Description

Technical Field

[0001] The utility model belongs to the technical field of lead-acid batteries, and in particular relates to an AGM lead-acid battery and a special tank body thereof. Background Art

[0002] AGM lead-acid battery is a valve-regulated lead-acid battery, in which the sealed type, lean liquid type, and tight assembly are the key to ensuring the quality of battery assembly. In AGM batteries, the plate must be in close contact with the AGM diaphragm, and the diaphragm is under a certain assembly pressure in the battery, which can inhibit the expansion of the positive electrode active material in the deep discharge cycle, otherwise it will cause the positive electrode active material to fall off, resulting in reduced conductivity and loss of discharge capacity, which directly affects the cycle life of the battery. With the improvement of industrial manufacturing level, factories can now manufacture thinner grids, and the development and research of new materials has greatly improved the utilization rate of active materials. In order to reduce costs and energy consumption, factories can use thinner and lighter plates to produce qualified batteries.

[0003] However, the battery is a standard part, and the exterior dimensions of length, width and height are designed according to the standard. After the change, it cannot be used in the market and cannot be installed in the reserved battery position of the existing vehicle. Therefore, it is necessary to ensure that the exterior dimensions of the tank are inconvenient. In order to ensure the battery assembly pressure without changing the dimensions, the current methods used are:

[0004] 1. Increase the thickness of the AGM separator, but this will increase the internal resistance of the battery and reduce performance.

[0005] 2. Add lining plates to imitate flooded batteries, but the assembly pressure of AGM batteries is high, adding lining plates is not conducive to production operations and has low efficiency. Summary of the invention

[0006] The utility model aims to solve the above-mentioned deficiencies of the prior art, thereby providing an AGM lead-acid battery and a special tank body thereof, the tank body can meet the size requirements and ensure the low-cost battery assembly quality.

[0007] The technical solution of the utility model is: a tank body of an AGM lead-acid battery, comprising a battery tank body;

[0008] The battery tank body is an open groove with an upper end opened and surrounded by a left side wall, a right side wall, a front side wall, a rear side wall and a bottom wall, and the two ends of the inner cavity of the open groove are separated into symmetrical occupying spaces by two partition walls;

[0009] A plurality of reinforcing ribs are evenly distributed side by side in the occupying space, and the plurality of reinforcing ribs are perpendicular to the partition wall and the left and right side walls of the battery slot body;

[0010] The two partition walls are divided into a plurality of cells capable of accommodating battery cells via partitions.

[0011] The middle parts of the two partition walls are parallel to the left and right side walls of the battery slot body, and the two end parts are gradually inclined toward the corresponding side walls of the battery slot body to form an inclined surface.

[0012] The two partition walls are divided into six 1*6 single grids by five partitions, and the five partitions are parallel to the left and right side walls of the battery slot body.

[0013] The two partition walls are divided into six 2*3 single cells by three partitions, two of which are parallel to the left and right side walls of the battery slot body, and the other partition is perpendicular to the left and right side walls of the battery slot body.

[0014] The upper end surface of the reinforcing rib is lower than the upper end surfaces of the four side walls of the battery container body.

[0015] The upper end surface of the reinforcing rib is 5 mm lower than the upper end surfaces of the four side walls of the battery container body.

[0016] An AGM lead-acid battery comprises a pole group, a battery cover and a tank body as described in the above technical solution, wherein the battery cover is buckled on the tank body and the pole group is accommodated in a single cell of the tank body.

[0017] The beneficial effect of the utility model is that after adopting the tank body, the factory can use thinner pole plates to produce batteries with qualified performance.

[0018] The use of thin separators improves the low-temperature discharge performance of batteries and enhances product competitiveness. The use of thin plates directly reduces the lead consumption of the entire battery, and the resulting material costs and energy consumption are greatly reduced, greatly saving factory costs.

[0019] The battery appearance bulging can be effectively alleviated by using the space buffer. Compared with the current practice of adding grid-like horizontal and vertical ribs on the left and right side walls of the battery to enhance the strength of the outer wall to resist expansion, the utility model also has ribs in the space to increase the strength. In addition, the inner layer is directly stressed and can alleviate part of the battery expansion force through deformation, and the expansion force acting on the outermost side is correspondingly reduced, thereby alleviating the overall appearance bulging problem.

[0020] The utility model is mainly used for producing AGM lead-acid batteries with high cost performance. BRIEF DESCRIPTION OF THE DRAWINGS
