Simulation Models for the Evaluation of Energy Consumptions of Electric Buses in Different Urban Traffic Scenarios

The paper presents a methodology to estimate the energy consumptions of a full electric bus in different traffic and operating conditions. Starting from driving cycles, evaluated through a simulation model developed in Aimsun, the Matlab/Simulink energy model of the bus calculates the main electrical and mechanical performance indicators such as the state of charge of the battery as well as power and torque provided by the electric motor. The methodology is applied to a real case study, that is an Italian town in the North of Italy, for which different traffic conditions and drivers' behaviors are analyzed.
