BATTERY CELL BALANCING SYSTEM AND METHOD USING LC RESONANCE

摘要

The present invention relates to a battery cell balancing system and method using LC resonance. The present invention comprises: a drive unit including one or more battery cells connected in series, a resonance module for performing a resonant operation, and a switch unit provided so as to allow electric charges stored in the resonance module to be transferred to each of the one or more battery cells; and a control unit for measuring a resonance period of the resonance module according to a voltage state of each of the one or more battery cells, and transferring the electric charges charged in the resonance module to each of the one or more battery cells by controlling an on/off operation of the switch unit according to the measured resonance period.
