A charging/discharging device includes an electricity storage unit provided in transport equipment, a power conversion unit for performing conversion of power exchanged between the electricity storage unit and an external power system, and a control unit for controlling an operation of the power conversion unit in accordance with a reception signal. A server device that manages charge/discharge of the electricity storage unit performs demand/supply prediction of power in the power system, decides a time, at which discharge of the electricity storage unit to the power system or charge of the electricity storage unit by power supplied from the power system is performed, and transmits an instruction including the decided time, at which the discharge or the charge is performed, to the charging/discharging device.

Server device

A charging/discharging device includes an electricity storage unit provided to a transport equipment, a power conversion unit that performs conversion of power exchanged between the electricity storage unit and an external power system, a reception unit that receives an instruction transmitted from a server device that decides a time at which discharge of the electricity storage unit to the power system or charge of the electricity storage unit by power supplied from the power system is performed, the instruction including the time at which the discharge or the charge is performed, and a control unit that starts up or stops based on the time indicated by the instruction received in the reception unit and controls an operation of the power conversion unit.

Charging/discharging device and charge/discharge control method for controlling charge or discharge of an electricity storage unit

A V2G system includes: a power system; a charging/discharging device including an electricity storage unit, a power conversion unit that converts power transferred between the electricity storage unit and the power system, a reception unit, and a control unit that controls an operation of the power conversion unit based on a received signal; and a server device that manages charging and discharging of the electricity storage unit. The server device determines a period of time during which power is discharged from the electricity storage unit to the power system or during which the electricity storage unit is charged using power supplied from the power system, and transmits an instruction including the period of time to the charging/discharging device. The control unit of the charging/discharging device starts up or stop based on the period of time indicated by the instruction from the server device.
