Environmental pollution issues such as global warming and particular matter (PM) have recently brought a lot of attention to the government’s eco-friendly policies all. In addition to environmentally friendly energy, various policies like subsidy support policies are being implemented to promote the use of electric vehicles. As the use of electric vehicles become active, the demand of electric power for charging electric vehicles will increase. Therefore, it is important to predict accurately the electric demand for charging electric vehicles in order to establish a smooth demand supply plan. In this paper, electric vehicle charging station data from Seoul and Jeju Island were collected and the research was conducted to forecast the amount of charging power for each region. The time series prediction models (ARIMA, ARIMAX, ARIMA-GARCH, ARIMAX-GARCH, SARIMA, SARIMAX) for electric vehicles charging power amount prediction were compared on the basis of MAPE, SMAPE.
