Starting valve control type lead acid storage battery with pure water chambers

Abstract

The invention provides a starting valve control type lead acid storage battery with pure water chambers, which mainly comprises a battery jar and a battery cover, wherein the battery jar is divided into twelve unit cells by middle walls; the battery cover is matched with the battery jar; the unit cells are arranged in two lines; one line of the unit cells are plate group chambers, plate groups are placed in the plate group chambers, and electrolyte is poured into the plate group chambers; the other line of the unit cells are the pure water chambers, and pure water or the electrolyte is poured into the pure water chamber; and each plate group corresponds to one pure water chamber, and a communicating guide tube and a communicating pore are arranged between the plate group and the corresponding pure water chamber. The plate groups are compactly assembled with a plurality of pieces, a positive plate grid is made of lead antimony alloy, a negative plate grid is made of lead calcium alloy, the mesh density of the positive plate grid and the negative plate grid is high, and the lead acid storage battery is provided with the pure water chambers, the communicating guide tubes and the communicating pores to ensure that an absorbent glass mat (AGM) separator is automatically adjusted into an under-saturated optimum state, and even working under a 50 DEG C high temperature environment, the storage battery not only has a long cycle service life but also has minimal water loss, is not lack of water during years of service life, and achieves to be real maintenance-free.

Description

technical field [0001] The invention relates to a lead-acid storage battery for starting, which is mainly used in the fields of automobiles, tractors, construction machinery, etc., and specifically refers to a valve-controlled lead-acid storage battery for starting with a pure water chamber. Background technique [0002] The structure of lead-acid storage battery mainly contains positive (negative) pole plate, dividing plate, electrolyte, battery tank, connecting bar and positive and negative terminal etc. to form, and positive (negative) pole plate is that grid among the present invention is coated with lead paste constitute. A lead-acid battery is a device that converts chemical energy into electrical energy and belongs to the DC power supply. [0003] At present, the manufacturing process of valve-regulated lead-acid batteries (abbreviated as VRLA) with ABS plastic battery tank covers is roughly as follows: [0004] Alloy Configuration→Grid Manufacturing→Mechanical Coat...

AI Technical Summary

Problems solved by technology

However, it is generally not allowed to add electrolyte to valve-regulated lead-acid batteries. That is to say, battery repair is actually an illegal operation, which has the following defects: Potential risks; Second, regular maintenance will cause certain economic losses to users and bring unnecessary troubles

[0008] Especially for the car battery used for starting, especially the taxi battery installed next to the engine, the working environment temperature is relatively high, which can reach about 50°C. In addition, the taxi runs for a long time, 20 hours out of 24 hours. , this type of battery has greater water loss and worse maintenance-free performance

[0009] In addition, the battery tanks and battery covers of valve-regulated lead-acid batteries currently on the market are all made of ABS plastic materials. ABS has poor thermal meltability), high surface hardness, good rigidity, high internal gas pressure, but poor impact resistance, and has the following defects: First, the material has a large specificity, high unit price, and the use of epoxy resin glue, resulting in The battery cost is relatively large; secondly, if figure 1 As shown, since the intermediate wall between each cell is brittle due to ABS, it cannot be perforated, so the connection between adjacent cells must be bridge welding. The structure of bridge welding is as follows image 3 As shown, it is mainly welded by oxygen, which must be done manually, which wastes a lot of labor costs and low production efficiency; thirdly, the seal between the battery tank and the battery cover is made of epoxy resin, The operation steps are complicated. Firstly, the battery tank and the battery cover must be bonded, followed by terminal glue to seal the terminals, and finally, marking glue to mark the positive and negative polarities. Between the three glues, heat and cure for a period of time respectively. Complicated operating steps again reduce production efficiency and increase production costs
