Simulation analysis of an improve power tracking strategy for fuel cell heavy-duty trucks

This paper conducts simulation analysis of an improved fuel cell heavy-duty truck power tracking strategy, and elaborates on the proposed energy management strategy. The strategy determines the requested power of the vehicle for fuel power based on factors such as vehicle operating status, vehicle power demand, and power battery SOC. It also formulates fuel power setting rules for parking power generation mode and driving power generation mode respectively. Finally, the effectiveness of the strategy is verified through simulation analysis. The results show that the strategy can effectively reduce the number of load changes of fuel cells, extend their service life, and have limited impact on the overall energy consumption of the vehicle. In addition, the strategy also considers the impact of the power variation time of the fuel cell system and the number of cycles of charging and discharging of the power battery on the overall efficiency of the vehicle, providing a reference for optimizing the energy management strategy of fuel cell heavy-duty trucks.
