Abstract
We have designed a vehicle using only six rechargeable Ni-MH(Nickel metal hydride)AA batteries as source of power for pico-EV Eco Challenge. In this design, "cheapness, handiness, and simplicity" is thought as important. Specifically, a gear box was used as a power transmission device, a bicycle as a main part frame and maxon DC motor 273752 as an actuator. And, revolving speed of motor was controlled by PWD control using MOS-FET. Next, the running test was done in order to evaluate the quality of the vehicle. As a result, in the regular run, the average velocity was 2.7 km/h and the average power was 9.3W. And, we participated in the eco-challenge convention with the vehicle.
