Based on the above mobile terminal hardware structure and communication network system, the present invention provides various embodiments of the method.
Referring to fig. 3, fig. 3 is a schematic flow chart of a battery state detection method according to a first embodiment of the present invention.
In this embodiment, the method for detecting the battery state includes the following steps:
step S10, when a detection instruction of the battery state is detected, acquiring the current mode of the battery, and when the current mode is a charging mode, acquiring the current voltage of the battery;
along with the rapid development of the electronic industry, the intelligent degree of the mobile terminal is higher and higher. In addition to paying more attention to intelligent and humanized design, mobile terminal research and development companies integrate more and more functions on mobile terminals. As the integrated performance of the mobile terminal increases, the power consumption of the terminal also increases. In addition, the contradiction between the miniaturization requirement of the terminal and the increase of the power consumption of the terminal further increases the increase of the heat productivity of the terminal. Particularly, in the charging process of the terminal battery, the charging current is easy to be overlarge, so that the temperature of the terminal equipment is rapidly increased. However, the temperature of the terminal exceeds the preset temperature, the heating time of the terminal is long, or the heating value of the terminal is large, which easily causes the internal temperature of the terminal to be too high, and since the user cannot identify whether the heating of the terminal is normal heating or abnormal heating, the heating abnormality of the terminal is easily caused, and the abnormal heating of the terminal not only reduces the user experience, but also easily causes serious and serious faults such as battery explosion. In this embodiment, the charging current of the battery in the charging mode is monitored in real time, and the specific charging current threshold is determined by combining the current voltage of the battery, so as to accurately judge whether the charging current of the battery is abnormal, thereby being capable of finding out the abnormal heating state of the terminal in time, and taking corresponding measures according to the abnormal heating state of the terminal to prevent the abnormal heating state of the terminal caused by the abnormal charging current. Specifically, the battery state detection device obtains the current mode of the terminal battery, such as a charging mode, a shutdown mode, a startup mode, a call mode, and the like, when receiving a detection instruction of the terminal battery state. Each mode corresponds to different charging standards, and after the mode of the battery is determined, whether the current charging parameters of the battery meet the requirements or not is judged according to the charging parameter threshold value corresponding to the mode. And when the current mode of the battery is determined to be the charging mode, acquiring the current voltage of the battery, namely the current electric quantity. The detection instruction can be a detection instruction triggered by a user through a button for detecting the battery state on a terminal display interface, or can be a detection instruction automatically triggered when the battery voltage of the terminal rises.
Step S20, judging whether the current charging current of the battery is higher than a preset threshold value according to the current voltage and a preset rule;
specifically, the acquired present charging current is compared with a charging current threshold according to pre-stored voltage value data and the corresponding charging current threshold. In the charging process of the battery, the charging current mode of the battery changes along with the increase of the charging capacity. The preset rule is that a charging current mode of the battery, such as a trickle charging mode, a constant current charging mode, a constant voltage charging mode and the like, is determined according to the current voltage, a corresponding charging current threshold value is determined according to the charging current mode, and then the current charging current is compared with the charging current threshold value for judgment. In addition, the charging current thresholds corresponding to the charging current modes are different from each other. The charging current threshold corresponding to the trickle charging mode is smaller than the charging current threshold corresponding to the constant-current charging mode, and the charging current threshold corresponding to the constant-current charging mode is smaller than the charging current threshold corresponding to the constant-voltage charging mode. Wherein the charging current threshold value indicates that the battery is charged at a current below the current threshold value, and the charging speed of the battery is not too high, so that abnormal heating is not caused.
And step S30, if the current value is higher than the preset threshold, determining that the state of the battery is abnormal.
Specifically, when the current charging current of the battery is higher than the preset threshold, that is, the current charging current of the battery is too large, the battery is easily damaged or exploded. If the battery is determined to be abnormal, relevant measures need to be taken according to the abnormal state of the battery, and therefore the situation that some original devices with low requirements on the environment temperature cannot work normally due to overhigh temperature of the internal environment of the terminal or the battery in the terminal is exploded due to overhigh temperature is prevented. The relevant measure may be to stop charging the battery of the terminal or to change the charging plug with a lower charging current. The mobile terminal supplier can carry out the delivery test of the relevant mobile terminal according to the invention, thereby preventing the battery of the mobile terminal from being heated and abnormal easily after delivery due to the battery parameter, and reducing the user experience or causing the occurrence of malignant faults.
The embodiment provides a method and a device for detecting a battery state and a computer storage medium, wherein the method for detecting the battery state comprises the steps of obtaining a current mode of a battery when a detection instruction of the battery state is detected, and obtaining a current voltage of the battery when the current mode is a charging mode; judging whether the current charging current of the battery is higher than a preset threshold value or not according to the current voltage and a preset rule; and if the voltage is higher than the preset threshold value, determining that the state of the battery is abnormal. Through the manner, the charging current of the battery in the charging mode is monitored in real time, and the specific charging current threshold is determined by combining the current voltage of the battery, so that whether the charging current of the battery is abnormal or not is accurately judged, and the abnormal heating state of the terminal caused by the abnormal charging current is prevented. Therefore, the invention not only prolongs the service life of the battery, but also can ensure the use safety of the battery, avoid serious faults such as battery explosion and the like, and solve the technical problem that the abnormal terminal heating caused by the charging of the terminal battery cannot be detected in time.
Referring to fig. 4, fig. 4 is a flowchart illustrating a method for detecting a battery status according to a second embodiment of the present invention.
In this embodiment, based on the embodiment described in fig. 3, the method for detecting a battery state in the present invention specifically includes, in step S20:
step S21, determining a charging current threshold of the battery according to the current voltage as a preset threshold;
in this embodiment, the current charging current mode of the battery is further determined according to the voltage value. Specifically, the present voltage is compared to various ranges of voltage thresholds. The voltage value corresponds to the electric quantity value of the battery. The voltage threshold comprises a first preset voltage threshold, a second preset voltage threshold and a third preset voltage threshold. The first preset voltage threshold is smaller than the second preset voltage threshold, and the second preset voltage threshold is smaller than the third preset voltage threshold. The third preset voltage threshold is a voltage value at which the battery is close to saturation. And determining a charging current mode, such as a trickle charging mode, a constant-current charging mode, a constant-voltage charging mode and the like, in which the current voltage is located according to the first preset voltage threshold, the second preset voltage threshold or the third preset voltage threshold, and determining a charging current threshold, namely a preset threshold, according to the charging current mode. Such as a trickle charge threshold corresponding to the trickle charge mode, a constant current charge threshold corresponding to the constant current charge mode, a constant voltage charge threshold corresponding to the constant voltage charge mode, etc.
Step S22, obtaining a current charging current of the battery, and determining whether the current charging current is higher than the preset threshold.
Specifically, the current charging current of the battery is obtained, and the current charging current is compared with the preset threshold value for judgment. Namely, the current charging current is compared and judged with a trickle charging threshold value, a constant current charging threshold value or a constant voltage charging threshold value. And when the current charging current exceeds the trickle charging threshold, the constant current charging threshold or the constant voltage charging threshold, judging that the current charging current is too large, and generating a corresponding reminding message or taking other related measures.
The embodiment provides a method and a device for detecting a battery state and a computer storage medium, wherein the method for detecting the battery state comprises the steps of obtaining a current mode of a battery when a detection instruction of the battery state is detected, and obtaining a current voltage of the battery when the current mode is a charging mode; judging whether the current charging current of the battery is higher than a preset threshold value or not according to the current voltage and a preset rule; and if the voltage is higher than the preset threshold value, determining that the state of the battery is abnormal. Through the manner, the charging current of the battery in the charging mode is monitored in real time, and the specific charging current threshold is determined by combining the current voltage of the battery, so that whether the charging current of the battery is abnormal or not is accurately judged, and the abnormal heating state of the terminal caused by the abnormal charging current is prevented. Therefore, the invention not only prolongs the service life of the battery, but also can ensure the use safety of the battery, avoid serious faults such as battery explosion and the like, and solve the technical problem that the abnormal terminal heating caused by the charging of the terminal battery cannot be detected in time.
Referring to fig. 5, fig. 5 is a flowchart illustrating a method for detecting a battery status according to a second embodiment of the present invention.
In this embodiment, based on the embodiment described in fig. 3, the method for detecting a battery state in the present invention specifically includes, in step S21:
step S211, judging whether the current voltage is lower than a first preset voltage value;
specifically, the current voltage is compared with the first preset voltage value for judgment, and the current electric quantity of the battery is determined. The first preset voltage value is the lowest voltage value of the battery which is not overdischarged, and the battery is in an overdischarge state when the first preset voltage value is lower than the first preset voltage value. The battery charging mode in the over-discharge state should correspondingly adopt the trickle charging mode to prevent the over-discharge battery from being damaged due to the excessive current.
Step S212, when the current voltage is lower than a first preset voltage value, determining that the battery is in a trickle charge mode;
specifically, when the current voltage is determined to be lower than the first preset voltage value, the battery is determined to be an overdischarge battery, and the battery is determined to adopt a trickle charge mode. The trickle charge mode is to charge the battery by a small current value and then increase the charge current when the electric quantity or voltage of the battery exceeds a certain value.
Step S213, determining a trickle charge threshold of the battery according to the trickle charge mode as a preset threshold.
Specifically, according to pre-stored data, the trickle charge mode is acquired to determine a corresponding trickle charge threshold value, namely a preset threshold value. The trickle charge threshold is a very small current value, such as 300mA, which is a current value of 300mA per hour to charge the battery in an overdischarged state.
The embodiment provides a method and a device for detecting a battery state and a computer storage medium, wherein the method for detecting the battery state comprises the steps of obtaining a current mode of a battery when a detection instruction of the battery state is detected, and obtaining a current voltage of the battery when the current mode is a charging mode; judging whether the current charging current of the battery is higher than a preset threshold value or not according to the current voltage and a preset rule; and if the voltage is higher than the preset threshold value, determining that the state of the battery is abnormal. Through the manner, the charging current of the battery in the charging mode is monitored in real time, and the specific charging current threshold is determined by combining the current voltage of the battery, so that whether the charging current of the battery is abnormal or not is accurately judged, and the abnormal heating state of the terminal caused by the abnormal charging current is prevented. Therefore, the invention not only prolongs the service life of the battery, but also can ensure the use safety of the battery, avoid serious faults such as battery explosion and the like, and solve the technical problem that the abnormal terminal heating caused by the charging of the terminal battery cannot be detected in time.
Further, the method for detecting the battery state of the present invention further includes:
step S214, when the current voltage is higher than or equal to the first preset voltage value, judging whether the current voltage is lower than or equal to a second preset voltage value;
specifically, when it is determined that the current voltage is higher than or equal to the first preset voltage value, that is, the battery is a battery with normal electric quantity, the electric quantity or voltage of the battery is further specifically determined. Firstly, the current voltage of the battery is compared with the second preset voltage value, and whether the current voltage of the battery is lower than or equal to the second preset voltage value is judged. Wherein the second preset voltage value indicates that the battery is not over-discharged but contains less power. The second preset voltage value corresponds to a constant current charging mode, i.e., the charging can be performed with the maximum allowable charging current.
Step S215, when the current voltage is lower than or equal to a second preset voltage value, determining that the battery is in a constant current charging mode;
specifically, when it is determined that the current voltage is lower than or equal to the second preset voltage value, it is determined that the battery is in a constant current charging mode. And the constant current charging threshold corresponding to the constant current charging mode is the maximum charging threshold. The constant current charging threshold is greater than the trickle charging threshold, and the constant current charging threshold is greater than the constant voltage charging threshold.
And step S56, determining the constant current charging threshold value of the battery according to the constant current charging mode, and using the constant current charging threshold value as a preset threshold value.
Specifically, according to pre-stored data, the constant current charging mode is acquired, and a corresponding constant current charging threshold, that is, a preset threshold, is determined. The constant current charging threshold is the maximum current value, such as 400mA, that is, the battery in the state of less electric quantity is charged with a current value of 400mA per hour.
Further, the method for detecting the battery state of the present invention further includes:
step S216, when the current voltage is higher than the second preset voltage value, judging whether the current voltage is lower than or equal to a third preset voltage value;
specifically, when it is determined that the current voltage is higher than or equal to the second preset voltage value, that is, the battery is a battery with a large amount of electricity, the electricity amount or the voltage of the battery is further specifically determined. Firstly, the current voltage of the battery is compared with the third preset voltage value, and whether the current voltage of the battery is lower than or equal to the third preset voltage value is judged. And the third preset voltage value indicates that the battery has more electric quantity, and the charging current needs to be reduced so as to transition to charging the battery with the electric quantity close to the saturation state. The third predetermined voltage value corresponds to a constant voltage charging mode, i.e., charging can be performed with a small charging current.
Step S217, when the current voltage is lower than or equal to a third preset voltage value, determining that the battery is in a constant voltage charging mode;
specifically, when it is determined that the current voltage is lower than or equal to the third preset voltage value, it is determined that the battery is in the constant voltage charging mode. And the constant voltage charging threshold corresponding to the constant voltage charging mode is a larger charging threshold. The constant voltage charging threshold is greater than the trickle charging threshold and less than the constant voltage charging threshold.
Step S218, determining a constant voltage charging threshold of the battery according to the constant voltage charging mode, as a preset threshold.
Specifically, according to pre-stored data, the constant voltage charging mode is acquired to determine a corresponding constant voltage charging threshold, i.e. a preset threshold. The constant voltage charging threshold is a larger current value, for example, 350mA, that is, a battery in a low-power state is charged at a current value of 350mA per hour.
Further, the method for detecting the battery state of the present invention further includes:
step S219, when the current voltage is higher than the third preset voltage value, determining that the battery is in a trickle charge mode;
specifically, when it is determined that the current voltage is higher than or equal to the third preset voltage value, it indicates that the battery contains a charge close to a saturation state. Exceeding said third preset voltage value corresponds to a trickle charge mode, i.e. continuing the charging with the minimum charging current. The trickle charge mode is applied to the state that the battery is over-discharged or is about to be charged or is already charged, so that the electric quantity consumed by the battery can be supplemented, and the battery is not subjected to excessive current charging to cause damage to the battery.
Step S220, determining the trickle charge threshold value of the battery according to the trickle charge mode as a preset threshold value.
Specifically, when the current voltage is determined to be lower than the first preset voltage value, the battery is determined to be an overdischarge battery, and the battery is determined to adopt a trickle charge mode. The trickle charge mode is to charge the battery by a small current value and then increase the charge current when the electric quantity or voltage of the battery exceeds a certain value. And acquiring the trickle charge mode according to pre-stored data to determine a corresponding trickle charge threshold value, namely a preset threshold value. The trickle charge threshold is a very small current value, such as 300mA, which is a current value of 300mA per hour to charge the battery in an overdischarged state.
Further, the method for detecting the battery state of the present invention further includes:
step S41, when the current mode is not the charging mode, acquiring a minimum startup voltage or an automatic shutdown voltage of the battery;
specifically, when it is determined that the current mode of the battery is not the charging mode, the minimum startup voltage of the battery may be obtained by obtaining the minimum startup voltage of the battery when the battery is started, and the automatic shutdown voltage of the battery may be obtained when the battery is shut down. The automatic shutdown voltage comprises a standby automatic shutdown voltage or an automatic shutdown voltage in a call. The standby automatic shutdown voltage, the automatic shutdown voltage in the call or the minimum startup voltage are parameters for measuring the quality of the battery, and a manufacturer can detect whether the performance of the battery reaches the standard or not by detecting the parameters of the battery.
Step S42, judging whether the minimum starting voltage or the automatic shutdown voltage of the battery meets the preset voltage standard;
specifically, a pre-stored standard parameter of the battery, that is, a preset voltage parameter, is obtained, the minimum startup voltage or the automatic shutdown voltage of the battery is compared with the preset voltage standard parameter, and whether the minimum startup voltage or the automatic shutdown voltage is smaller than the preset voltage standard parameter is determined.
And step S43, when the minimum startup voltage or the automatic shutdown voltage does not meet the preset voltage standard, generating a corresponding battery abnormity prompting message.
Specifically, when the minimum startup voltage or the automatic shutdown voltage is greater than a preset voltage standard parameter, that is, the minimum startup voltage or the automatic shutdown voltage does not meet a preset voltage standard. And generating a corresponding reminding message to remind a user or a manufacturer that the startup or shutdown parameters of the battery do not meet the relevant requirements.
Further, the method for detecting the battery state of the present invention further includes:
step S51, calculating the state score of the battery according to the preset weight, the current charging current and the preset scoring rule;
specifically, according to the magnitude of the heat generation influence of the charging current mode on the battery, a corresponding preset weight is set, that is, the weight of the heat generation influence of the charging current mode on the battery is large. For example, in the constant current charging mode, the charging current is the largest, and the amount of heat generation is most likely to occur. Therefore, the charging current in the constant current charging mode has the largest influence on the heat generation of the battery, and the weight should be set to be the largest, such as 0.6. The charging current in the trickle charge mode is the smallest and most difficult to generate heat, i.e. the charging current in the trickle charge mode has the smallest influence on the battery heat generation, and the weight should be set to the smallest, e.g. 0.1. And multiplying the corresponding weight by each charging mode score to calculate the state score of the battery.
And step S52, generating corresponding state score reminding information according to the state score.
Specifically, the higher the state score of the battery is, the more the heat generation amount of the battery is, that is, the more the battery is prone to operating failure. And generating related battery state score reminding information when the battery state score is higher so as to remind a user that the battery is large in current heating, easily damages a terminal and needs to suspend charging.
