Technical Field

Background

At present, a rechargeable lithium ion battery is generally used as a power supply for terminal equipment such as a mobile phone, and the lithium ion battery needs to be charged by a charger. At present, most of lithium battery chargers adopt various special control Integrated Circuits (ICs) and various sampling circuits. Most of the current universal lithium battery chargers adopt a bipolar operational amplifier (such as LM358) to control a discrete device PNP (such as S8550) to perform voltage-limiting charging on the lithium battery, and in the charging process, along with the rise of the voltage of a charged battery, the charging current of the battery is continuously reduced until the voltage of the charged battery reaches a set value (generally, the nominal value is 4.2V), and at the moment, the charging voltage keeps unchanged to maintain small current charging and discharging, so that the battery is balanced.

However, in some cases, the charging time of the terminal device becomes long due to the presence of a load on the electronic device or the lack of power of the charger. Therefore, poor product use experience is brought to users. How to increase the charging speed of the battery and shorten the charging time becomes a problem that technicians pay more attention to.

The units may communicate by way of local and/or remote processes such as in accordance with a signal having one or more data packets (e.g., from a second unit of data interacting with another unit in a local system, distributed system, and/or across a network.

The charging process of the lithium ion battery is mainly divided into three stages: a pre-charging stage, a constant current charging stage and a constant voltage charging stage. The basic requirements of a lithium battery charger are a specific charging current and charging voltage in order to ensure safe charging of the battery. In addition, other charging auxiliary functions can be added to prolong the service life of the battery and simplify the operation of the charger. Wherein the auxiliary functions may include: low current charging for over-discharged batteries, battery voltage detection, input current limiting, shutting down the charger after charging is complete, automatic start of charging after partial discharge of the battery, etc.

The charging mode of the lithium battery is voltage-limiting constant current and is controlled by an IC chip, and the common charging mode is as follows: the voltage of the battery to be charged is detected, and if the voltage of the battery is lower than the pre-charging voltage threshold Vpre, pre-charging is performed first, and the pre-charging current Ipre can be set to be a constant charging current Iv. After the voltage of the battery rises to the pre-charge voltage threshold V1, the constant current charging phase is entered. The charging process in the constant current charging stage is as follows: and charging the battery by setting Iv, and entering a constant voltage charging stage when the battery voltage rises to a set voltage threshold value Vc to keep the charging voltage Vc. At this time, the charging current flowing in the battery gradually decreases, and when the current decreases to I1, the charging ends.

Next, three stages of the lithium battery will be described in detail with reference to fig. 1A.

And at the time t 1-t 2, the lithium battery is in a pre-charging stage. The charging phase is the restorative charging of the fully discharged battery cells. When the battery voltage is lower than the precharge voltage threshold V1, the battery is charged by the precharge current Ipre. Wherein Ipre may be determined based on the constant current Iv set for the constant current charging phase. For example, in the constant current charging phase, Iv is 1A, and Ipre may take one tenth of Iv, that is, in the pre-charging phase, the battery may be charged with a constant current of 100 mA. During the pre-charging phase, the charging voltage of the battery is increased continuously, and when the charging voltage of the battery is greater than or equal to the set V1, the constant current charging phase is entered.

And at the time t 2-t 3, the charging stage of the lithium battery is a constant current charging stage. In the constant current charging stage, the charging current of the battery is preset Iv, and the voltage of the battery is gradually increased along with the constant current charging process. The constant current charging stage is a main stage of increasing the electric quantity of the battery and is also a stage of fastest charging energy of the battery, and the current value of the charging current required by the battery is the largest in the constant current charging stage. When the voltage of the battery reaches a preset full-voltage Vc, entering a constant-voltage charging stage.

And at the time t 3-t 4, the charging stage of the lithium battery is a constant-voltage charging stage. In the constant voltage charging phase, the charging voltage of the battery is kept constant and is preset Vc. The charging current is based on the saturation degree of the battery cell, the charging current is slowly reduced from Iv as the charging process continues, and the charging is terminated when the current value of the charging current is reduced to I1.

However, the user can use the terminal device during the charging process of the electronic device to ensure the use requirement. Such as making a phone call, watching a video, messaging, etc. during charging. This makes it necessary to supply a part of the charging current to the peripheral device or Micro Control Unit (MCU) of the terminal device during the charging process to ensure the proper operation of these hardware. This means that, in the constant current charging phase, the charging current does not reach the preset Iv, and the charge of the battery increases slowly, thereby prolonging the charging time. As shown in fig. 1B, in the constant current charging phase, the charging current flowing to the battery is less than Iv, and the time of the constant current charging phase is prolonged to the time t5 (t 5 is greater than t 3), so that the charging time of the battery is prolonged.

In another case, the power of the power supply connected to the charger itself is insufficient, so that the charging current of the battery is difficult to reach the preset constant current in the constant current stage of charging the battery, thereby reducing the charging speed and prolonging the charging time. For example, as shown in fig. 2A-2B, there are two charging modes for smart watch 101. The first way is to connect the smart watch 101 to a power outlet through the charger 102 for charging. The second way is to connect the smart watch 101 to the USB interface 103 of the socket for charging. Since the power supply provided by the USB interface 103 of the receptacle is small, the charging time for the smart watch 101 in the second manner is longer than the charging time in the first manner.

The charging method aims to solve the problems that in the battery charging process, due to the fact that an application program of the electronic equipment and/or a related peripheral device runs, a charging current is partially shunted to the MCU and/or the peripheral device, and therefore in the constant current charging stage, the current value of the charging current flowing into the battery does not reach a preset value, the electric quantity of the battery is slowly increased, and the charging time is prolonged. The application provides a charging method: in the charging process, the electronic equipment dynamically detects the magnitude of the charging current, and in the constant-current charging stage, under the condition that the charging current of the battery does not reach a preset value, the working modes of partial peripheral devices are adjusted, so that the charging current flowing into the partial peripheral devices is reduced, the charging current flowing to the battery is increased, and the charging efficiency is improved.

Next, a system architecture of the charging method according to the embodiment of the present application is described with reference to fig. 3. Referring to fig. 3, fig. 3 is a system framework diagram of a charging method according to an embodiment of the present disclosure. As shown in fig. 3, the system framework includes a current management module, a battery, peripheral devices (only 5 peripheral devices are listed in fig. 3, and it is assumed that the peripheral devices 1 to 5 are all running peripheral devices), a power consumption adjustment module, and an MCU. The application programs 1 to 5 deployed on the MCU are running application programs, and the application programs 1 to 5 are respectively associated with the peripheral devices 1 to 5. When the application 1 is running, the peripheral device 1 is also running. When the application 2 is running, the peripheral device 2 is also running. When the application 3 is running, the peripheral device 3 is also running. When the application 4 is running, the peripheral device 4 is also running. When the application 5 is running, the peripheral device 5 is also running. The current management module is used for distributing the charging current Ig, and the power consumption adjusting module is used for reducing the power consumption of the peripheral device/MCU. During the charging process, the working process of the system is as follows:

the current management module distributes a part of current Is of the Ig to the MCU of the electronic equipment and the running peripheral devices so as to ensure that the peripheral devices and the MCU can work normally. The power management module distributes another portion of the charging current I2 to the battery for battery charging. During the charging process, the power consumption adjusting module periodically detects the charging current I2 flowing into the battery. In the constant current charging stage, after the power consumption adjusting module detects I2 flowing into the battery, the power consumption adjusting module compares I2 with a preset current Iv to determine whether I2 is greater than or equal to Iv. If I2 is greater than or equal to Iv, the power consumption adjusting module does not adjust the power consumption of the MCU and the related peripheral devices. If I2 is smaller than Iv, the power consumption adjusting module will reduce the power consumption of the related peripheral devices or MCU, so as to increase I2 and shorten the charging time.

The following describes a flow of a charging method provided in an embodiment of the present application in detail with reference to specific embodiments. Referring to fig. 4, fig. 4 is a flowchart of a charging method provided in the embodiment of the present application, and the specific flow is as follows:

step S401: precharging the battery with a first constant current in response to a first operation; during the pre-charging process, the battery voltage is a first voltage, and the first voltage is smaller than a first voltage threshold value.

Specifically, in the process of pre-charging the battery, the charging current of the battery is a constant current, and the current is a first constant current. Illustratively, the first constant current may be Ipre in the embodiment of fig. 1A described above. During the pre-charging process, the voltage of the battery continuously rises along with the increase of the charging time, but is always smaller than a voltage threshold value, and the voltage threshold value is a first voltage threshold value. The first voltage threshold may be obtained based on an empirical value, may also be obtained based on historical data, and may also be obtained based on experimental data, which is not limited in the embodiment of the present application. Illustratively, the first voltage threshold may be V1 in the embodiment of fig. 1A described above.

Step S402: and charging the battery at a second constant current when the voltage of the battery is greater than or equal to the first voltage threshold.

Specifically, in the pre-charging phase, the voltage of the battery is increased along with the increase of the charging time, and when the voltage of the battery is greater than or equal to the first voltage threshold, the battery enters the constant-current charging phase in the embodiment of fig. 1A. And the electronic equipment charges the battery at a second constant current, and the voltage of the battery is continuously increased but is smaller than a second voltage threshold value in the constant current charging stage. The second voltage threshold may be obtained based on an empirical value, historical data, or experimental data, and the embodiment of the present application is not limited. Illustratively, the second voltage threshold may be Vc in the embodiment of fig. 1A described above.

Step S403: and under the condition that the second constant current is smaller than the first current threshold, adjusting the working mode of the target peripheral device.

Specifically, the first current threshold may be obtained based on an empirical value, may also be obtained based on historical data, and may also be obtained based on experimental data, which is not limited in the embodiment of the present application. Illustratively, the first current threshold may be Iv in fig. 1A, described above. Adjusting the working mode of the target peripheral device can be understood as adjusting the target peripheral device from a normal working mode to a low power consumption mode; or, the current flowing to the target peripheral device is reduced, so that the current flowing to the target peripheral device is smaller than the current consumed in the normal working mode and larger than the current consumed in the low power consumption mode. In the charging process of the electronic device, the distribution of the charging current mainly has the following two conditions:

in the first case: the electronic equipment does not have any application program or peripheral device to operate in the charging process, namely: the peripheral devices and/or the MCU of the electronic device do not consume current. At this time, almost all of the charging current of the electronic device flows to the battery. The peripheral devices of the electronic device may be hardware devices such as a bluetooth chip, a chip for controlling a screen, and an image processor of the electronic device. Applications of the electronic device are deployed on the MUC, and the MCU needs to consume current when there is an application running.

In the second case: the electronic equipment has running application programs or peripheral devices in the charging process. The MCU of the electronic device and the associated peripheral devices then consume current. At this time, the charging current flowing into the electronic device Is mainly divided into two parts, the first part Is the current Is flowing into the peripheral device and/or the MCU, and Is used to maintain the normal operation of the peripheral device and/or the MCU. The second part is the current I2 flowing into the battery for increasing the charge of the battery to charge the battery.

Therefore, after the electronic device enters the constant current charging stage, the electronic device detects the magnitude of the second constant current and compares the magnitude of the second constant current with the magnitude of the first current threshold. If the second constant current is smaller than the first current threshold, the electronic device may adjust the operating mode of the target peripheral device according to a difference between the second constant current and the first current threshold, reduce the charging current flowing to the target peripheral device, and increase the charging current flowing to the battery, thereby shortening the charging time of the battery.

In some embodiments, the electronic device may determine the target peripheral device and adjust the operating mode of the target peripheral device through a built-in peripheral device power consumption information table. For example, the peripheral device power consumption information table may be as shown in table 1:

TABLE 1

In table 1, the GPS chip, the PPG, the screen, and the bluetooth chip are peripheral devices of the electronic device, and in the normal operating mode, the power consumptions are respectively 15mA, 8mA, 35mA, and 10mA, and in the low power consumption mode, the power consumptions are respectively 10mA, 3mA, 28mA, and 5 mA. Where low power consumption may be understood as sacrificing some of the performance of the peripheral device such that the current consumed by the peripheral device is reduced. For example, reducing the power consumption of the screen may be understood as reducing the brightness, refresh rate, and the like of the screen, and reducing the power consumption of the bluetooth chip may be understood as reducing the operating frequency of the bluetooth chip, and the like. The electronic device may determine the target peripheral device based on the difference between I2 and the first current threshold and reduce the current consumed by the peripheral device, thereby bringing I2 close to the first current threshold and reducing the charging time of the battery.

For example, the electronic device detects that I2 is 85mA and the first current threshold Iv is 100 mA. Then the current difference between I2 and Iv is 15 mA. The electronic equipment can determine that the three peripheral devices including the GPS chip, the PPG sensor and the Bluetooth chip are target devices, and the working modes of the GPS chip, the PPG sensor and the Bluetooth chip are adjusted to be low-power-consumption modes, so that the working currents consumed by the Bluetooth chip, the GPS chip and the PPG sensor are reduced, and the reduced working currents flow to the battery. For example, after the electronic device adjusts the operating modes of the three peripheral devices, namely the GPS chip, the PPG sensor, and the bluetooth chip, to the low power consumption mode, the current consumption of the three peripheral devices, namely the GPS chip, the PPG sensor, and the bluetooth chip, is respectively changed from 15mA to 10mA, from 8mA to 3mA, and from 10mA to 5 mA. Thus, I2 was increased by 15mA to 100mA, which was the same as Iv. Thus, the charging time of the battery is greatly reduced in the constant current charging stage.

In a possible implementation manner, the electronic device may dynamically update the power consumption information table of the peripheral device, and then select M peripheral devices with the priority ranking of the top M as target peripheral devices according to the priority ranking in the power consumption information table of the peripheral device according to the difference Ix between the second constant current and the first current threshold, thereby adjusting the operating mode of the peripheral devices. And the sum of the difference values of the current consumed by the selected target peripheral device under the normal operation and the current consumed after the operation mode is adjusted is equal to Ix. Or the sum of the difference values of the current consumed by the selected target peripheral device under the normal operation and the current consumed after the operation mode is adjusted is smaller than and closest to Ix.

The first peripheral device and the second peripheral device may be included in the peripheral device power consumption information table. The first peripheral device is a peripheral device which is currently working and is associated with the application program running in the foreground, and the second peripheral device is a peripheral device which is currently running and is not associated with the application program running in the foreground. For example, the application programs running in the electronic equipment comprise applications 1 to 10, and the applications 1 to 10 are respectively associated with the devices 1 to 10. Suppose that the devices 1 to 10 are currently started peripheral devices, the application 1 is an application program running in the foreground, and the applications 2 to 10 are application programs running in the background. Then, the first peripheral device is the device 1, and the devices 2 to 10 are second peripheral devices. Because the first peripheral device is a peripheral device associated with the application program currently running in the foreground, the target peripheral device cannot be determined in the first peripheral device, and the target peripheral device cannot be determined in the second peripheral device, so that the use effect of the foreground application program is not influenced.

The electronic equipment can sort the priority of the peripheral devices in the second peripheral devices, so that the electronic equipment can select the peripheral device with high priority from the second peripheral devices as a target peripheral device according to the difference value between the second constant current and the first current threshold. The electronic device may prioritize the peripheral devices in the second peripheral device based on two methods:

in a first method, the electronic device may determine the priority of the peripheral device based on a difference between a current consumed by the peripheral device in the normal operating mode and a current consumed by the peripheral device in the low power consumption mode. The larger the difference, the more advanced the priority ranking of the peripheral device in the second peripheral device, the easier it is to determine the target peripheral device.

Referring to table 2, table 2 is an exemplary power consumption information table of the second peripheral device (device 2 to device 10), and table 2 is as follows:

TABLE 2

As shown in table 2, the power consumptions of the devices 2 to 10 in the normal operation mode are 56, 79, 24, 33, 72, 44, 58, 61, and 22, respectively, and the power consumptions of the devices 2 to 10 in the low power consumption mode are 51, 68, 22, 27, 60, 40, 50, 54, and 21, respectively. Therefore, the difference between the current consumed by the devices 2 to 10 in the normal operation mode and the current consumed in the low power consumption mode is 5, 11, 2, 6, 12, 4, 8, 7 and 1, respectively. The devices 2-10 are sorted from front to back according to the priority as follows: device 6> device 3> device 8> device 9> device 5> device 2> device 7> device 4> device 10. Assuming that the second constant current currently charging the battery is 80mA, if the first current threshold Iv is 100mA, Ix is 20 mA. Then, the electronic apparatus may select the peripheral devices (device 6 and device 3) of the top priority 2 as the target peripheral devices, adjust the device 6 to the low power consumption mode, and adjust the current flowing to the device 3 to 71mA, so that the current decreasing to the device 6 and the device 3 coincides with Ix. By the mode, the number of the target peripheral devices determined by the electronic equipment is as small as possible, and the use experience of a user is improved. It should be noted that, after the electronic device adjusts the operation mode of the target peripheral device, the current flowing to the target peripheral device should be not less than the current value consumed in the low power consumption operation mode. For example, the device 6 is a target peripheral device, and when the electronic device adjusts the operating mode of the device 6, the current flowing into the device 6 should be ensured to be in the range of 60 mA-72 mA.

The second method comprises the following steps: the electronic device may prioritize the peripheral devices in the second peripheral device according to the number of currently running applications associated with the peripheral devices in the second peripheral device. The more peripheral devices associated with an application, the lower their priority, i.e.: the less easily it is determined to be the target peripheral device. The application program associated with the peripheral device may be understood as the peripheral device that the application program can use in the using process. For example, a piece of music software is associated with at least three peripheral devices, including a screen (display interface), a speaker, and a GPS chip (currently, most music applications have positioning functions). As shown in table 3, for another exemplary power consumption information table of the second external device provided in the embodiment of the present application, table 3 is as follows:

TABLE 3

As shown in Table 3, the number of running applications associated with devices 2-10 are: 3. 5, 6, 2, 1, 7, 4, 5. The devices 2-10 are sorted from front to back according to the priority as follows: device 6> device 5> device 2> device 8, device 9> device 3, device 10> device 4> device 7. Assuming that the second constant current currently charging the battery is 80mA, if the first current threshold Iv is 100mA, Ix is 20 mA. Then, the electronic device may select the device 6, the device 5, and the device 2 with the top priority 3 as target peripheral devices, and adjust the operating modes of the 3 peripheral devices, so that the operating modes of the device 6 and the device 5 are low power consumption operating modes, and the current flowing into the device 2 is reduced to 54mA, so that the current reduced to the device 6, the device 5, and the device 2 is consistent with Ix. It should be noted that, after the electronic device adjusts the operation mode of the target peripheral device, the current flowing to the target peripheral device should be not less than the current value consumed in the low power consumption operation mode. For example, the device 6 is a target peripheral device, and when the electronic device adjusts the operating mode of the device 6, the current flowing into the device 6 should be ensured to be in the range of 60 mA-72 mA.

In some embodiments, after adjusting the operating mode of the target peripheral device, the electronic device may switch the application currently running in the foreground to the first application in response to a first input operation by the user. Then, the electronic equipment updates the power consumption information table of the peripheral device, and the specific mode is as follows: and determining the peripheral device associated with the first application program as a first peripheral device, determining the running peripheral device which is not associated with the first application program as a second peripheral device, and sequencing the peripheral devices in the second peripheral device according to the two methods. The electronic device then adjusts the operating mode of the peripheral device associated with the first application to a normal operating mode. Thus, the current flowing to the peripheral device is increased, so that the second constant current becomes smaller. Therefore, the electronic device may calculate a difference Ix between the current second constant current and the first current threshold, determine, according to Ix, the peripheral device with the priority level of the front L as the peripheral device to be adjusted in the second peripheral device, and adjust the working mode of the peripheral device to be adjusted to reduce the current flowing to the L peripheral devices, so that the reduced current is equal to Ix.

In some embodiments, the electronic device may determine the target application and the target peripheral device according to the application power consumption information table, and adjust the operating modes of the target application and the target peripheral device to the low power consumption mode, thereby implementing the increase I2. For example, the application power consumption information table may be as shown in table 4:

TABLE 4

The electronic equipment can carry out priority classification on the application program running on the MCU, thereby carrying out targeted adjustment on the power consumption of the target application program or the target peripheral device. For example, the electronic device may set a power consumption adjustment whitelist, which is divided into a primary application, a secondary application, and a tertiary application. The first-level application program is an application program which runs in the background and has the duration less than or equal to a first time threshold, the second-level application program is an application program which runs in the background and has the duration greater than the first time threshold, and the third-level application program is an application program which runs in the foreground, wherein the priority order of the first-level application program, the second-level application program and the third-level application program is as follows: primary application > secondary application > tertiary application. The application programs in the application program power consumption information table include a first application program and a second application program. The first application program is an application program which does not start the peripheral device when running. And the second application program is an application program which starts the corresponding peripheral device when running. The current value consumed by the second application program in the normal working mode comprises the current value consumed by the peripheral device corresponding to the second application program in the normal working mode, and the current value consumed by the second application program in the low power consumption mode comprises the current value consumed by the peripheral device corresponding to the second application program in the low power consumption mode. For example, in table 4, application 1, application 3, and application 4 are the second application program, the power consumption of application 1 in the normal operation mode and the low power consumption mode is 30mA and 25mA, respectively, and the power consumption of device 1 is also included in 30mA and 25 mA.

In each level of application program, the priority is determined according to the difference between the current of the application program and the relevant peripheral device in the normal working mode and the current of the application program and the relevant peripheral device in the low power consumption mode, the application program with high difference and the peripheral device with high difference have high priority, and the application program with low difference and the relevant peripheral device with low difference have low priority. When the electronic device detects that I2 is less than or equal to the first current threshold Iv, the electronic device may adjust power consumption of an application in the primary application and an operating mode of a peripheral device corresponding to the application to reduce a charging current flowing to the MCU and the peripheral device. If the electronic equipment detects that the I2 is smaller than the Iv after the adjustment, the electronic equipment adjusts the application power consumption in the secondary application and the power consumption of the peripheral device corresponding to the application according to the priority, so as to increase the I2. Because the third-level application is an application program currently running in the foreground, the electronic device does not adjust the working mode of the application program in the third-level application and the working mode of the corresponding peripheral device. If the electronic device adjusts the operation modes of all the application programs in the secondary application and the primary application to the low power consumption mode, I2 is still less than Iv. Then the electronic device may start with the primary application, sequentially clean the application and close the peripheral devices associated with the application according to the priority until I2 is greater than or equal to Iv. If all the application programs and the related peripheral devices in the primary application and the secondary application are closed, I2 is still smaller than Iv, and the electronic device does not perform any processing any more.

The above process will be described with reference to table 4. In table 4 above, 10 applications of the electronic device are listed. Application 1, application 5, and application 6 are two-level applications with priorities of application 6> application 5> application 1. The application 2, the application 3, the application 4, the application 7, the application 8, the application 9, and the application 10 are first-level applications, and the priorities thereof are: application 4> application 9> application 7> application 2> application 8> application 3> application 10. Wherein, the total power consumption of the application 1 and the device 1 in the normal operation mode is 30mA, and the total power consumption in the low power consumption mode is 25 mA. The total power consumption of the application 3 and the device 2 in the normal operation mode is 8mA, and the total power consumption in the low power consumption mode is 6 mA. The total power consumption of the application 4 and the device 3 in the normal operation mode is 55mA, and the total power consumption in the low power consumption mode is 52 mA. The power consumption of the application 2, the application 5, the application 6, the application 7, the application 8, the application 9 and the application 10 in the normal operation mode is 15mA, 35mA, 40mA, 22mA, 11mA, 26mA and 8mA, respectively, and the power consumption in the low power consumption mode is 10mA, 33mA, 38mA, 20mA, 9mA, 22mA and 5 mA. Assuming that Iv is 150mA and the current I2 is 80mA, then I2 also requires 70mA to reach Iv. The electronic device may first adjust the operation modes of the application programs in the primary application in sequence according to the priorities. After the electronic device adjusts the operating modes of all the application programs in the primary application to the low power consumption mode, I2 is 101 mA. Since I2 is still less than Iv, the electronic device adjusts the operating mode of the application in the secondary application to the low power consumption mode in order of priority. At this time, I2 was 110mA, which was still less than Iv. The electronic equipment can sequentially close the application programs and the peripheral devices thereof in the first-level application according to the priority order, 52mA current flows to the battery after the electronic equipment closes the application 4 and the device 3, and the value of I2 is 162mA and is larger than Iv.

In some embodiments, after the electronic device adjusts the operating mode of the application program or turns off the application program and its peripheral devices, if I2 is greater than Iv, the electronic device may allocate a portion of the current, I2 exceeding Iv, to the application in the low power consumption mode, so that the application in the low power consumption operating mode may return to the normal operating mode. For example, in the above process, I2 is 162mA after the electronic device turns off application 4 and device 3. The current of the part I2 exceeding the Iv is 12mA, and the electronic device can distribute the current of 12mA to the application 1 and the device 1, the application 5, the application 6 and the application 10 in the low power consumption operation mode, so that the application and the peripheral device become the normal operation mode, thereby improving the use experience of the user. The electronic equipment can distribute the current exceeding the Iv part to the application program and the related peripheral devices in the low power consumption operation mode according to the priority. For example, the electronic device may now distribute current to the application program and its peripheral devices at low power consumption in the secondary application according to priority, so that it resumes the normal operating mode. If the distributable current exists after the current distribution to the application programs and the peripheral devices thereof in all the secondary applications is finished, the electronic equipment can distribute the remaining distributable current to the corresponding application programs and the peripheral devices thereof in the primary applications according to the priority order until the current distribution is finished.

Step S404: charging the battery at a third constant current.

Specifically, the third constant current is greater than the second constant current, and in the process of charging with the third constant current, the voltage of the battery is a third voltage, and the third voltage is greater than the second voltage.

In the embodiment of the application, the electronic device detects the charging current I2 flowing into the battery periodically during the charging process of the battery. In the constant current charging stage, the electronic device compares the current value I2 with a preset current value Iv after detecting I2 flowing into the battery. If I2 is greater than or equal to Iv, the electronic device does not adjust the power consumption of the MCU and the associated peripheral devices. If the I2 is smaller than Iv, the electronic device will adjust the operation mode of the relevant application program and the peripheral device thereof to a low power consumption mode, thereby increasing I2 and shortening the charging time.
