onsemi and Geely Auto Group have announced an expansion of their global strategic collaboration, aimed at accelerating the development of next-generation electric and hybrid vehicles. The collaboration focuses on deeper system-level integration of onsemi’s silicon carbide (SiC) technologies across Geely’s vehicle platforms to enable faster, more efficient EV performance.
EliteSiC Integrated into Geely’s SEA-S–based SEP System
As part of this development, Geely is highlighting its SEA-S-based Super Electric Power (SEP) system, which incorporates onsemi’s EliteSiC solutions within its electric drive architecture. These advanced systems are designed to leverage high-voltage platforms, supporting quicker acceleration, longer driving range, and reduced charging times.
By increasing power density, onsemi’s SiC technology enables compact and lightweight system design without compromising performance. This contributes to improved vehicle dynamics and better utilization of interior space. In addition, enhanced thermal management ensures stable output under demanding conditions, supporting durability and consistent performance over time. Together, these improvements deliver a smoother and more responsive driving experience, with faster acceleration, efficient power delivery, and reduced charging downtime.
Why 900V Architectures Matter for the Future of EVs
At a fundamental level, moving to a 900V vehicle architecture is about improving how efficiently electricity flows through the system. Higher voltage allows automakers to deliver greater power while minimizing heat generation and energy losses. For drivers, this results in tangible benefits such as quicker charging, extended range, and more consistent performance. Technologies like onsemi’s EliteSiC are designed to support these high-voltage systems, offering improved efficiency and reliability, and helping advance electric vehicles toward better speed, convenience, and overall driving experience.
Shaping the Next Phase of EV Platform Design
“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, President and CEO, onsemi
“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, CEO, Geely Auto Group
Delivering Tangible Benefits for Drivers
The expanded collaboration directly translates into meaningful, real-world benefits for drivers:
- Longer driving range through reduced energy losses
- Faster charging times enabled by high-voltage architectures
- Stronger acceleration and performance from higher power density
- Greater reliability and durability through improved thermal management
- A smoother driving experience from more efficient power delivery
As electric vehicle platforms become increasingly complex, automakers are placing more importance on early system-level design choices that shape efficiency, reliability, scalability, and long-term performance. The expanded partnership between onsemi and Geely Auto Group reflects this shift, highlighting the growing role of semiconductor innovation in vehicle development. By integrating advanced technologies at the design stage, the collaboration supports the creation of next-generation electric vehicles that balance performance, efficiency, and everyday usability.
