Chinese automaker launched a flagship electric car with an available 150-kilowatt-hour battery pack last week with scheduled deliveries starting in early 2022. It could be the first mass-produced passenger car anywhere in the world—yes, before Tesla—to have solid-state battery technology.
The car is touted to be equiped with a 150-kwh pack battery that won’t be exclusive to the ET7. The ability to fit the larger-capacity pack into the same physical space as the 70-kwh and 100-kwh packs offered in current Nio electric cars indicates claims of greater efficiencies, and energy density for solid-state batteries.
Nio quotes a range of over 621 miles for the ET7 (as measured on the very optimistic NEDC testing cycle), but the sedan will also be sold with the existing 70-kwh and 100-kwh packs, affording estimated ranges of 310 miles and 435 miles, respectively.
