Energy management strategy for fuel cell commercial vehicle based on dynamic programming

  • To test the rationality of the power system for a fuel cell commercial vehicle, the models of energy source (including fuel cell stack and battery pack), electric motor system (including electric motor and its controller) and driveline are built in Matlab. A global optimization energy management strategy based on dynamic programing is adopt to analysis the vehicle's fuel economy with the European typical drive cycle under three load modes (including no-load, half-load and full-load). Simulation results show that the energy source employed satisfy the vehicle's power requirements at the selected drive cycle, while with the increase of on-board load, the terminal SOC of battery gradually deviates from the initial value, which will limit the commercial vehicle's dynamic performance in the long term cycles with a large on-board load. Verification results for the vehicle point that great power on-board fuel cell stack should be considered in the following research and vehicle verification.
