Power supply device, power receiving device and billing method
First Claim
1. A first device, comprising:
- a billing information generating unit configured to generate billing information for an amount related to electric power transmitted by the first device, wherein the first device is a power supply device;
a power line communication unit configured to communicate with a second device via a power line;
a billing processing unit configured to;
communicate with the second device to execute a billing process based on the communication via the power line and the billing information;
receive a response signal indicating a result of the billing process from the second device based on the communication, whereinthe response signal is transmitted by the second device by load modulation performed based on a first signal received from the first device; and
determine the result of the billing process based on the response signal; and
a power control unit configured to selectively transmit electric power to the second device based on the determined result.

Abstract
Devices, methods, and programs for billing for electric power. A billing method may include generating billing information for an amount related to electric power transmitted by a power supply device, performing a billing process based on the billing information, and selectively transmitting electric power based on the result of the billing process. A power supply device may include a billing information generating unit, a billing processing unit, and a power control unit. Another billing method may include determining whether billing information has been received, performing a billing process after it is determined that the billing information has been received, transmitting a response signal to a power supply device, and providing notice regarding information related to the billing process. A power receiving device may include a billing processing unit, a power control unit, and a notice control unit.

17. A power receiving device, comprising:
-
a power line communication unit configured to communicate with a power supply device via a power line; a billing processing unit configured to; determine that billing information is received, wherein the billing information is for an amount related to electric power received from the power supply device; execute a billing process based on the communication via the power line and the billing information; a power control unit configured to; transmit a response signal to the power supply device based on the billing process, wherein the response signal is transmitted by load modulation, and the load modulation is based on a signal received from the power supply device, and the response signal indicates a result of the billing process; control reception of the electric power from the power supply device based on the result of the billing process; and a notice control unit configured to generate notice information related to the billing process. - View Dependent Claims (18, 19, 20)
