Embodiment Construction

[0035] Functionally identical components are provided with the same reference symbols in the figures. The figures only show the basic design of the power supply device according to the invention, and the individual components of the device are not necessarily drawn to scale.

[0036] Figures 1 to 4 A device 1 according to the invention for powering a motor vehicle, in particular a passenger car or a motorcycle, is shown in a schematic cross-sectional view. The power supply device 1 comprises a battery arrangement 10 with a certain number of batteries and / or double-layer capacitors 11-1, 11-2, 12-1, 12-2. To simplify the description below, only cells or batteries are referred to. However, it is not restricted thereto, rather the battery or the battery pack can also be replaced by a double layer capacitor or a double layer capacitor pack.

[0037] exist figure 1 In the first exemplary embodiment of FIG. 2 , two battery packs 11 , 12 are shown, which are arranged one above t...

Abstract

A voltage supply apparatus for a motor vehicle, especially a passenger car, truck or a motorcycle, includes a storage cell arrangement having one or more electrochemical storage cells and / or double layer capacitors that are mounted on top of each other. The storage cell arrangement is releasably connected in a form-fitting way to a heat-conducting cooling device that removes heat from the storage cells and / or double layer capacitors such that at least some of the storage cells and / or double layer capacitors of a respective storage cell group can each be thermally connected with the heat-conducting cooling device.

Description

technical field [0001] The present invention relates to a device for powering a motor vehicle, especially a car, van or motorcycle, comprising a battery structure comprising one or more electrochemical cells and / or double layer capacitors, said cells and / or Or double-layer capacitors are provided overlappingly. Background technique [0002] Electrochemical batteries and / or double layer capacitors can reach very high temperatures during operation, so that cooling is necessary. Cooling of the electrochemical cells is achieved from the outside. If sufficient cooling cannot be guaranteed with sufficient reliability, rapid damage can occur which is not compatible with the service life requirements during the operation of the vehicle. [0003] A similar drive battery pack for electric vehicles, fuel cell vehicles and hybrid vehicles is known from DE 10 2007 021 293 A1, in which one or more shaped elements, called lamellae, start from cooling tubes through which a cooling medium ...
