CHARGE CONTROL CIRCUIT, DEVICE OPERATING FROM BATTERY, CHARGING DEVICE AND METHOD OF CHARGING Russian patent published in 2013 - IPC H02J7/00 

FIELD: electricity.

SUBSTANCE: charge control circuit (30), which controls a charging unit (3), which charges a lead accumulator battery (10), used as a source of power supply for a device (1), comprises the first receipt unit (36), which receives, by the command of charge start, the total quantity of electricity of lead accumulator battery discharge within the time from the moment of completion of the previous charge to the start of the next charge. The total quantity of discharge electricity is divided into the first quantity of discharge electricity, which is the quantity of discharge electricity of the discharge current, the current value of which is less than the pre-selected level, and the second quantity of discharge electricity is not below the pre-selected level, a calculation unit (37), which provides for production of the first and second quantity of charge electricity, corresponding to the first and second quantity of discharge electricity, produced by the first unit of receipt and the discharge electricity quantity, required for charging of the lead accumulator battery as the sum of the received first and second quantity of charge electricity, and a charge control unit (34), which controls the charging unit on the basis of the charge electricity quantity.

EFFECT: longer service life of accumulator batteries.
