Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
An embodiment of the method of the present application provides a battery control method, as shown in fig. 1, the method includes the following steps:
step 101: monitoring whether a battery of an electronic device meets a switching condition when the battery of the electronic device is in a first mode;
step 102: and if the switching condition is met, controlling the battery to be switched from the first mode to the second mode.
The cut-off voltage of the battery in the first mode is a first cut-off voltage, the cut-off voltage of the battery in the second mode is a second cut-off voltage, and the electric quantity reserved for a specific chip of the electronic device by the battery under the first cut-off voltage is larger than the electric quantity reserved for the specific chip by the battery under the second cut-off voltage.
The battery of the current electronic equipment only corresponds to one cut-off voltage. In the present application, the battery corresponds to two cut-off voltages, and the different cut-off voltages of the battery correspond to different remaining electric quantities of the battery, where the remaining electric quantities refer to electric quantities left after subtracting electric quantities reserved for a specific chip of the electronic device from current actual total electric quantities of the battery. At present, the electric quantity currently displayed by the electronic equipment is the residual electric quantity obtained by subtracting the electric quantity reserved for a specific chip of the electronic equipment from the current total electric quantity, and a user generally does not know that a part of electric quantity reserved by a battery is used for the specific chip.
The specific chip of the electronic device refers to a chip that can also work normally when the electronic device is in a shutdown state, and in general, the specific chip may be an RCT (real time clock) chip, and is used for setting a system clock and ensuring the accuracy of time.
The first cut-off voltage in the present application may be a fixed value, for example, 3.25V, and the second cut-off voltage may be a fixed value, which is smaller than the first cut-off voltage, for example, 3V. However, the second cut-off voltage in the present application may not be a fixed value, and will be specifically described in detail later.
Assuming that the battery reserves the electric quantity for the specific chip in the first mode so that the specific chip can work as a first time; the battery reserves the electric quantity for the specific chip in the second mode so that the time for which the specific chip can work is the second time, and then the first time is greater than the second time.
Therefore, the battery is controlled to be switched from the first mode to the second mode by monitoring the condition that the electronic equipment meets the switching condition, and the electric quantity reserved for the specific chip of the electronic equipment by the battery under the first cut-off voltage in the first mode is larger than the electric quantity reserved for the specific chip by the battery under the second cut-off voltage in the second mode, so that the electric quantity reserved for the specific chip after the battery is switched to the second mode is reduced, the residual electric quantity is increased, the endurance time of the electronic equipment is prolonged, and the purpose of improving the endurance time of the electronic equipment based on the electric quantity reserved for the specific chip in the battery is achieved.
The present application describes different handover conditions through a second method embodiment and a third method embodiment, and specifically, the second method embodiment of the present application provides a battery control method, as shown in fig. 2, the method includes the following steps:
step 201: when a battery of the electronic equipment is in a first mode, generating a prompt item when the residual electric quantity of the battery is less than a preset electric quantity;
the residual electric quantity refers to the electric quantity left by subtracting the electric quantity reserved for a specific chip of the electronic device from the current actual total electric quantity of the battery. And the cutoff voltage of the battery in the first mode is a first cutoff voltage, and the amount of power reserved for the specific chip can be determined based on the first cutoff voltage.
Step 202: monitoring whether a predetermined operation for the prompt item is received;
and when the user determines that the switching to the second mode is needed, triggering a predetermined operation aiming at the prompt item. That is, the predetermined operation is for instructing switching to the second mode.
Step 203: and if a preset operation aiming at the prompt item is received, controlling the battery to be switched from a first mode to a second mode.
The cut-off voltage of the battery in the second mode is a second cut-off voltage, and the second cut-off voltage is smaller than the first cut-off voltage, so that the amount of electricity reserved for a specific chip by the battery is reduced, and the residual electricity of the battery is increased.
For example, the first cut-off voltage is 3.25V, and the second cut-off voltage is 3.0V, so that the remaining capacity of the battery can be increased by at least 3% -5%, the increase of the endurance time is realized, and the electronic device can be ensured to delay shutdown.
An embodiment of the method of the present application provides a battery control method, as shown in fig. 3, the method includes the following steps:
step 301: learning user behavior for the electronic device;
the user behavior is used for representing a behavior that the user uses the external power supply of the electronic equipment based on the remaining capacity of the battery, that is, the user may determine whether the external power supply of the electronic equipment is used based on the currently displayed remaining capacity in the process that the user uses the electronic equipment without a power supply. By learning such behavior of the user, it is determined whether the electronic apparatus is in an emergency state.
It should be noted that step 301 is not limited to be located before step 302, and the learning of the user behavior may occur in the whole process of using the electronic device by the user.
Step 302: when a battery of the electronic equipment is in a first mode and the residual electric quantity of the battery is smaller than a preset electric quantity, determining whether the electronic equipment is in an emergency state or not based on the user behavior;
the user behavior is determined through learning that when the residual capacity of the battery is still remained, the electronic equipment is externally connected with a power supply, and if the residual capacity of the battery is smaller than the preset capacity, the electronic equipment is determined to be in an emergency state and needs to be switched. This may generally mean that a ratio of a frequency of the external power supply for the electronic device by the user to a total frequency of using the electronic device for a period of time is greater than a preset ratio.
If the user action is to exhaust the remaining power of the battery of the electronic device, so that the electronic device is automatically powered off, if the remaining power of the battery is less than the preset power, it can be determined that the electronic device is in a normal state, but not in an emergency state, and the mode does not need to be switched. The general method may refer to that a ratio of a frequency of exhausting the remaining power of the battery of the electronic device to a total frequency of using the electronic device for a period of time is greater than a preset ratio.
Step 303: and if the electronic equipment is determined to be in the emergency state, controlling the battery to be switched from the first mode to the second mode.
Wherein a cut-off voltage of the battery in the first mode is a first cut-off voltage, and a cut-off voltage of the battery in the second mode is a second cut-off voltage; the battery reserves the electric quantity of a specific chip of the electronic device under the first cut-off voltage to be larger than the electric quantity reserved for the specific chip under the second cut-off voltage.
Therefore, in the embodiment, whether the battery is switched from the first mode to the second mode when the remaining capacity of the battery is smaller than the preset capacity is determined through learning of user behaviors, so that the accuracy of mode switching is improved, the endurance time of the electronic equipment can be prolonged by switching the modes in an emergency state, and the purpose of improving the endurance time of the electronic equipment based on the capacity reserved for a specific chip in the battery is achieved.
An embodiment of the method provides a battery control method, as shown in fig. 4, the method includes the following steps:
step 401: monitoring whether a battery of an electronic device meets a switching condition when the battery of the electronic device is in a first mode;
step 402: if the switching condition is met, controlling the battery to be switched from a first mode to a second mode;
wherein the cutoff voltage of the battery in the first mode is a first cutoff voltage, and the cutoff voltage of the battery in the second mode is a second cutoff voltage; the battery reserves the electric quantity of a specific chip of the electronic device under the first cut-off voltage to be larger than the electric quantity reserved for the specific chip under the second cut-off voltage.
Step 403: when the battery is determined to be subjected to low-voltage protection, switching from the second mode to the first mode.
The low voltage protection is also called UVP protection and can be triggered when the battery is in an abnormal working state so as to protect the battery. For example, the system can trigger UVP protection when a sudden drop in the temperature of the battery is detected, or when the battery is suddenly shorted, in which case the battery can be controlled to switch from the second mode to the first mode to ensure that the amount of power reserved for a particular chip of the electronic device is sufficient.
Alternatively, as another condition for switching from the second mode to the first mode, specifically, it may be determined that the actual remaining capacity of the battery is 0. It can be understood that when the remaining capacity of the battery is lower than a preset remaining capacity, the electronic device is triggered to automatically shut down, and the remaining capacity refers to the remaining capacity obtained by subtracting the capacity reserved for a specific chip of the electronic device from the current actual total capacity of the battery. After the electronic device is automatically powered off, the battery actually has a certain amount of power, which is used to supply power to a specific chip of the electronic device, and then when the actual remaining power of the battery is 0, that is, the reserved power is also consumed, the battery is triggered to be switched from the second mode to the first mode.
Fifth embodiment of the present application further provides a battery control method, as shown in fig. 5, the method includes the following steps:
step 501: monitoring whether a battery of an electronic device meets a switching condition when the battery of the electronic device is in a first mode;
step 502: if the switching condition is met, controlling the battery to be switched from a first mode to a second mode;
wherein the cutoff voltage of the battery in the first mode is a first cutoff voltage, and the cutoff voltage of the battery in the second mode is a second cutoff voltage; the power reserved by the battery to a specific chip of the electronic device under the first cut-off voltage is larger than the power reserved by the battery to the specific chip under the second cut-off voltage.
Step 503: recording a first residual capacity of the battery when the battery is switched from a first mode to a second mode in the first mode;
under different cut-off voltages, the electric quantity reserved for a specific chip is different, so that the residual electric quantity of the electronic equipment in different modes at the same moment is different, and the endurance time of the corresponding electronic equipment is different. Fig. 6 is a schematic diagram showing discharge curves of the battery in different modes.
The first remaining capacity refers to a capacity left by subtracting a capacity reserved for a specific chip of the electronic device, which is determined based on the first cut-off voltage, from the current actual total capacity of the battery when the battery is switched from the first mode to the second mode in the first mode.
Step 504: calculating a second remaining capacity after switching to the second mode;
the second remaining capacity refers to a capacity left after the battery is in the second mode and the current actual total capacity of the battery is subtracted by a capacity reserved for a specific chip of the electronic device, which is determined based on the second cutoff voltage.
Since the second off-voltage is smaller than the first off-voltage, the amount of power reserved for the specific chip in the second mode is smaller than the amount of power reserved for the specific chip in the first mode.
Step 505: and determining the residual capacity displayed by the user based on the second residual capacity and the first residual capacity.
And the residual capacity for displaying is less than or equal to the first residual capacity.
In this embodiment, in order to keep the displayed remaining power smooth and avoid the situation that the displayed remaining power jumps up after switching, after the second remaining power is determined, the second remaining power may be processed based on the first remaining power, for example, the difference between the second remaining power and the first remaining power is subtracted on the basis of the second remaining power to obtain the remaining power for displaying, so that the remaining power displayed by the user is less than or equal to the first remaining power.
Sixth embodiment of the method of the present application provides a method for controlling a battery, and as shown in fig. 7, the method includes the following steps:
step 701: learning a frequency of use of the electronic device by a user;
specifically, the number of times the user uses the electronic device over a period of time may be learned.
Step 702: determining a required power amount of a specific chip of the electronic device based on the use frequency, and determining a second cut-off voltage based on the required power amount of the specific chip;
the high use frequency means that the time when the electronic device is turned off is relatively short, and then the power required by the specific chip is low, and the low use frequency means that the time when the electronic device is turned off is relatively long, and then the power required by the specific chip is high. The second off-voltage may be smaller when the amount of power required for the specific chip is small, and may be larger when the amount of power required for the specific chip is large. The specific corresponding relationship may be set based on actual conditions, and the present application is not limited.
For example, the second cut-off voltage is V1, and the electric quantity reserved for the specific chip is X1, so that the specific chip can maintain working for a first time length in the shutdown state of the electronic device; the second cut-off voltage is V2, and the electric quantity reserved for the specific chip is X2, so that the specific chip can maintain working for a second time length in the shutdown state of the electronic device. Wherein, V1 is greater than V2, X1 is greater than X2, and the first time span is greater than the second time span.
Step 703: monitoring whether a battery of an electronic device meets a switching condition when the battery of the electronic device is in a first mode;
step 704: and if the switching condition is met, controlling the battery to be switched from the first mode to the second mode.
Wherein the cutoff voltage of the battery in the first mode is a first cutoff voltage, and the cutoff voltage of the battery in the second mode is a second cutoff voltage; the battery reserves the electric quantity of a specific chip of the electronic device under the first cut-off voltage to be larger than the electric quantity reserved for the specific chip under the second cut-off voltage.
Corresponding to the battery control method, the embodiment of the device of the application provides electronic equipment. Specifically, an embodiment of the apparatus of the present application provides an electronic device, as shown in fig. 8, the electronic device includes a battery 810, a target chip 820, and a processor 830; wherein:
the processor 830 is configured to monitor whether the electronic device meets a switching condition when the battery 810 is in the first mode, and control the battery 810 to switch from the first mode to the second mode if the switching condition is met.
Wherein a cut-off voltage of the battery in the first mode is a first cut-off voltage, and a cut-off voltage of the battery in the second mode is a second cut-off voltage; the amount of power reserved by the battery to the target chip 820 at the first cut-off voltage is larger than the amount of power reserved by the battery to the target chip 820 at the second cut-off voltage.
The target chip 820 is a chip capable of normally working in a shutdown state of the electronic device, and in general, the target chip may be an RCT (real time clock) chip for setting a system clock and ensuring time accuracy.
The first cut-off voltage in the present application may be a fixed value, for example, 3.25V, and the second cut-off voltage may be a fixed value, which is smaller than the first cut-off voltage, for example, 3V. However, the second cut-off voltage in the present application may not be a fixed value, and will be specifically described in detail later.
Therefore, the battery is controlled to be switched from the first mode to the second mode by monitoring the condition that the electronic equipment meets the switching condition, and the electric quantity reserved for the specific chip of the electronic equipment by the battery under the first cut-off voltage in the first mode is larger than the electric quantity reserved for the specific chip by the battery under the second cut-off voltage in the second mode, so that the electric quantity reserved for the specific chip after the battery is switched to the second mode is reduced, the residual electric quantity is increased, the endurance time of the electronic equipment is prolonged, and the purpose of improving the endurance time of the electronic equipment based on the electric quantity reserved for the specific chip in the battery is achieved.
An embodiment of the apparatus of the present application provides an electronic device, as shown in fig. 9, where the electronic device includes: battery 910, target chip 920, processor 930, display 940; wherein:
and a processor 940, configured to generate a prompt item when the battery 910 is in the first mode and the remaining power of the battery 910 is less than a preset power, output the prompt item through the display 940, monitor whether a predetermined operation for the prompt item is received, and control the battery 910 to switch from the first mode to the second mode if the predetermined operation for the prompt item is received.
The prompt item is used for prompting the user whether to switch to the second mode, and the preset operation is used for indicating to switch to the second mode.
The residual electric quantity refers to the electric quantity left by subtracting the electric quantity reserved for a specific chip of the electronic device from the current actual total electric quantity of the battery. And the cutoff voltage of the battery in the first mode is a first cutoff voltage, and the amount of power reserved for the specific chip can be determined based on the first cutoff voltage.
The cut-off voltage of the battery in the second mode is a second cut-off voltage, and the second cut-off voltage is smaller than the first cut-off voltage, so that the amount of electricity reserved for a specific chip by the battery is reduced, and the residual electricity of the battery is increased.
In a third embodiment of the apparatus of the present application, the processor is further configured to learn user behavior for the electronic device; the user behavior is used for representing the behavior of a user for connecting the external power supply of the electronic equipment based on the residual electric quantity of the battery; the processor monitors whether the electronic device meets a switching condition, including: and when the residual capacity of the battery is less than the preset capacity, determining whether the electronic equipment is in an emergency state or not based on the user behavior.
The user behavior is used for representing a behavior that the user uses the external power supply of the electronic equipment based on the remaining capacity of the battery, that is, the user may determine whether the external power supply of the electronic equipment is used based on the currently displayed remaining capacity in the process that the user uses the electronic equipment without a power supply. By learning such behavior of the user, it is determined whether the electronic apparatus is in an emergency state.
Therefore, in the embodiment, whether the battery is switched from the first mode to the second mode when the remaining power of the battery is smaller than the preset power is determined through learning of user behaviors, so that the accuracy of mode switching is improved, the endurance time of the electronic equipment can be prolonged by switching the modes in an emergency state, and the purpose of improving the endurance time of the electronic equipment based on the power reserved for a specific chip in the battery is achieved.
In a fourth embodiment of the device of the present application, the processor is further configured to switch from the second mode to the first mode when it is determined that the battery is under low voltage protection.
The low voltage protection, also known as UVP protection, can be triggered when the battery is in an abnormal operating state to protect the battery. For example, the system can trigger UVP protection when a sudden drop in the temperature of the battery is detected, or when the battery is suddenly shorted, in which case the battery can be controlled to switch from the second mode to the first mode to ensure that the amount of power reserved for a particular chip of the electronic device is sufficient.
Optionally, as another condition for switching from the second mode to the first mode, it may be specifically determined that the actual remaining capacity of the battery is 0. It can be understood that when the remaining capacity of the battery is lower than a preset remaining capacity, the electronic device is triggered to automatically shut down, and the remaining capacity refers to the remaining capacity obtained by subtracting the capacity reserved for a specific chip of the electronic device from the current actual total capacity of the battery. After the electronic device is automatically powered off, the battery actually has a certain amount of power, which is used for supplying power to a target chip of the electronic device, and then when the actual remaining power of the battery is 0, that is, the reserved power is also consumed, the processor triggers the battery to switch from the second mode to the first mode.
In a fifth embodiment of the apparatus of the present application, on the basis of the first embodiment of the apparatus, the electronic device further includes: a display; the processor is further configured to record a first remaining capacity of the battery when the battery is switched from the first mode to the second mode in the first mode, calculate a second remaining capacity after the battery is switched to the second mode, determine a remaining capacity for displaying on the display based on the second remaining capacity and the first remaining capacity, and enable the remaining capacity for displaying on the display to be less than or equal to the first remaining capacity.
The first remaining capacity refers to a capacity left by subtracting a capacity reserved for a specific chip of the electronic device, which is determined based on the first cut-off voltage, from the current actual total capacity of the battery when the battery is switched from the first mode to the second mode in the first mode.
The second remaining capacity refers to a capacity left by subtracting a capacity reserved for a specific chip of the electronic device, which is determined based on the second cutoff voltage, from the current actual total capacity of the battery in the second mode. Since the second off-voltage is smaller than the first off-voltage, the amount of power reserved for the specific chip in the second mode is smaller than the amount of power reserved for the specific chip in the first mode.
In this embodiment, in order to keep the displayed remaining power smooth and avoid the situation that the displayed remaining power jumps up after switching, after the second remaining power is determined, the second remaining power may be processed based on the first remaining power, for example, the difference between the second remaining power and the first remaining power is subtracted on the basis of the second remaining power to obtain the remaining power for displaying, so that the remaining power displayed by the user is less than or equal to the first remaining power.
In a sixth embodiment of the apparatus of the present application, the processor is further configured to learn a frequency of use of the electronic device by the user; determining the power required by the specific chip based on the usage frequency, and determining the second cut-off voltage based on the power required by the specific chip.
The high use frequency means that the time when the electronic device is turned off is relatively short, and then the power required by the specific chip is low, and the low use frequency means that the time when the electronic device is turned off is relatively long, and then the power required by the specific chip is high. The second cutoff voltage may be smaller when the amount of power required by the specific chip is small, and the second cutoff voltage may be larger when the amount of power required by the specific chip is large. The specific corresponding relationship may be set based on actual conditions, and the present application is not limited.
