According to official news from Great Wall Motors, the company’s Innosilicon and STMicroelectronics recently signed a strategic cooperation agreement in Shenzhen to stabilize the supply of SiC chips.
According to reports, new energy vehicles are gradually advancing from 400V to 800V high-voltage platforms to meet the market needs of consumers for daily travel and long-distance travel. SiC chips (silicon carbide) are widely used in key applications such as electric drive inverters, electric vehicle on-board charging (OBC) and DC-DC converters (DC-DC) due to their excellent characteristics such as high voltage resistance and high junction temperature applications. in parts.
Great Wall Motors said that the signing of a strategic cooperation agreement with STMicroelectronics on the SiC chip business will further promote Great Wall Motors’ vertical integration and increase its efforts in new energy development.
Iit noted that STMicroelectronics also signed a long-term silicon carbide (SiC) supply agreement with Li Auto in December last year. According to the agreement, STMicroelectronics will provide silicon carbide MOSFETs to Li Auto to support Li Auto’s strategic plan to enter the high-voltage pure electric vehicle market.
The 800V high-voltage pure electric platform launched by Li Auto uses STMicroelectronics’ third-generation 1200V SiC MOSFET technology in the electric drive inverter.
