Onsemi, a leading company in intelligent power and sensing technology, said it is expanding its strategic collaboration with NIO Inc to accelerate development of next-generation EV platforms. Building on a partnership that has continued for years, the two companies will speed NIO's transition to a 400V–900V architecture through onsemi's latest EliteSiC enhanced M3e technology.
Onsemi's EliteSiC enhanced M3e technology improves switching performance through improved body diode characteristics, reduces energy loss (Eon), and maintains robust short-circuit durability. These technological advances lead to higher system output, improved thermal performance, and increased overall drivetrain efficiency. This provides drivers with benefits such as energy savings, stable acceleration performance, and shorter charging times.
The expansion of this collaboration builds on a long-standing partnership that began with onsemi's EliteSiC technology supporting NIO's 400V platform and has now developed into a strategic, system-level collaboration. Onsemi's EliteSiC technology currently underpins NIO's transition to a 900V architecture and is applied to NIO's latest flagship SUV, the ES9, and additional models unveiled at the Beijing Auto Show in 2026.
Hassane El-Khoury, onsemi CEO, said, "Electrification is entering a new phase where system efficiency and scalability are key. The expanded collaboration with NIO shows how close engineering cooperation and a consistent technology roadmap can accelerate the transition to high-voltage architectures. Through our EliteSiC technology, we are helping boost performance, improve efficiency, and shorten time to market for next-generation EV platforms."
Allan Zeng, CEO of NIO's powertrain division XPT, said, "NIO has continually pushed the limits of intelligent electric mobility. Our collaboration with onsemi has evolved alongside our technology roadmap, from early 400V systems to today's 900V platforms. Based on the performance and reliability provided by onsemi's EliteSiC technology and our close technical cooperation, we are helping deliver high-performance, high-efficiency vehicles to customers worldwide."
The collaboration between the two companies reflects a broader trend in the auto industry in which close cooperation between automakers and semiconductor corporations is becoming increasingly important as vehicle power consumption rises. By supporting system-level integration, onsemi helps customers bring scalable, high-performance EV platforms to market quickly and efficiently, reducing development complexity and increasing execution speed. This approach is becoming more important as automakers transition to high-voltage architectures and advanced electric drive systems.
