METHOD FOR SELF-DISCHARGE COMPENSATION OF LEAD STARTER STORAGE BATTERY Russian patent published in 2020 - IPC H01M10/42 H01J7/00 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical equipment, namely to the method of self-discharge compensation of lead starter accumulator batteries. In the proposed method, the discharge value and self-discharge rate of the accumulator battery are evaluated, the maximum charging current is determined I_charg.max = P/(2.6 n), where P is the limited power of the power source, n is the number of accumulators in the battery, the minimum current transmission time I_charg.max is determined, wherein to compensate for the lost charge t_min = ΔQ_lost/I_charg, where ΔQ_lost is value of lost battery charge at self-discharge, current is passed from power source with power P during time not less than 2 t_min., then periodically through time t = ΔQ_lost/(dQ/dt), where dQ/dt is the rate of self-discharge, passing reverse current or charging current through the storage battery from the source with limited power for at least t = 5.2 n ΔQ_lost/P. Compensation of self-discharge in accordance with the proposed method is possible using autonomous mobile energy sources in time intervals of daily periodicity of action from allowable values of self-discharge to maintain a level close to complete availability. Application of standard solar batteries as photocells with dimensions of 20×30×1 cm³ enables to obtain voltage of 12 V and provides power of more than 10 W.

EFFECT: higher reliability of lead storage batteries operation is technical result of invention.
