Modeling of a Permanent Magnet Synchronous Motor of an E-Scooter for Simulation with Battery Aging Model

For the growing market of electric two-wheelers (e-scooters) especially in China, the paper presents an implementation of a time efficient powertrain model. The model consists of an electric motor, power electronics and a Li-ion battery with aging prediction. Depending on the intended use of the models, two different accuracy levels requiring different computational power and computation time are introduced. As motor model a Permanent Magnet Synchronous Motor design is used. An empirical aging model for a Lithium Manganese Oxide cell is presented, which is based on aging measurements. Together, the models provide a possibility to evaluate the long-term cell aging behavior under realistic drive cycles taking motor effects into account.
