Energy management system and energy management method

An energy management system for managing charging/discharging of a storage battery of a vehicle equipped with the storage battery, comprising:

• one or more processor to execute a program;
• and
• one or more memory to store the program which, when it is executed by the processor, causes the processor to perform processes comprising:
• managing a schedule for the vehicle to move from a first facility being a facility at which the storage battery is chargeable/dischargeable, to a second facility being a facility at which the storage battery is chargeable/dischargeable;
• and
• creating a first charging/discharging plan being a charging/discharging plan for the storage battery at each of the first facility and the second facility, wherein
• the creating the first charging/discharging plan creates the first charging/discharging plan with which the storage battery discharges at the first facility while leaving moving power being power for the vehicle to move from the first facility to the second facility, and
• the managing the schedule manages a planned arrival time being a time at which the vehicle is planned to arrive at the first facility and the second facility, respectively, and a planned departure time being a time at which the vehicle is planned to depart from the first facility and the second facility, respectively,
• the processes further comprising:
• changing at least one of the planned arrival time and the planned departure time, wherein
• the changing at least one of the planned arrival time and the planned departure time creates a second charging/discharging plan with which a value obtained by subtracting a total discharging profit generated by a discharge of the storage battery at the first facility and the second facility from a total charging cost generated by a charge of the storage battery at the first facility and the second facility is minimized based on the at least one of the planned arrival time and the planned departure time that have been changed,
• the processes further comprising:
• calculating total power costs for the created first charging/discharging plan and the created second charging/discharging plan, respectively;
• presenting the schedule corresponding to the second charging/discharging plan under a condition where the total power cost for the second charging/discharging plan is lower than the total power cost for the first charging/discharging plan;
• and
• electronically notifying the created first charging/discharging plan or the created second charging/discharging plan to a dedicated controllable application to charge/discharge the storage battery of the vehicle according to the created first charging/discharging plan depending upon whether the condition where the total power cost for the second charging/discharging plan is lower than the total power cost for the first charging/discharging plan.

• and
• creating a first charging/discharging plan being a charging/discharging plan for the storage battery in each of the first facility and the second facility, wherein
• the creating the first charging/discharging plan creates the first charging/discharging plan with which the storage battery discharges at the first facility while leaving moving power being power for the vehicle to move from the first facility to the second facility,
• the processes further comprising:
• managing vehicle information being information including a storage capacity of the storage battery, a chargeable/dischargeable capacity of the storage battery, and charging/discharging efficiency of the storage battery;
• and
• electronically notifying the created first charging/discharging plan to a dedicated controllable application to charge/discharge the storage battery of the vehicle according to the created first charging/discharging plan, wherein
• the creating the first charging/discharging plan creates the first charging/discharging plan with which a value obtained by subtracting a total discharging profit generated by a discharge of the storage battery at the first facility and the second facility from a total charging cost generated by a charge of the storage battery at the first facility and the second facility is minimized, based on the vehicle information.

An energy management method of managing charging/discharging of a storage battery of a vehicle equipped with the storage battery, the energy management method comprising:

• managing a schedule for the vehicle to move from a first facility being a facility at which the storage battery is chargeable/dischargeable, to a second facility being a facility at which the storage battery is chargeable/dischargeable;
• creating a first charging/discharging plan being a charging/discharging plan for the storage battery in each of the first facility and the second facility, the creating the first charging/discharging plan is such that the storage battery discharges at the first facility while leaving moving power being power for the vehicle to move from the first facility to the second facility;
• managing power unit price information being information including a power unit price at each time of the first facility and the second facility;
• and
• electronically notifying the created first charging/discharging plan to a dedicated controllable application to charge/discharge the storage battery of the vehicle according to the created first charging/discharging plan, wherein
• the creating the first charging/discharging plan creates the first charging/discharging plan with which a value obtained by subtracting a total discharging profit generated by a discharge of the storage battery at the first facility and the second facility from a total charging cost generated by a charge of the storage battery at the first facility and the second facility is minimized, based on the power unit price information.
