[0053] The integrated plug-in 1 and the energy storage system 100 according to embodiments of the present application are described below with reference to FIGS. 1-13.

[0054] As shown in FIG. 1, the integrated plug-in 1 according to embodiments of the present application is pluggably arranged in the electrical module 10, and includes a plate body and an electrical connection assembly arranged in the plate body. The electrical connection assembly includes a positive male plug, a negative male plug, and a connecting portion 40. The positive male plug and the negative male plug are adapted to be electrically connected with the positive and negative poles of the electrical module 10, respectively. The connecting portion 40 is used to be electrically connected with an external device.

[0055] It can be understood that the electrical module 10 in the prior art mainly leads out the electrical connection through a separately arranged independent connector, connects through a wire harness, and then locks a protective cover after wiring. The operation at the installation site is complex, and too many connections are prone to errors. If it is a parallel structure, each battery module needs two connectors for the positive and negative power leads. In the case of changing the parallel structure to a series structure, the external connection structure cannot be realized, and the shell structure needs to be redesigned, and the connectors and the wire harness structure also need to be rearranged. If the parallel structure is changed to a series structure without changing the structure, the original connector is used for connection, which is prone to errors and causes the system to fail. In severe cases, there is a risk of thermal runaway. At the same time, the prior art uses more power terminal structures in the parallel structure and uses external connection, which is high in cost and occupies panel space, resulting in inconvenient operation or increased panel size and reduced energy ratio.

[0056] Based on this, the present application proposes an integrated plug-in 1, which integrates the electrical connection assembly in the plate body. The plate body can be formed as a decorative plate at one end or one side of the electrical module 10. The electrical connection of the electrical connection assembly with the electrical module 10 can be realized while completing the assembly of the integrated plug-in 1 on the electrical module 10. The electrical connection of the electrical module 10 with the external device can be realized through the connecting portion 40 of the electrical connection assembly.

[0057] It should be noted that the electrical connection of the electrical module 10 with the external device can be realized by taking the connecting portion 40 as an output end to transmit the electrical energy of the electrical module 10 to the outside, i.e., connecting the load through the electrical connection portion 40, or connecting in series or parallel with other electrical modules 10 around the connecting portion 40.

[0058] According to the integrated plug-in 1 of the present application, the electrical connection assembly is integrated in the plate body. The electrical connection of the electrical module 10 with the electrical connection assembly can be realized while completing the assembly of the integrated plug-in 1 on the electrical module 10. The wiring difficulty is reduced to reduce the error probability and improve the safety and reliability. The electrical connection of the electrical module 10 with the external device can be realized through the connecting portion 40, which can reduce the difficulty of the electrical connection of the electrical module 10 with the external device and improve the use convenience.

[0059] According to some embodiments of the present application, the electrical module 10 has a positive female connector 11 and a negative female connector 12, a positive male connector is adapted to be electrically connected with the positive female connector 11, and a negative male connector is adapted to be electrically connected with the negative female connector 12.

[0060] That is, the electrical module 10 and the electrical connection assembly are electrically connected through the plug-in form of the female connector and the male connector, the female connector is formed on the electrical module 10, and the male connector on the electrical connection assembly is plugged into the female connector along the assembly direction during the assembly of the board body to the electrical module 10, and the electrical connection is achieved.

[0062] Specifically, the clamping plates 601 are arranged on the male connector body 501 or the female connector body 401, the clamping plates 601 are elastically arranged opposite to each other, a clamping space is defined between the two clamping plates 601, the male connector conductor 502 and the female connector conductor 402 can be in contact in the clamping space, and the male connector conductor 502 and the female connector conductor 402 can be clamped by the clamping plates 601, i.e., elastically pushed against each other, so as to be in close contact and electrically connected.

[0063] In this way, the electrical connection stability of the electrical connection assembly and the electrical module 10 can be improved, the probability of poor contact can be reduced, and the safety can be improved.

[0064] Further, the connecting plate 602 is arranged on the male connector body 501, the connecting plate 602 is located at the end of the male connector body 501 facing the female connector body 401, and the end of the female connector body 401 away from the male connector body 501 is provided with a limiting portion 603 matched with the connecting plate 602.

[0065] That is, the end of the connecting plate 602 can be provided with a buckle or a clamping hole, and the limiting portion 603 is formed as a clamping groove or a buckle, so as to be clamped and matched with the connecting plate 602, to achieve stable and reliable connection of the male connector and the female connector, and further improve the connection stability and reliability.

[0066] As shown in FIGS. 4 and 5, the female connector body 401 is provided with a sealing member 604 to be sealingly matched with the male connector body 501.

[0067] Thus, the sealing of the male and female plugs can be achieved by the sealing member 604, the sealing performance is improved, the probability of open circuit or short circuit is reduced, and the safety and reliability of the energy storage system 100 are improved.

[0068] It should be noted that at least part of the connecting portion 40 is connected with the positive male plug or the negative male plug, and the positive male plug or the negative male plug is located on the end or the middle region of the connecting portion 40, and at least one end of the connecting portion 40 is configured as a lead-out end 41 for external plug-in electrical connection.

[0069] That is, both ends of a part of the connecting portion 40 are formed as lead-out ends 41 for electrical connection across the electrical module 10, one end of a part of the connecting portion is connected with the negative male plug or the positive male plug, and the other end is formed as a lead-out end 41 for connection with the outside. In the embodiment in which the connecting portion 40 has two lead-out ends 41, one lead-out end 41 is configured as a male lead-out end, and the other lead-out end 41 is configured as a female lead-out end, and the male lead-out end of the connecting portion 40 can be plugged into the female lead-out end of the other connecting portion 40.

[0070] As shown in FIGS. 6 and 7, further, the male lead-out end includes a contact portion 411 and a first cover 412 surrounding the contact portion 411, and the first cover 412 is provided with a through hole through which the female lead-out end is arranged to contact the contact portion 411 for electrical connection.

[0071] Specifically, the contact portion 411 is adapted to be electrically connected with the female lead-out end, and the female lead-out end is configured as an exposed end on the connecting portion 40, and the first cover 412 can be configured as a plastic cladding structure and formed as a plastic groove, the groove is formed as a receiving cavity, and the female lead-out end contacts the contact portion 411 for electrical connection, and the plastic groove can elastically clads the female lead-out end and the contact portion 411, improving the stability and reliability of the electrical connection.

[0072] Further, the board is formed as a circuit board, and the connecting portion 40, the positive male plug and the negative male plug are integrated on the circuit board, or the board is formed as a protective cover of the electrical module 10, and the connecting portion 40, the positive male plug and the negative male plug are arranged in the protective cover.

[0073] That is, in some embodiments, the integrated plug-in connector 1 is configured as a circuit board, and the circuit board can be realized for quick disassembly and installation on the electrical module 10, improving the disassembly convenience and reducing the maintenance difficulty, and in other embodiments, the board is formed as a protective cover, and the electrical connection assembly can be integrated in the protective cover, which not only reduces the assembly difficulty, but also realizes the protection of the electrical connection between the electrical connection assembly and the electrical module 10, further improving the safety and reliability.

[0074] As shown in FIG. 1, FIG. 2 and FIG. 3, the energy storage system 100 according to the embodiment of the present application comprises an electric module 10 and an integrated plug 1, the integrated plug 1 is configured as a series plug 20 or a parallel plug 30, and the series plug 20 and the parallel plug 30 are alternatively 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 adapted to be electrically connected with the positive female plug 11 and the negative female plug 12 of the electric module 10.

[0075] Therefore, the electric module 10 can realize series connection or parallel connection with other electric modules 10 by alternatively selecting the series plug 20 or the parallel plug 30.

[0076] Further, the electric module 10 is multiple, and the electric modules 10 are arranged in a first direction, the series plug 20 is selectively arranged in the electric module 10 and is adapted to make the multiple electric modules 10 in series, and the parallel plug 30 is selectively arranged in the electric module 10 and is adapted to make the multiple electric modules 10 in parallel.

[0077] It should be pointed out that the first direction can be any one of the height direction, the length direction or the width direction, which is not limited in the present application.

[0078] It can be understood that the defects of the prior art are mainly that the independent connector is separately arranged to lead out the electrical connection, connected by the wire harness, and then the protective cover is locked after the wiring is tied. The operation at the installation site is complex, and too many connections are prone to errors; if it is a parallel structure, each positive and negative electrode of the battery module needs two connectors, and the external wiring structure cannot be realized when changing from parallel to series, the shell structure needs to be redesigned, and the connector and the wire harness structure need to be rearranged; if the parallel structure is changed to the series structure without changing the structure, the original connector is used for connection, which is prone to errors and leads to system failure, and in severe cases, it may cause thermal runaway risk; at the same time, the prior art uses more power terminal structures in the parallel structure and external wiring mode, which is high in cost and occupies panel space, leading to inconvenient operation or increasing the panel to reduce the energy ratio.

[0079] Based on this, the present application stacks multiple electric modules 10 in a first direction, and when the energy storage system 100 is configured as a series structure, the multiple electric modules 10 can be electrically connected through the series plug 20, and when the energy storage system 100 is configured as a parallel structure, the multiple electric modules 10 can be electrically connected through the parallel plug 30.

[0080] That is, the series plug 20 and the parallel plug 30 are alternatively arranged to configure the energy storage system 100 as a series structure or a parallel structure according to the use requirement, the series plug 20 can be integrated with a series wire harness structure for connecting the multiple electric modules 10 in series, and the parallel plug 30 can be integrated with a parallel wire harness structure for connecting the multiple electric modules 10 in parallel.

[0081] In this way, the series connection or parallel connection of the plurality of electric modules 10 can be achieved without the need for a separately arranged connector, power terminal, etc., without the need for wiring and binding, and the operation at the installation site is simpler, the number of wire harnesses is smaller, the wire harness routing is clearer, the probability of wiring errors can be reduced, and the series structure energy storage system 100 and the parallel structure energy storage system 100 can respectively use series plug-in components 20 and parallel plug-in components 30, without the need for changing the wire harness between series connection and parallel connection, and the probability of wiring errors can be reduced, the risk of thermal runaway can be reduced, the number of connectors and power terminals can be reduced to reduce costs and reduce the space occupation of the panel space of the energy storage system 100, improve the operation convenience, and improve the energy density of the energy storage system 100.

[0082] It should be noted that the electric module 10 can be configured as a battery pack, or a battery pack and a control box are integrated, or a control box, or a transformer box. That is, 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, etc. The energy storage system 100 can also have a plurality of electric modules 10, at least one electric module 10 is configured as a battery pack, one electric module 10 is configured as a battery pack and a control box; at least one electric module 10 can be configured as a battery pack, one electric module 10 can be configured as a control box, and one can be configured as a transformer box.

[0083] Exemplarily, the electric module 10 includes: a first electric module 101, a second electric module 102, and a third electric module 103, the second electric module 102 is stacked and arranged on the first electric module 101 along a first direction, and the third electric module 103 is stacked and arranged on the first electric module 101 along the first direction, and the energy storage system 100 is configured as a series structure, and the series plug-in component 20 includes: a first bottom shield 23 arranged on the first electric module 101, a first intermediate shield 22 arranged on the second electric module 102, and a first top shield 21 arranged on the third electric module 103; or the energy storage system 100 is configured as a parallel structure, and the parallel plug-in component 30 includes: a second bottom shield 33 arranged on the first electric module 101, a second intermediate shield 32 arranged on the second electric module 102, and a second top shield 31 arranged on the third electric module 103.
