METHOD FOR LEAD-ACID BATTERY CONTROL AND POWER SOURCE SYSTEM Russian patent published in 2012 - IPC H02J7/10 

FIELD: electricity.

SUBSTANCE: lead-acid battery control method is distinguished by the fact that the first area is established (stretching until the accumulated discharged capacity D₁ is achieved whereat theoretical discharged capacity has the maximum value D_max) and the subsequent second area wherein accumulated discharged capacity D₁ is established, and by the fact that R₁ value obtained by way of division of accumulated discharged capacity C₁ by accumulated discharged capacity D₁ in the first area is such that R₁ value is more than R₂ value obtained by way of division of accumulated discharged capacity C₂ by accumulated discharged capacity D₂ in the second area.

EFFECT: elimination of the capacity reduction problem caused by insufficient charge and deterioration related to excessive charge of the lead-acid battery as a result of random charge.
