Document Type and Number:
Japanese Patent JP2010522528
Kind Code:
A
Abstract:
A method of balancing a state of charge (SOC) of a plurality of cells connected in series, including identifying an undercharged cell from the plurality of cells to charge, electrically connecting a positive side of the undercharged cell to a positive bus, electrically connecting a negative side of the undercharged cell to a negative bus, electrically connecting an inductor to a voltage source during a first time period; electrically disconnecting the inductor from the voltage source in response to an elapse of the first time period, and maintaining the disconnection of the inductor from the plurality of cells for a second time period corresponding generally to the time for the inductor to discharge energy to the undercharged cell.
