Here is a teaser video shared by NIO on its app about its third-generation battery swap station.

Three patents published a month ago show that NIO's next-generation battery swap station will not only be able to store more battery packs, but will also have greater compatibility in order to serve vehicles with different-sized packs.

One of the patent documents showed that the new battery swap station will be able to store up to 22 battery packs.

NIO's initial 200 battery swap stations are first-generation facilities that store up to five batteries and have a maximum daily service capacity of 120.

The company put its first second-generation battery swap station into service on April 15, 2021, with storage for up to 13 batteries and a maximum daily service capacity of 312.

At the second annual NIO Power Day event on July 6, NIO co-founder and president Qin Lihong previewed the company's third-generation battery swap station, saying it would have a larger capacity and more flexible layout.

NIO's third-generation battery swap station was nearing the end of its development and was being tested and will be detailed by the end of the year or early next year, Qin said at the time.

The company today put three new battery swap stations into operation, bringing the total to 1,277, according to data monitored by CnEVPost. NIO aims to bring the number to more than 1,300 by the end of the year.

NIO also has 2,226 charging stations in China as of today, offering 13,030 charging piles and access to more than 610,000 third-party charging piles.
