Bi Lu said that the NIO ET9 will utilize a groundbreaking 900V high-voltage architecture, which means that with the further reduction of high-voltage wiring weight in the vehicle, the overall charging performance can be improved. Combined with NIO's power swap system, this will create the best solution for energy replenishment. Additionally, the new intelligent electric drive platform where the ET9 rides on will reduce the weight and size of electric motors, and incorporate various innovative technologies in the product design to achieve higher power density.

He added, together with a more secure and reliable high-voltage distribution redundancy architecture and a redundant dual-motor system in the front and rear, as well as NIO's self-developed big data system and intelligent control algorithms, the 900V electric drive system can be constantly monitored for health status and continuously optimize control parameters based on the user's driving behaviors, ensuring efficient, safe and reliable power output.

On December 19, NIO's Head of Vehicle Application Software, Mr. Xiao Baihong, announced on his personal Weibo account that the ET9 will be equipped with an intelligent fully chassis-by-wire system. He also stated that this is the only true fully intelligent drive-by-wire chassis in the world that combines three core hardware systems, greatly improving the vehicle's driving comfort, handling and safety.
