Abstract

An electronic apparatus includes a power receiving unit configured to receive power, and a secondary battery configured to be charged on the basis of the power received by the power receiving unit. The electronic apparatus operates based on a discharge current of the secondary battery and is capable of communicating, to the outside, an instruction relating to a power transmission suspension time which is varied in accordance with an operation state of the electronic apparatus.

Claims

1. An electronic apparatus comprising:

a power receiving unit configured to receive power; and

a secondary battery configured to be charged on the basis of the power received by the power receiving unit,

wherein the electronic apparatus operates based on a discharge current of the secondary battery and is capable of communicating, to the outside, an instruction relating to a power transmission suspension time which is varied in accordance with an operation state of the electronic apparatus.

2. The electronic apparatus according to claim 1, further comprising:

a display unit capable of displaying a name of prescribed program being run,

wherein the suspension time is varied in accordance with the program being run.

3. The electronic apparatus according to claim 2, wherein the prescribed program includes a first program and a second program;

and

wherein a suspension time corresponding to the first program is set shorter than a suspension time corresponding to the second program if the first program consumes more power while being run than the second program.

4. The electronic apparatus according to claim 1, wherein the suspension time is varied in accordance with a power consumption.

5. The electronic apparatus according to claim 4, wherein the suspension time is shortened as the power consumption increases.

6. The electronic apparatus according to claim 4, further comprising:

a power consumption detection unit capable of detecting the current consumption.

7. The electronic apparatus according to claim 1, wherein the power receiving unit includes an electromagnetic coil.

8. The electronic apparatus according to claim 1, wherein the instruction relating to the suspension time is transmitted via the power receiving unit.

14. An electronic apparatus charging system comprising:

the electronic apparatus according to claim 1.

15. The electronic apparatus charging system of claim 14, further comprising the charger according to claim 9.

9. A charger comprising:

a power transmission unit configured to transmit power,

wherein the charger suspends or restarts power transmission according to an instruction relating to a power transmission suspension time which is communicated from the outside.

10. The charger according to claim 9, wherein the charger suspends the power transmission when receiving the instruction relating to the power transmission suspension time from the outside, and restarts the power transmission upon a lapse of the suspension time.

11. The charger according to claim 9, wherein the power transmission unit includes an electromagnetic coil.

12. The charger according to claim 9, wherein the instruction relating to the suspension time is received via the power transmission unit.

13. The charger according to claim 9, wherein the charger receives power from an external commercial power source.
