Design and test of DC motor drive system for agriculture electric vehicle

摘要

This research has been design a 1-seat agriculture electric vehicle modified from ATV using by DC motor 48 V 1, 000 watts. This electric vehicle has 4 batteries of 12 V 40 AH for power source. The size of the vehicle is 0.785 × 1.20 × 0.815 m, weight of about 152 kilograms. The performance test of theagriculture electric vehicle shows that the maximum speed can be achieved at average of 41.5 kilometres per hour, test by people weighting 60 kilogram. The average times for accelerated from 0-20, 0-30 and 0-40 kilometres per hour are 2.66, 4.67 and 5.84 seconds, respectively. The operating time of the electric vehicle can be used at the average of 30.50 minutes; running at an average distance of 13 kilometres with charged battery takes an average 29.88 minutes.
