FIELD: electricity.
SUBSTANCE: invention relates to devices for quick charge of batteries. The control unit calculates, on the basis of change of the expected amount of the energy generated by the energy generation unit, change of the expected amount of the energy supplied by the power supply unit, and the present amount of the electric energy saved by the battery, change of the expected amount of the electric energy saved by the battery in case when electric energy is still supplied from the mains to the battery. The control unit sets a time span of energy decrease which is a time span within which the electric energy is not supplied from the mains to the battery when in the change of the expected amount of the accumulated electric energy of the battery the first moment is detected which is a moment in which the expected amount of the accumulated electric energy begins to exceed the first reference capacity, and as the first moment it sets the finite time of the time span of energy decrease.
EFFECT: providing of quick total charge.
