The use of electric vehicles for public transportation is a practice that has spread widely in recent years, in response to the needs ofreducing global polluting gases emissions and decrease vehicle ownership. However, nowadays some issues need to be addressedto provide this type of services with electric vehicles, such as the low-profit margins that can be achieved by the fleet operators.This paper addresses this issue giving to the public EVs the feature of providing power to the electrical network. Hence, a controlsystem based on optimization is proposed to perform profitable management of the charge and discharge of the EVs that are usedto provide public transport services by an operator, which also have the possibility of delivering power to the electrical network.Furthermore, this control system will also take into account the batteries wear cost.
