ELECTRONIC DEVICE HAVING CHARGEABLE BATTERY, METHOD OF CHARGING, AND STORAGE MEDIUM

摘要

A CPU determines whether a specific operation is being performed in a system section. If the CPU determines that a specific operation is being performed, a USB charging control section temporarily stops charging of a battery, regulates the current supplied to the system section via a USB cable to be a prescribed constant current, and then supplies current lacking in the system section due to load variation from the battery.

主权项

1. An electronic device, comprising:
a battery that can be charged; a system section; and a charging control section connected to the system section and the battery, the charging control section being configured to receive external power from an external device via a cable, the charging control section allocating electrical current that is supplied from the external device to the system section for use thereby and the battery for charging, wherein the charging control section stops charging of the battery when the system section or the charging control section determines that a prescribed condition is met, wherein the charging control section regulates the electrical current supplied via the cable to be at a constant level while the charging of the battery is temporarily stopped, and wherein the charging control section supplies electrical current from the battery to the system section as needed to meet a power demand by the system section that is not met by the electric current via the cable, while the electrical current supplied via the cable is being regulated to be at the constant level.
