  7. 5. Systemutformning av autonom batteridriven traktor inom lantbruket

    L3-uppsats, SLU/Dept. of Energy and Technology

    Författare :Martin Ericson; [2018]
    Nyckelord :systemutformning; batteridrift; framtidens lantbruk;

    Sammanfattning : In this study, data from different studies were used to find how much energy that a conventional tractor required per hectare when it was performing different operations on a field. Data for operation speed and power demand were taken from an earlier study for each task of the tractor model Valtra 6600. LÄS MER
