Although the high-voltage battery unit of the G20 PHEV can also be partially
charged by energy

The "charging" procedure for an electric vehicle corresponds to "refuelling"
a conventionally driven
vehicle. Accordingly, in this chapter "charging" means:

The electrical machine in the G20 PHEV is structured as an inner rotor.
"Inner rotor" means that the
