Abstract

A battery device for an at least partially electrically operated motor vehicle. The battery device includes at least one battery module with a module housing device, which provides at least one receiving compartment for a plurality of battery cells and surrounds same in the manner of a housing. A duct system conducts a temperature control medium for controlling the temperature of the battery cells. At least two cooling ducts of the duct system are integrated here in a housing portion of the module housing device and are deflected and/or brought together and/or separated there.

First claim

What is claimed is:

1. A battery device for an at least partially electrically operated motor vehicle, the battery device comprising:
at least one battery module having at least one module housing device,
the module housing device defining at least one receiving compartment for receiving a plurality of battery cells, the module housing device including at least one duct system for conducting at least one temperature control medium for controlling a temperature of the battery cells, and
two interconnected cooling ducts of the duct system are at least partially integrated in at least one housing portion of the module housing device,
wherein the module housing device comprises at least one housing center part arranged between at least two housing end parts, and wherein the two interconnected cooling ducts are disposed on the housing center part, wherein one of the two interconnected cooling ducts is positioned on a bottom side of the housing center part at a location beneath the receiving compartment, and the other of the two interconnected cooling ducts is positioned on a top side of the housing center part at a location above the receiving compartment, wherein one of the two housing end parts includes three end part ducts, each having a fluid inlet, a fluid outlet and a fluid channel extending between the two interconnected cooling ducts for fluidly connecting the two interconnected cooling ducts, wherein the three end part ducts are disposed in said one of the two housing end parts, and wherein the three end part ducts constitute a supply duct and two return ducts.

2. The battery device as claimed in claim 1 , wherein the housing portion has at least one local recess or at least one shortened web running adjacent one of two cooling ducts comprised by the interconnected cooling ducts for interconnecting the two cooling ducts with one another, and wherein the local recess or the shortened web is arranged locally at one end of the housing center part.

3. The battery device as claimed in claim 2 , wherein the at least one local recess or the at least one shortened web is defined in a single wall of the module housing device.

4. The battery device as claimed in claim 1 , wherein the housing center part is at least partially composed of at least one profile component, which is extruded or is produced in a continuous manufacturing process.

5. The battery device as claimed in claim 1 , wherein, in order to seal the housing center part with respect to at least one housing end part or in order to close the interconnected cooling ducts, either (i) the housing center part is screwed or welded or adhesively bonded to or pressed against at least one of the at least two housing end parts, or (ii) wherein at least one plastic or elastic sealing device is arranged between the housing center part and at least one of the at least two housing end parts.

6. The battery device as claimed in claim 1 , wherein the two interconnected cooling ducts run at least in sections in an upper or lower wall of the housing center part.

7. The battery device as claimed in claim 1 , wherein the housing center part is at least partially manufactured from at least one light metal material, and wherein the light metal material is composed of aluminum, aluminum alloy, magnesium or magnesium alloy.

8. The battery device as claimed in claim 1 , wherein the housing center part is at least partially produced from at least one fiber-plastic composite by braiding or pultrusion, or wherein the housing center part is at least partially produced from at least one unreinforced or fiber-reinforced plastic by extrusion.

9. The battery device as claimed in claim 1 , wherein the temperature control medium is water or a water-glycol mixture or an evaporable refrigerant or oil.

10. The battery device as claimed in claim 1 , wherein the battery device is a high-voltage energy accumulator.

11. The battery device as claimed in claim 1 further comprising a reinforcing wall disposed in the module housing device for dividing the at least one receiving compartment into two receiving compartments, wherein the reinforcing wall extends in a same direction as the cooling ducts.

12. The battery device as claimed in claim 11 , wherein the reinforcing wall is aligned with an inlet of the duct system.

13. The battery device as claimed in claim 1 , wherein the supply duct is positioned between and fluidly interconnected to the two return ducts by the interconnected cooling duct in the top side of the housing center part.

14. A motor vehicle with an at least partially electrically operated traction drive, comprising the battery device as claimed in claim 1 , for the energy supply of the traction drive.
