Embodiment Construction
[0044] The technical solutions in the embodiments of the present invention will be described in detail below with reference to the accompanying drawings of the present invention.
[0045] During the process of filing this application, the inventor of the present application found that the charging of terminal equipment is usually divided into four stages, namely trickle-charge, pre-charge, constant-current charge, CC), constant-voltage charge (CV). Among them, the constant current charging CC is one of the stages that mainly affects the charging speed. Usually, designers hope that the terminal equipment stays in the CC stage for a long enough time and the current is large enough, so that the charging time will be reduced accordingly.
[0046] like figure 1 In the existing terminal equipment charging solution, when the charger is inserted for charging, the charging chip can convert the input power supply voltage into the charging voltage Vsys, and then convert and output the c...

The embodiment of the present invention discloses a charging control method, related equipment, and a computer storage medium, wherein the terminal equipment includes a charging chip, a processor, and a battery, and the charging chip is used to convert the power supply voltage into a battery voltage to charge the battery Charging, wherein the power supply voltage is greater than the limited power supply voltage, and the battery voltage is lower than the limited battery voltage; the processor is configured to simultaneously increase the limited power supply voltage and the limited battery voltage when the first condition is met or increase the limited battery voltage and decrease the charging current at the same time; if the second condition is met, decrease the limited power supply voltage and the limited battery voltage at the same time, or simultaneously increase the limited battery voltage The limit battery voltage decreases and the charging current increases. By adopting the embodiment of the present invention, the charging time can be shortened on the premise of ensuring charging safety.
Description
technical field [0001] The present invention relates to the technical field of electronic circuits, and in particular, to a charging control method, related equipment and a computer storage medium. Background technique [0002] With the continuous development of technologies such as LCD screens and dual cameras, the power consumption of terminal devices is increasing. When the battery capacity of the device is certain, the charging speed is particularly important, and even directly affects the user's choice of device products. [0003] like figure 1 A schematic structural diagram of a battery charging circuit is shown. like figure 1 , the charger (also referred to as an adapter, adapter) is connected to the USB port of the terminal device through a universal serial bus (universal serial bus, USB), and is converted into a charging voltage Vsys through a charging chip (charger). The charging voltage can not only charge the battery, but also supply power to the system load....
