Problems solved by technology

[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

Embodiment 1

[0032] Perform electrode plate production and curing according to the normal production process of the battery; select a small positive grid, place the miniature temperature probe in the center of the grid and fix it; manually apply paste on the grid to obtain a wet plate; wet the plate with acid , Pass the pressure roller, solidify and dry; Wrap 5 conventional plates and 1 plate with temperature probe together to form 6 groups, the plate with temperature probe is located in the middle of the 6 groups; Enter the tank, cover, and add acid; all the processes of the grid must meet the process requirements of the conventional grid; turn on the wireless signal receiver to monitor the temperature change from the acid addition to the battery shelf formation until the battery is removed from the shelf. Curve see figure 1 , The battery performance data of the prepared battery is shown in Table 1.

[0033] Among them, the miniature temperature probe is 10mm long, 5mm wide, and 2mm thick. ...

Embodiment 2

[0039] Perform electrode plate production and curing according to the normal production process of the battery; select a small positive grid, place the miniature temperature probe in the center of the grid and fix it; manually apply paste on the grid to obtain a wet plate; wet the plate with acid , Pass the pressure roller, solidify and dry; Wrap 4 conventional plates and 2 plates with temperature probes together to obtain 6 groups, one plate with temperature probe is located in the middle of the 6 groups, and one is located The outermost of the 6 pole groups; insert the pole groups into the groove, cover, and add acid; all the grid processes need to meet the process requirements of the conventional grid; turn on the wireless signal receiver, you can monitor the battery from adding acid to the battery rack Formation, until the internal temperature change of the battery is off the shelf.

[0040] The miniature temperature probe is 10mm long, 5mm wide, and 2mm thick. It has acid an...

Embodiment 3

[0042] Except that the miniature temperature probe does not have a thin hook, the other measurement methods are completely the same as in the second embodiment.

Abstract

The invention relates to a method for measuring production process parameters of batteries, and discloses a temperature test method inside a pole group during a container formation period of a lead-acid battery. The method comprises the following steps: 1) producing and curing a pole plate according to the normal production process of the battery; 2) selecting a small positive grid, placing and fixing a miniature temperature probe in the center of the grid; 3) hand-coating a paste on the grid to obtain a wet plate; 4) processing the wet plate with an acid liquid and rolling, and curing and drying; 5) packaging a conventional pole plate and a pole plate with a temperature probe together to obtain a pole group; 6) putting the pole group into a tank, covering by a cover, and adding the acid liquid; 7) turning on a wireless signal receiver to monitor the inside temperature change from acid addition, battery container formation on a rack to battery unloadingobtaining. The temperature measuring method is simple in process, avoids damage to the battery and the pole plate, saves labor and effort, improves operation 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 a pole group during the internalization of a lead-acid battery. Background technique [0002] The internal formation process is also known as the "cadmium-free internal formation process", which is to directly assemble the battery after curing and drying the battery pole plate into a battery, and carry out the formation and charging of the battery to obtain the finished product. The internal chemical conversion process eliminates the traditional cadmium-containing external chemical conversion processing and production methods, including plate tank formation, plate washing, secondary drying, and battery supplementary charging, which involve energy consumption and main wastewater generation processes. The cadmium-free internal chemical conversion process and Compared with traditional external chemical conversion...
