Abstract
In view of the problem of insufficient driving mileage of pure electric tractor, the output performance of fuel cell and storage battery was analyzed. The structural and power flow of the fuel cell/storage battery hybrid electric tractor powertrain system were designed. Considering the principle of maintaining the optimum performance of the fuel cell system and ensuring the reasonable charging and discharging of the storage battery, an energy management strategy based on fuzzy control was developed. The simulation results show that under the working condition of field work, compared with the switch control strategy, the equivalent hydrogen consumption of the energy management strategy designed in this paper is reduced by 12. 84% and the variance of equivalent hydrogen consumption is reduced by 20. 24%. Under the working condition of the transport operation, compared with the switch control strategy, the equivalent hydrogen consumption of the energy management strategy designed is reduced by 11. 11%.
