This paper contains an investigation about using electric buses alternatively in a BRT line in Tehran. In order to reach this purpose driving cycle of electric bus for different bus routes are simulated and studied. Also with the aim to choose the pilot route, several criteria such as, air and noise pollution, traffic characteristics, numbers of passengers on each route have been considered. Hence, Azadi terminal to Tehran-Pars intersection route has been selected. In addition, characteristics and specifications of proposed propulsion and energy storage system based on driving cycle simulation results of different routes in Tehran are determined.
In this study, designing a storage system (battery) and main characteristics including total capacity and battery capacity based on the amount of daily activity, number of daily round trips, average energy consumption of the route and daily electrical power consumption of each bus and the battery charging and discharging ranges and total inverter and motor efficiency will be determined.
