Realization of a sustainable low-carbon society is required globally, and energy consumption reduction derived from fossil fuels has been emphasized. In the transportation sector, which accounts for a large percentage of energy consumption, EVs with high environmental performance has been popularized and it is important to use renewable energy for its charging effectively. In this research, we proposed a coupled simulation model that can represent interactions between transport and electric power systems. Since the charging event is coupled to the electric power system mechanism, the spread of EVs will affect not only the road transport network but also the electric power system. As a result of the numerical experiments, it was implied that the concentration of low-output charge after returning home might cause a voltage drop in the distribution system. This phenomenon became more prominent as the penetration rate of EV increased, and the possibility that it deviates from the legal range of the reference voltage is shown in some scenarios.
