Definitions
- the invention relates to the field of electric batteries for vehicles. More specifically, the invention relates to the field of the electrical interconnection of the electrical load cells of an electric battery.
- Electric batteries especially in the case of electric vehicles, generally consist of an assembly of electric charge cells, also called accumulators. When they are interconnected, in series or in parallel, these accumulators make it possible to deliver an electric power, for example intended to supply electrically the equipment of the vehicle or its engine.
- connection tapes soldered to each terminal of each cell.
- this solution is not satisfactory, insofar as it requires a large number of welding operations and prevents the battery from being dismantled, for example to replace used cells in the context of a maintenance or reconditioning operation. battery.
- connection elements are generally designed to be elastically deformable, so as to maintain contact with the cells. These connection elements are thus welded or soldered to the electronic card.
- This solution is not satisfactory either, insofar as the electronic card equipped with such connection elements is complex to manufacture. Further, the resiliently deformable spring-type contact members are not able to provide contact for all types of vibrations or shocks. The choice of contact elements can thus prove to be tedious and expensive.
- the invention relates to an electric battery, comprising: a. a plurality of electric charge cells, each cell having end faces located on opposite sides of the cell, each end face being provided with a contact terminal; b. at least a first printed circuit board arranged in line with the end faces located on one of the sides of the cells, the printed circuit board being provided with a plurality of first electrical connection elements, each of the first connection elements electrical being located opposite one of the contact terminals of the cells;
- the invention is characterized in that the first printed circuit board comprises a main portion in which are formed a plurality of notches, each notch defining an elastically deformable tab relative to the main portion, each first connection element electrical being disposed on one of the tabs of the first printed circuit board.
- the term “electric load cell” is understood to mean an elementary device, for example electrochemical, for storing electricity, which can discharge and be charged.
- Each cell can be of lithium type, for example of lithium-ion type or of lithium-polymer type.
- Each cell can for example be of generally cylindrical shape, the contact terminals being provided on each end face delimiting the cylinder.
- printed circuit board is meant a printed circuit board, or PCB (from the English Printed Circuit Board), provided with electrical tracks interconnecting the connection elements, and in particular connected to an output connector so in collecting the electric power stored in each of the electric load cells to this output connector.
- the first printed circuit board could include a battery management circuit (also called BMS, standing for Battery Management System).
- the first printed circuit board is arranged with respect to the cells so that each cell creates a mechanical force on each tab directed towards the outside of the battery, and in which each tab of the first card of printed circuit forms a spring having a return force directed towards the interior of the battery.
- each notch of the first printed circuit board may have a U-shape. The tab defined by each notch is thus connected to the main portion of the first printed circuit board by only one of its edges. If desired, the notches can be made by cutting the main portion of the first printed circuit board, prior to assembly of the battery.
- each first connection element is provided with a bump made of an electrically conductive material coming into contact with the contact terminal of one of the cells.
- This bump can for example be produced by depositing the molten electrically conductive material, for example tin, at an end of an electrical track located on the tongue. This embodiment makes it possible to facilitate contact between the electrical track and the contact terminal in the case where the contact terminal is planar.
- the contact terminal of each cell intended to come into contact with one of the first connection elements protrudes of the end face of the cell.
- the first connection element can be plane.

- the battery can include a single spacer member.
- the spacer is arranged to hold the cells in a matrix arrangement, one beside the other.
- the first connection elements are distributed on the first printed circuit board in an arrangement corresponding to that of the cells.
- the spacer member consists of a single plate having a plurality of primary through passages, each cell being engaged through one of the primary through passages.
- each through passage may have a profile corresponding substantially, in shape and dimensions, to that of the cell that it receives.
- the battery comprises a second printed circuit board arranged in line with the end faces located on the other of the sides of the cells, the second printed circuit board being provided with a plurality of second electrical connection elements , each of the second electrical connection elements being located opposite one of the contact terminals of the cells.
- the second printed circuit board comprises a main portion in which are formed a plurality of notches, each notch defining an elastically deformable tab with respect to the main portion, each second electrical connection element being arranged on one tabs on the second printed circuit board.
- the battery comprises a fixing member arranged to hold the first printed circuit board to the second printed circuit board.
- the fixing member can be arranged to exert a force on each of the first and second printed circuit boards directed towards the interior of the battery. We put thus the printed circuit boards under stress, so that the cells create a mechanical force on the tabs.
- the fixing member may comprise one or more connecting rods fixed to the first printed circuit board, and possibly to the second printed circuit board.
- each printed circuit board has one or more orifices, each connecting rod being intended to be engaged through one of these orifices.
- the fixing member can comprise one or more secondary through passages, each arranged opposite one of the orifices of the first and / or second printed circuit boards, each connecting rod being intended to be engaged. through one of the secondary through passages.
- the fixing member may include a housing to which the first and second printed circuit boards are attached.
- the housing may include protuberances, each arranged facing a zone of the main portion of the first and / or of the second printed circuit boards located in line with the tabs, so as to exercise a force on this first and / or second printed circuit board directed towards the interior of the battery.
- the battery comprises a housing arranged to receive the plurality of cells and the first printed circuit board, the housing comprising a means of assembly to an element of a vehicle, in particular to a chassis of an electric vehicle or to a frame of a bicycle.

Thanks to the spacer plate 3, the cells 2 are held in such a way that each of their contact terminals 23 is opposite one of the electrical connection elements 43 of the printed circuit boards 41 and 42.
- Each printed circuit board 41 and 42 has a main portion 44, in which have been cut notches 45 in the shape of a U.
- Each of the notches 45 defines a tongue 46, connected to the main portion by only one of its edges.
- Each tongue 46 is thus elastically deformable with respect to the main portion 44 and forms a spring having a return force bringing the tongue 46 towards the main portion 44 when a force is exerted on this tongue 46.
- each electrical connection element 43 is formed on one of the tabs 46 of the printed circuit boards 41 and 42, and for this purpose comprises a tin bump 47 disposed at an end of an electrical track s 'extending over this tab 46.
- the battery 1 comprises several connecting rods 5, intended to be inserted between the printed circuit boards 41 and 42, being engaged in secondary through passages 32 of the spacer plate 3, provided between the primary through passages 31.
- Holes 48 are formed in the main portions 44 of the printed circuit boards 41 and 42, between the notches 45 and opposite the primary through passages 31.
- Each connecting rod 5 has a threaded protuberance 51 at each of its ends, intended to be engaged through the holes 48 of the printed circuit boards 41 and 42.
- a washer 61 is inserted into each protuberance 51 and a bolt 62 is assembled to each protuberance 51 to fix each connecting rod 5 to the cards 41 and 42.
- the orientations of the notches 45 provided on either side of the orifices 48 are opposite, so as to allow the washers 61 to be held on the cards 41 and 42, these washers allowing uniform retention.
- the cells 2 are inserted into the primary through passages 31 of the spacer plate 3 and the connecting rods 5 are inserted into the secondary through passages 32.
- the first and second printed circuit boards 41 and 42 are arranged on either side of the assembled cells 2, so that the contact terminals 23 face the connection elements 43.
- the washers 61 are then mounted on the protuberances 51 of the connecting rods and the bolts 62 screwed onto these protuberances 51 so as to constrain the cards 41 and 42 and thus generate a force on the tabs 46 towards the inside of the battery.
- the assembly is arranged in a housing (not shown) which can be mounted, via an assembly means, on the vehicle, for example on the frame of an electrically assisted bicycle. As illustrated in [Fig.
- each of the cells 2 exerts, at its end face upper 21, respectively lower 22, a force on the tongue 46 of the first printed circuit board 41, respectively of the second printed circuit board 42, opposite which it is arranged.
- Each tab 46 is thus elastically deformed by one of the cells 2 by being pushed outwards from the battery 1.
