Abstract
© 2018 IEEE.This study was conducted to develop a method for calculating appropriate engine power capacity or engine sizing for range extender application. This method was developed by considering electric vehicle’s specification, driving cycle, road’s gradient profile, electrical components consumption, and powertrain component’s efficiency. The method that had been made is then tested with a case study. Case study for this research was modified a medium-size electric bus with the capacity of 36 people to become range-extended electric bus. Simulation part of this case study was completed by using AVL Cruise software. The operating track used is located in the popular tourist area in Bali. This track was selected because Bali is the leading tourist area in Indonesia and to support Bali as the pioneer in green tourism. Engine power obtained from the calculation is 45,4 kW if the used assumptions were Japan 08 as the driving cycle and road’s gradient profile is 0% along the path and 46 kW if assuming road’s gradient profile is the average gradient.
