Desenvolvimento de uma estação de recarga modo 3 para veículos elétricos

Abstract

The amount of electric vehicles (EV’s) sold annually has grown exponentially over the last decade around the world, and one of the main questions for customers interested in pur- chasing an EV is how they can recharge their vehicles at home. There are two economically viable ways to do this: one is to use the portable charger that is provided by the manufac- turer together with the VE, and the other one is to use an electric vehicle charging station, being the second option the fastest way between the two. This way, there will be an increase in demand for this equipment in the coming years. With this in mind, this work has the objective of developing an electric vehicle charging station suitable for installation in a residential environment. An electric vehicle charging station is nothing more than equipment that is connected to the building’s electrical grid and makes energy available safely and reliably to the EV so that it can recharge its batteries. Following the recommendations and requirements of international standards were designed the protection circuits, communication with the EV, and detection of the recharging cable. The design of a human-machine interface and an energy consumption measurement circuit were also carried out, both toprovide to the user with information on recharging and thus improving the user experiencewhen using the charging station. Finally, all the tests required by international standardswere carried out in order to verify that the recharging station is complying with all the requi-rements.
