Server, power management system, and power management method
A green zone exists in which traveling of a vehicle using an amount of electric power that has a greenhouse gas emission intensity greater than a regulatory limit is restricted. A server includes. I/O ports through which the emission intensity of the electric power supplied from an electric vehicle supply equipment is obtained; and a processor that associates the amount of electric power charged from the electric vehicle supply equipment to a battery with the emission intensity obtained through the I/O ports. The processor: determines, based on an amount of electric power having an emission intensity less than the regulatory limit within the amount of electric power stored in the battery, whether a vehicle should be permitted to travel in the green zone; and notifies a user of the vehicle of a determination result.
1. A server for managing electric power information of a vehicle, wherein
the vehicle includes a power storage device that is charged with electric power supplied from a charging facility,
the server comprising:
an interface that obtains an emission intensity of greenhouse gas of electric power supplied from the charging facility; and
a processor that associates an amount of electric power charged from the charging facility to the power storage device with the emission intensity obtained via the interface, wherein
the processor:
determines, based on an amount of electric power having the emission intensity less than a regulatory limit within an amount of electric power stored in the power storage device, whether to permit the vehicle to travel within a travel restriction zone in which traveling using an amount of electric power having the emission intensity greater than the regulatory limit is restricted; and
notifies a user of the vehicle of a determination result.
2. The server according to claim 1 , wherein
the processor:
notifies the user of the vehicle as being permitted to travel in the travel restriction zone, when the amount of electric power having the emission intensity less than the regulatory limit is greater than a reference amount; and
notifies the user of the vehicle as being not permitted to travel in the travel restriction zone, when the amount of electric power having the emission intensity less than the regulatory limit is less than the reference amount.
3. The server according to claim 1 , wherein
prior to the vehicle entering the travel restriction zone, the processor notifies the user of the determination result.
4. A power management system, comprising:
the server according to claim 1 ; and
the vehicle, wherein
the vehicle includes a display, and
the display shows the determination result in a manner viewable from inside the vehicle.
5. The power management system according to claim 4 , wherein
the display further shows at least one of the amount of electric power having the emission intensity less than the regulatory limit and a distance that the vehicle is allowed to travel using the amount of electric power.
6. A power management system, comprising:
the server according to claim 1 ; and
the vehicle, wherein
the vehicle includes a display, and
the display shows the determination result in a manner viewable from outside the vehicle.
7. The power management system according to claim 4 , further comprising
a gate disposed at a boundary of the travel restriction zone, wherein
as the vehicle approaches the gate, the gate opens or closes depending on the amount of electric power having the emission intensity less than the regulatory limit.
8. A method for managing electric power information of a vehicle, wherein
the vehicle includes a power storage device that is charged with electric power supplied from a charging facility,
the method comprising:
obtaining the amount of electric power charged from the charging facility to the power storage device,
obtaining an emission intensity of greenhouse gas of the electric power supplied from the charging facility;
associating the amount of electric power charged from the charging facility to the power storage device with the emission intensity;
determining, based on an amount of electric power having the emission intensity less than a regulatory limit within an amount of electric power stored in the power storage device, whether to permit the vehicle to travel within a travel restriction zone in which traveling using an amount of electric power having the emission intensity greater than the regulatory limit is restricted; and
notifying a user of the vehicle of a determination result.
