One more approach to battery swap stations.
Beijing–Hong Kong–Macau G4 Expressway
According to NIO, there are now 18 such stations up and running along the major highway: the G4 Beijing–Hong Kong–Macau Expressway. We assume that stations are spread over the length of 2,270 km (1,410 mi) by some 125 km (80 miles) or so.
One of the battery swap stations is installed next to a Tesla Supercharging station, which seems quite interesting as Tesla once tried the battery swap stations, but ended the project after a single demonstration station that wasn't too popular.
NIO intends to offer 12 free battery swaps annually for the first batch of customers, but in general it will be a paid service.
The ES8 is equipped with 70 kWh battery (from CATL) and can go more than 355 km (220 miles) (NEDC) or 500 km (310 miles) at 60 km/h (37 mph).
