A simulation system, an unmanned aerial vehicle, an unmanned aerial vehicle simulation method, and an unmanned aerial vehicle simulation device. The simulation system comprises: a battery model (102) used for simulating and calculating, according to state information at the previous moment and battery state information at the previous moment of an unmanned aerial vehicle, battery state information at the next moment; and a state model (101) used for simulating and calculating, according to the state information at the previous moment and the battery state information at the next moment of the unmanned aerial vehicle, state information at the next moment. The simulation system performs simulation on the operation of the unmanned aerial vehicle by using battery parameters as a part of the simulation system, such that the simulation becomes more realistic.
