The battery charging mode is a charging mode of the main battery 100 and the backup battery 200 by the charging power source, and at least includes a charging sequence of the main battery 100 and the backup battery 200 by the charging power source, and the like. When the power supply device is connected to the charging power supply, the electric quantity values of the main battery 100 and the standby battery 200 are obtained first, then the current battery charging mode is determined from the battery charging modes according to the electric quantity values of the main battery 100 and the standby battery 200, and then the charging power supply is controlled to charge the main battery 100 and the standby battery 200 according to the determined current battery charging mode.
When the power supply device is connected to the charging power supply, there are various situations in the power supply device for the power values of the main battery 100 and the standby battery 200, that is, there are various situations in the power supply device for the power values.

In this embodiment, the plurality of battery charging modes includes a first battery charging mode and/or a second battery charging mode. The first battery charging mode is: charging of the main battery 100 is completed first, and then charging of the backup battery 200 is completed. The second battery charging mode is: charging of the backup battery 200 is completed first, and then charging of the main battery 100 is completed.
After the electric quantity values of the main battery 100 and the backup battery 200 are acquired, when the electric quantity value of the main battery 100 is lower than a preset first electric quantity threshold value, the current battery charging mode determined from the plurality of battery charging modes is a first battery charging mode. When the electric quantity value of the main battery 100 is above the first electric quantity threshold value and the electric quantity value of the backup battery 200 is above the preset second electric quantity threshold value, the current battery charging mode determined from the plurality of battery charging modes is also the first battery charging mode.

The second power threshold may range, for example, but not limited to, 5% to 60% of the rated capacity value of the main battery 100, e.g., the second power threshold may be 20%, 35%, 40% of the rated capacity value of the main battery 100, etc.

It should be understood that the main battery 100 in the power supply device may be the main power supply to the terminal device, or may be the only power supply to the terminal device. In the former case, both the main battery 100 and the backup battery 200 may separately supply power to the terminal device. In the latter case, the backup battery 200 supplies power to the main battery 100, and the main battery 100 supplies power to the terminal device. Further, the completion of charging of the main battery 100 in the present application can be understood as: the charge of the main battery 100 is charged to a first completion value, which is greater than a first charge threshold. The first completion value is, for example, but not limited to, a rated capacity value of the main battery 100. Similarly, the completion of the charging of the backup battery 200 in the present application can be understood as: the power of the backup battery 200 is charged to a second completion value, which is greater than the second power threshold. The second completion value is, for example, but not limited to, the rated capacity value of the backup battery 200.
In some preferred embodiments, the plurality of battery charging modes includes a third battery charging mode, the third battery charging mode being: simultaneously charging the main battery 100 and the standby battery 200 until the charging of the main battery 100 and the standby battery 200 is completed; when the power level of the main battery 100 is above a preset first power level threshold and the power level of the main battery 100 is the same as the power level of the backup battery 200, the current battery charging mode is a third battery charging mode, and the first power level threshold is greater than the second power level threshold.
In the present embodiment, after the electric quantity values of the main battery 100 and the backup battery 200 are obtained, when the electric quantity value of the main battery 100 is above a preset first electric quantity threshold value and the electric quantity value of the main battery 100 is the same as the electric quantity value of the backup battery 200, the current battery charging mode determined from the plurality of battery charging modes is the third battery charging mode.

In this embodiment, since the electric quantity value of the main battery 100 is above the preset first electric quantity threshold and the electric quantities of the main battery 100 and the standby battery 200 are the same, it is indicated that the electric quantities of the main battery 100 and the standby battery 200 are all relatively large, and the control method can be optimized by charging the main battery 100 and the standby battery 200 at the same time, so as to simplify the charging control process.
Further, after the electric quantity values of the main battery 100 and the backup battery 200 are acquired, when the electric quantity value of the main battery 100 is above a first electric quantity threshold value and the electric quantity value of the backup battery 200 is above a preset second electric quantity threshold value and is different from the electric quantity value of the main battery 100, the current battery charging mode determined from the plurality of battery charging modes is the first battery charging mode.
In some preferred embodiments, the control method further comprises:
When the power supply device is not connected to the charging power supply, acquiring the electric quantity value of the main battery 100;
whether the electric quantity value of the main battery 100 is lower than a preset third electric quantity threshold value is judged, and when the electric quantity value of the main battery 100 is lower than the third electric quantity threshold value, the standby battery 200 is controlled to charge the main battery 100.
In this embodiment, when the power supply device is not connected to the charging power source, the power value of the main battery 100 is obtained first, and then it is determined whether the power value of the main battery 100 is lower than a preset third power threshold. When the power value of the main battery 100 is above the third power threshold, it is indicated that the main battery 100 may still provide a certain power to the terminal device to maintain the operation of the terminal device; when the electric quantity value of the main battery 100 is lower than the third electric quantity threshold, it is indicated that the remaining electric quantity of the main battery 100 is lower at this time, and the standby battery 200 is turned on to charge the main battery 100, so as to increase the electric quantity of the main battery 100. Since the main battery 100 is used for supplying power to the terminal device, when the electric quantity of the main battery 100 is increased, the cruising ability of the terminal device can be increased. Meanwhile, in this embodiment, when the electric quantity of the main battery 100 is lower than the third electric quantity threshold, the standby battery 200 is adopted to directly charge the main battery 100, so that the power supply device does not need to perform power-off processing when the electric energy of the standby battery 200 is used by the terminal device, and the use body feeling of the user on the aspect of the endurance time of the terminal device is improved. In addition, the existing charging mode for the main battery 100 in the power supply device is only a power adapter and a mobile power source such as a charger, and in this embodiment, the main battery 100 is charged by the standby battery 200, which breaks the existing charging mode for charging the main battery 100 in the power supply device and enriches the charging modes of the main battery 100 in the power supply device.
It should be appreciated that the third charge threshold may range from, for example, but not limited to, 2% to 30% of the rated capacity of the main battery 100. For example, the third power threshold is 10% or 20% of the rated capacity of the main battery 100, or the like.

In the present embodiment, the backup battery 200 includes a plurality of sub-batteries, each of which can charge the main battery 100. The plurality of sub-batteries sequentially charge the main battery 100 in a preset charging sequence, specifically: when the standby battery 200 is required to charge the main battery 100 each time, the first sub-battery in the charging sequence is first turned on to charge the main battery 100, and if the electric quantity of the sub-battery decreases to a preset value, the next sub-battery in the charging sequence is turned on to charge the main battery 100, and so on until the charging of the main battery 100 is completed. Of course, in some other embodiments, multiple sub-cells may be connected in series to charge the main cell 100 at the same time.
Wherein the charging sequence of the plurality of sub-batteries is, for example and without limitation, according to the placement sequence of the sub-batteries, etc. The preset value may be set according to the actual use requirement, and the range of the preset value is, for example, but not limited to, 5% or less of the total amount of the electric energy of the main battery 100. For example, the preset value is 3% or 5% of the total amount of electric power of the main battery 100, etc.
In some preferred embodiments, the sub-battery charges the main battery 100 according to a preset charging voltage and charging current. The preset charging voltage and charging current may be the rated charging voltage and current of the main battery 100 or be lower than the rated charging voltage and current of the main battery 100, so that the sub-battery charges the main battery 100 with a suitable current, thereby avoiding damage to the performance of the main battery 100.
In some preferred embodiments, before controlling the current sub-battery to charge the main battery 100, it further comprises:
Acquiring the power supply condition of the current sub-battery, wherein the power supply condition at least comprises one or more of a temperature value, a voltage value and a current value of the battery;

In this embodiment, in order to provide protection for the main battery 100 and the sub-battery, it is also necessary to detect the power supply condition of the current sub-battery before controlling the current sub-battery to charge the main battery 100. Specifically, the power supply condition of the current sub-battery is obtained, and then the power supply condition is compared with the power supply condition to judge whether the power supply condition is met. When the power supply condition does not meet the power supply condition, that is, the current sub-battery does not meet the power supply condition to the main battery 100, controlling the next sub-battery in the charging sequence to charge the main battery 100; when the power supply condition meets the power supply condition, that is, the current sub-battery meets the power supply condition to the main battery 100, the current sub-battery is controlled to charge the main battery 100.
Wherein the power supply condition includes at least one or more of a temperature value, a voltage value, and a current value of the battery. The power supply condition then corresponds in parameters to the power supply condition, for example: the power supply condition includes a temperature threshold value when the power supply condition includes a voltage value of the battery, the power supply condition includes a voltage upper limit threshold value and a voltage lower limit threshold value when the power supply condition includes a current value inside the battery, and the power supply condition includes a current threshold value. When the temperature value of the current sub-battery is higher than the temperature threshold value, the current sub-battery is in an over-temperature condition; when the voltage value of the current sub-battery is higher than the upper voltage threshold, the current sub-battery is in an overvoltage condition; when the voltage value of the current sub-battery is lower than the voltage lower limit threshold value, the current sub-battery is in an overdischarge state; and when the current value inside the current sub-battery is higher than the current threshold value, indicating that the current sub-battery is in an overcurrent condition.
