Embodiment 1
[0025] An energy management control method for a fuel cell bus. The vehicle controller obtains the power battery SOC, the vehicle speed, the power consumption of the motor controller and the power consumption of the accessory load in real time on the CAN bus, and then the vehicle controller determines the power consumption according to the size of the power battery SOC. The first request is for the output power of the fuel cell system, the second request is for the output power of the fuel cell system according to the size of the power battery SOC and the vehicle speed, and the third request is for the output power of the fuel cell system according to the size of the vehicle demand power, where the vehicle demand power is The sum of the power consumed by the motor controller and the power consumed by the accessory load takes the maximum value of the first requested fuel cell system output power, the second requested fuel cell system output power and the third requested fuel cell...
Embodiment 2
[0041] An energy management control method for a fuel cell bus, the steps of which are basically the same as the steps of the energy management control method for a fuel cell bus in Embodiment 1, the difference being that the fuel cell system controller presses the same final request fuel cell System output power control The corresponding execution duration control of the fuel cell system is 300s, and the set time is 30s.
