High-voltage interlock loop
The SME control unit evaluates the signal of the high-voltage interlock loop
and checks whether there
is an open circuit with this circuit. In the event of an open circuit, the
battery management electronics
control unit can cause the high-voltage system to perform a qu
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
