Hybridization factor and performances of hybrid electric telescopic heavy vehicles

In the present paper is studied the effect of electric hybridization on dynamic performances of a telescopic vehicle. A new hybridization factor for working vehicle is introduced taking into account both drive and loading requirements. The numerical MATLAB model is used to simulate the performance level of the vehicle in different conditions. The research is inserted in the frame of a cooperation project between Politecnico di Torino and the main producer of telehandler in Italy, Merlo. Simulations and tests have been performed in different condition in order to realize a typical cycle for a telehandler. The comparison of experimental and simulated results shows a very good agreement in different operation conditions. The performance level of the hybrid vehicle satisfies the requirement and reaches the same performance level of a conventional telescopic machine but with a remarkable reduction of fuel consumption.
