A method for measuring the temperature inside the pole group during the internal formation of lead-acid batteries

Abstract

The invention relates to a method for measuring parameters of a battery production process, and discloses a method for testing the temperature inside an electrode group during the internal formation of a lead-acid battery. The method includes the following steps: 1) producing and curing the pole plate according to the normal production process of the battery; 2. ) Select a small piece of positive electrode grid, place the miniature temperature probe at the center of the grid and fix it; 3) Manually apply paste on the grid to obtain a wet plate; 4) The wet plate is soaked in acid, passed through a pressure roller, and cured and dried; 5) Wrap the conventional polar plate and the polar plate with the temperature probe together to form an electrode group; 6) Put the electrode group into the tank, cover it, and add acid; 7) Turn on the wireless signal receiver to monitor the process from acid addition to battery Put it on the shelf for formation, until the internal temperature changes of the battery after it is taken off the shelf. The temperature measurement method has a simple process, avoids damage to batteries and polar plates, is quick and labor-saving, and improves operating efficiency. The obtained temperature data is not affected by the external environment and manual operation, and the data consistency is higher.

Description

technical field [0001] The invention relates to a method for measuring battery production process parameters, in particular to a method for measuring the temperature inside an electrode group during the internal formation of a lead-acid battery. Background technique [0002] The internal formation process is also called "cadmium-free internal formation process". It is to assemble the batteries directly after cutting the cured and dried battery plates, and carry out the formation and charging in the batteries to obtain the finished product. The internal formation process cancels the four processes of plate tank formation, plate washing, secondary drying, and battery supplementary charging in the traditional cadmium-containing external formation process, which involve energy consumption and main waste water generation processes. The cadmium-free internal formation process and Compared with traditional externalization, water consumption is reduced by 90%, electricity is saved b...

[0004] The Chinese patent with the application number 201710960704.7 discloses a test method for the internal formation temperature of lead-acid batteries. The temperature is monitored by drilling a temperature measuring hole in the dry electrode group of the battery and inserting a temperature probe. However, this method will destroy the battery structure, and the measured The temperature is the temperature at the edge of the pole group. Since the temperature at different positions of the pole group is not consistent, the temperature measured by this method is low
