摘要
The present invention relates to a method and apparatus for controlling power allocation of a fuel cell-battery hybrid system. A mode switching output value, which is a reference for switching of power supply status and power allocation, is set within a range below a maximum power value of a motor supplied with a constant voltage from the fuel cell and/or the battery. A requested output value is extracted in real time. The mode switching output value is compared with the requested output value. When the requested output value is less than the mode switching output value, a fuel cell converter is operated, and an operation of a battery converter is stopped. When the requested output value is equal to or greater than the mode switching output value, both the fuel cell converter and the battery converter are simultaneously operated in a predetermined output ratio.
