To guarantee the thermal operating safety of the electrical machine in every
situation, it is cooled with
coolant in the G20 PHEV. For this, the electrical machine is integrated in the
coolant circuit of the
transmission.
To cool the stator coils, the transmission oil is directed through a c
The DC/DC converter in the Electrical Machine Electronics of the G20 PHEV is
able to adopt the
following operating modes:
Standby (also in the event of a component fault or short circuit, power
electronics off)
Buck mode (energy flow to the low-voltage side, converter adjusts
voltage on
