On January 9, 2021, NIO Day 2020 will be held in Chengdu.


At this year’s NIO DAY, NIO released the first sedan ET7, which is also NIO’s first smart electric flagship sedan with autonomous driving capabilities.



The starting price before the subsidy is 448,000 yuan, the starting price of the BaaS program is 378,000 yuan before the subsidy; the first version is priced at 526,000 yuan before the subsidy, and the BaaS program is priced at 398,000 yuan before the subsidy, starting today Yu Weilai App is open for reservations, and delivery is expected to start in the first quarter of 2022.











According to the official introduction of NIO, ET7 has applied the latest NAD (NIO Autonomous Driving) technology.


The NIO Super Sensing System Aquila is equipped with 33 high-performance sensing hardware, including 11 8-megapixel high-definition cameras and 1 ultra-long-distance high-precision lidar. The NIO supercomputing platform Adam is equipped with four NVIDIA DRIVE Orin chips with a computing power of up to 1016TOPS.







So far, NIO has established full-stack autonomous driving technology capabilities, and will gradually realize easy and safe point-to-point autonomous driving experience in high-speed, urban, parking, and power-on scenarios.


The complete function of this set of NAD will be provided with a monthly subscription model, namely ADaaS (AD as a Service), and the service fee is 680 yuan per month.


In terms of the whole vehicle, the NIO ET7 has a length of 5098mm, a width of 1987 mm, a height of 1505 mm, and a wheelbase of 3060mm. It applies the second-generation digital cockpit technology of NIO, and is equipped with the third-generation digital cockpit computing platform of Qualcomm, which has stronger in-vehicle mobile internet and communication capabilities. The world's first in-vehicle artificial intelligence system NOMI continues to evolve; 23 speakers are standard with an output power of 1,000 watts, creating the first 7.1.4 in-vehicle immersive sound system.



ET7 uses 180kW front permanent magnet motor + 300kW rear induction motor, it only takes 3.9 seconds to accelerate from zero to 100 kilometers, and the braking distance from 100 kilometers to zero is 33.5 meters; the drag coefficient is as low as 0.23Cd, which is suitable for the application The second-generation high-efficiency electric drive platform of the silicon carbide power module has an overall improvement in energy efficiency. It is equipped with a 70kWh battery pack and NEDC has a battery life of over 500 kilometers and a 100kWh battery life of over 700 kilometers.





It is worth noting that in this NIO Day, Wei Lai also released a 150kWh battery pack. The battery pack uses advanced mass-produced solid-state battery technology, which can achieve a 50% increase in energy density.


It is reported that the 150kWh solid-state battery adopts the solid-liquid electrolyte of the in-situ curing process to ensure the safety of the cell; the silicon-carbon anode with the inorganic prelithiation process and the ultra-high nickel cathode with the nano-scale coating process are used in The energy density rises while ensuring the life span and improving the charging efficiency.



Nio’s 150kWh battery, using solid-state battery technology, can achieve 360Wh/kg energy density


Through material and process innovation, an ultra-high energy density of 360Wh/kg has been achieved, and all NIO models can be upgraded. Equipped with a 150kWh battery pack, all NIO models have long NEDC battery life. The 2018 ES8 exceeds 730km, the new ES8 exceeds 850km, ES6 and EC6 exceeds 900km, and the ET7 exceeds 1,000km.


In terms of energy supplements, according to Weilai, more than 66% of users have installed home charging piles; the overcharging network has been completed with 100 supercharging stations and 792 supercharging piles; Weilai’s charging The map is connected to more than 285,000 three-way fast charging piles, covering more than 300 cities across the country. In September 2020, Weilai released the Power Up Plan, planning to deploy 30,000 20kW DC piles nationwide. In December 2020, users helped NIO open up a destination charging route from Chengdu to Everest Base Camp, which is more than 2,900 kilometers.


At the same time, NIO has built 177 swap stations across the country, with a total of more than 1.49 million power swaps. On average, one NIO will start from a full power swap station every 12 seconds. In order to continuously improve the battery swap service experience, NIO officially released the second-generation swap station. The second-generation power station has a single-day service capacity of 312 units and is unattended. The vehicle can be automatically parked, and the self-service power replacement can be started in the vehicle with one button, and the user does not need to get off the vehicle.

NIO will speed up the layout of power replacement stations, and plans to reach 500 power replacement stations nationwide by the end of 2021.


In addition, Weilai released the 'Blue Dot Program' to encourage users to implement low-carbon environmental protection missions. Li Bin, the founder, chairman and CEO of Weilai, introduced: 'Car owners can authorize emission reduction transactions through Weilai APP For NIO, NIO will conduct authentication transactions on behalf of car owners, and the income will be returned to users in the form of points. Among them, points as of December 2020 will be prepaid to users before the Spring Festival.' To further realize Blue Sky Coming Vision.


As of December 31, 2020, Weilai has delivered a total of 75,641 units. 'The NIO community is constantly growing. The user's love and trust in NIO has always been the driving force for NIO. The ET7 released by NIO Day this time is a new start for smart electric vehicles. Next, NIO will be in the product and technology Continue to invest in the field, and accelerate the construction of the service network, to bring users a better smart electric vehicle experience.'
