Design and Prototyping of an Electric City Car for Two Passengers

Abstract

Land transport has contributed to air pollution that occurs. This forced the car manufacturers to improve the quality of their products in order to pass the exhaust emissions standards. In addition to exhaust emissions, the limited source of vehicle fuel energy is the reason some researchers develop electric cars. This article conveys the results of research on prototyping an electric city car for two passengers with wheel hub motor type configuration as our research pilot project related to electric cars. The data acquisition aids made are equipped with a LabVIEW-based human-machine interface that makes it easier for researchers to monitor the consumption of electric cars in real-time. Based on the design process, manufacture, until testing, the value of drag coefficient is 0.47; testing for curb-weight is 510 kg; maximum speed is 75.3 km/hour; the maximum power is 3.03 kW at 602 rpm wheel speed; and the maximum torque is 50.8 Nm at a wheel speed of 516 rpm. For the state of charge, this prototype of an electric city car is capable of traveling up to 42.4 km from 100% to 20% SOC.
