NIO's most expensive production car is coming! 800,000 pre-sales, equipped with a number of self-developed core technologies

On December 23, NIO Day 2023 was officially held in Xi'an.

The heaviest thing has to be a new car. At this annual press conference, Li Bin showed off the executive flagship sedan ET9, which is 5,325 mm long, 2,016 mm wide, 1,620 mm high, and has a wheelbase of 3,250 mm.

In this car, it will also be the first to use many of the latest technologies just released by NIO, including the first self-developed intelligent driving chip - Shenji NX9031, the global 900V high-voltage architecture, 46105 large cylindrical battery cells and battery packs, SkyRide Tianxing chassis system, flagship-level safety standards.

First of all, in terms of intelligent driving chips, this car uses the first self-developed intelligent driving chip officially released by NIO at this event - Shenji NX9031. Li Bin said that the computing power of its self-developed Shenji chip can reach the computing power of the four flagship intelligent driving chips in the industry. It is understood that the flagship intelligent driving chip currently used by the industry is generally the NVIDIA Orin X chip, and the previous Weilai's intelligent driving system used 4 NVIDIA Orin X chips, with a computing power of 1060TOPs, that is to say, Wei's self-developed Shenji chip, one can reach 1000+TOPs computing power. In addition, the NIO ET9 will use dual Shenji chips in all vehicles, and the other one will be backed up in milliseconds to achieve secure redundancy in computing.

In terms of batteries, it will use 46105 large cylindrical cells and battery packs developed by NIO, with an energy density of up to 292Wh/kg per cell, a utilization rate of 84% and a capacity of 120kWh, and also support 5C fast charging, which can achieve 255 kilometers of energy replenishment in 5 minutes.

In terms of charging, ET9 is equipped with a self-developed 900V high-voltage architecture in the whole domain, with the highest voltage of 925V vehicle, a peak charging power of 600kW, and a peak charging current of 765A.

In addition, the car will also feature the "SkyRide chassis system", which integrates the three core hardware systems of steer-by-wire, rear-wheel steering and fully active suspension.

The steer-by-wire adopts telecommunication transmission, which does not have the constraints of the shape and space of the traditional mechanical structure, which can further improve the accuracy and corresponding speed of the operation. The maximum rear-wheel steering angle is 8.3°, enabling a minimum turning diameter of 10.9 meters. The fully active suspension adopts a hydraulic full active suspension system, which highly integrates the shock absorber with the active suspension electric drive unit to further enhance comfort.

In terms of safety, NIO has made seven safety redundancy, including drive, braking, steering, perception, communication, and power distribution in addition to the aforementioned calculations, ensuring the safety of the vehicle to the greatest extent.

The NIO ET9 price is also quite "beautiful", with a pre-sale price of 800,000 yuan, but the delivery will not be until the first quarter of 2025. In other words, although it is equipped with many core technologies, it has not yet reached mass production, which means that these technologies cannot be verified in practice, and more importantly, it means that NIO may usher in the embarrassment of new product vacancies next year.

Although there may be vacancies in new car products, NIO still has big moves in energy replenishment next year.

The first is on energy supplements. At this event, NIO released two new energy replenishment products: a 640kW fully liquid-cooled ultra-fast charging pile, and a fourth-generation battery swap station.

The 640kW fully liquid-cooled ultra-fast charging pile has a peak charging power of 640kW, a maximum output current of 765A, a maximum output voltage of 1000V, and a liquid-cooled charging cable weighing 2.4kg. The product will be put into service in April next year.

In the fourth generation of battery swap stations, the number of battery bins has increased to 24, and the maximum service per day can reach 480 times, reducing the time of a single swap by 22%. In addition, the intelligence level of the new generation of battery swap stations has also been greatly improved, equipped with 4 NVIDIA Orin X chips, the computing power of the whole station has reached 1016TOPS, and there are 6 ultra-large vision lidars.

It is worth noting that this is also the most important product in the next stage of NIO's battery swap business, and this generation of charging stations will officially support multi-brand shared battery swapping, that is to say, the battery swap cooperation signed by NIO, Changan and Geely will be officially implemented on this generation of products.

In addition, Li Bin also officially announced next year's goals at the event: the number of battery swap stations will increase by 1,000 to more than 3,310, and the number of charging piles will be increased by 20,000 to more than 41,000.
