[0002] In today's society, batteries are widely used in various fields, such as electric vehicles, uninterruptible power supplies (UPS), and solar energy storage systems. With the continuous development of technology, the requirements for the performance and intelligence of battery charging and discharging equipment are also increasing.

[0003] Traditional battery charging and discharging devices suffer from numerous heat dissipation problems. Firstly, ineffective heat dissipation leads to excessively high battery temperatures during charging and discharging, affecting not only charging and discharging efficiency but also shortening battery life. For example, during fast charging of electric vehicles, if heat dissipation is insufficient, the battery temperature can rise sharply, potentially causing performance degradation or even safety hazards. Secondly, in traditional devices, dust and impurities from the air can easily enter the equipment during air intake cooling, adhering to the charging / discharging unit and other components. Accumulation of these impurities can affect normal operation, reducing stability and reliability. For instance, dust can clog the heat dissipation channels of electronic components, causing overheating and damage.

[0004] Furthermore, traditional battery charging and discharging devices are inconvenient to maintain and clean. Replacing or cleaning filters is often cumbersome, requiring significant time and manpower. This is a pressing issue for equipment that requires frequent use and maintenance.

[0005] Therefore, an intelligent charging and discharging device for storage batteries is invented to solve the problems mentioned in the background art. Utility Model Content

[0015] Reference Figure 1 , Figure 4One embodiment shown is as follows: The intelligent battery charging and discharging device mainly consists of a fixed housing 1 and a charging and discharging main body 2 installed inside it. The fixed housing 1 serves as the basic support structure of the entire device, with an exhaust vent at the top and an air inlet vent 3 at the bottom. A heat dissipation mechanism 4 is installed inside the air inlet vent 3, which works in conjunction with the air intake fan 8 at the bottom of the fixed housing 1 to dissipate heat from the charging and discharging main body 2. In this embodiment, the air intake fan 8 is fixed to the bottom of the fixed housing 1 by screws or clips. After being started, it draws in external cold air through the air inlet vent 3. The air flows through the heat dissipation mechanism 4, carrying the heat generated by the charging and discharging main body 2, and is then discharged from the exhaust vent at the top, forming an effective heat dissipation cycle. The four corners of the bottom of the fixed housing 1 are equipped with casters 9 using bolt connections or embedded installation, making the entire device more convenient to move, whether transferring between different workstations indoors or changing positions in outdoor work environments.

[0016] The implementation principle of the above embodiment is as follows: the suction force generated by the intake fan 8 is used to introduce cold air, which is then guided and assisted by the heat dissipation mechanism 4 to cool the charging and discharging body 2. The hot air is then discharged through the exhaust hole to achieve heat exchange. At the same time, the universal wheels 9 reduce the friction when the device moves, making it convenient to use the device in different locations.

[0017] Reference Figure 1 One embodiment shown is as follows: the heat dissipation mechanism 4 mainly consists of a limiting housing 5 and multiple filter plates 6. The limiting housing 5 is fixed inside the air inlet 3, and its fixing method can be welding, riveting, or engaging with a slot 10, etc. In this embodiment, a sliding groove is provided on the inner wall of the limiting housing 5, and sliders matching the sliding groove are provided on both sides of the multiple filter plates 6, thereby achieving a detachable connection. Each filter plate 6 has filter holes 7, and the size of the filter holes 7 gradually decreases when viewed from the air inlet direction. The connection between the limiting housing 5 and the air inlet 3 provides installation space for the filter plates 6; the detachable connection between the filter plates 6 and the limiting housing 5 facilitates the replacement and maintenance of the filter plates 6.

[0018] The implementation principle of the above embodiment is as follows: using the multi-stage filtration principle, when air enters, it first passes through the large-pore filter plate 6 to filter large particulate impurities, and then passes through the small-pore filter plate 6 to filter small particulate impurities, preventing dust and impurities from entering the device.

[0019] Reference Figure 5 , Figure 6One embodiment is shown in which several slots 10 are evenly distributed along the vertical direction on the limiting housing 5, and each slot 10 is tightly embedded in and connected to a filter plate 6. A magnetic pull block 11 is fixedly connected to one end of the filter plate 6 by adhesive, screws, or integral molding, while the limiting housing 5 is made of permanent magnet material. In this embodiment, when the filter plate 6 is embedded in the slot 10, the magnetic pull block 11 is attracted to the limiting housing 5 due to the permanent magnet characteristics of the limiting housing 5. The embedded connection between the slots 10 and the filter plate 6 ensures the accuracy of the filter plate 6's installation position; the attraction between the magnetic pull block 11 and the limiting housing 5 enhances the fixing effect of the filter plate 6.

[0020] The implementation principle of the above embodiment is as follows: the filter plate 6 is stably installed by positioning through the slot 10 and adsorption by the magnetic pull block 11. When it needs to be disassembled, the magnetic pull block 11 can be pulled, which is convenient for maintenance.

[0021] Reference Figure 1 , Figure 4 , Figure 6 One embodiment is shown as follows: Rotatable rotating shafts 12 are mounted on both sides of the bottom of the fixed housing 1 via bearing seats. Rotating cams 13 are fixedly welded onto the rotating shafts 12, with the top of the rotating cams 13 in close contact with the bottom of the limiting housing 5. A sliding groove 14 is formed at the bottom of the fixed housing 1, and the limiting housing 5 is slidably connected to the sliding groove 14 on both sides, allowing it to slide up and down within the sliding groove 14. Compression springs 15 are fixedly connected to both sides of the limiting housing 5 via welding, and the other end of the compression springs 15 is also welded and fixed to the fixed housing 1. A drive motor 16 is fixedly mounted at the bottom of the fixed housing 1 via bolts or brackets, and the output end of the drive motor 16 is fixedly connected to the rotating shafts 12 via a coupling or key. In this embodiment, when the drive motor 16 starts, it drives the rotating shafts 12 to rotate, which in turn drives the rotating cams 13 to rotate. The rotating cams 13 push the limiting housing 5 to slide rapidly up and down within the sliding grooves 14, and with the cooperation of the compression springs 15, the limiting housing 5 generates high-frequency vibration. The connection between the rotating shaft 12 and the fixed housing 1 enables the rotating shaft 12 to rotate stably; the connection between the rotating cam 13 and the rotating shaft 12 realizes the power transmission; the connection between the limiting housing 5 and the sliding groove 14 and the fixed compression spring 15 realizes the up-and-down movement and vibration function of the limiting housing 5.

[0022] The implementation principle of the above embodiment is as follows: the drive motor 16 drives the rotating cam 13 to rotate, which pushes the limiting housing 5 to move up and down to generate vibration, thereby causing the dust and impurities attached to the filter plate 6 and the inner wall of the limiting housing 5 to fall off, achieving the purpose of cleaning and making it easier to maintain a good filtration effect.

[0023] Reference Figure 4 , Figure 5One embodiment shown is as follows: the top of the intake fan 8 is fixedly fitted with a guide cavity 17 by means of screw connection, snap-fit ​​connection, or sealant bonding. A plurality of guide holes 18 are evenly distributed within the guide cavity 17. In this embodiment, after the intake fan 8 draws in air, the air directly enters the guide cavity 17, and the guide cavity 17 guides the air evenly to the charging / discharging body 2 through the guide holes 18. The connection between the intake fan 8 and the guide cavity 17 ensures airflow sealing; the design of the guide holes 18 allows air to be evenly distributed to all parts of the charging / discharging body 2. The implementation principle of the above embodiment is: by utilizing the structure of the guide cavity 17 and the guide holes 18, the air drawn in by the intake fan 8 is redistributed and guided, improving heat dissipation efficiency and uniformity.

[0024] Reference Figure 1 , Figure 3 , Figure 5 One embodiment is shown where multiple temperature sensors 19 are installed inside the fixed housing 1 at key heat-generating locations, such as near the charging / discharging body 2, using methods such as adhesive bonding, screw fixing, or mounting via slot 10. A control panel 20 is mounted on the top of the fixed housing 1 using screws or clips, and the temperature sensors 19 are electrically connected to the control panel 20 via wires. In this embodiment, the temperature sensors 19 monitor temperature changes inside the fixed housing 1 in real time and transmit the collected temperature data to the control panel 20 via wires. The control panel 20 analyzes and processes the received data and displays the temperature information on a screen in numerical or graphical form.

[0025] The working principle of this device is as follows: When the device is running, the intake fan 8 starts, drawing in outside air through the air inlet 3. The air passes through the filter plates 6 in sequence, with different pore sizes filtering layer by layer, preventing dust and impurities from entering the equipment. Next, the air enters the guide cavity 17, and is evenly blown onto the charging and discharging body 2 through the guide holes 18, carrying away heat before being discharged from the exhaust vent, thus completing the heat dissipation.

[0026] If cleaning is required, start the drive motor 16, which drives the rotating shaft 12 and the rotating cam 13 to rotate. The rotating cam 13 pushes the limiting housing 5 to slide up and down in the sliding groove 14. Under the action of the fixed compression spring 15, the limiting housing 5 vibrates rapidly, causing the dust and impurities attached to the filter plate 6 and the inner wall of the limiting housing 5 to fall off.

[0027] Throughout the process, temperature sensor 19 monitors the temperature inside the fixed housing 1 in real time and transmits the data to control panel 20. Based on the temperature data, control panel 20 can intelligently adjust parameters such as the speed of intake fan 8 to maintain the equipment operating at a suitable temperature, ensuring charging and discharging efficiency and equipment stability.

[0028] The working principle of this device has been explained through the above embodiments. These embodiments only illustrate several implementation methods of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
