More specifically, the method for controlling a cell balancing for a high voltage battery is capable of: reducing the number of resistance elements; and smoothly performing a circuit operation to solve a voltage variation between a plurality of cells included in the high voltage battery without a short circuit phenomenon. The method for controlling a cell balancing for a high voltage battery includes the steps of: measuring first to n^th cell voltages of a high voltage battery; and discharging a voltage of a certain cell to the side having a resistance by turning on a switch connected to the certain cell by a control signal of a switch control unit if the voltage of the certain cell is higher than a reference voltage among the measured cell voltages, wherein first to n^th switches connected to the first to n^th cells are divided into two groups of even n^th switches and odd n^th switches, and only the switch connected to the certain cell is selectively turned on or off by controlling the adjacent even n^th switches to be turned on/off or by controlling the adjacent odd n^th switches to be turned on/off when a cell balancing for the certain cell is performed.
