Measurement uncertainty could reasonably characterize the reliability of measurement results.Various influencing factors of battery electric vehicles energy consumption and range measurement results were analyzed and evaluated.Combined with the test standard and the actual measurement process,the measurement mathematical model and uncertainty calculation mathematical model were established.Through the evaluation and combine of uncertainty components,the measurement uncertainty evaluation results were obtained.The results showed that the synthetic relative standard uncertainty was within 1%,the class B uncertainty component introduced by the test system error was small,but the uncertainty component introduced by the measurement repeatability factor accounted for a large proportion,which had a great influence on the results.
