Embodiment Construction

[0024] see figure 1 , figure 1 It is a schematic flow chart of an embodiment of the charging method of the present invention. The charging method of this embodiment is applied to a charging system. The charging system includes a charger, a data line and an electronic device. The data line connects the charger and the electronic device, and the charger charges the electronic device through the data line. The method specifically includes the following steps:

[0025] S101: When the charger charges the electronic device through the data line, the charger detects that the voltage at the connection between the electronic device and the data line is a first voltage.

[0026] see figure 2 , figure 2 yes figure 1 Example electronic equipment charging characteristic curve, from figure 2 It can be seen from the figure that the charging process of electronic equipment is divided into three stages: pre-charging stage, constant current charging stage and constant voltage charging ...

Abstract

The invention discloses a charging method, a charging system and electronic equipment. The method is applied to a charging system, and the charging system includes a charger, a data line and an electronic device. The method includes: when the charger charges the electronic device through the data line, the charger detects that the voltage at the connection between the electronic device and the data line is the first voltage; the charger obtains a first difference between the first voltage and a preset voltage value; the charger adjusts the first voltage according to the first difference, so that the adjusted first voltage is equal to the preset voltage value. In this way, the charging efficiency of the electronic device can be improved.

Description

technical field [0001] The invention relates to the technical field of charging, in particular to a charging method, a charging system and electronic equipment. Background technique [0002] With the continuous increase of power consumption of electronic equipment, the battery capacity is also increasing. For fast charging, the charging current is required to increase. The charging voltage becomes smaller, resulting in longer charging time and lower charging efficiency. [0003] The inventor of the present invention has found in the long-term research and development that in the current prior art, in order to improve the charging efficiency, the charging voltage can be controlled through the feedback of the output voltage of the charger terminal, and the detection point of the output voltage is usually set at the charger on the output port. This setting method does not have high control precision for the charging voltage, so that the charging efficiency cannot be effective...
