Abstract: The authors analyze the influence factors of significant deviations for the power test results of electric vehicles on actual roads and on test benches,and design the comparison schemes of power consumption test. The results indicate that more accurate determination of the road resistance coefficient, appropriate road spectrum data processing methods,and the skilled driver can effectively reduce the relative deviation of the power consumption values between the actual road test and the the bench test.
Key words: electric bus; chassis dynamometer; road driving; power consumption test
