METHOD FOR LEAD-ACID BATTERY FORMATION BY PULSE ASYMMETRIC CURRENT Russian patent published in 2014 - IPC H01M10/44 

FIELD: electricity.

SUBSTANCE: invention is related to the field of electric engineering, in particular to manufacturing technology of lead-acid accumulators and batteries as well as their maintenance during operation. The invention target is to increase efficiency of lead-acid batteries formation in process of their manufacturing. The technical result is attained by the reason that during formation of a lead-acid battery by pulse asymmetric current through the converter from AC mains according to the method based on interchange of charge and discharge current pulses with repetition frequency f/n (f is the frequency of AC mains, n is the division factor (n=1, 2) and duration of discharge current pulses d_disch=(n/f)-d_char, where d_char is duration of charge current pulses, at that duration of charge current pulses is selected within the limits of 0.25 Tm ≤ d_char < 0.5 Tm, where Tm is an oscillation period in AC mains and current value in discharge current pulses I_disch in the formation process is changed depending on charge accumulation in the battery smoothly or stepwise within the limits of 0 ≤ I_disch < 0.01 C_r, where C_r is a numerical value of the rated capacity of the formed battery.

EFFECT: reducing time for battery formation, reducing electrolyte temperature during formation, improving efficiency of current usage.
