This paper proposes a general procedure to compute the load profile of a bus rapid transit station where a fleet of full-electric buses is charged. Such procedure is divided in two stages. At first, in order to determine if the flash charging is feasible given a certain travel route, the state of charge of a bus during its operation is modeled, based on Geneva's all-electric articulated bus and its flash battery charger. Then, assuming that buses are autonomous and can complete their routes without running out of energy, the point of view of a charging station is taken into account. The objective of the model is to compute the load profile for a station, according to its charging policy and demand. The models are tested with the bus rapid transit system implemented in Bogotá, Colombia. Through the implementation of Monte Carlo simulations, different charging scenarios are considered for this study.
