ENERGY CONTROL METHOD FOR HYBRID BUS USING HYDROGEN FUEL BATTERY AND POWER BATTERY

An energy control method for a hybrid bus using a hydrogen fuel battery and a power battery are disclosed. The method includes the following steps: collecting motor power data; selecting an SOC value from a certain range around an average motor power value, and performing interpolation assignment on a pile power range; adding vehicle parking determination; locking a pile variable-load frequency standard, and assessing whether requirements are satisfied; determining SOH state of the battery; and adding an operation of forced pile startup during low SOC. Based on a pile system control unit, BMS and a vehicle control unit (VCU) system, the present invention can designate and optimize an energy control strategy by means of real-time data, and determine the power state of the vehicle through VCU, and add an operation of low-power power supply by the pile during parking and an operation of forced pile startup during low SOC.
