Problems solved by technology

[0003] At present, there are many problems in the process of internal formation of lead-acid batteries, mainly including the following problems: the battery formation process takes too long, which delays the production efficiency of the battery; The conversion of substances, excess electricity will lead to a large amount of outgassing in the battery and the temperature rise in the final stage of battery formation. The erosion of bubbles and high temperature will damage the structure of active materials and affect battery performance.

Abstract

The invention relates to an internalization charging method for a power type lead-acid battery, belonging to the technical field of power type lead-acid battery charging. The internalization charging method described in the present invention performs segmental processing according to the principle of the formation process, adopts different internalization charging methods for different charging stages, and solves the problem of long time in the existing internalization charging process and the conversion efficiency of battery charging power Low, low battery production efficiency and other issues. The charging method of the present invention significantly reduces the production cycle, shortens the formation time of the battery, achieves the best formation performance of the pole plate, and obtains the effect of rapid formation; by adopting an appropriate formation system, the formation performance of the pole plate is optimal; by adopting a suitable The formation temperature accelerates the conversion of active materials inside the battery, thereby shortening the formation time.

Description

technical field [0001] The invention relates to an internalization charging method for a power type lead-acid battery, belonging to the technical field of power type lead-acid battery charging. Background technique [0002] At present, the charging method of internal formation has been promoted and used in the domestic market. Compared with the traditional charging method, internal formation of acid cycle can effectively save battery formation time and production efficiency. With the continuous improvement of market demand and charging requirements, how to reduce the production cycle, shorten the battery formation time, and improve the battery formation effect has become the main problem to be solved by internal formation batteries at this stage. [0003] At present, there are many problems in the process of internal formation of lead-acid batteries, mainly including the following problems: the battery formation process takes too long, which delays the production efficiency ...
