的とする。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for inspecting the presence or absence of abnormalities inside a storage battery, and in particular to a method for inspecting the quality of storage batteries that are not equipped with a gas consumption mechanism by detecting minute short circuits between negative and anode plates. The purpose is to provide stable storage batteries.

正常な蓄電池に比べて短寿命となるので、品質の
点で問題がある。 Conventional methods for inspecting the presence or absence of an abnormality inside a storage battery include a method of measuring the open circuit voltage between both pole terminals of the storage battery after charging is completed, or a method of measuring the specific gravity of the electrolyte. However, all of the above methods have the disadvantage that minute short circuits between electrode plates cannot be detected. A storage battery with a minute short circuit is not so defective that it cannot be put to practical use, but
This poses a quality problem as it has a shorter lifespan than a normal storage battery.
本発明は、従来の上記検査法の欠点を解消し、
微細短絡の検出を可能とするものである。 The present invention eliminates the drawbacks of the above conventional testing methods,
This makes it possible to detect minute short circuits.

からであると考えられる。 Generally, when a storage battery finishes charging, in a normal cell, virtually 100% of the charging current is consumed for water electrolysis, so a storage battery without a gas consumption mechanism will generate a large amount of gas; There is a phenomenon that the amount of gas generated is lower in cells that are damaged than in normal cells. The reason for this is that the micro-short circuit part of a cell with a micro-short circuit is always in a discharge state, and 100% of the charging current is no longer consumed for water electrolysis to charge this part, and as a result, the cell becomes normal. This is thought to be due to the fact that the amount of gas generated is smaller compared to the above.

短絡の有無を簡単に判別することができる。 The present invention aims to detect minute short circuits by focusing on this point, and at the end of charging, as shown in the figure, a meter 1 such as a gas pressure gauge or a gas flow meter is connected to each cell of a storage battery 2 that is not equipped with a gas consumption mechanism. By applying the gas to the liquid port 3 provided in each cell and measuring the pressure or amount of gas generated within each cell, it is possible to easily determine the presence or absence of an abnormality, that is, the presence or absence of a minute short circuit.

る。 In addition, an attachment 4 having elasticity such as rubber is attached to the lower part of the meter 1 that comes into contact with the liquid port 3, as shown in the figure of the embodiment, and the display section 5 of the meter 1 shows the pass/fail status in advance based on the data. If an identification display is provided, the measurement operation becomes very simple. Furthermore, it is also possible to install the meter 1 above a conveyor (not shown) so that it can be automatically moved up and down, and those that are found to be defective as a result of measurement are removed from the conveyor.

Since it is possible to easily detect the presence or absence of , it is extremely useful as one of the inspection methods for obtaining storage batteries of good quality, and its industrial value is great.
