Abstract

There is provided a power information management device communicable with at least one another device and being able to perform one of mutual power supply and unidirectional power supply, comprising: a requesting unit configured to send a request for information concerning electric power to the at least one another device; a receiving unit configured to receive the power information from the at least one another device which has received the request; and a generating unit configured to generate power information concerning electric power of a plurality of devices including the power information management device and the at least one another device based on the information received from the at least one another device.

Claims

1. A power information management device communicable with at least one another device and being able to perform one of mutual power supply and unidirectional power supply, comprising:

a requesting unit configured to send a request for information concerning electric power to the at least one another device;

a receiving unit configured to receive the power information from the at least one another device which has received the request; and

a generating unit configured to generate power information concerning electric power of a plurality of devices including the power information management device and the at least one another device based on the information received from the at least one another device.

2. The power information management device according to claim 1,

wherein the power information concerning the plurality of devices includes at least one of:

a residual quantity of electric power of each device of the plurality of devices;

a first total residual quantity being a sum of residual quantities of electric power of each device of the plurality of devices;

a radio between a full charge capacity of one device of the plurality of devices and the first total residual quantity;

a second total residual quantity being a sum of residual quantities of electric power of the plurality of devices other than one device;

a ratio between a full charge capacity of one device of the plurality of devices and the second total residual quantity;

power consumption of each device of the plurality of devices;

a communication standard supported by each device of the plurality of devices;

information concerning power transmission efficiency between the plurality of devices;

information concerning power transmission rate between the plurality of devices; and

a number of cable connection terminals provided in each of the plurality of devices, the cable connection terminals being used to perform one of the mutual power supply and unidirectional power supply.

3. The power information management device according to claim 1,

further comprising a display unit configured to display the power information concerning electric power of the plurality of devices generated by the generating unit on a display screen.

4. The power information management device according to claim 1,

further comprising a communication unit configured to pair the power information management device with the at least one another device in accordance with a predetermined communication standard,

wherein the information concerning electric power is transmitted between the power information management device and the at least one another device in accordance with the predetermined communication standard.

5. The power information management device according to claim 1,

wherein the requesting unit is configured to send the request for the information concerning electric power to the at least one another device when a predetermined trigger condition is satisfied.

6. The power information management device according to claim 1,

further comprising a transmitting unit configured to transmit the power information concerning the plurality of devices generated by the generating unit to the at least one another device.

7. The power information management device according to claim 1,

wherein the power information management device performs one of the mutual power supply and unidirectional power supply with respect to the at least one another device via wired connection or wireless connection.

8. A power information management system, comprising:

a power information management device according to claim 1; and

at least one another device that transmits information concerning electric power in response to a request from the power information management device.
