The invention provides a battery storage and concentrated charging optimization method for an electric bus charging and converting station. The method involves making an optimization principle on the basis of formulation of an optimization target; constructing an electric bus charging and converting station parameter design model; based on a power converting station, serving a single route, and under the condition that power conversion and charging are carried out when a vehicle only runs a round, giving calculation methods of a vehicle quantity, a standby battery quantity, a power conversion station quantity and charging power in different conditions; and finally giving an electric bus charging and converting station operation mode. By using the method provided by the invention, the problems existing in the prior art are solved.
