Definitions
- the battery comprises a casing, attached or integrated into the vehicle, in which the modules are arranged, generally in several rows of modules.
- the cells come in various shapes, generally prismatic or cylindrical.
- the support can advantageously form, at least in a part comprising the threaded cavities, a conductor of electricity of low impedance, preferably a copper or aluminum conductor.
- the first conductive means can then be integrated into the support by being formed by said conductor.
- the present invention also relates to a battery comprising a module or a plurality of battery modules electrically connected together in series and/or in parallel, a first main terminal of a first polarity and a second main terminal of a second polarity and a casing receiving and maintaining the module(s) arranged next to each other, said casing comprising two orifices making the main terminals respectively accessible, characterized in that the or each module consists of a battery module according to the present invention and in that the first main terminal is connected to first conductive means of one of the modules and the second main terminal is connected to second conductive means of the or one of the modules.
- FIG-1 is a partial perspective view of a module according to the present invention, in an embodiment comprising a cooling chamber, with a cell and a fluid connector each screwed into one of the threaded cavities
- FIG.2 is a perspective view of the support shown in [Fig.l] without the connector and the cell
- FIG.7 is a partial perspective view of a battery, according to the present invention, showing a group of two modules shown in [Fig.5], connected together in a parallel arrangement and fluidly connected between them, and two cells of which are not represented to show or visualize the fluid connection between the two modules
- FIG. 8 is a partial perspective view of a battery, according to the present invention, showing a group of six modules shown in [Fig.5] connected together in a parallel arrangement and fluidly connected between them,
- FIG.10 is a partial perspective view of a battery, according to the present invention, showing a group of six modules shown in [Fig.5] connected together in a series arrangement and fluidly connected between them,
- FIG.11 is a partial view of a battery according to the present invention comprising a casing in the open state and receiving the group of modules shown in [Fig.10], [0027] [Fig.12 ] shows the battery shown in [Fig.11] in the closed state of the casing and with its own cooling system.
- electrochemical cell 2 is meant a cell 2 forming a single energy accumulator.
- a cell may for example be a lithium-ion cell.
- each cell 2 is provided with a first terminal 20a of a first polarity, for example positive, and the second end 2b is provided with a second terminal 20b of a second polarity, for example negative.
- first conductive means 1, 10a electrically connect the first terminals 20a to each other and second conductive means 3 electrically connect the second terminals 20b to each other.
- Cells 2 can then be electrically mounted together in parallel in module M.
