Geely signs long-term SiC supply agreement and establishes joint lab with STMicroelectronics

STMicroelectronics and Geely Auto Group have signed a long-term Silicon Carbide (SiC) supply agreement to accelerate their existing cooperation on SiC devices. Under the terms of this multi-year contract, ST will provide multiple Geely Auto brands with SiC power devices for mid-to-high-end battery electric vehicles (BEVs), boosting Geely Auto’s NEV transformation strategy with improved performance, faster charging speeds and extended driving range.

In addition, building on their longstanding cooperation across multiple automotive applications, Geely and ST have established a joint lab to exchange information and explore innovative solutions related to automotive Electronics/Electrical (E/E) architectures (i.e. in-vehicle infotainment, smart cockpit systems), advanced driver assistance (ADAS), and NEVs.

Geely Auto Group has adopted ST’s third-generation SiC MOSFET devices in electric traction inverters. The combination of advanced inverter design with high-efficiency power semiconductors, like SiC, is the key to superior electric vehicle performance.

Geely Auto sold a total of 1.68 million vehicles in 2023, with NEV sales reaching 480,000 units, accounting for 28% of the company’s total sales for the year. This NEV sales volume represents a year-over-year increase of 48%.

ST provides SiC devices for a wide range of EV applications including traction inverter, OBC (onboard charger), DC-DC converter, EV charging station and e-compressor application, significantly enhancing the performance, efficiency, and range of NEVs. In June 2023, ST and Sanan Optoelectronics, a market leader in compound semiconductors in China, announced the creation of a new 200mm SiC device manufacturing JV in Chongqing, China.
