ELECTRONIC DEVICE AND ELECTRONIC DEVICE CHARGING SYSTEM

摘要

An electronic device includes a power receiving unit and a secondary battery. The electronic device can send an instruction to an outside to stop power transmission, and operates by a discharge current of the secondary battery. In a case where the secondary battery is charged and a voltage of the secondary battery becomes higher than a first threshold and lower than a second threshold larger than the first threshold, charging of the secondary battery is stopped without sending the instruction to stop the power transmission, and after an elapse of a predetermined period of time, the charging of the secondary battery is restarted. When the voltage of the secondary battery thereafter becomes higher than the second threshold, the instruction to stop the power transmission is sent, and the charging of the secondary battery is stopped.

主权项

1. An electronic device comprising:
a power receiving unit which receives electric power; and a secondary battery which is to be charged based on the electric power received by the power receiving unit, wherein said electronic device is capable of sending an instruction to an outside to stop power transmission, and operates by a discharge current of the secondary battery, wherein in a case where the secondary battery is charged and a voltage of the secondary battery becomes higher than a first threshold and lower than a second threshold which is larger than the first threshold, charging of the secondary battery is stopped without sending the instruction to stop the power transmission, and after an elapse of a predetermined period of time, the charging of the secondary battery is restarted, and wherein when the of the secondary battery thereafter becomes higher than the second threshold, the instruction to stop the power transmission is sent, and the charging of the secondary battery is stopped.
