Evaluation of energy-economic parameters of tractor with electrically driven power unit

Abstract

The development of agro-industrial complex in modern conditionsneeds a large share of low traction class tractors. Manufacturers in their turn strive to fill the market with tractors with good consumer properties. The use of electric drive on tractors is a relatively new trend with many unresolved issues in various areasof this subject. In this paper the questions on prospects of using electric motors as a drive of tractor power unit are touched upon. Energy equipment and general preparedness for transition of tractors to such systems are considered. The question of comparison of basic parameters of electric and diesel engines, consisting in one power category, is considered. The methodology of estimation of energy-economic characteristics of a tractor with electric drive power unit in relation to a conventional tractor with dieselengine and argumentation of the given parameters are given. The usefulnessof the introduced index is shown, as well as the necessity of its use in order to evaluate the efficiency of engines of different types in a comparative analysis. This paper will be useful in the engineering and design field of knowledge related to the design and development of electric drive technologies for mobile machines.
