onsemi Expands Collaboration with NIO for 900V EV Platforms Using EliteSiC M3e
onsemi is extending its multi-year partnership with NIO to support the automaker's shift from 400V to 900V EV architectures using its EliteSiC enhanced M3e technology. These modules reduce energy losses, boost drivetrain efficiency and enable faster charging and longer range on the ES9 debuting at the 2026 Beijing Auto Show.
1. Collaboration Expansion
onsemi is deepening its strategic partnership with NIO by transitioning support from 400V to next-generation 900V electric vehicle architectures. This extension leverages a multi-year relationship to accelerate integration of onsemi’s EliteSiC enhanced M3e technology into NIO’s powertrain systems.
2. Technical Advancements
EliteSiC enhanced M3e modules optimize switching performance by improving body diode characteristics and reducing energy losses (Eon), while maintaining short-circuit robustness. These refinements translate to higher system output, improved thermal performance and increased overall drivetrain efficiency.
3. Model Integration and Debut
The upgraded silicon carbide modules will underpin flagship models such as the ES9 and additional vehicles slated to appear at the 2026 Beijing Auto Show. NIO’s latest lineup will showcase the high-voltage, fast-charging capabilities enabled by onsemi’s technology.
4. Strategic Industry Impact
The collaboration illustrates a broader trend of tighter alignment between automakers and semiconductor suppliers as EV platforms demand higher power densities. onsemi’s system-level approach aims to reduce development complexity and accelerate time-to-market for scalable, high-performance EV architectures.
