摘要： The present disclosure relates to a battery assisting apparatus and method for a fuel cell vehicle. An exemplary embodiment of the present disclosure provides a battery assisting apparatus for a fuel cell vehicle, including: a controller configured to determine an increase or decrease of driver's determination to accelerate based on a change rate of motor torque and a change rate of accelerator opening when a battery assistance mode is entered, and to release the battery assistance mode when the driver's determination to accelerate is decreased; and a storage configured to store data and algorithms driven by the controller.

摘要： Disclosed are a control system for a fuel cell including a fuel cell configured to receive a fuel gas and an oxidation gas and generate electric power, a current controller configured to control an output current output from the fuel cell, based on a demanded current of the fuel cell, while maintaining an output voltage output from the fuel cell at a preset voltage or more, and a restriction controller configured to estimate an output current at the preset voltage as a maximum current when the output voltage of the fuel cell drops to become equal to or smaller than the preset voltage, and restrict the output current of the fuel cell to not more than a first restriction current set based on the estimated maximum current, and a control method for a fuel cell.

摘要： A system for controlling electric power of a vehicle having a fuel cell is provided. The system includes a fuel cell that generates electric energy by receiving fuel and oxidizing gas and a battery that receives the electric energy of the fuel cell to charge or discharge the battery for supplying the electric energy. A sensor sense a driving state of the vehicle. A controller controls charging or discharging of the battery based on the driving state sensed by the sensor.
