Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
The technical scheme provided by the embodiment of the disclosure relates to a terminal, which can be a mobile phone, a tablet computer, a game console, medical equipment, a notebook computer and other equipment provided with a soft package lithium battery, and the embodiment of the disclosure is not limited thereto. In the related art, the lithium battery to be detected is placed in a negative pressure environment, if the lithium battery to be detected is scratched or pricked, part of electrolyte of the lithium battery to be detected can volatilize in the atmosphere in the negative pressure environment, so that the content of volatile gas in the atmosphere can be detected through the detection probe, and whether the lithium battery to be detected is damaged or not is determined. However, the detection method needs to specially place the lithium battery to be detected in a negative pressure environment for detection, and the real-time performance of detection is poor. In the technical scheme provided by the embodiment of the disclosure, the terminal acquires the first side voltage value of the battery at the first moment and the second side voltage value of the battery at the second moment in real time, and determines whether the battery is damaged or not according to the judgment of the first side voltage value and/or the second side voltage value, so that the real-time detection of the battery damage is realized.
Fig. 1a is a flowchart illustrating a battery breakage detection method applied to a terminal according to an exemplary embodiment, and as shown in fig. 1a, the battery breakage detection method includes the following steps 101 to 102:
in step 101, a first side voltage value of the battery at a first time and a second side voltage value of the battery at a second time are obtained.
And the battery is a soft package lithium battery before the first moment and the second moment.
The example, in order to obtain the edge voltage value of the battery, a hardware circuit needs to be added, the hardware circuit can be two conducting strips and a conducting wire, one conducting strip is connected with the positive electrode tab of the battery, the other conducting strip is connected with the soft package aluminum plastic film of the battery, the two conducting strips are connected to corresponding pins of the battery protection board respectively through a conducting wire, or the two conducting strips are directly connected to corresponding pins of a processor at a terminal respectively through conducting wires, two conducting strip users collect the voltage between the positive electrode tab of the battery and the soft package aluminum plastic film, namely the edge voltage of the battery, the protecting board or the processor obtains the edge voltage collected by the conducting strips according to a preset frequency, so that the first edge voltage value at a first moment and the second edge voltage value at a second moment can be obtained.
It should be noted that, in the terminal, the battery protection board is connected to the processor, so that when the battery protection board collects a first side voltage value of the battery at a first time and a second side voltage value of the battery at a second time, the first side voltage value at the first time and the second side voltage value at the second time are sent to the processor, so that the processor obtains the first side voltage value at the first time and the second side voltage value at the second time.
In step 102, it is determined that the battery is broken when the first side voltage value and/or the second side voltage value satisfy a set condition.
Wherein, the first side voltage value and/or the second side voltage value satisfy a set condition, including one or a combination of the following:
the first side voltage value is greater than or equal to a first preset value;
the difference between the second edge voltage value and a first preset voltage value is greater than or equal to a second preset value, wherein the first preset voltage value is the edge voltage value at a third moment when the battery is not damaged, the difference between the second moment and the first moment is equal to the difference between the third moment and an initial test moment, and the third moment is before the first moment;
the voltage slope from the change of the first edge voltage value to the second edge voltage value is greater than a preset slope, the preset slope is the voltage slope from the change of the first preset voltage value to the second preset voltage value, and the second preset voltage value is the edge voltage value at the initial test moment when the battery is not damaged.
The method specifically comprises the following steps:
in the first method, the first side voltage value is compared with a first preset value, and when the first side voltage value is determined to be greater than or equal to the first preset value, the battery is determined to be damaged.
Illustratively, when the terminal acquires a first side voltage value of the battery at a first time, the first side voltage value is compared with a first preset value stored in advance, and when the first side voltage value is determined to be greater than or equal to the first preset value, the side voltage value of the battery at the first time is abnormal, so that the battery is determined to be damaged; when the first side voltage value is determined to be smaller than the first preset value, the side voltage value of the battery at the first moment is normal, and therefore the battery is determined not to be damaged.
It should be noted that, the specific value of the first preset value is not limited in the embodiment of the present disclosure, and may be set according to actual requirements, for example, the first preset value is 500mV (millivolts).
And comparing the difference value between the second side voltage value and the first preset voltage value with a second preset value, and determining that the battery is damaged when the difference value between the second side voltage value and the first preset voltage value is greater than or equal to the second preset value.
Illustratively, when a terminal acquires a second side voltage value of the battery at a second moment, comparing the second side voltage value with a first preset voltage value difference value and a second preset value at a third moment when the battery is not damaged, and when the difference value between the second side voltage value and the first preset voltage value is determined to be greater than or equal to the second preset value, indicating that the side voltage value of the battery at the second moment is abnormal, so as to determine that the battery is damaged; and when the difference value between the second side voltage value and the first preset voltage value is smaller than the second preset value, the side voltage value of the battery at the second moment is normal, so that the battery is determined not to be damaged.
The first preset voltage value is a side voltage value of the battery collected at the third moment under the condition that the battery is ensured not to be damaged, and the side voltage value is stored in the terminal in advance; the difference value between the second moment and the first moment is limited to be equal to the difference value between the third moment and the initial test moment, so that the first side voltage value corresponding to the first moment when the battery is damaged is compared with the side voltage value corresponding to the initial detection when the battery is not damaged, and the second side voltage value acquired when the battery passes through the difference value between the second moment and the first moment after being damaged is compared with the first preset voltage value acquired when the battery passes through the third moment when the battery is not damaged, so that the detection moment when the battery is damaged is identical to the detection moment when the battery is not damaged, and whether the battery is damaged can be accurately detected.
It should be noted that, the specific value of the second preset value is not limited in the embodiment of the present disclosure, and may be set according to actual requirements, for example, the second preset value is 200 mV.
And a third method, which is to obtain a voltage slope from the change of the first side voltage value to the second side voltage value, compare the voltage slope from the change of the first side voltage value to the second side voltage value with a preset slope, and determine that the battery is damaged when the voltage slope is greater than the preset slope.
Illustratively, when a terminal acquires a first side voltage value at a first moment and a second side voltage value at a second moment, subtracting the second side voltage value from the first side voltage value to obtain a side voltage difference value, subtracting the first moment from the second moment to obtain a time difference value, and dividing the side voltage difference value by the time difference value to obtain a voltage slope; at this time, the voltage slope is compared with a preset slope, and the voltage slope represents the state when the battery is damaged and the preset slope represents the state when the battery is not damaged, so that when the voltage slope is larger than the preset slope, the current state of the battery is different from the state when the battery is not damaged, and the battery is determined to be damaged; when the voltage slope is equal to the preset slope, the current state of the battery is the same as the state of the battery when the battery is not damaged, and therefore the battery is determined not to be damaged.
And comparing the first side voltage value with a first preset value, comparing the difference value between the second side voltage value and a first preset voltage value with a second preset value when the first side voltage value is determined to be greater than or equal to the first preset value, and determining that the battery is damaged when the difference value between the second side voltage value and the first preset voltage value is determined to be greater than or equal to the second preset value.
For example, when it is determined that the first side voltage value is greater than or equal to the first preset value, and the difference between the second side voltage value and the first preset voltage value is greater than or equal to the second preset value, it is indicated that both the first side voltage value at the first time and the second side voltage value at the second time of the battery are abnormal, so that the battery can be further determined to be damaged, and the accuracy of detecting the battery damage is improved.
And comparing the first side voltage value with a first preset value, acquiring a voltage slope of the first side voltage value changing to the second side voltage value when the first side voltage value is determined to be greater than or equal to the first preset value, comparing the voltage slope of the first side voltage value changing to the second side voltage value with a preset slope, and determining that the battery is damaged when the voltage slope is determined to be greater than the preset slope.
And comparing the difference between the second edge voltage value and the first preset voltage value with a second preset value, obtaining the voltage slope of the first edge voltage value changing to the second edge voltage value when the difference between the second edge voltage value and the first preset voltage value is determined to be greater than or equal to the second preset value, comparing the voltage slope of the first edge voltage value changing to the second edge voltage value with a preset slope, and determining that the battery is damaged when the voltage slope is determined to be greater than the preset slope.
A seventh method, comparing the first side voltage value with a first preset value, comparing a difference between the second side voltage value and a first preset voltage value with a second preset value when the first side voltage value is determined to be greater than or equal to the first preset value, obtaining a voltage slope from the first side voltage value to the second side voltage value when the difference between the second side voltage value and the first preset voltage value is determined to be greater than or equal to the second preset value, comparing the voltage slope from the first side voltage value to the second side voltage value with a preset slope, and determining that the battery is damaged when the voltage slope is determined to be greater than the preset slope.
For example, when the terminal determines that three conditions that the first side voltage value is greater than or equal to the first preset value, the difference between the second side voltage value and the first preset voltage value is greater than or equal to the second preset value, and the voltage slope is greater than the preset slope are simultaneously met, it indicates that the battery is damaged, and the accuracy of detecting the damage of the battery is improved.
As shown in fig. 1b, which is a graph of the side voltage values of the battery before and after the breakage of the battery at different times, as can be seen from fig. 1b, the side voltage corresponding to the time t0 (the initial test time in the above description) is the second preset voltage value (the voltage value corresponding to the initial test time when the battery is not damaged), the side voltage corresponding to the time t1 (the third time in the above description) is the first preset voltage value (the voltage value corresponding to the third time when the battery is not damaged), the side voltage corresponding to the time t2 (the first time in the above description) is the first side voltage value (the voltage value corresponding to the first time when the battery is damaged), and the side voltage corresponding to the time t3 (the second time in the above description) is the second side voltage value (the voltage value corresponding to the second time when the battery is damaged).
Further, when the first side voltage value and the second side voltage value satisfy a set condition, that is, a condition in any one of the seven methods described above, the method further includes:
and acquiring a first voltage value of the battery at a fourth moment and a second voltage value of the battery at a fifth moment, determining that the difference value between the third preset voltage value and the first voltage value is greater than or equal to the third preset value, and determining that the battery is damaged when the difference value between the third preset voltage value and the second voltage value is greater than or equal to the fourth preset value.
And the third preset voltage value is the voltage value of the battery when the battery is not damaged.
For example, in the terminal, the positive electrode tab and the negative electrode tab of the battery are respectively connected with the protection plate of the terminal or the processor of the terminal, so that the terminal can acquire the voltage value between the positive electrode tab and the negative electrode tab of the battery, and the terminal can respectively acquire the voltage value of the battery at the fourth moment, namely the first voltage value, and the voltage value at the fifth moment, namely the second voltage value, according to the preset time. When the terminal acquires the first voltage value and the second voltage value, in order to determine whether the battery is seriously damaged at the moment, the difference value between the third preset voltage value of the battery when the battery is not damaged and the acquired first voltage value needs to be compared with a third preset value, when the difference value between the third preset voltage value and the first voltage value is determined to be greater than or equal to the third preset value, the voltage value of the battery is seriously reduced at the moment, further, the difference value between the third preset voltage value and the second voltage value is compared with a fourth preset value, when the difference value between the third preset voltage value and the second voltage value is determined to be larger than or equal to the fourth preset value, the voltage of the battery is increased, but not to the third preset voltage value, that is, not to the voltage value at which the breakage of the battery does not occur, therefore, the serious damage of the battery can be determined by that the voltage of the battery firstly drops and then rises to be lower than the third preset voltage value.
In addition, when the terminal determines that the difference value between the third preset voltage value and the first voltage value is smaller than the third preset value, it indicates that the voltage of the battery is not greatly changed compared with the voltage when the battery is not damaged, and it can be determined that the battery is not seriously damaged, and only the soft package aluminum plastic film is damaged, but the internal structure of the battery is not damaged.
It should be noted that specific values of the third preset value and the fourth preset value are not limited in the embodiment of the present disclosure, and may be set according to actual requirements, for example, the third preset value is 300mV, and the fourth preset value is 100 mV.
Taking the seventh method as an example, when the condition in the seventh method is satisfied, the method further includes:
when the voltage slope is determined to be larger than the preset slope, acquiring a first voltage value of the battery at a fourth moment and a second voltage value of the battery at a fifth moment; comparing the difference between a third preset voltage value and the first voltage value with a third preset value; when the difference value between the third preset voltage value and the first voltage value is determined to be greater than or equal to the third preset value, determining whether the difference value between the third preset voltage value and the second voltage value is greater than or equal to a fourth preset value; and when the difference value between the third preset voltage value and the second voltage value is greater than or equal to the fourth preset value, determining that the battery is damaged.
Further, when the first side voltage value and the second side voltage value satisfy a set condition, that is, a condition in any one of the seven methods described above, the method further includes:
and acquiring the temperature of the battery, wherein the first side voltage value and the second side voltage value meet set conditions, and when the difference value between the temperature of the battery and the preset temperature is greater than or equal to a fifth preset value, determining that the battery is damaged.
The preset temperature is a temperature value of the battery when the battery is not damaged.
For example, in the terminal, in order to ensure reliable operation of the battery, a temperature sensor for detecting the temperature of the battery is generally provided, and the temperature sensor is connected to a battery protection board or a processor of the terminal, so that the terminal can acquire the temperature of the battery in real time, compare the temperature of the battery with a temperature value of the battery when the battery is not damaged, and when the acquired temperature of the battery is determined to be greater than or equal to a fifth preset value, it indicates that the temperature of the battery is increased, and the damage of the internal structure of the battery can cause the temperature of the battery to be increased, so that it can be determined that the battery is seriously damaged, that is, the internal structure of the battery is damaged, through the temperature increase of the battery.
It should be noted that, the specific value of the fifth preset value is not limited in the embodiment of the present disclosure, and may be set according to actual requirements, for example, the fifth preset value is 5 ℃.
Taking the seventh method as an example, when the condition in the seventh method is satisfied, the method further includes:
when the voltage slope is determined to be larger than the preset slope, acquiring the temperature of the battery; comparing the difference between the temperature of the battery and a preset temperature with a fifth preset value; and when the difference value between the temperature of the battery and the preset temperature is larger than or equal to the fifth preset value, determining that the battery is damaged.
For example, the temperature of the battery may be acquired when it is determined that the difference between the third preset voltage value and the second preset voltage value is greater than or equal to the fourth preset value; comparing the difference between the temperature of the battery and a preset temperature with a fifth preset value; the preset temperature is a temperature value of the battery when the battery is not damaged; and when the difference value between the temperature of the battery and the preset temperature is larger than or equal to the fifth preset value, determining that the battery is damaged.
As shown in fig. 1c, which is a graph of the voltage and temperature of the battery before and after the breakage of the battery, it can be seen that the voltage of the battery after the breakage of the battery is first decreased and then increased to a certain value, and the certain value is smaller than the voltage of the battery before the breakage; after the battery is broken, the temperature of the battery is slowly raised to a certain value.
Further, as shown in fig. 1d, after the step 102 is executed, the method further includes a step 103:
in step 103, when it is determined that the battery is broken, an alarm signal is displayed.
Optionally, in the case that it is determined that the battery is broken according to one of the seven methods, a first level alarm signal is displayed.
For example, when the terminal determines that the battery is damaged according to one of the seven methods, it indicates that at least the soft package aluminum plastic film of the battery is damaged, and belongs to a case of slight damage of the battery, and at this time, a first-level alarm signal may be displayed, for example, a message for indicating that the soft package aluminum plastic film of the battery is damaged is broadcasted by voice; or displaying a message for indicating that the battery soft package aluminum plastic film is damaged on a display screen of the terminal.
Optionally, when the condition in one of the seven methods is satisfied and the difference between the third preset voltage value and the second voltage value is determined to be greater than or equal to the fourth preset value, it is determined that the battery is damaged; or, when the condition in one of the seven methods is satisfied and the difference between the temperature of the battery and the preset temperature is determined to be greater than or equal to a fifth preset value, determining that the battery is damaged; or, when the condition in one of the seven methods is satisfied, and when it is determined that the difference between the third preset voltage value and the second voltage value is greater than or equal to the fourth preset value, or when it is determined that the difference between the temperature of the battery and the preset temperature is greater than or equal to the fifth preset value, and it is determined that the battery is damaged, displaying a second-level alarm signal.
Wherein the degree of battery breakage indicated by the second level alarm signal is greater than the degree of battery breakage indicated by the first level alarm signal.
For example, when the terminal determines that the first side voltage value is greater than or equal to the first preset value, the difference between the second side voltage value and the first preset voltage value is greater than or equal to the second preset value, and the voltage slope is greater than the preset slope, in order to further determine whether the internal structure of the battery, such as the electrolyte, etc., is leaked, the first voltage value and the second voltage value of the battery are acquired, when the difference value between the third preset voltage value and the first voltage value is determined to be greater than or equal to the third preset value and the difference value between the third preset voltage value and the second voltage value is determined to be greater than or equal to the fourth preset value, the situation that the voltage of the battery is firstly reduced and then increased is shown, therefore, the situation that the internal structure of the battery is damaged and the battery is seriously damaged can be determined, the second-level alarm signal can be displayed at the moment, for example, the voice broadcast is used for indicating that the aluminum plastic film and the internal structure of the battery soft package are damaged; or displaying a message for indicating that the soft package aluminum-plastic film and the internal structure of the battery are damaged on a display screen of the terminal; or the second-level alarm signal is a signal for cutting off the battery to supply power to each electrical appliance of the terminal, so that the terminal stops working when receiving the signal, and the fault of the whole terminal caused by the damage of the battery is avoided.
The embodiment of the disclosure provides a battery breakage detection method, a terminal acquires a first side voltage value of a battery at a first moment and a second side voltage value of the battery at a second moment in real time, determines whether the battery is broken according to the judgment of the first side voltage value and/or the second side voltage value, and displays an alarm signal when the battery is determined to be broken, so that the real-time detection of the battery breakage is realized; and whether the battery is damaged or not is further judged by combining the first voltage value and the second voltage value of the battery and the temperature of the battery, so that the accuracy of detecting the damage of the battery is improved.
