Abstract

A vehicle component ( 1 ) is provided for cooling a traction battery ( 101 ) that has at least one battery module ( 102 ) with at least one battery cell ( 103 ). The vehicle component ( 1 ) has a cooling device ( 2 ) with a duct system ( 3 ) through which a cooling medium can flow. The duct system ( 3 ) runs along the battery module ( 102 ) for absorbing heat. The battery module ( 102 ) has a first cooling duct ( 13 ) and a second cooling duct ( 23 ). The cooling device ( 2 ) is suitable and designed for charging the first and second cooling ducts ( 13, 23 ) with the coolant in parallel.

First claim

What is claimed is:

1 . A vehicle component for cooling a traction battery of an at least partially electrically operated vehicle, the traction battery having at least one battery module with at least one battery cell, the vehicle component comprising: at least one cooling device with at least one duct system through which at least one cooling medium can flow, the duct system running at least in sections along the battery module for absorbing heat and including at least one first cooling duct and at least one second cooling duct accommodating a flow of coolant, the first and second cooling ducts being arranged substantially in parallel along at least parts of the battery module.

2 . The vehicle component of claim 1 , wherein the cooling device is configured for charging the first and second cooling ducts with the coolant in opposite flow directions.

3 . The vehicle component of claim 2 , wherein the cooling device comprises at least one pump for conveying the coolant in the duct system.

4 . The vehicle component of claim 2 , wherein the first and second cooling ducts are assigned to at least one module group with at least two battery modules.

5 . The vehicle component of claim 2 , wherein the cooling device comprises a multiplicity of mutually adjacent first and second cooling ducts for cooling a multiplicity of the battery modules.

6 . The vehicle component of claim 5 , wherein a common first inlet and a common first outlet are provided for the first cooling ducts, and a common second inlet and a common second outlet are provided for the second cooling ducts.

7 . The vehicle component of claim 1 , further comprising at least one cooling plate in which the cooling ducts are received at least in sections.

8 . The vehicle component of claim 7 , wherein the cooling ducts run between two opposite sides of the cooling plate, and wherein at least one inlet and/or at least one outlet for the cooling ducts are arranged on the sides of the cooling plate.

9 . The vehicle component of claim 7 , wherein the cooling plate is arranged between at least one protective plate and at least one partition plate, the protective plate being between the cooling plate and a road surface, and the partition plate being between the cooling plate and the battery modules.

10 . The vehicle component of claim 9 , further comprising at least one support element configured to be installed on a vehicle body and receives at least one of the cooling plate, the protective plate, the partition plate and the battery module.

11 . A method for cooling a traction battery of an at least partially electrically operated vehicle, the traction battery having at least one battery module with at least one battery cell, the method comprising charging at least one at least one first cooling duct and at least one second cooling duct with a coolant so that the coolant flows in the first and second coolant ducts are substantially parallel.

12 . The method of claim 11 , wherein the first and the second cooling ducts are charged with the coolant in opposite flow directions.
