Geely picks onsemi EliteSiC for next-gen 900V EVs

Geely Auto Group and US semiconductor maker onsemi have expanded their strategic partnership to embed onsemi’s EliteSiC silicon carbide (SiC) power technology across Geely electric vehicle platforms. The deal centres on the SEA-S architecture, the Super Hybrid variant of Geely’s Sustainable Experience Architecture, supporting a move to 900V electrical systems.

Geely is showcasing its SEA-S-based Super Electric Power (SEP) system at the heart of the collaboration, with EliteSiC chips embedded in the electric drive. onsemi and Geely say the higher-voltage architecture supports faster charging, longer range, stronger acceleration and steadier performance under load.

Higher voltage moves more power with less heat and energy loss but requires components rated for harsher operating conditions. EliteSiC parts are designed for those voltages and thermal stresses, which onsemi says lets OEMs pack more performance into smaller inverters and converters.

The deal extends earlier work between the two companies into system-level co-design, bringing semiconductor choice into platform decisions earlier in the cycle. Both firms framed that as the new normal for high-voltage EV programmes.

Geely Auto Group Chief Executive Gan Jiayue called onsemi a key system-level partner. onsemi President and Chief Executive Hassane El-Khoury said the EV market was entering a new phase driven by higher-voltage architectures. Neither firm gave a launch date for SEA-S vehicles using the EliteSiC stack.
