onsemi and Geely Auto Group are expanding their strategic collaboration to accelerate next-generation electric and hybrid vehicle development. The move centers on deeper integration of silicon carbide (SiC) technologies into future vehicle platforms.

For eeNews Europe readers, the announcement highlights how power semiconductor innovation is increasingly shaping EV architectures and system-level design decisions, particularly as the industry moves toward higher-voltage platforms.

Deeper SiC integration in EV platforms

At the core of the partnership is the integration of onsemi’s EliteSiC power technologies into vehicles built on Geely’s SEA-S (Sustainable Experience Architecture – Super Hybrid) platform. These systems are designed to support emerging 900V electrical architectures, enabling faster charging, longer range, and improved performance consistency. Geely is already showcasing its SEA-S–based Super Electric Power (SEP) system, where EliteSiC devices play a central role in the electric drive. Higher power density allows more compact and lighter designs, while improved thermal performance supports reliability under demanding conditions. The result is a more efficient drivetrain with smoother power delivery and enhanced driving dynamics.

Why 900V matters

The shift from today’s typical 400V–800V systems to 900V architectures reflects a broader push for efficiency. Higher voltage reduces current for the same power level, cutting losses and heat generation. This directly translates into shorter charging times and extended driving range — key metrics for EV adoption. onsemi’s SiC technology is critical here, as it can handle higher voltages with better efficiency than traditional silicon.

Industry collaboration intensifies

“The EV market is entering a new phase, driven by higher-voltage architectures and increasing system complexity. 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.” — Hassane El-Khoury

“As we advance our electrification strategy, closer coordination with technology partners is increasingly critical. 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, supporting our goal of delivering high-performance, efficient electric vehicles to customers worldwide.” — Gan JiaYue

The collaboration underscores a growing trend: semiconductor vendors are no longer just component suppliers but key contributors to EV platform architecture and performance.
