Abstract: Prediction of range and remaining battery state-of-charge after trip completion is necessary beforehand for electric vehicle (EV) deployment towards trip performing. Present paper presents an EV drive model for a micro-trip which includes all possible aspects (such as route information, traffic norms, driving behaviour and external disturbances) along with the regenerative braking for a (pure) electric vehicle. Driver's primary inputs to the model are the vehicle initial speed, initial battery state-of-charge, driving strategy to be followed and remaining distance of the route to be performed. Data related to the corresponding route are collected and fed to the model as secondary inputs. The model is validated by comparing the simulated data with that of experimental values of a commercial EV and analysing the variations of critical parameters of EV components. The importance of EV drive model is established by analysing the effects of route parameters and driving behaviour on EV range.
