  • Publication number: 20160343011
    Abstract: This electricity-demand prediction device is provided with a data reception unit, an individual-model generation unit, and a demand-prediction computation unit. Vehicle probe data in which specific driving states are recorded is inputted to the data reception unit, and on the basis of said vehicle probe data, the individual-model generation unit generates an individual model for each specific vehicle or for each user of a specific vehicle. Said individual models represent correlations between historical values associated with factor information regarding factors in decisions to charge specific vehicles at a specific charging facility and historical values representing electricity demand for said specific vehicles at said specific charging facility. The demand-prediction computation unit computes a predicted electricity demand for the specific vehicles at the specific charging facility on the basis of the generated individual models.
