Abstract

The invention discloses a lead-acid battery capacity restorer, which comprises an integrated chip IC1, a field effect transistor T1, comparators IC2A, IC2B, IC2C, IC2D, a connection terminal K1 and a parallel access terminal IC2 of the lead-acid battery capacity restorer , connect the lead-acid battery that needs to restore capacity to terminal K1, charge the lead-acid battery with pulse current, and discharge the lead-acid battery during the pulse interval. The invention can effectively stabilize the capacity of the lead-acid battery, suppress the vulcanization reaction, keep the battery with high-efficiency power storage function, and automatically desulfurize the vulcanized battery to form a good charge-discharge cycle inside. Return capacity to original nominal value.

Description

technical field [0001] The invention relates to a capacity recovery device for a lead-acid storage battery. Background technique [0002] Lead-acid battery is a battery whose electrodes are mainly made of lead and its oxides, and the electrolyte is sulfuric acid solution. It is used more and more widely as a backup power supply or main power supply on electrical equipment. However, lead-acid batteries will naturally age during normal use, forming a layer of thick and hard lead sulfate recrystallization on the plate. The lead sulfate formed during the discharge process of the battery is originally fine particles, called disposable. Crystals, once charged, can disappear. If the battery is in a half-discharge state for a long time, the lead sulfate on the plate will dissolve into the electrolyte when the temperature rises, and when the temperature drops, it will crystallize and attach to the plate again, and the junction will become larger and thicker. This recrystallized b...
