Energy management method, system and vehicle for fuel cell vehicle

Abstract

The present application provides an energy management method, system and vehicle for a fuel cell vehicle, and relates to the field of vehicle technology. The method obtains vehicle operation analysis data of a fuel cell vehicle; calculates the driving power of the driving motor according to the bus voltage, bus current throttle opening information and vehicle slope information of the driving motor; calculates the energy consumption power of other energy consumption systems according to the bus voltage of the power battery and the energy consumption information of other energy consumption systems; performs weighted correction on the driving power and energy consumption power of the driving motor according to the vehicle driving mode, driving power correction coefficient and other power correction coefficients, and determines the target vehicle required power; determines the fuel cell stack required power according to the current state of charge value of the power battery, the target vehicle required power and the vehicle driving mode; controls the fuel cell to output power according to the stack required power. Thus, the vehicle operation is more efficient and the operating cost is reduced.
