[0040] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0041] First Embodiment
[0042] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in, Figure 1 A schematic diagram of the structure of the first embodiment of the charging device based on distributed mobile energy storage provided by this utility model; Figure 2 This invention provides a structural schematic diagram of the first energy storage battery pack. Figure 3Provided for this utility model Figure 2 An enlarged view of point A shown; Figure 4 This invention provides a schematic diagram of distributed energy storage charging principle. Figure 5 Provided for this utility model Figure 2 The enlarged view at point B is shown. The charging device based on distributed mobile energy storage includes: a mounting base 1 and an AGV autonomous driving chassis 9;
[0043] The charging pile 10 is installed inside the mounting base 1. Connectors 22 are installed on the top of the charging pile 10 near both sides. An energy buffer controller 2 is installed on the top of the charging pile 10. A charging rod 3 is installed on the top of the mounting base 1 near the front. Multiple hanging brackets 4 are installed on the outer surface of the charging rod 3 near the top. A charging gun 5 is provided on the outer surface of the hanging bracket 4.
[0044] A bracket 8 is mounted on top of an AGV autonomous driving chassis 9. An energy storage battery pack 7 is mounted on the top of the bracket 8, and a reinforcement component 6 is provided on the outer surface of the energy storage battery pack 7.
[0045] The connector 22 is divided into DC and AC types. The two ends of the charging gun 5 are connected to the vehicle charging port and the connector 22 respectively. The docking structure 703 at the bottom of the energy storage battery pack 7 is connected to the connector 22 to enable power supply. The reinforcement component 6 can increase the stability of the connection between the energy storage battery pack 7 and the bracket 8. The bracket 8 is fixedly connected to the AGV autonomous driving chassis 9. The AGV autonomous driving chassis 9 can move automatically along the track and has a built-in lifting structure that can lift the bracket 8 to the corresponding height. The energy storage battery pack 7 has a built-in heat dissipation function.
[0046] Compared to traditional charging stations that rely on fixed grid interfaces and face high expansion costs and load surge risks, and fixed energy storage that, while providing buffering, lacks cross-regional dispatch capabilities, mobile energy storage charging systems construct a distributed energy supply architecture of "dynamic energy storage resource pool + intelligence." This architecture utilizes standardized modular mobile energy storage packages, which are centrally charged during off-peak hours or in areas with surplus grid capacity, forming a distributed energy storage resource pool. Combined with an intelligent dispatch system for unmanned AGV clusters, this system is based on a three-layer decision-making architecture: a central EMS engine, edge AGV controllers, and a terminal sensing network. Furthermore, it integrates a high-dynamic-response energy buffer and an intelligent power distribution system at the charging terminal, solving the power fluctuation and interface compatibility problems inherent in direct power supply from mobile energy storage packages. This significantly improves the actual output power of charging piles without increasing or minimizing the instantaneous load on the grid side. It achieves spatiotemporal energy transfer using distributed mobile energy storage, and through flexible charging and discharging strategies and energy storage resource dispatch, it develops diversified profit models, including peak-valley arbitrage, demand response, reserve capacity, and differentiated services.

The docking structure 703 is used to connect the first energy storage battery group 701 and the second energy storage battery group 702, which are distributed vertically.
[0048] The first energy storage battery pack 701 and the second energy storage battery pack 702 are both independent battery packs. If a single battery pack is damaged, it can be disassembled and replaced or charged individually. The docking structure 703 is the connecting plug of the first energy storage battery pack 701 and the second energy storage battery pack 702, which is used to increase the capacity of the energy storage battery pack 7. The first energy storage battery pack 701 and the second energy storage battery pack 702 have the same composition and can be stacked as needed. The docking structure 703 is provided with convenient assembly at the top and bottom of the energy storage battery pack. The first energy storage battery pack 701 of the same specifications can be stacked on top of the second energy storage battery pack 702.
[0049] Please refer to Figure 1 , Figure 2 and Figure 3 The first energy storage battery pack 701 and the second energy storage battery pack 702 are connected by a fixing component 11. The fixing component 11 includes a docking component 111, a monitoring component 112, and an insertion structure 113. The insertion structure 113 is installed at the bottom of the first energy storage battery pack 701 or the second energy storage battery pack 702, the monitoring component 112 is installed at the top of the insertion structure 113, the docking component 111 is installed at the first energy storage battery pack 701 or the second energy storage battery pack 702, and the insertion structure 113 is inserted from the top of the docking component 111.
[0050] After the insertion structure 113 is inserted into the docking component 111, it needs to be reinforced with bolts. The bottom contact between the monitoring component 112 and the inner wall of the docking component 111 is used to monitor the connection stability. The fixing component 11 provides a certain distance between the first energy storage battery pack 701 and the second energy storage battery pack 702 to facilitate heat dissipation.
[0051] Please refer to Figure 1 and Figure 2 The reinforcement component 6 includes a protective cover 601, a fixing structure 602, and a connecting structure 603. The protective cover 601 is located on the top layer of the energy storage battery pack 7. The fixing structure 602 is used to connect the two ends of the connecting structure 603 to the protective cover 601 and the bracket 8, respectively.
[0052] The frame consisting of the connecting structure 603 and the protective cover 601 is used to increase the stability of multiple first energy storage battery packs 701 and second energy storage battery packs 702.
[0053] Please refer to Figure 1 , Figure 2 and Figure 5 The mounting base 1 includes a base plate 101, an extension plate 102 and a mounting hole 103. The mounting hole 103 is opened on the top of the base plate 101, and the extension plate 102 is located on the front of the base plate 101 for mounting the charging rod 3.
[0054] The mounting holes 103 are located at the top of the base plate 101 near the four corners. The mounting holes 103 facilitate the passage of bolts to fix the base plate 101 in the corresponding positions.
[0055] The working principle of the charging device based on distributed mobile energy storage provided by this utility model is as follows:
[0056] In actual use, the energy storage battery pack 7 is first installed on top of the bracket 8 and reinforced by the reinforcing component 6. Then, the AGV autonomous driving chassis 9 at the bottom of the bracket 8 can drive the energy storage battery pack 7 to move along a preset trajectory. The energy buffer controller 9 with the charging pile 10 is installed in the corresponding position through the mounting base 1, and the two connectors 22 on the charging pile 10 are located in a convenient position to connect with the energy storage battery pack 7. When the energy storage battery pack 7 needs to be dispatched, the user places an order on the energy buffer controller 9. During this process, the AGV autonomous driving chassis 9 moves the fully charged energy storage battery pack 7 to the corresponding position of the energy buffer controller 2, and connects the energy storage battery pack 7 with the connectors 22 through the AGV autonomous driving chassis 9. This allows the charging gun 5 to be connected to the connectors 22 for charging. When the energy storage battery pack 7 has a low power or is at a low peak, the AGV autonomous driving chassis 9 can drive the energy storage battery pack 7 back to the charging position for charging. If the energy storage battery pack 7 needs to be moved during this process, the same method can be used to place an order, and the AGV autonomous driving chassis 9 will carry the energy storage battery pack 7 to provide power support to the position that needs power.
[0057] Compared with related technologies, the charging device based on distributed mobile energy storage provided by this utility model has the following beneficial effects:
[0058] To achieve greater flexibility in the energy storage charging system and reduce costs and initial investment, an AGV autonomous driving chassis 9 and a support frame 8 are used to move the energy storage battery pack 7 according to a preset trajectory. This enables the energy storage battery pack 7 to move flexibly, reducing the initial investment in the charging system. It also allows for charging during off-peak hours and discharging during peak hours, charging in areas with surplus capacity and discharging in areas with high demand, increasing flexibility. Furthermore, the energy buffer controller 2 enables fast charging at rated power, increasing convenience. This design, combined with the intelligent scheduling system of the AGV autonomous driving chassis 9 cluster, enables rapid movement of the energy storage battery pack 7. A dynamic resource matching engine calculates the overall cost of the energy storage battery pack 7, and a multi-AGV autonomous driving chassis 9 collaborative strategy optimizes the path. Simultaneously, the energy buffer controller 2 ensures precise power supply to the fast and slow charging interfaces, improving the flexibility of the energy storage charging system and reducing costs and initial investment.

The second embodiment of this application proposes another charging device based on distributed mobile energy storage. The second embodiment is merely a preferred embodiment of the first embodiment, and its implementation will not affect the independent implementation of the first embodiment.
[0061] Specifically, the difference in the charging device based on distributed mobile energy storage provided in the second embodiment of this application is that, please refer to... Figure 6 and Figure 7 The top of the energy buffer controller 2 is equipped with a connecting frame 20 via a mounting structure 18, and two top covers 15 are mounted on the top of the connecting frame 20.
[0062] The top cover 15 covers the top of the energy cache controller 2 for protection. The installation structure 18 adopts a plug-in quick-release structure, which can be reinforced with bolts if necessary. The site where the mobile energy storage charging system is installed needs to be equipped with a monitoring system that can detect fires.
[0063] Please refer to Figure 6 and Figure 7 Both sides of the connecting frame 20 are equipped with diversion pipes 16, and a row of nozzles 17 are installed on the outer surface of the diversion pipes 16 near one side. One end of each diversion pipe 16 is fixedly connected to a connecting pipe 19.
[0064] The nozzles 17 are positioned at a 45-degree angle to the ground.
[0065] Please refer to Figure 6 A storage structure 12 is installed on the top of the mounting base 1, and a conveying structure 14 is installed on the top of the storage structure 12. A conveying pipe 13 with a three-way connector 21 is installed at the outlet of the conveying structure 14.
[0066] The two outlets of the three-way connector 21 are respectively connected to one end of the two connecting pipes 19. The storage structure 12 includes a shell, materials that can be stored for fire extinguishing in electrical applications, and electrically controllable valves and monitoring equipment. The conveying structure 14 includes a shell and a pump for conveying fire extinguishing materials. The fire extinguishing principle can use sodium bicarbonate.
[0067] Compared with related technologies, the charging device based on distributed mobile energy storage provided by this utility model has the following beneficial effects:
[0068] To enhance the safety of the energy storage charging system during high-temperature charging, a connecting frame 20 is mounted on top of the energy buffer controller 2 via an mounting structure 18. A shunt pipe 16 with multiple nozzles 17 is installed on each side of the connecting frame 20. Through the cooperation of a conveying structure 14, a three-way connector 21, and a connecting pipe 19, fire extinguishing materials from the storage structure 12 are sprayed out. In the event of a fire in the energy storage charging system, the fire can be extinguished promptly. In actual use, when the monitoring equipment installed on-site detects a fire around the corresponding energy buffer controller 2, the solenoid valve in the storage structure 12 automatically opens, cooperating with the conveying structure 14 to deliver fire extinguishing materials to the nozzles 17 for timely fire suppression around the energy buffer controller 2. This automatic fire suppression significantly improves the safety of the energy storage charging system under high-temperature conditions.
