Document Type and Number:
WIPO Patent Application WO/2018/084425
Kind Code:
A1
Abstract:
The present invention relates to a battery management system, comprising: at least one cell group including first and second battery cells which are connected in parallel between first and second bus bars; a plurality of first and second measurement terminals formed on the first and second bus bars; a plurality of third and fourth measurement terminals which are formed on the first bus bar at positions corresponding to one end of each of the first and second battery cells; a cell voltage measurement unit for measuring a cell voltage of the cell group by using the first and second measurement terminals; a voltage drop measurement unit for measuring an error voltage corresponding to the resistance of the first bus bar by using the third and fourth measurement terminals; and a battery management unit for calculating a cell correction voltage by using the cell voltage and the error voltage.
