Research on energy-saving of parallel hybrid power loader

To improve the energy-saving effect of loaders, this paper study the hybrid power technology in-depth. In this paper a parallel hybrid power loader is investigated as research object, operating condition of a 5 tons loader is analyzed. Parameter matching and control strategy based on super capacitor charge status and load conditions are proposed. Results show that the hybrid power loader uses about 10.4% less fuel than traditional loader and has good fuel economy, and the super capacitance works stability within the setting range. Energy utilization is enhanced and energy-saving effect is improved.
