Description

Technical Field

[0001] This disclosure relates to battery packs, electronic devices, and vehicles, and more specifically, to battery packs for ensuring easy installation of temperature sensors and enhancing the reliability of temperature measurements of multiple battery cells.

[0002] This application claims priority to Korean Patent Application No. 10-2020-0137092, filed in Korea on October 21, 2020, the disclosure of which is incorporated herein by reference. Background Technology

[0003] Recently, with the rapid growth in demand for portable electronic products such as laptops, cameras and mobile phones, as well as the widespread development of electric vehicles, energy storage batteries, robots and satellites, there is a great deal of research being conducted on high-performance rechargeable secondary batteries.

[0004] Currently, commercially available rechargeable batteries include nickel-cadmium batteries, nickel-metal hydride batteries, nickel-zinc batteries, and lithium rechargeable batteries. Among them, lithium rechargeable batteries have almost no or no memory effect, and therefore attract more attention than nickel-based rechargeable batteries due to their advantages of being easily rechargeable, having extremely low self-discharge rate, and high energy density.

[0005] These lithium-ion rechargeable batteries primarily use lithium oxides and carbon materials as the positive and negative electrode active materials, respectively. Additionally, this lithium-ion rechargeable battery includes: an electrode assembly, in which a positive electrode plate coated with positive and negative electrode active materials is disposed with a separator inserted between it; and an external component, namely the battery casing, for sealingly housing the electrode assembly and the electrolyte together.

[0006] Additionally, depending on the shape of the external components, lithium secondary batteries can be classified as: can-type battery cells, in which the electrode assembly is contained in a metal can; and pouch-type battery cells, in which the electrode assembly is contained in a pouch made of aluminum laminate.

[0007] In the case of can-type battery cells, the metal can containing the electrode assembly can be manufactured in a cylindrical shape. Can-type battery cells can be used to construct battery packs, which include module housings for accommodating multiple secondary batteries and busbars configured to electrically connect the multiple battery cells.

[0008] Furthermore, existing battery pack technologies primarily measure temperature changes based on the charging and discharging of multiple battery cells to determine battery operating status or lifespan. Existing battery pack technologies use temperature sensors to measure the temperature of multiple battery cells. In this case, adhesive tape is typically used to fix the temperature sensors to the locations where temperature measurements are required.

[0009] However, the manual fixation of temperature sensors using adhesive tape in existing technologies has increased manufacturing time and costs. Furthermore, when using adhesive tape to fix the temperature sensor, its position can change depending on the operator.

[0010] Therefore, the problem with existing battery packs is that even when the battery cells are at the same temperature, there are still discrepancies in the temperature values ​​measured by temperature sensors. Consequently, it is difficult to manage the battery pack's lifespan or safety by measuring its temperature. Summary of the Invention

[0011] Technical issues

[0012] This disclosure is designed to address the problems of the prior art, and therefore aims to provide a battery pack for ensuring easy installation of temperature sensors and enhancing the reliability of temperature measurement of multiple battery cells.

[0042] Preferred embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. Before the description, it should be understood that the terminology used in the specification and appended claims should not be construed as limited to its common or dictionary meaning, but rather is interpreted based on the principle of allowing the inventor to properly define the terminology to provide the best interpretation, and on the meaning and concepts corresponding to the technical aspects of the present disclosure.

[0043] Therefore, the descriptions presented herein are merely preferred examples for illustrative purposes only and are not intended to limit the scope of this disclosure. It should be understood that other equivalents and modifications may be made thereto without departing from the scope of this disclosure.

[0044] Figure 1 A perspective view of a battery pack according to an embodiment of the present disclosure is provided for illustrative purposes. Figure 2 An exploded perspective view of a battery pack according to an embodiment of the present disclosure is shown for illustrative purposes. Figure 3 For example Figure 1 A magnified view of part A. For reference purposes, in Figure 2 In this disclosure, the battery pack 100 includes two components, each of which is connected to a first frame 131 and a second frame 132. Figure 2 In the diagram, for ease of description, only one component located on the relatively front side is shown in a decomposed form among the two components.

[0045] refer to Figure 1 According to an embodiment of the present disclosure, the battery pack 100 includes a plurality of battery cells 110, a temperature measurement unit 160, a temperature sensor 120, and a module housing 130.

[0046] Specifically, each of the plurality of battery cells 110 may be a rechargeable lithium secondary battery. Battery cell 110 may be a can-type battery cell 110. Battery cell 110 may include a positive terminal 111 and a negative terminal 112 respectively at one end and the other end. Battery cell 110 may include a cylindrical can.

[0047] The configuration of the battery cell 110 is well known to those skilled in the art at the time of filing this application, and therefore will not be described in detail here. Furthermore, the battery pack 100 according to this disclosure is not limited to the configuration of the battery cell 110 having a specific shape. That is, various types of battery cells known at the time of filing can be used in the battery pack 100 according to this disclosure.

[0048] Furthermore, the battery pack 100 of this disclosure may further include a plurality of metal plates 170. The metal plates 170 may be configured to electrically connect a plurality of cylindrical battery cells 110. The metal plates 170 may contain conductive metals. The metal plates 170 may contain at least one of, for example, copper, nickel, and aluminum.

[0049] In addition, the metal plate 170 can be installed on the left or right side of the module housing 130.

[0050] Additionally, the temperature measuring unit 160 may be configured to detect the temperature of at least one of the plurality of battery cells 110 and transmit an electrical signal to the temperature measuring unit 160. The temperature measuring unit 160 may be configured to calculate the temperature of the battery cell 110 via an electrical signal transmitted from the temperature sensor 120. The temperature measuring unit 160 may include a connector C configured to be connected to the temperature sensor 120.

[0051] Additionally, the temperature sensor 120 can function as a sensor that converts heat into an electrical signal. For example, the temperature sensor 120 may include a wire portion 121 and a thermistor portion 122. The wire portion 121 may include a wire for transmitting the electrical signal. For example, as... Figure 2 As illustrated, conductor portion 121 may include two conductors. The two conductors may be wound within an electrical insulating sheath.

[0052] The thermistor portion 122 can be configured to change its resistance according to temperature changes in the battery cell 110. The thermistor portion 122 can be electrically connected to the end of the wire portion 121. The thermistor portion 122 is located at the end of the wire portion 121 and can have a larger cross-sectional area than the wire portion 121. The thermistor portion 122 can have a cylindrical shape. When a constant current flows in the wire portion 121 and the resistance of the thermistor portion 122 changes according to temperature changes in the battery cell 110, the temperature measuring unit 160 can calculate the external temperature of the battery cell 110 based on the voltage received from the temperature sensor 120.

[0053] Additionally, the module housing 130 may be made of an electrically insulating material. For example, the module housing 130 may be made of polyvinyl chloride (PVC). The module housing 130 may include a sidewall portion 133. The sidewall portion 133 may be configured to form an internal space for accommodating a plurality of battery cells 110. For example, as Figure 1 As illustrated, the sidewall portion 133 may have four sides including a front wall, a rear wall, a left wall, and a right wall. Additionally, the module housing 130 may include an upper wall for covering the upper portions of the plurality of battery cells 110 and a lower wall for covering the lower portions of the plurality of battery cells 110. For reference purposes, this disclosure... Figure 1 The positive and negative directions of the X-axis can refer to the right and left directions, respectively. The positive and negative directions of the Y-axis can refer to the backward and forward directions, respectively. The positive and negative directions of the Z-axis can refer to the upward and downward directions, respectively.

[0054] Furthermore, the module housing 130 may have a box-shaped body as a whole. Additionally, the module housing 130 may have multiple openings O within its body to accommodate multiple battery cells 110. For example, the module housing 130 may have multiple cylindrical openings O, such as... Figure 2 exemplified in .

[0055] Additionally, the module housing 130 may include a first frame 131 and a second frame 132 forming spaces for accommodating a plurality of cylindrical battery cells 110. The first frame 131 may be configured to have a rear end connected to the front end of the second frame 132. In this case, the connection method may be, for example, a bolted connection.

[0056] Additionally, an opening 134 may be formed in the sidewall portion 133. The opening 134 may be formed by partially perforating the sidewall portion 133 so that at least one of the plurality of battery cells 110 may be partially exposed to the outside.

[0057] The module housing 130 may include a receiving portion 135. The receiving portion 135 is a space communicating with the opening 134 and serves as a receiving space for the thermistor portion 122 of the temperature sensor 120. In other words, the receiving portion 135 may be a space located inside the module housing 130 relative to the opening 134. The receiving portion may have an inlet communicating with the opening.

[0058] refer to Figure 1 and Figure 3 The receiving portion 135 may have an entrance on its upper side (in the +Z axis direction). For example, the entrance refers to the space above the receiving portion 135, i.e., relative to... Figure 1 The receiving portion 135 is located in the +Z axis direction and can be formed by partially connecting the first frame 131 and the second frame 132.

[0059] The module housing 130 may include a retaining rib 136. The retaining rib 136 may be configured to partially cover the inlet. The retaining rib 136 may be configured to prevent the thermistor portion 122 of the temperature sensor 120, inserted into the receiving portion 135, from escaping to the outside of the receiving portion 135. The retaining rib 136 may be a portion extending from a side wall. The retaining rib 136 may be configured to cover one side (rear side) or the other side (front side), or both, relative to the center of the inlet of the receiving portion 135. The retaining rib 136 may be provided to the second frame 132.

[0060] According to this configuration of the present disclosure, since the present disclosure includes a module housing 130 having a receiving portion 135 configured to accommodate a temperature sensor 120 and a retaining rib 136 configured to cover the inlet of the receiving portion 135, the end of the temperature sensor 120 can be effectively prevented from escaping to the outside in the +Z axis direction after it is inserted into the space of the receiving portion 135. Therefore, unlike the prior art that uses adhesive tape to fix the end of the temperature sensor 120, the adhesive tape is unnecessary, and thus has the advantages of reducing material costs and shortening manufacturing process time.

[0061] Figure 4 For example, viewing from another angle without including the first frame. Figure 3 The diagram shows the portion that can be contained within.

[0062] refer to Figure 4 as well as Figure 3The fixing rib 136 may have a step S, which is formed in a portion therein and has different protruding lengths toward the battery cell 110. The fixing rib 136 may be located on one side of the inlet of the receiving portion 135. The fixing rib 136 may be formed such that its protruding length toward the battery cell 110 becomes larger as it gets closer to the inlet (rear side) of the receiving portion 135. That is, the step S refers to the portion of the fixing rib 136 where the protruding length toward the battery cell 110 gradually changes.

[0063] Additionally, the end of the temperature sensor 120 can be configured to be positioned at the step S of the fixing rib 136. That is, the wire portion 121 of the temperature sensor 120 can be configured to be positioned at the relatively long portion of the fixing rib 136 that protrudes toward the battery cell 110.

[0064] Furthermore, after passing through the center portion of the inlet, the end of the temperature sensor 120 can move toward the step of the fixing rib 136. That is, after the thermistor portion 122 of the temperature sensor 120 is inserted into the space of the receiving portion 135, the thermistor portion 122 can move to the lower portion of the fixing rib 136. Therefore, the upward movement of the thermistor portion 122 can be restricted by the step of the fixing rib 136.

[0065] Therefore, according to this configuration of the present disclosure, since steps S of varying protruding lengths toward the battery cell 110 are formed in a portion of the fixing rib 136, the end of the temperature sensor 120 can be supported toward the battery cell 110 by means of the end of the fixing rib 136. Thus, the end of the temperature sensor 120 can be positioned closer to the battery cell 110, or can be in close contact with the outer surface of the battery cell 110. Therefore, the present disclosure has the advantage of measuring the temperature of the battery cell 110 more quickly and accurately via the temperature sensor 120.

[0066] Additionally, refer to again Figure 4 This disclosure may also include an adhesive 140 configured to be injected into the space of the receiving portion 135. The adhesive 140 may be an adhesive 140 injected into the interior space of the receiving portion 135 and then cured. The adhesive 140 may be transparent and electrically insulating. The adhesive 140 may be a glue or a hot melt resin. For example, the adhesive 140 may comprise at least one of polyamide resins, polyimide resins, epoxy resins, and acrylic resins.

[0067] For example, such as Figure 4 As illustrated, adhesive 140 can be configured to fix the position of the thermistor portion 122 of temperature sensor 120. That is, adhesive 140 can fix the end of temperature sensor 120.

[0068] Figure 5 For corresponding Figure 4 A cross-sectional view of the housing portion of the battery pack according to a second embodiment of the present disclosure is shown.

[0069] refer to Figure 5 In the battery pack 100 according to the second embodiment of this disclosure, unlike Figure 3 The fixing rib 136 may have a fixing groove H further formed therein. The fixing groove H may be recessed into a portion of the fixing rib 136. That is, the fixing groove H may be formed to recess from the end of the fixing rib 136 into the body. The fixing groove H may be configured such that the wire portion 121 of the temperature sensor 120 is partially inserted.

[0070] Therefore, according to this configuration of the present disclosure, since the fixing groove H, in which the wire portion 121 is configured to be partially inserted, is formed in a portion of the fixing rib 136, the wire portion 121 of the temperature sensor 120 can be stably fixed to the fixing groove H, and the deviation in the separation distance from the battery cell 110 can be effectively reduced. That is, in the present disclosure, since the thermistor portion 122 of the temperature sensor 120 can be stably fixed and its position can be continuously maintained by means of the fixing groove H, the conventional problem of reduced reliability of the temperature measured from the temperature measuring unit 160 can be solved when the position of the end of the temperature sensor 120 is different for various manufactured battery packs 100.

[0071] Figure 6 For corresponding Figure 4 A cross-sectional view of the housing portion of the battery pack according to a third embodiment of the present disclosure is shown.

[0072] refer to Figure 6 In the battery pack 100 according to the third embodiment of this disclosure, at least one pressing protrusion P may be provided in the space of the receiving portion 135. The pressing protrusion P may protrude from the inner surface of the internal space of the receiving portion 135, such that the thermistor portion 122 is in close contact with the portion of the battery cell 110 exposed through the opening 134. The pressing protrusion P may have a shape that protrudes toward the thermistor portion 122. For example, as Figure 6 As illustrated, the three pressing protrusions P can be configured to protrude from the inner surface of the receiving portion 135 toward the thermistor portion 122, such that the thermistor portion 122 is in close contact with the battery cell 110.

[0073] Therefore, according to this configuration of the present disclosure, since at least one pressing protrusion P is disposed in the space of the receiving portion 135, the thermistor portion 122 of the temperature sensor 120 can be supported toward the battery cell 110 by means of the pressing protrusion P. Therefore, the thermistor portion 122 of the temperature sensor 120 can be disposed closer to the battery cell 110, or can be in close contact with the outer surface of the battery cell 110. Therefore, the present disclosure has the advantage of measuring the temperature of the battery cell 110 more quickly and accurately via the temperature sensor 120.

[0074] In addition, refer to again Figure 6 It can provide at least two pressable protrusions P. For example, such as Figure 6 As illustrated, three pressing protrusions P may be formed on the inner surface of the receiving portion 135. Furthermore, two or more pressing protrusions P may be spaced apart from each other by a predetermined distance and may have different protrusion lengths L facing the thermistor portion 122 of the temperature sensor 120. For example, as... Figure 6 As illustrated, among the three pressing protrusions P, the pressing protrusion P located on the lower side may have a greater protruding length L toward the thermistor portion 122 compared to the pressing protrusion P located on the upper side. Therefore, the lower portion of the thermistor portion 122 may be positioned relatively closer to the battery cell 110 than its upper portion.

[0075] Therefore, according to this configuration of the present disclosure, since the present disclosure includes at least two or more pressing protrusions P with different protruding lengths L, it can help position the thermistor of the temperature sensor 120 corresponding to the outer surface of the battery cell 110. That is, since the two or more pressing protrusions P can adjust the receiving position of the thermistor portion 122 of the temperature sensor 120, the thermistor portion 122 can maintain a constant distance from the outer surface of the battery cell 110, or can slightly increase its area of ​​close contact with the outer surface of the battery cell 110.

[0076] Figure 7 For corresponding Figure 4 A cross-sectional view of the housing portion of the battery pack according to the fourth embodiment of the present disclosure is shown.

[0077] refer to Figure 7 When with Figure 4 Compared to the battery pack 100 of the present disclosure, the battery pack 100 according to the fourth embodiment of the present disclosure may further include an elastic member 150. For example, the elastic member 150 may include a material having elastic deformation or elastic recovery force. The material may be any one or more of, for example, silicone, urethane, rubber, and sponge.

[0078] Additionally, the elastic member 150 can be pre-accommodated in the space of the receiving portion 135 before the end of the temperature sensor 120 is inserted. The elastic member 150 can be configured to press the thermistor portion 122. That is, when the thermistor portion 122 of the temperature sensor 120 enters the receiving portion 135, the volume of the elastic member 150 can be reduced due to elastic deformation, and when the insertion process of the thermistor portion 122 ends, the volume of the elastic member 150 can be expanded again due to elastic force, and the thermistor portion 122 of the temperature sensor 120 can be pressed into close contact with the outer surface of the battery cell 110 by the elastic force of the elastic member 150.

[0079] Therefore, according to this configuration of the present disclosure, since the present disclosure includes an elastic member 150 configured to press the thermistor portion 122, the thermistor portion 122 of the temperature sensor 120 can be disposed closer to the battery cell 110 or can be in close contact with the outer surface of the battery cell 110. Therefore, the present disclosure has the advantage of measuring the temperature of the battery cell 110 more quickly and accurately via the temperature sensor 120.

[0080] In addition, the battery pack 100 according to embodiments of the present disclosure also includes various devices (not illustrated) for controlling the charging and discharging of the battery pack 100, such as a BMS (battery management system), a current sensor, and a fuse.

[0081] Additionally, the electronic device (not illustrated) according to embodiments of this disclosure includes at least one battery pack 100 as described above. The electronic device may also include a device housing (not illustrated) having a receiving space for accommodating the battery pack 100 and a display unit through which a user can check the charging status of the battery pack 100.

[0082] Furthermore, the battery pack 100 according to embodiments of this disclosure may be included in a vehicle such as an electric vehicle or a hybrid vehicle. That is, a vehicle according to embodiments of this disclosure may include at least one battery pack 100 as described above. The battery pack 100 may be installed in the vehicle body.

[0083] Furthermore, although directional terms (such as above, below, left, right, front, and back) are used in the specification, it will be apparent to those skilled in the art that, for ease of interpretation, these terms only indicate relative positions and may vary based on the position of the observer or object.

[0084] Previously, embodiments and experimental examples have been described in detail to illustrate this disclosure more specifically, but this disclosure is not limited to such embodiments and experimental examples. Embodiments according to this disclosure may be modified in various other forms, and the scope of this disclosure should not be construed as limited to the embodiments described above. Embodiments of this disclosure are provided to more fully explain this disclosure to those skilled in the art.
