The steps illustrated in the flow charts of the figures may be performed in a computer system such as a set of computer-executable instructions. Also, while a logical order is shown in the flow diagrams, in some cases, the steps shown or described may be performed in an order different than here.
Fig. 1 is a flowchart of a method for controlling a charging current according to an embodiment of the present invention, as shown in fig. 1, including:
step 100, determining the maximum charging output current output to a terminal by a charging device;
it should be noted that the maximum charging output current output from the charging device to the terminal may be obtained by reading attribute parameters of the charging device; generally, the charging output maximum current commonly available on the market includes: 1 an, 1.5 an, 2 an, etc.
Step 101, setting battery charging current corresponding to each charging stage of terminal charging;
optionally, the charging stage in the embodiment of the present invention includes: trickle charge stage, pre-charge stage, constant current charge stage, constant voltage charge stage, after the battery is over-discharged or the voltage is lower than the minimum charge voltage stage; the setting of the battery charging current corresponding to each charging phase comprises:
a trickle charge stage, wherein the battery charging current is set to be a charging current with a preset magnitude; here, the charging current of a preset magnitude includes: a charging current of less than 100 milliamps.
A pre-charging stage, setting the battery charging current as a first preset percentage of the rated charging current; here the first predetermined percentage may be around 10%.
In the constant current charging stage, setting the charging current of the battery as the rated charging current;
it should be noted that the rated charging current may be an interval value, where the maximum value is generally the maximum current that the battery can provide support, and is generally the calibrated maximum charging current; the minimum value is the minimum charging current value required to be guaranteed, the common charging requirement can be met, and the minimum value can be adjusted according to the terminal operation condition.
In the constant voltage charging stage, the battery charging current is set according to the voltage difference between the internal voltage and the external voltage of the battery and the internal resistance value of the battery;
it should be noted that the initial battery charging current is generally small, and according to the change of the voltage difference between the internal voltage and the external voltage of the battery, the battery charging current is continuously reduced along with the charging time, and the battery charging current is also smaller and smaller; the embodiment of the invention can set smaller battery charging current. It is generally sufficient to set 10% of the maximum current that the battery can provide support.
And after the battery is over-discharged or the voltage is lower than the minimum charging voltage stage, setting the charging current of the battery to be a second preset percentage of the rated charging current. Here the second preset percentage may be around 10%.
And 102, calculating the corresponding maximum working current of each charging stage according to the obtained charging output maximum current and the set maximum battery charging current of each charging stage.
It should be noted that, in the embodiment of the present invention, the maximum working current can be obtained by setting the maximum battery charging current in each charging stage; the maximum working current obtained by setting and calculating the maximum battery charging current can realize the balance of the charging process and the system work.
If Imax represents the maximum charging output current output from the charging equipment to the terminal; ibat, representing the charging current of the battery corresponding to each charging stage of the terminal charging; isys represents the corresponding maximum working current of each charging stage; then Isys is Imax-Ibat.
The corresponding maximum operating current for each charging phase may also be calculated by the following equation:
Isys＝(Vbatsense-Vsys_min)*1000/RAC
wherein Vbase sense is a voltage value on a terminal hardware path; vsys _ min is the minimum voltage value for supplying power to the terminal module, for example, Vsys is 3.4V-4.2V, and Vsys _ min is 3.4V, below which the terminal module cannot work normally. RAC is the internal resistance of the battery, and the internal resistance of the battery is obtained by inquiring the battery meter according to the battery temperature TS obtained by the temperature detection module of the current voltage Vbat charging module.

and calculating the product of the power ratio and the power difference value, and performing power adjustment on the module.
It should be noted that, if the sum of the powers obtained by the calculation is greater than the maximum operating power of the terminal obtained by the calculation, the power difference is greater than 0, that is, the actual powers of all the modules of the terminal are greater than the output power of the terminal during charging, and at this time, performing power adjustment on the modules generally includes reducing the powers of the modules. If the sum of the calculated powers is smaller than the calculated maximum working power of the terminal, the power difference is smaller than 0, that is, the actual powers of all the modules of the terminal are smaller than the output power of the terminal during charging, and at this time, performing power adjustment on the modules generally includes increasing the power of the modules.
The embodiment of the invention assumes a module A power value Pcur1 and a module B power value Pcur2 …; calculating the sum of the power of the actual power of each module contained in the terminal as Pcur1+ Pcur2+ …; the sum of the powers is greater than the maximum power of the terminal, indicating that the use of the current module needs to be limited to ensure that the maximum charging current Ibat of the battery is maintained above Ibat _ min; for one or more modules included in the terminal, calculating a power ratio of the actual power of each module to the sum of the powers, for example, calculating the power ratio for module a as X1 ═ Pcur1/(Pcur1+ Pcur2+ …); calculating a power ratio for module B of X2 ═ Pcur2/(Pcur1+ Pcur2+ …); calculating the product of the power ratio and the power difference, and performing power adjustment on the module comprises the following steps: calculating P1 (Pcur1+ Pcur2+ … -Pmax) X1 for module A, and adjusting the power reduction P1 for module A; block B was adjusted to reduce power P2 by calculating P2 (Pcur1+ Pcur2+ … -Pmax) × X2.
