onsemi and Geely Auto Group have expanded their strategic collaboration to accelerate next-generation electric vehicle development, with a focus on high-voltage architectures and system-level integration.
The partnership centers on deeper adoption of onsemi’s EliteSiC technology across Geely’s SEA-S (Sustainable Experience Architecture – Super Hybrid) platform. These silicon carbide solutions enable the transition to 900V EV architectures, delivering higher efficiency, improved power density, and enhanced thermal performance.
From a system perspective, the move to 900V platforms represents a significant step forward in EV design. Higher voltage allows more efficient power transfer with reduced losses, translating into faster charging times, extended driving range, and more consistent performance under demanding conditions. onsemi’s SiC devices play a key role by supporting high-voltage operation with improved efficiency and reliability.
The collaboration also reflects a broader industry shift toward earlier and deeper semiconductor involvement in vehicle design. By working at the platform level, onsemi and Geely can optimize system architecture, accelerating development cycles and improving overall vehicle performance.
Strategically, this partnership strengthens onsemi’s position in the fast-growing SiC automotive market, while enabling Geely to enhance competitiveness in next-generation EV platforms. The integration of EliteSiC into Geely’s electric drive systems supports key performance improvements, including higher acceleration, reduced charging time, and better energy efficiency.
From a market standpoint, the announcement highlights the accelerating transition toward 800V–1000V EV architectures, a critical trend as automakers seek to meet increasing performance expectations and charging infrastructure demands. It also underscores the growing importance of close collaboration between semiconductor suppliers and OEMs in shaping future vehicle platforms.
