Abstract

There is provided a power receiving device including a connecting unit that is connected to a power line through which power is transmitted, a determining unit that determines whether transmitted power is chargeable, based on power identification information indicating whether the transmitted power is chargeable power, and a notification control unit that performs notification based on a determination result.

Claims

1. A power receiving device, comprising:

one or more circuits configured to;

connect to a power line through which power is transmitted;

determine that the transmitted power is chargeable, based on power identification information which indicates that the transmitted power is chargeable power;

generate a notification based on a result of the determination;

communicate with an external connection device, that is connected by a wire with the power line, by a first load modulation based on a first signal that is transmitted from the external connection device,

wherein the power identification information is transmitted from the external connection device; and

block at least a second signal of a frequency of the transmitted power, and allow a high-frequency signal that has a frequency higher than the frequency of the transmitted power and is used for the communication.

2. The power receiving device according to claim 1,

wherein the one or more circuits are further configured to:

receive a carrier wave based on the high-frequency signal that is transmitted from the external connection device and has the frequency higher than the frequency of the transmitted power; and

communicate with the external connection device based on a second load modulation.

3. The power receiving device according to claim 1,

wherein the one or more circuits are further configured to determine that the transmitted power is chargeable based on the power identification information included in the transmitted power.

4. The power receiving device according to claim 1,

wherein the one or more circuits are further configured to generate one of a visual notification or an audio notification based on the result of the determination.

5. The power receiving device according to claim 1,

wherein the power receiving device is an electrical-power-driven vehicle.

6. A non-transitory computer-readable medium having stored thereon computer-readable instructions, which when executed by a computer, cause the computer to execute operations, the operations comprising:

determining that power transmitted through a power line is chargeable, based on power identification information indicating that the transmitted power is chargeable power;

generating a notification based on a result of the determination;

communicating with an external connection device, that is connected by a wire with the power line, by a load modulation based on a first signal that is transmitted from the external connection device,

wherein the power identification information is transmitted from the external connection device; and

blocking at least a second signal of a frequency of the transmitted power, and allowing a high-frequency signal that has a frequency higher than the frequency of the transmitted power and is used for the communication.
