Specifically, referring to fig. 1, an embodiment of the present application provides a method for controlling battery power, where the method for controlling battery power is used for a terminal device and includes the following steps.

Step S11, the electric quantity percentage of the battery is obtained.

In this embodiment, a preprocessing step S10 is further included before step S11, where the battery capacity is divided into a plurality of power consumption intervals, each power consumption interval is N% (where N% represents a difference value of the power values displayed by the terminal device, and the capacity of the battery represents an actual available capacity of the battery), and the power consumption of each power consumption interval is N% of the current capacity of the battery.

The value of the power percentage only shows the end point value of each power consumption interval. Specifically, for example, if a certain power consumption interval is [90%,85% ], the power consumption percentage becomes 85% when the power consumption interval is completed (i.e., the capacity of the battery corresponding to 5% of the power consumption interval is consumed) if the power consumption percentage is 90%.

Step S12, judging whether the electric quantity percentage is lower than a preset threshold value.

In the embodiment of the present application, the preset threshold is used as a flag for distinguishing whether the battery is sufficiently charged. Specifically, a critical point at which the power consumption speed becomes high is generally selected.

And S13, when the electric quantity percentage is judged to be lower than the preset threshold value, controlling the battery to enter a second power consumption mode from a first power consumption mode, wherein the available battery capacity corresponding to the second power consumption mode is higher than that corresponding to the first power consumption mode.

In the embodiment of the present application, the power consumption modes of the battery are divided into a first power consumption mode and a second power consumption mode.

Specifically, the first power consumption mode is the prior art, that is, the battery capacity is divided into a plurality of power consumption intervals, each power consumption interval is N%, and the electric quantity of each power consumption interval is N% of the current capacity of the battery. Therefore, the available battery capacity of each power consumption interval is sequentially reduced, that is, the lower the power amount is, the faster the power consumption speed of each power consumption interval is. Stated another way, the first power consumption mode is when the terminal device is powered down with a power percentage of 0%, and a significant portion of the battery capacity is hidden from use.

When the battery is in the first power consumption mode, voltage drops corresponding to the power consumption intervals are increased along with the reduction of the electric quantity percentage.

And a second power consumption mode, when the electric quantity percentage of the battery is lower than a preset threshold value, re-dividing power consumption intervals, wherein each power consumption interval is a%, the electric quantity of each power consumption interval is a% of the maximum capacity of the battery, wherein a% = Q is N%/P, Q is the capacity of the battery corresponding to the preset threshold value, and P is the maximum capacity of the battery. In other words, most of the battery capacity which is hidden and not used is equally divided into each power consumption interval again, so that each power consumption interval has sufficient electric quantity, the service time of the terminal equipment in low electric quantity is prolonged, and the situation that the terminal equipment is instantly powered off to cause the user to lose communication information is avoided, thereby improving the user experience.

The specific values are further described below.

Assume that the battery capacity of the battery is 4000mah and the preset threshold is 60%.

In the prior art, the battery is in the first power consumption mode all the way. At intervals of 5% as power consumption interval, when the power percentage is 0% and the power is turned off, the battery capacity is 4000 (95%) ²⁰ = 1433.9mah, about 35.8% of the battery capacity is hidden from consumption.

In the embodiment of the application, the battery is in the first power consumption mode when the electric quantity is higher than 60%, and is in the second power consumption mode when the electric quantity is lower than 60%. At intervals of 5% as power consumption interval, when the power percentage is 0% and the power is turned off, the battery capacity is 4000 [ (95%) ] ⁸ -60％]=253.7mah, about 6.3% of the battery capacity is hidden and not consumed, compared with the prior art, most of the hidden electric quantity is released, so that the service time of the terminal equipment in low electric quantity is prolonged, and the situation that the terminal equipment is instantly powered off to cause the user to lose communication information is avoided, thereby improving the user experience.

It should be noted that, the electric quantity of the battery can be regarded as a percentage of the electric quantity displayed by the terminal device, the capacity of the battery is the actual available capacity of the battery, and the electric quantity and the capacity represent different meanings.

Referring to fig. 2, an embodiment of the present application provides a battery power control device 1, which includes a first dividing module 11, an obtaining module 12, a judging module 13, a control module 14, and a second dividing module 15.

The first dividing module 11 is configured to divide the battery capacity into a plurality of power consumption intervals, where each power consumption interval is N%, and the electric quantity of each power consumption interval is N% of the current capacity of the battery.

The acquisition module 12 is connected to the first division module 11. The acquisition module 12 is used for acquiring the electric quantity percentage of the battery.

In the embodiment of the present application, the value of the power percentage only shows the endpoint value of each power consumption interval. Specifically, for example, if a certain power consumption interval is [90%,85% ], the power consumption percentage becomes 85% when the power consumption interval is completed (i.e., the capacity of the battery corresponding to 5% of the power consumption interval is consumed) if the power consumption percentage is 90%.

The judgment module 13 is connected with the acquisition module 12. The judging module 13 is configured to judge whether the percentage of the electric power is lower than a preset threshold.

The control module 14 is connected with the judging module 13. The control module 14 is configured to control the battery to enter a second power consumption mode from a first power consumption mode when the percentage of the electric power is determined to be lower than the preset threshold, wherein the available battery capacity corresponding to the second power consumption mode is higher than the available battery capacity corresponding to the first power consumption mode.

The second dividing module 15 is connected to the control module 14. The second dividing module 15 is configured to re-divide power consumption intervals when the battery is in the second power consumption mode, wherein each power consumption interval is a%, and the electric quantity of each power consumption interval is a% of the maximum capacity of the battery, where a% = Q x N%/P, Q is the capacity of the battery corresponding to the preset threshold, and P is the maximum capacity of the battery.

Specifically, the first power consumption mode is the prior art, that is, the battery capacity is divided into a plurality of power consumption intervals, each power consumption interval is N% (the N% represents the difference value of the electric quantity values displayed by the terminal device, the battery capacity represents the actual available capacity of the battery), and the electric quantity of each power consumption interval is N% of the current capacity of the battery. Therefore, the available battery capacity of each power consumption interval is sequentially reduced, that is, the lower the power amount is, the faster the power consumption speed of each power consumption interval is. Stated another way, the first power consumption mode is when the terminal device is powered down with a power percentage of 0%, and a significant portion of the battery capacity is hidden from use.
