Abstract

The embodiment of the present application discloses a charging method and device, a terminal, and a storage medium, wherein the method includes: when a communication port of a first charging device that is electrically connected to the terminal is short-circuited, controlling the first charging device charging the terminal with the first voltage; instructing the first charging device to disconnect the short circuit; when detecting that the short circuit is disconnected, instructing the first charging device to use the second voltage as the charging the terminal; wherein the second voltage is greater than the first voltage; after instructing the first charging device to charge the terminal with the second voltage, if it is detected that the electrical connection is not disconnected, Determine whether the first charging device supports outputting the second voltage; if not, control the first charging device to continue charging the terminal with the first voltage.

Description

technical field [0001] The embodiments of the present application relate to electronic technologies, and relate to, but are not limited to, charging methods and devices, terminals, and storage media. Background technique [0002] The development of Quick Charge (QC) technology has developed from QC1.0, QC2.0, QC3.0 to QC4.0. QC1.0 supports the adapter to output 4V2A power, that is, the output voltage of the adapter is 4V and the output current is 2A. On this basis, QC2.0 conducts communication negotiation through communication pins to support the adapter to output 5V2A, 9V2A and 12V1.5A power. At present, software solutions supporting QC technology are integrated on some terminals. [0003] However, for the compatibility of QC adapters, certain improvements must be made to the current software solutions supporting QC technology. This is because many third-party adapters are high-voltage and low-current charging methods, and most of these adapters are evolved on the basis ...
