Introduction
The Electrical Machine Electronics (EME) is primarily used as control
electronics for the electrical
machine. It is also responsible for converting the direct current voltage from
the high-voltage b

ECO PRO
The HYBRID ECO PRO driving mode rigorously supports a driving style that
reduces consumption
and its attribute corresponds to the combination of ECO PRO and Auto eDrive of
the predecessor
model. In this driving mode the G20 PHEV has its maximum overall range.
Essentially the follow

Convenience charging electronics
The convenience charging electronics enable communication between the vehicle
and charging
station of the AC voltage supply in order to charge the high-voltage battery
unit. The convenience
charging electronics convert the AC voltage into high-voltage direct curre
