Double-charging control circuit and double-charging control method

Abstract

The invention relates to the technical field of charging control, and provides a double-charging control circuit and a double-charging control method. The circuit comprises a power adapter charging circuit and a type-c adapter charging circuit. When the power adapter charging circuit or type-c adapter charging circuit is independently connected into a corresponding adapter, power is supplied to amainboard system and a battery. When the power adapter charging circuit and the type-c adapter charging circuit are connected into adapters at the same time, the power adapter charging circuit supplies power to the mainboard system, and the type-c adapter charging circuit charges the battery. According to the embodiment of the invention, when a computer system is in heavy load operation, the powerutilization requirement of a system can be met, the battery can be charged, the problem that the current generates a current loop between the two adapters due to inconsistent output voltages of the adapters does not exist, and the problem that the computer battery cannot be charged due to insufficient power consumption of the adapters can be effectively solved.

Description

technical field [0001] The present application relates to the technical field of charging management, and in particular, to a dual charging control circuit and a dual charging control method. Background technique [0002] With the continuous improvement of computer configuration, the power consumption of the motherboard system is also increasing. Since the power adapter of the computer has a rated working wattage, when the computer load is not large, the power adapter can meet the normal operation of the system equipment, and can also have some power to charge the battery; but when the computer CPU or GPU is overloaded, the system works. When the power consumption reaches a certain amount, the battery management chip will stop the power adapter from charging the battery, and even need the battery auxiliary power adapter to supply power. Although this solves the problem of computer applications, it will make the battery charging efficiency extremely low, and the battery will ...

AI Technical Summary

Problems solved by technology

Since the power adapter of the computer has a rated working wattage, when the computer load is not heavy, the power adapter can meet the normal work of the system equipment and can also charge the battery with some power; but when the computer CPU or GPU is overloaded, the system will not work properly. When the power consumption reaches a certain level, the battery management chip will terminate the power adapter to charge the battery, and even need the battery to assist the power adapter to supply power. Although this solves the problem of computer applications, it will make the charging efficiency of the battery extremely low. The power supply time of the battery is reduced during power supply, which cannot meet the needs of users
