Nio ET7 goes 650 miles on 150 kwh with semi-solid-state battery

A Nio ET7 with the automaker’s new 150-kwh battery pack traveled 650 miles on a single cost, the corporate claims.

This was achieved by a bunch of drivers, together with Nio founder and CEO William Li, on a 14-hour journey between the Chinese language cities of Shanghai and Xiamen, in response to an organization press launch. Nio claims the journey used 97% of the automotive’s battery capability.
