APPLICANT
TVS MOTOR COMPANY LIMITED, an Indian company, having its address at “Chaitanya”, No.12 Khader Nawaz Khan Road, Nungambakkam, Chennai 600 006, Tamil Nadu, India.

PREAMBLE TO THE DESCRIPTION
The following specification particularly describes the invention and the manner in which it is to be performed. 
FIELD OF THE INVENTION
[001] The present invention generally relates to a battery pack and more particularly relates to an interconnector of the battery pack.

BACKGROUND OF THE INVENTION
[002] A battery pack includes several battery cells interconnected to each other. The battery pack achieves desired voltage by connecting several battery cells in series, such that each battery cell adds its voltage potential to derive the total terminal voltage. Similarly, the battery pack achieves desired current by connecting several battery cells in parallel. The use of battery packs as an energy source is becoming prevalent in all parts of the world because of advantages offered by stored electrical energy when compared to especially energy generated via fossil fuel powered internal combustion engines. Thus, battery packs are being used to power a variety of electrical and electronic devices for power intensive applications like powering automobiles, work machines and power tools.
[003] Conventionally, a plurality of interconnectors is employed for electrically interconnecting the battery cells of the battery pack in parallel and/or series configurations as the case may be. Each of the interconnector plates is further connected to the battery management system (BMS) to provide optimum operation of the battery pack. In the art, the plurality of interconnectors of the battery pack is composed of nickel. The nickel interconnector is generally designed as a nickel plate adapted to accommodate terminals of the battery cells. However, the nickel interconnector plate offers huge resistance for conduction of current from the battery cells which are connected in parallel to the battery cells which are connected in series. This in turn increases the resistance between the battery cells and leads to non-uniform heating of the battery cells. Heating of the battery cells reduces energy storage capacity and longevity of the battery cells leading to decrease in overall life of the battery pack. Further, interconnectors made from nickel are expensive.
[004] In another art, a solution is to have the nickel plate interconnector superimposed on and welded to a copper plate interconnector configuring a sandwich interconnector. The nickel plate interconnector is welded to the copper plate interconnector such that they are juxtaposed with each other. In this case, the battery cells are connected to the nickel plate interconnector of the sandwich interconnector and current is conducted from the nickel plate interconnector to the copper plate interconnector of the sandwich interconnector. This configuration reduces the resistance during conduction of current between the battery cells due to lower resistance offered by the copper plate interconnector.
[005] Further, the current conductivity is high between the battery cells when the current is conducted laterally between the battery cells from the nickel plate interconnector to the copper plate interconnector of the sandwich interconnector. Thus, current density is highest in a central region of the sandwich interconnector. Therefore, the material of copper and nickel disposed at both longitudinal ends of the sandwich interconnector would be excess material, which in turn increases weight of the battery pack without contributing to efficiency. Further, current conductivity is unnecessarily diverted towards the excess material disposed at the longitudinal ends of the sandwich interconnector and hence reduces overall current inflow in the battery cells.
[006] Thus, there is a need in the art for a battery pack having an interconnector, which addresses at least the aforementioned problems and limitations.

DETAILED DESCRIPTION OF THE INVENTION
[019] Various features and embodiments of the present invention here will be discernible from the following further description thereof, set out hereunder.
[020] The present invention generally relates to a battery pack and more particularly relates to an interconnector of the battery pack. In the ensuing exemplary embodiments, the battery pack is illustrated to have cuboidal shape. However, it is contemplated that the disclosure in the present invention may be applied to any type of battery pack capable of accommodating the present subject matter without defeating the scope of the present invention.
[021] Figure 1 illustrates a top perspective view of an exemplary battery pack 10, in accordance with an embodiment of the present subject matter. Figure 2 illustrates a front elevation view of the battery pack 10 showing a plurality of exemplary interconnectors 30, in accordance with an embodiment of the present subject matter. Figure 3 illustrates a bottom perspective view of the battery pack 10, in accordance with an embodiment of the present subject matter. Referring to Figures 1 through 3, the battery pack 10 includes a casing 20. In an embodiment, the casing 20 is formed of a base wall, one or more side walls and a top wall. In the illustrated embodiment, there are four side walls. The casing 20 encloses a plurality of battery cells 12 (shown in Figure 3) of the battery pack 10. In an embodiment, the plurality of battery cells 12 is oriented to have a longitudinal axis X-X of each of the plurality of battery cells 12 parallel to a face 22 of the battery pack 10. In the illustrated embodiment, the face 22 can be construed as an outer surface of the base wall of the casing 20. However, the casing 20 can be oriented in any manner such that the battery pack 10 need not always rest on the base wall. The battery pack 10 further includes at least one interconnector 30 for electrically interconnecting the plurality of battery cells 12. In the illustrated embodiment, four interconnectors 30 are provided on each of a larger side of the battery pack 10, the larger side being orthogonal to the face 22. Thus, the face 22 is orthogonal to a surface of the at least one interconnector 30 facing the plurality of battery cells 12. The four interconnectors 30 are also orthogonally disposed with respect to the longitudinal axis X-X of each of the plurality of battery cells 12.
[022] Figure 4 illustrates an exploded view of the battery pack 10 showing a plurality of exemplary base plates 40 and connection strips 50 of the plurality of interconnectors 30, in accordance with an embodiment of the present subject matter. The interconnector 30 includes a base plate 40 and one or more connection strips 50. The one or more connection strips 50 are attached to the base plate 40 (shown in Figure 9) so as to enable electrical conduction between the base plate 40 and the one or more connection strips 50. The one or more connection strips 50 and the corresponding base plate 40 are attached together to have the maximum surface contact between both. In an embodiment, the one or more connection strips 50 are attached to the base plate 40 by means of any welding process known in the art, like spot welding. In an embodiment, the one or more connection strips 50 of the at least one interconnector 30 is disposed between the corresponding battery cells 12 electrically connected by the interconnector 30 and the base plate 40 of the interconnector 30, i.e., the connection strips 50 attached to the base plate 40 is sandwiched between the base plate 40 and the plurality of battery cells 12 electrically connected by the connection strips 50. Further, the base plate 40 is formed of a first material and the one or more connection strips 50 is formed of a second material. In an embodiment, the first material forming the base plate 40 consists of copper material, and the second material forming the one or more connection strips 50 consists of nickel material.
[023] Figures 5A, 5B and 5C illustrate a top plan view, a front elevation view and a side elevation view of the base plate 40 of the interconnector 30, in accordance with an embodiment of the present subject matter. Figure 6 illustrates a perspective view of the base plate 40 of the interconnector 30, in accordance with an embodiment of the present subject matter. Referring to Figures 5A through 6, the base plate 40 has at least one column of a plurality of slots 42. In the illustrated embodiment, the base plate 40 has two columns 42A, 42B of the plurality of slots 42. A first column 42A of the at least one column of the plurality of slots 42 of the base plate 40 is disposed closer to a first longitudinal outer peripheral edge 40a of the base plate 40. A second column 42B of the at least one column of the plurality of slots 42 is disposed closer to a second longitudinal outer peripheral edge 40b of the base plate 40. In the illustrated embodiment, the second column 42B of the plurality of slots 42 is adjacent to the first column 42A of the plurality of slots 42. In an embodiment, the base plate 40 has a hole 44 between each of the plurality of slots 42. In the illustrated embodiment, the holes 44 are disposed around a longitudinal centre of the base plate 40, i.e., along either side of an imaginary centre line between the first column 42A of the plurality of slots 42 and second column 42B of the plurality of slots 42.
[024] Figures 7A and 7B illustrate a front elevation view and a side elevation view of the connection strip 50 of the interconnector 30, in accordance with an embodiment of the present subject matter. Figure 8 illustrates a perspective view of the connection strip 50 of the interconnector 30, in accordance with an embodiment of the present subject matter. Referring to Figures 7A through 8, each connection strip 50 has a plurality of leads 52. Further each of the plurality of leads 52 is adapted to establish electrical contact with terminals of the corresponding plurality of battery cells 12 electrically connected by the connection strip 50. Each of the one or more connection strips 50 includes an angular bend 51 corresponding to each of the plurality of leads 52. In the illustrated embodiment shown in Figure 8, the angular bend 51 can be seen at the joint between the connection strip 50 and each of the plurality of leads 52. The angular bend 51 extends towards the plurality of battery cells 12 from the base plate 40. This allows the plurality of leads 52 to be disposed so as to be in contact with the corresponding terminals of the battery cells 12 electrically connected by the connection strip 50 for ease of attachment of terminals of the plurality of battery cells 12 to the plurality of leads 52. This aids in achieving robust electrical contact between the plurality of leads 52 and the corresponding terminals of the plurality of battery cells 12. In an embodiment, the one or more connection strips 50 includes an arcuate bend 54 between each of the plurality of leads 52. Each arcuate bend 54 is attached to the base plate 40 (shown in Figure 9). In another embodiment, each of the arcuate bends 54 between each of the plurality of leads 52 is attached to the base plate 40 by means of any welding process known in the art, like spot welding. The arcuate bends 54 reduce the amount of the second material, i.e., the nickel material required to manufacture the connection strip 50 by about 50%. Further, the arcuate bends 54 of the connection strip 50 provides ease of conductivity of the current flowing from the plurality of battery cells 12 to the base plate 40 directly and consequently increases current conductivity between the plurality of battery cells 12.
[025] Figure 9 illustrates a front elevation view of the interconnector 30, in accordance with an embodiment of the present subject matter. Figures 10A, 10B and 10C illustrate a top plan view, a front elevation view and a side elevation view of the interconnector 30, in accordance with an embodiment of the present subject matter. Figure 11 illustrates a perspective view of the interconnector 30, in accordance with an embodiment of the present subject matter. Figures 10A, 10B, 10C and 11 depict a face of the interconnector 30 which is opposite to the face depicted in Figure 9. Referring to Figures 9 through 11, at least one column of the plurality of slots 42 corresponds to the plurality of leads 52 of at least one of the one or more connection strips 50. The plurality of leads 52 also overlap with the corresponding plurality of slots 42, such that the plurality of leads 52 are exposed at the corresponding plurality of slots 42 from the side of the base plate 40 (shown in Figure 11). In an embodiment, the interconnector 30 includes a first connection strip 50A and a second connection strip 50B of the one or more connection strips 50. The first connection strip 50A is attached to the base plate 40 such that a first set of leads 52a of the first connection strip 50A overlap with the corresponding slots 42 of the first column 42A of the plurality of slots 42 of the base plate 40. In another embodiment, the second connection strip 50B is attached to the first longitudinal outer peripheral edge 40a of the base plate 40, such that a second set of leads 52b of the second connection strip 50B extends outwardly of the base plate 40 to establish electrical contact with terminals of the corresponding battery cells 12 electrically connected by the second connection strip 50B. Thus, while the first set of leads 52a of the first connection strip 50A establishes electrical contact with the corresponding battery cells 12 by overlapping with the first column 42A of the plurality of slots 42 of the base plate 40, the second set of leads 52b of the second connection strip 50B establishes electrical contact with the corresponding battery cells 12 by extending outside the base plate 40 along its first longitudinal outer peripheral edge 40a.
[026] In yet another embodiment, the interconnector 30 includes a third connection strip 50C. The third connection strip 50C is attached to the base plate 40 such that the first set of leads 52a of the third connection strip 50C overlaps with the corresponding slots 42 of a second column 42B of the plurality of slots 42 of the base plate 40. In a further embodiment, the interconnector 30 includes a fourth connection strip 50D of the one or more connection strips 50. The fourth connection strip 50D is attached to the second longitudinal outer peripheral edge 40b of the base plate 40 such that the second set of leads 52b of the fourth connection strip 50D extends outwardly of the base plate 40 to establish electrical contact with terminals of the corresponding battery cells 12 electrically connected by the fourth connection strip 50D. Thus, while the first set of leads 52a of the third connection strip 50C establishes electrical contact with the corresponding battery cells 12 by overlapping with the second column 42B of the plurality of slots 42, the second set of leads 52b of the fourth connection strip 50D establishes electrical contact with the corresponding battery cells 12 by extending outside the base plate 40 along its second longitudinal outer peripheral edge 40b.
[027] In an embodiment, the first connection strip 50A is disposed between the second connection strip 50B and the third connection strip 50C. In another embodiment, the third connection strip 50C is disposed between the first connection strip 50A and the fourth connection strip 50D. In a further embodiment, each arcuate bend 54 of the corresponding connection strip 50 curves around the respective hole 44 of the corresponding base plate 40. In the illustrated embodiment, each arcuate bend 54 of the first connection strip 50A curves around the respective hole 44 disposed between each of the slots 42 of the first column 42A of the plurality of slots 42. And each arcuate bend 54 of the third connection strip 50C curves around the respective hole 44 disposed between each of the slots 42 of the second column 42B of the plurality of slots 42. In an alternate embodiment, the interconnector 30 includes only the first connection strip 50A and third connection strip 50C. In another alternate embodiment, the the interconnector 30 may include only the first connection strip 50A or third connection strip 50C flanked on either side by the second connection strip 50B and the fourth connection strip 50D. These features may be varied depending on design of the battery pack 10.
[028] Advantageously, the present claimed invention provides a battery pack and a composite type interconnector to electrically interconnect a plurality of battery cells of the battery pack. The composite type interconnector disclosed hereinabove solves problems in battery packs existing in the art like an increase in overall weight of the battery pack due to bulky interconnectors made by superimposition of a copper plate on a broad nickel plate, a reduction in current conductivity between the copper plate and the plurality of battery cells due to flow of current through unused material of the nickel plate, etc. The claimed configurations of the battery pack as discussed above are not routine, conventional, or well understood in the art, as the claimed configurations of the battery pack enable the following solutions to the existing problems in conventional technologies. Specifically, the battery pack as claimed eliminates need for complex tools during assembly of the plurality of battery cells and increases ease of assembly in electrically connecting the plurality of battery cells to the interconnectors. The disclosed interconnector design allows for a reduction in weight of the connection strip made of nickel by reducing the amount of nickel being used by half, and in turn reduces the overall weight of the battery pack. Conductivity of electric current from the plurality of battery cells to the base plate made of copper through the connection strips is increased by removal of unused nickel material from the connection strips by employing a series of arcuate bends. The invention further provides a one-way path for current conductivity from the plurality of battery cells to the base plate for uniform current distribution. The disclosed battery pack also reduces ageing and capacity degradation of the plurality of battery cells by preventing non-uniform heating of the battery cells, thereby aiding in prolonging longevity of the battery pack. The battery pack further improves ease of assembly and serviceability and allows for use of common parts thus lowering overall costs. Other advantages include increased durability, better aesthetics, modularity and better ergonomics of the battery pack.
