Description

Technical Field

[0001] This utility model relates to the field of battery technology, specifically a high-rate lead-acid battery. Background Technology

[0002] High-rate batteries refer to batteries with high energy output capabilities, typically able to release a large amount of electrical energy in a short time to support high-load operation. High-rate batteries usually employ a multi-plate structure. This design increases the reaction area of ​​the plates, thereby improving the utilization rate of active materials and the current density per unit area, thus enhancing high-current discharge performance. Furthermore, high-rate batteries require relatively high electrolyte densities, and the amount of lead paste coating on the plates should also be appropriately increased. These structural characteristics determine that the assembly compactness of high-rate lead-acid batteries is much higher than that of conventional products, resulting in greater heat dissipation challenges. Summary of the Invention

[0003] The technical problem to be solved by this invention is: how to improve the heat dissipation structure of high-rate lead-acid batteries.

[0004] To achieve the above technical objectives, the present invention adopts the following technical solution:

[0005] A high-rate lead-acid battery includes an electrode group, a busbar, a tank, compartments, upright plates, a base plate, through holes, vertical ribs, horizontal ribs, notches, and protrusions. The electrode group has a busbar, and the tank has several compartments. The electrode group is loaded in the compartments, and the busbar on the electrode group is positioned above the upper end of each compartment. Two upright plates are located on the left and right sides of the top surface of the base plate, respectively. The two upright plates and the base plate together form the electrode group compartment, which is loaded into the battery compartment. The tank is loaded into the electrode group compartment. The upright plates and the base plate have several through holes. The outer side of the upright plates has several parallel vertical ribs and several parallel horizontal ribs. The horizontal ribs have notches in the middle, and both ends of the horizontal ribs protrude beyond the upright plates to form protrusions.

[0006] Preferably, a slot is provided on the inner wall of the battery compartment, and the horizontal rib is inserted into the slot.

[0007] Preferably, the protrusion presses against the inner wall of the battery compartment.

[0008] Preferably, the notch is triangular or trapezoidal, and the notch is located between the horizontal rib and the vertical plate.

[0009] Preferably, several heat dissipation holes are provided on the side wall of the compartment.

[0010] In the above technical solution, the electrode group is an energy storage module, and the busbar is its existing structure. In this utility model, the electrode group and the busbar themselves can adopt conventional structures. The tank is used to accommodate the electrode group. This utility model divides the tank into several compartments, so multiple electrode groups can be integrated and loaded into this utility model to achieve a modular structure. The upright plate and the bottom plate constitute the electrode group tank, which is used to support the tank body. The electrode group tank is loaded into a separate battery tank, thus forming the battery assembly structure. The through holes on the upright plate and the bottom plate serve a heat dissipation function. The vertical and horizontal ribs provide structural reinforcement to the electrode group tank. At the same time, the horizontal ribs can serve as the outward protrusion structure of the electrode group tank. The horizontal ribs themselves and their protrusions can be used to fit against the inner wall of the aforementioned battery tank. The notch gives the middle of the horizontal rib a certain degree of elasticity, making it easy to insert the electrode group tank into the battery tank when loading it. In addition, heat dissipation holes can be added to the tank body to further ensure the heat dissipation effect.

[0011] This invention provides a high-rate lead-acid battery. The technical solution incorporates a novel heat dissipation structure designed around the battery's assembly characteristics. Simultaneously, it features a modular loading structure for the energy storage unit and improves the external support structure of the electrode group slots. This invention helps improve the heat dissipation performance of high-rate lead-acid batteries while ensuring assembly stability and enhancing their high-current discharge performance.
