ACCUMULATOR SELF-DISCHARGE COMPENSATION DEVICE Russian patent published in 2019 - IPC H02J7/35 H02H7/18 

FIELD: electrical engineering.

SUBSTANCE: invention can be used in devices for charging accumulator batteries stored, in order to compensate for their self-discharge. Technical result is achieved due to that in device for compensation of self-discharge of accumulator batteries there additionally introduced is second photocell, key transistor, control transistor, stabilitron, relay and resistor; wherein relay winding and collector circuit of key transistor are connected in series and connected between positive and negative buses of device, and key transistor base is connected between mid point of series-connected resistor and control transistor, stabilitron is connected between the base of the control transistor and the photocell connected to the negative bus, and relay contacts are connected to outputs of photocells.

EFFECT: technical result is aimed at expansion of range of illumination of device and its applicability.
