Embodiment Construction

[0018] see figure 1 , which is a flow chart of the steps of the system power monitoring method of the present invention. In the figure, the flowchart starts with system power monitoring.

[0019] Step S11: judging whether the battery stops charging or whether the battery capacity is higher than the preset battery capacity. If yes, control the system power according to the preset power value and return to system power monitoring to continue judging; if not, proceed to the next step S12.

[0020] Step S12: Determine whether the charging current value is less than a preset current value. If yes, go to the next step S13; if not, go to step S13a.

[0021] Step S13: Determine whether the system power value is less than a preset power value. If yes, proceed to the next step S14; if not, control the system power according to the preset power value and return to system power monitoring to continue to judge.

[0022] Step S14: Decrease the preset power value, then control the syste...

Abstract

The invention discloses a system and a method for monitoring system power supply. The method for monitoring the system power supply is suitable for an electronic device, and comprises the following steps: firstly, obtaining a charging material from a charging module; secondly, judging whether the charging module stops charging a battery or a battery capacity is higher than a preset battery capacity according to the charging material; if the charging module charges the battery, and the battery capacity is lower than the preset battery capacity, judging whether a charging current value of the battery is smaller than a preset current value; if the charging current value of the battery is smaller than the preset current value, and a system power value is smaller than a preset power value, controlling an element to reduce the preset power value; and if the charging current value is greater than the preset current value, and the system power value is greater than the preset power value, controlling the element to increase the preset power value so as to further correctly adjust the power of the electronic device.

Description

technical field [0001] The invention relates to a system power monitoring device and a method thereof, in particular to a system power monitoring device and a method for judging battery charging status to adjust a system power default value. Background technique [0002] With the development of electronic technology, the size of many electronic systems, such as notebook computers, is getting smaller and smaller, and the amount of signals they need to process is also becoming more and more complicated. A large number of program calculations cause the electronic system to use too much power. Excessive power will reduce the service life of the components of the electronic system, and even cause damage to the electronic system. Therefore, electronic systems need a power management system to effectively manage power. Taking a notebook computer as an example, traditionally, the power management system uses resistance to measure the current and voltage of the power supply to know...
