Embodiment Construction

[0027] figure 1 and figure 2 An exemplary embodiment of a battery assembly 10 is shown comprising electrical energy battery cells or elements 12 stacked along a stacking axis X-X', where the stacking axis X-X' is assumed to be vertical.

[0028] The battery elements 12 are identical to each other and take the form of rectangular plates. The battery elements 12 are axially stacked relative to each other such that the main faces of two adjacent battery elements face each other. In the example shown, the number of accumulator elements 12 is equal to eleven. Obviously, it is possible to provide a different number of battery elements depending on the electrical energy to be released.

[0029] Each battery cell 12 includes an outer encapsulation 14 within which are disposed a cathode and an anode separated by an electrolyte (not shown). The electrolyte can be, for example, an aprotic electrolyte (in the case of lithium-ion type battery elements), or a membrane-based polymer sep...

Abstract

The invention relates to an accumulator assembly for a battery of an electric vehicle or a hybrid vehicle, provided with a deformable connector support. Said accumulator assembly comprises a plurality of electrical energy accumulator elements (12) that each comprise connecting electrodes (18, 20), assembly means (22, 24, 50, 2, 54) connecting said electrodes, a connector (35) for connecting an external component to the assembly, and a connector support (67). Said support (67) comprises an assembly base (64) carried by the assembly means, and a fixing lug (6) that supports the connector and is formed in such a way as to enable the movement of the connector in relation to the assembly base when an external load is applied to the connector and / or the fixing lug.

Description

technical field [0001] The invention relates to the field of accumulator assemblies for electric or hybrid vehicle batteries, in particular for automobiles. Background technique [0002] The expression "electric vehicle" should be understood to mean a vehicle as defined in UN Regulation No. 100 concerning the type approval of battery-powered electric vehicles. [0003] The invention relates more particularly to an accumulator assembly comprising a plurality of electric energy accumulator elements, each accumulator element comprising connecting electrodes and assembly means joining said electrodes. A battery is formed from one or more battery packs and constitutes the source of electrical energy used to power an electric or hybrid vehicle. [0004] Patent application EP-A1-2 131 414 describes an energy storage device comprising an accumulator assembly formed by a plurality of energy storage cells arranged inside an enclosure and connectors added to the side walls of the encl...
