Development of Drive Cycle and Resultant Powertrain Calculations of Electric Bicycle

To model the powertrain for an electric bicycle, it was observed that the drive cycle was a critical input required to get accurate results. While trying to find a priorly available drive cycle in the past literature, it was observed that there were no good reference points for powertrain calculations of an electric bicycle and the corresponding drive cycle used. Hence, this paper demonstrates the process of creating a drive cycle that is used to then obtain the powertrain requirements of an electric bicycle. The process of creating a drive cycle consists of data collection, analysis, and generation of the final drive cycle. The features of the drive cycle are compared with standard drive cycles like World Motorcycle Drive Cycle (WMTC). This drive cycle is then used as input to a powertrain model which was built. The powertrain model consists of 4 components, namely the chassis, transmission, motor, and battery. The salient features of each individual component are explained briefly. The battery and motor requirements pertaining to our unique inputs are shown and the variation of battery power with respect to bicycle speed is explained graphically.
