JPS61264664A - Electrolyte pouring method of lead-acid battery - Google Patents

Abstract

PURPOSE:To make the electrolyte amount of each cell uniform by forming a vent in each partition of container in alignment, pouring electrolyte with the container slanting, then returning the container in the vertical position after completion of electrolyte pouring. CONSTITUTION:When electrolyte is poured in each cell 3, a container 1 is slanted so as to position a vent 5 upward, then electrolyte is poured in one cell 3. Then the electrolyte is poured to a specified amount, the upper height of the electrolyte exceeds the position of the vent, and each cell 3 is connected through each vent and the electrolyte amount of each cell is made uniform. The container 1 is returned in the vertical position. By pouring the electrolyte to only one cell, the electrolyte amount in each cell is made uniform and the pouring of electrolyte is simplified.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a lead acid battery injection method.

BACKGROUND ART Conventionally, when injecting an electrolyte into a battery case body, the electrolyte was poured into each cell separated by a partition within the battery case body.

The problem that the invention aims to solve For this reason, it was difficult to maintain a constant amount of liquid injected into each cell.

The present invention aims to solve the above-mentioned conventional drawbacks and provide a method of pouring liquid that is easy to pour and also allows the amount of electrolyte in each cell to be constant.

Means for Solving the Problems In order to achieve the above object, the liquid injection method of the present invention is such that the ventilation holes provided in each partition part that partitions the inside of the battery case body are formed in a straight line. The purpose is to inject liquid at an angle and return the main body of the container to its original position after injecting liquid.

Effect: According to the above method, since the surface of the electrolyte is higher than the position of the ventilation hole during injection, each cell communicates through the ventilation hole, so the amount of electrolyte in each cell becomes constant, and after that, When the main body of the battery case is returned to its original position, the height of the surface of the electrolyte becomes lower than the position of the ventilation hole, and the electrolyte of each cell does not communicate with each other.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

In the figure, 1 is a battery case body, and the inside of this battery case body 1 is partitioned into a plurality of cells 3 by partitions 2. Reference numeral 4 denotes a group of electrode plates arranged within each cell 3. Reference numeral 5 denotes a ventilation hole formed in each partition 2, and the ventilation holes 5 of each partition 2 are formed in a straight line. 6 is a lid body.

In the above configuration, when injecting electrolyte into each cell 3,
The container main body 1 is tilted to the right in FIG. 1 and poured into one cell 3. When a predetermined amount of electrolyte is injected, the surface height of the electrolyte becomes higher than the position of the ventilation hole 5, and each cell 3 communicates through the ventilation hole 5, so the amount of electrolyte in each cell 3 decreases. becomes constant. After this, when the electrolysis body 1 is returned to its original state, the surface height of the electrolyte becomes lower than the position of the ventilation holes 6, and the electrolyte does not move between the cells 3.

Effects of the Invention As described above, according to the present invention, the amount of electrolyte in each cell becomes constant by simply injecting the electrolyte into one cell, and the electrolyte can be easily injected.
