The transition period from conventional vehicles to electric vehicles in Indonesia is accompanied by various issues. One of them is the range anxiety felt by potential electric vehicle users. Range anxiety exists because the user does not know whether the energy in the electric vehicle is sufficient or not to reach their destination. To overcome this, in this study, a dynamic model of electric vehicles that can estimate vehicle energy consumption is made. Apart from being able to help the process of selecting electric vehicle components, performance evaluation can also be carried out before building an electric vehicle. The dynamic model will be used to estimate the energy consumption of electric buses. The model was developed by applying the principles of longitudinal dynamics of vehicles, electric motors, and batteries from a system-level perspective. Model validation is carried out by comparing the parameters of the simulation results with the actual data from the electric bus test results. The validated model is used to evaluate electric bus performance including system efficiency and electric bus energy consumption.
