Comme le montre la figure 1, dans un mode particulier de réalisation, un ensemble de batterie conforme à la présente invention comporte six batteries de puissance désignées sur le dessin par la référence 12. Ces batteries sont destinées à être utilisées comme batteries de traction, par exemple dans un véhicule automobile hybride. La configuration avec six batteries est décrite à titre d'exemple nullement limitatif. L'ensemble de batterie comporte au moins une batterie mais peut en comporter plus que six. For the same purpose, the present invention also provides a hybrid motor vehicle, remarkable in that it comprises a battery assembly as briefly described above. Other aspects and advantages of the invention will appear on reading the following description of particular embodiments, given by way of non-limiting examples and with reference to the accompanying drawings, in which: FIG. 1 is an exploded schematic perspective view of a battery assembly according to the present invention, in a particular embodiment; and FIG. 2 is a simplified cross-sectional schematic view of the battery assembly of FIG. 1. As shown in FIG. 1, in a particular embodiment, a battery pack according to the present invention comprises six batteries. The batteries are intended to be used as traction batteries, for example in a hybrid motor vehicle. The configuration with six batteries is described by way of non-limiting example. The battery pack has at least one battery but may have more than six.

L'ensemble de batterie comporte également un bac de réception 10, par exemple de forme sensiblement parallélépipédique, dans lequel sont logées les batteries 12, comme le montre également la figure 2. The battery assembly also comprises a receiving tray 10, for example of substantially parallelepipedal shape, in which are housed the batteries 12, as also shown in Figure 2.

Le bac de réception 10 présente avantageusement sur au moins deux bords opposés des rebords plats dotés d'une pluralité d'orifices de fixation tels que des trous taraudés. Dans le mode particulier de réalisation illustré sur la figure 1, les six batteries sont maintenues dans le bac de réception deux à deux par trois brides 16 qui viennent recouvrir partiellement les batteries 12. En variante, les brides 16 peuvent recouvrir intégralement les batteries 12. Dans une autre variante, on peut aussi prévoir des brides 16 qui maintiennent les batteries quatre à quatre, voire une plaque unique remplaçant les brides et recouvrant toutes les batteries. Chaque bride 16 est en forme de U et présente un rebord plat sur chacune de ses deux extrémités opposées situées de part et d'autre des batteries. Chaque rebord est doté d'une pluralité d'orifices de fixation tels que des trous taraudés, de façon que le rebord de chaque bride 16 puisse être assemblé à un rebord du bac de réception 10, par exemple en insérant des vis dans les trous taraudés des brides 16 et du bac de réception 10. Conformément à la présente invention, chaque bride 16 présente des éléments de fixation tels que des orifices destinés à recevoir les organes électriques 14 nécessaires au fonctionnement des batteries 12.
