HIERARCHICAL THREE-LEVEL CONTROL SYSTEM FOR HIGH-VOLTAGE BATTERY OF ELECTRIC ENERGY ACCUMULATORS Russian patent published in 2014 - IPC H02J7/00 H02J7/10 

FIELD: electricity.

SUBSTANCE: invention relates to the field of electric engineering and it can be used for manufacturing of high-voltage batteries of electric energy accumulators for transportation and power-generating sectors. In the claimed device in accumulator control units at the low level of battery control besides available transformer channel of active selective balancing there's additional second choke channel of nearby balancing that allows intramodular balancing of accumulators charge under control of the control units at the low and medium control level and simultaneous intramodular balancing by means of transformer channel of selective balancing and accumulating line under control of the battery control unit at the upper control level.

EFFECT: speeding-up of process of charge balancing in accumulators, improving their efficiency factor and degree of complexity.
