onsemi and Geely expand collaboration to support next-gen 900V EV architectures
Intelligent power and sensing technology firm onsemi of Scottsdale, AZ, USA and China-based Geely Auto Group Co Ltd have expanded their global strategic collaboration aimed at accelerating the development of next-generation electric and hybrid vehicles. The partnership deepens system-level integration of onsemi’s EliteSiC silicon carbide technologies across Geely’s vehicle platforms to drive faster, more efficient EV development.
EliteSiC integrated into Geely’s SEA-S-based SEP System
As part of the announcement, Geely is showcasing its SEA-S-based Super Electric Power (SEP) System — the Super Hybrid variant of Geely’s Sustainable Experience Architecture — which incorporates onsemi’s EliteSiC power technologies at the heart of its electric drive systems. These next-generation vehicles are designed to take full advantage of high-voltage 900V architectures, delivering faster acceleration, extended driving range, and significantly reduced charging times.
onsemi says that, by enabling higher power density, its technology allows more performance to be packed into a smaller, lighter system, contributing to improved vehicle dynamics and interior space. At the same time, enhanced thermal performance helps to maintain consistent output during demanding driving conditions while supporting long-term reliability. Drivers can hence benefit from quicker starts, smoother power delivery, and longer range with less time spent charging.
900V architectures for future EVs
At its core, the shift to 900V vehicle architecture is about moving electricity through the car more efficiently. By increasing voltage, automakers can deliver more power with less heat and energy loss, which translates directly into faster charging times, longer driving range, and stronger, more consistent performance. onsemi’s EliteSiC solutions enable this by handling higher voltages with greater efficiency and reliability.
Next phase of EV platform design
“The EV market is entering a new phase, driven by higher-voltage architectures and increasing system complexity,” says onsemi’s president & CEO Hassane El-Khoury. “Our expanded engagement with Geely reflects how automakers and semiconductor partners are working more closely and earlier to shape critical vehicle design decisions. Together, we are enabling EVs that deliver higher efficiency and performance,” he adds.
“As we advance our electrification strategy, closer coordination with technology partners is increasingly critical,” notes Geely Auto Group’s CEO Gan JiaYue. “Integrating onsemi technologies across our SEA-S-based electric vehicle platforms reflects this deeper collaboration in action. Working with onsemi as a key system-level partner enables stronger alignment across platform design and engineering execution.”
