This study aimed to verify the agricultural working performance of an electric tractor by developing a 1-D power transmission system simulation model using SimulationX (ver. 4.4, ESI ITI GmbH, Germany). A load measurement system was installed on the electric tractor to measure real-time data during plow tillage, including axle torque and the state of charge (SOC) level of the battery. The t-tests were conducted to compare the measured and simulated axle torques and validated the simulation model. The p-values for the front and rear axles were 0.18 and 0.19, respectively, indicating no statistically significant differences. Although the measured and simulated SOC did not perfectly match, the trends showed similar patterns.

The divergences in SOC were mainly due to the resolution limitations of the SOC sensor during measurement. Based on both measured and simulated results, the estimated workable time for plow tillage using the electric tractor was approximately 2 hours.
