Electronic device for controlling magnitude of charging current for charging to-be-charged electronic device

摘要

By controlling a charging current magnitude for charging a to-be-charged electronic device by a charging electronic device and current magnitudes of other loading elements of the charging electronic device, when the charging electronic device is switched to a fast charge mode or to an efficiency mode from a normal charge mode, a required current can be directly provided to the to-be-charged electronic device without raising a hardware cost for upgrading charging capabilities.

主权项

1. An electronic device configured to control a magnitude of a charge current for a to-be-charged electronic device, comprising:
a connection unit; a first loading unit; a control unit configured to control the electronic device to charge the to-be-charged electronic device under a first charge mode or a second charge mode; and a power supply unit coupled to the first loading unit, the control unit and the connection unit; wherein the power supply unit is configured to provide a first current to the to-be-charged electronic device via the connection unit and configured to provide a second current to the first loading unit when the electronic device is under the first charge mode; wherein the control unit is configured to adjust the second current to be a third current, and the power supply unit is configured to generate a fourth current according to both the second current and the third current so as to provide the fourth current to the to-be-charged electronic device when the electronic device is switched from the first charge mode to the second charge mode; and wherein the third current is smaller than the second current, and the fourth current is larger than the first current.
