<p>A cell balancing circuit with a self-balancing function and a secondary battery with the cell balancing circuit are disclosed. The cell balancing circuit includes a balancing unit provided for every two adjacent unit cells among the unit cells. The balancing unit includes a discharge unit and a voltage-dividing unit. The discharge unit sets a discharge path to discharge only the unit cell with the higher voltage among the two adjacent unit cells. The voltage-dividing unit uses the voltages of the two adjacent unit cells to provide an enable signal to the discharge unit.</p> |
