Embodiment Construction

[0039] figure 1 A battery arrangement 10 is shown which comprises individual battery cells 12 as battery cells. Such a battery cell 12 can be designed, for example, as a lithium-ion battery cell which supplies electrical energy for an electric drive motor of the vehicle. The battery cells 12 are surrounded by a housing 14 , which, like the battery cells 12 , is circular in cross section. A plurality of cooling fins 18 are formed in one piece with the wall 16 of the housing 14 and protrude radially from the wall 16 around the outer circumference.

[0040] Housing 14 with cooling fins 18 serves as a cooling device for battery cells 12 . The cooling device is arranged in the load path of the vehicle in such a way that the cooling fins 18 deform when forces are applied to the vehicle due to an accident. The load path is in figure 1 Indicated by arrow 20.

[0041] in accordance with figure 1 In the battery arrangement 10 shown, the cooling fins 18 are also used in a targeted ...

Abstract

The invention relates to a vehicle having at least one battery arrangement (10), which comprises at least one battery unit (12) and a cooling device for dissipating heat from the at least one battery unit (12). The cooling device is arranged in a load path (20) of the vehicle in such a way that the cooling device can be deformed in the event of an application of force to the vehicle caused by an accident. For this purpose, the cooling device comprises a plurality of cooling ribs (18) around which cooling air flows during cooling operation of the cooling device.

Description

technical field [0001] The invention relates to a vehicle having at least one battery arrangement comprising at least one battery cell and a cooling / radiation device for dissipating heat from the at least one battery cell. In this case, the cooling device is arranged in the load path of the vehicle in such a way that it can deform when forces are applied to the vehicle as a result of an accident. The cooling device comprises a plurality of cooling fins / radiating fins which are circulated by cooling air during the cooling operation of the cooling device. Background technique [0002] DE 10 2008 024 291 A1 describes a passenger car with a floor, which has cross members and side skirts as well as side members in the passenger compartment area. In the area surrounded by these beams a battery can be arranged for closing the body. The battery also assumes the functions of closing the body and carrying the load. For cooling, the battery can have a cooling body with cooling fins ...
