Description

Technical Field

[0001] This application claims the benefit of priority based on Korean Patent Application No. 10-2022-0070939 filed on June 10, 2022 and Korean Patent Application No. 10-2023-0048466 filed on April 12, 2023, and all the contents disclosed in the documents of the Korean patent applications are incorporated herein by reference in their entirety.

[0002] The present invention relates to a temperature sensing assembly for sensing the temperature of a cell stack and a battery module including the same.

Background Art

[0003] In modern society, as the use of portable devices such as mobile phones, laptops, camcorders, and digital cameras has become common, active development has been carried out in technologies related to fields associated with such mobile devices. In addition, rechargeable secondary batteries are used as power sources for electric vehicles (EVs), hybrid electric vehicles (HEVs), plug-in hybrid electric vehicles (P-HEVs), etc. as a means of solving air pollution caused by existing gasoline vehicles using fossil fuels, etc., and the need for development of secondary batteries is increasing.

[0004] Currently, commercially available secondary batteries include nickel-cadmium batteries, nickel-metal hydride batteries, nickel-zinc batteries, lithium secondary batteries, etc. Among these, lithium secondary batteries have attracted attention because they have almost no memory effect compared to nickel-based secondary batteries, can be freely charged and discharged, have a very low self-discharge rate, and have a high energy density.

[0005] Such lithium secondary batteries mainly use a lithium-based oxide and a carbon material as a positive electrode active material and a negative electrode active material, respectively. A lithium secondary battery includes an electrode assembly in which a positive electrode plate and a negative electrode plate coated with such positive electrode active material and negative electrode active material, respectively, are arranged with a separator interposed therebetween, and an exterior material for hermetically storing the electrode assembly together with an electrolytic solution, that is, a battery case.

[0006] Generally, lithium secondary batteries can be classified into can-type secondary batteries in which the electrode assembly is built into a metal can and pouch-type secondary batteries in which the electrode assembly is built into a pouch made of an aluminum laminate sheet, depending on the shape of the exterior material.

[0007] In the case of secondary batteries used in small devices, 2 to 3 battery cells are arranged. However, in the case of secondary batteries used in medium and large-sized devices such as automobiles, a battery module in which a large number of battery cells are electrically connected is used.

[0008] In such a battery module, a large number of battery cells are connected in series or parallel with each other to form a battery cell stack, thereby improving the capacity and output. Also, one or more battery modules can be mounted together with various control and protection systems such as a BMS (Battery Management System) and a cooling system to form a battery pack.

[0009] On the other hand, when the battery cells included in the battery module are overvoltage, overcurrent, or overheating, the safety and operating efficiency of the battery module become major problems. As an example, when the pressure and temperature of the battery increase, the decomposition reaction of the active material and a number of side reactions proceed, thereby rapidly increasing the temperature of the battery, which also accelerates the reaction between the electrolyte and the electrode. Finally, a thermal runaway phenomenon occurs in which the temperature of the battery rapidly increases, and when the temperature rises above a predetermined level, there is a possibility of ignition of the battery, and there is a possibility that the battery cells and the battery module including them will explode due to the increased internal pressure of the battery.

[0010] Therefore, means for detecting the temperature change of the battery cells are necessary. For this purpose, a temperature sensor such as a thermistor is arranged in the battery module to check and control the operating state in real time or at predetermined intervals. Summary of the Invention Problems to be Solved by the Invention

[0011] One problem to be solved by the present invention is to provide a temperature sensing assembly with improved accuracy and reliability that prevents damage to the temperature sensor, and a battery module including the same.

Means for Solving the Problem

[0012] A temperature sensing assembly according to an embodiment of the present invention may include a substrate, a temperature sensor mounted on the substrate, a bridge coupled to the substrate and having a hole formed therein facing the temperature sensor, and compression members positioned on both sides of the temperature sensor between the bridge and the substrate.

[0013] The bridge may be coupled above the substrate.

[0014] The bridge may include a main body portion to which the substrate is coupled, and an extension portion extending from the main body portion and in contact with the compression member at a predetermined interval from the substrate.

[0015] The hole may be formed in the extension portion.

[0016] The substrate may include a coupling portion coupled to the bridge, and a mounting portion on which the temperature sensor is mounted at a predetermined interval from the bridge.

[0017] An adhesive layer may be provided between the coupling portion and the bridge.

[0018] The substrate may further include an inclined portion that connects the coupling portion and the mounting portion and is formed obliquely with respect to the mounting portion.

[0019] The compression member may be adhered to the bridge and the substrate.

[0020] The hole may not overlap with the compression member in the penetration direction of the hole (it may not overlap).

[0021] The battery module according to an embodiment of the present invention can include a housing, a cell stack including a plurality of battery cells housed in the housing and arranged in parallel with each other, and a temperature sensing assembly that senses the temperature of the cell stack. The temperature sensing assembly can include a substrate located above the cell stack, a temperature sensor mounted on the substrate, a bridge coupled to the substrate and having a hole formed therethrough toward the temperature sensor, and compression members located on both sides of the temperature sensor between the bridge and the substrate.

[0022] The battery module can further include a busbar frame to which a busbar connected to the plurality of battery cells is mounted. The bridge can be rotatably coupled to the busbar frame.

[0023] At least a part of the temperature sensing assembly can be located between an upper plate of the housing and the cell stack.

Advantages of the Invention

[0024] According to a preferred embodiment of the present invention, even if the cell stack expands or pressure is applied to the substrate due to tolerances or the like during the assembly of the battery module, damage to the temperature sensor can be prevented by the compression members, and the substrate can be maintained in a state adjacent to or in close contact with the cell stack. Thereby, the accuracy and reliability of the temperature sensor can be improved.

[0025] Also, since the compression members do not interfere with the temperature sensor and the bridge hole is formed to face the temperature sensor, the temperature sensor can enter the bridge hole even if the compression members are overly crimped. Thereby, damage to the temperature sensor can be prevented.

[0026] In addition, it can include effects that can be easily predicted by those skilled in the art from the configuration according to the preferred embodiment of the present invention.

Modes for Carrying Out the Invention

[0029] Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail so that those having ordinary knowledge in the technical field to which the present invention pertains can easily implement it. However, the present invention can be realized in various different forms and is not limited or restricted by the following embodiments.

[0030] For the purpose of clearly explaining the present invention, detailed descriptions of parts not related to the explanation or of related known technologies that may obscure the gist of the present invention are omitted. When attaching reference numerals to the components of each drawing in this specification, the same or similar reference numerals are attached to the same or similar components throughout the specification.

[0031] Also, the terms and words used in this specification and the claims should not be construed as being limited to their ordinary or dictionary meanings. The inventors should interpret them in accordance with the meaning and concept that conform to the technical idea of the present invention in accordance with the principle that they can appropriately define the concept of the terms in order to explain their invention in the best way.

[0032] FIG. 1 is a perspective view showing the appearance of a battery module according to an embodiment of the present invention, and FIG. 2 is an exploded perspective view of the battery module shown in FIG. 1.

[0033] A battery module 100 according to an embodiment of the present invention can include a cell stack 110 and a housing 120.

[0034] The cell stack 110 can include a plurality of battery cells 111 arranged parallel to each other. The cell stack 110 can be housed in the housing 120.

[0035] A plurality of battery cells 111 can be arranged to face each other in a first direction (for example, a direction parallel to the Y-axis). More specifically, the plurality of battery cells 111 can be stacked on top of each other in the first direction. Also, each battery cell 111 can be arranged to be long in a second direction (for example, a direction parallel to the X-axis) perpendicular to the first direction. The first direction can be a direction parallel to the full width direction of the housing 120, and the second direction can be a direction parallel to the full length direction of the housing 120.

[0036] Each battery cell 111 can be a pouch-type battery cell. The pouch-type battery cell can maximize the number of layers per unit area and increase the energy density of the battery module 100. The battery cell 111 provided in a pouch type can be manufactured by housing an electrode assembly including a positive electrode, a negative electrode, and a separator in a cell case formed by molding a laminate sheet and then heat-sealing the cell case. However, it is obvious that the battery cell 111 does not necessarily have to be provided in a pouch type, and it may be provided in a square, cylindrical, or other various forms as long as the storage capacity required by the device to be mounted later is not achieved.

[0037] Each battery cell 111 may be provided with a pair of electrode leads 112. The pair of electrode leads 112 can protrude in opposite directions to each other and can protrude parallel to the longitudinal direction of the battery cell 111. However, it is not limited to this, and it is also possible for the pair of electrode leads 112 to protrude parallel to each other in the same direction.

[0038] Also, the cell stack 110 may be provided with at least one heat dissipation pad. The heat dissipation pad can be arranged between the plurality of battery cells 111 or can be arranged to cover the outermost battery cell 111.

[0039] The housing 120 can form the appearance of the battery module 100. The housing 120 can be made of a metal material having high strength.

[0040] The structure of the housing 120 can be various. As an example, the housing 120 can be a monoframe. The monoframe can be a metal plate material in which an upper plate 121, a lower plate, and both side plates are integrated. As another example, the housing 120 can have a structure in which a U-shaped frame is coupled to the upper plate 121. The U-shaped frame can be a metal plate material in which a lower plate and side plates are coupled or integrated. In addition, the structure of the housing 120 may be provided with a structure to which an L-shaped frame is coupled, or may be provided with various structures not described in the above examples.

[0041] The housing 120 can have an internal space, and the cell stack 110 can be accommodated in the internal space. More specifically, the housing 120 can include an upper plate 121, a lower plate, and both side plates. Both ends of the housing 120 in the entire length direction can be opened and can be covered by an end plate 140 described later.

[0042] The battery module 100 can further include a bus bar frame 130 and an end plate 140.

[0043] The bus bar frame 130 can be disposed on both sides in the entire length direction of the cell stack 110. At least one bus bar 131 can be mounted on the bus bar frame 130, and each bus bar 131 can be connected to the electrode lead 112 of the battery cell 111. The bus bar 131 can be a configuration for electrically connecting a plurality of battery cells 111 to an external device.

[0044] The end plate 140 can be disposed outside the bus bar frame 130. That is, the bus bar frame 130 can be disposed between the cell stack 110 and the end plate 140.

[0045] The end plate 140 can be coupled to the housing 120. The end plate 140 can cover the open ends of the housing 120. An opening 140h is formed in the end plate 140, and electrical connection of the bus bar 131 can be made through the opening 140h. That is, the bus bar 131 of one battery module 100 can be electrically connected to other battery modules 100 or a BDU (Battery Disconnect Unit) through the opening 140h.

[0046] FIG. 3 is a diagram showing a temperature sensing assembly provided in a battery module according to an embodiment of the present invention, FIG. 4 is an exploded perspective view of the temperature sensing assembly according to an embodiment of the present invention, FIG. 5 is a plan view of the temperature sensing assembly according to an embodiment of the present invention, and FIG. 6 is a schematic diagram for explaining the operation of the temperature sensing assembly according to an embodiment of the present invention.

[0047] The battery module 100 can include a temperature sensing assembly 10 that senses the temperature of the cell stack 110.

[0048] At least a part of the temperature sensing assembly 10 can be located between the upper plate 121 of the housing 120 and the cell stack 110. That is, at least a part of the temperature sensing assembly 10 can be located above the cell stack 110 and below the upper plate 121. The temperature sensing assembly 10 can be pressed or adhered to the cell stack 110 by the upper plate 121 or another configuration located below the upper plate 121.

[0049] The temperature sensing assembly 10 can be coupled to the bus bar frame 130. More specifically, the temperature sensing assembly 10 can be rotatably coupled to the bus bar frame 130. For example, the temperature sensing assembly 10 can be hinged to the bus bar frame 130.

[0050] As a result, the temperature sensing assembly 10 can be reliably adhered to the cell stack 110, and the temperature of the cell stack 110 can be accurately measured.

[0051] The temperature sensing assembly 10 can include a substrate 20, a temperature sensor 40 mounted on the substrate 20, a bridge 30 coupled to the substrate 20 and having a hole 34 formed therein that faces (opposes) the temperature sensor 40, and a compression member 50 disposed between the bridge 30 and the substrate 20.

[0052] The substrate 20 can be located above the cell stack 110. The substrate 20 can be formed generally long in the longitudinal direction of the cell stack 110. The substrate 20 can include a plurality of regions having different inclinations from each other. The substrate 20 can be integrally formed, but is not limited thereto.

[0053] A temperature sensor 40 can be mounted on the substrate 20. The temperature sensor 40 can be an element capable of sensing temperature. The temperature sensor 40 can be fixed on the substrate 20 by soldering.

[0054] The temperature sensor 40 can include a thermistor. A thermistor is a semiconductor element that uses the phenomenon that its resistance value changes according to temperature. A thermistor has the advantages of being small in size and capable of measurement even for rapid temperature changes or fine temperature changes.

[0055] The substrate 20 can be a flexible printed circuit board (FPCB). The substrate 20 can be electrically connected to the temperature sensor 40 and transmit the temperature information measured by the temperature sensor 40 to the outside.

[0056] The temperature information measured by the temperature sensor 40 can be transmitted to other devices outside the battery module 100. For example, the temperature information measured by the temperature sensor 40 can be transmitted to a Battery Management System (BMS) outside the battery module 100 and can be used to control the battery module 100.

[0057] The bridge 30 can be coupled to the upper side of the substrate 20. The bridge 30 has higher rigidity than the substrate 20 and can support the substrate 20.

[0058] The bridge 30 can be formed generally long in the longitudinal direction of the entire cell stack 110. The bridge 30 can include a plurality of regions having different inclination degrees from each other. The bridge 30 can be integrally formed, but is not limited thereto.

[0059] The bridge 30 can be rotatably connected to the bus bar frame 130. More specifically, the bridge 30 can be hinge-coupled to the upper end of the bus bar frame 130 so as to be rotatable with respect to the bus bar frame 130. Since the bridge 30 is coupled to the substrate 20, the bridge 30 can rotate together with the substrate 20. The bridge 30 can rotate about an axis parallel to the stacking direction of the cell stack 110.

[0060] A hole 34 can be formed in the bridge 30 to face the temperature sensor 40 on the substrate 20. Therefore, even if the substrate 20 is deformed toward the bridge 30, the temperature sensor 40 can be inserted into the hole 34. That is, it is possible to prevent the temperature sensor 40 from interfering with the bridge 30.

[0061] The substrate 20 can include a coupling portion 21 that couples to the bridge 30 and a mounting portion 22 on which the temperature sensor 40 is mounted at a predetermined interval from the bridge 30. The substrate 20 can further include an inclined portion 23 that connects the coupling portion 21 and the mounting portion 22 and is formed obliquely with respect to the mounting portion 22.

[0062] The bridge 30 can include a main body portion 31 to which the substrate 20 is coupled, and an extension portion 32 extending from the main body portion 31 and contacting the compression member 50 with a predetermined interval from the substrate 20. The bridge 30 can further include a connection portion 33 rotatably connected to the bus bar frame 130.

[0063] The coupling portion 21 of the substrate 20 can be adhered to the bridge 30, whereby it can be easily coupled to the bridge 30. That is, an adhesive layer 60 may be provided between the coupling portion 21 and the bridge 30.

[0064] The coupling portion 21 can be coupled to the main body portion 31 of the bridge 30. The coupling portion 21 of the substrate 20 can be formed parallel to the main body portion 31 of the bridge 30. Accordingly, the coupling portion 21 and the main body portion 31 can be in close contact and coupled with the adhesive layer 60 interposed therebetween.

[0065] For example, the adhesive layer 60 can be a double-sided tape.

[0066] However, the coupling method between the coupling portion 21 of the substrate 20 and the main body portion 31 of the bridge 30 is not limited thereto.

[0067] The mounting portion 22 of the substrate 20 can have a predetermined interval from the bridge 30. More specifically, the mounting portion 22 can have a predetermined interval from the extension portion 32 of the bridge 30. Due to the interval, the temperature element 40 and the compression member 50 can be disposed between the substrate 20 and the bridge 30.

[0068] The extension portion 32 of the bridge 30 can extend from the main body portion 31. The extension portion 32 and the main body portion 31 can be parallel to each other or formed at different gradients.

[0069] The mounting portion 22 of the substrate 20 can be formed parallel to the extension portion 32 of the bridge 30. Accordingly, the interval can be formed to be constant with respect to the longitudinal direction of the mounting portion 22.

[0070] A temperature sensor 40 can be mounted on the mounting portion 22. The temperature sensor 40 can be fixed on the mounting portion 22 by soldering.

[0071] The temperature sensor 40 can face the hole 34 formed in the bridge 30. More specifically, a hole 34 facing the temperature sensor 40 can be formed in the extension portion 32 of the bridge 30. Thereby, even if the mounting portion 22 of the substrate 20 is deformed toward the extension portion 32 of the bridge 30, the temperature sensor 40 can be inserted into the hole 34. That is, it is possible to prevent the temperature sensor 40 from interfering with the extension portion 32 of the bridge 30.

[0072] The inclined portion 23 of the substrate 20 is located between the coupling portion 21 and the mounting portion 22 and can connect the coupling portion 21 and the mounting portion 22. The inclined portion 23 can be formed integrally with the coupling portion 21 and the mounting portion 22. Due to the inclined portion 23, the coupling portion 21 and the mounting portion 22 can generally form a step. Thereby, the coupling portion 21 can be in close contact with the main body portion 31 of the bridge 30, and the mounting portion 22 can form a predetermined interval from the extension portion 32 of the bridge 30.

[0073] The connecting portion 33 of the bridge 30 can have a shape bent downward in the main body portion 31. The connecting portion 33 can be rotatably connected to the bus bar frame 130.

[0074] The compression member 50 can be disposed between the substrate 20 and the bridge 30. The compression member 50 can be disposed between the mounting portion 22 of the substrate 20 and the extension portion 32 of the bridge 30.

[0075] The compression member 50 can be adhered to the substrate 20 and the bridge 30 respectively. That is, the bottom surface of the compression member 50 can be adhered to the mounting portion 22 of the substrate 20, and the upper surface can be adhered to the extension portion 32 of the bridge 30.

[0076] For example, a lower adhesive layer may be provided between the bottom surface of the compression member 50 and the upper surface of the mounting portion 22, and an upper adhesive layer may be provided between the upper surface of the compression member 50 and the lower surface of the extension portion 32. The lower adhesive layer and the upper adhesive layer can be double-sided tapes.

[0077] Thereby, it is possible to prevent the mounting portion 22 of the substrate 20 and the extension portion 32 of the bridge 30 from being separated or deformed in an unintended direction.

[0078] The compression member 50 can be configured to be compressed when the substrate 20 is deformed toward the bridge 30. The compression member 50 can relieve the deformation of the substrate 20 and prevent the substrate 20 from interfering with the bridge 30. Further, the durability of the temperature sensing assembly 10 can be improved by the compression member 50.

[0079] The compression member 50 can be a compression pad whose material itself has an elastic force and is compressed and deformed. In this case, the material of the compression member 50 is not limited and can have a material that is elastically deformed by a preset external force. For example, the compression member 50 can have a material that is elastically deformed such as a sponge or polyurethane foam, and can be compressed between the bridge 30 and the substrate 20.

[0080] However, it is not limited to this, and the compression member 50 can also be configured to exhibit an elastic force depending on its shape, such as a spring.

[0081] The compression member 50 can be located on both sides of the temperature sensor 40. That is, a part of the compression member 50 can be located on one side of the temperature sensor 40, and another part of the compression member 50 can be located on the other side of the temperature sensor 40.

[0082] For example, the compression member 50 can include a first compression member 50 disposed on one side of the temperature sensor 40 and a second compression member 50 disposed on the other side of the temperature sensor 40.

[0083] As a result, the compression member 50 does not interfere with the temperature sensor 40, and when the compression member 50 is compressed, it is possible to prevent pressure from being applied to the temperature sensor 40. More specifically, even when the cell laminate 110 expands or pressure is applied to the substrate 20 due to tolerances or the like during the assembly of the battery module 100, it is possible to prevent damage to the temperature sensor 40 by the compression member 50, and the substrate 20 can be maintained in a state adjacent to or in close contact with the cell laminate 110. Thereby, the accuracy and reliability of the temperature sensor 40 can be improved.

[0084] The hole 34 formed in the bridge 30 can be non-overlapping with the compression member 50 in the penetrating direction of the hole 34 (not overlapping). Thereby, it is possible to prevent the compression member 50 from closing the hole 34, and even when the compression member 50 is compressed, the temperature sensor 40 can face the hole 34 or enter the hole 34.

[0085] FIGS. 7 and 8 are diagrams of a temperature sensing assembly according to a comparative example.

[0086] In the temperature sensing assembly 10' according to the comparative example, a hole facing the temperature sensor 40 may not be formed in the bridge 30, and the compression member 50' can cover the temperature sensor 40. That is, the temperature sensor 40 can be embedded in the compression member 50'.

[0087] Therefore, there is no problem when the compression member 50' is weakly compressed, but when the compression member 50' is strongly compressed, there is a risk of damage to the temperature sensor 40.

[0088] On the one hand, as described above, in the case of the temperature sensing assembly 10 according to the present invention, the compression member 50 does not interfere with the temperature sensor 40, and the hole 34 of the bridge 30 is formed so as to face the temperature sensor 40. Even if the compression member 50 is excessively crimped, the temperature sensor 40 can enter the hole 34. Thereby, damage to the temperature sensor 40 can be prevented.

[0089] FIG. 9 is an exploded perspective view of a temperature sensing assembly according to another embodiment of the present invention.

[0090] The temperature sensing assembly 10' according to another embodiment of the present invention employs the above-described embodiment except for the compression member 50a.

[0091] The compression members 50a located on both sides of the temperature sensor 40 can be connected to each other within a range where they do not interfere with the temperature sensor 40. The compression members 50a can be integrally formed.

[0092] The compression member 50a can surround the temperature sensor 40. That is, a part of the compression member 50a can be located on one side of the temperature sensor 40, and another part of the compression member 50a can be located on the other side of the temperature sensor 40.

[0093] More specifically, a through hole is formed in the compression member 50a, and the temperature sensor 40 can be located within the through hole. The through hole can face the hole 34 formed in the bridge 30.

[0094] In the case of this embodiment, there is an advantage of simplifying the adhesion process of the compression member 50a to the substrate 20 and / or the bridge 30.

[0095] The above description merely exemplarily explains the technical idea of the present invention, and those with ordinary knowledge in the technical field to which the present invention pertains can make various modifications and variations without departing from the essential characteristics of the present invention.

[0096] Therefore, the embodiments disclosed in the present invention are for illustrative purposes rather than for limiting the technical idea of the present invention, and the scope of the technical idea of the present invention is not limited by such embodiments.

[0097] The protection scope of the present invention shall be construed according to the following claims, and all technical ideas within the equivalent scope should be construed as being included in the scope of rights of the present invention.
