Modeling of an Electric Tractor and Determining Energy Consumption Values In Different Duties

Abstract

In this study, a model of an electric tractor was created in MATLAB / Simulink environment, and performance and fuel consumption values were determined. The power transmission system, control unit, electric motor model, energy consumption, and battery subsystems of the electric tractor are included. Reference is made to a study in the literature, as there is no standardized test procedure for tractors. The energy consumption values of the electric tractor for rotary harrow, atomizer, and shredder duties have been examined. In determining the performance of the electric tractor, only the maximum speed value was included. If the reduction ratio of the electric tractor is 50, 60, 70, 80, 90, 100, the maximum speed values and the amount of energy consumed during the process of different duties were determined and evaluated. If the reduction ratio is below 50, no results could be obtained because he could not fulfill his duties in this study. It has been determined that if the reduction ratio is 50, the electric tractor consumes 3.985, 1.266, and 3.787 kWh energy in rotary harrow, atomizer, and shredder duties, respectively. It has been determined that if the reduction ratio is 100, the electric tractor consumes 3.604, 1.145, and 3.535 kWh energy in rotary harrow, atomizer, and shredder duties, respectively. It is concluded that if the reduction ratio of the electric tractor is 50, 60, 7, 80, 90, and 100, it reaches the maximum speed values of 62.
