Acid pumping control technology of container formation lead-acid storage battery

Abstract

The invention discloses an acid pumping control technology of a container formation lead-acid storage battery, comprising the steps of: 1) allowing a storage battery after formation to stand for 1-3 h to make a pole plate and a separating plate to fully absorb acid, 2) charging for 1-3 h with a constant voltage and a limited current to dissolve free acid out, 3) then trickle charging, and 4) pumping away excess free acid by an acid pumping machine under the state of trickle charging after the amount of the dissolved acid liquid is not changed with time. The acid pumping control technology of the container formation lead-acid storage battery effectively balances the voltage stability of each circuit battery, completely eradicates the phenomenon of voltage fluctuation caused by different internal resistance of the battery during constant voltage charging, and also eliminates the battery acid leakage phenomenon.

Description

technical field [0001] The invention relates to an acid pumping control process for internalizing a lead-acid storage battery. Background technique [0002] The internalization of lead-acid batteries is carried out in the form of quantitative rich liquid. At the end of battery charging, the excess free acid should be taken out to prevent the occurrence of battery acid leakage. Since the lead-acid battery is used in the state of poor liquid, once the free acid is excessive, it will cause acid leakage. Therefore, the control of the free acid by various manufacturers is very strict, but with the increase of the number of cycles, the battery will continue to lose water ( The reasons are: ⑴ low sealing reaction efficiency ⑵ microporous volatilization of the plastic case ⑶ self-discharge caused ⑷ long-term floating charge), when the water loss rate is greater than 15%, the battery life is about to end or water maintenance is required. Therefore, the control of the amount of acid ...

Problems solved by technology

Since the lead-acid battery is used in the state of poor liquid, once the free acid is excessive, it will cause acid leakage. Therefore, the control of the free acid by various manufacturers is very strict, but with the increase of the number of cycles, the battery will continue to lose water ( The reasons are: ⑴ low sealing reaction efficiency ⑵ volatilization of micropores in the plastic case ⑶ self-discharge caused ⑷ long-term floating charge), when the water loss rate is greater than 15%, the battery life is about to end or water maintenance is required

Therefore, the control of the amount of acid in the battery has become a dilemma. If the amount of acid is too much, it will leak acid. If the amount of acid is too small, it has caused a series of problems, shortening the cycle life, and there is a hidden danger of thermal runaway.
