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.
