The evaluation of EV energy consumption economy is emphasized because of energy and environmental issues. The work studies the energy consumption economy based on the method of test bench simulation

which included a dynamometer and related software. Taking the ECUV vehicle as an object

hundred kilometer energy consumption is tested in different vehicle speeds and driving cycles.Energy consumption economic characteristic curve is depicted in figure and drving range is calculated. Vehicle mass influence on the energy consumption economy is analyzed through testing the EVs hundred kilometer energy consumption. The result is used to improve the ECUV vehicle energy consumption performance and increase the driving range

and also provides the references for the development of other EVs.
