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 Electrical Machine Electronics and convenience charging electronics (KLE)
are cooled by the low-
temperature coolant circuit.
