ELECTRONIC APPARATUS, CHARGING CONTROL METHOD, CHARGING SYSTEM, AND DATA TRANSMISSION SYSTEM
First Claim
1. An electronic apparatus comprising:
- a battery;
a processing unit that executes an apparatus operation; and
a charging/discharging control unit that controls feeding to the processing unit and charging of the battery using external power and feeding from the battery to the processing unit,wherein the processing unit has a first operation mode in which the apparatus operation is executed using power equal to or less than the external power and a second operation mode in which the apparatus operation is executed using power more than the external power, an operation mode of the processing unit is switched into the first operation mode or the second operation mode according to the remaining capacity of the battery, and the apparatus operation is executed.

Abstract
Even in a state in which the remaining capacity of a battery decreases, an apparatus operation is appropriately executed while charging efficiency of the battery is maintained.
A processing unit 103 has a first operation mode in which an operation is enabled using only external power from a feeding device 120 and a second operation mode in which the operation is enabled by feeding from a battery 102 in addition to the external power from the feeding device 120. When the remaining capacity of the battery 102 is sufficient, the processing unit 103 executes an apparatus operation in the second operation mode. However, when the remaining capacity of the battery 102 decreases, the processing unit 103 changes an operation mode to the first operation mode and executes charging of the battery 102 while continuously executing the apparatus operation.
