[0002] With the increasingly widespread application of new energy sources, the importance of energy storage battery packs is becoming increasingly prominent. However, different scenarios have different power requirements, such as home energy storage and industrial backup power, making it difficult for fixed-capacity battery packs to adapt flexibly. Adjustable-capacity energy storage battery packs have emerged to address this need. They can precisely adjust power output and storage capacity according to actual power consumption, improving energy utilization efficiency, reducing waste, better matching diverse power usage scenarios, helping to achieve scientific allocation and efficient utilization of energy, and driving the further development of the energy storage industry.

[0003] Existing energy storage battery packs rely solely on external air for heat dissipation during use, lacking additional heat dissipation structures.

[0018] The present invention, through the arrangement of a fixed plate, rotating roller, heat circulation belt, gear drive belt, and fixed rod, achieves the following advantages:

[0019] Efficient heat dissipation ensures battery performance and lifespan: The rotating operation of the thermal circulation belt, in coordination with various components, achieves comprehensive, dynamic, and uniform heat absorption and transfer to the battery pack body, effectively preventing localized heat accumulation and keeping the battery pack in a suitable operating temperature environment.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] Please see Figure 1-5 This utility model provides a technical solution for an energy storage battery pack with adjustable power: an energy storage battery pack with adjustable power, including a battery pack body 2;

[0032] A front panel 1 is provided at the front side of the battery pack body 2, and power interfaces 5 are respectively provided at both ends of the front side of the front panel 1.

[0033] Multiple connection ports 10 are provided on the rear side of the battery pack body 2;

[0034] Fixing plates 6 are respectively installed at the middle positions of the left and right ends and the front and rear ends of the battery pack body 2;

[0035] A rotating roller 9 is provided at the middle position of the two fixing plates 6 on one side of the battery pack body 2, and a gear 7 is provided at the front side of the rotating roller 9;

[0036] A heat circulation belt 8 is provided on the outer side of the two rotating rollers 9.

[0037] The battery pack body 2 has four fixing rods 3 at the top and bottom corners, and the ends of the fixing rods 3 are cut in an arc shape. The front plate 1 has a handle 4 bolted to the outer side of the middle.

[0038] In this embodiment, the battery pack body 2 houses numerous battery cells that store electrical energy through electrochemical reactions. The battery management system monitors and controls these cells to ensure stable and safe operation. The front panel 1 serves as a front-end protective structure, protecting the internal components of the battery pack body 2 from external physical impacts and providing a stable support for the power interface 5, facilitating the connection of external devices for power input and output. During the charging phase, the power interface 5 connects to an external charger. The charger transmits electrical energy through the power cord to this interface, which then enters the battery pack body 2. Charging follows the charging strategy of the battery management system to prevent overcharging and other abnormalities. During power supply, it serves as an output port connected to the power input of the device, driving the device to operate normally.

[0039] Power regulation is primarily achieved through multiple connection interfaces 10 on the rear side of the battery pack body 2. When a higher output voltage is required, multiple battery pack bodies 2 can be connected in series via the connection interfaces 10. This means connecting the positive terminal of one battery pack body 2 to the negative terminal of the next battery pack body 2, with the negative terminal of the first battery pack body 2 serving as the overall negative terminal and the positive terminal of the last battery pack body 2 serving as the overall positive terminal for power output. After this series connection, the total voltage is the sum of the voltages of each battery pack body 2, while the capacity remains unchanged, meeting the power supply requirements of high-voltage electrical equipment. To increase the overall power capacity, the connection interfaces 10 can be used for parallel connection. This involves connecting the positive terminals of each battery pack body 2 together as the overall positive terminal and connecting the negative terminals together as the overall negative terminal for power output. The total capacity after parallel connection is the sum of the capacities of each battery pack body 2, and the voltage is the same as that of a single battery pack body 2. This is suitable for electrical equipment with high capacity requirements and requiring long-term power supply.

[0040] These structures work together, with the battery pack body 2 as the core, and different interfaces to achieve different connection combinations, thereby enabling flexible adjustment of power in terms of voltage, capacity, etc., while ensuring normal energy storage, output and stable use of the battery pack as a whole, so that it can better adapt to the needs of various electrical devices and different application scenarios.

[0041] like Figure 1-5 As shown, four fixed plates 6 are connected to the battery pack body 2 by bolts. The rotating roller 9 is connected to the fixed plates 6 by nesting. The rotating roller 9 can rotate within the two fixed plates 6. A limit protrusion is provided on the rear side of the rotating roller 9. The gear 7 is connected to the front side of the rotating roller 9 by welding. A drive belt 11 is connected to the outside of the gear 7. An external motor is connected to one side of the drive belt 11 as a drive source. The drive belt 11 is connected to the gear 7 by meshing. The drive belt 11 can be a chain structure. The heat circulation belt 8 is in close contact with the upper and lower sides of the battery pack body 2. The heat circulation belt 8 is made of carbon fiber composite material.

[0042] Preferably, the heat circulation belt 8 is made of carbon fiber composite material because carbon fiber itself has high thermal conductivity, which can efficiently conduct heat and ensure that heat can be transferred quickly within the belt. At the same time, carbon fiber composite material also has good strength and toughness, and is not prone to damage or breakage during long-term rotation. It can adapt to the complex operating environment of the battery pack body 2 and the rotation conditions driven by the roller 9, ensuring that the heat circulation belt 8 can stably perform its heat dissipation function over a long period of time.

[0043] Preferably, the user connects an external motor as a drive source to the drive belt 11. The drive belt 11 drives the gear 7 to rotate via a meshing connection (such as a chain structure meshing with a gear 7). Since the gear 7 is welded to the front side of the rotating roller 9, the rotation of the gear 7 drives the rotating roller 9 to rotate flexibly around its axis within the fixed plates 6 located at the middle positions of the left and right ends and the front and rear ends of the battery pack body 2, which are bolted together. The limiting protrusion on the rear side of the rotating roller 9 ensures that there is no axial displacement during its rotation. The heat circulation belt 8, which is made of carbon fiber composite material and is in close contact with the upper and lower sides of the battery pack body 2, rotates around the outside of the battery pack body 2 under the friction generated by the rotation of the rotating roller 9, constantly changing the contact surface with the battery pack body 2 to absorb heat. Meanwhile, the fixing rods 3 located at the four corners on the upper and lower sides of the battery pack body 2 and with arc-shaped cut ends, play a role in raising the battery pack body 2 when the battery pack is placed in the cabinet or other installation position, preventing the heat circulation belt 8 from contacting the inner surface of the cabinet during rotation, thereby ensuring that the heat circulation belt 8 can rotate normally and continuously around the battery pack body 2, maintaining the stable operation of the entire heat dissipation system, and thus realizing the coordinated operation of the battery pack power regulation function and good heat dissipation function.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
