[0002] With the rapid development of new energy technologies and the widespread application of distributed energy systems, energy storage devices are becoming increasingly important in microgrid systems. Energy storage devices, as a device that can effectively store electrical energy and release it as needed, play a key role in balancing power supply and demand, improving power system stability, and optimizing grid operation. In household application scenarios, energy storage devices usually integrate core components such as battery management systems (BMS) and bidirectional inverters to store excess power from renewable energy sources such as solar photovoltaics and wind power or the city power grid for use by household loads or to provide emergency power in the event of a grid failure.

[0003] However, in the prior art, energy storage devices generally have the following problems: First, due to the diverse and complex working environment, especially in an environment with high humidity, moisture may cause the performance of the battery pack inside the energy storage device to degrade, shorten its life, and even cause safety hazards. Most traditional energy storage devices lack an effective monitoring and control mechanism for internal humidity, and are unable to promptly detect and eliminate the risk of excessive humidity. Secondly, if the heat generated by the energy storage device during long-term high-load operation cannot be quickly and effectively dissipated, it will affect the working efficiency and service life of the battery pack, and the existing heat dissipation structure and method may not achieve a comprehensive and uniform cooling effect.

[0031] In order to make the purpose, technical solution and advantages of the implementation mode of the present invention clearer, the technical solution in the implementation mode of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the implementation mode of the present invention.

[0032] like Figure 1 , Figure 3 , Figure 5 As shown, it is an example diagram of a first embodiment of a novel microgrid household-level energy storage device provided by the utility model. In this embodiment, it includes a main body 10, a handle 30 is arranged on the top of the main body 10, a fan 20 is arranged inside the main body 10, wherein a plurality of electrodes 12 are also installed at the bottom of the main body 10, and the plurality of electrodes 12 are respectively fixed at the corners of the bottom of the main body 10, asbestos material is embedded at the midpoint of the connecting line of the electrode 12, and two electrodes 12 are connected to a humidity alarm;

[0033] The side wall of the main body 10 is provided with ventilation holes 11 .

[0034] In the microgrid household-level energy storage device of the present invention, the cooling fan model used is a high-efficiency and energy-saving DC brushless motor fan. The specific model can be selected according to actual needs and market supply conditions, for example: FAN-XYZ1234 series. This series of fans has the characteristics of low noise, long life and intelligent speed regulation, and can meet the strict requirements of internal temperature management of the energy storage device.

[0035] It should be noted that in the microgrid household energy storage device of the present invention, the humidity sensor model used is a high-performance humidity detection device recognized by the industry, such as: HIH-4000 series humidity sensor. This series of sensors has the characteristics of high precision, fast response and good long-term stability, and can accurately monitor and feedback the humidity changes at the bottom of the energy storage device.

[0036] The electrodes can be made of corrosion-resistant and conductive materials, such as stainless steel 316L or gold-plated copper, and the installation position in the asbestos medium must be accurate to ensure the sensitivity and accuracy of humidity sensing.

[0037] Among them, in the above technical solution, the humidity sensor is fixedly arranged on the outer side wall of the shell of the main body 10.

[0038] like Figure 2 , Figure 4 As shown, further, in the above technical solution, there are multiple ventilation holes 11, and the multiple ventilation holes 11 are arranged in an array on the left and right side walls of the main body 10.

[0039] Furthermore, in the above technical solution, a dustproof net is fixedly installed on the inner side of the ventilation hole 11 to prevent dust and foreign matter from entering into the interior of the main body 10 .

[0040] Furthermore, in the above technical solution, the handle 30 is rotatably connected to the main body 10 via a rotating shaft.

[0041] The energy storage device and the fan are connected by a precise and reliable shaft connection structure. Specifically, a bearing seat is provided at a preset position inside the energy storage device, and the end of the fan motor shaft is embedded in the bearing seat and fixedly connected to it through a high-strength metal shaft. Anti-loosening gaskets and locking nuts are installed at both ends of the shaft to ensure that the fan remains stable and does not shift or loosen during high-speed operation. At the same time, in order to reduce the impact of vibration on the entire energy storage device, the shaft system is also equipped with shock-absorbing components, such as rubber buffer pads or spring shock absorbers, to absorb the vibration generated when the fan is running, thereby improving the overall operation stability and reliability of the equipment. In addition, the power cable of the fan is safely and reliably connected to the circuit board in the energy storage device through a waterproof connector, ensuring the safety and stability of the fan power supply and control signal transmission.

[0042] Furthermore, in the above technical solution, the main body 10 is a rectangular structure, the height of the main body 10 is 120 to 160 cm, the width is 60 to 80 cm, and the thickness is 40 to 60 cm.

[0043] Furthermore, in the above technical solution, the main body 10 is an integrated aluminum alloy body.

[0044] Furthermore, in the above technical solution, the number of the electrodes 12 is 2, which are respectively arranged at the diagonal lines of the bottom corners of the main body.

[0045] Furthermore, in the above technical solution, an exhaust hole is also designed at the bottom of the main body 10 to discharge the internal heat of the main body 10 and improve the heat dissipation efficiency through directional airflow.

[0046] Furthermore, in the above technical solution, a dustproof net is fixedly installed on the inner side of the air extraction hole.

[0047] like Figure 1 As shown, it is an example diagram of a second embodiment of a novel microgrid household-level energy storage device provided by the utility model. In this embodiment, it includes a main body 10, a handle 30 is arranged on the top of the main body 10, a fan 20 is arranged inside the main body 10, wherein a plurality of electrodes 12 are also installed at the bottom of the main body 10, and the plurality of electrodes 12 are respectively fixed at the corners of the bottom of the main body 10, asbestos material is embedded at the midpoint of the connecting line of the electrode 12, and two electrodes 12 are connected to a humidity alarm;

[0048] The side wall of the main body 10 is provided with ventilation holes 11 .

[0049] The connections to build the humidity sensor circuit are as follows:

[0050] Two electrodes are arranged at the bottom of the energy storage device, marked as electrode A and electrode B respectively, the two electrodes are separated by a certain distance through an insulating material (such as polytetrafluoroethylene), and asbestos material is embedded in the midpoint of the line connecting the two electrodes as a humidity sensing medium.

[0051] The asbestos material is in contact with the two electrodes but not directly connected. When the ambient humidity increases, the conductivity of the asbestos increases after absorbing moisture, which reduces the resistance between electrode A and electrode B.

[0052] Electrode A and electrode B are each connected to a signal processing module inside the humidity alarm through a wire. The module includes a precision resistor voltage divider network and an amplifier circuit for converting resistance changes caused by humidity changes into electrical signals.

[0053] The humidity alarm is also equipped with a preset threshold comparison circuit. When the electrical signal generated by the humidity sensing circuit exceeds the preset threshold, the alarm activates the sound and light alarm function to remind the user to take dehumidification measures in time.

[0054] Specifically, the principle of the utility model is as follows: the energy storage device of the utility model forms a set of efficient heat dissipation system by scientifically arranging fans, air vents and exhaust holes. After the fan is started, air enters from the air vents on the side wall of the energy storage device, passes through the internal battery module, and is discharged from the exhaust holes at the bottom with heat, thereby achieving the purpose of rapid heat dissipation; in terms of humidity detection, asbestos material, whose physical properties change with humidity, is used as a humidity sensing medium, and is placed at the midpoint of the line connecting two electrodes. When moisture appears at the bottom of the energy storage device, the conductivity of the asbestos material is enhanced after absorbing moisture, so that the resistance between the two electrodes is reduced, triggering the humidity alarm to sound an alarm. This design principle is based on the working characteristics of the humidity sensor and cleverly uses asbestos material to realize humidity monitoring, which not only saves the cost of special humidity sensors, but also ensures the accuracy and real-time performance of humidity monitoring, providing a strong guarantee for the safe operation of household-grade energy storage devices.
