Development of the performance simulator for electric scooters with an in-wheel motor

Due to the increasing use of fossil fuel, carbon dioxide emission also increased and environmental problems have emerged as social issues. Accordingly, the research about electric vehicles as personal transportation has been actively performed. An electric scooter is not as complex as an automobile, but it takes a lot of time and costs to design and develop a new vehicle due to trial and error in selecting the specifications of core components according to consumer’s requirements. In this paper, a performance simulator for an electric scooter with an in-wheel motor at the rear wheel was developed and the simulation results were verified through experiments. For a longer travelling distance with the same energy source, the regenerative braking algorithm that converts kinetic energy into electric energy during braking was applied. The usefulness of the regenerative braking control algorithm was verified through various simulation results.
