NIO ET9 mass production version unveiled: 900V platform + semi-solid battery

Recently, NIO officially released the ET9 mass-produced version of the car. This flagship sedan has become the focus of the industry with its 900V high-voltage platform and semi-solid-state battery technology. As the technology master of the NIO brand, ET9 not only refreshed the upper limit of electric vehicles, but also demonstrated the breakthrough of Chinese brands in the field of high-end smart electric vehicles. The following is a detailed summary:

1. At a glance of core parameters

2. Analysis of technical highlights

1.900V high voltage platform: Compared with the mainstream 400V platform, the power transmission loss is reduced by 50%, the wire harness is reduced by 30%, and the comprehensive efficiency is improved by 25% with the self-developed 900V silicon carbide electric drive system.

2.Breakthrough of semi-solid battery: It adopts battery technology jointly developed by NIO and Weilan New Energy, with an energy density of 360Wh/kg, supports low-temperature environment use in -30℃, and has a cycle life of more than 2,000 times.

3.Smart chassis system: Equipped with a fully active suspension, the response speed is 5 times faster than the traditional air suspension, and it is equipped with rear wheel steering (maximum 8.3° rotation angle), which achieves flexible control over 5 meters of vehicle length.

3. Horizontal comparison of competitors

4. Industry impact analysis

1.High-voltage platform popularization accelerates: The 900V architecture of ET9 will promote the upgrading of industry voltage standards, and it is expected that mainstream high-end electric vehicles will generally adopt platforms above 800V in 2025.

2.Solid state battery commercialization: As the first model equipped with mass-produced semi-solid state batteries, its actual performance will directly affect the choice of next-generation battery technology routes.

3.Reshaping the high-end market structure: The 800,000-level pricing directly challenges the BBA flagship sedan, and cooperates with the NIO battery swap network (2,300 seats have been built), forming a differentiated competitive advantage.

5. User focus

According to online public opinion monitoring, the top three issues that consumers are most concerned about:

6. Marketing time planning

ET9 is expected to start delivery in the first quarter of 2025, and reservations have been opened on the NIO APP with a deposit of 50,000 yuan. The official revealed that the battery rental solution (BaaS) will be launched simultaneously, and the monthly fee standard is to be announced.

As a milestone for Chinese brands to impact the luxury market, NIO ET9's technological breakthroughs show a new direction for the development of electric vehicles. As the mass production process advances, its market performance will test the recognition of high-end consumers for technological innovation and brand value.
