onsemi and Geely Auto Group Expand Strategic Power Electronics Collaboration

The automotive industry is shifting from a focus on battery size to a focus on power efficiency, and the expanded strategic collaboration between onsemi and Geely Auto Group establishes a new standard for this transition. By integrating advanced EliteSiC (silicon carbide) technology directly into Geely’s SEA-S–based Super Electric Power (SEP) systems, the partnership moves beyond standard component supply toward deep system-level engineering. This approach allows Geely to differentiate its fleet from competitors by mastering the 900V architecture, a high-voltage threshold that many current electric vehicles have yet to achieve.

The Engineering Advantage of 900V Architectures
The primary technical hurdle for modern EVs is the balance between power delivery and heat management. The shift to a 900V architecture is a definitive solution to this problem because it allows electricity to move through the vehicle with significantly lower energy loss. By utilizing onsemi’s EliteSiC solutions, Geely can handle higher voltages with greater thermal stability than traditional silicon-based systems. This results in a higher power density, meaning more performance is extracted from a smaller, lighter system. This efficiency allows for faster acceleration and consistent power output even under demanding driving conditions, providing a more responsive experience than vehicles utilizing standard 400V or 800V systems.

Solving the Challenges of Range and Charging Speed
For consumers, the most tangible differentiation provided by this technology lies in the reduction of "range anxiety" and "charging downtime." The efficiency of silicon carbide semiconductors minimizes energy waste, which directly extends the driving range on a single charge. Furthermore, the high-voltage capability enabled by the collaboration facilitates drastically reduced charging times. Because the 900V system can accept more power without generating excessive heat, it overcomes the bottleneck that slows down charging at high-speed stations. This makes the electric driving experience increasingly comparable to the convenience of traditional refueling.

A New Model for Semiconductor Collaboration
The evolution of the EV market now requires automakers to make critical design decisions much earlier in the development cycle. Rather than selecting chips for a finished car, Geely and onsemi are co-engineering the platform's core to ensure that the hardware and software are perfectly aligned. This early-stage integration ensures that the vehicle's thermal management, durability, and power delivery are optimized as a single unit. This level of coordination helps Geely deliver a more refined, reliable, and high-performance vehicle that meets the growing complexity of the global EV market while maintaining a competitive edge in efficiency and everyday usability.
