Abstract

According to one embodiment of the invention, there is provided a cell balancing circuit used for balancing a cell. The cell balancing circuit includes a bypass path coupled to the cell, a current regulator coupled to the bypass path, and a bleeding control switch. The current regulator is operable for producing a current and for controlling a conductance status of the bypass path. The bleeding control switch conducts the bypass path in response to the current produced by the current regulator.
