Detailed Description
In order to make the objects, features and advantages of the present application more comprehensible, the technical solutions in the embodiments of the present application will be clearly described in conjunction with the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
In order to solve the problem of permanent damage to battery capacity caused by overdischarge of a battery in the related art, an embodiment of the present application provides a battery leakage protection method, as shown in fig. 1, which is a first basic flowchart of the battery leakage protection method provided in the present embodiment, where the battery leakage protection method includes the following steps:
step 110, detecting the current residual capacity of the target battery;
specifically, the target battery includes, but is not limited to, a lithium battery, etc., and the remaining power of the target battery is an important criterion for determining the current performance of the target terminal (e.g., mobile phone) corresponding to the target battery, for example, in practical application, most mobile phones default to a mode of starting a low power mode with a power of less than 20% and a super power saving mode with a power of less than 10%, a screen brightness is greatly reduced in the power saving mode, mobile data is automatically closed, and bluetooth is closed. On one hand, the mobile phone with the electric quantity lower than 10% has very low endurance, so that unimportant software functions are reduced for preventing the mobile phone from being suddenly shut down; on the other hand, in order to prevent the mobile phone from overdischarging and affecting the service life of the battery, in this embodiment, the remaining capacity of the target battery is periodically detected, and corresponding protection measures are determined according to the current remaining capacity of the target battery.
Step 120, detecting a discharge voltage of the target battery when the current residual electric quantity is lower than a preset electric quantity threshold value;
specifically, in practical application, when the battery is discharged, the stored electric energy is gradually released, and the voltage is slowly reduced. When the voltage decreases to a certain value, discharging should be stopped and recharging should be performed to restore the energy storage state of the battery. And if the discharge time is lower than the preset value, the discharge is over-discharge, and the over-discharge may cause damage to the electrode active material, lose the reaction capacity and shorten the service life of the battery. Therefore, when the target battery is discharged, the target battery is in a normal discharging state when the stored electric energy is sufficient, and the discharging voltage of the battery is reduced along with the reduction of the electric energy reserve, so that the discharging voltage can be used as the basis of whether the battery is overdischarged or not. Therefore, when the residual electric quantity of the target battery is lower than a preset electric quantity threshold value, the discharging voltage of the target battery is detected, and whether the corresponding target battery is required to be subjected to discharging protection is judged according to the discharging voltage.
And 130, triggering a leakage protection mode of the target battery when the discharge voltage reaches the cut-off voltage.
Specifically, in practical application, the discharge voltage of the lithium ion battery (including the storage battery and other rechargeable batteries) is 0.9 times the rated voltage, and the discharge is considered to be completed. While there is still remaining power, it is not possible to continue use, otherwise the battery may be damaged. Therefore, in this embodiment, a MOS (Metal-Oxide-Semiconductor Field-Effect Transistor), also called MOSFET, is added to the motherboard of the target terminal product, which is a commonly used semiconductor device. The main operating principle of a MOS transistor is to use a control gate voltage to control the flow of current through a channel between two sources and drains, and is therefore also called a Field effect transistor (Field-Effect Transistor, abbreviated FET). I.e., metal-Oxide-Semiconductor field effect transistors, is a Semiconductor device that operates using the field effect principle. The MOS tube is used for conducting fixed voltage cut-off, a cut-off voltage is preset, the cut-off voltage can be the voltage when the discharge is finished, the cut-off voltage can also be the safety voltage which is higher than the voltage when the discharge is finished, when the discharge voltage reaches the cut-off voltage, the fact that the residual electric quantity in the target battery is continuously output is possibly damaged, and therefore a preset leakage protection mode of the target battery is triggered, the target battery enters a deep sleep state, and the power consumption of the battery is greatly reduced.
In an alternative implementation manner of this embodiment, when the discharge voltage reaches the cut-off voltage, the step of triggering the leakage protection mode of the battery includes: determining all functional components connected with the target battery; determining a target functional component higher than a level threshold according to the importance level of the functional component; the control target battery supplies power to the target functional component.
Specifically, in the present embodiment, the functional components include all components connected to or powered by the target battery, and the importance level of the functional components is determined by: when the residual capacity of the target battery is insufficient, the functional component still needs to be powered on, for example, a main control MCU on a main board is the most important component and needs to be powered on all the time, so that if an important grade is to be set, the main control MCU is a first important grade; for example, in the above super power saving mode with less than 10% on, in the power saving mode, the brightness of the screen is greatly reduced, the mobile data is automatically turned off, and the bluetooth is turned off, wherein the display component and the wireless component are non-target functional components with low importance level. The grade threshold value can be set when the target terminal is produced, and when the leakage protection mode of the target battery is triggered, the target functional component is determined according to the importance grade of each functional component and the target battery is controlled to supply power to the target functional component. And in the earth leakage protection mode, only power is supplied to the target functional component, and other functions of the target functional component are not available (namely, the target functional component is in an activated state, and the target functional component cannot have other functions of consuming electric quantity), so that deep sleep of the battery is realized.
In an optional implementation manner of this embodiment, the target functional component includes a main control MCU, and the step of controlling the target battery to supply power to the target functional component includes: determining a protection voltage for maintaining the operation of a central processing unit of the main control MCU; and controlling the target battery to supply power to the main control MCU according to the protection voltage.
Specifically, in this embodiment, the protection voltage for maintaining the operation of the central processing unit of the MCU is determined in advance, where the protection voltage is obtained by performing power supply test on the master control MCU several times, when the target battery supplies power to the master control MCU, since the protection voltage is smaller, only the central processing unit can be supplied with power, and other basic functional units and various interfaces cannot continue to supply power, at this time, the master control MCU supplies power only with a heartbeat (crystal oscillator is simply called a quartz crystal resonator (quartzcrystal oscillator), which is called a heart of a circuit system, and provides a "heartbeat" for the whole system.
In an alternative implementation manner of this embodiment, after the step of triggering the leakage protection mode of the target battery when the discharge voltage reaches the cutoff voltage, the method further includes: detecting the current state of the target battery according to the charging detection module; and when the target battery is detected to be in a charging state, releasing the leakage protection mode.
Specifically, in the actual transportation and storage process, the equipment is started up possibly due to external pressure, electromagnetic interference and other reasons, and the product is in a starting-up state and can consume the electric quantity of the lithium battery. In this embodiment, the target functional component includes a battery charging detection module and a state indication module, where the battery charging detection module is configured to detect a charging state of the target battery, and the state indication module outputs an electrical signal to the main control MCU according to the charging state, and when the first port of the main control MCU receives the electrical signal, determines that the target battery is in the charging state, and releases the leakage protection mode of the target battery.
Based on the embodiment scheme of the application, detecting the current residual capacity of the target battery; detecting the discharge voltage of the target battery when the current residual electric quantity is lower than a preset electric quantity threshold value; when the discharge voltage reaches the cutoff voltage, the leakage protection mode of the target battery is triggered. By implementing the scheme of the application, when the electric quantity of the target battery is lower than the preset electric quantity threshold value, the discharge voltage of the target battery is detected, and when the discharge voltage reaches the cut-off voltage, the target battery is subjected to leakage protection, so that the permanent loss of the battery capacity caused by overdischarge of the target battery is prevented.
Fig. 2 is a second basic flowchart of the battery leakage protection method according to the present embodiment, where the battery leakage protection method includes the following steps:
step 110, detecting the current residual capacity of the target battery;
step 140, detecting the current running state of the target terminal corresponding to the target battery when the current residual electric quantity is higher than a preset electric quantity threshold value;
step 150, periodically detecting the discharge amount of the target battery when the target terminal is in a static state;
step 160, triggering the leakage protection mode of the target battery when the discharge amount of the target battery is greater than the preset electric quantity threshold value in the preset period.
Specifically, the current operating state includes static and dynamic states, and the static state represents a standby state of the mobile phone. In practical applications, electronic products may be standby for a long time before being sold, or battery leakage occurs when they are used at ordinary times. Therefore, in addition to entering the leakage protection mode when the electric quantity of the target battery is too low, in this embodiment, when the current residual electric quantity of the target battery is higher than the preset electric quantity threshold value, the current running state of the corresponding target terminal is detected, that is, whether the target terminal is currently in a used state is judged, and when the target terminal is being used, the target battery is in a normal discharging state, and the discharging voltage is also higher than the cut-off voltage, so that the leakage protection mode is not triggered. And when the target terminal is in a static state, the battery electric quantity is kept unchanged under the standard condition, so that the discharge quantity of the target battery is periodically detected in the static process of the target terminal, and when the discharge quantity of the target battery in a preset period is larger than a preset electric quantity threshold value, the target battery is determined to be in a discharge abnormal state, the electric leakage protection mode of the target battery is triggered, and the battery is prevented from being overdischarged in a state of being unused for a long time, so that the battery activity is influenced.
Fig. 3 is a third basic flowchart of the battery leakage protection method according to the present embodiment, where the battery leakage protection method includes the following steps:
step 110, detecting the current residual capacity of the target battery;
step 170, detecting the instruction type of an operation instruction input by a user when the current residual electric quantity is higher than a preset electric quantity threshold value;
180, when the operation instruction is a mode switching instruction, determining a preset key according to the switched corresponding mode;
step 190, detecting the pressing duration of a preset key;
step 200, when the pressing time length meets a preset time length threshold value, determining that the operation instruction is a leakage protection instruction;
step 210, entering a leakage protection mode according to the leakage protection instruction.
Besides, when the battery power of the target terminal is too low or the target terminal is standby for a long time, the situation that the target battery automatically enters the leakage protection mode and then the user manually enters the leakage protection mode according to the actual requirement is included in the embodiment.
Specifically, when the current residual electric quantity of the target battery is higher than a preset electric quantity threshold value, detecting whether an operation instruction input by a user exists in the target terminal according to the sensing device of the target terminal, and judging the instruction type of the current operation instruction when the operation instruction is detected, for example, a single finger touches a screen and slides upwards to enter a background interface, and two fingers touch the screen and slide upwards to enter a mode switching interface. If the specific operation of the corresponding key is shown in fig. 4, the factory mode is entered, a corresponding preset key instruction of the leakage protection mode is found in the factory mode, the pressing duration of the preset key is detected according to the sensing device, when the pressing duration meets the preset duration threshold, the key instruction is determined to be the leakage protection instruction, and the leakage protection mode is entered according to the leakage protection instruction.
It should be noted that the above instruction receiving manner and the instruction determining manner are only illustrative, and specific operation instructions may also be other manners, for example, a plurality of fingers simultaneously slide on the screen, a direction in which the fingers slide, a touch screen and a button are simultaneously performed may be used as operation instructions, and different operation instructions are determined by different operation manners, which is not limited in detail.
Optionally, when the device is set in factory, a key operation can be directly set, an operation instruction corresponding to the key operation is set as a leakage protection instruction, and when a user performs the leakage protection operation in the mode, the device can enter a leakage protection mode only by performing the key operation, for example, a certain preset key is pressed for a long time to directly enter the leakage protection mode.
In an optional implementation manner of this embodiment, after the step of determining that the operation instruction is the leakage protection instruction, the method further includes: outputting corresponding instruction verification information according to the leakage protection instruction; and when receiving a user confirmation instruction, controlling the target battery to enter a leakage protection mode.
Specifically, in practical application, taking a mobile phone as an example, a user usually puts the mobile phone into a pocket when not in use, and if forgetting to turn off the screen at this time, the mobile phone is easy to trigger misoperation due to friction between the mobile phone and the pocket. Therefore, in this embodiment, when the target terminal receives the leakage protection instruction input by the user, the corresponding instruction verification information is output to the user, that is, the instruction confirmation popup window is popped up on the display screen of the target terminal, or the user is prompted to perform secondary confirmation on the leakage protection instruction through the signal indicator lamp. When a confirmation instruction input by a user again is received, the leakage protection instruction is determined not to be misoperation of the user, so that the target battery is controlled to enter the leakage protection mode, and unnecessary trouble is caused by the fact that the target terminal enters the leakage protection mode due to misoperation of the user is prevented.
