From the China the first one arrives 900 Volt electric car which, compared to traditional vehicles, can accumulate 250 km of autonomy in 5 minutes, with the aim of speeding up supplies. The innovation comes from the Chinese electric car manufacturer NIO which presented its new electric drive system called Thunderwhich will be used on the future one NIO ET9.
900 Volt electric car, characteristics
The Nio ET9 is the first electric car 900 volts. Technology, called Thunder EDS, uses electric motors integrated into the front and rear axles. The new powertrains are 30% lighter and their longitudinal dimension has been reduced reduced by 280 mmimproving internal space and reducing energy consumption.
Thanks to the silicon carbide power module from 1,200V and at the power density of 1,315 kW/L, can bear more 300,000 work cycles. The new liquid cooling system increases engine operating time by 30%. maximum power.
Fast charging in 5 minutes
The Thunder system also allows you to reduce charging times to the columns Fast HPCwith a withdrawal of 250 km estimated in 5 minutes. The car, in fact, can support peak charges of up to 600 kW and 765A.
Additionally, you can use the battery swap to fully recharge in just one hour three minutestaking advantage of the new ones Power Swap Station 4.0 or the 640 kW liquid-cooled columns. Nio aims to build 1,000 battery replacement stations and 20,000 charging stations in 2024 alone.
Nio ET9 features
The Nio ET9, with its dimensions of 5,325 mm long, 2,016 mm wide1,620 mm high and 3,250 mm wheelbase, features 525 patents and 17 world premiere technologies. The Skyride frame it is the first intelligent chassis “by wire” in the world, managing steering and chassis adjustments without physical connections between steering wheel and wheels.
The traction is all-wheel drivewith an a permanent magnets from 340 kW at the rear and an induction unit from 180 kW at the front, for a total power of 520 kW, or 707 HP. The front engine weighs only 79kg and has a power density of 4.3 kW/kg, the highest among synchronous electric motors. The rear one, however, has a power density of 2.6 kW/kg.
As for the passenger compartment, there is enough space for 4 people to sit on independent seatselectrically adjustable, with the rear ones tiltable up to 45 degrees. There are also 24 patented technologies inside.
Solutions for comfort and safety include seven electric blinds and advanced technologies such as level 2 assisted driving and the SkyOS operating system, ensuring intuitive management of the car's functions.
Nio ET9 price
The Nio ET9 is a luxury car that aims to challenge the Porsche Taycan and the Model S Plaid in terms of power and performance. The estimated price in China is 800,000 yuan, equivalent to approximately 105,000 euroswhile in Europe it could reach i 140,000 euros.
The high cost does not make the car accessible to everyone, but it is interesting to note how Nio uses it to test new technologies that could also become available on more “popular” models.
