Embodiment Construction
[0049] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0050] The invention discloses a charging method. After an electronic device is connected to a charger, a corresponding charging process is started. When the charger fails to work normally, a preset anti-shake mechanism is adopted to maintain the charger's ability to charge the electronic device. process, so as to make the charging process stable, and solve the problem of repeated restarts or failure to charge during the charging process.

The invention provides a charging method and a charging device. The charging method comprises the following steps of: on the basis of the state that electronic equipment is connected with a charger, identifying the type of the charger; according to the type of the charger, starting the charging process corresponding to the type of the charger, so that the charger charges the electronic equipment by adopting a first current value; judging whether the charger can normally work or not in the charging process, so that a first judgement result is obtained; and, when the first judgement result shows that the charger cannot normally work, keeping the process of charging the electronic equipment by the charger by adopting a pre-set anti-shake mechanism. In the charging scheme in the invention, in a process that the electronic equipment is charged by the charger, if the charger cannot normally work, the pre-set anti-shake mechanism is adopted, so that the charging process is steady; and thus, the problem that restarting is repetitively carried out or charging cannot be carried out in the charging process can be solved.
Description
technical field [0001] The present invention relates to the field of electronic equipment, and more specifically relates to a charging method and a charging device. Background technique [0002] After years of development, the charger of terminal equipment generally adopts AC adapter (Alternating Current adapter, AC adapter, also called AC charger, or travel charger, or AC adapter), and has undergone various changes in output specifications. Different manufacturers have different product models, so that there are multiple connection adaptation possibilities between the mobile terminal device and the AC charger. [0003] And when the interface is unified, the user may connect a non-standard charger on the mobile terminal device. [0004] In the existing charging detection mechanism, when a low-power charger is connected to a terminal with high input power, it will continue to be in an OCP (Over Current Protect, over-current protection) state. That is: after connecting the d...
