A battery pack structure with single cells connected by pressure

Abstract

The invention discloses a battery pack structure in which single cells are connected by pressure, comprising at least two single cells, the single cells are stacked from bottom to top, and the plastic upper cover of the single cells has a current collector drawn from the battery groove The pole lug, and the riding reinforced U-shaped beam, the current collector lug is in contact with the riding reinforced U-shaped beam; it also includes a riding pole, a riding beam and an insulating pad, and the riding beam is provided with an aperture, and the uppermost single The horse riding of the battery is strengthened above the U-shaped crossbeam, the insulating pad is located under the lowermost single battery, the lower end of the riding pole is fixed under the insulating pad, and the upper end passes through the aperture on the riding crossbeam and is adjusted and fixed by a nut. The components that make up all the batteries in the present invention are independent, without any parts that need to be welded or glued; the battery pack can be designed to consist of several batteries according to specific needs; the whole set of batteries is easy to disassemble and assemble, and the materials can be reused many times; The structure is simple and the design is reasonable.

Description

technical field [0001] The invention belongs to the field of battery pack assembly, in particular to a battery pack structure in which single cells are connected by pressure. Background technique [0002] Zinc-air batteries have attracted widespread attention because of their large capacity, high specific energy, stable working voltage, environmental protection, and cheap materials. It is convenient, and the mechanical strength of the battery pack is not enough and can only be discharged statically, and the industrial field of application is limited, which is not conducive to the commercialization process of zinc-air battery products. [0003] The structure design of the existing zinc-air battery structure group adopts the method of welding or crimping or directly protruding the tabs and relying on screw tightening to connect the upper and lower single cells. The method of welding the positive and negative electrodes in series between two single cells is labor-intensive, an...

AI Technical Summary

Problems solved by technology

The method of welding the positive and negative electrodes in series between two single cells is labor-intensive, and in general, if one battery leaks during operation, the performance of the entire battery pack will decline. At this time, the faulty single cell should be replaced quickly. In the past, the welding point was cut off and re-welded after replacing the new battery; the battery pack was connected by crimping, the mechanical strength of the side was not enough, and it could only be discharged statically, and the gas diffusion electrode was welded on the metal frame. Once the carbon electrode Can not be used, all battery structural materials can not be used, many materials can only be used once, most battery parts are difficult to recycle, the use cost of zinc-air batteries increases; the disassembly and assembly of screw connections is complicated and time-consuming, And in the bumpy road conditions, the screws will be loosened due to the bumps, resulting in poor contact and the battery pack cannot be discharged normally.
