In order to analyse and improve the energy efficiency of electric vehicles (EVs), an efficient, effective and accurate simulation model of vehicular systems is established from the energy flow point of view. The proposed model includes sub-systems of energy storage, energy consumption, energy transmission, vehicle dynamics, driver model, and vehicle controller. A case study, based on Nissan Leaf, is implemented for validation of the proposed model. Finally, the energy flow and consumption distributions are demonstrated. Due to its openness and expansibility, the model can be used for design optimization of EVs and the results obtained would provide a guidance to design an EV in a more systematic and optimal way.
