wc (wake-up charge): and the awakening charging mode is responsible for initializing battery charging, initializing communication (SMBUS) between the battery and the ec, reading the residual electric quantity of the battery and judging whether the battery is overdischarged or not or whether the battery can be charged or not.
Pc (pre-charge): the pre-charging mode, which is generally a low current charging mode, is performed for about 6 seconds, and the low current charging mode is generally 0.2A, and then the pre-charging mode is converted into a normal charging (nc) mode.
Nc (normal charge): normal charging, after the precharge is completed, normal charging is performed, and the charging current is generally limited to about 2A.
Dc (discharge): the charging is stopped.
Fc (full charged): and when the battery is fully charged, the communication between the ec and the battery is utilized to obtain the information of the residual electric quantity of the battery, so as to avoid the influence on the service life of the battery due to the overcharge of the battery, and when the electric quantity of the battery is greater than 98% or the electric quantity is greater than 95%, and the charging current is less than 100mA, the battery can be considered to be fully charged.
The voltage of the high-capacity notebook lithium battery can reach 16.8v, and the charging power consumption is about 30w when the high-capacity notebook lithium battery is charged at full current.
FIG. 1 is a schematic flow diagram of a method of one embodiment of the invention. The execution main body in fig. 1 may be a power consumption control system of a notebook computer.
As shown in fig. 1, the method includes:
In order to facilitate understanding of the present invention, the power consumption control method of the notebook computer according to the present invention is further described below with reference to the principle of the power consumption control method of the notebook computer according to the present invention and the process of controlling the power consumption of the notebook computer in the embodiment.
The method provided by the invention can be operated on various control devices including a g32 singlechip, and specifically, referring to fig. 2, the power consumption control method of the notebook computer comprises the following steps:
and S1, collecting the total current of the mainboard by using a current sensor.
Monitoring an identification state of the processor by establishing a connection with the processor; if the processor is successfully identified, the processor is judged to be in a working state, the collection of the total current of the mainboard is started, and the total current of the mainboard collected by the current sensor is regularly obtained according to a set current collection period.
Specifically, whether the cpu is in the working mode is judged firstly, and if the system is not in the working state (s0), most of electricity in the notebook computer does not work at this time, so that the normal charging process is directly performed without performing power limitation, namely, the mode enters the wc mode, the pc mode and the nc mode, and the high-power charging is performed. If the notebook computer is in the s0 state, the total mainboard current collected by the current sensor is read periodically.
And S2, calculating the total power according to the total current and the fixed value voltage.
Using the formula: and when the voltage of the notebook computer is a fixed value, the total power is calculated according to the collected total current of the mainboard.
And S3, comparing the total power with a set power threshold, and if the total power exceeds the power threshold, reducing the power supply charging current by updating a current limit parameter of a power supply charging program.
If the total power exceeds a set power threshold, gradually reducing the charging current of the power supply according to a set step pitch; and comparing the updated total power with a set power threshold value after adjusting the charging current each time, and stopping adjusting the charging current if the updated total power is not lower than the power threshold value.
Specifically, the calculated power consumption is compared with a threshold, and if the calculated power consumption does not exceed the threshold, power limitation is not necessary at this time, and the normal charge mode is similarly performed in the charge mode. And if the calculated power exceeds the threshold value, switching from the normal charge mode to the power limiting mode, and reducing the charging power to be below the threshold value. And under the power limiting mode, setting the step pitch to be 1A, reducing the upper limit of the charging current by 1A through one-time adjustment, re-collecting the total current of the mainboard to calculate the total power, reducing the upper limit of the charging current by 1A if the total power is still larger than the power threshold, and performing the operation in a circulating mode until the total power does not exceed the power threshold. In modifying the upper limit of the charging current, a method of modifying parameters is employed, for example, 2 8-bit data for controlling the charging current of the battery, BAT _ CC _ H upper eight bits, and BAT _ CC _ L lower eight bits are set. And converting the 16-bit 2 system into a decimal system, namely, the decimal system is a value corresponding to the maximum charging current, and modifying the unit mA into a corresponding value.
In order to reduce the influence of power consumption regulation on the charging speed, the difference value between a power threshold value and the total power is calculated, if the difference value exceeds a preset difference value threshold value, the power supply charging current is increased through updating a current limit parameter of a power supply charging program until the difference value does not exceed the difference value threshold value. That is, when the polling is performed until the power of the current corresponding to the adc is too small, the power limiting mode is released, and the charging current is increased.

a current collecting unit 310 for collecting a total current of the main board using the current sensor;
