Abstract
A method of controlling a battery charge level of a hybrid electric vehicle includes: monitoring a quantity of current accumulated for a predetermined time based on a battery charge/discharge current value; calculating a regenerative charge derating constant; calculating a correction coefficient based on the quantity of current accumulated and a battery state of charge; multiplying the regenerative charge derating constant by the correction coefficient to calculate a final regenerative charge derating constant; and multiplying the final regenerative charge derating constant by a charge power to calculate a final charge power, and selectively restricting the battery charge level based on the final charge power.
