In this thesis, I compared the use of a tractor unit powered by an internal combustion
engine with that of an electrically powered tractor unit. I began with an overview of the
history of tractor units and internal combustion propulsion. I then continued with the
development and current state of electric vehicles. I described batteries, the charging
infrastructure they utilize, and the different types of propulsion systems used in electric
vehicles. The thesis concludes with SWOT analyses comparing the use of internal
combustion engine tractor units and electric tractor units, based on data obtained
during the research and development of the thesis topic.
