Abstract
本申请提供一种充电电流控制方法、电子设备和电源提供装置，包括：在为所述电池充电的过程中，所述电子设备确定目标阻抗，所述目标阻抗包括第一阻抗和第二阻抗，所述第一阻抗为所述电源提供装置的输出端和所述主板的输入端之间的阻抗，所述第二阻抗为所述主板的输出端与所述电池的输入端之间的阻抗，所述目标阻抗小于所述电源提供装置的输出端和所述电池的输入端之间的总阻抗；所述电子设备向所述电源提供装置发送指示信息，所述指示信息指示所述电源提供装置根据所述目标阻抗调整所述电源提供装置的输出电流。由于所确定的目标阻抗不包括主板的阻抗或包括主板的部分阻抗，因此能够避免因为主板的阻抗增加而调整快充电流或退出快速充电模式。
