This study evaluated the motor and battery performance of a 25 kW electric tractor. A load measurement system was used for load data acquisition. Field tests were performed to evaluate motor and battery performance for major agricultural operations such as plow and rotary tillage. The distribution of load data for sub-compact internal combustion engine (ICE) tractor and electric tractor was compared by analyzing IQR (Interquartile range) for plow and rotary tillage. Also, a 1D simulation model for an electric tractor was developed to analyze battery SOC (State of Charge) level and motor efficiency using the measured load data using the electric tractor. The results showed that the IQR for rear axle torque and rotational speed was higher for ICE tractor during plow tillage, and the IQR for front and rear axle torque during rotary tillage was higher for ICE tractor. The simulation result of the SOC level indicated that both plow and rotary tillage operations could be performed for more than 1.5 hours continuously. Motor efficiency using the motor T-N curve and motor efficiency map indicated that simulation data for both agricultural operations were within an optimal efficiency range of 2,000 rpm to 4,000 rpm, where the motor efficiency ranges were between 96% and 98% for both operations. These results demonstrated that the electric tractor performed equivalent to an ICE tractor, indicating that it could effectively replace ICE tractors in a practical agricultural environment.
