[0001] The present invention relates to a charge-discharge inspection system and method for a battery module, and to an inspection system and method capable of stably and efficiently performing charge-discharge inspection of a battery module.

[0002] This application claims the benefit of priority based on Korean Patent Application No. 10-2022-0054492 filed on May 3, 2022, and all contents disclosed in the corresponding Korean patent application are incorporated herein by reference.

Background Art

[0003] Generally, a battery module is provided with a number of electric wires electrically connected to a secondary battery. These electric wires are usually provided in the form of a wire harness including connectors.

[0004] Here, the connector can make an electrical connection with an external device so as to provide the electrical energy generated in the battery module to the external device, and can also be electrically connected to a charge-discharge inspection device during the manufacturing process of the battery module in order to sense characteristics of the secondary battery such as charge and discharge of the battery module.

[0005] Currently, in a charge-discharge inspection system for a battery module, an operator manually connects the battery module and a charge-discharge inspection unit using a wire harness part to perform an inspection process. For this reason, problems have occurred in that the wire harness part moves during the inspection process and a lot of time is required for the inspection process by manual operation.

[0006] Also, after a coupling process of forming a wire harness and connecting it to a battery module is performed, the battery module is transferred to a subsequent inspection process. At this time, there is also a risk that the wire harness may be damaged due to the flow of the wire harness.

[0007] Therefore, there is a need for a charge and discharge inspection system for a battery module to solve such problems.

Modes for Carrying Out the Invention

[0032] Hereinafter, a charge and discharge inspection system for a battery module of the present application will be described with reference to the attached drawings. The attached drawings are exemplary and the charge and discharge inspection system for a battery module of the present application is not limited to the attached drawings.

[0033] FIG. 1 is a drawing exemplarily showing a charge and discharge inspection system for a battery module according to one embodiment of the present application.

[0034] As shown in FIG. 1, the charge and discharge inspection system for a battery module of the present application may include a fixing portion 200 and a charge and discharge inspection portion 500.

[0035] The fixing part 200 is configured to support the battery module 100, and preferably can be provided to support the battery module 100 not only in the inspection process for charge and discharge inspection but also in previous processes. That is, in the coupling process of connecting the first wire harness part 300 to the battery module 100, the fixing part 200 supports the battery module 100, and the fixing part 200 can be provided to transfer the battery module 100 in subsequent inspection processes.

[0036] Different from a general transfer pallet for manufacturing secondary batteries, the fixing part 200 can perform the role of fixing not only the transfer / support of the battery module 100 but also the first wire harness part 300. That is, one end is connected to the battery module 100, and the other end is the first wire harness part 300 formed as a free end, and the fixing part 200 can be connected to the other end to perform the role of fixing the entire first wire harness part 300.

[0037] The battery module 100 may include a terminal block 110 provided on a first side surface and an insertion part 120 provided on a second side surface facing the first side surface. That is, as an example, the battery module is formed in the shape of a rectangular parallelepiped, and the terminal block 110 and the insertion part 120 may be provided on the first side surface and the second side surface provided at both ends in the length direction.

[0038] The battery module 100 is a battery assembly in which a certain number of battery cells are bundled to protect them from external impacts, heat, vibration, etc. and placed in a frame, and includes the terminal block 110 and the insertion part 120 described above.

[0039] The terminal block 110 is a part to which a current application part for applying current to the battery module 100 is electrically connected, and is provided on the first side surface of the battery module 100. By applying current to the battery module 100 through the terminal block 110, charge and discharge of the battery module 100 can be performed. In this specification, the "first side surface" means any one side surface.

[0040] FIG. 2 is a drawing exemplarily showing a first side surface of a battery module according to an embodiment of the present application.

[0041] As shown in FIG. 2, the terminal block 110 may consist of a pair of a positive electrode (+) and a negative electrode (-). Through this, the current application unit can make electrical contact with the positive electrode (+) and the negative electrode (-) of the terminal block 110 respectively to apply a current to the battery module 100. Since the terminal block 110 consists of a pair of a positive electrode (+) and a negative electrode (-), a current for performing charging and discharging of the battery module can be applied to the battery module 100 by performing the above-described contact through the current application unit.

[0042] Also, as shown in FIGS. 1 and 3, the insertion part 120 is a part where the first wire harness part 300 is inserted so that the charge / discharge inspection part 500 is electrically connected to the battery module 100, and may be provided on a second side surface facing the first side surface. In this specification, the "second side surface facing the first side surface" means a side surface different from the first side surface provided at a position facing the first side surface.

[0043] In one example, the battery module 100 may include a plurality of battery cells. As used in this specification, the term "plurality" means two or more, and the upper limit is not particularly limited.

[0044] For example, the battery cell may be a secondary battery. Specifically, the secondary battery is a battery that can be charged and discharged for use of electrical energy. For example, the secondary battery may be a lithium secondary battery. The lithium secondary battery may be manufactured by mounting an electrode assembly in which a positive electrode (Cathode), a separator, and a negative electrode (Anode) are laminated in a pouch. The lithium secondary battery can be charged and discharged while the process of lithium ions being inserted (Intercalation) and deinserted (Deintercalation) from the lithium metal oxide of the positive electrode to the negative electrode is repeated.

[0045] The first wire harness portion 300 can be said to be a cable module for connecting the battery module 100 and an external device. That is, it can be said to be a module for electrically connecting the battery module 100 and an external device. The first wire harness portion 300 may be provided so as to be electrically connected to a charge / discharge inspection unit for charge / discharge inspection. That is, in the charge / discharge inspection process, the external device can be said to be a charge / discharge inspection unit.

[0046] The first wire harness portion 300 can include a first connector 310, a second connector 320, and a first connecting portion 330 that connects them.

[0047] The first connector 310 is a connection mechanism for electrically connecting the battery module 100 and the first connecting portion 330, and is connected to one end of the first connecting portion 330 and inserted into the insertion portion 120 of the battery module 100 for connection. In this specification, "one end" means any one end.

[0048] FIG. 3 is a drawing exemplarily shown to explain the process in which a first wire harness is connected to the insertion portion of the battery module according to an embodiment of the present invention. As shown in FIG. 3, the first wire harness portion 300 can be connected to the battery module 100 by connecting the first connector 310 to the insertion portion 120.

[0049] The second connector 320 is a connection mechanism for electrically connecting the fixing portion 200 and the first connecting portion 330, and can be connected to the other end of the first connecting portion 330 and a connection pin 240 disposed through the first fixing member 220 of the fixing portion 200. In this specification, "the other end" means any one end different from one end, that is, the other end.

[0050] The first connecting part 330 is a part that electrically connects the first connector 310 and the second connector 320, and the first connector 310 and the second connector 320 are electrically connected to both ends thereof, respectively. The first connecting part 330 is suppressed from flowing by fixing the first connector 310 and the second connector 320 described above, and automatic charge / discharge inspection through labor saving is possible, and the working time can be shortened through this.

[0051] In one example, the first connecting part 330 can have flexibility. Although having flexibility of the first connecting part 330 may cause a problem that an operator has to manually connect the second connector 320 and the third connector 410, the second connector 320 is fixed by the fixing part 200, specifically the connecting pin 240, and the flow is suppressed, so that automatic charge / discharge inspection through labor saving is possible, and the working time can be shortened through this.

[0052] Generally, in the conventional coupling process, the assembly of the first wire harness part and the connection of the insertion part 120 and the first connector 310 were performed manually. Since the second connector 320 was left as a free end in this coupling process, there was a risk that the entire first wire harness part would flow and the first wire harness part would be damaged during the movement to the subsequent process or during the subsequent process.

[0053] In order to solve such a problem, according to an embodiment of the present invention, a first fixing member 220 to which the second connector 320 of the first wire harness part 300 can be fixedly coupled can be formed on the fixing part 200.

[0054] The fixing part 200 supports the battery module 100 and is configured to electrically connect and fix the first wire harness part 300 and the second wire harness part 400, and may include a support member 210, a first fixing member 220, a second fixing member 230, and a connecting pin 240. The charge and discharge inspection system of the battery module 100 includes the fixing part 200 having the first fixing member 220, so that the flow of the first wire harness part 300 is suppressed and automatic charge and discharge inspection through labor reduction is possible, and the working time can be shortened through this.

[0055] The support member 210 supports the battery module 100. Specifically, it supports the battery module 100 and the first fixing member 220, and is a member for mounting and moving the battery module in the process.

[0056] In one example, the support member 210 may include a first groove (not shown) provided so that the connecting pin 240 passes through and is fixed. By including the first groove described above, the support member 210 can maintain the connecting pin in a fixed state. Thereby, when inspecting the charge and discharge of the battery module 100, the flow of the first wire harness part 300 inserted into the connecting pin is suppressed, and automatic charge and discharge inspection through labor reduction is possible, and the working time can be shortened through this.

[0057] Also, there may be a plurality of the first grooves, and they may be provided at the position where the first fixing member 220 of the support member 210 is arranged. At this time, the number of the plurality of first grooves is not particularly limited as long as it is equal to or more than the number of the plurality of connecting pins 240 described later.

[0058] Further, the size of the first groove, specifically, the diameter of one of the first grooves may be the same as the diameter of one of the connecting pins, and the specific size is not particularly limited. By having the diameter of the first groove be the same as the diameter of the connecting pin 240, the connecting pin 240 is maintained in a state of being inserted and fixed in the first groove, and the flow of the first wire harness portion 300 inserted into the connecting pin 240 during the charge and discharge inspection of the battery module 100 is suppressed, enabling automatic charge and discharge inspection through labor savings, and through this, the working time can be shortened. In this specification, the "diameter of the connecting pin" may mean the diameter of the cross-sectional area inserted into the first groove.

[0059] The first fixing member 220 is a member for fixing the connecting pin 240, and may be disposed above the support member 210 with a separation interval from the battery module 100. By fixing the connecting pin 240 through the first fixing member 220, the flow of the first wire harness portion 300 during the charge and discharge inspection of the battery module 100 is suppressed, enabling automatic charge and discharge inspection through labor savings, and through this, the working time can be shortened.

[0060] In one example, the first fixing member 220 may include a second groove (not shown) provided such that the connecting pin 240 passes through and is fixed. By the first fixing member 220 including the second groove described above, the connecting pin 240 can be maintained in a fixed state. Thereby, the flow of the first wire harness portion 300 inserted into the connecting pin 240 during the charge and discharge inspection of the battery module 100 is suppressed, enabling automatic charge and discharge inspection through labor savings, and through this, the working time can be shortened.

[0061] Further, there may be a plurality of the second grooves, and they may be provided at positions that coincide with the positions where the first grooves of the support member 210 are arranged. At this time, the number of the plurality of second grooves is not particularly limited as long as it is equal to or more than the number of the plurality of connecting pins 240 described later.

[0062] Further, the size of the second groove, specifically the diameter of one second groove, may be the same as the diameter of one connecting pin, and the specific size is not particularly limited. By making the diameter of the second groove the same as the diameter of the connecting pin 240, the connecting pin 240 is maintained in a state of being inserted and fixed in the second groove, and the flow of the first wire harness portion 300 inserted into the connecting pin 240 during the charge and discharge inspection of the battery module 100 is suppressed, enabling automatic charge and discharge inspection through labor reduction, and through this, the working time can be shortened.

[0063] Further, the area where the first fixing member 220 contacts the support member 210 is not particularly limited as long as it is larger than the size of the first groove, specifically the size obtained by adding the areas of the plurality of first grooves.

[0064] The second fixing member 230 is a member for fixing the connecting pin 240 and is disposed below the support member 210. By fixing the connecting pin 240 through the second fixing member 230, the flow of the first wire harness portion 300 during the charge and discharge inspection of the battery module 100 is suppressed, enabling automatic charge and discharge inspection through labor reduction, and through this, the working time can be shortened.

[0065] In one example, the second fixing member 230 may include a third groove (not shown) provided such that the connecting pin 240 passes through and is fixed. By the second fixing member 230 including the third groove described above, the connecting pin 240 can be maintained in a fixed state. As a result, the flow of the first wire harness portion 300 inserted into the connecting pin 240 during the charge and discharge inspection of the battery module 100 is suppressed, enabling automatic charge and discharge inspection through labor reduction, and through this, the working time can be shortened.

[0066] Further, there may be a plurality of the third grooves, and they may be provided at positions that coincide with the positions where the first grooves of the support member 210 are arranged. At this time, the number of the plurality of third grooves is not particularly limited as long as it is equal to or greater than the number of a plurality of connection pins 240 described later.

[0067] Also, the size of the third groove, specifically the diameter of one third groove, may be the same as the diameter of one connection pin, and the specific size is not particularly limited. Since the diameter of the third groove is the same as the diameter of the connection pin 240, the connection pin 240 is maintained in a state of being inserted and fixed in the third groove, and the flow of the first wire harness portion 300 inserted into the connection pin 240 during the charge and discharge inspection of the battery module 100 is suppressed, enabling automatic charge and discharge inspection through labor saving, and through this, the working time can be shortened.

[0068] The area of the second fixing member 230 in contact with the support member 210 is not particularly limited as long as it is larger than the size of the first groove, specifically the sum of the areas of the circles of the plurality of first grooves.

[0069] In one example, the first fixing member 220 and the second fixing member 230 may be laminated in parallel along the thickness direction. Through this, the connection pin 240 can be fixed at a position described later. That is, the first fixing member 220 and the second fixing member may be provided to face each other with the support member 210 sandwiched therebetween. That is, they may be provided vertically in upper and lower positions. At this time, the connection pin 240 is formed in a straight line and penetrates the support member 210, and both ends may be fixedly coupled to the first fixing member 220 and the second fixing member 230, respectively.

[0070] Therefore, it is preferable that the first fixing member 220 and the second fixing member 230 are always fixed to the support member 210 and their positions are also fixed.

[0071] The connecting pin 240 is a member for energizing the first wire harness part 300 and the second wire harness part 400, specifically, the second connector 320 of the first wire harness part 300 and the third connector 410 of the second wire harness part 400, and is arranged to penetrate through the first fixing member 220, the support member 210, and the second fixing member 230 in this order. By including the connecting pin 240, the fixing part 200 can suppress the flow of the first wire harness part 300, enabling automatic charge and discharge inspection through labor reduction, thereby shortening the working time.

[0072] In one example, the connecting pin 240 extends in the stacking direction of the first fixing member 220, the support member 210, and the second fixing member 230, and the extended length l of the connecting pin 240 may be greater than the total thickness t of the first fixing member 220, the support member 210, and the second fixing member 230. That is, the connecting pin 240 can have a form of a pin with a straight extended length. Since the length l in the length direction of the connecting pin 240 is greater than the total thickness t of the first fixing member 220, the support member 210, and the second fixing member 230, it can penetrate through the first fixing member 220, the support member 210, and the second fixing member 230 and be inserted into the second connector 320 and the third connector 410 respectively. Thereby, the flow of the first wire harness part 300 is suppressed, enabling automatic charge and discharge inspection through labor reduction, and the working time can be shortened through this. In this specification, the term "thickness" means the length in the height direction. The term "extends in the length direction" in this specification means a form in which the connecting pin is formed long along the length direction.

[0073] Also, there may be a plurality of the connecting pins 240, and the upper limit is not particularly limited.

[0074] For the charge and discharge inspection, the battery module 100 must be electrically connected to the charge and discharge inspection part 500. Conventionally, such connection was performed manually.

[0075] According to this embodiment, the charge and discharge inspection unit 500 can be provided to be connected to the second wire harness unit 400. The second wire harness unit 400 can be connected to the second fixing member 230.

[0076] The second wire harness unit 400 is a cable for electrically connecting between the connection pin 240 of the fixing unit 200 and the charge and discharge inspection unit 500, and can include the third connector 410, the position adjustment unit 420, and the second connection unit 430 described above.

[0077] The third connector 410 is a connection mechanism for electrically connecting the connection pin 240 disposed through the second fixing member 230 and the second connection unit 430, and is connected to one end of the second connection unit 430 and connected to the connection pin 240 disposed through the second fixing member 230 of the fixing unit 200.

[0078] The position adjustment unit 420 is a part for adjusting the position of the third connector 410 through reciprocating motion, supports the third connector 410, and moves the third connector 410 toward the connection pin 240 disposed through the second fixing member 230. The position adjustment unit 420 can insert or separate the third connector 410 into or from the connection pin 240 disposed through the second fixing member 230 through the above-described driving. For example, a cylinder can be used in the position adjustment unit. That is, through the driving of the position adjustment unit 420, the electrical connection between the charge and discharge inspection unit 500 and the support member 210 can be automatically performed. Also, the electrical connection between the support member 210 and the battery module 100 can be performed in a previous process, that is, the coupling process. Therefore, by only performing the automatic connection between the charge and discharge inspection unit 500 and the support member 210 in the charge and discharge inspection process, as a result, the electrical connection between the charge and discharge inspection unit 500 and the battery module 100 can be effectively and stably performed.

[0079] The second connecting part 430 is a part that connects the third connector 410 and the charge and discharge inspection part 500. One end passes through the position adjusting part 420 and is connected to the third connector 410, and the other end is connected to the charge and discharge inspection part 500.

[0080] In one example, the second connecting part 430 can have flexibility. Although having flexibility in the second connecting part 430 may lead to the unreasonableness that an operator has to manually connect the third connector 410 and the charge and discharge inspection part 500, the third connector 410 is fixed by the fixing part 200, specifically the connecting pin 240, to suppress fluidity, enabling automatic charge and discharge inspection through labor reduction, thereby shortening the working time.

[0081] The charge and discharge inspection part 500 is an inspection device for confirming the charging and discharging performance of the battery module during the activation process when manufacturing the battery module, and is electrically connected to the second wire harness part 400, specifically the second connecting part 430. Through this, the fluidity of the first wire harness part 300 is suppressed, enabling automatic charge and discharge inspection through labor reduction, and shortening the working time.

[0082] In one example, the charge and discharge inspection part 500 can be electrically connected to the insertion part 120 of the battery module 100 to perform charging or discharging. Specifically, the charge and discharge inspection part 500 can be electrically connected to the insertion part 120 of the battery module 100 through the first wire harness part 300, the connecting pin 240 of the fixing part 200, and the second wire harness part 400. Through this, the fluidity of the first wire harness part 300 is suppressed, enabling automatic charge and discharge inspection through labor reduction, and shortening the working time.

[0083] According to this embodiment, the current application unit 600 can be provided separately from the charge and discharge inspection unit 500. The current application unit 600 is configured to apply a current to the battery module 100 and can be provided to contact the terminal block 110. That is, in the charge and discharge inspection process, the current application unit 600 controls the application of the current to induce the charge and discharge of the battery module, and the charge and discharge inspection unit 500 can inspect the normality of the battery module through the changes in the voltage and current values during charge and discharge, insulation resistance and withstand voltage inspection, and battery temperature monitoring, etc.

[0084] In one example, the current application unit 600 can be electrically connected to the terminal block of the battery module 100 to apply a current. FIG. 5 is a drawing exemplarily shown to explain the process of contacting the current application unit to the terminal block according to an embodiment of the present invention.

[0085] As shown in FIG. 5, the current application unit 600 includes two probes 610, and by contacting each probe 610 with the positive (+) and negative (-) electrodes of the terminal block 110 respectively and being electrically connected, a current for performing the charge or discharge of the battery module 100 can be applied. Through this, the normality of the charge for applying a current to the battery module 100 and the discharge for discharging the current can be confirmed through the charge and discharge inspection unit.

[0086] On the other hand, in an embodiment of the present invention, the position of the second fixing member 230 in the fixing unit 200 is fixed. And the position of the second fixing member 230 is also fixed during the coupling of the second fixing member 230 and the second wire harness unit 400. Therefore, the coupling and decoupling of the second fixing member 230 and the second wire harness unit 400, in other words, the connection between the charge and discharge inspection unit 500 and the battery module 100 in the inspection process can be automatically performed.

[0087] On the one hand, in one embodiment of the present invention, the battery module 100 can be stably mounted on the support member 210 by its own weight. The electrodes formed on the terminal block of the battery module 100 can be exposed at the top. Therefore, the probe 610 of the current application unit 600 can be automatically connected to or disconnected from the electrode. This is because a mechanical coupling such as shape matching is not required for the electrical connection between the probe and the electrode, since the electrical connection between the two is sufficient when the probe 610 moves to contact the electrode above the electrode. Therefore, the electrical connection between the current application unit 600 and the battery module 100 can also be automatically performed within the inspection process.

[0088] That is, according to this embodiment, a stable and efficient charge-discharge inspection can be automatically performed without the need for an operator to manually proceed with the inspection in the charge-discharge inspection process.
