide supply agreement signed with Li Auto marks another important step based on the long-term cooperation between the two parties in other automotive applications. ST is committed to supporting Li Auto to become the leading brand of high-end new energy vehicles in China and providing users with our SiC innovative technology Delivering superior vehicle performance and range.”
The signing of this long-term supply agreement will bring deeper cooperation between STMicroelectronics and Li Auto and help Li Auto achieve greater success in the competition in the high-voltage pure electric vehicle market. STMicroelectronics will continue to support Li Auto’s development of new energy vehicles and provide it with the most advanced silicon carbide technology and solutions. At the same time, STMicroelectronics will continue to increase its investment in the field of new energy vehicles and is committed to providing higher-performance, higher-efficiency power semiconductor products for the global automotive industry to help the automotive industry develop in a green and low-carbon direction.
With the continuous advancement and application of silicon carbide technology, the field of new energy vehicles will usher in more innovations and breakthroughs. STMicroelectronics will continue to work closely with its partners to jointly promote the development of new energy vehicle technology and provide better automotive products and services to global users.
