Description

[Technical field]

[0001] The present invention relates to a battery pack and an energy storage device including the same.

[0002] This application claims priority to Korean Patent Application No. 10-2021-0184402 filed on December 21, 2021, and the entire contents disclosed in the specification and drawings of that application are incorporated herein by reference. [Background technology]

[0003] Currently, commercially available secondary batteries include nickel-cadmium batteries, nickel-metal hydride batteries, nickel-zinc batteries, and lithium secondary batteries. Of these, lithium secondary batteries are in the spotlight for their advantages over nickel-based secondary batteries, such as the almost complete absence of memory effect, which allows for free charging and discharging, a very low self-discharge rate, and a high energy density.

[0004] This type of lithium secondary battery mainly uses a lithium-based oxide and a carbon material as a positive electrode active material and a negative electrode active material, respectively, and includes an electrode assembly in which a positive electrode plate and a negative electrode plate coated with such a positive electrode active material and a negative electrode active material are arranged with a separator sandwiched therebetween, and an exterior material, such as a battery case, that encloses the electrode assembly together with an electrolyte.

[0005] In general, lithium secondary batteries are classified according to the shape of their exterior material into can-type secondary batteries in which an electrode assembly is housed in a metal can and pouch-type secondary batteries in which an electrode assembly is housed in a pouch made of an aluminum laminate sheet.

[0006] Such secondary batteries are widely used not only in small devices such as portable electronic devices, but also in medium- and large-sized devices such as electric vehicles and energy storage systems (ESS), and the use of such batteries is rapidly increasing. In addition, energy storage systems (ESS) for storing generated electricity have been attracting much attention in recent years as issues such as power shortages and environmentally friendly energy are being raised. Representatively, if such energy storage devices are used, it is easy to build a power management system such as a smart grid system, so that it is possible to easily adjust the supply and demand of electricity in a specific region or city. In addition, as commercialization of electric vehicles becomes widespread, such energy storage devices can also be applied to electric charging stations that can charge electric vehicles.

[0007] Furthermore, residential energy storage devices have been widely used recently to store and supply power for use in buildings such as homes and buildings, and a core component of such residential energy storage devices is a battery pack.

[0008] Various battery packs, including battery packs used in residential ESSs, include multiple battery cells (secondary batteries) to increase capacity and / or output. In particular, to increase the energy density of the battery pack, the multiple battery cells are often arranged in a dense state in a very narrow space.

[0009] In the case of conventional battery packs, the installation and mounting methods for connecting the battery pack to electrical components such as an inverter differ depending on the country or region in which the battery pack is installed or mounted. This means that even though the battery packs are the same product, there is a problem in that additional parts or dedicated parts are required for compatibility when installing or mounting the product or for future management.

[0010] This has led to an increasing need for battery packs that can be compatible with various types of electrical components.

[0011] Therefore, there is a strong demand for a solution to provide a battery pack and an energy storage device including the same that can increase installation and mounting compatibility and improve installation and mounting workability.

[0036] Therefore, it should be understood that the embodiment described in this specification and the configurations shown in the drawings are merely the most preferred embodiment of the present invention and do not represent the entire technical idea of ​​the present invention, and therefore there may be various equivalents and modifications that can be substituted therefor at the time of this application.

[0037] Meanwhile, in this specification, directional terms such as up, down, left, right, front, and back are used, but these terms are used merely for ease of explanation, and it will be obvious to those skilled in the art of the present invention that they may vary depending on the position of the object in question, the position of the observer, etc.

[0038] Phrases such as "first," "second," and the like may be used to describe various components. These phrases are used for the purpose of distinguishing the components from other components, and do not limit the nature, order, or sequence of the components.

[0039] FIG. 1 is a diagram for explaining a battery pack according to one embodiment of the present invention, FIG. 2 is a diagram for explaining the connection between the battery pack of FIG. 1 and electrical components of a first connection type, and FIG. 3 is a diagram for explaining the connection between the battery pack of FIG. 1 and electrical components of a second connection type.

[0040] 1 to 3, a battery pack 10 may include a battery module 100, a pack case 200, and a connection guide unit 300.

[0041] The battery module 100 may include one or more battery cells 110. Here, each battery cell 110 may refer to a secondary battery. The secondary battery may include an electrode assembly, an electrolyte, and a battery case. Furthermore, the battery cell 110 provided in the battery module 100 may be a pouch-type secondary battery. However, other types of secondary batteries, such as so-called cylindrical batteries and prismatic batteries, may also be adopted in the battery module 100 of the present invention.

[0042] The pack case 200 may accommodate the battery module 100. The pack case 200 may be provided with an accommodation space for accommodating the battery module 100. In addition, components such as a control module connected to the battery module 100 and for controlling and managing the battery pack 100 and various electrical components may be accommodated together in the accommodation space.

[0043] The connection guide unit 300 may be provided on at least one side of the pack case 200. The connection guide unit 300 may be electrically connected to the control module, the battery module 100, etc., and may be configured to be connectable to electrical components A and B of two or more connection types.

[0044] Here, the two or more connection types of electrical components A and B may be electrical components required for installation or mounting, for example, components for connecting an inverter, or the inverter itself. That is, the connection guide unit 300 may be configured to guide the connection between the battery pack 10 and an inverter.

[0045] In this embodiment, the connection guide unit 300 can be used to guide not only one type of electrical component, but two or more types of electrical components A and B so that they can be electrically connected to each other. This significantly increases the compatibility of a single product with various types of electrical components such as inverters when installing, mounting, or inspecting the battery pack 10.

[0046] As a result, the battery pack 10 according to this embodiment can remarkably improve compatibility and workability during installation, attachment, or future inspection. In addition, the battery pack 10 according to this embodiment is provided to be compatible with two or more connection types of electrical components A and B, so that inconvenience during installation, attachment, or inspection due to incompatible connection types is minimized, and since the attachment of compatible components is not required, both the ease of work and cost reduction can be achieved.

[0047] The connection guide unit 300 according to this embodiment will be described in more detail below.

[0048] The connection guide unit 300 may include a first connection guider 310 and a second connection guider 330 .

[0049] The first connection guider 310 may be provided to be connectable to a first connection type electrical component A. Here, the first connection type electrical component A may be a component that guides a connection to an inverter applied in the United States, or may be an inverter applied in the United States.

[0050] The second connection guider 330 may be provided so as to be connectable to an electrical component B of a second connection type that is different from the electrical component A of the first connection type. Here, the electrical component B of the second connection type may be a component that guides a connection to an inverter applied in Europe, or may be an inverter applied in Europe.

[0051] In this manner, in this embodiment, a single product battery pack 10 that is compatible with both electrical components A and B having two different connection types can be provided by using the first connection guider 310 and the second connection guider 330. For example, the battery pack 10 according to this embodiment can provide a battery pack 10 that is compatible in both the United States and Europe by using the first connection guider 310 and the second connection guider 330.

[0052] The first connection guider 310 and the second connection guider 330 may be provided on different sides of the pack case 200. In this embodiment, the first connection guider 310 and the second connection guider 330 are provided on different sides of the pack case 200, so that problems such as incorrect assembly by workers or users can be reduced when making connections via the connection guiders 310 and 330.

[0053] Specifically, the first connection guider 310 may be provided on one surface of the pack case 200, and the second connection guider 330 may be provided on the other surface of the pack case 200 adjacent to the one surface of the pack case 200.

[0054] In this embodiment, the first connection guider 310 and the second connection guider 330 are located on different sides of the pack case 200, but are arranged close to each other. This allows the worker or user to easily check the positions of the connection guiders 310, 330 more quickly by visual inspection when connecting the appropriate types of electrical components A and B, thereby further improving the work efficiency when installing, attaching, or connecting the electrical components.

[0055] Therefore, in the battery pack 10 according to this embodiment, it is possible to remarkably improve the ease of installation, mounting, and connection work for future inspections for connecting electrical components A and B of various connection types with a single product, and to remarkably improve the compatibility of the device.

[0056] Meanwhile, on each side of the pack case 200 where the first connection guider 310 and the second connection guider 330 are arranged, an identification mark portion for distinguishing the first connection guider 310 and the second connection guider 330 from each other may be provided. This is to prevent erroneous assembly during a connection operation by the worker or user.

[0057] FIG. 4 is a diagram for explaining a battery pack according to another embodiment of the present invention, FIG. 5 is a diagram for explaining the connection between the battery pack of FIG. 4 and electrical components of a first connection type, FIGS. 6 and 7 are diagrams for explaining the operation of the connection guide unit of the battery pack of FIG. 4, and FIG. 8 is a diagram for explaining the connection between the battery pack of FIG. 4 and electrical components of a second connection type.

[0058] The battery pack 20 according to this embodiment is substantially similar to the battery pack 10 according to the above-described embodiment, and therefore, a redundant description of the configuration that is substantially the same or similar to the above-described embodiment will be omitted, and the following description will focus on the differences from the above-described embodiment.

[0059] 4 to 8, the battery pack 20 may include a battery module 100, a pack case 200, and a connection guide unit 400.

[0060] The battery module 100 is substantially the same as or similar to the above-described embodiment, and therefore, a duplicated description will be omitted below.

[0061] The pack case 200 may be provided with a guide unit mounting portion 210 in which a connection guide unit 400 (described later) is arranged.

[0062] The connection guide unit 400 may include a first connection guider 410 and a second connection guider 430 .

[0063] At least one of the first connection guider 410 and the second connection guider 430 may be exposed to be connectable to the outside of the pack case 200 by a user's operation. Thus, in this embodiment, the user or worker can expose the first connection guider 410 or the second connection guider 430 to the outside of the pack case 200 according to a required connection type and connect it.

[0064] The connection guide unit 400 may include a shaft portion 450 .

[0065] The shaft portion 450 may be rotatably installed in the pack case 200. Specifically, the shaft portion 450 may be rotatably mounted to the guide unit mounting portion 210. The shaft portion 450 may be connected to the first connection guider 410 and the second connection guider 430.

[0066] In this embodiment, the worker or user can rotate the shaft portion 450 by performing an operation to guide the connection work via the first connection guider 410 and the second connection guider 430.

[0067] Specifically, the first connection guider 410 may be provided on one side of the shaft portion 450, and the second connection guider 430 may be provided on the other side of the shaft portion 450.

[0068] More specifically, the first connection guider 410 may be provided on one side of the shaft portion 450, and the second connection guider 430 may be provided on the other side of the shaft portion 450, which is the opposite side of the one side of the shaft portion 450.

[0069] The shaft portion 450 may be rotated according to the user's operation to expose the first connection guider 410 or the second connection guider 430 to the outside of the pack case 200 .

[0070] Here, if the first connection guider 410 is exposed to the outside of the pack case 200, the second connection guider 430 may be disposed inside the pack case 200, and if the second connection guider 430 is exposed to the outside of the pack case 200, the first connection guider 410 may be disposed inside the pack case 200.

[0071] As a result, in this embodiment, depending on the type of electrical components A, B of the connection type, only the connection guiders 410, 430 to be connected to the required electrical components A, B can be exposed to the outside of the pack case 200 and selectively connected to the electrical components A, B of the connection type to be connected.

[0072] The shaft portion 450 may be attached to the pack case 200 so as to be rotatable in either a clockwise direction or a counterclockwise direction. That is, the shaft portion 450 may be attached to the guide unit attachment portion 210 so as to be rotatable in a clockwise direction or a counterclockwise direction.

[0073] In this embodiment, the shaft part 450 may be provided to be rotatable in a counterclockwise direction as a user such as an operator or a user presses the shaft part 450. Here, the pressing of the shaft part 450 may be a part of one surface and a part of the other surface of the shaft part 450 where the first connection guider 410 and the second connection guider 430 are not disposed. For example, in FIG. 4, the pressing may be a lower surface on the left side (+X axis direction) and an upper surface on the right side (-X axis direction) of the shaft part 450 with respect to the rotation axis of the shaft part as the center.

[0074] Such rotation in one direction may be performed by pressing a portion of one surface of the shaft portion 450 on which the first connection guider 410 and the second connection guider 430 are not disposed and a portion of the other surface of the shaft portion 450 on which the first connection guider 410 and the second connection guider 430 are not disposed.

[0075] This is to prevent rotational movement from occurring when the portions of the shaft portion 450 where the first connection guider 410 and the second connection guider 430 are disposed are pressed. The first connection guider 410 and the second connection guider 430 perform a connection operation between the electric component A of the first connection type and the electric component B of the second connection type, respectively, and at this time, when pressed for connection, there is a risk that the shaft portion 450 will rotate and interfere with the connection operation.

[0076] Thus, in this embodiment, by rotating the connection guide unit 400 via the shaft portion 550, the first connection guider 410 or the second connection guider 430 can be exposed to the outside of the pack case 200 and selectively connected to electrical components A, B of the desired connection type.

[0077] Meanwhile, the first connection guider 410 and the second connection guider 430 may be configured to have shapes, patterns, or colors that are visually distinguishable from each other by the user. This makes it possible to more effectively prevent the occurrence of erroneous assembly by the user or worker during the connection of the first connection guider 410 and the second connection guider 430 to the electrical components A and B in this embodiment.

[0078] FIG. 9 is a view for explaining a battery pack according to still another embodiment of the present invention, and FIG. 10 is a view for explaining an operation of a fixing stopper of the battery pack of FIG.

[0079] The battery pack 30 according to this embodiment is substantially similar to the battery pack 20 according to the above-described embodiment, and therefore, a redundant description of the configuration that is substantially the same or similar to the above-described embodiment will be omitted, and the following description will focus on the differences from the above-described embodiment.

[0080] 9 and 10, the battery pack 30 may include a battery module 100, a pack case 200, and a connection guide unit 500.

[0081] The battery module 100 is substantially the same as or similar to the above-described embodiment, and therefore, a duplicated description will be omitted below.

[0082] The pack case 200 may include a stopper groove 250. The stopper groove 250 may be in communication with the guide unit mounting part 210. A fixed stopper 600, which will be described later, may be slidably mounted in the stopper groove 250.

[0083] The connection guide unit 500 may include a first connection guider 510 , a second connection guider 530 and a shaft portion 550 .

[0084] The first connection guider 510 and the second connection guider 530 are substantially the same as or similar to the first connection guider 410 and the second connection guider 430 of the above-mentioned embodiment, so that a duplicated description will be omitted below.

[0085] A stopper fitting portion 555 having a predetermined depth into which a fixed stopper 600 (to be described later) can be fitted may be formed in the shaft portion 550. Details of the stopper fitting portion 555 will be described in the related description section (to be described later).

[0086] The battery pack 30 may include a fixed stopper 600.

[0087] The fixing stopper 600 is provided on the pack case 200 and can fix the shaft portion 550. The fixing stopper 600 can restrict the movement of the shaft portion 550 and prevent the shaft portion 550 from shaking during the connection work of the first connection guider 510 or the second connection guider 530.

[0088] The fixed stopper 600 can be slid and coupled to the shaft portion 550 according to the user's operation, or can be detached from the shaft portion 550. In this way, when the shaft portion 550 needs to be rotated according to the user's operation, interference by the fixed stopper 600 can be prevented, and when the shaft portion 550 needs to be fixed, the movement of the shaft portion 550 can be restricted using the fixed stopper 600.

[0089] The fixed stopper 600 may include a stopper protrusion 610 and a stopper operating portion 630 .

[0090] The stopper protrusion 610 may be provided in the stopper groove 250. The stopper protrusion 610 may be fitted into the stopper fitting portion 555 of the shaft portion 550 or may be removed from the stopper fitting portion 555 while sliding vertically (in the Z-axis direction) along the stopper groove 250 according to the user's operation.

[0091] The stopper operating portion 630 may be connected to the stopper protrusion 610 and exposed to the outside of the pack case 200 to guide a user's operation of the fixed stopper 600 .

[0092] The worker, user, etc. can operate the stopper operating portion 630 to fit the stopper protrusion 610 into the stopper fitting portion 555 of the shaft portion 550 or to remove the stopper protrusion 610 from the stopper fitting portion 555 .

[0093] On the other hand, in this embodiment, since it is possible to fix the shaft portion 550 via the fixed stopper 600, it may also be possible for the shaft portion 550 to be configured to be rotatable in both the clockwise and counterclockwise directions.

[0094] In this manner, in this embodiment, when performing the connecting work of the first connection guider 510 or the second connection guider 530 via the fixing stopper 600, the shaft portion 550 can be fixed, thereby further improving the accuracy of the connecting work between each connection guider 510, 530 and the electrical components A, B.

[0095] FIG. 11 is a diagram for explaining a battery pack according to yet another embodiment of the present invention, FIG. 12 is a diagram for explaining the connection between the battery pack of FIG. 11 and electrical components of a first connection type, FIG. 13 is a diagram for explaining the operation of the connection guide unit of the battery pack of FIG. 11, and FIG. 14 is a diagram for explaining the connection between the battery pack of FIG. 11 and electrical components of a second connection type.

[0096] The battery pack 40 according to this embodiment is substantially similar to the battery pack 10 according to the above-described embodiment, and therefore, a redundant description of configurations that are substantially the same or similar to those of the above-described embodiment will be omitted, and the following description will focus on the differences from the above-described embodiment.

[0097] 11 to 14, the battery pack 40 may include a battery module 100, a pack case 200, and a connection guide unit 700.

[0098] The battery module 100 is substantially the same as or similar to the above-described embodiment, and therefore, a duplicated description will be omitted below.

[0099] The pack case 200 may include a sliding rail 270.

[0100] The slide rail 270 is for guiding the sliding of a slider 750 of a connection guide unit 700 (described later), and may be provided on one side of the pack case 200 .

[0101] The connection guide unit 700 may include a first connection guider 710 and a second connection guider 730 .

[0102] The first connection guider 710 may be provided on one surface of the pack case 200. The second connection guider 730 may be provided on one surface of the pack case 200 so as to be spaced a predetermined distance from the first connection guider 730. Specifically, the first connection guider 710 and the second connection guider 730 may be provided on one surface of the pack case 200 so as to be spaced a predetermined distance from each other along the up-down direction (Z-axis direction).

[0103] The connection guide unit 700 may include a slider 750 .

[0104] The slider 750 may be slidably installed in the pack case 200. Specifically, the slider 750 may be installed to be slidable in the up-down direction (Z-axis direction) along the slide rail 270.

[0105] The slider 750 can expose either the first connection guider 710 or the second connection guider 730 to the outside of the pack case 200 by sliding as described above.

[0106] As a result, in this embodiment, the slider 750 slides to expose either the first connection guider 710 or the second connection guider 730 so as to connect to the electrical components A and B of the connection type to be connected.

[0107] Specifically, the slider 750 may be configured to be slidable between a first position where the first connection guider 710 can be exposed and a second position where the second connection guider 730 can be exposed.

[0108] Here, the first position may refer to a position where the slider 750 covers the second connection guider 730 but is disposed below the first connection guider 710, and the second position may refer to a position where the slider 750 covers the first connection guider 710 but is disposed above the second connection guider 730.

[0109] Thus, in this embodiment, by sliding via the slider 750 of the connection guide unit 700, the first connection guider 710 or the second connection guider 730 can be exposed to the outside of the pack case 200, and selectively connected to electrical components A, B of the desired connection type.
