The integrated pluggable component 1 and the energy storage system 100 according to embodiments of this application are described below with reference to Figures 1-13.

As shown in Figure 1, according to an embodiment of this application, the integrated pluggable component 1 is pluggably disposed on the electrical module 10, including a board body and an electrical connection component. The electrical connection component is disposed on the board body and includes: a positive male plug, a negative male plug, and a connecting part 40. The positive male plug and the negative male plug are respectively adapted to be electrically connected to the positive and negative terminals of the electrical module 10, and the connecting part 40 is used for electrical connection with external devices.

Understandably, existing electrical modules 10 primarily rely on separate connectors for electrical connections, wire harnesses, and cable ties before securing the protective cover. This results in complex on-site installation, with numerous wiring connections increasing the risk of errors. In parallel configurations, each battery module requires two connectors for both positive and negative power outputs. Converting from parallel to series connection makes external wiring impossible, necessitating a redesign of the housing and a rearrangement of the connectors and wiring harnesses. Furthermore, using existing connectors for series connection without structural changes can easily lead to system failures and, in severe cases, thermal runaway. Additionally, existing parallel configurations with external wiring often utilize multiple power terminal structures, increasing costs and occupying panel space, leading to inconvenient operation or reduced energy density when the panel size is increased.

Based on this, this application proposes an integrated plug-in component 1, which integrates an electrical connection component into a board body. The board body can be formed as a decorative panel on one end or one side of the electrical module 10. While assembling the integrated plug-in component 1 on the electrical module 10, the electrical connection between the electrical connection component and the electrical module 10 can be realized. The electrical connection between the electrical module 10 and the outside can be realized through the connection part 40 of the electrical connection component.

It should be noted that the electrical connection between the electrical module 10 and the outside can be that the connection part 40 is used as the output terminal to transmit the electrical energy of the electrical module 10 to the outside, that is, the load is connected through the electrical connection part 40, or the connection part 40 can be connected in series or in parallel with other electrical modules 10 around it.

According to the embodiment of this application, the integrated plug-in component 1 integrates an electrical connection component within the board. While assembling the integrated plug-in component 1 on the electrical module 10, the electrical module 10 can be electrically connected to the electrical connection component, reducing wiring difficulty, thereby reducing the probability of errors and improving safety and reliability. Furthermore, the electrical module 10 can be electrically connected to the outside through the connection part 40, which can reduce the difficulty of electrical connection between the electrical module 10 and the outside and improve ease of use.

According to some embodiments of this application, the electrical module 10 has a positive female plug 11 and a negative female plug 12, the positive male plug is adapted to be electrically connected to the positive female plug 11, and the negative male plug is adapted to be electrically connected to the negative female plug 12.

In other words, the electrical module 10 and the electrical connection component are electrically connected through the plug-in form of female and male plugs. The female plug is formed on the electrical module 10, and the male plug on the electrical connection component is plugged into the female plug along the assembly direction during the process of assembling the board to the electrical module 10 to achieve electrical connection. This can improve the stability and reliability of the electrical connection, reduce the difficulty of converting the electrical connection between the electrical connection component and the electrical module 10, and improve the convenience of assembly.

As shown in Figures 4 and 5, both the positive and negative male plugs include a male plug body 501 and a male plug conductor 502. Both the positive female plug 11 and the negative female plug 12 include a female plug body 401 and a female plug conductor 402. The male plug body 501 and the female plug body 401 are plugged into each other, and the male plug conductor 502 is electrically connected to the female plug conductor 402.

Specifically, a clamping plate 601 is provided on the male connector body 501 or the female connector body 401. The clamping plate 601 is elastic and 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 contact and cooperate within the clamping space. The clamping plate 601 can clamp the male connector conductor 502 and the female connector conductor 402, that is, elastically push the two together so that they fit together and are electrically connected.

This improves the stability of the electrical connection between the electrical connection components and the electrical module 10, reduces the probability of poor contact, and enhances safety.

Furthermore, a connecting plate 602 is provided on the male plug body 501. The connecting plate 602 is located at the end of the male plug body 501 facing the female plug body 401. A limiting part 603 that cooperates with the connecting plate 602 is provided at the end of the female plug body 401 away from the male plug body 501.

In other words, the end of the connecting plate 602 may be provided with a buckle or a buckle hole, and the corresponding limiting part 603 is formed as a buckle or a slot, so that the male and female plugs can be stably and reliably connected by the buckling cooperation between the connecting plate 602 and the limiting part 603, thereby further improving the connection stability and reliability.

As shown in Figures 4 and 5, a sealing element 604 is provided on the female plug body 401 to seal and cooperate with the male plug body 501.

Therefore, the sealing element 604 can be used to achieve a sealed fit between the male and female plugs, improve the sealing performance, reduce the probability of open circuit or short circuit, and improve the safety and reliability of the energy storage system 100.

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

In other words, both ends of a portion of the connection part 40 are formed as leads 41 to facilitate electrical connection with the cross-current module 10. One end of a portion of the connection part is connected to the negative or positive male plug, and the other end is formed as a lead 41 to facilitate connection of the lead 41 to the outside. In an embodiment where the connection part 40 has two leads 41, one lead 41 is constructed as a male lead and the other lead 41 is constructed as a female lead, and the male lead of the connection part 40 can be plugged into and engaged with the female lead of the other connection part 40.

As shown in Figures 6 and 7, the male lead further includes a contact portion 411 and a first cover 412 surrounding the contact portion 411. The first cover 412 is provided with a through hole, and the female lead passes through the through hole and contacts the contact portion 411 for electrical connection.

Specifically, the contact portion 411 is adapted to be electrically connected to the lead-out female end, which is constructed as an exposed end on the connection portion 40. The first cover 412 can be constructed as a plastic covering structure and formed as a plastic groove, which is formed as a receiving 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.

Furthermore, the board body is formed as a circuit board, and the connecting part 40, the positive terminal plug and the negative terminal plug are all integrated into the circuit board, or the board body is formed as a protective cover for the electrical module 10, and the connecting part 40, the positive terminal plug and the negative terminal plug are all disposed in the protective cover.

In other words, 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, 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 components can be integrated inside the protective cover, which not only reduces the assembly difficulty, but also protects the electrical connection between the electrical connection components and the electrical module 10, further improving safety and reliability.

As shown in Figures 1, 2 and 3, the energy storage system 100 according to an embodiment of this application includes: an electrical module 10 and an integrated plug-in component 1. The integrated plug-in component 1 is configured as a series plug-in component 20 or a parallel plug-in component 30, and one of the series plug-in component 20 and the parallel plug-in component 30 is selected and disposed at the end of the electrical module 10. The positive male plug and the negative male plug of the integrated plug-in component 1 are respectively adapted to be electrically connected to the positive female plug 11 and the negative female plug 12 of the electrical module 10.

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

Furthermore, there are multiple electrical modules 10, and the electrical modules 10 are stacked along the first direction. The series plug-in member 20 can be selectively disposed on the electrical module 10 and is adapted to connect multiple electrical modules 10 in series. The parallel plug-in member 30 can be selectively disposed on the electrical module 10 and is adapted to connect multiple electrical modules 10 in parallel.

It should be noted that the first direction can be any one of the height direction, length direction or width direction, and this application does not make any specific limitation.

Understandably, the main drawbacks of existing technologies lie in the complexity of installation. This involves using separate connectors for electrical connections, wiring harnesses, and securing the protective cover after wiring and bundling. Too many connections increase the risk of errors. In parallel configurations, each battery module requires two connectors for both positive and negative power outputs. Converting from parallel to series connection makes external wiring impossible, necessitating a redesign of the housing and a rearrangement of the connectors and wiring harnesses. Furthermore, using existing connectors for parallel-to-series conversion without structural changes can easily lead to system failure and, in severe cases, thermal runaway. Additionally, existing technologies using external wiring in parallel configurations often employ multiple power terminal structures, increasing costs and occupying panel space, leading to inconvenient operation or reduced energy density when the panel size is increased.

Based on this, this application stacks multiple electrical modules 10 in the first direction. When the energy storage system 100 is configured in a series structure, the multiple electrical modules 10 can be electrically connected through the series plug-in 20. When the energy storage system 100 is configured in a parallel structure, the multiple electrical modules 10 can be electrically connected through the parallel plug-in 30.

In other words, the series plug-in component 20 and the parallel plug-in component 30 are selected to construct the energy storage system 100 as a series structure or a parallel structure according to the usage requirements. The series plug-in component 20 may integrate a series wiring harness structure for connecting multiple electrical modules 10 in series, and the parallel plug-in component 30 may integrate a parallel wiring harness structure for connecting multiple electrical modules 10 in parallel.

In this way, multiple electrical modules 10 can be connected in series or in parallel without the need for separately designed connectors, power terminals, etc., eliminating the need for wiring and tying. This simplifies on-site operation, reduces the number of wiring harnesses, and makes wiring routing clearer, thus reducing the probability of wiring errors. Furthermore, the series structure energy storage system 100 and the parallel structure energy storage system 100 can respectively use a combination of series plug-in components 20 and parallel plug-in components 30, eliminating the need for wiring harness changes between parallel and series connections. This further reduces the probability of wiring errors, lowers the risk of thermal runaway, and reduces the number of connectors and power terminals, thereby reducing costs and minimizing the space occupied on the panel of the energy storage system 100. This improves operational convenience and increases the energy density of the energy storage system 100.

It should be noted that the electrical module 10 can be constructed as a battery pack, or a battery pack integrated with a control box, or a control box, or a substation. That is to say, the energy storage system 100 can have one electrical module 10, which integrates a battery pack, a control box, or a structure integrating a battery pack and a substation. The energy storage system 100 can also have multiple electrical modules 10, where at least one electrical module 10 is constructed as a battery pack, and one electrical module 10 is constructed as an integration of a battery pack and a control box; alternatively, at least one electrical module 10 can be constructed as a battery pack, one electrical module 10 can be constructed as a control box, and one can be constructed as a substation.

For example, 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 top of the first electrical module 101 along a first direction, and the third electrical module 103 is stacked on top of the first electrical module 101 along the first direction. The energy storage system 100 is configured in a series structure, and the series plug-in component 20 includes a first bottom cover 23 disposed on the first electrical module 101, a first intermediate cover 22 disposed on the second electrical module 102, and a first top cover 21 disposed on the third electrical module 103. Alternatively, the energy storage system 100 is configured in a parallel structure, and the parallel plug-in component 30 includes a second bottom cover 33 disposed on the first electrical module 101, a second intermediate cover 32 disposed on the second electrical module 102, and a second top cover 31 disposed on the third electrical module 103.

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. At the same time, the first bottom cover 23, the first middle cover 22 and the first top cover 21 realize the series electrical connection of the three electrical modules 10; or the second bottom cover 33, the second middle cover 32 and the second top cover 31 realize the parallel electrical connection of the three electrical modules 10.

It should be noted that when the parallel structure needs to be switched to the series structure, the change can be achieved quickly simply by changing the series plug-in 20 to the parallel plug-in 30. Of course, the internal functions of the multiple electrical modules 10 need to be compatible with the series-parallel switching or updated, without redesigning the housing, protective cover and external wiring of the electrical module 10. The lead-out terminals 41 on the electrical module 10 can be arranged according to the design requirements. After the design is finalized, it can be used in a standardized manner. The wiring is simple, and there is no need for wiring and tying. 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.

It is understandable that adjacent electrical modules 10 can be quickly disconnected through plug-in structures, snap-fit structures, or interlocking plates, which further reduces assembly difficulty and improves the assembly efficiency and ease of use of the energy storage system 100.

According to the embodiment of this application, the energy storage system 100 is equipped with a series plug-in component 20 and a parallel plug-in component 30, and the series plug-in component 20 and the parallel plug-in component 30 can be selected for one of them. The parallel structure and the series structure can be quickly changed without redesigning the protective cover and external wiring harness. It can be used in a standardized manner without setting up separate wiring and wiring ties, which can improve assembly efficiency, effectively prevent errors, and improve the working stability and safety of the energy storage system 100.

As shown in Figure 3, according to some embodiments of this application, the electrical module 10 has a positive female plug 11 and a negative female plug 12, and the series plug-in component 20 and the parallel plug-in component 30 both have a positive male plug and a negative male plug. The positive male plug is suitable for electrical connection with the positive female plug 11, and the negative male plug is suitable for electrical connection with the negative female plug 12.

In other words, both the series plug-in component 20 and the parallel plug-in component 30 integrate a positive male plug and a negative male plug. The positive male plug is electrically connected to the positive female plug 11, and the negative male plug is electrically connected to the negative female plug 12, so that each electrical module 10 can be connected in series with other electrical modules 10 in the energy storage system 100 through the corresponding series plug-in component 20, or can be connected in parallel with other electrical modules 10 in the energy storage system 100 through the parallel plug-in component 30.

For example, the first electrical module 101 has a bottom positive female plug and a bottom negative female plug, the second electrical module 102 has a middle positive female plug and a middle negative female plug, and the third electrical module 103 has a top positive female plug and a top negative female plug. The series plug-in 20 is adapted to connect the bottom positive female plug, the bottom negative female plug, the middle positive female plug, the middle negative female plug, the top positive female plug, and the top negative female plug in sequence through the negative male plug and the positive male plug therein. The parallel plug-in 30 is adapted to connect the bottom positive female plug, the middle positive female plug, and the top positive female plug through the positive male plug and the negative male plug therein, and to connect the bottom negative female plug, the middle negative female plug, and the top negative female plug in sequence.

Therefore, by directly leading out the positive female plug 11 and the negative female plug 12 from the electrical module 10, and setting the corresponding positive male plug and negative male plug inside the protective cover, series connection or parallel connection can be achieved. This makes installation more convenient, reduces the number of wires, makes wiring easier, reduces the probability of errors, and improves the working stability and reliability of the energy storage system 100.

As shown in Figures 8, 9, and 10, the series plug-in component 20 further includes a first positive male plug 201 and a first negative male plug 202. The first positive male plug 201 is electrically connected to the positive female plug 11, and the first negative male plug 202 is electrically connected to the negative female plug 12. Furthermore, between adjacent electrical modules 10 or between inter-electrical modules 10, the first positive male plug 201 of one series plug-in component 20 is electrically connected to the first negative male plug 202 of another series plug-in component 20 through a connecting part 40, and the first positive male plug 201 of one series plug-in component 20 is electrically connected to the first negative male plug 202 of another series plug-in component 20 through a connecting part 40.

In other words, among the multiple series plug-in components 20, the first positive male plug 201 of the top series plug-in component 20 is electrically connected to the first negative male plug 202 of the bottom series plug-in component 20, and the first positive male plug 201 of one of the adjacent series plug-in components 20 is electrically connected to the first negative male plug 202 of the other, so as to achieve series electrical connection.

For example, the series plug-in component 20 includes: a first bottom cover 23, a first intermediate cover 22, and a first top cover 21. The first positive male connector 201 of the first bottom cover 23 is connected to the positive female connector 11 of the first electrical module 101, and the first negative male connector 202 is connected to the negative female connector 12 of the first electrical module 101. The first positive male connector 201 of the first intermediate cover 22 is connected to the positive female connector 11 of the second electrical module 102, and the first negative male connector 202 is connected to the negative female connector 12 of the second electrical module 102. The first positive male connector 201 of the first top cover 21 is connected to the third electrical module 102. The positive female connector 11 of the first electrical module 103 is connected to the negative female connector 12 of the third electrical module 103, the first positive male connector 201 of the first top layer shield 21 is electrically connected to the first negative male connector 202 of the first bottom layer shield 23, the first positive male connector 201 of the first bottom layer shield 23 is electrically connected to the first negative male connector 202 of the first middle shield 22, and the first positive male connector 201 of the first middle shield 22 is electrically connected to the first negative male connector 202 of the first top layer shield 21, so as to realize the series electrical connection of the first electrical module 101, the second electrical module 102 and the third electrical module 103.

In this way, the electrical connection between multiple electrical modules 10 is achieved by integrating the first positive male plug 201 and the first negative male plug 202 within the series plug-in component 20, which makes the electrical connection easier and the assembly efficiency higher.

As shown in Figures 11, 12, and 13, in some embodiments, the parallel plug-in 30 has a second positive male plug 301 and a second negative male plug 302. The second positive male plug 301 is electrically connected to the positive female plug 11, and the second negative male plug 302 is electrically connected to the negative female plug 12. Between adjacent electrical modules 10 or between electrical modules 10, the second positive male plug 301 of one parallel plug-in 30 is electrically connected to the second positive male plug 301 of another parallel plug-in 30, and the second negative male plug 302 of one parallel plug-in 30 is electrically connected to the second negative male plug 302 of another parallel plug-in 30.

In other words, among multiple parallel plug-in components 30, the second positive male plug 301 of one of the adjacent series plug-in components 20 is electrically connected to the second positive male plug 301 of the other, and the second negative male plug 302 of one is electrically connected to the second negative male plug 302 of the other, so that the parallel electrical connection of multiple electrical modules 10 can be realized.

For example, the parallel plug-in component 30 includes a second bottom cover 33, a second intermediate cover 32, and a second top cover 31. The positive female plug 11 of the first electrical module 101 is electrically connected to the second positive male plug 301 of the second bottom cover 33, and the negative female plug 12 is electrically connected to the second negative male plug 302 of the second bottom cover 33. The positive female plug 11 of the second electrical module 102 is electrically connected to the second positive male plug 301 of the second intermediate cover 32, and the negative female plug 12 is electrically connected to the second negative male plug 302 of the second intermediate cover 32. The positive female plug 11 of the third electrical module 103 is electrically connected to the second positive male plug 301 of the second top cover 31, and the negative female plug 12 is electrically connected to the second negative male plug 302 of the second intermediate cover 32. The second negative male connector 302 of the second top layer shield 31 is electrically connected, while the second positive male connector 301 of the second top layer shield 31 is electrically connected to the second positive male connector 301 of the second middle shield 32, the second positive male connector 301 of the second middle shield 32 is electrically connected to the second positive male connector 301 of the second bottom layer shield 33, the second negative male connector 302 of the second top layer shield 31 is electrically connected to the second negative male connector 302 of the second middle shield 32, and the second negative male connector 302 of the second middle shield 32 is electrically connected to the second negative male connector 302 of the second bottom layer shield 33, so as to realize the parallel electrical connection of the first electrical module 101, the second electrical module 102 and the third electrical module 103.

In this way, the electrical connection between multiple electrical modules 10 is achieved by integrating the second positive male plug 301 and the second negative male plug 302 within the parallel plug-in component 30, which makes the electrical connection easier and the assembly efficiency higher.

Referring to Figures 6 to 13, in some embodiments, different module electrical modules 10 are electrically connected to each other through a connecting part 40. The two ends of the connecting part 40 are respectively provided with a male lead and a female lead, or one end is connected to a positive male plug or a negative male plug, and the other end is provided with a female lead. Between two connected connecting parts 40, the male lead of one connecting part 40 is plugged into and engaged with the female lead of the other connecting part 40.

In other words, both the series plug-in component 20 and the parallel plug-in component 30 integrate a connecting part 40. The two ends of the connecting part 40 are respectively formed as a male lead and a female lead, or one end is connected to the positive male plug and the other end is provided with a female lead, or one end is connected to the negative male plug and the other end is provided with a female lead. Through the connecting part 40 provided in the series plug-in component 20 and the parallel plug-in component 30, multiple electrical modules 10 can be connected in series or in parallel. The wiring harness is fixed, the connection concept is clear, the probability of wiring errors is lower, and the stability and reliability of the energy storage system 100 are higher.

For example, as shown in Figures 8, 9, and 10, the first top-layer shield 21 has two connecting parts 40, defined as a first wire harness and a second wire harness, respectively. One end of the first wire harness is connected to the positive male connector, and the other end extends downward to form a first end. One end of the second wire harness is connected to the negative male connector, and the other end extends downward to form a second end. The first intermediate shield 22 has three connecting parts 40, defined as a third wire harness, a fourth wire harness, and a fifth wire harness, respectively. One end of the third wire harness is connected to the positive male connector, and the other end extends upward to form a... One end of the fourth wire harness is connected to the negative male plug, and the other end extends downward to form a fourth end. The two ends of the fifth wire harness are respectively formed as the fifth end and the sixth end. Three connecting parts 40 are provided inside the first bottom layer shield 23, which are respectively defined as the sixth wire harness, the seventh wire harness and the eighth wire harness. One end of the sixth wire harness is connected to the positive male plug, and the other end extends upward to form a seventh end. One end of the seventh wire harness is connected to the negative male plug, and the other end extends downward to form an eighth end. The two ends of the eighth wire harness are respectively formed as the ninth end and the tenth end.

Here, the extension toward the first top layer shield 21 is defined as upward, and the extension toward the first bottom layer shield 23 is defined as downward.

Furthermore, the first end is connected to the fifth end, the sixth end is connected to the ninth end, the tenth end is connected to the eighth end, the seventh end is connected to the fourth end, and the third end is connected to the second end, so that the first electrical module 101, the second electrical module 102, and the third electrical module 103 are connected in series.

As shown in Figure 10, further, when multiple electrical modules 10 are connected in series, the lead-out female end of the connection part 40 in the series plug-in member 20 located at one end of the first direction, which is electrically connected to the positive male plug, and the lead-out female end of the connection part 40 of the negative male plug are electrically connected through the series protective sleeve 80.

In other words, in the series-connected energy storage system 100, one end in the first direction serves as the output end, while the tenth and eighth ends in the other end are electrically connected through a series plug-in 20. The series plug-in 20 can provide insulation and sealing protection (e.g., waterproofing) to improve the reliability and stability of the energy storage system 100.

For example, when the first electrical module 101, the second electrical module 102 and the third electrical module 103 are connected in series, and the first electrical module 101 is the bottom module, a series plug-in component 20 is provided in the first bottom protective cover 23 corresponding to the first electrical module 101 to achieve insulation and waterproof protection.

As shown in Figures 11, 12, and 13, the second top-layer protective cover 31 has two connecting parts 40, defined as the first wire harness and the second wire harness, respectively. One end of the first wire harness is connected to the positive male connector, and the other end forms a first end. One end of the second wire harness is connected to the negative male connector, and the other end forms a second end. The second intermediate protective cover 32 has four connecting parts 40, defined as the third wire harness, the fourth wire harness, the fifth wire harness, and the sixth wire harness, respectively. One end of the third wire harness is connected to the positive male connector, and the other end extends upward to form a third end. One end of the fourth wire harness is connected to the negative busbar, and the other end extends upward to form a fourth end. One end of the fifth wire harness is connected to the positive... The busbars are connected, and the other end extends downward to form the fifth end. One end of the sixth wire harness is connected to the positive busbar, and the other end extends downward to form the sixth end. Four connecting parts 40 can be provided inside the second bottom layer cover 33, which are respectively defined as the seventh wire harness, the eighth wire harness, the ninth wire harness and the tenth wire harness. One end of the seventh wire harness is connected to the positive male plug, and the other end extends upward to form the seventh end. One end of the eighth wire harness is connected to the negative busbar, and the other end extends upward to form the eighth end. One end of the ninth wire harness is connected to the positive busbar, and the other end extends downward to form the ninth end. One end of the tenth wire harness is connected to the positive busbar, and the other end extends downward to form the tenth end.

The term "extending towards the second top layer shield 31" is defined as "upward", and "extending towards the second bottom layer shield 33" is defined as "downward".

Then, the first terminal is connected to the third terminal, the fifth terminal is connected to the seventh terminal, the ninth terminal is disconnected, the second terminal is connected to the fourth terminal, the sixth terminal is connected to the eighth terminal, and the tenth terminal is disconnected, so that the first electrical module 101, the second electrical module 102 and the third electrical module 103 are connected in parallel.

It should be noted that a ninth and tenth wiring harness can be installed inside the second bottom cover 33. In this case, the second bottom cover 33 has the same structure as the second intermediate cover 32, which can realize the universal setting of at least some of the parallel plug-in components 30. Furthermore, for the sake of subsequent expansion of the parallel energy storage system 100, the ninth and tenth wiring harnesses can also be omitted from the second bottom cover 33, which can reduce the amount of wiring harness used and reduce costs, but is not conducive to the later expansion of the energy storage system 100.

As shown in Figure 13, when the electrical modules 10 are connected in parallel, a parallel protective sleeve 90 is provided on the lead-out female end of the connection part 40, which is far away from the second positive male plug 301 and the second negative male plug 302 in the parallel plug-in component 30 located at one end of the first direction.

In other words, in the parallel structure of the energy storage system 100, one end in the first direction serves as the output end, while the tenth and ninth ends in the other end are respectively protected by insulation and sealing (e.g., waterproofing) through parallel plug-in components 30, so as to improve the reliability and stability of the energy storage system 100.

For example, when the first electrical module 101, the second electrical module 102 and the third electrical module 103 are connected in series, and the first electrical module 101 is the bottom module, a parallel plug-in component 30 is provided in the second bottom protective cover 33 corresponding to the first electrical module 101 to achieve insulation and waterproof protection.

It should be noted that both the parallel plug-in component 30 and the series plug-in component 20 are constructed of insulating rubber material, while the series plug-in component 20 may have a metal component embedded inside, so as to realize the electrical connection of the two connecting parts 40 electrically connected by the series plug-in component 20 in the series structure. The connecting part 40 can be a conductive structure and is coated with an insulating layer to realize the insulation between modules, while the end is exposed to facilitate electrical connection.

Referring to Figures 8 to 13, in some embodiments, the electrical module 10 has a wire harness female plug 13, and the series plug-in component 20 and the parallel plug-in component 30 are provided with signal wire harnesses 50, and the signal wire harnesses 50 are connected to the signal female plug.

It should be noted that the signal harness 50 does not need to be set on the end of the energy storage system 100 in the first direction, but both ends of the signal harness 50 are provided with harness male plugs. Each electrical module 10 can have one or more harness female plugs 13. Multiple electrical modules 10 can be connected by signal harness 50. However, an electrical module 10 that integrates a controller or is formed as a controller only needs to be provided with one harness female plug 13. An electrical module 10 located at the end can also only be provided with one harness female plug 13.

For example, the first electrical module 101 is provided with a female wire harness connector 13, the second electrical module 102 is provided with two female wire harness connectors 13, and the third electrical module 103 is provided with a female wire harness connector 13. One end of the signal wire harness 50 in the first bottom cover 23 or the second bottom cover 33 is inserted into the female wire harness connector 13 of the first electrical module 101, and the other end is inserted into one female wire harness connector 13 of the second electrical module 102. One end of the signal wire harness 50 in the first intermediate cover 22 or the second intermediate cover 32 is inserted into another female wire harness connector 13 of the second electrical module 102, and the other end is inserted into the female wire harness connector 13 of the third electrical module 103, so that the electrical signals of the first electrical module 101, the second electrical module 102 and the third electrical module 103 are all collected into the controller integrated in the third electrical module 103, which facilitates the unified control of the energy storage system 100.

As shown in Figures 1 and 2, in some embodiments, the energy storage system 100 further includes: a decorative protective cover 60, a series plug-in component 20 or a parallel plug-in component 30 disposed on one side of the module electrical module 10, and the decorative protective cover 60 disposed on the other side of the electrical module 10.

Therefore, by setting up the decorative protective cover 60, the series plug-in component 20 and the parallel plug-in component 30, the aesthetics of the energy storage system 100 can be improved and the structural strength of the energy storage system 100 can be increased.

It should be noted that the dimensions of multiple electrical modules 10 may be the same or different, and the dimensions of multiple decorative protective covers 60, multiple series plug-in components 20 and multiple parallel plug-in components 30 may be the same or different. For example, if the first electrical module 101 and the second electrical module 102 have the same structure, then the dimensions of the first bottom cover 23 and the first middle cover 22 are the same, and the dimensions of the second bottom cover 33 and the second middle cover 32 are the same. However, the dimensions of the first top cover 21 and the first bottom cover 23 corresponding to the third electrical module 103 are different, and the dimensions of the second top cover 31 and the second bottom cover 33 are different.

Furthermore, the decorative protective cover 60, the series plug-in component 20, and the parallel plug-in component 30 are all constructed as quick-release structures and fixed to the corresponding electrical module 10.

Specifically, quick-release structures can be snap-fit structures, plug-in structures, or magnetic structures, etc.

Therefore, the electrical module 10, after being stacked and wired, does not need to be fastened with bolts or other fasteners. Instead, it can be connected by a magnetic attraction and a male and female plug-in structure, which can reduce the time spent operating other locking structures and make the appearance neater.

It should be noted that the connecting part 40 can be an aluminum busbar, a conductor, or a wire harness, as long as it meets the electrical and thermal design requirements, and this application does not impose any further limitations.

As shown in Figure 1, according to some embodiments of this application, the energy storage system 100 further includes a base 70, which is disposed at one end of the energy storage system 100 in a first direction and fixed to the electrical module 10.

Therefore, by setting the base 70, the energy storage system 100 can obtain a larger ground clearance, thereby reducing the probability of water ingress into the electrical module 10 located below and improving the stability and reliability of the energy storage system 100.

Other configurations and operations of the energy storage system 100 according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
