Nio's F1 plant stopped production for five days between July 29 and August 2 to undergo a production line upgrade, according to local media.

Nio's vehicles are produced at two factories in Hefei, Anhui province, in eastern China, including the F1 factory, the JAC Nio advanced manufacturing base, and the F2 factory in NeoPark.

Originally, both the old ES6 and ES8 were produced at the F1 plant, but to ensure production capacity, the F1 plant is now mainly producing the new ES6, while production of the new ES8 has been shifted to the F2 plant, according to Caixin.

Nio launched the new ES6, based on the latest NT 2.0 platform, in China on May 24, with its deliveries starting on the night of the launch.

The company launched the ET5 Touring on June 15, and deliveries began on June 16.

Deliveries of the new ES8 in China began on June 28, and the Nio flagship SUV was launched on December 24, 2022 on Nio Day 2022.

With capacity climbing following the intensive launch of new models, Nio delivered a record 20,462 vehicles in July, the first time since its inception that it has seen deliveries exceed the 20,000 mark.

The Nio ES6 delivered 11,118 units in July, contributing 54.33 percent of Nio's monthly deliveries, data monitored by CnEVPost showed.

The ET5 Touring delivered 3,662 units in July, contributing 17.89 percent of Nio's deliveries in the month.

Nio ES8 delivered 1,917 units in July, a 226.02 percent increase from June and a new high since December 2021.

Apart from the factory production, Caixin's latest report also mentions the cost of Nio's battery swap stations.

Nio's investment cost for a single battery swap station averages between RMB 4 million ($550,000) and RMB 5 million, and it will invest more than RMB 4 billion in these facilities in 2023, the report said, citing a source from China Automotive Technology and Research Center (CATARC).

Investment costs for battery swap stations include site costs, equipment acquisition costs, construction costs, battery costs, and operating costs including equipment maintenance and power purchases, the report noted.

Nio aims to add 1,000 battery swap stations in 2023, taking the facility's total to 2,300 at the end of the year.

As of August 21, Nio had 1,673 battery swap stations in China, data monitored by CnEVPost showed.

Since Nio's first battery swap station went live, the company has provided more than 27 million battery swap services.

Notably, Nio has never disclosed the cost of each battery swap station, although previous reports had suggested that each first-generation battery swap station cost RMB 3 million to build, with the cost of the second-generation of the facility dropping to RMB 1.5 million.

Nio's cost to bring a second-generation battery swap station into operation is about RMB 2.5 million, and the capital expenditures associated with these facilities will not bring financial pressure, Yu Xiaoli, an analyst at Chinese brokerage Industrial Securities, said in an October 2021 research note.
