Sažetak
This paper presents a hypothetical conversion of a conventional articulated forestry tractor known as skidder to its hybrid counterpart by incorporating a battery energy storage system. Starting from the basic parameters of 84 kW diesel-powered skidder currently found in the national forestry company fleet, the quasi-static model of the skidder is derived and validated. The conventional skidder model is then converted to its hybrid counterpart by adding a battery energy storage system in parallel with the electrical power generator and an adequate energy management control strategy. The hybrid skidder power-train components are also appropriately re-sized in order to meet comparable traction force and power performance. Both the conventional and hybridized skidder models are then used for the purpose of comparative analysis of main vehicle characteristics for the off-road driving scenario, which includes realistic slope and terrain limitations. The obtained simulation results are used to gain insights about the possible advantages of the proposed conversion/drive-train hybridization in terms of feasible reduction of fuel consumption and related CO 2 emissions, while also considering additional hybridization costs and return of investment period.
