Abstract

In this article it is studied the behaviour of a rechargeable battery, which outputs a maximum power capacity of 17 kWh that's being used as the main source of the prototype electric tractor developed at INMA Bucharest. This tractor is equipped with 16 kW electric motor, 4 speed gearbox and 4x4 traction. The charging mode of the battery when it is supplied with different powers from the current source was studied, but also the power delivery mode when the tractor is in operation and different loads occur. The energy consumption of the battery has also been studied, from the moment when the tractor is put into operation, driving on flat asphalt or agricultural land, with or without load and also in extreme traction conditions, for ploughing or towing heavy loads.

În acest articol este studiat modul de comportare a unei baterii de acumulatori, care poate debita o energie maximă de 17kWh, ce este folosită ca sursă principală de energie la prototipul tractorului electric dezvoltat în cadrul INMA Bucuresti. Tractorul este echipat cu un motor electric cu putere 16kW, cutie de viteze cu 4 trepte și tracțiune 4x4. A fost studiat modul de încărcare al bateriei atunci cand este alimentată cu puteri diferite de la sursa de curent dar și modul de livrare a energiei atunci când tractorul este supus diferitelor regimuri de lucru în functionare. De asemenea a fost studiat consumul de energie din baterie de la momentul cand tractorul este pus în funcțiune, rularea pe teren plan, asfaltat sau teren agricol, cu sau fără sarcină dar și în condiții extreme de tracțiune, la lucrări de arat sau tractarea unor sarcini mari.
