The interior is divided down the middle by a so-called executive bridge. It provides the rear seat occupants with fold-out tables and a 10-litre mini refrigerator. The rear also receives up to seven electric sunshades.
At the heart of the new four-seat crossover is a newly developed 900-volt electric architecture combined with a proprietary 1200v silicon carbide (SIC) power module. It permits battery charging at up to 600kW and peak charging curve of 765 amps – sufficient for a 159 mile top-up in electric energy in 5 minutes, according to Nio.
The adoption of the new electric architecture has seen Nio further reduce the size and weight of the electric motors and wiring harness in the ET9 compared to the existing 800-volt system used by the ET7.
Further developments incorporated on the big crossover include Nio’s new NX9031 AD chip set. The 5 nm, 32-core automotive grade processor has over 50 billion transistors and is claimed to be capable of running over 6 trillion commands per second at speeds 75 per cent faster than the automotive industry average, says Li. This allows concurrent processing for sensing, computing, planning and control.
Power for the ET9 is supplied by two newly developed electric motors. Included is what Nio describes as the world’s first 925-volt W-Pin motor. Capable of operating at up to 20,000rpm, it is mounted at the rear and develops up to 340kW. The front houses an induction motor with a power density of up to 2.6kW/kg and a peak output of 180kW.
Electric energy is provided by a swappable 120kW lithium-ion battery. It uses Nio’s new 46105 cylindrical cells and has a cell energy density of 292Wh/kg.
