Electrical machine electronics
The function of the Electrical Machine Electronics (EME) is to activate and
regulate the permanently

In the G20 PHEV an acoustic protection for pedestrians is used as standard.
To protect pedestrians
a distinctive sound created specially for electric BMW models is generated
during electric driving.
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
Three signs are attached to the housing of the high-voltage battery unit: 1
type plate and 2 warning
stickers. The type plate provides logistical information (e.g. part number) and
the key technical data
(e.g. nominal voltage). The warning stickers point to the lithium-ion technology
on the one h
