DEVICE TO COMPENSATE SELF-DISCHARGE OF ACCUMULATOR BATTERIES Russian patent published in 2015 - IPC H02J7/00 

FIELD: electricity.

SUBSTANCE: invention is referred to electric engineering and may be used for boost charge of stored accumulator batteries in order to compensate their self-discharge. Technical result is attained by the fact that in the device used to compensate self-discharge of accumulator batteries there are additional in-series choke and diode interconnected between positive lead of a photocell and anode of diode protecting from accumulator battery inverting; storage element coupled between anode of the protective diode and negative busbar of the device; switching transistor coupled between the middle connection point of choke and diode and negative busbar of the device; threshold device and setting pulse generator, which outputs are connected to the base of switching transistor while input of threshold device is connected to output of storage element.

EFFECT: oriented towards simplification of the device scheme and expansion of its usability.
