Forecast of electric vehicle state of charge and energy storage capacity

A computer-based method of forecasting total electric vehicle state of charge and total electric vehicle energy storage capacity in a parking area having parking bays with respective electrical vehicle charging and discharging facilities, whereby electric vehicles occupying the parking bays can provide temporary energy storage capacity to an energy grid, the forecasting method including steps of:

• forecasting future occupation of the parking bays by electric vehicles based on expected arrival times and expected stay durations of electric vehicles entering the parking area;
• obtaining expected charge and discharge capabilities of the electric vehicles forecast to enter the parking area;
• forecasting, on the basis of the forecast of future occupation and the expected charge and discharge capabilities, a total electric vehicle state of charge and total electric vehicle energy storage capacity in the parking area;
• recording actual arrivals and departures of electric vehicles at the parking area;
• and
• adjusting, on the basis of the recorded arrivals and departures, the forecast of future occupation and the forecast of total electric vehicle state of charge and total electric vehicle energy storage capacity in the parking area.
