Abstract
The present disclosure relates to battery cell balancing using duty ratio control, and more particularly, to a battery cell balancing method and system with improved accuracy and efficiency by detecting a temperature of a resistance caused by a current flowing in a battery cell during battery cell balancing, calculating a duty ratio of the battery cell balancing according thereto, and detecting a voltage of the battery cell when a predetermined time elapses after the cell balancing operation.
