METHOD OF CHARGING LEAD-ACID BATTERY Russian patent published in 2024 - IPC H01M10/44 H01M10/06 H02J7/00 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, namely to a method of charging lead-acid batteries of vehicles with direct current, and can be used to reduce the time of their readiness for operation after a long-term storage process. Reduction of lead-acid storage battery charging time is achieved by passing through a lead-acid accumulator current of charge of constant value, with registration of density and temperature of electrolyte, voltage between poles of battery, intensity of gas release, wherein charging process is carried out with hydromechanical mixing of electrolyte solution while charging process is terminated after one hour of excessive gas release.

EFFECT: use of hydromechanical mixing in combination with accumulator charging by passing electric current in reverse direction allows to reduce lead-acid accumulator battery charging time by more than 2 times.
