ACTIVE BATTERY CELL BALANCING SYSTEM Russian patent published in 2023 - IPC H02J7/02 H01M10/42 

FIELD: electrical engineering.

SUBSTANCE: systems for active balancing of battery cells. The system contains individual modules for measuring cell state parameters, electrically interconnected through the secondary windings of induction power converters, individual power exchange modules, each of which is made in the form of an inverter on a planar transformer with control keys and a block for generating and issuing control signals in the form of a low-voltage differential bus. At the same time, the system is equipped with inverter control key drivers communicated with the differential bus, and individual modules for measuring cell parameters and individual power exchange modules are connected in parallel to the bus through galvanic isolation.

EFFECT: reduction of the mutual influence of the magnetic fields of transformers with the elimination or significant reduction in the probability of occurrence and magnitude of induced EMF in planar coils.
