The Nio (NYSE: NIO) ET7 with a 150-kWh semi-solid-state battery pack achieved a real-world range of up to 1,070 kilometers, according to data released today by the electric vehicle (EV) maker.

Nio (NYSE: NIO) conducted a 150-kWh battery pack range challenge with the 2,024 ET7 sedan on April 16, the first test of the ultra-long-range battery pack since its mass production.

Earlier this month, the first mass-produced 150-kWh battery pack rolled off the assembly line. On December 18, 2023, Nio founder, chairman, and CEO William Li drove a 2023 ET7 with a 150-kWh semi-solid-state battery in a range challenge, with 36 kilometers of remaining CLTC range after 1,044 kilometers of driving.

For the latest range challenge, Nio used three 2024 ET7s with 150-kWh battery packs on three different routes: from Kunming, Yunnan to Zhanjiang, Guangdong; from Beijing to Hefei, Anhui; and from Shanghai to Xiamen, Fujian.

The 2024 ET7 ran out of power after traveling 1,070 kilometers on the Kunming-Zhanjiang route. Here are the details of the test on the route:

Energy consumption: 12.7 kWh per 100 km.

Driving time: 12.8 hours.

Length of time to complete test: 15.9 hours.

Average speed: 83.7 km/h.

Maximum speed: 118 km/h.
