Abstract
A vehicle electrical system is equipped with a DC charging connection, a rechargeable battery, a DC-DC converter and an electric drive. The DC-DC converter has a first side that is connected to a connecting point via a first switching device. The DC-DC converter has a second side to which the electric drive is connected and which is connected via a second switching device and to the connecting point. The connecting point is connected to the rechargeable battery. The DC charging connection is connected to one side of the first switching device that is connected to the first side of the DC-DC converter.
Claims10
A vehicle electrical system comprising:
- a DC charging connection;
- a rechargeable battery;
- a DC-DC converter;
- and
- an electric drive,
- wherein the DC-DC converter has a first side that is connected to a connecting point via a first switching device and the DC-DC converter has a second side to which the electric drive is connected and that is connected via a second switching device and to the connecting point, and
- wherein the connecting point is connected to the rechargeable battery and the DC charging connection is connected to one side of the first switching device that is connected to the first side of the DC-DC converter,
- wherein the first switching device connects two potentials of the first side of the DC-DC converter to two potentials of the connecting point, and
- wherein the first switching device provides a switching element for one of the potentials and provides a diode device for the other potential, a forward direction of said diode device corresponding to a direction of current flow of a charging current by which electrical energy is conducted from the DC charging connection to the rechargeable battery.
