Embodiment Construction

[0027] figure 1 A preferred exemplary embodiment of a battery module 1 is shown with a battery module housing 2 into which six battery cells 3 are inserted. The six battery cells 3 can be cooled by two laterally arranged cooling modules 4 . The battery module housing 2 has an internal rib structure, through which, as figure 2 The six inner first cells 5 are formed as shown. One battery cell 3 can be inserted in each of the six compartments 5 . Furthermore, two outer, lateral recesses 6 are formed by the rib structure, as part of the left and right rail, into which a cooling module 4 can be inserted in each case. Depend on figure 1 It can be seen that the battery cell 3 is positively connected to the first inner compartment 5 . Likewise, the cooling module 4 is positively connected to the outer, lateral recess 6 and thus prevented from falling out. The battery module housing 2 is substantially cuboid-shaped. The projection of the battery module 1 on its bottom surface d...

Abstract

The invention relates to a battery module (1), in particular a battery module used for constructing a vehicle battery. The battery module is provided with a battery module housing (2) and at least one cooling module (4); the battery module housing is internally provided with at least one battery single cell (3); the cooling module can cool at least one battery single cell (3), wherein the battery module housing (2) is provided with an internal fin structure; the fin structure forms at least one internal first grid (5); at least one battery single cell (3) can be inserted into the grid. Accordingly, the fin structure forms at least one external side groove (6) or at least one internal second grid (7), and at least one cooling module (4) can be inserted into the at least one groove (6) or at least one internal second grid (7).

Description

technical field [0001] The invention relates to a battery module with liquid cooling. Background technique [0002] There is an increasing demand for energy storage systems which are widely used not only in stationary applications but also in mobile applications. Relevant examples for stationary storage include emergency back-up power systems (Notstromsysteme) and temporary storage for electrical energy in wind energy installations or photovoltaic installations, and as examples for mobile use motor vehicles including electric vehicles and hybrid vehicles industry. [0003] In this case, the electrical energy store comprises, for example, a plurality of rechargeable storage elements which are designed in the form of batteries or battery systems and which have storage cells designed as battery cells. [0004] The assembly of the battery system is achieved through the electrical connection of multiple battery cells or multiple battery modules, that is, the assembly of the bat...
