In order to introduce and expand the use of natural energy, research has recently been conducted on smart communities that manage the energy balance in a specific region.For a system combining photovoltaic power generation (PV) and electric vehicles (EV), we have developed a model to quantitatively evaluate the change in energy use by EV together with other energy in a specific region with multiple EV. Using this model, we have examined a method to optimize PV use in the case of conversion to EV use based on data of actual vehicle movement.As a result, for designing a combined system PV and EV, we have defined two new indexes: PV rate of electric consumption by EV, and EV usage rate of PV. By using the new indexes, we have shown that it is possible to design the installation site, scale of PV and battery capacity of EV according to the use of EV.
