Abstract

A power control apparatus 10 to supply power, which can be packet transmitted/received, having predetermined identification information in a header part, to a plurality power consumption apparatuses 70 from outside includes (a) an identification information separation apparatus 20 for receiving the identification information and separating it, (b) a power reception propriety determination apparatus 30 for determining whether to receive the power based on the separated identification information, and (c) a power supply control apparatus 40 for controlling the power supply to the power consumption apparatus 70 connected to a power control apparatus based on the separated identification information.

First claim

The invention claimed is:

1. An electric mobile body comprising:
a power reception propriety determination unit configured to
transmit, to a power supply device, a request signal for requesting the power supply device to send information about power that the power supply device can supply,
receive the information about the power from the power supply device, wherein the information indicates whether the power supply device supplies the power from a single power supply generator or from at least two or more power supply generators,
determine, based on the received information about the power, whether the power can be received, and
transmits, to the power supply device, a power supply request signal for requesting a supplying of power when the power is determined to be receivable, and

a power reception unit configured to receive the power from the power supply device,
wherein the power reception property determination unit and the power reception unit are each implemented via at least one processor.

2. The electric mobile body according to claim 1 , wherein
the power supply request signal includes information about a power supply method.

3. The electric mobile body according to claim 1 , wherein
the information about the power includes information indicating whether the power is renewable energy.

4. The electric mobile body according to claim 1 , wherein
the information about the power includes information to identify power based on solar power generation, power based on solar thermal power generation, power based on wind power generation, power based on geothermal power generation, power based on biomass power generation, power based on power generation by ocean thermal energy conversion, power based on thermal power generation, power based on hydropower generation, power based on nuclear power generation, and power based on other power generation.

5. The electric mobile body according to claim 1 , wherein
the information about the power is transported by the power.

6. The electric mobile body according to claim 1 , further comprising:
a communication apparatus, wherein
the request signal and the information about the power are transmitted/received via the communication apparatus.

7. The electrical mobile body according to claim 1 , wherein the power reception propriety determination unit is further configured to determine that the power cannot be received based on the received information about the power.

8. The electrical mobile body according to claim 3 , wherein the power reception propriety determination unit is further configured to reject the power when the received information about the power indicates the power is not associated with renewable energy.

9. The electrical mobile body according to claim 1 , wherein the information about the power further includes information of a power transmission source.

10. The electrical mobile body according to claim 1 , wherein the information about the power further includes information of carbon dioxide emissions per power generation unit time.

11. The electrical mobile body according to claim 1 , wherein the information about the power further includes a flag for distinguishing commercial or private owner.

12. A power receiving method for an electric mobile body, the method being executed via at least one processor, and the method comprising:
transmitting, to a power supply device, a request signal for requesting the power supply device to send information about power that the power supply device can supply;
receiving the information about the power from the power supply device;
determining whether the power can be received based on the received information about the power;
transmitting, to the power supply device, a power supply request signal for requesting a supplying of power when the power is determined to be receivable; and
receiving the power from the power supply device,
wherein the information about the power indicates whether the power supply device supplies the power from a single power supply generator or from at least two or more power supply generators.
