In the related art, referring to fig. 8, the notebook computer includes a Charger plug-in detection circuit, a charging integrated circuit (Charger IC)100, an Embedded Controller (EC) 300, a Fuel Gauge IC 700, a Voltage Regulator (Voltage Regulator, VR), and a first switch circuit SW 1. When the notebook computer is in a standby or shutdown working state, the scheme for realizing energy saving in the related technology mainly comprises the following steps: detecting the insertion of the charger by a charger detection circuit and outputting a charger insertion signal; after the embedded controller 300 receives the charger insertion signal, the charging integrated circuit 100 detects whether the charging input voltage meets the standard; when the voltage input from the electrical appliance meets the standard, the embedded controller 300 controls the charging integrated circuit 100 to be powered on continuously, and the charging integrated circuit 100 charges the battery 200; when the fuel gauge circuit 700 detects that the battery 200 is fully charged, the embedded controller 300 sends a charging stop control signal, and the charging integrated circuit 100 stops continuing to charge the battery 200 after receiving the charging stop control signal, so that overcharging is prevented, and power consumption is reduced. However, the charging integrated circuit 100 is in a power-on state, and other modules are also consuming energy. The related art generally uses the first switch circuit SW1 to control whether the charging integrated circuit 100 can receive the charging input voltage, the first switch circuit SW1 is only illustrated in fig. 8, and the related art first switch circuit SW1 generally uses a fet switch circuit and is controlled to be turned on or off by the embedded controller 300. It should be noted that, in the related art, the voltage regulator includes a voltage conversion module, the power amount of the battery 200 is monitored by the fuel gauge circuit 700, the fuel gauge circuit 700 outputs the monitored power amount information of the battery 200 to the embedded controller 300, and the embedded controller 300 controls other related circuits and modules according to the power amount information.
It can be appreciated that when a charger is plugged into a laptop computer, the charger has a charging input voltage.
It should be noted that fig. 8 to 10 are used for illustrating and explaining the technical solution of the present invention, and only show the components and modules and the corresponding connection relationships that have a great influence on understanding the technical solution of the present invention, and hide other components, modules and connection relationships, but this will not affect those skilled in the relevant art to further understand the technical solution of the present invention by referring to fig. 8 to 10.
The technical solution disclosed in the present invention is an improvement of an energy saving solution of the related art, and referring to fig. 1 and fig. 8, an embodiment of a first aspect of the present invention provides an energy saving control method, which is applied to an embedded controller 300 of a notebook computer, where the notebook computer includes a battery 200 and a charging integrated circuit 100, and the method includes, but is not limited to:
and step S100, detecting the insertion of a charger and obtaining a charging input voltage.
In the related art, the control module is generally an embedded controller 300, and the embedded controller 300 initializes related circuits and modules and detects the charging input voltage through the corresponding modules.
And step S200, controlling the charging integrated circuit to be electrified continuously and controlling the charging integrated circuit to charge the battery according to the charging input voltage.
It can be understood that, in daily use, there are occasions when the notebook computer is plugged with the charger for a long time but is not in an active state, when the battery 200 is fully charged and the working state of the notebook computer is standby or shutdown, the charging integrated circuit 100 does not need to charge the battery 200, and the charging integrated circuit 100 consumes more electric energy in a non-charging state, thereby causing waste, at this time, the power supply to the charging integrated circuit 100 can be directly cut off, thereby when the charging integrated circuit 100 is stopped charging the battery 200, the consumption of the input electric quantity of the charger when the charging integrated circuit 100 is not charged can be further avoided. The on-off control of the charging integrated circuit 100 may be implemented by a switching circuit, which is connected in series between the charging integrated circuit 100 and the charging input terminal, and when the battery 200 is fully charged and the notebook computer is in a standby state or a shutdown state, the switch prevents the electric energy from flowing into the charging integrated circuit 100, and the switching circuit may be implemented by a fet or a triode switching circuit.
The technical solution of the first aspect of the present invention at least has the following beneficial effects: in the related art, when the notebook computer is in a standby state or a shutdown state, and the charger is always in the plugged-in state, and the battery 200 is fully charged, the charging ic 100 stops charging the battery 200 by sending a command related to stopping charging, but the charging ic 100 itself is still in a power-on state, thereby causing energy consumption. By directly stopping the power supply of the charging integrated circuit 100, the charging integrated circuit 100 stops working while the battery 200 stops charging, thereby reducing the maintenance power consumption of the notebook computer in a standby or shutdown state, the charger in a plug-in state all the time, and the battery 200 in a full state to the maximum extent.
Referring to fig. 2 and 8, it can be understood that, in step S200, according to the charging input voltage, the charging integrated circuit is controlled to be continuously powered on and controlled to charge the battery, including but not limited to the following steps:
step S210, generating a continuous charging signal according to the charging input voltage by the charging integrated circuit.
It is understood that when a charger is plugged in and detected, the embedded controller 300 will energize the charging integrated circuit 100 by sending an energizing signal, the energized integrated circuit will detect whether the charging input voltage meets the charging standard, and when the charging input voltage of the charger does not meet the charging standard, the embedded controller 300 will stop sending the energizing signal, so that the charging integrated circuit 100 stops energizing and the battery 200 will not be charged. The charging integrated circuit 100 detects that the charging input voltage meets the charging standard and generates a continuous charging signal.
And step S220, generating a charging parameter signal according to the continuous charging signal, and continuously outputting a continuous electrifying signal to control the charging integrated circuit to be electrified continuously.
It can be understood that, when receiving the continuous charging signal, the corresponding port of the embedded controller 300 will continuously output the continuous power-on signal, i.e. keep the relevant port always at the high level, which may be used to control the relevant switch circuit, and when at the high level, it is turned on, so that the charging integrated circuit 100 is continuously in the power-on state. The embedded controller 300 generates a charging parameter signal to the charging integrated circuit 100 to control the charging parameters of the charging integrated circuit 100.
And step S230, charging the battery through the charging integrated circuit according to the charging parameter signal.
Referring to fig. 3, it can be understood that, in step S300, when the battery is fully charged and the working state of the notebook computer is standby or shutdown, the charging integrated circuit is controlled to stop powering on, including but not limited to the following steps:
step S310, it is detected that the battery is fully charged and the working state of the notebook computer is standby or shutdown.
And step S320, stopping outputting the continuous power-on signal to control the charging integrated circuit to stop power-on.
Referring to fig. 4, in some embodiments of the invention, the energy saving control method further includes, but is not limited to, the following steps:
and S400, when the electric quantity of the battery is reduced to a preset value, controlling the charging integrated circuit to be powered on continuously and controlling the charging integrated circuit to charge the battery.
Referring to fig. 5, it can be understood that, in step S400, when the battery level drops to a preset value, the charging integrated circuit is controlled to be powered on continuously and controlled to charge the battery, including but not limited to the following steps:
and step S410, detecting that the battery power is reduced to a preset value.
Step S420, continuously outputting a continuous power-on signal to control the charging integrated circuit to be continuously powered on, and outputting a charging parameter signal.
And step S430, charging the battery through the charging integrated circuit according to the charging parameter signal until the battery is fully charged.
It is understood that the preset value for the power reduction of the battery 200 may be about 95% of the total power in the related art, and the difference from the total power is set to avoid frequent power on/off of the charging integrated circuit 100. In the related art, the amount of power of the battery 200 is monitored by the fuel gauge circuit 700 and related information is transmitted to the embedded controller 300. When the power of the battery 200 drops to a predetermined value, the embedded controller 300 continuously sends a continuous power-on signal to power on the charging integrated circuit 100, and the embedded controller 300 inputs the charging parameter signal to the charging integrated circuit 100 to charge the battery 200 according to the charging parameter signal until the battery is fully charged. When the battery 200 is fully charged, the notebook computer is in a standby or shutdown state, and the charger is always in an inserted state, the embedded controller 300 stops sending the continuous power-on signal to stop the power-on of the charging integrated circuit 100.
Referring to fig. 6 to 9, the notebook computer further includes a voltage conversion module; the energy-saving control method of the notebook computer further comprises the following steps of but not limited to:
and S500, when the battery is fully charged and the working state of the notebook computer is shutdown, controlling the voltage conversion module to stop working.
It can be understood that the voltage conversion module refers to a module for outputting a corresponding voltage to supply power to the hardware of the notebook computer, such as the memory and the hard disk. In some related technologies, some voltage conversion modules are also in an active state in a shutdown state, and the corresponding load 800 does not operate, so that the voltage conversion modules also increase the sustain power consumption. Stopping the operation of these voltage conversion modules further reduces the maintenance power consumption. In the related art, the voltage conversion module is provided with an enable terminal, and when the enable terminal is at a low level, the voltage conversion module stops working.
Referring to fig. 7 to 9, according to some embodiments of the present invention, the notebook computer further includes a platform controller center 400, and the voltage conversion module includes a 1.8V voltage module 500 and a 5V voltage module 600; in step S500, when the battery is fully charged and the working state of the notebook computer is off, the voltage conversion module is controlled to stop working, including but not limited to the following steps:
step S510, it is detected that the battery is fully charged and the working state of the notebook computer is shutdown.
And step S520, stopping outputting the power supply indication signal to the platform controller center.
And step S530, stopping outputting the enable signals to the 1.8V voltage module and the 5V voltage module through the platform controller center.
And step S540, controlling the 1.8V voltage module and the 5V voltage module to stop working.
The platform controller center 400 is configured to output an enable signal according to the power indication signal, the 1.8V voltage module 500 is configured to output a first voltage according to the enable signal, and the 5V voltage module 600 is configured to output a second voltage according to the enable signal.
It is understood that, referring to fig. 8, in the related art, a Platform Controller Hub (PCH) 400 is usually disposed in the notebook computer, and the embedded Controller 300 outputs a power supply indication signal to the PCH 400, that is, a corresponding port of the embedded Controller 300 continuously outputs a high level; when the platform controller center 400 receives the power supply indication signal, it will continuously output a high level, i.e., an enable signal, to the enable terminals of the 1.8V voltage module 500 and the 5V voltage module 600; the 1.8V voltage module 500 and the 5V voltage module 600 work after receiving the enable signal, and correspondingly output a 1.8V voltage and a 5V voltage. When the power supply indication signal is stopped, that is, when the corresponding port of the embedded controller 300 outputs a low level, the platform controller center 400 stops inputting the enable signal, and thus the 1.8V voltage module 500 and the 5V voltage module 600 stop operating, thereby reducing the sustain power consumption. When the notebook computer is in a shutdown state, the charger is always inserted, and the battery 200 is fully charged, the 1.8V voltage module 500 and the 5V voltage module 600 consume the electric energy of the battery 200, which may cause the electric quantity of the battery 200 to be rapidly reduced to a preset value, so that the charging integrated circuit 100 is frequently powered on and powered off, and the 1.8V voltage module 500 and the 5V voltage module 600 are turned off, thereby preventing the electric quantity of the battery 200 from being consumed too rapidly, and further reducing the maintenance power consumption.
It should be noted that when a charging input voltage is input, the embedded controller 300 needs to initialize the modules and circuits of the platform controller center 400, the 1.8V voltage module 500, the 5V voltage module 600, and the like, and then perform the charging step after the initialization is completed, so that the charging process can be performed normally. In the shutdown state, the initialization step needs to be executed, so that the modules and circuits such as the 1.8V voltage module 500 and the 5V voltage module 600 are also started, and the 1.8V voltage module 500 and the 5V voltage module 600 stop working after the battery 200 is fully charged, so that the influence on the initialization process can be avoided, and the effect of reducing and maintaining power consumption is achieved.

The second switch circuit SW2 may be formed by a fet or a triode switch circuit. When the 1.8V voltage module 500 and the 5V voltage module 600 need to stop working, the embedded controller 300 controls the second switch circuit SW2 to be turned on, so that the enable terminals of the 1.8V voltage module 500 and the 5V voltage module 600 are grounded, thereby stopping working.

IN another embodiment of the present invention, when the charging input voltage is input and the battery is fully charged and the notebook computer is IN the shutdown state, the embedded controller may control the third switch circuit SW3 to disconnect the charging input terminal V _ IN and the power supply input terminal, so as to cut off the power supply path of the charging input voltage to the platform controller center 400, so that the embedded controller 300 controls the platform controller center 400 to stop working, thereby further reducing the power consumption. It is understood that the third switching circuit SW3 may be formed of a fet or a triode switching circuit.
