FIELD: electrical engineering.
SUBSTANCE: invention relates to the field of electrical engineering and can be used in chargers of lithium-ion batteries. Technical result is achieved in a method for controlling the charging and consumption of a battery charge, in which, in the charging mode, a power source is connected to the battery cells, current supply is adjusted depending on the state of the battery cells, wherein the energy transfer to the cells is carried out in a resonant transfer mode, in which the direct current of the voltage source is first converted into an alternating current having a law of change in the form of a sinusoid, and then converting the alternating current into the direct current of the cell supply, by adjusting the value of the average value of the cell supply current by switching the supply circuit of the cell at the moment when the instantaneous value of the alternating current has a zero value, regulation of the average value of the cell current is carried out with a high frequency of current change, in the charge consumption mode, the residual capacitance of the cell is monitored by the internal resistance of the cell, and if the value of the cell residual capacity is below the specified limit, then for compensation the energy is pumped from other cells.
EFFECT: minimization of battery aging during charging and discharging with provision of increase of possible number of charge-discharge cycles of the battery operated by the disclosed method as compared to the battery operated by analogue methods.
