Abstract: A computer-based method is provided 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. Electric vehicles occupying the bays can provide temporary energy storage capacity to an energy grid. The forecasting method includes: forecasting future occupation of the bays by electric vehicles based on expected arrival times and expected stay durations; obtaining expected charge and discharge capabilities of the vehicles; forecasting a total state of charge and total energy storage capacity in the parking area; recording actual arrivals and departures; and adjusting the forecast of future occupation and the forecast of total state of charge and total energy storage capacity in the parking area.

Abstract: A collision avoidance method for a water-based vessel, including: obtaining real time data relating to the path of two or more vessels; identifying a collision risk between the two or more vessels; determining if the collision risk is above a predetermined threshold, wherein when the collision risk is above the predetermined threshold, determining one or more collision avoidance manoeuvres on the basis of historical navigational data which corresponds to the real-time data; providing the one or more collision avoidance manoeuvres to an operator of the one or more vessels.
