Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the invention.
It should be understood that in the description of the embodiments of the present invention, if there is any description of "first", "second", etc., it is only for the purpose of distinguishing technical features, and it is not to be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features or implicitly indicating the precedence of the indicated technical features. "at least one" means one or more, "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, and means that there may be three relationships, for example, a and/or B, and may mean that a exists alone, a and B exist simultaneously, and B exists alone. Wherein A and B can be singular or plural. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship. "at least one of the following" and similar expressions refer to any group of items, including any group of singular or plural items. For example, at least one of a, b, and c may represent: a, b, c, a and b, a and c, b and c or a and b and c, wherein a, b and c can be single or multiple.
In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
A battery system of an electronic device generally includes a battery module (hereinafter, referred to as a battery for short), and a power supply control device, where the battery module outputs a power supply voltage to the power supply control device, and the battery module converts the power supply voltage into a working voltage adapted to a load to the power supply control device, and outputs the working voltage to a corresponding load (e.g., a memory, a sensor, an encryption chip, an indicator light, etc.) through a power rail. Generally, when the supply voltage of the battery module is reduced to a certain level (e.g., 3.3V), the device is powered off and the device is not usable, and the device can be continuously powered on and used only by recharging the device. However, this is often biased by the user's needs, and the user often wants to prolong the service life of the device as much as possible, and requires the device to have a high battery module endurance.
In order to improve the cruising ability of a battery module of the equipment, the electronic equipment generally has a working mode and a standby mode, and the battery module of the equipment outputs normal high power supply voltage in the working mode; in the standby mode, the battery module of the device outputs a low supply voltage to reduce the battery module power consumption. When the device is in standby mode, transient high power consumption may often occur due to a weak signal causing some load voltages to rise, reducing battery module endurance.
Before the standby mode is changed into the working mode, the supply current output by the battery module is generally relatively small (about 5 mA), when the standby mode is changed, a large current peak (such as 100 mA) generally occurs, and at this time, part of the power rails are switched from the standby mode with low power consumption to the normal working mode, that is, the working voltage output by the power rails is increased from the level with low power consumption to the level with normal working. However, this is problematic when the battery module is in a low state, and when the battery module is in a low state, as the remaining charge in the battery module decreases, the battery module voltage decreases, the internal resistance of the battery module increases, and the peak value of the current that can be supplied decreases. In this case, if all power rails are restored to a normal operating level, the voltage of the battery module is pulled down instantaneously, and the battery module itself has a protection mechanism, which may trigger the shutdown of the software or hardware of the device. Additionally, when the ambient temperature is relatively low, the charge activity of the battery module is reduced, and the overall current that can be supplied is also greatly reduced, and if all power rails are restored to the normal operating level from the standby mode at this time, hardware shutdown of the trigger device is more easily caused. In this case, some important loads (such as a memory and a cryptographic chip) may be powered down instantaneously, which may damage part of data therein, and may even cause device damage.
Based on the foregoing problems, embodiments of the present invention provide a power supply control method, a power supply control apparatus, an electronic device, and a computer-readable storage medium, which dynamically manage and control a working voltage output by a power rail according to a power supply voltage output by a battery module, so as to reduce instantaneous high power consumption, and reduce a endurance time of the battery module of the device and a risk of shutdown.
Referring to fig. 1, an electronic device according to an embodiment of the invention is shown. As shown in fig. 1, an electronic device 10 provided in an embodiment of the present invention includes: battery module 11, power supply control device 12, and at least one load 14. The output end of the battery module 11 is connected with the input end of the power supply control device 12, so that the battery module 11 outputs a power supply voltage to the power supply control device 12; the power supply control device 12 is correspondingly connected to the at least one load 14 through at least one power rail 13 to output an operating voltage to the load 14. For example, as shown in fig. 1, the power supply control device 12 is connected to the n loads 14 through the n power rails 13 in a one-to-one correspondence.
By way of example and not limitation, the electronic device 10 according to the embodiment of the present invention may be a tracking locator (tracer), for example, a tracking locator designed for elderly people and children to prevent loss, which is carried on a positioning object when in use, and the real-time position and walking route of the positioning object can be queried through application software. In order to avoid the situation that the tracking and positioning function cannot be achieved due to low power-off of the equipment, the tracking and positioning device is generally required to have lasting cruising ability.
The electronic device 10 may also be a wearable device, such as a smart bracelet, smart belt, or the like for performing vital signs monitoring. It should be noted that the embodiment of the present invention does not limit the specific type of the electronic device 10.
For example, the load 14 according to the embodiment of the present invention may be a memory, a sensor, an encryption chip, or an indicator light, which are disposed in the electronic device 10, wherein the memory and the sensor may be memories and sensors of a Central Processing Unit (CPU).
Referring to fig. 2, a power supply control method provided by an embodiment of the invention is shown, and is applied to a power supply control device in the electronic device shown in fig. 1. As shown in fig. 2, the power supply control method provided in the embodiment of the present invention includes the following steps:
and S110, acquiring the current output power supply voltage of the battery module.
And S120, determining a voltage threshold corresponding to each power rail.
It can be understood that, in the embodiments of the present invention, voltage thresholds are respectively configured for the power rails according to the loads correspondingly connected to the power rails. When the number of the power rails is multiple, the voltage thresholds corresponding to any two power rails may be the same or different. For example, in fig. 1, the voltage threshold values corresponding to the power supply rails #1 and #2 are 3.3V, and the voltage threshold values corresponding to the power supply rails #3 and #4 are 5V.
And S130, determining the power rail corresponding to the voltage threshold value larger than the power supply voltage as a target power rail.
It can be understood that, in the embodiment of the present invention, the voltage threshold of each power rail is respectively compared with the power supply voltage obtained from the battery module, and if one or more voltage thresholds are greater than the power supply voltage currently output by the battery module, the power rail corresponding to the voltage threshold greater than the power supply voltage is determined as the target power rail. Following the foregoing example, assuming that the current output power supply voltage of the battery module is 4V, and the voltage thresholds corresponding to the power rails #3 and #4 are 5V, the power rails #3 and #4 are determined as the target power rails.
The comparison of the voltage threshold with the supply voltage can be implemented by a hardware comparator. For example, a comparator is provided for each power rail, a reference signal equal to a voltage threshold is input at one input terminal of the comparator, a supply voltage of the battery module is input at the other input terminal of the comparator, and a comparison result is obtained based on a level signal output from an output terminal of the comparator. The comparison between the voltage threshold and the power supply voltage may also be implemented by software code, and the embodiment of the present invention is not limited in any way.
And S140, reducing the working voltage output by the target power supply rail.
It will be appreciated that after the target power rail is determined, the operating voltage output by the target power rail is adjusted such that the operating voltage output by the target power rail is reduced. For example, the power rails #3 and #4 in fig. 1 are determined as the target power rails, so that the operating voltages output by the power rails #3 and #4 are adjusted, and the operating voltages output by the power rails #3 and #4 after adjustment are lower than the initial operating voltage, for example, the voltage originally output by the power rails #3 and #4 is 4V, and the voltage output after adjustment is 2V.
When the power supply voltage of the battery module is lower than the voltage threshold, the battery module can be considered to be in a low-power state currently, and in order to avoid reduction of endurance time or shutdown of equipment caused by transient increase of load voltage, the embodiment of the invention manages and controls the working voltage output by the target power rail when the battery module is in the low-power state, so that the working voltage output by the target power rail is reduced, specifically, the target power rail can output a minimum voltage capable of maintaining load operation, and stable operation of the load can be ensured.
According to the embodiment of the invention, when the battery module is in the low-power state, the working voltage output by part or all of the power supply rails is reduced, so that the endurance time of the battery module is prolonged, and the instantaneous high power consumption in the low-power state is avoided, thereby avoiding the risk of shutdown and even damage of equipment caused by the reduction of the working voltage.
In one possible scenario, when the electronic device is in the standby mode, the supply current output by the battery module is relatively small (typically about 5 mA), and the battery supply voltage may be higher than the voltage threshold of each power rail. When the electronic device is switched from the standby mode to the operating mode, a large current peak (for example, 100 mA) generally occurs, the power supplied by the battery is limited, and in a certain power condition, when the current used by the device increases, the supply voltage of the battery decreases accordingly. When the power supply voltage is lower than the voltage threshold of one or more power supply rails, the power supply control device of the embodiment of the invention reduces the working voltage output by the corresponding power supply rail, maintains the stable work of the load and simultaneously avoids triggering the equipment to shut down, thereby avoiding data damage or equipment damage caused by sudden shutdown of the equipment and playing a role in protecting the equipment.
In an actual implementation process, the voltage threshold of the power rail connected to the load may be configured according to the importance of the load.
For example, the loads of the embodiment of the present invention are divided into the important load and the secondary load, and different voltage thresholds are configured for the power rail connected to the important load and the power rail connected to the secondary load, respectively. For example, if the load connected to the power rail is an important load, the voltage threshold corresponding to the power rail is the first voltage threshold; if the load connected to the power rail is a secondary load, the voltage threshold corresponding to the power rail is a second voltage threshold; wherein the first voltage threshold is less than the second voltage threshold.
Correspondingly, referring to fig. 3, step S120 of determining the voltage threshold corresponding to each power rail includes the following steps:
s121, determining the type of a load correspondingly connected with each power rail;
S122A, when the load correspondingly connected with the power supply rail is an important load, determining that a voltage threshold value corresponding to the power supply rail is a first voltage threshold value;
and S122B, when the load correspondingly connected with the power supply rail is a secondary load, determining that the voltage threshold corresponding to the power supply rail is a second voltage threshold.
It can be understood that, in the embodiment of the present invention, a lower voltage threshold (a first voltage threshold) is configured for the power rail connected to the important load, and a higher voltage threshold (a second voltage threshold) is configured for the power rail connected to the secondary load, and in such a configuration, during the reduction of the battery supply voltage, the operating voltage of the power rail connected to the secondary load is preferentially adjusted to ensure that a normal operating voltage is provided for the important load as much as possible, so as to avoid affecting the operating performance of the important load. The operating voltage of the power supply rail connected to the important load is only regulated when the battery supply voltage drops further and below the first voltage threshold.
In an actual implementation process, different voltage regulation strategies can be configured for a power rail connected with an important load and a power rail connected with a secondary load respectively.
For example, referring to fig. 4A, step S140 is to reduce the operating voltage output by the target power rail, and specifically includes the following steps:
S141A, when the load correspondingly connected with the target power supply rail is an important load, determining a target working voltage corresponding to the important load;
and S141B, adjusting the working voltage output by the target power supply rail from the initial working voltage to a target working voltage, wherein the target working voltage is smaller than the initial working voltage.
It can be understood that, for a target power rail connected with a critical load, the voltage regulation strategy is to regulate the operating voltage of the power rail from an initial operating voltage to a target operating voltage, so that the critical load is in a low power consumption operating state. The initial operating voltage represents the operating voltage output by the target power rail before the operating voltage output by the target power rail is reduced, and is generally the normal operating voltage provided by the power rail for an important load in the device operating mode/standby mode; the target operating voltage may be understood as the lowest operating voltage for maintaining the operation of the important load, and the target operating voltage should be less than the normal operating voltage that the power rail provides for the important load in the device operating mode/standby mode.
It can be understood that the minimum operating voltages corresponding to different important loads may be different, so that before the operating voltage output by the target power rail is adjusted, the minimum operating voltage of the important load connected to the target power rail needs to be determined, and the minimum operating voltage is taken as the target operating voltage.
For example, referring to fig. 4B, step S140 is to reduce the working voltage output by the target power rail, and specifically includes the following steps:
and S142A, when the load correspondingly connected with the target power supply rail is a secondary load, adjusting the working voltage output by the target power supply rail to be zero.
It can be understood that, for the target power rail connected to the secondary load, the voltage regulation strategy is to regulate the operating voltage output by the target power rail to zero, so that the secondary load is in a shutdown state. That is, when the battery supply voltage is in a low state, to prolong the endurance time of the device, the output of the operating voltage to the secondary load is stopped, so that the secondary load stops operating, and the purpose of saving power is achieved.
Illustratively, the method of the embodiment of the present invention further includes: and adjusting at least one of the first voltage threshold and the second voltage threshold according to the endurance requirement of the electronic equipment.
It can be understood that, in the embodiment of the present invention, the voltage threshold of each power rail may be dynamically adjusted according to the endurance requirement of the device, and specifically, the voltage threshold may be appropriately increased for the endurance requirement that the endurance time is required to be further extended. For example, the endurance demand is divided into two grades according to the endurance time of 10 days and 15 days. For the endurance requirement of 10 days of endurance, the first voltage threshold is 3.3V, and the second voltage threshold is 4V; for a cruising demand of 15 days, the first voltage threshold is 3.5V, and the second voltage threshold is 4.5V. It should be appreciated that after adjusting the first voltage threshold and/or the second voltage threshold, the first voltage threshold should still be less than the second voltage threshold.
It can be understood that the endurance requirement of the device may be set by a user, for example, through an application interface of the mobile terminal, the mobile terminal sends an instruction carrying the endurance requirement of the user to the electronic device according to the embodiment of the present invention through a bluetooth or other wireless signal, and the electronic device sets the voltage threshold of the power rail according to the received endurance requirement instruction. In addition, a function key can be arranged on the electronic equipment, so that a user can set a cruising demand through the function key.
In order to facilitate a better understanding of the aspects of the embodiments of the invention, reference will now be made to specific examples.

When detecting that the power supply voltage output by the battery module is less than 4V, the working voltages output by the power supply rails #2 and #4 are regulated to be zero, so that the sensor 14b and the indicator lamp 14d stop working, and the endurance time is prolonged. As the supply voltage output by the battery module continues to decrease, when it is detected that the supply voltage output by the battery module is less than 3.3V, the operating voltages output by the power rails #1 and #3 are adjusted to the corresponding target operating voltages, so that the memory 14a and the encryption chip 14c operate at the lowest operating voltages, respectively.

when the load correspondingly connected with the target power supply rail is an important load, determining a target working voltage corresponding to the important load;
and regulating the working voltage output by the target power supply rail from the initial working voltage to the target working voltage to enable the important load to be in a low-power-consumption working state, wherein the target working voltage is less than the initial working voltage.
It is to be understood that the voltage regulation module 24 may be further specifically configured to:
