PCU with vehicle electrical system assistance measure
Modern vehicles have a high energy consumption due to the many electrical consumers. As a result, there is a high demand on the battery particularly in phases in which the combustion engine is not running and the alternator supplies no energy (e.g. engine start/stop phases).
In order to protect the vehicle battery, a DC/DC converter is installed in the Power Control Unit (PCU) and an auxiliary battery in the engine compartment in the G30.
The preconditions for the direction of the energy management are calculated from the use of the vehicle. When the engine is running the auxiliary battery is charged from the conventional vehicle electrical system. During the phases in which the combustion engine is not running, e.g. automatic start/stop function, the energy is supplied from the auxiliary battery into the conventional vehicle electrical system.
The Power Control Unit PCU contains a control unit which is connected to the PT-CAN2 and a DC/DC converter with a power of 500 W.
On vehicles with the equipment electric active roll stabilization, this is supplied by the auxiliary battery in the engine compartment.
