The focus of this paper is the potential electrification of specialized agricultural tractors involved in vineyards and orchards. This category of machinery has not received research attention to date; however, regulations are encouraging lower emissions and higher efficiency, requiring the adoption of new technologies. Traction makes up only a limited part of this application, and the working cycle is not trivial; therefore, the design of the system is not straightforward. This study takes advantage of experimental measurements carried out under real operating conditions on a traditional specialized tractor, which was chosen as performance target. The performance requirements of the hybrid powertrain components are investigated, with particular focus placed on the electric motor. According to the dimension constraints, the design of the electric motor is carried out considering the requirements in terms of its thermal-equivalent torque and overload capability. The results are validated through a detailed thermal simulation under real duty cycles.

Electrified vehicles have undergone great evolution during the last decade because of the increasing attention paid on environmental sustainability, greenhouse gas emissions and air pollution. Emission regulations are becoming increasingly tight, and governments have been allocating multiple funds to facilitate the spreading of the so-called green mobility. In this context, steering towards electrified solutions not only for passenger vehicles, but also for compact off-highway vehicles extensively employed, for instance, on construction sites located in urban areas, warehouses, and greenhouses, is essential even if seldom considered. Moreover, the electrification of compact off-highway machinery may allow manufacturers to increase their expertise in and lower the costs of these alternative solutions, while gathering useful data to be applied in bigger and more remunerative off-highway vehicles. In fact, while electric automobiles are as of now real alternatives for buyers, off-highway vehicles, regardless of the application, are mostly in the research and experimental phase, with few of them already on the market. This delay, in comparison with the passenger automotive industry, is caused by different factors, mostly related to the different tasks of off-highway vehicles in terms of duty cycles, productivity performance parameters and user acceptability. The aim of this paper is to give an overview of the many aspects of the electrification of compact off-highway vehicles, to highlight the key differences between on-highway and off-highway vehicles and to summarize in a single source of information the multiple solutions investigated by researchers and manufacturers.

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.
