SCOTTSDALE, Ariz., April 27, 2026 (GLOBE NEWSWIRE) -- onsemi (Nasdaq: ON) today announced an expanded strategic collaboration with NIO Inc. (NYSE: NIO) to advance next-generation electric vehicle (EV) platforms. Building on a multi-year partnership, the companies are more closely engaging to accelerate NIO’s transition from 400V to 900V architectures, enabled by onsemi’s latest EliteSiC enhanced M3e technology.
Delivering Real-World Gains in Range, Charging and Performance
onsemi’s EliteSiC enhanced M3e technology delivers optimized switching performance through improved body diode characteristics, reducing energy losses (Eon) while maintaining strong short-circuit robustness. These advances translate into higher system output, improved thermal performance, and increased overall drivetrain efficiency. For drivers, this means:
- More miles from every charge, by reducing energy lost as heat in the powertrain
- Stronger, more consistent acceleration, including at highway speeds and under load
- Shorter charging times, supported by high-voltage, fast-charging systems
- Reliable performance over time, with power systems designed to operate under demanding conditions
Longstanding Partnership Evolves from 400V to Next-Generation Platforms
The expanded collaboration builds on a longstanding partnership, which began with onsemi’s EliteSiC technology supporting NIO’s 400V platforms and has evolved into a strategic, system-level alignment. Today, onsemi’s EliteSiC technology underpins NIO’s transition to 900V architectures, including its latest flagship SUV, the ES9, and additional models debuting at the 2026 Beijing Auto Show.
