Nio said a month ago that its 150-kWh ultra-long-range battery pack will come online in the second quarter, and is the largest capacity battery pack mass-produced in China's passenger car segment.

Nio has already filed for the use of the 150-kWh pack in its models last year, capable of providing a range of up to 1,000 kilometers on a single charge in several models.

On December 17, 2023, Nio founder, chairman, and CEO William Li drove an ET7 sedan with a 150-kWh battery pack to complete a real-life range challenge for the pack.

After 1,044 kilometers of driving, that ET7 had a remaining charge of 3 percent and a remaining CLTC range of 36 kilometers, according to Nio's announcement at the time.

The electric vehicle (EV) maker's models support battery swap, which allows owners to replace a dead battery with a fully charged one in a matter of minutes at battery swap stations, making it possible to put new battery technologies into use quickly.

The 150-kWh ultra-long-range battery pack will be put into service in the second quarter, Nio said on March 5 in its fourth-quarter 2023 earnings highlights posted to its Chinese-language social media accounts.

This is the largest capacity battery pack mass-produced in the domestic passenger car segment, with Nio models equipped with the pack boasting a range of up to 1,055 kilometers, it said.

As it is a new technology, the 150-kWh battery pack is currently costly, and Nio co-founder and president Qin Lihong mentioned in February 2023 that the pack costs about the same as an ET5.

The ET5 is Nio's least expensive model at the moment, with a starting price of RMB 298,000 ($41,400) including the battery.
