Energy Management Strategy for Hybrid Engineering Vehicles with Composite Energy Storage
To improve the energy utilization efficiency of hybrid engineering vehicles with composite energy storage, a new energy management strategy based on fuzzy control theory was proposed. The vehicle model of the hybrid loader was established with MATLAB/Simulink and the energy distribution of it in the “V” type working condition was simulated. The fuel consumption of the traditional loader and the hybrid loader with the proposed energy management strategy were simulated and compared in two typical working cycles. A hardware-in-loop simulation platform was built to validate the presented energy management strategy. The simulation and experimental results show that the energy management strategy used in the hybrid loader can make various power devices work in high efficiency, which significantly improves the fuel economy of the vehicle.
