Fuel cell hybrid power energy control method

The invention relates to a method for controlling a fuel cell hybrid power energy, belonging to a controlling technical field of multi-energy power assembly. An SOC value, a rotate speed Omega of a motor, and a voltage of a bus U are obtained from a CAN network; a throttle opening Psi is obtained from a throttle pedal of the driver; a target torque T and a target power of the entire vehicle P are calculated according to the rotate speed of the motor and the throttle pedal; a target current I of a storage cell is calculated; a target current I of the entire vehicle is calculated; a steady target current I dc of DCDC is calculated; the target torque of the motor and the target current of DCDC are sent to a motor controller and a DCDC controller through the CAN network, and the corresponding torque and current are outputted. Aims at Alpha and Tau, the invention also discloses a parameter optimization method of the method for controlling hybrid energy of the fuel cell, From the aspect of entire vehicle controlling, the invention discloses a controlling hybrid energy method which can both improve the system durability and considerate economical efficiency. Through optimization of parameter matching, the variable load of the fuel cell is prevented from being too intense, and no frequent starting and stopping is required during running process of the vehicle.
