NIO ET9 full-domain 900V architecture
A high-voltage vehicle platform combining its powertrain, energy systems and fast-charging hardware
Data snapshot: October 13, 2026. Independent research; not a manufacturer website or buying advice.
How it works
At its December 2023 unveiling, NIO described ET9’s 900V-class architecture and advertised up to 600 kW peak charging capacity with matching hardware. Peak rating is not average charging power
Scope
NIO ET9 China-spec flagship platform, not a statement about all NIO cars
Evidence limits
The public figure is a manufacturer specification for ET9 hardware and matching infrastructure. It is not a Canadian public-charger compatibility test or a sustained charge-rate curve
