Embodiment Construction

[0030] Preferred embodiments of the battery module of the present invention are described with reference to the drawings.

[0031] figure 1 Shows a side view of a first embodiment of a battery module according to the invention, in which a battery pack 101 with a battery stack and a cooling element designed as a cooling plate 104 are formed on one of their surfaces by a heat-conducting casting as a heat-conducting layer The material layer 102 is connected to a high voltage insulating layer 105 as a voltage insulating layer. Here, the heat-conducting potting compound layer 102 is glued to the lower surface of the battery pack 101 , which forms the first cooler connection surface 122 , while the high-voltage insulating layer 105 is glued to the upper surface of the cooling plate 104 serving as the cooling surface 124 On the surface. A material-bonded connection is thus achieved between the battery pack 101 and the cooling plate 104 by direct bonding.

Abstract

The invention relates to a battery cell module, in particular for a motor vehicle, and to a method for the production thereof. This comprises: a first battery cell package (101; 301; 401 A) having atleast one battery cell, which has a first cooler connection surface (122; 322; 422) and a cooling element (104; 304; 404) intended for cooling of the first battery cell package (301; 401 A), which cooling element has a first cooling surface (124; 324; 424) facing the first cooler connection surface (122; 322; 422). The battery cell module is characterized in that a first voltage-insulating layer (105; 313; 314; 315; 316; 413; 414; 415) and / or a first thermally conducting layer (102; 317; 318; 417) is or are arranged between the first cooler connection surface (122; 322; 422) and the first cooling surface (124; 324; 424), forming a direct, integral connection of the first cooler connection surface (122; 322; 422) to the first cooling surface (124; 324; 424).

Description

technical field [0001] The invention relates to a battery module of a vehicle energy store with a cooling element and a method for its production. Background technique [0002] Battery modules are installed in electric vehicles and hybrid vehicles. These battery modules include a plurality of batteries that are typically stacked into a battery stack and clamped and held in shape by a frame. The frame includes means for fastening to the housing of the energy store. [0003] Usually the battery modules are provided with a bottom cooling device on a so-called heat conducting plate in order to dissipate the thermal energy so that the battery module does not exceed a defined maximum operating temperature. In this case, cooling can take place by means of a medium or fluid flowing through the cooling element. In particular, a form-fit or non-positive connection is used between the cooling element and the heat-conducting plate of the battery module, the heat-conducting plate bein...
