[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Reference Figure 1 - Figure 6 This embodiment provides a distributed optical storage and charging integrated mobile power supply. The mobile power supply is composed of the following components, including a power supply shell 10, which is composed of a base 101 and a cover plate 102. An external output interface 11 and a mains power interface 12 are respectively provided on both sides of the base 101. The external output interface 11 provides a power output interface for external loads, which can meet the power needs of different devices and provide power to various electrical devices conveniently and quickly. The mains interface 12 connects the system to the mains power grid, allowing the mains power to be fed into the system when necessary as a supplementary energy source for photovoltaics and energy storage, ensuring stable operation of the system under any circumstances, and also feeding excess power back to the mains power grid. A charging device 13 and an energy storage device 14 are fixedly installed on the base 101. The charging device 13 enables the power bank to provide charging services for devices such as electric vehicles, and can perform corresponding charging control and management according to the charging needs of different devices to achieve an efficient and safe charging process. The energy storage device 14 is used to store the excess electrical energy generated by the photovoltaic panel 17. When the photovoltaic panel 17 generates insufficient power or there is no sunlight, the stored electrical energy can be released to ensure the stable operation of the system. The capacity and charging and discharging performance of the energy storage device 14 are crucial to the reliability of the entire power system. Inverter 15 and energy management platform 16 are respectively mounted on base 101; Inverter 15 converts the DC power output from photovoltaic panel 17 into AC power, making it compatible with mains interface 12 and external output interface 11, providing power support for AC loads. At the same time, inverter 15 also has control and protection functions to ensure stable power conversion and safe operation of the system. The energy management platform 16 centrally manages and controls the entire system, enabling effective coordination and optimized control of photovoltaic, energy storage, charging devices, and mains power. Its main functions include: Inverter 15 Efficiency Control: Adjusts and optimizes the inverter's operating parameters to improve power conversion efficiency and system performance.

[0017] Energy storage power supply strategy: Based on the state of charge of the energy storage device 14 and the system load, a reasonable energy storage charging and discharging strategy is formulated to ensure the efficient utilization of the energy storage device 14 and the stable operation of the system.

[0018] Charging device 13 management: Monitor and manage the operating status of charging device 13, control parameters such as charging current and voltage, and realize intelligent charging of electric vehicles and other equipment.

[0019] Mains power management: Monitors the status of mains power access and grid parameters to ensure safe switching and stable operation between mains power and the system, and dispatches and controls power according to grid demand.

[0020] Geographic Information Management: By combining geographic information data, the system's geographical location and environmental conditions are analyzed and managed to optimize system configuration and operation strategies, thereby improving the system's adaptability and reliability. The photovoltaic panel 17 is mounted on the top of the cover plate 102 via the mounting assembly 18; The photovoltaic panel 17 serves as the energy input source for the system, converting solar energy into DC power to provide renewable and clean energy for the entire system. The generated power can be directly supplied to the load or charged to the energy storage device 14 via the charging device 13.

[0021] The power supply casing 10 is also equipped with a ventilation component 19 that can dissipate heat from the internal environment.

[0022] Under light conditions, such as Figure 7 As shown in the diagram, the photovoltaic panel 17 absorbs sunlight and converts solar energy into direct current (DC) power, which is then converted into alternating current (AC) power by the inverter 15. This provides power support for various devices within the power system and external loads. When the power generated by the photovoltaic panel 17 exceeds the system load demand, the excess power is charged by the charging device 13 to the energy storage device 14, storing the power in the form of chemical energy, etc. When the photovoltaic panel 17 generates insufficient power or there is no sunlight, the energy storage device 14 converts the stored DC power into AC power through the inverter 15 and releases it to supply the load, ensuring stable system operation. The charging device 13 automatically adjusts the charging parameters according to the charging needs of electric vehicles and other equipment and the battery status, so as to realize intelligent charging control, improve charging efficiency and battery life; the energy management platform 16 monitors and analyzes the operating status and energy flow of each device in the system in real time, and coordinates and controls the photovoltaic, energy storage, charging and other devices as well as the mains power according to the preset control strategy and optimization algorithm, so as to realize the optimized energy allocation and efficient operation of the system. The system is connected to the mains power grid through the mains power interface 12. When photovoltaic and energy storage cannot meet the load demand, it automatically switches to the mains power supply mode to ensure uninterrupted operation of the system. When the system generates excess power, it can feed the excess power back to the mains power grid through the mains power interface 12 to achieve rational use of energy and maximize economic benefits.

[0023] In more detail, the charging device 13 consists of a charging control module, a protection device, and a communication module. A charging interface is installed on one side of the charging device 13 for connecting to external electrical equipment.

[0024] In more detail, the energy storage device 14 consists of a battery pack, a battery management system, and a communication module. The energy storage device 14 is also equipped with a fuse, which can cut off the circuit in milliseconds in case of short circuit, reverse connection, or grounding, to prevent the battery from "thermal runaway" and catching fire.

[0025] Reference Figure 4 - Figure 6 Specifically, in order to install the photovoltaic panel 17, an installation assembly 18 is provided. The installation assembly 18 includes a mounting bracket 181 that is installed on the top of the cover plate 102 by screws. Several mounting slots 182 are equally spaced on the mounting bracket 181. A slide 183 is placed inside the mounting bracket 181. The slide 183 is connected to the cover plate 102 by screws, and the screws are located between the mounting slots 182. The slide 183 can be installed at any position on the mounting bracket 181 through the several mounting slots 182.

[0026] In more detail, the top of the slide 183 has an insertion hole 184, the limit bracket 185 is placed on the top of the slide 183, and the bolt 186 is threaded onto the limit bracket 185. The size of the insertion hole 184 is adapted to the bolt 186.

[0027] More specifically, one end of the bolt 186 extends into the insertion hole 184, thereby fixing the limiting frame 185. The limiting frame 185 is provided with a rubber pad, which can protect the photovoltaic panel 17 and increase the friction between the photovoltaic panel 17 and the limiting frame 185. The photovoltaic panel 17 is installed at the top of the mounting frame 181 and is located between several limiting frames 185. When installing the photovoltaic panel 17, the photovoltaic panel 17 is placed at the top of the mounting frame 181, and then the slide 183 is placed on the mounting frame 181 and located at the edge of the photovoltaic panel 17. Then, the limiting frame 185 is placed at the top of the slide 183, so that the limiting frame 185 contacts the edge of the photovoltaic panel 17 through the rubber pad. Then, the limiting frame 185 and the slide 183 are fixed by rotating the bolt 186, thereby pressing and fixing the photovoltaic panel 17.

[0028] In more detail, the ventilation assembly 19 includes a fan 191 fixedly mounted on the base 101. Heat dissipation holes 192 are respectively opened on both sides of the base 101, and ventilation holes 193 are also opened on the cover plate 102. Air can circulate in the power supply housing 10 through the heat dissipation holes 192 and ventilation holes 193. At the same time, the rotation of the fan 191 can increase the air flow rate, thereby dissipating heat more quickly.
