Description

Temperature sensing assembly and battery module including the same {TEMPERATURE SENSING ASSEMBLY AND BATTERY MODULE INCLUDING THE SAME}

The present invention relates to a temperature sensing assembly that senses the temperature of a cell stack and a battery module including the same.

In modern society, as the use of portable devices such as mobile phones, laptops, camcorders, and digital cameras becomes routine, the development of technologies in fields related to the above mobile devices is becoming more active. In addition, secondary batteries that can be charged and discharged are a way to solve air pollution from existing gasoline vehicles that use fossil fuels, and are used in electric vehicles (EV), hybrid electric vehicles (HEV), and plug-in hybrid electric vehicles ( As it is used as a power source for batteries such as P-HEV), the need for development of secondary batteries is increasing.

Currently commercialized secondary batteries include nickel cadmium batteries, nickel hydrogen batteries, nickel zinc batteries, and lithium secondary batteries. Among these, lithium secondary batteries rarely have a memory effect compared to nickel-based secondary batteries, so they can be freely charged and discharged. , it is in the spotlight for its very low self-discharge rate and high energy density.

These lithium secondary batteries mainly use lithium-based oxide and carbon material as positive and negative electrode active materials, respectively. A lithium secondary battery includes an electrode assembly in which a positive electrode plate and a negative electrode plate coated with the positive electrode active material and the negative electrode active material are disposed with a separator in between, and an exterior material, that is, a battery case, that seals and stores the electrode assembly together with an electrolyte solution.

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 in a pouch of an aluminum laminate sheet, depending on the shape of the exterior material.

In the case of secondary batteries used in small devices, 2-3 battery cells are placed, but in the case of secondary batteries used in medium to large devices such as automobiles, a battery module is made by electrically connecting multiple battery cells. This is used.

These battery modules have improved capacity and output by connecting multiple battery cells in series or parallel to each other to form a battery cell stack. Additionally, one or more battery modules may be mounted together with various control and protection systems such as a battery management system (BMS) and a cooling system to form a battery pack.

Meanwhile, when the battery cells included in the battery module experience overvoltage, overcurrent, or overheating, the safety and operating efficiency of the battery module are greatly problematic. For example, when the pressure or temperature of the battery increases, the decomposition reaction of the active material and a number of side reactions proceed, causing the temperature of the battery to rise rapidly, which in turn accelerates the reaction between the electrolyte and the electrodes. Ultimately, a thermal runaway phenomenon occurs in which the temperature of the battery rises rapidly. If the temperature rises above a certain level, the battery may ignite, and the increased internal pressure of the battery causes the battery cell and the battery module containing it to explode.

Therefore, a means for detecting temperature changes in the battery cells is needed, and therefore, temperature sensors such as thermistors are placed within the battery module to check and control the operating status in real time or at regular intervals.

One problem that the present invention seeks to solve is to provide a temperature sensing assembly that prevents damage to the temperature sensor and has improved accuracy and reliability, and a battery module including the same.

A temperature sensing assembly according to an embodiment of the present invention includes a substrate; a temperature sensor mounted on the substrate; a bridge coupled to the substrate and having a hole facing the temperature sensor; and compression members located on both sides of the temperature sensor between the bridge and the substrate.

The bridge may be coupled to the upper side of the substrate.

The bridge includes a main body to which the substrate is coupled; and an extension part extending from the main body, forming a predetermined gap with the substrate, and contacting the compression member.

The hole may be formed in the extension part.

The substrate includes a coupling portion coupled to the bridge; And it may include a mounting part on which the temperature sensor is mounted at a predetermined distance from the bridge.

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

The substrate may further include an inclined portion that connects the coupling portion and the mounting portion and is formed at an angle with respect to the mounting portion.

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

The hole may non-overlap with the compression member with respect to the penetration direction of the hole.

A battery module according to an embodiment of the present invention includes a housing; A cell stack containing a plurality of battery cells accommodated in the housing and arranged side by side with each other; And it may include a temperature sensing assembly that senses the temperature of the cell stack. The temperature sensing assembly includes a substrate located on an upper side of the cell stack; a temperature sensor mounted on the substrate; a bridge coupled to the substrate and having a hole facing the temperature sensor; and compression members located on both sides of the temperature sensor between the bridge and the substrate.

At least a portion of the temperature sensing assembly may be located between the upper plate of the housing and the cell stack.

According to a preferred embodiment of the present invention, even if the cell stack is expanded or pressure is applied to the substrate due to tolerances during assembly of the battery module, damage to the temperature sensor due to the compression member can be prevented, and the substrate can be used to prevent the cell from being damaged. It can remain adjacent to or in close contact with the laminate. As a result, the accuracy and reliability of the temperature sensor can be improved.

Additionally, since the compression member does 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 member is excessively compressed. This can prevent damage to the temperature sensor.

A temperature sensor 40 may be mounted on the substrate 20. The temperature sensor 40 may be a device capable of detecting temperature. The temperature sensor 40 may be fixed on the substrate 20 by soldering.

The temperature sensor 40 may include a thermistor. A thermistor is a semiconductor device that utilizes the phenomenon of resistance changing depending on temperature. Thermistors have the advantage of being small in size and capable of measuring rapid or detailed temperature changes.

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

Temperature information measured by the temperature sensor 40 may be transmitted to another device outside the battery module 100. For example, the temperature information measured by the temperature sensor 40 may be transmitted to a battery management system (BMS) outside the battery module 100 and used to control the battery module 100.

The bridge 30 may 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.

The bridge 30 may be formed to be long approximately in the direction of the overall length of the cell stack 110 . The bridge 30 may include a plurality of areas with different inclinations. The bridge 30 may be formed integrally, but is not limited thereto.

The bridge 30 may be rotatably connected to the bus bar frame 130. In more detail, the bridge 30 may be hingedly connected to the top 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 around an axis parallel to the stacking direction of the cell stack 110.

A hole 34 may be formed in the bridge 30 to face the temperature sensor 40 on the substrate 20. Accordingly, even if the substrate 20 is deformed toward the bridge 30, the temperature sensor 40 can be inserted into the hole 34. That is, the temperature sensor 40 can be prevented from interfering with the bridge 30.

The substrate 20 may include a coupling portion 21 coupled to the bridge 30 and a mounting portion 22 on which the temperature sensor 40 is mounted at a predetermined distance from the bridge 30. The substrate 20 may further include an inclined portion 23 that connects the coupling portion 21 and the mounting portion 22 and is formed at an angle with respect to the mounting portion 22 .

The bridge 30 includes a main body portion 31 to which the substrate 20 is coupled, and an extension portion 32 that extends from the main body portion 31 and forms a predetermined gap with the substrate 20 and is in contact with the compression member 50. ) may include. The bridge 30 may further include a connection portion 33 rotatably connected to the bus bar frame 130.

The coupling portion 21 of the substrate 20 can be adhered to the bridge 30, and thus can be simply coupled to the bridge 30. That is, an adhesive layer 60 may be provided between the coupling portion 21 and the bridge 30.

The coupling portion 21 may be coupled to the main body portion 31 of the bridge 30. The coupling portion 21 of the substrate 20 may 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 closely adhered and coupled with the adhesive layer 60 interposed therebetween.

For example, the adhesive layer 60 may be a double-sided tape.

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 to this.

The mounting portion 22 of the substrate 20 may be spaced apart from the bridge 30 by a predetermined distance. In more detail, the mounting portion 22 may be spaced at a predetermined distance from the extension portion 32 of the bridge 30. Due to the above gap, the temperature element 40 and the compression member 50 can be disposed between the substrate 20 and the bridge 30.

The extension portion 32 of the bridge 30 may extend from the main body portion 31. The extension portion 32 and the main body portion 31 may be parallel to each other or may be formed at different inclinations.

The mounting portion 22 of the substrate 20 may be formed parallel to the extension portion 32 of the bridge 30. Accordingly, the spacing can be formed to be constant in the longitudinal direction of the mounting portion 22.

A temperature sensor 40 may be mounted on the mounting portion 22. The temperature sensor 40 may be fixed on the mounting portion 22 by soldering.

The temperature sensor 40 may face the hole 34 formed in the bridge 30. In more detail, a hole 34 facing the temperature sensor 40 may be formed in the extension portion 32 of the bridge 30. Accordingly, 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, the temperature sensor 40 can be prevented from interfering with the extension portion 32 of the bridge 30.

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 may be formed integrally with the coupling portion 21 and the mounting portion 22. By the inclined portion 23, the coupling portion 21 and the mounting portion 22 can form a substantially level difference. As a result, the coupling portion 21 is in close contact with the main body portion 31 of the bridge 30, and the mounting portion 22 can be spaced a predetermined distance from the extension portion 32 of the bridge 30.

The connection portion 33 of the bridge 30 may have a shape bent downward from the main body portion 31. The connection portion 33 may be rotatably connected to the bus bar frame 130.

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

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

For example, a lower adhesive layer may be provided between the bottom 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 may be double-sided tape.

As a result, it is possible to prevent the mounting portion 22 of the substrate 20 and the extension portion 32 of the bridge 30 from opening up or being deformed in an unintended direction.

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

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

However, it is not limited to this, and the compression member 50 may be configured to exert elastic force by its shape, such as a spring.

Compression members 50 may be located on both sides of temperature sensor 40. That is, some of the compression members 50 may be located on one side of the temperature sensor 40, and other portions of the compression members 50 may be located on the other side of the temperature sensor 40.

For example, the compression member 50 may 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. there is.

As a result, the compression member 50 does not interfere with the temperature sensor 40, and pressure can be prevented from being applied to the temperature sensor 40 when the compression member 50 is compressed. In more detail, even if the cell stack 110 is expanded or pressure is applied to the substrate 20 due to tolerances during assembly of the battery module 100, damage to the temperature sensor 40 is caused by the compression member 50. pressure can be prevented, and the substrate 20 can be maintained adjacent to or in close contact with the cell stack 110. Accordingly, the accuracy and reliability of the temperature sensor 40 can be improved.

The hole 34 formed in the bridge 30 may non-overlap the compression member 50 with respect to the penetration direction of the hole 34. This prevents the compression member 50 from blocking the hole 34, and allows the temperature sensor 40 to face the hole 34 or enter the hole 34 even when the compression member 50 is compressed. .

7 and 8 are diagrams of a temperature sensing assembly according to a comparative example.

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' may cover the temperature sensor 40. . That is, the temperature sensor 40 may be buried in the compression member 50'.

Accordingly, there is no problem when the compression member 50' is slightly compressed, but there is a risk of damage to the temperature sensor 40 when the compression member 50' is strongly compressed.

On the other 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 allows the temperature sensor 40. Since it is formed to face the temperature sensor 40, the temperature sensor 40 can enter the hole 34 even if the compression member 50 is excessively compressed. This can prevent damage to the temperature sensor 40.

Figure 9 is an exploded perspective view of a temperature sensing assembly according to another embodiment of the present invention.

The temperature sensing assembly 10' according to another embodiment of the present invention uses the previously described embodiment except for the compression member 50a.

Compression members 50a located on both sides of the temperature sensor 40 may be connected to each other in a range that does not interfere with the temperature sensor 40. The compression member 50a may be formed integrally.

The compression member 50a may surround the temperature sensor 40. That is, some of the compression members 50a may be located on one side of the temperature sensor 40, and other portions of the compression members 50a may be located on the other side of the temperature sensor 40.

In more detail, a through hole is formed in the compression member 50a, and the temperature sensor 40 may be located within the through hole. The through hole may face the hole 34 formed in the bridge 30.

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

The above description is merely an illustrative explanation of the technical idea of the present invention, and various modifications and variations will be possible to those skilled in the art without departing from the essential characteristics of the present invention.
