[0034] In one embodiment, refer to Figures 1 to 3As shown, the energy storage charging cabinet provided by the present application comprises a battery box 1, an inverter 2, a distribution box 3 and a charging gun 4. The battery box 1 has a first side 5 in the length direction X and a second side 6 in the width direction Y. The inverter 2 and the distribution box 3 are arranged on the first side 5 of the battery box 1 in the height direction Z, and the battery box 1 and the inverter 2 are electrically connected with the distribution box 3. The distribution box 3 is provided with an external power supply interface 7. The charging gun 4 is electrically connected with the distribution box 3 and hung on the second side 6 of the battery box 1.

[0035] In this embodiment, the battery box 1 is the core component of the energy storage charging cabinet, and can store batteries to be charged. The capacity of the battery can be designed according to actual needs, for example, it can be 32kWh.

[0036] The inverter 2 is installed on the first side 5 of the battery box 1 in the length direction X, which can be the front side. The inverter 2 is responsible for the conversion between alternating current and direct current. The position of the inverter 2 is selected to reduce the length of the wire, thereby simplifying the internal wiring and improving the efficiency. The power of the inverter 2 can be designed according to actual needs, for example, it can be 10kW.

[0037] The distribution box 3 is also located on the first side 5 of the battery box 1 and is electrically connected with the battery box 1 and the inverter 2. The distribution box 3 is the power distribution center of the entire device and is provided with an external power supply interface 7, which can access the mains or other forms of external power supply.

[0038] The charging gun 4 is arranged on the second side 6 of the battery box 1 in the width direction Y, which can be the right side, and is connected with the distribution box 3 through a cable. The charging gun 4 can provide charging service for external devices such as electric vehicles or household appliances. Such design allows users to conveniently take and return the charging gun 4, and avoids the problem of cable entanglement, thereby improving the user experience. The power of the charging gun 4 can be designed according to actual needs, for example, it can be 9.6kW.

[0039] The inverter 2 and the distribution box 3 of the present application can be arranged on the front side of the battery box 1 in the height direction Z, i.e. the inverter 2 and the distribution box 3 are designed to be stacked in front of and behind the battery box 1, and the charging gun 4 is placed on the right side of the battery box 1. Such layout not only makes the overall structure compact, but also makes the installation and use more simple, because the mutual interference between different components is reduced.

[0040] Charging process: when the energy storage charging cabinet is connected to the external power supply, the power is input through the external power supply interface 7 of the distribution box 3. If the external power supply is alternating current, it will be converted into direct current suitable for battery storage by the inverter 2; if the external power supply is already direct current, it can be directly charged to the battery.

[0041] Discharge process: when it is necessary to use the energy stored in the battery, the direct current can be converted into alternating current output by the inverter 2, or directly supplied in the form of direct current to the device supporting direct current input.

[0042] It can be understood that the distribution box 3 as a device for power distribution and management has a safety protection function, which can ensure that there is no overload, short circuit and other problems during charging and discharging, and ensure the safety of use.

[0043] Therefore, the energy storage charging cabinet provided by the embodiment of the application has reasonable layout of each component, and users can easily access external power supply and charge other devices using the charging gun 4, thereby improving the convenience and efficiency of use, achieving efficient, safe and reliable energy storage and charging management, and simplifying the installation and maintenance process.

[0044] In one embodiment, referring to Figure 2 , the battery box 1 is provided with a socket 8 on the upper part of the second side 6 in the width direction Y, and the charging gun 4 is plugged into the socket 8.

[0045] Specifically, when it is necessary to use the charging gun 4 to charge external devices, the user pulls out the charging gun 4 from the socket 8 on the right side of the battery box 1, and after use, plugs the charging gun 4 back into the socket 8 to ensure its stable storage and keep the device tidy and orderly. Such a design simplifies the management and storage of the charging gun 4, improves the convenience and safety of use.

[0046] In one embodiment, referring to Figure 1 and Figure 3 , the side of the distribution box 3 is provided with a containing chamber 9, and the containing chamber 9 has an openable or closable cover plate 10; the external power supply interface 7 includes a plug 11, and the plug 11 is arranged in the containing chamber 9 and used for connecting a direct current power supply.

[0047] In this embodiment, the containing chamber 9 can be located on the left side of the distribution box 3 to provide a dedicated storage space for the plug 11. The design of the containing chamber 9 can prevent dust, water and other external factors from damaging the plug 11, thereby prolonging the service life of the device.

[0048] The cover plate 10 can be rotatably connected to the opening of the containing chamber 9 through a rotating shaft, allowing the user to conveniently open or close the containing chamber 9. This design ensures that the plug 11 can be effectively protected when the external power supply is not needed, while not affecting the appearance and overall layout.

[0049] Specifically, when power is needed from an external DC power source (such as solar panels), the user first opens the cover 10 and then inserts the external DC power cable into the plug 11 inside the housing chamber 9. The distribution box 3 then distributes the input DC power to the battery box 1 for charging or other purposes. When there is no need for an external power source, the cover 10 is kept closed, which not only protects the plug 11 from physical damage but also reduces potential safety hazards caused by exposure.

[0050] Therefore, the distribution box 3 of this application embodiment cleverly combines functionality and practicality. By providing a receiving chamber 9 with a cover plate 10 to protect the plug 11, it ensures the safe operation of the equipment and improves the user experience. This design is particularly suitable for use in outdoor environments, effectively coping with various harsh conditions and ensuring the stable and reliable operation of the energy storage charging cabinet.

[0051] In one embodiment, refer to Figure 1 and Figure 3 As shown, the external power interface 7 includes a cable 12 that extends to the outside of the distribution box 3 for connecting to an AC power source.

[0052] Specifically, in addition to the built-in DC power plug 11, this application also includes a cable 12 extending from the distribution box 3 to the outside. The cable 12 can be equipped with a suitable plug or connector for connecting to an AC power source. This design allows users to connect the energy storage charging cabinet to the mains power grid or an AC power source such as a portable generator. The inverter 2 inside the distribution box 3 converts the received AC power into DC power to charge the battery box 1.

[0053] Understandably, this application supports both AC and DC power input methods, greatly expanding the application scenarios of the energy storage charging cabinet and making it suitable for more types of users and environments. The design of the external cable 12 allows users to easily connect different power sources in different locations, making it particularly suitable for outdoor activities, emergency power supply in emergencies, and remote areas without a fixed power grid. Regardless of the power source used, users only need to follow the corresponding steps to connect the cable 12 or plug 11 to complete the setup, without the need for complicated adjustments or additional tools.

[0054] Therefore, by adding an external cable 12 interface to support AC power input, the energy storage charging cabinet not only maintains the original DC power input capability, but also enhances its adaptability and flexibility, thereby meeting the diverse needs of different users.

[0055] In one embodiment, the inverter 2 is detachably connected to the first side 5 of the battery box 1.

[0056] In this embodiment, the inverter 2 and the battery box 1 can be assembled by means of bolts, buckles or the like, which makes the inverter 2 a separate module that can be conveniently removed or installed from the battery box 1 without affecting the functions of other components, effectively simplifying the installation process.

[0057] In one embodiment, referring to Figure 1 and Figure 4 , the first side 5 of the battery box 1 is provided with a first fastening hole 13; the inverter 2 is provided with a mounting bracket 14 adjacent to one side of the first side 5 of the battery box 1, and the mounting bracket 14 is provided with a second fastening hole corresponding to the first fastening hole 13, and the second fastening hole is connected with the first fastening hole 13 by a fastener 15.
