Title:
CELL BALANCE CONTROL DEVICE AND CELL BALANCE CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2019/093154
Kind Code:
A1
Abstract:
This cell balance control device comprises cell balance controllers (501 to 50n) including control units (511 to 51n) which: determine an average value of the charge states of all of a plurality of battery cells (111 to 11n); determine a linear approximate equation with respect to the variation of the charge states of the plurality of battery cells (111 to 11n); and, with respect to a battery cell (111 to 11n) of which the charge state is greater than the average value, controls the driving of wireless electric power transmission units (301 to 30n) so that power is transmitted from the battery cell (111 to 11n) to a battery cell (111 to 11n) which is adjacent on the downward slope side of the linear approximate equation.
