Embodiment Construction

[0048] figure 1 The battery pack 16 shown in is composed of two battery assemblies 01a and 01b which differ in the number of their battery cell modules 2 and thus in the length of their clamping side parts S . The battery module 2 is fixedly surrounded by the frame arrangement 03a or 03b, so that the battery pack 01a or 01b can be transported easily and reliably for assembly, maintenance and other purposes. The frame devices 03a and 03b are respectively formed by two identical functional side parts 04 and two identical clamping side parts S, wherein the size of the clamping side parts S depends on the size of the battery cell modules 2 in the battery pack 01. Changes in quantity and size.

[0049] The side parts 04 each have an inner side (not shown) and an outer functional side, which are joined circumferentially by longitudinal sides 12 a - c . The side part 04 is equipped on its functional side with three fastening elements 05 a, b and c and has a stiffening element 08 w...

Abstract

The present invention relates to a battery assembly including at least one unit module, for example applied to a hybrid vehicle or an electric vehicle. In order to mount the battery pack (01) stably and from multiple sides, the battery cell modules (2) are enclosed in a frame device (3) and connected to other battery packs (01b to d) and / or the supports (6) are connected. Wherein, the fixing element (5) has multiple functions, so that the battery assembly can be selectively installed on the support (6) or connected in series or in parallel with another battery assembly (01b, 01c). In the series installation of the battery packs (01a, 01b), the fixing elements (05a and b) of the side parts (04) facing each other engage with each other and can thus be fixed together with each other on the support (6) or On the other side part (04) of another battery pack (01c or d). In a battery pack (216) fixed on a support (6) and consisting of a plurality of battery assemblies (01a to d), the functional arrangement of said fixing elements (05a, b or c) is such that adjacent side parts ( 04) Interconnection becomes possible. The invention is used in particular in motor vehicles.

Description

technical field [0001] The present invention relates to a battery assembly including at least one unit module, for example applied to a hybrid vehicle or an electric vehicle. Background technique [0002] DE 10 2010 046 529, not previously published, describes a battery module comprising a frame system consisting of two pressure plates and two side parts. The side parts extend behind the pressure plate and are fixed there in a force-transmitting and / or form-fitting manner. The pressure plate itself is secured to a support by means of screws extending therethrough. This inexpensive frame system is characterized by simple installation and results in a secure fixation of the battery pack in the motor vehicle. [0003] A frame system for a fuel cell is known from US 2005 / 0158606 A1, which is designed as a two-part cage. By locking the two-part spacer, the fuel cell is assembled and can be fastened to the carrier via webs that are fixedly connected to the frame system. [000...
