- the interconference block nexion (II) is then sliding between the guides as well as the adjoining blocks (Bl, B2).
- the guides incorporate arrival (AR1) and output (SOI) paths of each cooling module in the direction of the stack on the side of the adjacent modules and interconnect blocks.
- the sizing of the guides is such that flows (AR12, SO21) of cooling liquid between two consecutive cooling modules (R1, R2) are assured without discontinuity between them (in a sealed manner by the use of auto-type connectors -opturant) while remaining at least equal to the thickness of an adjoining module and an interconnection block.
- a circuit with a single inlet and a single coolant outlet can thus be sufficient to channel the flow of liquid along all the stacked cooling modules.
- a flow stop (not shown) is then possible in the (lower) termination of the stack by inserting a specific interface to the application's need on two of the four liquid inlets / outlets in each guide.
- the interconnection block comprises means for gripping at least one cooling element (R1, R2), which ideally makes it possible to place (mechanically) said element on one of the faces of one of the modules (Ml, M2).
- these engagement means are also secured to the guides of the cooling element, thus forming a monoblock.
- the interconnection block (and if necessary the adjoining or terminal block as in FIGS. 4A, 4B) may comprise a circuit with at least one duct for transferring coolant between inlets and outlets of cooling elements (R1, R2).
- a first cooling element (R1) advantageously comprises a circulation circuit (G1, G2) for cooling fluid encapsulating the interconnection block (II) in a peripheral manner so as to ensure circulation of said liquid with a second cooling element (R2).
- This structure combines assembly or easy disassembly and ensures a stable assembly mechanically and electrically.
- the interconnection block (II), the cooling element (R1), the terminal block (B1) and the guides (G1, G2) form a sealed connection protected from the environment, ideally by means of self-sealing connectors.
- a terminal block (B1) and an interconnection block (II) thus form a vertical or horizontal stack of thickness at least equal to a thickness of the module (M1) of means of storage and, if present, the cooling element (Rl) disposed on one of the assembly faces of the storage means module.
- 5A, 5B represent respectively an interconnection block (12) and a parallel assembly system of two modules (Ml, M2) assembled in a juxtaposed manner (in FIG. variant or even in addition to the stack) according to the invention.
- the interconnection block (12) comprises four anchoring points (CD1, CD2, CD3, CD4), a pair of which is plugged into one of the pairs of the terminal block at the edge of the first module (Ml) and a second pair has been added. insert into one of the pairs of the terminal block at the edge of the second module (M2), each of the borders being able to be contiguous for the juxtaposition.
- the pairs of connected terminals of each module thus form two separate right circuits and can each be provided with a fuse type protection (F1, F2).
- the interconnection block (12) also includes and integrates two plugs (BMS) adapted for transmitting signals from or to an electrical monitoring module (terminal voltage, temperature of a module, etc.). the assembly and / or balancing of the electrical characteristics of the assembled modules.
- FIGS. 6A and 6B respectively represent an interconnection block and a series assembly system of two modules assembled in a juxtaposed manner (alternatively or in addition to the stack) according to the invention.
- 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.
- FIGS 7A, 7B, 7C show an interconnection block (II) and two configurations of the system according to Figure 5B (or similarly Figure 6B) with and without said block.
- a cooling plane element (R1, R2) is respectively disposed on the upper face of each module (M1, M2).
- 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 modules may contain only simpler or basic storage means and therefore more easily interchangeable.
- 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 is adaptable to multiple standards of terminal blocks or storage means.
- 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.
