Description

Technical Field

[0001] This utility model relates to the field of lead-acid battery technology, and in particular to a direct-connection impregnation encapsulation structure for stacked automotive lead-acid batteries. Background Technology

[0002] Lead-acid batteries are chemical power sources that use lead and its oxides as electrode materials and sulfuric acid solution as electrolyte. They belong to the category of secondary batteries (rechargeable batteries). The core of lead-acid batteries is to store and release electrical energy through the reversible chemical reaction between the electrodes and the electrolyte during charging and discharging. Its essence is a cycle of "redox reaction". When the battery is connected to an external load (such as a car starter motor or an electric vehicle motor), redox reactions occur at the positive and negative electrodes, converting chemical energy into electrical energy. It is one of the earliest commercialized and most widely used batteries in the world. With its low cost, high reliability, and good high-current discharge performance, it still occupies an important position in many fields. However, at present, the busbars between the cells of stacked lead-acid batteries used in vehicles are connected by bridges, which are prone to breakage during use. Moreover, during the impregnation and encapsulation process, the bridge connection is in direct contact with acid and is easily corroded. Utility Model Content

[0003] The main objective of this invention is to provide a stacked automotive lead-acid battery direct-connection impregnation encapsulation structure, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A stacked vehicle lead-acid battery direct-connect impregnation encapsulation structure includes a battery case and a battery cover. The battery case has adjacent individual cell slots inside, and each individual cell slot has a group of electrodes. The electrode groups have positive and negative tabs near their front and rear ends. A busbar is provided at the upper end of the positive and negative tabs. An extension end is connected to the front end of the busbar, and a terminal post is connected to the front end of the extension end.

[0005] More preferably, the adjacent body grooves are connected by a busbar, and the lower end of the shell cover is provided with an impregnation and sealing groove.

[0006] More preferably, the impregnation tank corresponds to the busbar inside the battery casing.

[0007] Further preferred options are those where the busbar is made of multi-element alloy materials such as lead, tin, sodium, and rare earth.

[0008] Compared with the prior art, the present invention has the following beneficial effects: In this invention, by setting a busbar and an impregnation tank, the connection between the body tanks can be changed from a bridge connection to a direct busbar connection, which increases the connection strength, avoids easy breakage during use, saves materials, eliminates the need for additional bridge connection parts, and also allows the busbar to be completely buried in the glue inside the impregnation tank during the impregnation and encapsulation process, preventing the busbar from being corroded by acid.

[0011] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0012] Participation Figure 1-2 As shown, a stacked vehicle lead-acid battery direct-connect impregnation encapsulation structure includes a battery compartment 1 and a battery cover 2. The battery compartment 1 has adjacent individual cell compartments 3 inside, and the individual cell compartments 3 have electrode groups 4 inside. The electrode groups 4 have positive and negative tabs 5 near the front and rear ends. The positive and negative tabs 5 have a busbar 6 at the upper end. The front end of the busbar 6 is connected to an extension end 701, and the front end of the extension end 701 is connected to a terminal post 7.

[0013] Adjacent body slots 3 are connected by busbars 6. The lower end of the battery cover 2 is provided with an impregnation groove 601, which corresponds to the busbars 6 inside the battery slot 1. The busbars 6 are made of multi-element alloy materials such as lead, tin, sodium, and rare earth, which can change the connection between body slots 3 from a bridge connection to a direct connection of busbars 6, increasing the connection strength, avoiding easy breakage during use, saving materials, and eliminating the need for additional bridge connection parts. In addition, during the impregnation process, the busbars 6 can be completely buried in the glue inside the impregnation groove 601, preventing the busbars 6 from being corroded by acid.

[0014] It should be noted that this utility model is a direct-connection impregnation encapsulation structure for stacked vehicle lead-acid batteries. It can change the connection between the body grooves 3 from a bridge connection to a direct connection of the busbar 6, which increases the connection strength, avoids easy breakage during use, saves materials, and does not require an additional bridge connection. In addition, during the impregnation encapsulation process, the busbar 6 can be completely buried in the glue inside the impregnation tank 601, which prevents the busbar 6 from being corroded by acid.
