[0040] Please refer to Figures 1 to 17 As shown, a mobile energy storage integrated machine of this utility model includes:

[0041] The mobile enclosure contains a parallel arrangement of energy storage compartments and a control compartment. The control compartment includes a power control area, a power conversion area, and a power output and input area arranged from bottom to top.

[0042] The bottom of the energy storage compartment is equipped with a PC insulating strip, the top of the energy storage compartment is equipped with AB structural adhesive, and the battery cell module is located between the PC insulating strip and the AB structural adhesive.

[0044] The power conversion area is equipped with PCS inverter components;

[0045] The power input / output area is equipped with an expansion dock, communication connectors, and fast charging and photovoltaic connector components.

[0046] As can be seen from the above description, the beneficial effects of this utility model are as follows: A mobile energy storage integrated unit integrates an inverter device inside a cabinet, enabling charging and discharging anytime and anywhere; a PC insulating strip is pasted at the bottom of the energy storage compartment, and AB structural adhesive is applied to the inner surface of the energy storage compartment. The assembled battery cell modules are placed on the upper surface of the PC insulating strip and pressed and fixed with the AB structural adhesive, so that the modules are tightly fixed to the cabinet. The combined use of the PC insulating strip and AB structural adhesive isolates the modules from the sheet metal cabinet, achieving insulation between the modules and the cabinet, and improving product safety; the overall layout of the cabinet adopts an ultra-thin layout scheme, making the overall thickness of the cabinet thinner and lighter, thus taking up less space and making it convenient for home placement; the integrated structural design scheme makes the fixing structure of the inverter and BMS lighter and greatly reduces manufacturing costs; all important internal components adopt a modular design, making product installation or replacement simpler, eliminating the need for extensive disassembly and reassembly, and improving production and maintenance efficiency; The power strip features a communication connector on its side, facilitating the exchange of power conversion and control information between the enclosure and the outside world, thus simplifying after-sales maintenance.

The photovoltaic charging port allows users to connect photovoltaic panels outdoors for timely power replenishment of the energy storage box, improving product usability. The charging port has been expanded to meet various charging needs. While a standard charging efficiency interface is used under normal circumstances to enhance the safety of the charging equipment, a fast charging port is also provided for rapid power replenishment in urgent situations, improving charging efficiency and meeting user power requirements. In addition to the mains power input port, the product also features a photovoltaic input interface, allowing users to connect photovoltaic panels outdoors for power replenishment, further enhancing product usability and meeting power requirements in various complex situations.

[0047] In an alternative embodiment, the mobile enclosure is provided with a U-shaped bracket for installing the BMS, and the U-shaped bracket has an air duct for exhausting the PCS inverter components.

[0048] As described above, the BMS, fuses, and circuit breakers are all fixed to the BMS mounting bracket using bolts and press-fit nuts or insulating posts.

[0049] To further improve the exhaust effect, a groove-shaped air duct formed by PC insulating sheets is set at the connection of the Z-shaped BMS mounting bracket at the inverter air outlet, and is fixed to the BMS mounting bracket by rivets. This allows the hot air from the inverter exhaust port to be directly conducted to the outside, avoiding heat leakage inside the enclosure from affecting the components.

[0050] In an optional embodiment, an EVA foam pad is provided between the PCS inverter elements and the mobile housing.

[0051] As can be seen from the above description, EVA foam pads are installed at all contact points between the PCS inverter and the enclosure to prevent scratches and reduce vibration on the contact surfaces, thereby increasing product redundancy and improving production efficiency.

[0060] In an optional embodiment, the number of battery cell modules is greater than or equal to two, and the battery cell modules are connected in series via aluminum busbars.

[0061] As can be seen from the above description, the energy storage bin is equipped with a series aluminum module, and the two modules are connected and fixed by bolts to achieve electrical conduction. The energy of the energy storage bin is output and input through the total positive and total negative output terminals of the modules.

[0062] In an optional embodiment, the mobile housing is equipped with a handle and casters.

[0063] As can be seen from the above description, based on the existing products, high-energy-density energy storage boxes have been equipped with self-locking casters and fixed casters that offer good passability and high load-bearing capacity. A handle is also provided on the top of the box to facilitate the movement and transport of the equipment.
