Embodiment Construction

[0026] figure 1Firstly, a vehicle 1 (currently a motor vehicle) is shown with an electric motor 2 as drive motor and with a battery 3 forming a traction battery. According to the exemplary embodiment, it is thus a purely electrically operated motor vehicle 1 . The invention also includes so-called hybrid vehicles, which, in addition to one or more electric motors 2 , also have an internal combustion engine (not shown). The battery 3 has a housing 4 which is formed by a housing bottom 5 , a housing wall 6 and a housing cover 7 . The housing 4 is substantially square in design. Inside the housing 4, arranged and electrically connected together are the image 3 The single-cell module 8 is shown in . The cell module 8 itself is composed of individual battery cells 9 . The cell modules 8 are supported on the housing bottom 5 and fastened there by means of mechanical fastening elements 10 , in particular by means of threaded elements. The cell modules 8 or the battery cells 9 ...

Abstract

The invention proposes, amongst other things, a housing (4') for a battery (3), in particular a high-voltage battery (3), for holding cell modules (8) and/or battery cells (9), at least having a housing base (5) and also a housing wall (6), wherein at least one section of said housing (4') comprises a cast part (12'). The cast part (12') advantageously has a channel structure (14) which is open asseen in cross section and which is formed by at least one elongate groove-like recess (15), wherein the groove-like recess (15) is covered by means of at least one covering element (16) in such a waythat a channel structure (17), which is closed as seen in cross section, is designed to guide a temperature-control means within the channel structure.

Description

technical field [0001] The invention relates to a housing for a battery according to the preamble of patent claim 1 of the invention. The invention according to claim 8 also relates to a vehicle with at least one battery having such a housing. Finally, according to the preamble of patent claim 9, the invention relates to a method for manufacturing the above-mentioned housing. Background technique [0002] Electric or hybrid vehicles are operated by means of rechargeable battery systems, in particular HV battery systems (high voltage battery systems) with eg lithium-ion batteries. During driving operation of the vehicle and during charging phases of such a battery system, heat is introduced into the battery system by electrical power losses in the current-carrying components, which can result in a high thermal load on the battery. By operating the battery at higher cell temperatures, it is known that accelerated aging of the battery cells can be registered, which is accompa...
