Abstract: PURPOSE: A method for controlling a high voltage battery is provided to prevent the available power of a battery controller from drastically changing by maintaining the available power of the battery controller with a previous power limit value in a holding region for limiting power. CONSTITUTION: If a battery voltage is in a holding region for limiting power, the available charge power of a battery controller is controlled to be in a previous power limit value. The holing region for limiting power is a region between a limit voltage and a recovery voltage. If the battery voltage is more than the limit voltage, the charge power of the battery controller decreases with a slew rate. If the battery voltage is less than the recovery voltage, the charge power of the battery controller increases with a slew rate. The battery voltage is a region between the limit voltage and the recovery voltage, the charge power is maintained with a previous power limit value.

Abstract: PURPOSE: A cell balancing method of a battery pack for a hybrid vehicle is provided to minimize voltage deviation between cells inside a battery pack by performing the cell balancing until the measured voltage deviation between the cells is a value obtained by subtracting the preset size from the fixed size. CONSTITUTION: A cell voltage is measured by determining a key on state(S100). The cell voltage is measured by determining whether the current is a constant valve or less for one minute or more(S110). It is determined whether the voltage deviation between the cells is a preset size or more(S120). It is determined whether the fault is not generated and the state of charge is above 20%(S130). The corresponding cell is discharged by the cell balancing if the voltage deviation between the cells is above the preset size based on the minimum voltage cell(S140). The cell balancing is released by determining whether the voltage deviation between cells is the value obtained by subtracting the preset size from the fixed size(S150).
