Abstract

A vehicle electrical system is equipped with at least one high-voltage consumer, a DC charging connection a rechargeable battery, a rectifier and a changeover switch. The high-voltage consumer is connected to the rechargeable battery by the changeover switch via a first switching device in a first switching position of the changeover switch and is connected to the rechargeable battery by the changeover switch in a second switching position of the changeover switch via a second switching device, wherein the DC charging connection is connected to the rechargeable battery via the first switching device.

Claims (24)

1. A vehicle electrical system comprising:

at least one high-voltage consumer;

a DC charging connection;

a rechargeable battery; and

a changeover switch,

wherein the high-voltage consumer is connected to the rechargeable battery by the changeover switch via a first switching device in a first switching position of the changeover switch and is connected to the rechargeable battery by the changeover switch in a second switching position of the changeover switch via a second switching device,

wherein the DC charging connection is connected to the rechargeable battery via the first switching device.

2. The vehicle electrical system as claimed in claim 1 , further comprising an electric drive, which is connected to the rechargeable battery via the second switching device and which is connected to the high-voltage consumer by the changeover switch in a second switching position of the changeover switch.

3. The vehicle electrical system as claimed in claim 2 , wherein the electric drive is connected to a connection which connects the changeover switch to the second switching unit.

4. The vehicle electrical system as claimed in claim 1 , wherein the DC charging connection is connected to a connection which connects the changeover switch to the first switching device.

5. The vehicle electrical system (FB) as claimed in claim 1 , further comprising an AC voltage connection and a rectifier which is connected to one side of the changeover switch which is connected to the high-voltage consumer, or is connected to a point of a connection between the electric drive and the second switching device.

6. The vehicle electrical system as claimed in claim 5 , further comprising a first DC-DC converter via which the rectifier is connected to the side of the changeover switch which is connected to the high-voltage component or via which the rectifier is connected to the point of the connection between the electric drive and the second switching device.

7. The vehicle electrical system as claimed in claim 1 , wherein the high-voltage consumer is designed as an electric heater of an air-conditioning system or as an electrically heatable exhaust gas catalytic converter and/or as an additional DC-DC converter.

8. The vehicle electrical system as claimed in claim 1 , wherein the changeover switch and the first switching device and the second switching device are designed having two poles.

9. A vehicle electrical system comprising:

at least one high-voltage consumer;

a DC charging connection;

a rechargeable battery;

a rectifier;

a changeover switch; and

a controller which is connected to the changeover switch in a controlling manner and which has a driving state in which the controller controls the changeover switch to set the second switching position, and wherein the controller has a DC charging state in which the controller controls the changeover switch to set the first switching position,

wherein the high-voltage consumer is connected to the rechargeable battery by the changeover switch via a first switching device in a first switching position of the changeover switch and is connected to the rechargeable battery by the changeover switch in a second switching position of the changeover switch via a second switching device, and

wherein the DC charging connection is connected to the rechargeable battery via the first switching device.

10. The vehicle electrical system as claimed in claim 9 , wherein the controller is also connected in a controlling manner to the first switching device and to the second switching device, wherein the controller in the driving state controls the first switching device in an open state and controls the second switching device in a closed state and wherein the controller in the DC charging state controls the first switching device in a closed state and controls the second switching device in an open state.
