Abstract
A power receiving device includes a connector configured to be connected to a power feeding device; a power source configured to receive a power supply from the power feeding device via the connector; and a controller configured to perform a predetermined process before a power supply stopping time in response to receiving a preliminary notification of power supply stopping from the power feeding device via the connector.
Claims20
A power receiving device comprising:
- a connector configured to be connected to a power feeding device;
- a power source configured to receive a power supply from the power feeding device via the connector;
- and
- a processor configured to perform a predetermined process before power supply stopping time in response to receiving a preliminary notification of power supply stopping from the power feeding device via the connector,
- wherein the preliminary notification of power supply stopping is different from the power supply received from the power feeding device.
A power feeding device comprising:
- one or more connectors configured to be connected to one or more power receiving devices;
- a power supplier configured to supply power to the one or more power receiving devices via the one or more connectors;
- a processor configured to:
- notify a predetermined power receiving device via the one or more connectors of a preliminary notification of power supply stopping generated based on a predetermined schedule;
- and
- stop supplying power from the power supplier to the predetermined power receiving device after a predetermined period of time has passed after notifying the predetermined power receiving device of the preliminary notification of power supply stopping.
A communication system comprising:
- one or more power receiving devices;
- and
- a power feeding device connected to the one or more power receiving devices,
- wherein,
- each of the one or more power receiving devices comprises:
- a first connector configured to be connected to the power feeding device;
- a power source configured to receive a power supply from the power feeding device via the first connector;
- and
- a first processor configured to perform a predetermined process before a power supply stopping time in response to receiving a preliminary notification of power supply stopping from the power feeding device via the first connector and,
- the power feeding device comprising:
- one or more second connectors configured to be connected to the one or more power receiving devices;
- a power supplier configured to supply power to the one or more power receiving devices via the one or more second connectors;
- a second processor configured to:
- notify a predetermined power receiving device via the one or more second connectors of the preliminary notification of power supply stopping generated based on a predetermined schedule;
- and
- stop supplying power from the power supplier to the predetermined power receiving device after a predetermined period of time has passed after notifying the predetermined power receiving device of the preliminary notification of power supply stopping.
A method executed by a power receiving device, the power receiving device comprising a connector configured to be connected to a power feeding device, a power source configured to receive a power supply from the power feeding device via the connector and a processor configured to receive a preliminary notification of power supply stopping from the power feeding device via the connector, the preliminary notification of power supply stopping being different from the power supply received from the power feeding device, the method comprising:
- performing a predetermined process before a power supply stopping time in response to the processor receiving the preliminary notification of power supply stopping.
A method executed by a power feeding device, the power feeding device comprising one or more connectors configured to be connected to one or more power receiving devices, and a power supplier configured to supply power to the one or more power receiving devices via the one or more connectors, the method comprising:
- notifying a predetermined power receiving device via the one or more connectors of a preliminary notification of power supply stopping generated based on a predetermined schedule;
- and
- stopping supplying power from the power supplier to the predetermined power receiving device after a predetermined period of time has passed after notifying the predetermined power receiving device of the preliminary notification of power supply stopping.
