Embodiments for Carrying Out the Invention

[0011] Hereinafter, referring to the accompanying drawings, preferred embodiments of the present disclosure will be described in detail so that those having ordinary knowledge in the technical field to which the present disclosure pertains can easily implement it. However, the present disclosure can be realized in various different forms and is not limited or restricted by the following embodiments.

[0012] For the purpose of clearly explaining this disclosure, detailed descriptions of relevant prior art that are irrelevant to the explanation or that could obscure the gist of this disclosure have been omitted. In this specification, when assigning reference numerals to components of each drawing, the same or similar reference numerals are used throughout the specification for components that are the same or similar.

[0013] Furthermore, terms and words used in this specification and in the claims should not be interpreted in a manner limited to their ordinary or dictionary meanings, but rather in a manner consistent with the technical idea of ​​this disclosure, in accordance with the principle that inventors may define the concepts of terms as appropriate to best describe their inventions.

[0014] Figure 1 is an exploded perspective view of an energy storage system according to one embodiment of the present disclosure.

[0015] The energy storage system 1 may include a battery control unit 2. The battery control unit 2 can perform overall control of the energy storage system 1.

[0016] The energy storage system 1 may include a battery module assembly 3. The battery module assembly 3 may be an assembly that has a battery module or battery built inside. Multiple battery module assemblies 3 may be provided.

[0017] The energy storage system 1 may include a bottom plate assembly 4. The bottom plate assembly 4 can form the lower outer surface of the energy storage system 1.

[0018] The energy storage system 1 can be configured such that a battery module assembly 3 is stacked on a bottom plate assembly 4, and a battery control unit 2 is stacked on the battery module assembly 3.

[0019] The energy storage system 1 may include a first connector 10 and a second connector 20. For example, the first connector 10 and the second connector 20 can electrically connect a stacked bottom plate assembly 4, a battery module assembly 3, and a battery control unit 2.

[0020] Specifically, for example, the first connector 10 and the second connector 20 can be located on the top and bottom of each battery module assembly 3. Here, the first connector 10 can be located on the bottom plate assembly 4, and the second connector 20 can be located on the battery control unit 2. However, the disclosure is not limited thereto.

[0021] As in the example above, by providing the energy storage system 1, the bottom plate assembly 4, the battery module assembly 3, and the battery control unit 2 can be electrically connected by the first connector 10 and the second connector 20.

[0022] Figure 2 is a perspective view showing the assembly of a battery module assembly according to one embodiment of the present disclosure, and Figure 3 is a cross-sectional view showing the battery module assembly according to one embodiment of the present disclosure in a temporary mounting position.

[0023] The energy storage system 1 may include multiple battery module assemblies 3. For the sake of explanation, of the two battery module assemblies 3, the one located at the bottom can be defined as the first battery module assembly, and the one located at the top can be defined as the second battery module assembly.

[0024] For example, the energy storage system 1 may include a first battery module assembly and a second battery module assembly mounted on the first battery module assembly.

[0025] The first connector 10 can be attached to the first connector mounting portion 3-1 of the first battery module assembly. The second connector 20 can be attached to the second connector mounting portion 3-2 of the second battery module assembly.

[0026] The first battery module assembly may include a module guide 3-3. The module guide 3-3 may be provided to guide mounting with the second battery module assembly.

[0027] Multiple module guides 3-3 can be provided.

[0028] To illustrate with a specific example, the first battery module assembly can be in the form of a rectangular parallelepiped. Here, the module guides 3-3 can be formed on two or more edges of the first battery module assembly when viewed from above.

[0029] Module guides 3-3 can be formed on the edge of the first battery module assembly. Module guides 3-3 can be provided so as to extend upward from the edge of the first battery module assembly.

[0030] The second battery module assembly may include a guide mounting portion 3-5. The guide mounting portion 3-5 may be provided to which the module guide 3-3 is attached.

[0031] Multiple guide mounting sections 3-5 can be provided. For example, multiple module guides 3-3 may be provided so as to extend upward from the edge of the first battery module assembly, and the second battery module assembly may include guide mounting sections 3-5 to which the module guides 3-3 are attached.

[0032] The battery module assembly 3 may be provided with both a module guide 3-3 and a guide mounting portion 3-5. For example, the module guide 3-3 may be formed on the upper edge of the battery module assembly 3, and the guide mounting portion 3-5 may be formed on the lower edge. In this case, stacking of battery module assemblies 3 of the same form can be easily performed.

[0033] The formation positions of the module guide 3-3 and the guide mounting portion 3-5 are not limited to the positions described above.

[0034] The first battery module assembly may include a first connector 10 that is exposed upwards so as to be electrically connected to the second battery module assembly.

[0035] The second battery module assembly may include a second connector 20 that is exposed downwards so as to be electrically connected to the first battery module assembly.

[0036] The first connector 10 and the second connector 20 can be provided to be electrically connected.

[0037] The first connector 10 and the second connector 20 can be positioned so as to be separated by a predetermined distance L1 when the module guide 3-3 is temporarily attached to the guide mounting portion 3-5. The predetermined distance L1 may be in the range of 4 mm to 5 mm, but is not limited thereto.

[0038] As described above, when the module guide 3-3 is temporarily attached to the guide mounting portion 3-5, the first connector 10 and the second connector 20 are separated by a predetermined distance L1, thereby preventing damage to the first connector 10 and the second connector 20 due to collision.

[0039] Figure 4 is a cross-sectional view showing a point in time during the process of terminal coupling according to one embodiment of the present disclosure, and Figure 5 is a cross-sectional view showing the terminals coupled according to one embodiment of the present disclosure.

[0040] The first connector 10 and the second connector 20 can be attached after the temporary mounting by the weight of the second battery module assembly. For example, after the temporary mounting, the first connector 10 and the second connector 20 can be fastened by the load of the second battery module assembly that is temporarily mounted on the first battery module assembly.

[0041] The first connector 10 may include a first high-voltage terminal 110 and a first low-voltage terminal 120.

[0042] The second connector 20 may include a second high-voltage terminal 210 and a second low-voltage terminal 220.

[0043] When the first high-voltage terminal 110 and the second high-voltage terminal 210 are in contact, the first low-voltage terminal 120 and the second low-voltage terminal 220 can be separated by a predetermined distance L2. The predetermined distance L2 separated by the first low-voltage terminal 120 and the second low-voltage terminal 220 can be in the range of 1 mm to 1.5 mm, but is not limited thereto.

[0044] The first high-voltage terminal 110 and the second high-voltage terminal 210 may each have a larger radius than the first low-voltage terminal 120 and the second low-voltage terminal 220, respectively.

[0045] The first high-voltage terminal 110 and the second high-voltage terminal 210 may have greater rigidity than the first low-voltage terminal 120 and the second low-voltage terminal 220, respectively.

[0046] The first high-voltage terminal 110 may be inserted into the second high-voltage terminal 210 before the second low-voltage terminal 220 is inserted into the first low-voltage terminal 120.

[0047] As described above, since the first high-voltage terminal 110 is inserted into the second high-voltage terminal 210 before the second low-voltage terminal 220 is inserted into the first low-voltage terminal 120, the high-voltage terminals, which have relatively greater rigidity and radius, can be connected first, and the low-voltage terminals, which have relatively weaker rigidity, can be connected later. This prevents damage to the terminals. In addition, the insertion of the high-voltage terminals first can guide the low-voltage terminals.

[0048] The overlap length L4 when the first high-voltage terminal 110 is fully inserted into the second high-voltage terminal 210 may be in the range of 4 mm to 5 mm. Similarly, the overlap length L3 when the first low-voltage terminal 120 is fully inserted into the second low-voltage terminal 220 may be in the range of 3.5 mm to 4 mm. The above numerical ranges are illustrative and not limiting.

[0108] The second connector housing 200 may include the second body portion 230.

[0109] The second connector housing 200 may include a second connecting portion 240. The second connecting portion 240 may be formed by recessing from the second body portion 230 in the insertion direction of the first connecting portion 150, so as to accommodate the first connecting portion 150.

[0110] The second connection portion 240 may include a second high-voltage connection portion 241 and a second low-voltage connection portion 242. The second high-voltage connection portion 241 and the second low-voltage connection portion 242 may each have a recessed form in the second body portion 230 in a form corresponding to the first high-voltage connection portion 151 and the first low-voltage connection portion 152.

[0111] An inclined portion 250 can be formed on the edge of the second connecting portion 240, which is provided at an angle so that the first connecting portion 150 can slide.

[0112] The inclined portion 250 can extend from the edge of the second connecting portion 240 so as to be inclined with respect to the insertion direction (or the coupling axis Z-Z') in a direction away from the coupling axis Z-Z' in the insertion direction.

[0113] The second high-voltage connection portion 241 and the second low-voltage connection portion 242 can be provided inside the inclined portion 250 when viewed along the insertion direction (or coupling axis Z-Z').

[0114] Figure 22 is a conceptual diagram showing the sliding of the first and second connectors according to one embodiment of the present disclosure. The above-described embodiments can be applied identically or similarly to this embodiment.

[0115] When the second connector 20 is attached to the first connector 10, it can be attached by the weight of the battery module assembly 3 described above.

[0116] When the battery module assembly 3 is temporarily installed and the second connector 20 is attached to the first connector 10 by its own weight, the first connection portion 150 of the first connector 10 can be accurately inserted into the second connection portion 240 of the second connector 20 without collision or contact.

[0117] In the temporary mounting state, if the second connector 20 is attached to the first connector 10 by the weight of the battery module assembly 3, the first connection portion 150 of the first connector 10 may collide with or come into contact with the second connection portion 240 of the second connector 20. In this case, the first connection portion 150 may collide with or come into contact with the inclined portion 250.

[0118] The first connecting portion 150 can be guided into the second connector 20 by the inclination of the inclined portion 250. For example, when viewed from above along the coupling axis Z-Z', the first connecting portion 150 can contact the left upper end LH, the right upper end RH, the left lower end LL, and the right lower end RL. Inclined surfaces are formed at the left upper end LH, the right upper end RH, the left lower end LL, and the right lower end RL, allowing the connecting portion 150 to be guided into the second connector 20.

[0119] The above explanation uses the upper left end LH, upper right end RH, lower left end LL, and lower right end RL as examples, but the same can be applied to any point on the inclined section 250.

[0120] Since the first connecting portion 150 has rounded portions 151-1 and 152-1 formed thereon, it can be guided more effectively for insertion with respect to the inclined portion 250 while minimizing damage and wear.

[0121] Figure 23 is a perspective view showing a holding member attached to a first connector housing according to one embodiment of the present disclosure, Figure 24 is a conceptual diagram showing a holding member attached to a first connector housing according to one embodiment of the present disclosure, and Figure 25 is a partially enlarged view showing a holding member attached to a first connector housing according to one embodiment of the present disclosure. The above-described embodiments can be applied identically or similarly to these embodiments.

[0122] The first connector 10 may include a holding member 170.

[0123] The holding member 170 can be attached to the first body portion 130 so that the first connector 10 can move within a predetermined range. For example, the holding member 170 can be attached to the first body portion 130 so that the first connector 10 can move within a predetermined range when the second connector 20 is attached to the first connector 10. Specifically, the holding member 170 can be attached to the holding member mounting portion 131 of the first body portion 130.

[0124] The holding member 170 can movably connect the first body portion 130 to the battery module assembly 3 (or the first connector mounting portion 3-1) to which the first body portion 130 is attached.

[0125] The first body portion 130 may be provided with a hold member mounting portion 131 having a through hole formed therein, to which a hold member 170 can be attached. The through hole formed in the hold member mounting portion 131 may have a hemispherical shape. The hemispherical shape can be used to ensure that the distance between the first portion 172 of the hold member 170 and the hold member mounting portion 131 is a predetermined distance apart.

[0126] The holding member 170 can be partially in contact with the holding member mounting portion 131, and partially separated from the holding member mounting portion 131.

[0127] The holding member 170 may include a head portion 171. For example, the head portion 171 may be a part with a diameter larger than the through hole that is placed on the holding member mounting portion 131.

[0128] The holding member 170 may include a first portion 172. For example, the first portion 172 may be a portion connected to the head portion 171 and spaced a predetermined distance L5 apart from the holding member mounting portion 131. The first portion 172 may also have a length corresponding to the thickness of the first body portion 130.

[0129] The holding member 170 may include a second portion 173. For example, the second portion 173 may be connected to the first portion 172 and have a smaller outer diameter than the first portion 172. However, the second portion 173 does not necessarily have to have a smaller outer diameter than the first portion 172 and is not particularly limited. The second portion 173 may be coupled to the battery module assembly 3 (or the first connector mounting portion 3-1).

[0130] When the second connector 20 is mounted on the first connector 10, if the first connector 10 is movable within a predetermined range, damage and wear can be minimized, and the mounting of the second connector 20 on the first connector 10 can be guided. In other words, the first connector 10 can move freely by a predetermined distance L5, and the connecting portion 150 can be effectively guided into the inside of the second connector 20.

[0131] Figure 26 is an exploded perspective view showing a first high-voltage terminal block and a first high-voltage terminal according to one embodiment of the present disclosure. Figure 27 is a perspective view showing the first high-voltage terminal block and the first high-voltage terminal coupled together according to one embodiment of the present disclosure. The above-described embodiments can be applied identically or similarly to these embodiments.

[0132] The first high-voltage terminal block 111 may include the first block 310. For example, the first block 310 may surround one side of the first high-voltage terminal 110.

[0133] The first high-voltage terminal block 111 may include a second block 320. For example, the second block 320 may be configured to connect with the first block 310 and surround the other side of the first high-voltage terminal 110.

[0134] The first high-voltage terminal block 111 can also enclose a portion of the wire line connected to the first high-voltage terminal 110.

[0135] The first high-voltage terminal 110 may include a groove 110-2. For example, the groove 110-2 can be formed by a recess in a part of the first high-voltage terminal 110.

[0136] The first high-voltage terminal block 111 may include a locking portion 312. The locking portion 312 can be provided so that the end of the first high-voltage terminal block 111 on the first high-voltage terminal 110 side is locked into the groove portion 110-2.

[0137] The first block 310 may include a first joint 311 for interference fit.

[0138] The second block 320 may include a second joint 321 for interference fit.

[0139] The first coupling portion 311 and the second coupling portion 321 are joined by interference fit, and the first high-voltage terminal block 111 can be attached to the first high-voltage terminal 110.

[0140] The first high-voltage terminal 110 may include a projection 110-1. The projection 110-1 can project in such a way that it restricts the longitudinal movement of the first high-voltage terminal 110 of the first high-voltage terminal block 111.

[0141] Since the first high-voltage terminal block 111 includes a projection 111-1 that protrudes toward the first connector housing 100, its movement relative to the first connector housing 100 can be restricted.

[0142] The first connector housing 100 can support the protrusion 111-1 when a force is applied to the first high-voltage terminal block 111 in the opposite direction to the insertion direction, thereby restricting the movement of the first high-voltage terminal block 111.

[0143] Figure 28 is a perspective view showing the terminal block mounting portion of a first connector housing according to one embodiment of the present disclosure; Figure 29 is a bottom view showing the terminal block mounting portion of a first connector according to one embodiment of the present disclosure; Figure 30 is a conceptual diagram showing how the first connector is attached to the first connector mounting portion according to one embodiment of the present disclosure; Figure 31 is a bottom view showing the terminal block mounting portion of a second connector according to one embodiment of the present disclosure; and Figure 32 is a conceptual diagram showing how the second connector is attached to the second connector mounting portion according to one embodiment of the present disclosure. The above-described embodiments can be applied identically or similarly to these embodiments.

[0144] The above-described embodiments can be applied identically or similarly to these embodiments.

[0145] As described above, the connectors 10 and 20 may include body portions 130 and 230, connection portions 150 and 240 provided on one side of the body portions 130 and 230 to be electrically connected to the outside, and mounting portions 140 and 201 provided on the other side of the body portions 130 and 230 to be open for insertion of terminals 110, 120, 210, and 220, and to be attached to the battery module assembly 3.

[0146] Mounting portions 140 and 201 are mounting portions that serve as terminal block mounting portions and may also be mounting portions that are attached to the battery module assembly 3 (or connector mounting portions 3-1 and 3-2).

[0147] The mounting portions 140 and 201 can be formed asymmetrically.

[0148] For example, the mounting portion 140 may include a projection 141-4 that protrudes from one edge in a direction transverse to the edge. Specifically, the projection 141-4 may, but is not limited to, extend perpendicular to the edge.

[0149] Another example is that the mounting portion 201 may be provided with a rounded portion. Specifically, the mounting portion 201 may be provided with a rounded portion on only one edge.

[0150] The asymmetrical formation of mounting portions 140 and 201 prevents incorrect assembly; in the event of incorrect assembly, the connector mounting portions 3-1 and 3-2 will be attached to the mounting hole 3-4 in a direction other than the direction specified.

[0151] The above-described configurations of the mounting portions 140 and 201 are illustrative and can be designed in various ways to prevent misassembly when they are asymmetrical.

[0152] Although this disclosure has been described above with reference to limited embodiments and drawings, it is not limited thereto, and various implementations are possible within the equivalent scope of the technical concept of this disclosure and the claims set forth below by persons with ordinary skill in the art to which this disclosure pertains.
