Problems solved by technology

However, the cooling ducts have to be pressed and / or adhesively bonded to the separator or battery module in a complex and expensive manner
Furthermore, the cooling effect is not optimal since the cooling medium reaches the separators or battery modules only via the walls of the cooling channels and the adhesive film

Embodiment Construction

[0036] To clarify the present invention, figure 1 Firstly, a highly schematic perspective view of a high-voltage battery 1 according to the prior art is shown, which can be used in an electric vehicle or a hybrid vehicle. Said battery, hereinafter referred to as HV battery 1, is constructed from a plurality of battery cells 2 (not shown in more detail in the figures), which can also be combined to form a module and can be arranged in a module housing . The battery cells 2 are mounted on a substantially plate-shaped carrier part 3 . The carrier part 3 can be, for example, a separate partition or the aforementioned module housing and is designed to absorb mechanical forces.

[0037] During operation of an electric or hybrid vehicle, efficient cooling of the battery unit 2 is necessary, which cooling is performed by the cooling arrangement 4 . In this case, the cooling arrangement 4 has cooling lines 5 which can be connected to a coolant supply which is not shown in more detai...

Abstract

A battery arrangement, in particular for a motor vehicle, comprising a plurality of battery cells (2) for storing electrical energy, the battery cells (2) being arranged on a carrier part (3); and the battery The device comprises a cooling arrangement (4) having cooling ducts (5) through which a cooling medium flows. The cooling ducts ( 5 ) are produced at least in sections by an additional application process by applying material layer by layer to the carrier part ( 3 ).

Description

technical field [0001] The invention relates to a battery arrangement, in particular for a motor vehicle, having a plurality of battery cells for storing electrical energy and having a cooling arrangement for cooling the battery cells, the battery cells being arranged on a carrier part ; and the invention relates to a cooling arrangement having cooling ducts through which a cooling medium flows. Furthermore, the invention relates to a method for producing a battery arrangement of this type. Background technique [0002] A battery arrangement of this type is generally used to store electrical energy in a motor vehicle and to supply it to an electric drive for driving the motor vehicle. [0003] It is generally known in the field of battery technology for motor vehicles to cool the battery cells in a traction battery in order to dissipate the large heat generated during traction of the motor vehicle due to high currents and large power outputs. [0004] In traction batteries...
