Title:
METHOD AND SYSTEM FOR EFFECTIVE BATTERY CELL BALANCING THROUGH DUTY CONTROL
Document Type and Number:
WIPO Patent Application WO/2018/074807
Kind Code:
A1
Abstract:
The present invention relates to battery cell balancing using duty ratio control and, more specifically, to a method and system for battery cell balancing having improved accuracy and efficiency by detecting the temperature of a resistor generated by a current flowing through a cell during battery cell balancing, calculating the duty ratio of cell balancing based on same, and detecting the voltage of the battery cell after a predetermined time following the cell balancing operation.
