Nio (NYSE: NIO) today saw its cumulative battery swap service reach 20 million, with an average of 45,000 services provided daily.

The electric vehicle (EV) maker announced the milestone today on its mobile app, just 273 days, or nine months after it saw its 10 millionth battery swap service on July 4 of last year.

It took the company 1,506 days, or more than four years, to see its first 10 million battery swap services provided.

On February 5, more than 60 percent of the power Nio provides to owners was provided through battery swap stations, and the facility has become a favorite way for Nio customers to replenish their vehicles, it said.

Currently, Nio's battery swap stations provide an average of more than 45,000 services a day, which equates to an average of one Nio vehicle receiving a fully charged battery from these stations every 1.9 seconds.

The 20 million battery swap services can support more than 5,106 million kilometers of driving and reduce carbon emissions by about 550,286 tons, the company said.

Nio's battery swap stations not only provide vehicles with fully charged batteries but also allow owners to easily upgrade their battery packs.

To date, Nio has provided 63,136 battery upgrades to customers, allowing them to continue to enjoy the benefits of battery technology advancements, the company said.

As of today, Nio has 1,327 battery swap stations and 2,442 charging stations in China, according to data monitored by CnEVPost.

The company's goal is to add 1,000 battery swap stations this year, bringing the facility to 2,300 in China by the end of 2023.

The aggressive infrastructure goal is one of the ways to boost sales, and the company's co-founder and president, Qin Lihong, said in a recent interview with local media that the company hopes swap stations will serve partly as showrooms in less developed cities.

On April 1, William Li, founder, chairman and CEO of Nio, reiterated that the company's of battery swap station network is open to other brands and compared the service to cloud services.

Nio's battery swap stations have a good degree of adaptability and the time has come to offer their output to the outside, Li said.
