On March 27, Nio introduced that the mass-production model of the 900V electrical drive system (EDS) known as “Thunder” had rolled off the manufacturing line. This event conveniently coincided with the manufacturing of the one-millionth Nio’s EDS. The upcoming Nio ET9 would be the model’s first car to undertake the Thunder EDS.

Nio 900V Thunder EDS
Nio has supplied some particulars on the 900V Thunder EDS. First, the electrical motors within the entrance and rear axle built-in into this electrical drive system turned 30% lighter, and their longitudinal dimension was decreased by 280 mm. The lighter weight improves the automotive’s vitality consumption, whereas the smaller dimension boosts the residing house within the cabin.
Nio talked about that the ET9 makes use of the world’s first 925V W-Pin synchronous everlasting magnet electrical motor, which has a peak energy output of 340 kW. In the meantime, it weighs simply 79 kg, leading to an influence density of 4.3 kW/kg. Within the entrance axle, the ET9 has an asynchronous induction motor with a peak energy of 180 kW. Its energy density is 2.6 kW/kg. Nio says it’s the world’s highest energy density amongst asynchronous electrical motors.

The 900V Thunder EDS isn’t nearly electrical motors and uncooked energy. It makes use of the 1200V silicon carbide energy module with an influence density of 1315 kW/L and might deal with over 300,000 energy cycles. It additionally has steady wave winding know-how that provides 86% of the motor’s energy. Final however not least, the EDS options the revised liquid-cooling system, which will increase the motor’s peak steady energy by 30%.
In the present day, the primary mass-produced 900V Thunder EDS has rolled off the manufacturing line. As talked about, the primary automotive to get this powertrain is the Nio ET9. It can enter the Chinese language market in 2025.
Extra on Nio ET9
The Nio ET9 is the model’s flagship fastback, unveiled on Nio Day 2023 in December. It’s already obtainable for preorder with a value of 800,000 yuan (~110,000 USD). Its deliveries are scheduled for Q1 2025. Its dimensions are 5324/2016/1620 mm with a wheelbase of 3250 mm. It has a 120-kWh battery on board. Its mixed peak energy output reaches 520 kW or 697 hp.
