Abstract

In this presentation, the effects of hybridization on fuel economy and dynamic performances of vehicles will be discussed. The R&D activity is part of a long term cooperation project between University Politecnico di Torino and the main telescopic producer in Italy Merlo Spa. The simulation and test are performed on the basis of a patented telescopic hybrid solution suitable for handling and agricultural applications. The system offers a method of greatest efficiency and least emissions. Power can split solely to the driveline or partially to driveline and machine hydraulics, and any excess power is back into battery charging. In ‘Full Electric’ mode, only the electric motor provides drive and the diesel engine is turned off. This mode is ideal for indoor working inside buildings or tunnels, or anywhere where noise and exhaust emission must be minimized. and the autonomy is that given by lithium batteries. The effects of hybridization due to combined analytical and simulation approach will also be covered. The analytical approach is based on the energy balance equations and considers all energy paths in the HEVs from the energy sources to wheels, whereas the simulation approach is designed and realized in MATLAB/ SIMULINK environment. Furthermore, in telescopic heavy vehicle, a series of experimental proofs are accomplished to gather up information to compare and analyze the results of analytical and simulation approach to experimental testing. Several tests have been performed first of all in order to identify the model. Secondly to characterize the performance and compare the dynamic performance with the conventional dieselhydraulic machine performed in different condition of a typical cycle for a telehandler application.
