• the plug-in and juxtaposition are identical to those of FIGS. 5A, 5B.
• the difference lies in the fact that only a couple of connected terminals of each module forms a crossed circuit via the conductive anchoring points (A2, A3), itself protected by a single fuse (Fl).
• the juxtaposition is, however, always maintained and stiffened by means of the four mechanical anchor points (Al, A2, A3, A4) of the interconnection block, two of which are cross-conductive conductors.

• the cooling elements (R1, R2) comprise laterally (in the plane of the terminal block (B12) of the underlying module) each an inlet (AR1, AR2) and an outlet (SO1, SO2) of coolant.
• the interconnection block has an inter-module coolant transfer circuit by means of a conduit (C) connecting an output of a module with an input of the other module.
• the duct (C) comprises according to FIG. 7A an inlet (EI).
• FIG. 7B thus illustrates that, in the inserted position, the interconnection block (II) couples the modules electrically and mechanically and also tightly couples and mechanically secures the two cooling elements.
• the interconnection block may comprise a fuse protection on at least one of its electrical terminals, ideally in the form of a fuse bridge advantageously removable between two of the terminals of the interconnection block. This allows easier maintenance in case of electrical problem (short circuit and fuse change).
• the interconnection block may be provided with a monitoring electronics connected to the assembled modules (Ml, M2) by means of integrated connector plugs such as the plugs (BMS, BMS ') illustrated in FIGS. 5 to 7 but which can be integrated for all other embodiments - or by coding (modulated electric carrier) by means of the terminals at the anchor points.

• the interconnection block may be provided with means for balancing the electrical characteristics of assembled modules.
• the interconnection block has an anchoring point positioning geometry adapted to a stack and / or a juxtaposition of modules assembled linearly or orthogonally. This facilitates the arrangement of the modules in a restricted or angular infrastructure as can be the case in optimized environments such as vehicles.
• the anchoring points of the interconnection block are particularly 4, 5, 6, 7 or 8 depending on whether stacking and / or juxtaposition of the modules is desired and on the geometry of the module terminal blocks.

• the interconnection block may comprise connection means between modules, ideally of the type coaxial or spring blade.
• a storage means module comprises at least one supercapacitor and / or a battery, for example such as for the energy requirements of a railway-type vehicle.
