The EV maker revealed the ET7 electric sedan powered by its new 150 kWh battery achieved 1,044 km (650 miles) CLTC range on a single charge. And it still had 3% battery capacity remaining.
Beijing-based battery maker WeLion New Energy Technology developed the 150 kWh SSB. It was announced three years ago at Nio Day 2020 (held in January 2021) when Nio''s first sedan, ET7, was launched. The single cell has an energy density of 360 Wh/kg, while the whole pack has a 260 Wh/kg density.
The star here is the 150 kWh battery pack which has an energy density of 360 Wh/kg. It''s one of the highest-density mass-produced batteries for EVs and has been supplied by Beijing WeLion New Energy Technology.
At 1,044 kilometers, this is the driving range that Nio''s (NYSE: NIO) 150-kWh semi-solid battery pack has achieved on a single charge as seen in a real-life test, and is the longest range of any mass-produced electric vehicle (EV) to date.
Nio has demonstrated the real-life range of its new 150-kilowatt-hour Ultra Long Range battery by completing a 648-mile (1,044-kilometer) journey in China on a single battery charge.

Nio, a Chinese EV car maker, has just completed a battery challenge with its mass-produced ET7 sedan, driving for 1,044 km on a single charge.
The Nio ET7 arrived at its destination with a 3% state of charge, or 36 km of range, according to stats shared by the company.
Nio is best known for its battery swap technology and operates over 2,000 battery swap stations across China and Europe. According to the timeline shared by Nio, Li left a Nio battery swap station in Shanghai at 6:32 am with the car arriving – with the same battery – at its destination at 8:33 pm.
Given it''s winter, the temperatures during the testing were quite low which isn''t optimum for range testing.
Regardless, the car drove for extended periods with an average consumption of 132 Wh/km at an average speed of 84 km/hr.
"Today, we have witnessed that the range of smart pure electric vehicles has entered the era of one thousand kilometers. #Weilai ran 1044 kilometers on one battery. The 150kWh battery life challenge was completed, with a final score of 1044 kilometers!
“There has been a nationwide cold wave in recent days. When we set off from the Shanghai World Expo Center battery swapping station at 6:32 in the morning, the temperature was minus 2 degrees. The team did not expect the actual battery life to exceed 1,000 kilometers today. What exceeded everyone''s expectations was that ET7 and 150kWh battery pack."
Another key innovation being showcased by Li and the team on this trip is Nio''s autonomous driving suite which includes Nio pilot plus.
For comparison, a Nickel-Manganese-Cobalt (NMC) battery pack used in traditional long-range cars have a typical energy density of around 270 Wh/kg. Lithium-Iron-Phosphate (LFP) batteries which are used in most of the popular models in Australia are around 150 Wh/kg.
This is a great achievement for EV development as it showcases battery technology in mass-produced EVs and gives a glimpse of what''s to come in more mass-market electric cars in the coming years.

He is a mechanical engineer who spent the first 7 years of his career building transport infrastructure before starting carloop. He has a passion for cars, particularly EVs and wants to help reduce transport emissions in Australia. He currently drives a red Tesla Model 3.
(Nio concludes 150-kWh battery pack range challenge with 1,044 kilometers of ET7 driving range.)
"The 150-kWh battery range challenge is complete with a final score of 1,044 kilometers!" William Li, Nio''s founder, chairman and CEO, announced on the night of December 17.
Li set off from a battery swap station in Shanghai at 6:32 am yesterday and drove the ET7 sedan with the 150-kWh battery pack to a highway service area in Xiamen, Fujian province at 8:33 pm after 14 hours and 1 minute.
After 1,044 kilometers of driving, the ET7 had a remaining charge of 3 percent or a remaining CLTC mileage of 36 kilometers.
"This battery is currently the highest energy density battery pack mass-produced globally, with excellent safety performance, and more importantly all (Nio) models on sale can be flexibly upgraded to get this 150-kWh battery through the Nio battery swap system," Li added.
Li turned on Nio''s ADAS (Advanced Driver Assistance System) software, NOP+ (Navigate on Pilot Plus), for 92 percent of the journey, or 957 kilometers.
NOP+ not only fully demonstrates an excellent ability to relieve driving stress, but also makes a significant contribution to reducing power consumption, Li said.
It''s worth noting that the current testing conditions are not favorable for EVs, especially with the recent cold wave in several parts of China, with temperatures in Shanghai dropping below 0 degrees Celsius.
Li departed from Shanghai at -2 degrees Celsius, with a high of 12 degrees Celsius along the way, an average temperature of 20 degrees Celsius inside the vehicle, and a load of about 190 kilograms.
