Abstract

A vehicle electrical system for a motor vehicle. An electrical energy store and at least one component of the vehicle electrical system, this component being connected to the energy store by at least one connection providing at least one electrical line connection to the energy store. A temperature-control fluid can be transported to and/or from the component of the vehicle electrical system that is associated with it by the at least one connection.

First claim

The invention claimed is:

1. A vehicle electrical system for a motor vehicle, comprising:
an electrical energy store and at least one component of the vehicle electrical system, this component being connected to the energy store by at least one connection providing at least one electrical line connection to the energy store, wherein a temperature-control fluid can be transported to and from the component of the vehicle electrical system that is associated with it by the at least one connection.

2. The vehicle electrical system according to claim 1 , wherein at least one of the at least one electrical line connection(s) is designed as a hollow unit, on the inside of which the temperature-control fluid can be transported, and at least one of the at least one connection includes a flexible tubing or a pipe for transporting the temperature-control fluid, wherein the electrical line connection runs inside or outside the pipe or the flexible tubing.

3. The vehicle electrical system according to claim 1 , wherein at least one of the at least one component(s) of the vehicle electrical system is associated with two connections, wherein a first connection provides a forward run of the temperature-control fluid to the component of the vehicle electrical system and a second connection provides a return run of the temperature-control fluid from the component of the vehicle electrical system, and a connection connected to at least one of the at least one component(s) of the vehicle electrical system has fluid channels providing a forward run of the temperature-control fluid to the component of the vehicle electrical system and a return run of the temperature-control fluid from the component of the vehicle electrical system.

4. The vehicle electrical system according to claim 3 , wherein at least one connections on the side of the component of the vehicle electrical system and on the side of the energy store has a common connection element for the electrical contacting of the at least one line connection and for transporting the temperature-control fluid in and out.

5. The vehicle electrical system according to claim 4 , wherein the at least one component of the vehicle electrical system has a structural element of the housing taking up the component(s) of the vehicle electrical system, in which the temperature-control fluid can be introduced directly surrounding at least some of the structural elements.

6. The vehicle electrical system according to claim 5 , wherein some of the structural elements are disposed in a housing section separated from a through-flow of the temperature-control fluid.

7. The vehicle electrical system according to claim 6 , wherein the temperature-control fluid can be transported by the at least one connection between the energy store, and the components of the vehicle electrical system, or between a distributor unit of the vehicle electrical system and the components of the vehicle electrical system, or between at least two components of the vehicle electrical system.

8. The vehicle electrical system according to claim 7 , wherein a component of the vehicle electrical system is an electrical machine, particularly inclusive of a power converter unit, and a component of the vehicle electrical system is a d.c. voltage transformer, and a component of the vehicle electrical system is a charger.

9. The vehicle electrical system according to claim 8 , wherein it is equipped for supplying a drive device of the motor vehicle and for operating with a vehicle electrical system voltage of at least 60 volts.
