Embodiment Construction

[0036] specific implementation plan

[0037] figure 1 An exploded view of a module 10 according to a particular embodiment of the invention is shown. As shown, the module comprises a plurality of energy storage assemblies 12 arranged in two different levels N1 and N2.

[0038] Each assembly 12 has a generally cylindrical shape and includes a housing mounted body, including side walls extending along the longitudinal axis of the assembly, closed at one end of the side wall by an end wall and at its opposite end. Open your mouth. The cover covers the body at the open end of the body. Thus, the housing comprises a second end wall at the longitudinal end of the side wall. The housing includes a coiled energy storage element comprising a winding of two overlapping electrodes with an interposed separator. Electrolyte is also introduced into the housing for impregnation of the electrodes. Each pole of the winding is electrically connected to an end face of the component, each e...

Abstract

The subject of the invention is an energy storage module (10) comprising a plurality of energy storage assemblies (12) electrically connected to one another, the module comprising an external casing (40) in which are arranged the storage assemblies (12) and at least one heat exchanger (24), the module being characterized in that: the energy storage assemblies (12) are arranged side by side on at least two distinct levels (N1, N2), the or at least one of the heat exchangers (24) being positioned between two adjacent levels so as to be in thermal contact with at least one storage assembly of each of the two adjacent levels on two opposite respective contact faces (26A, 26B) of the exchanger, said or at least one of said exchangers (24) is fixed to the casing (40) of the module at least at a securing wall (28) that is distinct from the contact faces (26A, 26B), the securing walls of the exchanger and of the casing being configured in such a way that the module has a space between the corresponding securing walls (28; 44) of the exchanger and of the casing, at least at a location distinct from a securing site (70).

Description

technical field [0001] The invention relates to an energy storage module comprising a plurality of energy storage components. Background technique [0002] Within the scope of the present invention, "electrical energy storage component" refers to capacitors (i.e. passive systems comprising two electrodes and an insulator), supercapacitors (i.e. systems comprising at least two electrodes, an electrolyte and at least one separator) Or in particular a lithium battery type battery (ie a system comprising at least one anode, at least one cathode and an electrolyte between the anode and cathode). However, the present invention relates more particularly to supercapacitor modules. [0003] Such modules release a large amount of heat due to the internal resistors of the energy storage components, which generate energy losses through the Joule effect. In order to prevent the modules from being damaged due to the excessive temperature of the components, the energy storage modules are...
