SMART ACCUMULATOR BATTERY CHARGING WITH DIRECT CURRENT Russian patent published in 2020 - IPC H02J7/04 H02J7/00 H02J7/14 H01M10/42 

FIELD: electrical equipment.

SUBSTANCE: invention relates to a method for DC charging of an intelligent battery pack. Intelligent battery pack is connected to charging column and comprises at least two battery modules, each of these battery modules comprising at least two semiconductor power switches and at least one energy accumulator, in which battery unit is connected for charging by means of connection circuit and state of each separate energy accumulator is controlled, wherein according to continuous evaluation of states of corresponding energy accumulators corresponding serial and/or parallel mutual connection of the respective battery modules to each other inside the battery pack is generated dynamically by actuation of semiconductor power switches.

EFFECT: technical result is providing free connection of batteries to each other depending on conditions of voltage level of charging column or state of charge of individual battery cells.
