Modular distribution system for EV parks

Very many papers on Electric Vehicle (EV) parks deal with the problems of the electric energy management, of the systems integrating in microgrids with renewable sources. Otherwise, this paper emphases the design of power system supplying many hundred cars in an electrified park. This paper suggests a distribution architecture that aims to design modularity for EVs parks to enable the operation, maintenance and effective supervision and highlights some designing parameters. It deals with the design optimization that needs dedicated distribution topologies and equipment and requires approaches for the car sockets different from the existing charging stations. This paper prospects the promotion of dedicated components in the next times adequate to the specific service such as LV prefabricated busbars for the distribution of electricity to the recharging of the EVs and a review of the supplying wallboxes in near ordinary sockets. It certainly is desirable that extended EV parks have to provide a friendly recharge, low cost, based on a "topping up charge” of the cars in the time of occupation of the parking space. The mobile EVs as all electrical components powered by plug sockets are not part of the electrical system; therefore, the charging protection can be installed on each vehicle. This approach allows reducing sensitively the cost impact of wallboxes on the total cost of the power system and avoiding/limiting the problems of legal responsibility in cases of accidents in recharging processes; it will promote the extension of power parks to thousands of EVs.
