Embodiment Construction

[0039] Components corresponding to each other are provided with the same reference numerals in all figures.

[0040] figure 1 A flat single-cell galvanic cell 1 is shown in perspective and side view with a housing 2 , which is designed in particular as a metal housing and has extensions 3 for heat dissipation. The single primary cells 1 are designed as bipolar cells each having two half-shells 2.1, 2.2 which are separated by a separator. Other types of single primary cells 1 may also be provided. In the wall of at least one half-shell 2 . 1 , 2 . 2 are arranged four spacers 11 , which are designed, for example, as elevations.

[0041] figure 2 shows the basis figure 1 The single galvanic cell 1 has a U-shaped insert 4 serving as a spacer in the region of the extension 3 .

Abstract

The invention relates to a battery (6) comprising at least one temperature control unit (7) that is configured as a cooling plate, and at least two galvanic individual cells (1), each having a metal housing (2), wherein the metal housing (2) has an extension (3), which can be accommodated at least partially in a respective recess (8) of the temperature control unit (7).

Description

technical field [0001] The invention relates to a battery pack consisting of a plurality of individual cells which, according to the preamble of claim 1 , conduct heat at least indirectly in the region of at least one edge side with a temperature control unit capable of effectively controlling the temperature Contacting is considered to be known here as it is used, for example, in powertrain technology, and here in particular in vehicle technology that supports at least a battery drive. Background technique [0002] Battery packs—especially the so-called high-power nickel-metal hydride or lithium-based battery packs commonly used today to power vehicles such as electric or hybrid vehicles—typically consist of stacked prismatic primary cells (also called cell battery) composition. A plurality of such single primary cells are correspondingly combined into a battery pack. The single primary battery will heat up strongly during operation, so it must be cooled. [0003] In ord...
