Abstract: In this paper, the influence of different test methods on driving range and energy consumption of a certain type of city bus is studied by consecutive cycles procedure (CCP) and shortened test procedure (STP). By analyzing the test results, it is found that no matter which test method is used, relatively accurate test results can be obtained, and the difference is less than 5%. In the case of small difference in equivalent energy consumption, if the vehicle's rechargeable energy storage system (REESS) can be discharged more by using a lower constant speed segment, the driving range will be larger, but the energy consumption obtained based on external power supply may also increase. In the STP, because the energy consumption of the second cycle working condition occupies a much higher proportion of equivalent energy consumption than that of the first cycle working condition, it has the greatest impact on the final equivalent energy consumption. Therefore, reasonable optimization of energy consumption at low power (20% ～ 30%) can effectively control the equivalent energy consumption in the test and obtain a more ideal driving range.
