Onsemi and Geely Expand Collaboration to Support Next-Gen 900V EV Architectures

Why It Matters

The alliance accelerates the rollout of high‑voltage EV platforms, giving both companies a competitive edge as the market demands faster charging and greater efficiency. It also illustrates how deep system‑level partnerships are becoming essential for meeting future electrification targets.

Key Takeaways

• onsemi’s EliteSiC enables 900 V EV architectures
• Geely integrates EliteSiC into its SEA‑S SEP system
• Higher voltage reduces heat loss, speeds charging
• Lighter power modules free interior space and improve dynamics
• Collaboration pushes EV performance and reliability forward

Pulse Analysis

The automotive industry is rapidly converging on 900‑volt architectures as a means to overcome the energy‑loss constraints of traditional 400‑volt systems. Higher voltage allows more power to flow with less current, cutting heat generation and enabling smaller, lighter components. Silicon‑carbide (SiC) semiconductors, such as onsemi’s EliteSiC, excel in these conditions, offering superior efficiency, faster switching speeds, and robust thermal performance that conventional silicon cannot match. This technology shift is a cornerstone of the next wave of electric vehicle design.

Onsemi’s expanded partnership with Geely illustrates how automakers are moving semiconductor selection earlier in the vehicle development cycle. By embedding EliteSiC at the system level of Geely’s SEA‑S‑based Super Electric Power platform, the two firms can co‑optimize hardware and software, reducing integration risk and shortening time‑to‑market. The result is a powertrain that delivers quicker acceleration, extended range, and markedly shorter charging sessions—all while freeing up cabin space thanks to lighter, more compact modules. Such deep collaboration also secures supply chain stability for onsemi and positions Geely as a technology‑forward brand in the fiercely competitive Chinese EV market.

The broader implications extend beyond the two companies. As more manufacturers adopt 900‑volt platforms, the demand for SiC components will surge, prompting intensified competition among semiconductor suppliers and potentially driving down costs. Consumers stand to benefit from faster home and public charging, longer trips between charges, and vehicles that feel more responsive. For investors and industry analysts, the onsemi‑Geely deal serves as a bellwether for the accelerating convergence of power electronics and vehicle architecture, a trend that will shape EV performance standards for the next decade.
