- a device for controlling a power supply of a vehicle electrical system of a vehicle can be connected to the consumer, comprising a first energy storage for providing electrical energy to a starter, a generator for generating a generator voltage and a first controllable
- Switching element which is provided between the first energy storage and the generator, and which is designed such that it allows a current flow in one direction only from the first energy storage to the generator during operation of the vehicle.
- the switching element may also have a further switching state, in which the switching element behaves like a conductor.
- the controllable switching element is a field-effect transistor, in particular a MOSFET. Since field-effect transistors can be switched with low gate voltages and minimal time delay, it is therefore possible to quickly detect changes in the current flow via the controllable switching element or strong ones
- a field-effect transistor or field-effect transistors connected in parallel can be arranged so that the forward direction of its intrinsic diode or diodes is the direction of the first
- the device comprises a further energy store for providing electrical energy to the consumers, which is arranged such that the first controllable switching element is arranged between the first energy store on the one hand and the generator and the further energy store on the other hand.
- a charging circuit is provided, wherein the charging circuit is formed during operation of the vehicle such that the first energy storage is charged to a voltage UE1 which is equal to or greater than the voltage of the second energy storage UE2 and is smaller than the voltage of the generator.
- the first energy store is preferably designed as a double-layer capacitor and the second energy store as a battery.
- Energy storage provides electrical energy to the starter for a warm start and / or attenuates voltage fluctuations by the consumer, wherein the second energy storage provides electrical energy for the starter during a cold start.

- Switching element of the starter is optionally connected to the first switching element or directly to the second energy storage. Due to the higher voltage of the second energy storage more energy can be stored, which increases both the restartability and the voltage stability of the electrical system.
- the DC / DC converter transforms the voltage from the second energy store down to the on-board network consumers. By selectively connecting the second switching element, which operates as a changeover switch, it is prevented that the higher voltage of the second energy store can have repercussions on the second area via the first switching element.
- the setpoint voltage of the second energy store is less than or equal to a setpoint voltage of the generator and of the first energy store, wherein the second energy store is connected to the starter via a second switching element.

- the second energy store is designed as at least one capacitor, more preferably a double-layer capacitor. It can also be provided that the energy storage is designed as a capacitor pack, wherein in each case a plurality of capacitors in series and these series circuits are connected in parallel. However, it is also possible to form the second energy store as a battery.
- the first energy store is preferably designed as a battery, which is possibly composed of a plurality of battery cells. In principle, the first energy store can be off
- Capacitors are formed.
- the first switching element is designed as a MOSFET.

- the diagnostic module can, for example, detect the current from the energy store and / or determine the SOC (state of charge) and / or SOH (state of health). If the diagnostic module then detects a defect (eg insufficient charge state or line break between the battery cells), the second energy store is connected to the starter.
- the diagnostic module may interconnect the first and second regions via the first switching element if the first energy storage needs to be charged by the generator. The diagnostic module can switch the switching elements directly or provide its data to a higher-level control unit.

- the second switching element is designed as a power relay.
- the motor vehicle electrical system is formed with a control unit, by means of which a start-stop system is executable.
- the start-stop system can be integrated into an engine control unit.
- the start-stop system also accesses the data of the diagnostic module, so that, for example, the start-stop system is deactivated when the first energy store is poorly charged.

After the engine has started, the starter switch 3 is opened again. The DC / DC converter 10 can now be operated in a different direction so that the second energy store 9 is recharged by the generator 6, for which purpose the DC / DC converter 10 converts the generator voltage upwards. If the diagnostic module 5 determines that the SOC of the first energy store 4 has dropped, the first switching element 12 can be switched to the second switching state. Then the generator 6 can charge the first energy store 4.
- the diagnostic module 5 detects that the first
- Energy storage 4 is not sufficiently charged or has another defect (eg Batterieschriss, connection tear between two battery cells 16, etc.), so the second switching element 13 is switched to the second switching state. This is the second one
- Energy storage 9 is connected directly to the first energy storage 4 and the starter 2 and can supply the starter 2 with its high voltage of about 20 - 24 V.
