BMW 5 Series: 24 V Electronic Power Steering
The greater weight of the engines in the G30 on vehicles with 8-cylinder
engines results in a higher
front axle load. This has the effect that the required power of the steering
assist increases. Due to
these high currents, it is necessary to increase the voltage supply of the EPS
to 24 V.
An auxiliary battery, separating element and a charging unit for the auxiliary
battery are required for
this. These components are installed in the luggage compartment of the G30.
The charging unit monitors the state of charge and also charges the auxiliary
battery using a DC/DC
converter. The EPS is only supplied with 24 V once this relay has been
activated. The EPS can also be
operated with 12 V in the event of a fault.
