Embodiment Construction

[0035] figure 1 The illustrated battery 10 for a vehicle is designed, for example, as a lithium-ion battery. The battery 10 has a plurality of battery cells 12 which are electrically insulated from one another by separators 14 made of plastic, also called separators (see Figure 6 ). The aforementioned prismatic battery cells 12 form a stack.

[0036] The separators 14 connected to each other by an adhesive constitute the side walls 16 and the bottom plate 18 of the casing of the battery 10 (see figure 2 ), in which a stack of battery cells 12 is accommodated. In the area of ​​the housing floor 18 formed by the partition 14, two channels 20 are formed by the partition 14 (see figure 2 ), which accommodates the two profile parts 22, 24 of the cooling device (see figure 1 ).

[0037] The profile parts 22, 24 are designed as flat tubes through which the coolant can flow, and in the flat tubes, cooling fins 26 form a plurality of cooling passages parallel to each other (se...

Abstract

The invention relates to a battery (10) for a vehicle. The battery has: a plurality of battery cells (12) arranged in a housing (16, 18, 20) of the battery (10); and cooling means (22, 24) for removing heat from the battery cells (12) ). A material (32) is inserted between the housing (20) and the cooling device (22, 24), the material occupying a first volume in a base state and an increased volume in an expanded state compared to the first volume. The cooling device ( 22 , 24 ) is pressed against the battery cell ( 12 ) by the material ( 32 ) converted into its expanded state. Furthermore, the invention relates to a method for producing such a battery ( 10 ).

Description

technical field [0001] The invention relates to a battery for a vehicle, in which a plurality of battery cells are arranged in a battery housing. The battery has a cooling device for removing heat from the battery cells. The interspace provided between the housing and the cooling device is filled with a material which occupies a first volume in the base state and an increased volume in the expanded state compared to the first volume. The cooling device squeezes the battery cells by the material transitioning into its expanded state. The invention also relates to a method for producing such a battery. Background technique [0002] DE 10 2007 010 745 A1 describes a battery for a vehicle having a plurality of battery cells arranged in a battery housing. A heat-conducting plate with cooling channels is provided on the top of the battery cell for the heat-conducting medium. A heat-conducting foam, for example polyurethane foam, is arranged between the battery cell connector a...
