Le véhicule électrique : un nouvel équipement des BEPOS pour valoriser le PV et favoriser la mutualisation énergétique

Building and Transportation are the main energy consumers and GHG emitters of households and France. Many efforts are made to improve energy performance of buildings, but the location of these buildings may erase these benefits: 80 kWh/m²/yr of energy savings in a building is wiped off by travelling 20 km by car every day, for a year. The present study aims to assess the energy balance of electric vehicle coupled with BIPV. TRNSYS software was used to assess the source of energy (PV, Grid, EV battery) involved when an electric vehicle is used for commuting. The VE battery is used as a power source to minimize the energy needs from the power grid during peaks of electricity demand. Twelve scenarios have been examined in order to integrate assumptions on plug-in, climate and commuting distance. Finally, the influence of efficiency reduction due to aging of PV cells has been evaluated on a case.
