We have developed the dynamic simulator to evaluate the drive performance of the electric two-wheelers through the HIL(Hardware in the loop) test on the motor dynamometer with the servo motor. In the HIL test, the servo motor of the dynamometer applies the road load to the motor under test according to the speed and the acceleration of the motor. To check the availability of the developed simulator, we have compared the results of the simulation on the dynamometer with the field tests. In field test, we rode the e-bike with BLDC motor and Li-ion battery and performed the coastdown test in order to find the correlation of the road load and e-bike’s speed. And we carried out the test for the acceleration performance. After the field test, we assigned the correlation of the road load-speed to the dynamic simulator and simulated the e-bike’s drive about the coastdown and the acceleration performance from the standstill. From the comparisons, we concluded our developed simulator was very available for the drive simulation of the e-bike’s drive on the real road.
