[0103] Based on the first embodiment, if the charger connected to the fast charging device does not support the first charging protocol (Qualcomm QC4.0 fast charging protocol), then according to the preset priority order, first check whether the port type of the charger is preset The port type of the first priority (SDP port type). Specifically, the fast charging device pulls up the USB_DP to VDP_SRC level through the charger identification unit of the charging management module (releases the pull-up action on USB_DP after a certain period of time), and at the same time gives a weak pull-down to the USB_DN signal, and then compares the voltage of USB_DN and VDAT_REF When the level of USB_DN is lower than the level of VDAT_REF, it means that the port type of the charger is the SDP port type, and then the charging parameter corresponding to the SDP port type is configured by the CPU (defined as the second charging parameter), and the charging current Set to 0.5A (DCDC mode) to c...

Abstract

The invention discloses a charging method. The charging method is applied to a fast charging device. The charging method includes: after the fast charging device is connected to the charger, judging whether the charger supports the first charging protocol; if The charger does not support the first charging protocol, then detects the port types of the charger in sequence according to the preset priority order, and configures corresponding charging parameters according to the detected port types; to charge. The invention also discloses a fast charging device and a computer-readable storage medium. The invention is compatible with various chargers and realizes fast charging.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a charging method, a fast charging device and a computer-readable storage medium. Background technique [0002] With the development of science and technology, mobile terminal devices such as smartphones and tablet computers have been widely used in daily life. In order to improve the battery life of the mobile terminal, a mobile power supply for powering the mobile terminal has emerged. The latest Qualcomm QC4.0 fast charging protocol has been launched on the market, and the existing charging protocols include QC2.0, QC3.0 fast charging protocol, and USB PD protocol. The supported charging protocol must match the charging protocol supported by the mobile power supply to achieve fast charging, that is, fast charging cannot be achieved when the charger does not match the mobile power supply. Therefore, there is a mismatch between the charging protocol of the charger and the ch...
