[0058] Reference below Figure 1-Figure 13 An integrated plug-in component 1 and an energy storage system 100 according to an embodiment of the present invention are described.

[0059] like Figure 1 According to the integrated plug 1 of the embodiment of the present application, the integrated plug 1 is pluggably arranged on the electric module 10, including a board body and an electrical connection component, the electrical connection component is arranged on the board body, and the electrical connection component includes: a positive male plug, a negative male plug and a connection part 40, the positive male plug and the negative male plug are respectively suitable for being electrically connected to the positive and negative poles of the electric module 10, and the connection part 40 is used for being electrically connected to the outside.

[0060] It is understandable that the electric module 10 of the prior art is mainly connected by setting up an independent connector, connecting through a wiring harness, wiring and tying the wires, and then locking the protective cover. The installation site operation is complicated, and too much wiring is prone to errors; if it is a parallel structure, the positive and negative power leads of each battery module require two connectors each. When the parallel connection is changed to a series connection, the external wiring structure cannot be realized, and the shell structure needs to be redesigned, and the connector and wiring harness structure need to be rearranged; if the parallel connection is changed to a series connection without changing the structure, it is very easy to make mistakes when using the original connector to connect the system, resulting in system failure, and in severe cases, there will be a risk of thermal runaway; at the same time, the prior art will use more power terminal structures in parallel structures and external wiring methods, which is costly and will also occupy panel space, resulting in inconvenient operation or reducing the energy ratio when the panel is enlarged.

[0061] Based on this, the present application proposes an integrated plug component 1, which integrates an electrical connection component in a board body, and the board body can be formed as a decorative panel at one end or one side of the electrical module 10. When the integrated plug component 1 is assembled on the electrical module 10, the electrical connection between the electrical connection component and the electrical module 10 can be achieved, and the electrical connection between the electrical module 10 and the outside can be achieved through the connection part 40 of the electrical connection component.

[0062] It should be pointed out that the electrical connection between the electrical module 10 and the outside can be to use the connection part 40 as the output end to transfer the electrical energy of the electrical module 10 to the outside, that is, to connect the load through the electrical connection part 40, or to connect in series or in parallel with other surrounding electrical modules 10 through the connection part 40.

[0063] According to the integrated plug component 1 of the embodiment of the present application, by integrating the electrical connection component in the board body, the electrical connection between the electrical module 10 and the electrical connection component can be achieved while completing the assembly of the integrated plug component 1 on the electrical module 10, thereby reducing the wiring difficulty, thereby reducing the probability of errors, and improving safety and reliability. In addition, the electrical connection between the electrical module 10 and the outside can be achieved through the connecting portion 40, thereby reducing the difficulty of electrical connection between the electrical module 10 and the outside and improving ease of use.

[0064] According to some embodiments of the present application, the electrical module 10 has a positive female plug 11 and a negative female plug 12 , the positive male plug is suitable for being electrically connected to the positive female plug 11 , and the negative male plug is suitable for being electrically connected to the negative female plug 12 .

[0065] That is to say, the electrical module 10 and the electrical connection component are electrically connected through the plug-in form of a female plug and a male plug, and a female plug is formed on the electrical module 10. During the process of assembling the male plug on the electrical connection component to the electrical module 10 along with the board body, the male plug is plugged with the female plug along the assembly direction to achieve electrical connection coordination, which can improve the stability and reliability of the electrical connection, reduce the difficulty of transferring the electrical connection between the electrical connection component and the electrical module 10, and improve the convenience of assembly.

[0066] like Figure 4 and Figure 5 As shown, the positive male plug and the negative male plug both include: a male plug body 501 and a male plug conductor 502, and the positive female plug 11 and the negative female plug 12 both include: a female plug body 401 and a female plug conductor 402, the male plug body 501 is plugged into the female plug body 401, and the male plug conductor 502 is electrically connected to the female plug conductor 402.

[0067] Specifically, a clamping plate 601 is provided on the male plug body 501 or the female plug body 401. The clamping plates 601 are elastic and are arranged opposite to each other. A clamping space is defined between the two clamping plates 601. The male plug conductor 502 and the female plug conductor 402 can contact and cooperate in the clamping space, and the male plug conductor 502 and the female plug conductor 402 can be clamped by the clamping plate 601, that is, the two can be elastically pushed against each other so that the two can fit together and be electrically connected.

[0068] In this way, the electrical connection stability between the electrical connection component and the electrical module 10 can be improved, the probability of poor contact can be reduced, and safety can be improved.

[0069] Furthermore, a connecting plate 602 is provided on the male plug body 501 , and the connecting plate 602 is located at the end of the male plug body 501 facing the female plug body 401 , and a limiting portion 603 cooperating with the connecting plate 602 is provided at one end of the female plug body 401 away from the male plug body 501 .

[0070] That is to say, the end of the connecting plate 602 may be provided with a buckle, or a buckle hole, and the corresponding limiting portion 603 is formed as a buckle slot or a buckle, so as to achieve a stable and reliable connection between the male plug and the female plug through the snap-fit ​​cooperation between the connecting plate 602 and the limiting portion 603, thereby further improving the connection stability and reliability.

[0071] like Figure 4 and Figure 5 As shown, a sealing member 604 is provided on the female plug body 401 to seal with the male plug body 501 .

[0072] Thus, the sealing member 604 can be used to achieve sealing cooperation between the male plug and the female plug, thereby improving the sealing performance, reducing the probability of a circuit break or short circuit, and improving the safety and reliability of the energy storage system 100 .

[0073] It should be pointed out that at least part of the connecting part 40 is connected to the positive male plug or the negative male plug, and the positive male plug or the negative male plug is located at the end or middle area of ​​the connecting part 40, and at least one end of the connecting part 40 is configured as a lead-out end 41, which is used to electrically connect with an external plug-in.

[0074] That is to say, both ends of a portion of the connecting portion 40 are formed as lead-out ends 41 to facilitate electrical connection across the electrical module 10, one end of a portion of the connecting ends is connected to the negative male plug or the positive male plug, and the other end is formed as a lead-out end 41 to facilitate connection of the lead-out end 41 to the outside, and in an embodiment where the connecting portion 40 has two lead-out ends 41, one lead-out end 41 is configured as a lead-out male end, and one lead-out end 41 is configured as a lead-out female end, and the lead-out male end of the connecting portion 40 can be plugged into and matched with the lead-out female end of the other connecting portion 40.

[0075] like Figure 6 and Figure 7 As shown, further, the lead-out male end includes: a contact portion 411 and a first cover body 412 surrounding the contact portion 411, a via hole is provided on the first cover body 412, and the lead-out female end passes through the via hole and contacts the contact portion 411 for electrical connection.

[0076] Specifically, the contact portion 411 is suitable for being electrically connected to the lead-out female end, and the lead-out female end is constructed as an exposed end on the connecting portion 40, and the first cover body 412 can be constructed as a plastic-coated structure and formed as a plastic groove, and the groove is formed as an accommodating cavity. The contact portion 411 contacts the lead-out female end for electrical connection, and the plastic groove can elastically cover the lead-out female end and the contact portion 411, thereby improving the stability and reliability of the contact electrical connection.

[0077] Further, the board body is formed as a circuit board, and the connecting part 40, the positive male plug and the negative male plug are all integrated into the circuit board, or the board body is formed as a protective cover of the electric module 10, and the connecting part 40, the positive male plug and the negative male plug are all arranged in the protective cover.

[0078] That is to say, in some embodiments, the integrated plug-in component 1 is constructed as a circuit board, and the circuit board can be quickly installed on the electrical module 10, thereby improving the convenience of disassembly and reducing the difficulty of maintenance. In other embodiments, the board body is formed as a protective cover, and the electrical connection component can be integrated in the protective cover, which can not only reduce the difficulty of assembly, but also protect the electrical connection between the electrical connection component and the electrical module 10, further improving safety and reliability.

[0079] like Figure 1 , Figure 2 and Figure 3 As shown, the energy storage system 100 according to the embodiment of the present application includes: an electric module 10 and an integrated plug 1, the integrated plug 1 is constructed as a series plug 20 or a parallel plug 30, and the series plug 20 and the parallel plug 30 are selectively arranged and arranged at the end of the electric module 10, and the positive male plug and the negative male plug of the integrated plug 1 are respectively suitable for being electrically connected to the positive female plug 11 and the negative female plug 12 of the electric module 10.

[0080] Therefore, the electric module 10 can be connected in series or in parallel with other external electric modules 10 by selecting either the series plug-in component 20 or the parallel plug-in component 30 .

[0081] Furthermore, there are multiple electrical modules 10, and the electrical modules 10 are stacked along a first direction. The series plug-in component 20 can be optionally arranged on the electrical module 10 and is suitable for connecting multiple electrical modules 10 in series. The parallel plug-in component 30 can be optionally arranged on the electrical module 10 and is suitable for connecting multiple electrical modules 10 in parallel.

[0082] It should be pointed out that the first direction may be any one of a height direction, a length direction or a width direction, and this application does not make any specific limitation.

[0083] It is understandable that the defects of the prior art are mainly that the electrical connection is led out by setting up independent connectors separately, connected through wiring harnesses, and then the protective cover is locked. The installation site operation is complicated, and too much wiring is prone to errors; if it is a parallel structure, the positive and negative power leads of each battery module require two connectors each. When the parallel connection is changed to series connection, the external wiring structure cannot be realized, and the shell structure needs to be redesigned, and the connector and wiring harness structure need to be rearranged; if the parallel connection is changed to series connection without changing the structure, it is very easy to make mistakes when using the original connector to connect, resulting in system failure, and in severe cases, there will be a risk of thermal runaway; at the same time, the prior art will use more power terminal structures in parallel structures and external wiring methods, which is costly and will also occupy panel space, resulting in inconvenient operation or reducing the energy ratio when the panel is enlarged.

[0084] Based on this, the present application stacks multiple electrical modules 10 in a first direction, and when the energy storage system 100 is constructed as a series structure, the multiple electrical modules 10 can be electrically connected through a series plug-in component 20, and when the energy storage system 100 is constructed as a parallel structure, the multiple electrical modules 10 can be electrically connected through a parallel plug-in component 30.

[0085] That is to say, either the series plug 20 or the parallel plug 30 is set to construct the energy storage system 100 into a series structure or a parallel structure according to usage requirements. The series plug 20 can be integrated with a series wiring harness structure for connecting multiple electrical modules 10 in series, and the parallel plug 30 can be integrated with a parallel wiring harness structure for connecting multiple electrical modules 10 in parallel.

[0086] In this way, multiple electric modules 10 can be connected in series or in parallel without the need for separately arranged connectors, power terminals, etc., and there is no need for wiring and tying. The operation at the installation site is simpler, the number of wiring harnesses is smaller, and the wiring harness routing is clearer, which can reduce the probability of wiring errors. The series structure energy storage system 100 and the parallel structure energy storage system 100 can respectively use a series plug-in 20 mixed with a parallel plug-in 30, without the need to change the wiring harness between parallel and series connection, which can also reduce the probability of wiring errors and the risk of thermal runaway. The number of connectors and power terminals can be reduced to reduce costs, reduce the space occupied by the panel space of the energy storage system 100, improve operational convenience, and improve the energy density of the energy storage system 100.

[0087] It should be noted that the electric module 10 can be constructed as a battery pack, or a battery pack integrated with a control box, or a control box, or a transformer box. That is to say, the energy storage system 100 can have one electric module 10, and the electric module 10 is integrated with a battery pack, a control box, or a battery pack and a transformer box. The energy storage system 100 can also have multiple electric modules 10, at least one of which is constructed as a battery pack, and one of which is constructed as an integration of a battery pack and a control box; at least one of which is constructed as a battery pack, one of which is constructed as a control box, and one of which is constructed as a transformer box.

[0088] Exemplarily, the electrical module 10 includes: a first electrical module 101, a second electrical module 102 and a third electrical module 103, the second electrical module 102 is stacked on the first electrical module 101 along a first direction, the third electrical module 103 is stacked on the first electrical module 101 along a first direction, and the energy storage system 100 is constructed as a series structure, and the series plug-in 20 includes: a first bottom protective cover 23 arranged on the first electrical module 101, a first middle protective cover 22 arranged on the second electrical module 102, and a first top protective cover 21 arranged on the third electrical module 103; or the energy storage system 100 is constructed as a parallel structure, and the parallel plug-in 30 includes: a second bottom protective cover 33 arranged on the first electrical module 101, a second middle protective cover 32 arranged on the second electrical module 102, and a second top protective cover 31 arranged on the third electrical module 103.

[0089] Among them, the first electrical module 101 is constructed as a battery pack, the second electrical module 102 is also constructed as a battery pack, and the third electrical module 103 is constructed as a battery pack integrated with a control box, or the third electrical module 103 is constructed as a control box, and at the same time, the first bottom protective cover 23, the first middle protective cover 22 and the first top protective cover 21 realize the series electrical connection of the three electrical modules 10; or the second bottom protective cover 33, the second middle protective cover 32 and the second top protective cover 31 realize the parallel electrical connection of the three electrical modules 10.

[0090] It should be pointed out that when the parallel structure needs to be switched to the series structure, a quick change can be achieved by simply changing the series plug-in 20 to a parallel plug-in 30. Of course, the internal functions of multiple electrical modules 10 need to be compatible with series-parallel switching or updated and redesigned, without the need to redesign the housing, protective cover and external wiring of the electrical module 10; the lead-out terminals 41 (female plugs) on the electrical module 10 can be arranged according to design requirements, and can be used in a standardized manner after the design is finalized. The wiring is simple, and there is no need for routing and tying wires. It can effectively prevent errors, reduce the probability of errors, reduce the probability of thermal runaway and failure of the energy storage system 100, improve safety, and save wiring and tying time.

[0091] It is understandable that adjacent electrical modules 10 can be quickly disassembled through structures such as plug-in structures, snap-on structures or interlocking sheets, which further reduces the difficulty of assembly and improves the assembly efficiency and ease of use of the energy storage system 100.

[0092] According to the energy storage system 100 of the embodiment of the present application, by providing a series plug-in 20 and a parallel plug-in 30, and either the series plug-in 20 or the parallel plug-in 30 is selectively provided, a rapid change between the parallel structure and the series structure can be achieved without redesigning the protective cover and the external wiring harness, and standardized use can be achieved without separately providing routing and binding wires, which can improve assembly efficiency, effectively prevent errors, and improve the working stability and safety of the energy storage system 100.

[0104] In this way, the electrical connection between the plurality of electrical modules 10 is achieved by integrating the second positive male plug 301 and the second negative male plug 302 in the parallel plug 30 , which makes the electrical connection easier and improves the assembly efficiency.

At this time, the second bottom-level protective cover 33 has the same structure as the second intermediate protective cover 32, and the universal setting of at least part of the parallel plug-in components 30 can be realized. In addition, for the subsequent expansion of the parallel energy storage system 100, the ninth wiring harness and the tenth wiring harness may not be arranged in the second bottom-level protective cover 33, which can reduce the amount of wiring harnesses and reduce costs, but is not conducive to the later expansion of the energy storage system 100.

[0117] like Fig.13 As shown, further, when the electrical modules 10 are connected in parallel, a parallel protection sleeve 90 is provided on the lead-out female end of the connecting portion 40 away from the second positive male plug 301 and the second negative male plug 302 in the parallel plug 30 at one end of the first direction.

[0121] Combination Figures 8 to 13 As shown, in some embodiments, the electrical modules 10 have a wiring harness female plug 13, and the serial plug 20 and the parallel plug 30 are both provided with a signal wiring harness 50, and the signal wiring harness 50 is signal-connected to the signal female plug.

There may be one or more harness female plugs 13 on each electrical module 10, and signal connection can be achieved between multiple electrical modules 10 through the signal harness 50. The electrical module 10 that is integrated with a controller or formed as a controller only needs to be provided with one harness female plug 13, and the electrical module 10 located at the end may also only be provided with one harness female plug 13.

[0128] Specifically, the quick-release structure may be a snap-on structure, a plug-in structure, or a magnetic structure.

[0129] Therefore, after the stacking and wiring is completed, the electrical module 10 does not need to be fastened by fasteners such as bolts, but can be connected by a magnetic attraction plus a male plug and a female plug-in structure, which can reduce the time for operating other locking structures and has a neater appearance.

[0130] It should be pointed out that the connection part 40 can be an aluminum bar, a conductor or a wiring harness, as long as it meets the electrical and thermal design requirements, and this application does not make any further limitations.

[0131] like Figure 1 As shown, according to some embodiments of the present application, the energy storage system 100 further includes: a base 70 , which is disposed at one end of the energy storage system 100 in the first direction and fixed to the electric module 10 .

[0132] Therefore, by providing the base 70 , the energy storage system 100 can obtain a larger ground clearance, so as to reduce the probability of water entering the electric module 10 located below, and improve the stability and reliability of the energy storage system 100 .

[0133] Other structures and operations of the energy storage system 100 according to the embodiment of the present invention are known to ordinary technicians in the field and will not be described here in detail.
