Connection schemes for Electric Vehicle Supply Equipment

One of the essential issues about operation of electric vehicles in transportation is to attend the demand of charging electric batteries with high reliability. This paper presents different connection schemes to feed the chargers from the distribution system, in three particular cases: private vehicle in residential garage, vehicles in shopping centers, and for bus parking chargers. For the two first cases a flow diagram of design is presented, as the procedure of design in particular cases. Also, a comparison in hours available and costs is made for the case of bus parking. The connection schemes selected are based on the Std. IEEE 493-2007.
