a charging control method of a mobile terminal, a charging control apparatus of a mobile terminal, an electronic device, and a non-transitory computer-readable storage medium according to embodiments of the present application are described below with reference to the accompanying drawings.
fig. 1 is a flowchart of a charging control method of a mobile terminal according to an embodiment of the present application. As shown in fig. 1, the method comprises the steps of:
And S1, entering a constant current charging mode, and acquiring the current temperature and current of the battery of the mobile terminal.
And S2, determining the corresponding floating pressure according to the current temperature and current of the battery.
Further, in an embodiment of the present application, determining the corresponding floating voltage according to the present temperature and the present current of the battery may include: inquiring a comparison table according to the current temperature and the current of the battery to obtain corresponding floating pressure, wherein the comparison table is obtained through experiments, and the experiments comprise: and acquiring temperature values of the battery under different currents and voltage resistance values of the battery under different currents. The battery temperature is inversely proportional to the internal resistance of the battery, which is related to the float pressure.
Specifically, due to the existence of the direct current impedance and the polarization impedance in the battery cell, when the battery is charged, the current voltage of the battery floats high, that is, there is a floating voltage V1, OCV ═ V1+ VBAT, where OCV is the current voltage of the battery, V1 is the floating voltage, VBAT is the actual voltage of the battery, and V1 ═ I × R, where I is the current of the battery, R is the internal resistance of the battery, and the internal resistance includes the direct current impedance and the polarization impedance. Since, as shown in fig. 3, the internal resistance of the battery is related to the temperature of the battery, the internal resistance of the high-temperature battery is small, the internal resistance of the low-temperature battery is large, and the temperature of the battery is related to the current of the battery. Therefore, the temperature values T of the battery under different currents I can be measured and obtained in advance through related experiments, and the relation curve is generally shown in fig. 4; and then, the maximum withstand voltage value Vmax of the battery under different currents I is measured through correlation, namely, the maximum voltage value of the battery, which can not damage the battery, under different currents I is measured, a relation curve is generally shown in fig. 5, and the maximum withstand voltage value Vmax is subtracted from the rated voltage VBAT of the battery, so that the floating voltage of the battery under the corresponding current I can be obtained. Therefore, by combining the graphs of fig. 4 and 5, the distribution of the floating voltage of the battery at a specific temperature and current can be obtained through the analysis of the relevant data, and the distribution is pre-stored in the form of a table. The floating pressure V1 corresponding to the current temperature and current of the battery can be obtained by inquiring the floating pressure distribution table.
And S3, acquiring the rated voltage of the battery, and charging the battery according to the floating voltage and the rated voltage.
Further, charging the battery according to the floating voltage and the rated voltage may include: generating cut-off voltage according to the floating voltage and the rated voltage, and acquiring corresponding cut-off current according to the cut-off voltage; if the current voltage reaches the cut-off voltage, switching to a constant voltage charging mode; if the present current reaches the cutoff current, the charging is terminated.
Specifically, due to the existence of the direct current impedance and the polarization impedance in the battery cell, when the battery is charged, the current voltage of the battery floats high, and a floating voltage V1 exists, that is, as shown in fig. 2, the current voltage of the battery is equal to the sum of the floating voltage and the actual voltage of the battery, that is, OCV 1+ VBAT, where OCV is the current voltage of the battery, V1 is the floating voltage, and VBAT is the actual voltage of the battery.
In the related art, since VBAT cannot be measured, only OCV can be measured, and therefore, whether to enter the constant voltage charging mode is determined according to the current voltage OCV and the rated voltage of the battery, that is, if the current voltage OCV of the battery reaches the rated voltage, the constant voltage charging mode is entered. The inventor finds that the battery cannot be damaged as long as the actual voltage VBAT of the battery does not exceed the rated voltage through a great deal of experiments. In the whole charging period, the longer the charging time of the constant-current charging mode is, the faster the charging time is, and in order to increase the charging speed, the constant-current charging time needs to be increased as much as possible, so that the constant-voltage charging time is reduced.
Therefore, in the present application, after entering the constant current charging mode, the current temperature and the current of the battery of the mobile terminal are obtained, and then the corresponding floating voltage V1 is obtained by querying the preset floating voltage distribution table according to the current temperature and the current. Then, the voltage threshold for entering the constant voltage charging mode from the constant current charging mode, that is, (V1+ VBAT) is obtained from the float voltage and the rated voltage as a cutoff voltage (voltage threshold for entering the constant voltage charging mode from the constant current charging mode), and the voltage threshold for switching to the constant voltage charging mode is increased. Therefore, the constant-current charging time can be prolonged, the constant-voltage charging time is reduced, the charging efficiency is effectively improved, and the battery can be prevented from being damaged by overvoltage. Meanwhile, the corresponding cut-off current is obtained according to the cut-off voltage, and after the constant voltage charging mode is entered, if the current of the battery reaches the cut-off current, the charging is terminated, and the charging of the mobile terminal is completed.
To sum up, according to the charging control method of the mobile terminal in the embodiment of the present application, when entering the constant current charging mode, the current temperature and the current of the battery of the mobile terminal are obtained, the corresponding floating voltage is determined according to the current temperature and the current of the battery, then the rated voltage of the battery is obtained, and the battery is charged according to the floating voltage and the rated voltage. The method charges the battery according to the floating voltage and the rated voltage, can improve the constant-current charging time, reduce the constant-voltage charging time, effectively improve the charging efficiency, and can ensure that the battery is not damaged by overvoltage.
