Abstract
The growing problem of climate change associated with high oil prices is
increasing the interest and research on electric vehicles (EVs). EVs due to the
storage capacity provided by the batteries can supply or store electricity when
parked. At the same time the electric power grid and light vehicle fleet can be
exceptionally complementary as systems for managing energy and power. In the
case of isolated systems, such as the islands, the introduction of EVs could be
very beneficial not only environmentally since they are competing directly with
the internal combustion engine vehicles but also economically and in the energy
mixture of the local system. But to drive these vehicles, it is necessary to have a
charged battery. To assure this, an infrastructure system is needed, connected to
the grid, that can provide a parking charge (so that EVs can charge at homes,
offices, public parks, etc) and an ongoing charge (so that travellers can refill their
EV power in a fast process, like a fast charging station or a switching battery
facility). Fast charging is mainly for commercial and public applications and is
intended to perform similarly to a commercial gasoline service station, aiming to
achieve a 50% charge in an EV’s battery in 10 to 15 minutes. This work studies
and evaluates the fast charging infrastructure and the developed methodology
that can optimize the station profit and still provide a charging price lower than
the fuel price at the gas stations. The model simulates the fast charging price for
drivers at the station and compares with the house night charging and with the
internal combustion engine (ICE) fuel (diesel and gasoline) at the gas stations,
for the Portuguese case.
