Definitions
- TITLE Battery cell block, especially for motor vehicles
- the present invention relates to the field of electrochemical accumulators and in particular metal-ion accumulators.
- the invention relates to a stack of flexible packaging accumulators, commonly called “pouch cells” in English or simply “cells” in the remainder of this application.
- an electrical energy accumulator 1 usually comprises at least one electrochemical cell 2 comprising an electrolyte 3 intercalated between a positive electrode or cathode 4 and a negative electrode or anode 5, a current collector 6 connected to the cathode 4, a current collector 7 connected to the anode 5 and finally, a packaging 8 arranged to contain the electrochemical cell and make it sealed to the outside air and to the electrolyte inside the cell, while being crossed by a part of the current collectors.
- packaging can be flexible or rigid.
- the main advantage of flexible packaging is its lightness. Batteries with the highest energy densities therefore have flexible packaging.
- Figure 2 illustrates this type of flexible packaging 8 which is arranged to insulate and seal the electrochemical cell 2 while being crossed by a portion of two conductive tabs 6, 7.
- the conductive tabs commonly called “tabs” in English, are each arranged on an opposite side of the accumulator 1 and extend in the plane of the electrochemical cell 2, of which they form the electrical poles.
- tabs commonly called “tabs” in English
- the battery or battery pack refers to the electrical energy storage element in its final form, but it is possible to identify several levels of cell grouping.
- a module is a subset of an association of identical cells, allowing a higher level of granularity for systems requiring a large quantity of elementary cells.
- a module is a complex and expensive component, integrating multiple structural, electrical, thermal, etc. functions.
- a battery is the result of associations of modules themselves made up of associations of cells.
- document CN 109428024-B describes a battery module in which flexible accumulators are assembled and connected together by means of fixing elements which clamp folded tabs and electrically connected by welding of a flat-shaped conductive element T.
- module type architectures use welded electrical connections which cannot be dismantled in the event of failure.
- the proposed invention aims to facilitate the replacement of flexible accumulators compatible with a so-called "cell to pack” architecture in English, in which the cells are integrated directly into the battery pack without there being any intermediate grouping of the "module” type as in document CN 109428024-B.
- the expression “block of cells” or simply the term “block” therefore designates a plurality of cells arranged adjacently, which should not be confused with a "module”, of which they do not reproduce all the functions.
- the invention therefore relates to a battery cell block, in particular for a motor vehicle, comprising a plurality flexible accumulators juxtaposed with each other and each comprising two tabs arranged on opposite sides of said accumulator and forming the electrical poles of the accumulator.
- Said block also comprises a plurality of pairs of stacked fastening elements each comprising a first fastening element supporting a first tab of an accumulator, and a second fastening element supporting a second tab of said accumulator, said pair of fastening elements being adapted to maintain in pressure contact said tabs against an adjacent pair of fastening elements and to constitute electrical connections with said tabs.
- Said block also comprises layers comprising an electrically insulating material intended to reduce the vibrations of the accumulators and arranged between each pair of adjacent accumulators.
- Said block further comprises removable fixing means allowing the fixing elements to be assembled in a detachable manner.
- said electrical connections are made by means of metal tabs arranged on said fixing elements and brought into contact with pressure with said tabs by stacking two fixing elements.
- said layers comprise a foam or an adhesive.
- each fixing element is provided with at least one boss arranged on an upper face of said fixing element and a cavity formed in alignment with said boss on a lower face of said fixing element, said cavity having a shape complementary to said boss and being intended to house the boss of an adjacent fixing element when it is stacked.
- the removable fastening means include clipping means and/or screwing means.
- the fixing elements are provided with means for measuring voltage and/or temperature.
- the fixing elements are provided with means for pressurizing the metal legs and tabs.
- said block is provided with electrical connection means which pass through the fixing elements inside sheaths arranged in said fixing elements.
- the invention also relates to an electric battery comprising a plurality of blocks as described above, said blocks being associated in series and/or in parallel.
- the invention also relates to a motor vehicle equipped with a battery as described above.

- FIG 2 is a perspective view of a prismatic format lithium-ion accumulator with its flexible packaging according to the state of the art
- FIG 3 a front sectional view of a battery pack according to the invention
- FIG 4] and [Fig 5] are left and right views respectively of the battery pack shown in [Fig 3];
- FIG 6 is a front view of a fixing element according to the invention.
- FIG 7 a front view of a fixing element provided with pressurizing means according to the invention.
- FIG 8 illustrates electrical connection means according to the invention. Detailed description of at least one embodiment
- the invention applies to any metal-ion accumulator or more generally to any electrochemical accumulator.
- a battery pack according to the invention may be on-board or stationary.
- the fields of electric and hybrid transportation and grid-connected storage systems may be envisaged within the scope of the invention.
- Figures 1 and 2 already commented on in the preamble, relate to examples of lithium-ion accumulators and flexible packaging according to the state of the art.
- the accumulators 1 are of prismatic format with flexible packaging 8, usually called “pouch”.
- Figure 3 is a front sectional view of a battery pack 10 according to the invention.
- Figure 4 and Figure 5 are respectively left and right views of the battery pack 10 illustrated in Figure 3.
- the battery block 10 comprises several juxtaposed electric energy accumulators 1 separated from each other by layers 11 which are intended to reduce the vibrations of said accumulators 1.
- Each accumulator 1 comprises at least one electrochemical cell comprising an electrolyte intercalated between a cathode and an anode, a current collector connected to the cathode, a current collector connected to the anode and a packaging.
- the layers 1 1 are intended to provide support in the direction perpendicular to the plane of the cells to improve the mechanical support of the accumulators and promote a good distribution of the compressive forces between the accumulators.
- the layers 1 1 comprise an electrically insulating material in order to reduce the leakage currents that can be generated by the potential difference of the accumulators.
- layers 1 1 may include a foam or an adhesive.
- such a layer 11 is also arranged between an accumulator 1 and a support surface 12 on which the block 10 is fixed.
- the block 10 comprises a plurality of stacked pairs of fixing elements 13 arranged on either side of the accumulators 1.
- the invention also covers the case where the accumulators are juxtaposed in a horizontal direction.
- the support surface 12 is vertical and the stacking of the fixing elements 13 is horizontal.
- Each pair of fixing elements comprises a first 14 and a second 16 fixing elements each respectively supporting a first 15 and a second 17 tabs of an accumulator.
- the pairs of fixing elements are intended to urge said tabs 15, 17 against an adjacent pair of fixing elements. It is therefore necessary to have three pairs of fixing elements to fix two cells and to add a pair of fixing elements to fix each additional cell.
- the pairs of fixing elements are also intended to constitute electrical connections with said tabs.
- Said electrical connections are made by means of metal tabs 18 arranged on said fixing elements 13 and brought into contact with pressure with said tabs 15, 17 by stacking two fixing elements 13.
- the accumulators can be electrically connected in series and/or in parallel in a block 10 according to the invention.
- the electrical series and/or parallel assembly depends on the orientation of the accumulators and the arrangement of the metal legs 18. It is understood that the arrangement of the metal legs 18 may be different from that illustrated in Figures 3 to 5, depending on the intended assembly.
- the battery pack 10 is provided with electrical connection means 21 which pass through the fixing elements inside sheaths 22 arranged in said fixing elements.
- the electrical connection means 21 serve to raise one of the electrical poles through the stack from an end close to the support surface
- the electrical connection means 21 are distinct from the metal tabs 18.
- the fixing elements 13 are provided with removable fixing means allowing the elements 13 to be assembled together in a detachable manner.
- the removable fixing means comprise clipping means and/or screwing means 19, 20.
- the assembly of the elements 13 is carried out by tightening screws 19, 20 which pass through the stack of fixing elements 13 and which are anchored in the support surface 12.
- screws 19, 20 which pass through the stack of fixing elements 13 and which are anchored in the support surface 12.
- the boss 23 is connected to the cavity 25 by a threaded cylindrical channel 27 intended to collaborate with the screws 19, 20 (figure 6).
- FIG. 6 is a front view of a fastening element 13.
- the fastening element 13 comprises at least one boss 23 disposed on an upper face 24 of said fastening element.
- the 13 comprises a cavity 25 formed in alignment with said boss 23 on a lower face 26 of said fixing element.
- the cavity 25 has a shape complementary to the boss 23 and is intended to house the boss 23 of an adjacent fixing element 13 during its stacking. The presence of the bosses 23 and the associated cavities 25 tend to facilitate the relative positioning of the fixing elements 13.
- the assembly of the fixing elements 13 is carried out by clipping means arranged on the bosses 23 and the cavities 25.
- the bosses 23 are provided with an elastic snap hook facing outwards which snaps into a snap opening provided on an outer edge of the cavities 25 when stacking the elements 13. For disassembly, the snap hooks are pushed inwards from the snap opening.
- Figure 7 is a front view of a fixing element 13 provided with a first 28 and second 29 cavities each arranged respectively on the upper 24 and lower 26 faces of said fixing element.
- the cavities 28, 29 house means 30 for applying pressure to the metal tabs 18 with the tabs 15, 17.
- the means 30 for applying pressure comprise springs which tend to push the ends of the metal tab 18 outwards and aim to increase the contact pressure with the tabs 15, 17. It is possible, depending on the desired configuration, to provide means 30 for applying pressure only in one of the cavities 28, 29.
- the fixing elements 13 are further provided with means 31 for measuring voltage and/or temperature.
- the measuring means 31 comprise an electrical connection 32 which connects the metal tab 18 and a measuring terminal 33 arranged on a lateral face of said fixing element 13.
- the pressure-applying means 30 can be used to increase the contact pressure between the electrical connection means 21 and the tabs 15, 17 (figure 8).
- the block 10 may further comprise covers made of electrically insulating material arranged on the metal legs of the fixing elements, in order to prevent any accidental contact of said metal legs with the exterior.
- the invention aims to improve the mass energy density of such a battery, since the accumulators 1 are arranged directly inside the battery without using a mechanical protection structure of the “module” type for the battery blocks 10.
