In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
In order to explain the technical solution of the present application, the following description will be given by way of specific examples.
Example 1
Referring to fig. 1, a charging detection method provided in an embodiment of the present application is described below, where the charging detection method in the embodiment of the present application includes:
step 101, acquiring the charging state of a battery in the charging process of the battery;
in this embodiment, the battery may include a cell, a protection circuit, a casing, and the like, where the cell may be an electrochemical cell including a positive electrode and a negative electrode. For example, the charging state of the battery may include information of a change of a charging parameter (e.g., temperature, voltage, current, amount of electricity, etc.) when the battery is charged, a current charging phase (e.g., a constant voltage charging phase, a constant current charging phase), and the like.
Optionally, when the battery starts to be charged, the charging parameter of the battery is set.
In this embodiment of the application, when the battery starts to be charged, it may be detected that a charger is connected to a preset interface of a terminal device where the battery is located, or when the battery starts to store electric charge, and the specific definition of the battery may be set according to the battery and an application scenario.
The charging parameter may include a cut-off voltage, a saturation voltage, a charging current upper limit value, and the like of the battery cell. The charging parameter may be set in various manners, for example, by a Power Management Integrated Circuit (PMIC) in a terminal device where the battery is located, where the charging parameter may be predetermined in the PMIC (for example, predetermined by a research and development team of the battery), or may be set according to an instruction input by a user through a preset interface.
Step 102, judging whether the charging state is in an abnormal state;
in this embodiment, the abnormal state may include a state that a charging parameter, a charging stage, and the like of the battery are different from a preset state. For example, the charging phase may include a constant current charging phase and a constant voltage charging phase, when the charging phase of the battery is in the constant current charging phase, the charging current of the battery may be kept constant and at a higher value, the cell voltage of the battery may be continuously increased until reaching a cut-off voltage, and the charging phase of the battery enters the constant voltage charging phase after the cell voltage of the battery reaches the cut-off voltage; when the charging phase of the battery is in the constant voltage charging phase, the cell voltage may be maintained at the cut-off voltage, and the charging current may be gradually decreased until the charging is completed or the charging is stopped. In the constant-current charging stage, if the cell voltage does not reach the cut-off voltage, the cell enters the constant-voltage charging stage, which may cause an abnormal situation that the cell is not fully charged, so that the charging state of the battery is in an abnormal state; in the constant voltage charging stage, if the cell voltage of the battery exceeds a preset cut-off voltage when the battery is in the constant voltage charging stage, the charging voltage of the battery entering the constant voltage charging stage is too high, which may cause an overcharge abnormal condition of the battery, and thus the charging state of the battery is in an abnormal state. Therefore, it is possible to determine whether or not the charging state is in an abnormal state based on the charging parameter, the charging stage, and the like.
Step 103, if the charging state is in an abnormal state, adjusting the current charging parameter of the battery, wherein the charging parameter comprises the cut-off voltage of the battery.
In the embodiment of the present application, before charging, the terminal device usually sets the cut-off voltage of the battery during charging in advance, and therefore, when the state of charge is in an abnormal state, it may be that an actual effective value of the cut-off voltage during charging of the battery is deviated from the cut-off voltage set in advance. Therefore, the state of charge can be adjusted by adjusting a charging parameter such as the cutoff voltage, and the deviation can be adjusted.
Optionally, in this embodiment of the application, the obtaining the charging state of the battery during the charging process of the battery includes:
in the process of charging the battery, acquiring current charging stage information and cell voltage of the battery according to a preset time interval;
correspondingly, the judging whether the charging state is in an abnormal state includes:
and judging whether the charging state is in an abnormal state or not according to the current charging stage information and the cell voltage.
In this embodiment, the current charging stage information may indicate a current charging stage of the battery. The charging stages may include a constant voltage charging stage and a constant current charging stage, and for each charging stage, the change conditions of the charging voltage, the charging current and the like corresponding to the charging stage meet a certain rule, so that according to the current charging stage and the cell voltage, whether the charging state is in an abnormal state or not may be determined. Illustratively, the preset time interval may be 3 seconds, 5 seconds, or the like.
Optionally, the current charging stage information is used to indicate that the battery is currently in a constant current charging stage or a constant voltage charging stage;
correspondingly, the determining whether the charging state is in an abnormal state according to the current charging stage information and the cell voltage includes:
judging whether the battery is in a constant current charging stage at present and the cell voltage is not less than the current cut-off voltage according to the current charging stage information and the cell voltage;
if the battery is currently in a constant current charging stage and the cell voltage is not less than the current cut-off voltage, determining that the charging state is in a first abnormal state, wherein the abnormal state comprises a first abnormal state;
or,
judging whether the battery is in a constant voltage charging stage at present and the cell voltage is smaller than a current cut-off voltage according to the current charging stage information and the cell voltage;
and if the battery is currently in a constant voltage charging stage and the cell voltage is smaller than the current cut-off voltage, determining that the charging state is in a second abnormal state, wherein the second abnormal state is included in the abnormal state.
Optionally, if the battery is currently in a constant current charging stage and the cell voltage is not less than a current cut-off voltage, determining that the charging state is in a first abnormal state; or, if the battery is currently in a constant voltage charging stage and the cell voltage is smaller than a current cut-off voltage, determining that the charging state is in a second abnormal state includes:
if the battery is detected to be in a constant current charging stage for N times continuously and the cell voltage is not less than the current cut-off voltage, determining that the charging state is in a first abnormal state; or if it is detected that the battery is currently in a constant-voltage charging stage and the cell voltage is lower than the current cut-off voltage for M consecutive times, determining that the charging state is in a second abnormal state, wherein N, M are integers greater than 1.
Optionally, if the charging state is in an abnormal state, adjusting the current charging parameter of the battery includes:
if the charging state is in a first abnormal state, reducing the current cut-off voltage by a first preset value;
and if the charging state is in a second abnormal state, increasing the current cut-off voltage by a second preset value.
In the embodiment of the present application, the current cutoff voltage may be preset, for example, may be set before charging, or may be set prior to the current time during charging. The first abnormal state is distinguished from the second abnormal state. When the charging state is in a first abnormal state, it can be considered that the actually effective cut-off voltage is greater than the current cut-off voltage in the charging process of the battery, so that the current cut-off voltage is reduced by a first preset value; when the charging state is in the second abnormal state, it may be considered that the cut-off voltage actually effective in the charging process of the battery is smaller than the current cut-off voltage, and therefore, the current cut-off voltage is increased by a second preset value. And whether the corresponding charging state is detected for N times or M times continuously can be judged, so that the interference caused by transient state floating in the charging process of the battery can be avoided, and the stability and the accuracy of the detection of the charging state are higher.
In the embodiment of the application, according to the current charging stage information and the cell voltage, whether the current cut-off voltage of the battery is deviated from the actually effective cut-off voltage or not can be judged, and adjustment is performed, so that abnormal conditions such as insufficient charging or overcharging of the battery are effectively reduced, and the charging stability is improved.
As can be seen from the above, in the embodiment of the present application, by obtaining the charge state of the battery and determining whether the charge state is in an abnormal state, the charge parameters such as the cut-off voltage of the battery can be adjusted in time when the battery is in the abnormal state, so that the adjustment can still be performed according to the charge state when the battery manufacturer or the user determines the parameters such as the cut-off voltage in advance, thereby avoiding a situation that a manufacturer or a terminal device manufacturer of the battery chooses to reduce the parameters such as the cut-off voltage in advance to improve the safety of the battery in order to avoid potential safety hazards caused by errors of the parameters such as the cut-off voltage in the use process of the battery. Therefore, through this application embodiment, can promote battery charging's stability and security, can reduce the battery through adjusting cutoff voltage and appear filling not full condition simultaneously to promote the charge efficiency of battery, have stronger practicality and ease for use.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
Example 2
On the basis of the foregoing embodiment 1, another charging detection method provided in the embodiment of the present application is described below, with reference to fig. 2, where the charging detection method in the embodiment of the present application includes:
step 201, in the process of charging a battery, acquiring the charging state of the battery;
step 202, judging whether the charging state is in an abnormal state;
step 203, if the charging state is in an abnormal state, adjusting the current charging parameters of the battery, wherein the charging parameters comprise the cut-off voltage of the battery;
in the embodiment of the present application, the steps 201, 202, and 203 are the same as or similar to the steps 101, 102, and 103, and reference may be specifically made to the related descriptions of the steps 101, 102, and 103, which are not repeated herein.
And step 204, returning to the step of acquiring the charging state of the battery and the subsequent steps until the battery is charged.
In this embodiment of the present application, the step of obtaining the charging state of the battery and the subsequent steps may be executed again at a preset time interval after the current charging parameter of the battery is adjusted. It should be noted that the completion of the battery charging may refer to that the battery charging reaches a preset electric quantity, such as 100% electric quantity, or that the charging is finished, such as the charger is disconnected from the terminal device where the battery is located.
Optionally, after the charging of the battery is completed, the method further includes:
and acquiring the charging parameters when the battery is charged, comparing the charging parameters when the battery is charged with the charging parameters set when the battery starts to be charged, and sending the comparison result to a designated terminal.
In this embodiment of the application, the comparison result may be sent to the designated terminal through a designated communication mode (such as a wireless communication mode or a wired communication mode) by the terminal device where the battery is located, or may be transmitted to the designated terminal through a preset interface, where a specific sending mode is not limited herein. The designated terminal may be a terminal device such as a server designated by a manufacturer of the battery or a producer of a terminal device in which the battery is located. By sending the comparison result to the designated terminal, a manufacturer of the battery or a manufacturer of the terminal device where the battery is located can obtain the deviation between the actually effective charging parameter and the preset charging parameter in the charging process in time, so that the battery can be analyzed and adjusted in time.
For example, the comparison result may include a difference between the charging parameter when the charging of the battery is completed and the charging parameter set when the charging of the battery is started, for example, a difference between the charging parameter when the charging current, the cut-off voltage, the temperature, and the like, are adjusted or changed during the charging process, and the charging of the battery is started.
Optionally, after the charging of the battery is completed, the method further includes:
and when the battery is detected to start charging again, setting the charging parameters of the current charging according to the charging parameters of the battery when the previous charging is finished.
In the embodiment of the present application, the charging parameter of the current charging may be set by obtaining a comparison result between the charging parameter when the previous charging is completed and the charging parameter set when the previous charging is started, where the charging parameter may include the cut-off voltage. In addition, since the deviation of the charging parameter may be influenced by factors such as the temperature during charging, the charging parameter may further include an ambient temperature value, a cell temperature value, and the like. For example, if it is detected that the difference between the ambient temperature value during the previous charging and the ambient temperature value during the current charging is large, the cutoff voltage for the current charging may be set according to a cutoff voltage preset by a user or a manufacturer; if the difference between the ambient temperature value during the previous charging and the ambient temperature value during the current charging is detected to be small, the cut-off voltage during the current charging can be set according to the cut-off voltage during the previous charging.
As can be seen from the above, according to the embodiment of the present application, the step of obtaining the charging state of the battery and the subsequent steps can be continuously executed in the charging process, for example, the step of obtaining the charging state of the battery and the subsequent steps are executed once every preset time interval, the charging state of the battery can be continuously monitored, the abnormal state can be correspondingly adjusted, the stability and the safety of battery charging can be improved, and the present application has strong practicability and usability.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
