The electronic device may provide visual output related to touch operations, etc. through the display screen 140. In other embodiments, the touch sensor 150A can be disposed on a surface of the electronic device at a different location than the display screen 140.

It should be noted that, through the battery connector, the user can detach the battery in the electronic device as required, thereby facilitating the replacement of the battery.

It is to be understood that the illustrated structure of the embodiment of the present invention does not specifically limit the mobile phone 100. In other embodiments of the present application, the handset 100 may include more or fewer components than shown, or some components may be combined, some components may be separated, or a different arrangement of components may be used. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

Referring to fig. 2, fig. 2 is another schematic structural diagram of the mobile phone 100, where the mobile phone 100 includes a motherboard and a battery, where most of power consuming components on the mobile phone 100 shown in fig. 1 are integrated on the motherboard, and a USB interface is further integrated on the motherboard, specifically, the USB interface is a charging input interface, and the input electric energy can supply power to the motherboard. The battery is connected to the motherboard through one or more battery connectors (fig. 2 shows two battery connectors, a first battery connector and a second battery connector as an example, but the number of the battery connectors is not limited in this embodiment), and when the battery connectors between the battery and the motherboard are engaged, the battery can be charged by the electric energy input at the USB interface. In addition, the battery can also provide power for each power consuming component on the motherboard.

Referring to fig. 3, fig. 3 is a schematic structural diagram of a conventional battery connector. In fig. 3, the structure of the battery connector will be described by taking one battery connector in fig. 2 as an example.

The battery connector includes a first plug assembly (also referred to as a male connector) and a second plug assembly (also referred to as a female connector) that are snap-fitted to each other. The first plug-in component is provided with a protruded pin, the second plug-in component is provided with a hole-shaped pin, and the protruded pin on the first plug-in component is inserted into the hole-shaped pin on the second plug-in component, so that the first plug-in component and the second plug-in component are buckled. Certainly, the protruded pins on the first plug-in component and the hole pins on the second plug-in component may be in one-to-one correspondence, and the corresponding protruded pins and the hole pins need to be plugged together when being buckled. The first plug-in component is connected with the first device, and the second plug-in component is connected with the second device. The first plug-in component and the second plug-in component are buckled together, so that the battery connector is buckled, and the first device and the second device are connected.

In this embodiment, the first device may be a battery, the second device may be a motherboard, the first plug-in component is connected to the battery, the second plug-in component is connected to the motherboard, and the battery and the motherboard are connected by being fastened by the battery connector. Illustratively, the first plug assembly may include 3 protruding pins, and the 3 protruding pins may be respectively connected to the pair of positive and negative electrode tabs of the battery and the temperature sensor through extension lines, for example, the 3 protruding pins are pin 1, pin 2 and pin 3. Wherein, pin 1 is connected with the positive lug, pin 2 is connected with the negative lug, and pin 3 is connected with the temperature sensor. Correspondingly, the second plug-in component is provided with hole-shaped pins which are in one-to-one correspondence with the 3 protruding pins of the first plug-in component. 3 protruding pins of the first plug assembly are plugged with 3 hole-shaped pins of the second plug assembly, so that the battery connector is buckled, and meanwhile, the connection between the battery and the mainboard is realized.

Pin 1 and pin 3 are used to transmit current between the interconnected battery and the motherboard, and current flows from the battery to the motherboard when the motherboard is powered by the battery, for example. When an external charger (such as a power adapter) charges a battery, the power adapter is plugged into a USB interface, the USB interface is integrated on a mainboard, and current flows into the battery from the power adapter through the USB interface and the mainboard to charge the battery. Pin 2 is used to transmit a temperature signal to a processor on the motherboard.

It should be noted that the pins shown in fig. 3 are only examples, and the pins of the battery connector in the embodiment of the present application may include more or fewer pins, for example, there may be no pin for connecting a temperature sensor, or an identification pin of a battery may also be included.

At present, an efficient charging scheme for electronic devices is a multi-tab charging manner, that is, a battery cell has multiple pairs of tabs (fig. 2 illustrates 2 pairs of tabs, but the number of pairs of tabs is not limited in the embodiment of the present application), where the multiple pairs of tabs may be one or more positive tabs sharing one negative tab, or may be mutually independent (not shown in fig. 2) pairs of tabs.

In practical applications, in order to disperse current and improve thermal balance, as shown in fig. 2, each pair of tabs is connected to the main board through an independent battery connector, and the charging current is increased by charging a plurality of pairs of tabs, thereby improving charging efficiency.

Although the charging efficiency is improved by the multi-lug charging mode, more battery connectors are introduced, and the buckling state of the battery connectors plays a crucial role in normal charging and discharging operations of the mobile phone. For the rechargeable battery of many battery connectors, the structure of the rechargeable battery of monocell connector is simple relatively, when single battery connector lock is bad, for example, external force striking etc. lead to battery connector lock not hard up, lead to the power supply line contact between mainboard and the battery not good, the cell-phone battery can't be for the mainboard power supply under this condition, the cell-phone can't be started, the user can't continue to use, this kind of condition just needs in time to overhaul, avoid the battery to use for a long time under battery connector lock abnormal state, cause the damage of battery or mainboard. Different from a single battery connector, the rechargeable battery with multiple battery connectors can still start the mobile phone to operate even if a certain battery connector is not well buckled, but a certain battery connector is not well contacted for a long time, so that a large potential safety hazard is caused. At present, a method for detecting poor buckling of each battery connector in a multi-tab charging mode does not exist.

In view of this, the present application provides a method for detecting a multi-battery connector buckling state, which may be applied to an electronic device, where a plurality of battery connectors are connected between a battery of the electronic device and a motherboard, and for each battery connector of the plurality of battery connectors, a value of one or more preset parameters related to the battery connector is respectively obtained, and if it is determined that the value of the one or more preset parameters respectively satisfies a preset detection condition corresponding to the one or more preset parameters, it is determined that the battery connector is normally buckled; and if the value of any one of the one or more preset parameters is determined not to meet the preset detection condition corresponding to any one preset parameter, determining that the battery connector is abnormally buckled, so as to detect the buckling state of the battery connector. Furthermore, the voltage and/or the temperature of the USB interface related to the battery connector can be detected in the charging process of the electronic equipment, so that the problem that the battery connector is not well buckled to cause larger loss is avoided.

The method for detecting a snap-fit state of a multi-cell connector according to the embodiments of the present application will be described in detail with reference to the following embodiments and accompanying drawings.

Fig. 4 is a flowchart illustrating a method for detecting a snap-fit state of a multi-battery connector according to an embodiment of the present disclosure. The method can be applied to the electronic device shown in fig. 1 and the structure shown in fig. 2, and mainly comprises the following steps:

for each battery connector (battery connector) in the electronic device, a processor in the electronic device obtains values of one or more preset parameters of the battery connector, step 401.

First, the structure of the electronic device shown in fig. 2 is taken as an example to describe parameters that may be applied in the present application.

1) A battery temperature;

in this embodiment, a temperature sensor is installed near the connection position of each battery connector and the battery, and the temperature sensor may be, for example, an ntc thermistor, or other temperature sensors. For convenience of description, ntc is exemplified below.

As shown in fig. 2, ntc1 is mounted near the first battery connector, ntc2 is mounted near the second battery connector, ntc1 is used to acquire the temperature near the first battery connector on the battery, ntc2 is used to acquire the temperature near the second battery connector on the battery, and the temperature acquired by ntc1 for the first battery connector and the temperature acquired by ntc2 for the second BTB are denoted Tbtb1 and Tbtb2, respectively. Ntc is actually mounted near the connection of the battery connector to the battery, so the temperature of the battery connector referred to herein is actually the temperature near the battery connector connected to the battery, i.e., Tbtb1 is the temperature near the first battery connector on the battery, and Tbtb2 is the temperature near the second battery connector on the battery, i.e., the temperature of the battery.

2) A battery voltage;

the battery voltage refers to the voltage between the positive electrode tab and the negative electrode tab of the battery. As will be understood from fig. 2, the voltages between the positive tab and the negative tab measured at the upper and lower ends of the battery connector with respect to the battery are both battery voltages, and may also be referred to as terminal voltages at which the battery connector is connected to the battery.

With continued reference to fig. 2, the battery voltage measured by the first battery connector is the voltage across the positive tab 1 and the negative tab, and the battery voltage measured by the second battery connector is the voltage across the positive tab 2 and the negative tab. The battery voltage measured by the first battery connector will be denoted Vbtb1 and the battery voltage measured by the first battery connector will be denoted Vbtb2 as follows.

3) USB interface voltage

The USB interface voltage refers to an input voltage of the USB interface, for example, after one end of the power adapter is connected to a power supply, for example, 220V commercial power, and the other end of the power adapter is plugged into the USB interface, the voltage of the USB interface is denoted as Vusb.

4) Temperature of USB interface

Referring to fig. 2, an ntc thermistor, labeled ntc3, is mounted at the USB interface, and the collected temperature is labeled Tusb at ntc 3. In fact, since some parts of the USB interface can be exposed outdoors, the temperature collected at ntc3 is also close to room temperature.

5) Battery specification mark

The battery specification identification is used for uniquely identifying one battery specification, each battery specification corresponds to one group of charging parameters, and the charging parameters mainly comprise: battery capacity, rated charging voltage, rated charging current, rated electric power, and the like. These parameters are typically battery factory parameters. As shown in fig. 2, the pins of the battery connector may further include a battery specification identification pin, and when the battery connector is fastened, the processor may obtain the battery specification identification through the battery specification identification pin.

As follows, the structure shown in fig. 2 is taken as an example for description, and the preset parameters of the embodiment exemplarily include but are not limited to some or all of the following: tbtb1, Tbtb2, Vbtb1, Vbtb2, Vusb, Tusb, or battery specification identification.

The first possible implementation manner of the processor obtaining the preset parameters is as follows: the processor synchronously acquires a plurality of preset parameters in a parallel manner; it should be understood that the detection methods are different, the preset parameters may be different, and the synchronous acquisition of multiple preset parameters refers to preset parameters agreed in a specific detection method, for example, a detection method only detects Tbtb1, Tbtb2, Vbtb1, Vbtb2, and a processor in the electronic device may synchronously acquire Tbtb1, Tbtb2, Vbtb1, Vbtb2, and synchronously detect whether each acquired preset parameter is a normal value or not according to the acquired parameters respectively and using corresponding judgment conditions.

Specifically, in the software level, the parallel mode may be implemented by a plurality of threads of one process, and each thread is used to collect one preset parameter. Or for the multi-core electronic device, the method can also be implemented by a plurality of processes, that is, each core executes one process, and one process is used for collecting one preset parameter, so that the parallel collection of a plurality of preset parameters is realized. Through the design, the electronic equipment can synchronously detect a plurality of preset parameters, and the detection efficiency can be improved.

A second implementable way for the processor to obtain the preset parameters is: in a serial acquisition mode, the processor acquires one preset parameter at a time according to a preset detection process, or acquires the current preset parameter to be detected, detects the next preset parameter to be detected after determining that the parameter is a normal value until all the preset parameters to be detected are detected, and exits the detection process if the current acquired preset parameter does not accord with preset detection conditions, for example, the value of the parameter is not within a normal threshold range, so that the next preset parameter does not need to be acquired.

For example, an exemplary predetermined detection procedure is: first detecting whether Tbtb1 is a normal value, followed by detecting whether Tbtb2 is a normal value, then detecting whether Vbtb1 is a normal value, and finally detecting whether Vbtb2 is a normal value, i.e., the detection order is Tbtb1 → Tbtb2 → Vbtb1 → Vbtb 2. Correspondingly, during detection, the electronic device may first collect Tbtb1, obtain Tbtb2 after determining Tbtb1 as a normal value, obtain Vbtb1 after determining Tbtb2 as a normal value, and so on until Vbtb2 is detected as a normal value. If the Tbtb1 is collected, it is determined that Tbtb1 is not within the normal range, the detection process can be exited, and Tbtb2, Vbtb1 and Vbtb2 do not need to be acquired, thereby reducing the resource overhead of collecting parameters.

A third implementable way for the processor to obtain the preset parameters is: for example, for some preset parameters that must be acquired, the preset parameters may be acquired in a parallel acquisition manner, and other parameters may be acquired in a serial acquisition manner. For example, Tbtb1 and Tbtb2 may be collected synchronously, and subsequently, when Tbtb1 and Ttbt2 are determined to be normal values respectively, a next parameter to be detected, for example, the voltage Vusb of the USB interface, is collected sequentially and then detected subsequently. Through the design, the detection time can be saved, the detection efficiency is improved, the waste of detection resources can be avoided, and the detection flexibility is higher.

It should be understood that if the acquisition mode is a serial acquisition mode, step 401 needs to be repeated, but the preset parameters for each acquisition are different.

Step 402, the processor respectively judges whether the values of the one or more preset parameters respectively meet preset detection conditions of the one or more preset parameters according to the acquired values of the one or more preset parameters for each battery connector; if the battery connector and the battery connector are all met, determining that the battery connector is normally buckled; otherwise, determining that the battery connector is abnormally buckled.

The method for detecting the snap-fit state of a multi-battery connector provided by the present application is described below with reference to specific embodiments. The detection method provided by this embodiment may start the detection process when the processor detects that the electronic device is powered on, or each time the processor detects that the electronic device is charged.

Example one

Referring to fig. 5a, fig. 5a is a flow chart illustrating a first method for detecting a snap-fit state of a multi-battery connector according to the present embodiment. The method comprises the following steps:

step 501 a: the processor obtains a voltage value Vbtb1 for the first battery connector.

Step 502 a: the processor determines whether Vbtb1 is within a normal voltage threshold range (denoted as a first preset threshold range), if so, performs step 503, otherwise, determines that the first battery connector is abnormally buckled.

It should be noted that the normal voltage threshold ranges corresponding to different battery connectors may be different or the same. For convenience of description, the threshold value or the threshold value range of each parameter corresponding to each battery connector is described as an example. For example, the normal voltage threshold range corresponding to the first battery connector and the normal voltage threshold range corresponding to the second battery connector may both be the first preset threshold range, and the similar points will not be described again.

Optionally, if the voltage value of the battery connector is not within the first preset threshold range, it indicates that the battery connector is abnormally buckled. Furthermore, if the voltage value of the battery connector is not within the first predetermined threshold range, and the first predetermined threshold range does not include 0V, it can be further determined whether the voltage value of the battery connector approaches 0V, for example, if Vbtb1 is less than or equal to 0, it indicates that the conductive loop formed by the positive tab 1 and the negative tab in the first battery connector is in an open circuit state.

Step 501 b: the processor obtains the voltage value Vbtb2 for the second battery connector.

Step 502 b: the processor determines whether Vbtb2 is within a first preset threshold range (as described above, it is assumed that the normal voltage threshold range corresponding to the second battery connector is the first preset threshold range), if so, step 503 is executed, otherwise, it is determined that the second battery connector is abnormally buckled.

When the electronic device includes a plurality of battery connectors, the voltage detection process of each battery connector can refer to the specific implementation steps of steps 501a to 502a, in this embodiment, the voltage detection method of the second battery connector is the same as that of the first battery connector, and the description of steps 501a to 502a refers to steps 501b to 502b, and the description is not repeated here.

Step 501 c: the processor obtains the voltage Vusb of the USB interface.

Step 502 c: the processor determines whether Vusb is within a normal voltage threshold range (denoted as a second preset threshold range) corresponding to the USB, if yes, step 503 is executed, otherwise, it is determined that the USB interface is abnormal.

Similarly, the voltage detection method of the USB interface is similar to the voltage detection method of the battery connector, and is not described herein again.

Step 503: the processor determines whether a voltage difference between the first battery connector and the second battery connector (marked as a first voltage difference) is smaller than a first preset threshold, and if so, executes step 504; otherwise, determining that the first battery connector is abnormally buckled or the second battery connector is abnormally buckled.

Specifically, the first voltage difference value is | Vbtb1-Vbtb2|, where | | | represents an absolute value, and if | Vbtb1-Vbtb2| ≧ a first preset threshold, it is determined that the first battery connector is in engagement abnormality or the second battery connector is in engagement abnormality, and the processor may also stop the detection of the plurality of battery connectors.

It should be understood that, in theory, during the charging process of the battery, the voltage values and the temperature values of the first battery connector and the second battery connector are the same, but due to process differences, such as different lengths of wires, different welding processes, unstable fastening states, etc., there may be a difference between the voltages of the first battery connector and the second battery connector, but the difference is generally small, and if the difference is large, such as the first voltage difference is greater than a first preset threshold, it indicates that the fastening of at least one of the two battery connectors is abnormal.

Step 504: the processor determines whether a voltage difference (marked as a second voltage difference) between the first battery connector and the USB interface is smaller than a second preset threshold, and if so, executes step 505; otherwise, determining that the first battery connector is buckled abnormally.

Specifically, the second voltage difference is | Vusb-Vbtb1|, and if | Vusb-Vbtb1| > or equal to the second preset threshold, it indicates that the first battery connector is abnormal, and the processor may exit the detection process of the plurality of battery connectors.

As will be appreciated by those skilled in the art, the input voltage of the USB interface needs to be dropped to supply power to the battery, and therefore, during the charging process, there is a certain voltage difference between Vusb and Vbtb1 and Vusb and Vbtb 2. For example, if the input voltage is 10V and the voltage drop coefficient is 0.5, the voltage of the battery connector is 10V × 0.5V — 5V. Theoretically, the voltage difference is a theoretical voltage drop value calculated from the voltage drop coefficient and the input voltage of the USB interface, and actually, the voltage difference may also include a voltage drop value caused by line loss between the USB interface and the battery connector. The second preset threshold provided by this embodiment may be determined according to a theoretical voltage drop value between the input voltage of the USB interface and the voltage of the battery connector, or determined according to both the theoretical voltage drop value and a voltage drop value caused by line loss.

Step 505: the processor judges whether a voltage difference value (recorded as a third voltage difference value) between the second battery connector and the USB interface is smaller than a second preset threshold value, if so, the first battery connector and the second battery connector are normally buckled; otherwise, determining that the second battery connector is buckled abnormally.

Specifically, the third voltage difference value is | Vusb-Vbtb2|, and if | Vusb-Vbtb2| > or equal to a second preset threshold, it indicates that the second battery connector is abnormally buckled.

When the electronic device includes a plurality of battery connectors, the voltage detection process of each battery connector can be referred to the above description of step 504, in the first embodiment, the voltage detection method of the second battery connector is the same as that of the first battery connector, and the execution process of step 505 refers to the detailed description of step 504, and the description is not repeated here.

It should be noted that (1) there is no strict time sequence limitation between step 501a to step 502a, step 501b to step 502b, and step 501c to step 502c, the voltage detection may be performed in parallel or in series, which is taken as an example of parallel execution, but the present application is not limited thereto, for example, referring to fig. 5b, which is a flow chart of a method for serially detecting a voltage, the specific implementation manner of each step in fig. 5b can be referred to as the specific description in fig. 5a, and is not described herein again, in addition, fig. 5b is only an example, and there are various ways of serially detecting the voltage in the embodiment of the present application, for example, step 503 may be executed after step 502b, or after the step 503, the step 501c is executed, after the step 501c, the step 502c is executed, after the step 502c, the step 504 is executed, and the like, which are not limited in the embodiment of the present application. (2) The method for detecting the engaging state of the battery connector by voltage is only an example, wherein the

steps

501c, 502c, 504 and 505 are optional steps, and the method for detecting the engaging state of the battery connector by voltage is not limited in this embodiment.

In addition, the preset values corresponding to the parameters involved in the above determination steps may be uniform, or may be configured according to different battery specifications. For example, a mapping relationship between the battery specification identifier and a normal value range of each parameter is preset in the electronic device, the electronic device may obtain the battery specification identifier through a pin of the battery connector, and query a threshold or a threshold range corresponding to each parameter corresponding to the battery specification identifier through the mapping relationship, where the values may be agreed by a protocol or determined according to an empirical value, an experimental value, and the like, which is not limited in this embodiment. See table 1 below for a specific example of a mapping relationship provided in the present embodiment.

TABLE 1

For example, after detecting a trigger condition (the trigger condition refers to the foregoing description, and may be when the processor detects that the electronic device where the processor is located is powered on, or when the processor detects that the electronic device where the processor is located is charged every time), the processor in the electronic device obtains the battery specification identifier, and determines, according to table 1, each parameter value corresponding to the battery specification identifier and the corresponding different preset threshold value ranges. And subsequently, judging the buckling state of the battery connector according to the parameter values.

In the above mode, the lock state of the battery connector can be detected through the voltage of the battery connector and the voltage of the USB interface, if the voltage is not accordant with the preset detection condition, the lock state of the battery connector is determined to be abnormal, further, a user can be timely informed that the lock state of the battery connector is abnormal, the influence on electronic equipment is reduced, and the safety accident caused by small hidden danger is avoided.

Example two

Referring to fig. 6a, fig. 6a is a flow chart illustrating a second method for detecting a snap-fit state of a multi-battery connector according to the present embodiment. The method comprises the following steps:

step 601 a: the processor obtains the temperature Tbtb1 of the first battery connector.

Step 602 a: the processor determines whether Tbtb1 is within a normal temperature threshold range (denoted as a third preset threshold range) corresponding to the first battery connector, if yes, step 603 is executed, otherwise, it determines that the first battery connector is abnormally buckled.

The normal temperature threshold ranges for different battery connectors may be different or the same. For convenience of description, the threshold value or the threshold value range of each parameter corresponding to each battery connector is described as an example. For example, the normal temperature threshold range corresponding to the first battery connector and the normal temperature threshold range corresponding to the second battery connector are both the third preset threshold range, and the similar points will not be described repeatedly below.

Optionally, if the temperature of the battery connector is not within the third preset threshold range, it indicates that the battery connector is abnormally fastened. Furthermore, if the temperature value of the battery connector is not within the third preset threshold range, it may be determined whether the temperature value of the battery connector is an open-circuit value and/or a short-circuit value. It should be understood that the measurement range of the temperature sensor is fixed, and the measurement value of the temperature sensor exceeds the measurement specification whether open or short, for example, the value of the temperature sensor is particularly low when short and high when open.

Step 601 b: the processor obtains the temperature Vbtb2 of the second battery connector.

Step 602 b: the processor determines whether Vbtb2 is within the normal threshold range corresponding to the second battery connector (as described above, it is assumed that the normal threshold range corresponding to the second battery connector is the third preset threshold range), if so, step 603 is executed, otherwise, it is determined that the fastening of the second battery connector is abnormal.

Step 601 c: the processor obtains the temperature Tusb of the USB interface.

Step 602 c: the processor determines whether the temperature Tusb of the USB interface is within a normal temperature threshold range (recorded as a fourth preset threshold range), if so, performs step 603, otherwise, determines that the USB interface is abnormal.

Here, the temperature of the USB interface is close to the room temperature, and therefore, the fourth preset threshold range may be determined according to the threshold range of the ambient temperature.

Step 603: the processor determines whether the temperature difference (recorded as the first temperature difference) between the first battery connector and the second battery connector does not exceed a third preset threshold, and if so, executes step 604; otherwise, determining the fastening abnormality of the first battery connector or the fastening abnormality of the second battery connector.

Specifically, the first temperature difference value is | Tbtb1-Tbtb2|, and if | Tbtb1-Tbtb2| ≧ a third preset threshold, it is determined that the first battery connector is in an abnormal engagement state or the second battery connector is in an abnormal engagement state, and the processor may also stop the detection of the plurality of battery connectors.

Step 604: the processor determines whether the temperature difference (recorded as a second temperature difference) between the first battery connector and the USB interface does not exceed a fourth preset threshold, and if so, executes step 604; otherwise, determining that the first battery connector is abnormally fastened.

Specifically, the second temperature difference is | Tbtb1-Tusb |, and if | Tbtb1-Tusb | ≧ the fourth preset threshold, it is determined that the first battery connector is abnormally fastened, and the processor may exit the detection procedure for the plurality of battery connectors.

Step 605: the processor judges whether a temperature difference (recorded as a third temperature difference) between the second battery connector and the USB interface does not exceed a fourth preset threshold value, and if so, the first battery connector and the second battery connector are normally buckled; otherwise, determining that the second battery connector is abnormally buckled.

Specifically, the third temperature difference is | Tbtb2-Tusb |, and if | Tbtb2-Tusb | ≧ a fourth preset threshold, it is determined that the second battery connector is abnormally engaged.

It should be noted that (1) there is no strict timing limitation between step 601a to step 602a, step 601b to step 602b, and step 601c to step 602c, the temperature detection may be performed in parallel or in series, which is taken as an example, but the present application is not limited thereto, for example, referring to fig. 6b, which is a flow chart of a method for serially detecting temperature, the specific implementation manner of each step in fig. 6b can be referred to as the specific description in fig. 6a, which is not described herein again, in addition, fig. 6b is only an example, and there are various ways of serially detecting the temperature in the embodiment of the present application, for example, step 603 may be executed after step 602b, or step 601c is executed after step 603, step 602c is executed after step 601c, step 604 is executed after step 602c, and the like, which is not limited in the embodiment of the present application. (2) The method for detecting the engaging state of the battery connector by temperature is only an example, wherein the

steps

601c, 602c, 604 and 605 are optional steps, and the method for detecting the engaging state of the battery connector by temperature is not limited in this embodiment.

Similarly, the preset values corresponding to the parameters involved in the determining steps in the second embodiment may be uniform, or may be configured according to different battery specifications. Exemplarily, see the following table 2, which is a specific example of another mapping relationship provided in the present embodiment.

TABLE 2

For example, after detecting a trigger condition (the trigger condition refers to the foregoing, and may be when the processor detects that the electronic device is powered on, or when the processor detects that the electronic device is charged each time), the processor in the electronic device obtains the battery specification identifier, and determines, according to table 2, each parameter value corresponding to the battery specification identifier and the corresponding different preset threshold ranges. And subsequently, judging the buckling state of the battery connector according to the parameter values.

According to the mode, the buckling state of the battery connector can be detected through the temperature of the battery connector and the temperature of the USB interface, if the temperature is not accordant with the preset detection condition, the buckling state of the battery connector is determined to be abnormal, further, a user is timely informed that the buckling state of the battery connector is abnormal, the influence on electronic equipment is reduced, and the safety accident is avoided.

EXAMPLE III

Another way to implement this is that the electronic device performs the first embodiment and the second embodiment serially, for example, the electronic device performs the steps of fig. 5b first, and then performs the steps of fig. 6 b. For another example, the electronic device performs the steps of fig. 6b first and then performs the steps of fig. 5 b. For another example, the electronic device performs the steps of fig. 5a, then performs the steps of fig. 6a or fig. 6b, and so on.

Exemplarily, see the following table 3, which is a specific example of another mapping relationship provided in the present embodiment.

TABLE 3

It should be noted that, the above lists are only examples, and the preset threshold ranges or the preset thresholds corresponding to different parameters may be completely the same, may also be partially the same (or not completely the same), or completely different, for example, a 1-a 2 may be 4 to 10, a 3-a 4 may also be 4 to 10, a 1-a 2 may be 4 to 10, a 3-a 4 may be 4 to 8, a 1-a 2 may be 4 to 7, and a 3-a 4 may be 8 to 10, which is not limited in this application embodiment, and of course, the specific values listed are also only examples, and are not limited in this application embodiment.
