ELECTRIC POWER ACCUMULATION SYSTEM INTENDED FOR USE AS UNINTERRUPTED POWER SUPPLY SOURCE, AND METHOD FOR CONTROLLING SAID SYSTEM UNDER CONDITIONS OF STABLE OPERATION OF PIEZOELECTRIC GENERATORS Russian patent published in 2025 - IPC H02J7/32 H02N2/18 B63J99/00 

FIELD: electricity.

SUBSTANCE: invention relates to a system for accumulating electric energy obtained from piezoelectric transducers. System comprises at least two piezoelectric transducers and at least two electric energy accumulators connected to piezoelectric transducers by electrical communication. Piezoelectric converters are assembled into a package and connected in parallel to each other, electric energy accumulators are connected in parallel to each other. Package of piezoelectric transducers is placed under the base of the lifting device performing the same type of work. Besides, the system comprises a switching unit for connection of accumulators to piezoelectric transducers, disconnection of accumulators from piezoelectric transducers, connection of accumulators to consumers and disconnection of accumulators from consumers. System also has a controller for generating signals which control charging and discharging of a separate accumulator depending on the level of its charge. Between piezoelectric transducers and accumulators there is a switch for disconnection of piezoelectric transducers from accumulators when it is necessary to replace or repair components of the system. There are versions of the system design, which relate to the number and arrangement of packages under the base of the lifting device, the number of piezoelectric transducers in the packages, as well as dividing the accumulators into groups for their connection to one consumer or different consumers.

EFFECT: possibility of system operation as uninterrupted source of electric energy received from piezoelectric converters.
