This study aimed to evaluate the performance of an electric tractor equipped with an E-axle system through simulations in a MATLAB/Simulink environment. Travel speed conditions were set at 5 km/h and 7 km/h, which reflected typical speeds for plow tillage. The analysis focused on comparing performances of key components and the overall vehicle under these conditions. Results showed that reducing the travel speed decreased slip and improved tractive efficiency. At a travel speed of 5 km/h, the maximum slip of the front E-axle was reduced by 35% with average slip reduced by 45%. For the rear E-axle, the maximum and average slips were reduced by 85% and 78%, respectively. In addition, the average tractive efficiency increased to 85.1% at 5 km/h, which was approximately 14% higher than that at 7 km/h. The reduction in initial slip also improved energy efficiency. The average traction force was consistent over 26.6 kN for both speed conditions, demonstrating that similar traction could be maintained even at a reduced travel speed. These findings suggest that optimizing the travel speed of E-axle based electric tractors can significantly enhance operational efficiency and energy management. This study provides essential data for developing slip control algorithms for E-axle systems and electric tractors. Future studies need to be conducted for experimental validation and further analysis to support these findings.
