Embodiment Construction

[0012] First, place a temporary top cover before the battery is formed. The temporary top cover is consistent with the normal battery top cover. It has the functions of exhausting and slowing down the volatilization of water and acid mist. It maintains the consistency of the battery acid level and density, and at the same time reduces acid adhesion on the battery surface. Eliminate the arc on the battery surface and reduce the risk of battery fire;

[0013] A water bath is used for heat preservation during the battery formation process, and the distance between battery rows should not be less than 30 mm, which not only ensures sufficient water around the battery, but also ensures the circulation of circulating water. By controlling the temperature and flow of circulating water, the internal formation temperature of the battery is controlled during the formation process. If the internal temperature of the battery is high, turn on the circulating water cooling device, increase t...

Abstract

The invention provides a formation method for a maintenance-free lead-acid storage battery, belongs to the technical fields of formation and charging, and solves the problems of relatively high charging time consumption, uncontrollable evaporation of water, relatively thick acid mist, and the like. The formation method for the maintenance-free lead-acid storage battery comprises the steps of battery assembling, electrolyte pouring, electrifying and forming, wherein a temporary top cover is placed on the battery in the formation process; and the temporary top cover is consistent to a normal battery top cover, and has the effects of exhausting air, and slowing down volatilization of moisture and acid mist, keeping consistency of battery acid liquid level and density, reducing acid attachment on the surface of the battery, eliminating electric arc on the surface of the battery, and reducing fire risk of the battery. The formation method has the advantages of reducing water loss and acid mist volatilization in the formation process so as to ensure consistency of battery acid liquid level and acid specific gravity, ensuring temperature stability in the formation process of the battery, and lowering charging time in formation.

Description

technical field [0001] The invention belongs to the technical field of formation charging, and relates to a formation method of a maintenance-free lead-acid storage battery. Background technique [0002] The commonly used formation charging methods for lead-acid batteries include constant current charging and constant voltage charging. However, there are the following problems in the existing technology: 1. Most of the charging time is long, and most of the charging time takes more than ten to twenty hours; 2. The evaporation of water during the charging process is uncontrollable. The consistency of acid liquid level and acid specific gravity between cells of the same battery is poor; 3. The acid mist in the formation process is relatively large, and it is easy to form a small arc on the battery when it adheres to the surface of the battery, which may cause the battery to catch fire. Contents of the invention [0003] The object of the present invention is to propose a ma...
