Performance Evaluation and Accuracy Analysis of a Chassis Dynamometer for Light Electric Vehicles

This research focuses on the development of a chassis dynamometer for light electric vehicles (LEV), utilizing the Prony Brake method for torque measurement. The primary goal was to create a robust testing platform that accurately assesses the performance characteristics of LEVs under controlled conditions. The dynamometer’s performance evaluation revealed an average error of 0.55 for RPM readings, indicating a moderate level of variability in the sensor’s accuracy. In contrast, the torque measurement yielded a significantly lower average error of 0.03, demonstrating high precision in capturing torque data. Additionally, a standard deviation of 0.34 was observed during the torque versus RPM assessments, reflecting the consistency of the collected data. These findings validate the effectiveness of the chassis dynamometer in delivering reliable performance metrics for LEVs, providing essential insights for future advancements in electric vehicle technology and performance evaluation methodologies.
