The increased demand for efficient and sustainable agricultural machinery has driven the development of hybrid tractors, integrating electrical systems to improve performance and sustainability. This thesis focuses on the dimensioning of an electric powertrain for a hybrid tractor, improving power delivery, energy management, and efficiency. A key topic in this thesis is the development and analysis of duty cycles, which represent real world operational conditions and serve as the structure for system sizing, design and validation.
Starting from the mission profiles of the tractor and subsequently studying various tractor duty cycles, including power demands, transients, and energy, this research identifies the critical requirements for energy storage system sizing, and electric motor performance.
The results demonstrate the importance of accurately modeling duty cycles to optimize high voltage components selection, improve simulation activities, and simplify integration. By aligning the system’s electrical architecture with the load profiles, this study contributes to the development of more efficient and cost effective hybrid tractors, supporting the transition toward sustainable and high-performance agricultural technology.
