Abstract
The scientific aim of this work is to review the technological transition from internal combustion engine (ICE) tractors to battery electric tractors (BETs), with a focus on powertrain technologies, traction motors, and power converter topologies, in the context of advancing sustainable farming practices. The subject of the research was to obtain a comprehensive understanding of the benefits and challenges associated with BETs, including their impact on reducing emissions and enhancing efficiency in agricultural operations. This study extends the existing research in the electrification of agricultural machinery by exploring cutting-edge charging strategies, particularly those integrated with renewable energy sources such as solar and wind. The advantages and limitations of these charging methods are thoroughly analysed, with solar charging identified as a promising solution for BETs. Furthermore, the research discusses energy transmission solutions necessary to support uninterrupted fieldwork. This comprehensive review aims to guide researchers and developers in advancing electric tractor technology, ultimately fostering the adoption of sustainable agricultural practices. The study concludes by offering insights into the future development of compact electric tractors (ETs) and hybrid electric tractors (HETs), emphasizing their potential to enable zero-emission farming while improving agricultural productivity.
