The following embodiments are used to illustrate the technical solutions of the present invention, but cannot be used to limit the protection scope of the present invention.

[0036] Embodiment 1:

[0037] As shown in the Figures 1 to 13 accompanying drawings:

[0038] The present invention provides a modular energy storage system that is easy to install, including a cabinet 101 and multiple groups of energy storage battery modules 102. An installation groove 103 is provided on one side of the cabinet 101. Multiple installation components are arranged in the installation groove 103. The installation components include an assembly plate 301. An installation frame 104 is arranged in the installation groove 103. A slidable assembly plate 301 is arranged between the inner walls of the installation frame 104. The energy storage battery module 102 is detachably arranged on the top of the assembly plate 301, facilitating the installation and disassembly of the energy storage battery module 102. At the same time, an electric energy transmission component is also arranged inside the installation groove 103. The electric energy transmission component includes an inverter 401 for connecting to the outside for power supply, and a battery charger 402 for charging multiple groups of energy storage battery modules 102. The inverter 401 can convert direct current into alternating current to provide a reliable and stable power supply for external devices and loads. The battery charger 402 is responsible for charging multiple groups of energy storage battery modules 102 to ensure that they can quickly recover their power and extend the battery life. Two groups of moving components are respectively arranged on both sides of the cabinet 101.

[0039] Please refer to such as Figure 2 , Figure 7 and Figure 8As shown, in addition to the inverter 401 and the battery charger 402, the power transmission component further includes a power strip 403 and a power distribution device 405, which further improves the power supply and management functions of the entire system. Specifically, the power strip 403 is provided on the inner wall of the installation groove 103, and multiple groups of connectors 404 are distributed on it. At the same time, a corresponding connection port 105 is also provided at one end of the energy storage battery module 102. When the energy storage battery module 102 is installed on the assembly plate 301, their respective connection ports 105 only need to be simply docked with the connectors 404 on the power strip 403 to achieve fast and reliable power connection, that is, plug and play, improving the convenience of installation and the detachable nature of the modular battery pack, bringing great convenience to users' daily maintenance and adjustment. On the back of the cabinet 101, a power distribution device 405 is provided, which is responsible for the unified management and power distribution of the power supply of the entire system. The inverter 401, the battery charger 402, and the power strip 403 are all electrically connected to the power distribution device 405 to ensure clear power flow and reliable power distribution. This centralized power distribution method not only facilitates the regular wiring of power lines but also improves the safety and stability of the overall system, providing users with more reliable power protection.

[0040] To ensure seamless connection with the external power grid, a charging interface 406 and multiple groups of output interfaces 407 are provided on one side of the power distribution device 405, providing a reliable power channel for the charging and discharging of the system. A switchable cabinet door 408 is also provided on one side of the power distribution device 405, which not only facilitates users to connect the system to the external power grid but also effectively prevents non-professionals from contacting the internal equipment, ensuring the safety during use.

At the same time, the setting of the safety protection cabinet door 408 also maximally avoids safety hazards caused by improper operation or non-professional contact, further enhancing the practicality and safety of the entire energy storage system.

[0041] Please refer to as Figure 4 、 Figure 5 and Figure 6 shown in

[0042] To facilitate the movement of the cabinet 101, two sets of fixed seats 201 are provided on one side of the cabinet 101. Movable wheels 202 are respectively installed at the bottoms of these two sets of fixed seats 201, enabling the entire cabinet 101 to move flexibly. On one side of each of the two sets of fixed seats 201, a first connecting member 203 is provided, and on the corresponding side of the movable wheel 202, a second connecting member 204 is also provided. The first connecting member 203 and the second connecting member 204 are rotatably connected together by a pin. This not only ensures that the movable wheel 202 can rotate smoothly with the fixed seat 201 but also increases the flexibility of the entire moving assembly, facilitating the user to adjust and optimize the placement of the cabinet 101 according to actual needs.

[0043] Please refer to as Figure 5 and Figure 6 As shown, on the other side of the fixed seat 201, a rotating seat 205 is further provided. The rotating seat 205 is connected by a pin to a rotatable locking buckle 206, and one end of the locking buckle 206 contacts the movable wheel 202, further improving the stability of the movable wheel 202. In addition, two sets of electric push rods 207 are provided on one side of the cabinet 101, and they are all located inside the protective cover 208. The top of the protective cover 208 is also connected by a hinge to a switchable top cover 209, which not only ensures the safe operation of the electric push rods 207 but also facilitates maintenance and repair. On the tops of the two sets of fixed seats 201, multiple fixing holes 210 for passing screws or ground nails are provided, which further enhances the overall stability and firmness of the cabinet 101.

[0044] During installation, the operator only needs to start the four sets of electric push rods 207 to easily lift the entire energy storage system. Then, unlock the locking of the movable wheels 202 by the multiple locking buckles 206 in sequence. Next, through the rotational connection between the first connecting member 203 and the second connecting member 204 on one side, fold up the multiple movable wheels 202. After completing these steps, slowly lower the entire energy storage system so that the multiple fixed seats 201 contact the ground. Subsequently, replace the bolts in the fixing holes 210 with ground nails to quickly complete the installation and fixation. On the contrary, when mobile debugging is required, just operate in the reverse order of the above steps, and the entire energy storage system can be easily moved using the multiple movable wheels 202. This flexible way of moving and fixing not only greatly reduces the manpower and time required for installation but also solves the cumbersome problems in the installation process of traditional energy storage systems and can quickly adapt to different installation scenarios. Whether it is fixed installation or mobile debugging, it can be efficiently completed through the moving assembly, greatly improving the work efficiency and shortening the deployment cycle of this energy storage system.

[0045] Please refer to as Figure 9 and Figure 10 and Figure 11As shown, the installation component further includes two groups of first sliding wheels 302. Two groups of mounting brackets 303 are respectively and fixedly arranged on two opposite inner sides of the mounting frame 104. Two groups of first sliding wheels 302 are respectively rotatably arranged on one side of these two groups of mounting brackets 303. The bottom of the assembly plate 301 is correspondingly provided with two groups of first positioning chutes 304. The two groups of first sliding wheels 302 are respectively located in these two groups of first positioning chutes 304. The sliding actions during the installation process are restricted and defined, enabling the entire energy storage system to slide smoothly along a preset track during installation, greatly improving the convenience and stability of installation.

[0046] Please refer to as Figure 10 And Figure 11 As shown, two groups of connecting seats 305 are respectively arranged on both sides of the assembly plate 301. Two groups of rotatable second sliding wheels 306 are respectively arranged on the sides of these two groups of connecting seats 305 away from the assembly plate 301. At the same time, second positioning chutes 307 are correspondingly opened on two opposite inner sides of the mounting frame 104. The two groups of second sliding wheels 306 are respectively located in these two groups of second positioning chutes 307. One end of the second positioning chute 307 is also provided with a groove that can catch the second sliding wheel 306. This further enhances the stability when replacing the energy storage battery module 102, and also limits the position of the second sliding wheel 306 through the groove at the end of the second positioning chute 307, ensuring that the energy storage system will not be displaced or tilted after installation, thereby further improving the overall safety.

[0047] During the process of replacing the energy storage battery module 102, a magnetic assembly method is adopted. Specifically, a plurality of second magnets 310 are provided at the bottom of the energy storage battery module 102, and a corresponding plurality of first magnets 309 are provided at the top of the assembly plate 301. Pull out the assembly plate 301 and install the plurality of second magnets 310 at the bottom of the energy storage battery module 102 corresponding to the plurality of first magnets 309 at the top of the assembly plate 301 to achieve the rapid installation of the energy storage battery module 102. This magnetic assembly method simplifies the operation process of battery replacement, making maintenance and upgrade extremely convenient. In addition, when the assembly plate 301 is pushed back to its original position, the second sliding wheels 306 on the two groups of connecting seats 305 will respectively be stuck in the groove at the end of the two groups of second positioning chutes 307, further strengthening the stability of the entire system. It not only solves the problem that the battery module of the traditional energy storage system is difficult to maintain and replace, but also greatly reduces the installation difficulty, reduces the cost caused by inconvenient maintenance, and shortens the system downtime caused by battery maintenance. It provides a strong guarantee for the later maintenance and upgrade of the energy storage system, and further improves its practicality and reliability in actual application.

[0048] Please refer to as Figure 10As shown in the figure, at the bottom of the assembly plate 301, there are multiple groups of mounting holes 308, and a first magnet 309 is installed in each mounting hole 308. Correspondingly, at the bottom of the energy storage battery module 102, there are also multiple groups of second magnets 310, and these second magnets 310 exactly correspond to the first magnets 309. When installing the energy storage battery module 102, just align the multiple groups of second magnets 310 at the bottom of it with the multiple groups of mounting holes 308 on the assembly plate 301. With the attraction of magnetic force, the energy storage battery module 102 can be quickly installed. This magnetic force assembly method not only greatly simplifies the installation process and improves the operation convenience, but also ensures the stable connection between the energy storage battery module 102 and the assembly plate 301. It should be noted that at the bottom of each mounting hole 308, there is also an installation seat 311, and these installation seats 311 are detachably connected to the assembly plate 301 by screws, so that the relevant components can be easily replaced or repaired when needed.
