TeleWatt: An innovative electric vehicle charging infrastructure over public lighting systems

The growth of the Electric Vehicle (EV)´s market is strongly conditioned by the availability of cost-effective and reliable charging infrastructures. In the current state of the technology, the limited capacity of the batteries limits EV´s market to urban moves. The rapid deployment of charging stations in urban areas is a real challenge. In this paper, we introduce an original approach consisting in reusing existing public lighting infrastructures for that purpose. Two main advantages characterize our solution. First, charging stations can be deployed rapidly without costly civil engineering. Second, a fraction of the power non consumed by the lamps at night can be used for the benefit of the charging stations. Meanwhile, such an approach must be achieved while guaranteeing the stability and quality of the lighting system.
