The terminal equipment products with rechargeable batteries, such as conference terminals or other mobile terminal products, on the market at present have a scene of charging and using by connecting a power adapter for a long time.

When the charging IC detects a voltage drop of the battery (e.g., a 100 millivolt (mV) drop detected by a single cell and a 200mV drop detected by a double cell), the charging IC automatically initiates a recharge mechanism. However, because the system consumes the battery power, the battery voltage drops by 100mV for a short period of time, the charging IC is frequently activated to recharge the battery, the battery may be in a high potential cyclic charge state for a long period of time, which may result in a shortened battery life and an unpredictable safety hazard for battery use.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, exemplary embodiments according to the present application will be described in detail below with reference to the accompanying drawings. It should be understood that the described embodiments are only some embodiments of the present application and not all embodiments of the present application, and that the present application is not limited by the example embodiments described herein. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the application described in the application without inventive step, shall fall within the scope of protection of the application.
First, a charging method 100 for a terminal device according to an embodiment of the present application is described with reference to fig. 1. As shown in fig. 1, the charging method 100 for a terminal device may include the steps of:
in step S110, after the terminal device is connected to the power adapter, the accumulated time of the terminal device being connected to the power adapter is counted. When the accumulated time is less than or equal to a preset time threshold, executing step S120; when the accumulated time is greater than the preset time threshold, step S130 is performed.
In step S120, the accumulated time is less than or equal to a preset time threshold, and the battery of the terminal device is charged in a first charging mode, where the first charging mode includes: charging the battery whenever the voltage of the battery is less than a first voltage threshold.
In step S130, the accumulated time is greater than a preset time threshold, and the battery is charged in a second charging mode, where the second charging mode includes: charging the battery whenever the voltage of the battery is less than a second voltage threshold, wherein the second voltage threshold is less than the first voltage threshold.
In the embodiment of the present application, the mode of charging the battery of the terminal device is determined according to whether the terminal device is connected to the power adapter for a long time. Specifically, whether the power adapter is connected for a long time or not may be determined by setting a time threshold value and comparing the cumulative time for the terminal device to connect the power adapter with the time threshold value. If the cumulative time for which the terminal device is connected to the power adapter is less than or equal to the time threshold, the terminal device is considered not to be in a state of being connected to the power adapter for a long time, and the battery of the terminal device is charged in the first charging mode (so named for distinguishing from the second charging mode hereinafter). Specifically, the first charging mode may be a mode in which: the voltage of the battery is monitored and the battery is charged when the battery voltage is less than a first voltage threshold (so named for distinguishing from a second voltage threshold hereinafter). After the battery is charged, the voltage of the battery is reduced due to loss of the terminal equipment and the like, the voltage of the battery can be continuously monitored, and when the voltage of the battery is smaller than the first voltage threshold value again, the battery is charged (recharged), and the process is repeated. Meanwhile, in the above process, the accumulated time of the terminal device connecting with the power adapter is kept to be timed, when the accumulated time of the terminal device connecting with the power adapter is greater than the time threshold, the terminal device is considered to be in a state of connecting with the power adapter for a long time, and at this time, the second charging mode is started, and the battery of the terminal device is charged in the second charging mode. Specifically, the second charging mode may be a mode in which: and monitoring the voltage of the battery, and charging the battery when the voltage of the battery is less than a second voltage threshold value. After the battery is charged, the voltage of the battery is reduced due to loss of the terminal equipment and the like, the voltage of the battery can be continuously monitored, and when the voltage of the battery is smaller than the second voltage threshold value again, the battery is charged again, and the process is circulated. In the embodiment of the present application, the second voltage threshold is smaller than the first voltage threshold, that is, in the second charging mode, charging of the battery is started only when the battery voltage drops to a smaller value compared to the first charging mode. The method can solve the problems that the battery is in a high potential cyclic charging state for a long time, the service life of the battery is influenced and potential safety hazards are brought because the battery voltage is started to be recharged after the battery voltage is rapidly reduced due to energy consumption of the terminal equipment in a short time. After the terminal equipment is judged to be connected to the power adapter for a long time, the first charging mode is stopped to charge the battery in the second charging mode, and the second charging mode starts charging after the voltage of the battery is reduced to a smaller value, so that the cyclic charging at a lower potential is realized, and the number of times of the high-potential cyclic charging of the battery can be greatly reduced. That is to say, the first charging mode of the present application may be regarded as a charging mode when the terminal device is connected to the power adapter for a short period of time, and the second charging mode may be regarded as a long-term charging protection mode when the terminal device is connected to the power adapter for a long period of time.
In embodiments of the present application, when charging the battery in the first charging mode, the charging may be stopped when the battery is charged to full capacity (e.g., from the first voltage threshold to the full capacity voltage value). Further, when the battery is charged in the second charging mode, the charging may be stopped when the battery is fully charged (for example, when the battery is charged from the second voltage threshold to the full charge voltage value), or the charging may be stopped when the battery is charged to the first voltage threshold (that is, when the battery is charged from the second voltage threshold to the first voltage threshold).
In the embodiment of the application, after the battery of the terminal device is charged in the second charging mode, when the disconnection between the terminal device and the power adapter is detected, the second charging mode is exited, and the accumulated time of the connection of the terminal device to the power adapter is cleared; and when the fact that the terminal equipment is connected with the power adapter again is detected, starting the first charging mode and restarting timing. Generally, when the terminal device is just connected to the power adapter, the accumulated time for connecting the terminal device to the power adapter is not immediately greater than the set time threshold, so the first charging mode can be generally started first; and when the timing time exceeds a set time threshold value in the connection state, starting the long-time charging protection mode, namely a second charging mode.
In the embodiment of the application, when the terminal equipment is identified to be in a state of being connected with the power adapter for a long time, the terminal equipment can be triggered to enter a long-time charging protection mode, and then prompt information is sent to remind a user that the condition that the battery is in long-time high-potential charging is detected, and the battery is stopped to be charged at the high potential. Or, the prompt information may be sent first, and after the user confirms the prompt information, the device is triggered to enter the long-time charging protection mode. This can provide more flexible charging mode for the user, satisfies user's different demands.
In the embodiment of the present application, the aforementioned time threshold may be set by default, or may be set by a user in a customized manner. In one example, the time threshold may be 48 hours. That is, when the cumulative time that the terminal device is connected to the power adapter exceeds 48 hours, the device is considered to be in a use state of the long-term connection power adapter, triggering the device to enter the long-term charge protection mode. In the embodiment of the present application, the first voltage threshold and/or the second voltage threshold may be set by default or by user-defined settings. In one example, the first voltage threshold may be 4.1 volts (V), the second voltage threshold may be 3.6V, and the voltage value for full power may be 4.2V. In the embodiment of the present application, the terminal device may be a conference terminal or other terminal devices, and the battery of the terminal device may be a lithium battery or other rechargeable batteries.
A more specific flow of the charging method for the terminal device according to the embodiment of the present application is described below with reference to fig. 2 by taking the above threshold as an example. As shown in fig. 2, the power adapter plug-in enables charging software (i.e. software for the charging method of the terminal device according to the embodiment of the present application) starts a charging timer, and stops charging when the terminal device is charged to full 4.2V; after discharging to 4.1V, recharging is started. If the accumulated time is not more than 48 hours, determining whether the power adapter is pulled out, if so, resetting the timer, and restarting timing after the power adapter is inserted; if the mobile phone is not pulled out, when the accumulated time is longer than 48 hours, the software closes the charging enable, prompts a user to enter high-potential charging protection, namely, the charging is enabled again after discharging to 3.6V, the enabling is closed after charging to 4.1V, and the charging is stopped, thus the cycle is repeated.
Based on the above description, according to the charging method for the terminal device in the embodiment of the application, when the terminal device is connected to the power adapter for a long time, the battery of the terminal device is charged in the long-term charging protection mode, so that high-potential cyclic charging of the battery is avoided, the frequency of frequent charging and discharging of the battery can be effectively reduced, the service life of the battery is prolonged, and potential safety hazards are reduced or even avoided.
A terminal device provided according to another aspect of the present application, which may be used to perform the aforementioned charging method for a terminal device according to an embodiment of the present application, is described below with reference to fig. 3. As shown in fig. 3, a schematic block diagram of a mobile terminal 300 according to an embodiment of the present application is shown. As shown, the mobile terminal 300 may include a rechargeable battery 310, a charging integrated circuit chip 320, and a processor 330, wherein the processor 330 is configured to: after the terminal equipment is connected to the power adapter, timing the accumulated time of the terminal equipment connected to the power adapter; when the accumulated time is less than or equal to the predetermined time threshold, the charging integrated circuit chip 320 is controlled to charge the rechargeable battery 310 in a first charging mode, where the first charging mode includes: charging the rechargeable battery 310 whenever the voltage of the rechargeable battery 310 is less than a first voltage threshold; when the accumulated time is greater than the preset time threshold, the charging integrated circuit chip 320 is controlled to charge the rechargeable battery 310 in a second charging mode, where the second charging mode includes: the rechargeable battery 310 is charged whenever the voltage of the rechargeable battery 310 is less than a second voltage threshold, wherein the second voltage threshold is less than the first voltage threshold.
In the embodiment of the present application, the terminal device 300 determines the mode of charging its battery according to whether it is connected to the power adapter for a long time. Specifically, whether the terminal device 300 is connected to the power adapter for a long time may be determined by setting a time threshold and by the processor 330 according to a comparison of an accumulated time that the terminal device 300 is connected to the power adapter, such as an accumulated time that a charging input port (VBUS) is inserted in a bit, with the time threshold. If the cumulative time that the terminal device 300 is connected to the power adapter is less than or equal to the time threshold, it is considered that the terminal device 300 is not in a state of long-term connection to the power adapter, the processor 330 controls the charging integrated circuit chip 320 to charge the rechargeable battery 310 in the first charging mode (so named for distinguishing from the second charging mode hereinafter). Specifically, the first charging mode may be a mode in which: the processor 330 monitors the voltage of the rechargeable battery 310 through the charging integrated circuit chip 320, and when the voltage of the rechargeable battery 310 is less than a first voltage threshold (so named for distinguishing from a second voltage threshold hereinafter), the processor 330 controls the charging integrated circuit chip 320 to charge the rechargeable battery 310. After the rechargeable battery 310 is charged, the voltage of the rechargeable battery 310 may drop due to loss of the terminal device 300, and the processor 330 may continue to monitor the voltage of the rechargeable battery 310 through the charging integrated circuit chip 320, and when the voltage of the rechargeable battery 310 is again less than the first voltage threshold, the processor 330 controls the charging integrated circuit chip 320 to charge (recharge) the rechargeable battery 310 again, and so on. Meanwhile, in the above process, the accumulated time of the terminal device connecting to the power adapter is kept being timed, and when the accumulated time of the terminal device connecting to the power adapter is greater than the time threshold, the terminal device is considered to be in a state of connecting to the power adapter for a long time, and at this time, the charging integrated circuit chip 320 is controlled to start the second charging mode, and the rechargeable battery 310 of the terminal device is charged in the second charging mode. Specifically, the second charging mode may be a mode in which: the voltage of the rechargeable battery 310 is monitored and the rechargeable battery 310 is charged when the voltage of the rechargeable battery 310 is less than a second voltage threshold. After the rechargeable battery 310 is charged, the voltage of the rechargeable battery 310 may drop due to loss of the terminal device, and the voltage of the rechargeable battery 310 may be continuously monitored, and when the voltage of the rechargeable battery 310 is less than the second voltage threshold again, the rechargeable battery 310 may be charged again, and so on. In the embodiment of the present application, the second voltage threshold is smaller than the first voltage threshold, that is, in the second charging mode, charging of the rechargeable battery 310 is not started until the voltage of the rechargeable battery 310 drops to a smaller value, compared to the first charging mode. This can solve the problem that the rechargeable battery 310 is in a high-potential cyclic charging state for a long time, which affects the service life of the rechargeable battery 310 and brings about potential safety hazard, because the rechargeable battery 310 starts recharging after the voltage of the rechargeable battery 310 drops rapidly in a short time due to energy consumption of the terminal device 300. After the terminal device 300 is connected to the power adapter for a long time, the processor 330 controls the charging integrated circuit chip 320 to stop using the first charging mode, and charges the rechargeable battery 310 in the second charging mode, and the second charging mode starts charging after the voltage of the rechargeable battery 310 drops to a smaller value, so as to implement low-potential cyclic charging, thereby greatly reducing the number of times of high-potential cyclic charging of the rechargeable battery 310. That is to say, the first charging mode in the present application may be regarded as a charging mode when the terminal device is connected to the power adapter for a short period of time, and the second charging mode may be regarded as a long-term charging protection mode when the terminal device is connected to the power adapter for a long period of time, in which protection mode, the rechargeable battery 310 is not subjected to high-potential cyclic charging, the number of frequent charging and discharging of the rechargeable battery 310 can be effectively reduced, the service life of the rechargeable battery 310 is prolonged, and potential safety hazards are reduced or even avoided.
In an embodiment of the present application, when the rechargeable battery 310 is charged in the first charging mode, the processor 330 may control the charging integrated circuit chip 320 to stop charging when the rechargeable battery 310 is fully charged (e.g., from the first voltage threshold to the full charge voltage value). In addition, when the rechargeable battery 310 is charged in the second charging mode, the processor 330 may control the charging integrated circuit chip 320 to stop charging when the rechargeable battery 310 is fully charged (e.g., to charge from the second voltage threshold to the full charge voltage value), or may stop charging when the rechargeable battery 310 is charged to the first voltage threshold (e.g., to charge from the second voltage threshold to the first voltage threshold).
In the embodiment of the present application, after the battery of the terminal device is charged in the second charging mode, when it is detected that the terminal device is disconnected from the power adapter, the processor 330 controls the charging integrated circuit chip 320 to exit the second charging mode, and simultaneously clears the accumulated time for connecting the terminal device 300 to the power adapter; upon detecting that the terminal device is reconnected to the power adapter, the processor 330 controls the charging integrated circuit chip 320 to start the first charging mode and restart the timing. Generally, when the terminal device 300 is just connected to the power adapter, the accumulated time for connecting to the power adapter is not immediately greater than the set time threshold, so the first charging mode may be generally started first; and when the timing time exceeds a set time threshold value in the connection state, starting the long-time charging protection mode, namely a second charging mode.
In the embodiment of the present application, when it is recognized that the terminal device 300 is in a state of being connected to the power adapter for a long time, the processor 330 may trigger the device to enter a long-time charging protection mode, and then send out a prompt message (for example, via an output device such as a display screen or a speaker of the terminal device) to remind a user that the rechargeable battery 310 is charged at a high potential for a long time, and the charging of the rechargeable battery 310 at the high potential will be stopped. Alternatively, the processor 330 may also send out the prompt message first, and then trigger the device to enter the long-time charging protection mode after the user confirms the prompt message. This can provide more flexible charging mode for the user, satisfies user's different demands.
In the embodiment of the present application, the aforementioned time threshold may be set by default, or may be set by a user in a customized manner. In one example, the time threshold may be 48 hours. That is, when the cumulative time that the terminal device 300 is connected to the power adapter exceeds 48 hours, the device is considered to be in a use state of the long-term connection power adapter, triggering the device to enter the long-term charge protection mode. In the embodiment of the present application, the first voltage threshold and/or the second voltage threshold may be set by default or by user-defined settings. In one example, the first voltage threshold may be 4.1 volts (V), the second voltage threshold may be 3.6V, and the voltage value for full power may be 4.2V. In the embodiment of the present application, the terminal device may be a conference terminal or other terminal devices, and the battery of the terminal device may be a lithium battery or other rechargeable batteries.
The following describes a charging flow of the terminal device according to an embodiment of the present application, taking the above threshold as an example. The terminal device 300 is connected with a power adapter, the charging input port (VBUS) enables charging, and the charging is stopped after the terminal device is charged to 4.2V full. Because the system consumes the battery power, when the voltage of the rechargeable battery 310 drops to 4.1V, the charging ic chip 320 starts recharging rapidly, so that the charging and discharging cycle is performed between 4.1V and 4.2V. The processor 330 (charging software on) detects the VBUS insertion time through a timer, and when it is detected that the VBUS accumulation time in place exceeds 48 hours (the accumulation time is cleared when a USB event is dialed out), it recognizes that the device is in a long-term connection adapter use state, triggers the device to enter a long-term charging protection mode, and the system may pop a frame to remind the user device that the battery is in a long-term high-potential charging condition, and the device will stop charging the rechargeable battery 310. Only when the rechargeable battery 310 is lowered to a suitable level (for example, the battery voltage is set to be less than 3.6V), the processor 330 will re-enable the charging, set the full charge voltage to 4.1V, and start the cyclic charging before 3.6V to 4.1V. This greatly reduces the number of high-potential cycle charging of the battery. Exiting the long-term charging protection mode requires detecting that the power adapter is unplugged, starting the first charging mode after reinsertion, and entering the long-term charging protection mode when the accumulated time exceeds a time threshold.
Based on the above description, when the terminal device according to the embodiment of the application is connected to the power adapter for a long time, the battery is charged in the long-term charging protection mode, high-potential cyclic charging of the battery is avoided, the frequency of frequent charging and discharging of the battery can be effectively reduced, the service life of the battery is prolonged, and potential safety hazards are reduced or even avoided.
