CIRCUIT FOR BALANCE-CHARGING SERIAL STORAGE CELLS AND METHOD FOR BALANCE-CHARGING SERIAL STORAGE CELLS

摘要

and a coil for charging the electric charge to the series cells, the coil for maintaining the balance of the voltage between the series cells and by sharing the circuit is smaller than the configuration of the whole. And a coil installed in common to the first and second power storage cell. Charging to electrically connect the coil to one side of the storage cell, and then filled to electrically connect the coil to the other. And installing a plurality of switches for switching the path of the charging current flowing through the coil. In the first charging period, in through the coil forms a path for the charging current flowing in the reference voltage, the second charging period, and forms a path for the charging current flowing through the second cell from the coil, a third charge time, the coil forming the path of the charging current flowing through the reference voltage, and the fourth charging period, and conducting one end of a coil end and a first cell, to the other end of the other end of the first conductivity cell in the coil, the first cell from the coil to form a path for the charging current flowing in. ;
