Abstract

The present invention answers the need for the existence of a network for charging electric vehicles (EV), particularly with regard to the so-called fast charging (20 to 30 minutes). Therefore, this station is intended for, inter alia, parking areas of public and private buildings, and fossil fuels service stations, such places where the slow charging is not very viable, since this type of charging (6 to 8 hours) will be done mostly at night. The present invention envisages the charging of EVs within a short period of time and with the particularity of being renewable energy produced on site, being possible to produce in one place the electrical energy necessary do power the EVs, since it includes structures of photovoltaic panels and equipment for the transformation of energy and the fast charging of the existing DC batteries in the EVs.
