onsemi announced an expanded strategic collaboration with NIO to advance next-generation electric vehicle platforms. The partnership focuses on NIO’s transition from 400V to 900V architectures using onsemi’s EliteSiC enhanced M3e technology.
The collaboration builds on a longstanding partnership that previously supported NIO’s 400V platforms. It includes deeper engineering and system-level alignment for NIO’s latest EV lineup, with multiple models, including the flagship ES9 SUV, debuting at the 2026 Beijing Auto Show featuring onsemi technology.
onsemi’s EliteSiC enhanced M3e technology provides optimized switching performance through improved body diode characteristics. It reduces energy losses while maintaining short-circuit robustness, leading to higher system output, improved thermal performance, and increased drivetrain efficiency.
These improvements are intended to deliver longer driving range by reducing energy lost as heat, stronger and more consistent acceleration, shorter charging times, and reliable performance under demanding conditions.
“Electrification is entering a new phase where system efficiency and scalability are paramount,” said Hassane El-Khoury, President and CEO of onsemi. “Our expanded collaboration with NIO demonstrates how deep engineering alignment and aligned technology roadmaps can accelerate the transition to high-voltage architectures. With our EliteSiC technology, we are enabling higher performance, improved efficiency, and faster time-to-market for next-generation EV platforms.”
“NIO has consistently pushed the boundaries of intelligent electric mobility,” said Alan Zeng, CEO of XPT, NIO’s powertrain unit. “Our collaboration with onsemi has evolved alongside our technology roadmap from early 400V systems to today’s 900V platforms. The performance and reliability of onsemi’s EliteSiC technology, combined with strong technical collaboration, are helping us deliver more efficient, high-performance vehicles to our customers worldwide.”
