Summary:After analyzing the working condition of the conventional diesel forklift, an energy recovery system in hybrid forklift is considered and its simulation model is built. Then, the control strategy for the proposed energy recovery system is discussed, which is validated and evaluated by simulation. The simulation results show that the proposed control strategy can achieve balance of the power and keep the state of charge (SOC) of ultra capacitor in a reasonable range, and the fuel consumption can be reduced by about 20.8% compared with the conventional diesel forklift. Finally, the feasibility of the simulation results is experimentally verified based on the lifting energy recovery system.
