Problems solved by technology
The weight loss in the formation process of lead-acid batteries is one of the important parameters to measure the formation efficiency. For the same type of battery, it is generally believed that less water loss leads to high formation efficiency, and more water loss leads to low formation efficiency.

The invention provides a method for determining the weight loss and volatilization weight loss of electrolyzed water in the formation process of lead-acid batteries. The method is carried out through an acid adding pot, which is installed on the battery, and a first absorption column is arranged above the acid adding pot. The first absorption column is filled with anhydrous copper sulfate, the first absorption column is connected with the acid adding pot through a first ceramic filter tube, the second absorption column is installed above the first absorption column, and the second absorption column is filled with There is anhydrous copper sulfate, the second absorption column is connected with the first absorption column through a second ceramic filter tube, the first ceramic filter tube and the second ceramic filter tube are arranged alternately at intervals, and there is a tailpiece above the second absorption column Air pipe, weighing the total weight M1 of the battery and the acid adding pot before the formation and the total weight M4 after the formation, weighing the total weight M2 of the first absorption column and the filler before the formation and the total weight M3 after the formation, and then passing formula to calculate. The method is simple in operation, easy to implement and high in precision.
Description
technical field [0001] The invention relates to the field of battery formation detection, in particular to a method for determining the weight loss and volatilization weight loss of electrolyzed water during the formation process of lead-acid batteries. Background technique [0002] The weight of lead-acid batteries has certain changes before and after formation. Generally, lead-acid batteries will lose weight to varying degrees after formation. The weight loss in the formation process of lead-acid batteries is one of the important parameters to measure the formation efficiency. For the same type of battery, it is generally believed that the formation efficiency is high with less water loss, and the formation efficiency is low with more water loss. Formation weight loss is mainly divided into two parts, one part is the weight loss caused by the gas produced by electrolysis of water, and the other is the weight loss caused by the volatilization of the electrolyte. Determinin...
