Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.

FIG. 1 is a flow chart illustrating a method of charge failure detection according to an exemplary embodiment; the method of the embodiment can be applied to first equipment, and the first equipment can be terminal equipment such as a smart phone, a tablet personal computer and the like, equipment with a charging function such as a charger and the like, or charging fault detection equipment and the like.

As shown in fig. 1, the method includes the following steps S101-S104:

in step S101, in response to detecting that the first device and the second device to be detected for faults are in a charging connection state, request information for detecting the charging faults of the second device is acquired.

In this embodiment, the first device may be a charging device or a charged device, and the first device may perform fault detection on the second device that is in a charging connection state with the first device. When the first device and the second device to be detected for fault detection are detected to be in a charging connection state, the first device can acquire request information for detecting the charging fault of the second device, and the request information can carry identification information and the like of the second device.

It will be appreciated that the number of second devices may be at least one, i.e. the first device may establish a charging connection with at least one second device and perform fault detection on the at least one second device.

For example, when the first device and the second device to be detected for the fault are in a charging connection state, the user may trigger request information for detecting the charging fault on the first device, and then the first device may obtain the request information.

In step S102, a target detection item of the second device is determined based on the request information.

In this embodiment, after the first device obtains the request information for detecting the charging failure of the second device, the target detection item of the second device may be determined based on the request information. Wherein the target detection item may include at least one of: voltage bus VBUS, preset data interface, supply voltage, charging protocol, charging current and charging power. For example, the target detection item may be determined based on a default option or based on a selection operation by the user. Specifically, the determining procedure of the target detection item of the second device may include at least the following case one and case two:

determining a target detection item of the second device based on a selection operation of a user;

1) A general procedure for determining a target detection item of a second device based on a selection operation of a user:

In response to detecting that the first device and the second device to be detected are in a charging connection state, acquiring request information for detecting the charging failure of the second device, wherein the request information carries identification information of the second device; displaying a detection item of the second device based on the identification information of the second device; in response to a selection operation by the user, a target detection item of the second device is determined.

2) Another general procedure of determining the target detection item of the second device based on the selection operation of the user:

in response to detecting that the first device and the second device to be detected for faults are in a charging connection state, displaying detection items of the second device; and generating request information in response to the selection operation of the user, wherein the request information carries the target detection item.

For example, when the first device and the second device to be detected are in a charging connection state, the first device may display at least one preset detection item for selection, and then the user may select one or more items from the at least one preset detection item as target detection items to be detected based on actual needs, so as to realize subsequent detection of the target detection items of the second device.

Secondly, determining a target detection item based on a preset default option;

1) A general process of determining a target detection item for a second device:

and responding to the detection that the first equipment and the second equipment to be detected are in a charging connection state, acquiring request information for detecting the charging failure of the second equipment, wherein the request information carries a target detection item.

2) Another general procedure for determining a target detection item for a second device:

the user only selects the second equipment needing fault detection, the first equipment determines target detection items according to default detection items, and each item in the target detection items is sequentially detected.

For example: a target detection item associated with the second device is determined based on a preset relationship table of devices and detection items.

For example, when the first device and the second device to be detected for faults are in a charging connection state, the first device may determine at least one preset detection item as a target detection item directly based on request information triggered by a user for detecting the faults of the second device, and sequentially detect the target detection item to output a fault detection result.

In step S103, the target detection item of the second device is detected, so as to obtain a fault detection result. In this embodiment, after the first device determines the target detection item of the second device based on the request information, the first device may detect the target detection item of the second device, to obtain a fault detection result.

If the target detection item is one item, fault detection can be performed according to a detection flow corresponding to the target detection item;

if the target detection item is a plurality of items, the detection process may include the following case one and case two:

case one: and detecting each item in turn according to the sequence selected by the user.

For example, when the detection sequence selected by the user is the voltage bus VBUS, the preset data interface, the power supply voltage, the charging protocol, the charging current and the charging power, the first device may detect the voltage bus VBUS in sequence according to the detection sequence, and finally detect the charging power.

It will be appreciated that in practical applications, different detection orders or the same detection order of the target detection items may be set for different second devices, which is not limited in this embodiment.

And a second case: each item is detected in turn in a default order.

For example, when the default sequence is the voltage bus VBUS, the preset data interface, the power supply voltage, the charging protocol, the charging current and the charging power, the first device may detect the voltage bus VBUS first and detect the charging power finally according to the detection sequence.

Optionally, after the first device determines the target detection item of the second device, a detection component corresponding to the target detection item may also be determined, so that the target detection item of the second device is detected based on the detection component, so as to obtain a fault detection result.

Wherein, the detection component corresponding to the target detection item can be determined based on the actual type of the target detection item. For example, if the target detection item is the voltage bus VBUS of the second device, the corresponding detection component may be an analog-to-digital conversion ADC module in the first device; if the target detection item is a preset data interface (such as TYPE-C) of the second device, the corresponding detection component may be a preset signal line in the first device.

In another embodiment, the above manner of detecting the target detection item of the second device to obtain the fault detection result may refer to the embodiments shown in fig. 2 to 7, which are not described in detail herein.

In step S103, the failure detection result is output.

In this embodiment, after the first device detects the target detection item of the second device to obtain the fault detection result, the fault detection result may be output in a text and/or voice broadcast manner. When the fault detection result is output, the fault detection result corresponding to each detection item can be output after the detection of each detection item is finished, or the fault detection result can be integrally output after the detection of all target detection items is finished.

For example, after the first device obtains the fault detection result of the second device, the fault detection result and/or a prompt message related to the fault detection result may be displayed on a screen associated with the first device, so that a user may know the fault detection result of the second device in time, which is beneficial to more quickly and accurately analyzing the cause of the charging fault.

The screen associated with the first device may include a screen of the first device itself or a screen of another device that may exchange data with the first device.

It should be noted that, the content of the prompt information may be set based on actual needs, for example, the prompt information may include at least one of the following:

(1) Prompting information of normal or abnormal fault detection results;

(2) And detection suggestion information matched with the current fault detection result.

As can be seen from the foregoing description, in the method of this embodiment, by responding to detection that the detection item display condition is satisfied, displaying at least one preset detection item, and responding to detection that an operation of selecting a target detection item to be detected from the at least one preset detection item is detected, detecting the target detection item of the second device based on a detection component corresponding to the target detection item, so as to obtain a fault detection result, where the second device is in a charging connection state with the first device, and further outputs the fault detection result, it is possible to implement efficient and convenient detection of the target detection item of the second device, and avoid machine disassembly detection of the second device, thereby avoiding loss of a bad site caused by machine disassembly, and being beneficial to more rapid and accurate analysis of the cause of the charging fault of the second device.

Fig. 2 is a flowchart showing how to detect a target detection item of a second device based on a detection means corresponding to the target detection item according to a first exemplary embodiment of the present disclosure; the present embodiment exemplifies how to detect the target detection item of the second device based on the detection section corresponding to the target detection item on the basis of the above-described embodiments. The object detection item may include VBUS, among others. On this basis, as shown in fig. 2, the detection of the target detection item of the second device in the step S103 to obtain a fault detection result may include the following steps S201 to S204:

in step S201, the VBUS voltage of the second device is detected based on a preset analog-to-digital conversion ADC module, so as to obtain a VBUS voltage value.

In this embodiment, after the first device determines that the target detection item of the second device is VBUS based on the request information, it may be determined that a detection component corresponding to the target detection item is an analog-to-digital conversion ADC module, and further, the VBUS voltage of the second device may be detected based on the ADC module, so as to obtain a VBUS voltage value of the second device.

In step S202, it is determined whether the VBUS voltage value is equal to a preset short circuit voltage threshold: if yes, go to step S203; if not, step S204 is performed.

In this embodiment, when the first device detects the VBUS voltage of the second device based on the preset analog-to-digital conversion ADC module to obtain a VBUS voltage value, the VBUS voltage value may be compared with a preset short circuit voltage threshold to obtain a comparison result, and if the comparison result is that the VBUS voltage value is equal to the short circuit voltage threshold, step S203 is executed; or if the VBUS voltage value is not equal to the short-circuit voltage threshold, step S204 is performed.

The above-mentioned short-circuit voltage threshold may be set based on actual needs, for example, set to 0V.

In step S203, it is determined that the fault detection result is that VBUS is shorted.

In step S204, it is determined that the fault detection result is VBUS that no short circuit occurs.

For example, after the first device compares the VBUS voltage value with a preset short-circuit voltage threshold, if it is determined that the VBUS voltage value is equal to 0V, it may be determined that the fault detection result is VBUS short-circuit. On this basis, the prompting information for prompting the VBUS to generate a short circuit may be selectively output, which is not limited in this embodiment.

In contrast, if it is determined that the VBUS voltage value is not equal to 0V, it may be determined that the fault detection result is VBUS is not shorted. On this basis, the prompting information for prompting that the VBUS does not have a short circuit may also be selectively output, for example, the VBUS does not see an anomaly, which is not limited in this embodiment. As can be seen from the foregoing description, in this embodiment, by detecting the VBUS voltage of the second device based on the preset analog-to-digital conversion ADC module, a VBUS voltage value is obtained, and whether the VBUS voltage value is equal to a preset short circuit voltage threshold is determined, further when the VBUS voltage value is equal to the short circuit voltage threshold, it is determined that the fault detection result is that the VBUS is short-circuited, and when the VBUS voltage value is not equal to the short circuit voltage threshold, it is determined that the fault detection result is that the VBUS is not short-circuited, so that whether the VBUS of the second device is short-circuited can be conveniently and efficiently detected, and an accurate basis can be provided for subsequently analyzing the cause of the charging fault of the second device.

FIG. 3 is a flowchart showing how to detect a target detection item of a second device based on a detection component corresponding to the target detection item, according to a second exemplary embodiment of the present disclosure; the present embodiment exemplifies how to detect the target detection item of the second device based on the detection section corresponding to the target detection item on the basis of the above-described embodiments. Wherein the target detection item may comprise a preset data interface. On this basis, as shown in fig. 3, the detection of the target detection item of the second device in the step S103 to obtain a fault detection result may include the following steps S301 to S304:

in step S301, the impedance to ground of the first signal line in the preset data interface of the second device is detected, so as to obtain an impedance value.

In this embodiment, after the first device determines, based on the request information, that the target detection item of the second device is a preset data interface, it may be determined that the detection component corresponding to the target detection item is a first signal line preset in the first device, and then, based on the first signal line, the impedance to ground of the first signal line in the preset data interface of the second device may be detected, so as to obtain the impedance value. It should be noted that the same type of first signal line is also disposed in the preset data interface of the second device.

Taking the TYPE-C interface as an example, the first signal line in the first device may be a CC line set in the first device in advance, and meanwhile, a CC line is also set in the preset data interface of the second device. The first device may be a fast charging device in the related art, and the charging device may support a PD protocol, and has a CC signal line therein, that is, the first device may measure the impedance to ground of the CC at the TYPE-C interface, so as to obtain an impedance value.

In step S302, it is determined whether the impedance value is outside the set normal impedance threshold range: if yes, go to step S303; if not, step S304 is performed.

In this embodiment, when the first device detects the impedance to ground of the first signal line at the TYPE-C interface of the second device based on the preset first signal line, after obtaining the impedance value, the impedance value may be compared with the set normal impedance threshold range to obtain a comparison result, and if the impedance value is outside the normal impedance threshold range, step S303 is executed; alternatively, if the impedance value is within the normal impedance threshold range, step S304 is performed.

The normal impedance threshold range may be set based on actual needs, for example, 1mΩ to 50mΩ, which is not limited in this embodiment.

In step S303, it is determined that the failure detection result is that connectivity between the preset data interface of the second device and the motherboard is abnormal.

In step S304, it is determined that the connectivity between the preset data interface of the second device and the motherboard is normal.

For example, after the first device compares the impedance value with the set normal impedance threshold range, if it is determined that the impedance value is outside the normal impedance threshold range, it may be determined that the connectivity between the preset data interface of the second device and the motherboard is abnormal as a result of the fault detection. On the basis, the method can also selectively output prompt information for prompting to check the connectivity between the preset data interface and the main board, such as 'TYPE-C interface is abnormal, please check the connectivity between TYPE-C interface and the main board', and the embodiment is not limited to this.

Conversely, if the impedance value is determined to be within the normal impedance threshold range, for example, the impedance value is detected to be 25mΩ, it may be determined that the connectivity of the preset data interface of the second device and the motherboard is normal as a result of the fault detection. On the basis, a prompt message for prompting that the connectivity between the preset data interface and the main board is normal, such as "no abnormality occurs in the TPYE-C interface", can also be selectively output, and the embodiment is not limited to this. As can be seen from the foregoing description, in this embodiment, by detecting the impedance to ground of the first signal line in the preset data interface of the second device, an impedance value is obtained, and when it is determined that the impedance value is outside the normal impedance threshold range, it is determined that the connectivity between the preset data interface and the motherboard is abnormal, and when it is determined that the impedance value is within the normal impedance threshold range, it is determined that the fault detection result is normal for the preset data interface, so that it is possible to conveniently and efficiently detect whether the preset data interface of the second device is normal, and further, it is possible to improve the accurate basis for subsequently analyzing the cause of the charging fault of the second device.

Fig. 4 is a flowchart showing how to detect a target detection item of a second device based on a detection means corresponding to the target detection item according to a third exemplary embodiment of the present disclosure; the present embodiment exemplifies how to detect the target detection item of the second device based on the detection section corresponding to the target detection item on the basis of the above-described embodiments. Wherein the target detection term may comprise a supply voltage. On this basis, as shown in fig. 4, the detection of the target detection item of the second device in the step S103 to obtain a fault detection result may include the following steps S401 to S404:

in step S401, a power supply voltage of the second device is detected based on a second signal line of the preset data interface of the first device, so as to obtain a power supply voltage value, where the second signal line supports a single-wire protocol.

In step S402, it is determined that the power supply voltage value is less than or equal to a preset voltage threshold: if yes, go to step S403; if not, step S404 is performed.

In step S403, it is determined that the failure detection result is that the power supply voltage does not support quick charge.

In step S404, it is determined that the failure detection result is that the power supply voltage supports quick charge.

In this embodiment, after the first device determines, based on the request information, that the target detection item of the second device is the power supply voltage, it may be determined that the detection component corresponding to the target detection item is a second signal line preset in the preset data interface of the first device, and further, the power supply voltage of the second device may be detected based on the second signal line, so as to obtain the power supply voltage value.

It should be noted that the second signal line may be a signal line MI (Mobile Information) provided in the first device in advance. Wherein the signal line MI is a single-wire protocol that is programmable to transmit power supply voltage information of the second device. It can be understood that, when the second device establishes a charging connection with the first device, that is, when there is a voltage on VBUS of the second device, the internal chip of the second device may transmit the current power supply voltage to the internal chip of the first device through the signal line MI, so as to perform a subsequent detection step.

Specifically, when the power supply voltage of the second device is detected based on a second signal line preset in a preset data interface of the first device, after a power supply voltage value is obtained, the power supply voltage value can be compared with a set fast charging power supply voltage threshold value, so as to obtain a comparison result, for example: whether the power supply voltage value is less than or equal to the fast charge power supply voltage threshold; alternatively, the power supply voltage value is greater than the fast charge power supply voltage threshold.

The fast charging power supply voltage threshold may be set based on actual needs, for example, set to 3.4V.

On this basis, when it is determined that the power supply voltage value is less than or equal to the rapid charging power supply voltage threshold value, it may be determined that the power supply voltage does not support rapid charging as a result of the fault detection. On this basis, a prompt message for prompting to wait for the increase of the power supply voltage, for example, a prompt message indicating that the power supply voltage is too low and quick charge is not supported, or a prompt message indicating to wait for the increase of the power supply voltage can be selectively output, which is not limited in this embodiment.

Conversely, if it is determined that the power supply voltage value is greater than the quick charge power supply voltage threshold, it may be determined that the failure detection result is that the power supply voltage supports quick charge. On this basis, a prompt message for prompting the power supply voltage to support the quick charging may be selectively output, for example, the power supply voltage supports the quick charging, please continue to check whether the charging current is normal, which is not limited in this embodiment. As can be seen from the foregoing description, in this embodiment, by detecting the power supply voltage of the second device based on the preset second signal line to obtain a power supply voltage value, comparing the power supply voltage value with a set fast charging power supply voltage threshold, further determining, in response to determining that the power supply voltage value is less than or equal to the fast charging power supply voltage threshold, that the power supply voltage does not support fast charging, and in response to determining that the power supply voltage value is greater than the fast charging power supply voltage threshold, determining that the power supply voltage supports fast charging, it is possible to implement convenient and efficient detection of whether the power supply voltage of the second device supports fast charging, and further, it is possible to implement a subsequent accurate analysis of the cause of the charging failure of the second device.

Fig. 5 is a flowchart showing how to detect a target detection item of a second device based on a detection means corresponding to the target detection item according to a fourth exemplary embodiment of the present disclosure; the present embodiment exemplifies how to detect the target detection item of the second device based on the detection section corresponding to the target detection item on the basis of the above-described embodiments. The VBUS of the first device is provided with a detection resistor, and the target detection item may include a charging current. On this basis, as shown in fig. 5, the detection of the target detection item of the second device in the step S103 to obtain a fault detection result may include the following steps S501 to S504:

in step S501, a charging current of the second device is detected based on the detection resistor, and a charging current value is obtained.

In this embodiment, after the first device determines, based on the request information, that the target detection item of the second device is the charging current, it may be determined that the detection component corresponding to the target detection item is a detection resistor (e.g., a Sense resistor) preset in the first device, and then the charging current of the second device may be detected based on the detection resistor, so as to obtain the charging current value.

It will be appreciated that by adding the Sense resistor described above to the internal VBUS of the first device, the magnitude of the charging current can be calculated by measuring the voltage across the Sense resistor.

In step S502, it is determined whether the charging current value is within a preset current threshold range: if yes, go to step S503; if not, step S504 is performed.

In this embodiment, when the charging current of the second device is detected based on the preset detection resistor, the charging current value may be obtained, and then the charging current may be compared with the preset current threshold range, and when it is determined whether the charging current value is within the preset current threshold range, step S503 is performed, and when it is determined whether the charging current value is outside the preset current threshold range, step S504 is performed.

In step S503, it is determined that the failure detection result is that the charging current of the second device is normal.

In step S504, it is determined that the failure detection result is that the charging current of the second device is abnormal.

For example, after the first device compares the charging current with the preset current threshold range, if it is determined that the charging current is within the preset current threshold range, it may be determined that the charging current of the second device is normal as a result of the fault detection. On the basis, a prompting message for prompting the normal charging current of the second device can also be selectively output, which is not limited in this embodiment.

In contrast, if it is determined that the charging current is out of the preset current threshold range, it may be determined that the fault detection result is that the charging current of the second device is abnormal. On the basis of this, a prompt message for prompting the abnormality of the charging current of the second device may also be selectively output, which is not limited in this embodiment.

As can be seen from the foregoing description, the present embodiment detects the charging current of the second device based on the detection resistor, so as to obtain a charging current value, and determines that the fault detection result is that the charging current of the second device is normal when the charging current value is within a preset current threshold range, and determines that the fault detection result is that the charging current of the second device is abnormal when the charging current value is outside the preset current threshold range, so that it is possible to conveniently and efficiently detect whether the charging current of the second device is normal, and provide an accurate basis for subsequently analyzing the cause of the charging fault of the second device.

Fig. 6 is a flowchart showing how to detect a target detection item of a second device based on a detection means corresponding to the target detection item according to a fifth exemplary embodiment of the present disclosure; the present embodiment exemplifies how to detect the target detection item of the second device based on the detection section corresponding to the target detection item on the basis of the above-described embodiments. The target detection term may include, among other things, a charging power. On this basis, as shown in fig. 6, the detection of the target detection item of the second device in the step S103 to obtain a fault detection result may include the following steps S601 to S605:

In step S601, an actual charging power of the second device is determined based on a product of the currently detected charging current of the second device and the VBUS voltage value.

For example, when the first device detects the charging current of the second device based on the preset detection resistor, and obtains the charging current value, the actual charging power of the second device, that is, the actual power of the first device for charging the second device, may be determined based on the product of the charging current and the VBUS voltage value of the second device.

The VBUS voltage value of the second device may be detected based on the analog-to-digital conversion ADC module in the embodiment shown in fig. 2, or may be detected based on other manners in the related art, where the obtained results are applicable to the subsequent steps of the embodiment, and the embodiment is not limited to this. The charging current of the second device may be detected based on the detection resistor in the embodiment shown in fig. 5, or may be detected based on other manners in the related art, and the obtained results are applicable to the subsequent steps of the embodiment, which is not limited in the embodiment.

In step S602, the maximum power that the first device needs to output is obtained from the second device, and a first difference between the maximum power and the actual charging power is determined.

In this embodiment, the maximum power required to be output by the first device may be obtained from the second device in advance, where the maximum power may be the maximum power required to be output by the first device obtained by performing calculation fitting on the second device based on information such as the power supply voltage of the second device and the current temperature, and a specific calculation fitting manner may refer to an existing scheme in the related art, which is not limited in this embodiment. On the basis of this, a difference between the maximum power and the actual charging power determined in the above step S502, that is, the above-described first difference, may be calculated.

In step S603, it is determined whether the first difference is greater than or equal to a preset power difference threshold: if yes, go to step S604; if not, step S605 is executed.

In this embodiment, after determining the first difference between the maximum power obtained in advance and the actual charging power, the first difference may be compared with a set power difference threshold to obtain a comparison result, for example: the first difference is greater than or equal to the power difference threshold; alternatively, the first difference is less than the power difference threshold.

The power difference threshold may be set based on actual needs.

In step S604, it is determined that the failure detection result is that the charging power of the second device is abnormal.

In step S605, it is determined that the failure detection result is that the charging power of the second device is normal.

In this embodiment, after the first device compares the first difference value with the set power difference value threshold, it may determine that the fault detection result is that the charging power is abnormal in response to determining that the first difference value is greater than or equal to the power difference value threshold. On the basis, the method can also selectively output prompt information for prompting that the charging power is abnormal and/or output prompt information for prompting that whether the charging chip is normal or not is continuously checked.

In contrast, if it is determined that the first difference is smaller than the power difference threshold, it may be determined that the failure detection result is that the charging power is normal. On this basis, a prompt message for prompting that the charging power is normal, for example, "the charging power is not abnormal" may be selectively output, which is not limited in this embodiment.

As can be seen from the foregoing description, in this embodiment, by determining the actual charging power of the second device based on the product of the charging current of the second device and the VBUS voltage value, then determining the difference between the maximum power required to be output by the first device obtained in advance and the actual charging power, and comparing the difference with a set power difference threshold, when it is determined that the difference is greater than or equal to the power difference threshold, it is determined that the charging power is abnormal, and when it is determined that the difference is less than the power difference threshold, it is determined that the charging power is normal, so that it is possible to conveniently and efficiently detect whether the charging power of the second device is normal, and further, it is possible to accurately analyze the cause of the charging failure of the second device.

Fig. 7 is a flowchart showing how to detect a target detection item of a second device based on a detection means corresponding to the target detection item according to a sixth exemplary embodiment of the present disclosure; the present embodiment exemplifies how to detect the target detection item of the second device based on the detection section corresponding to the target detection item on the basis of the above-described embodiments. The target detection item may include a charging protocol, among other things. On this basis, as shown in fig. 7, the detection of the target detection item of the second device described in the above step S103, to obtain a fault detection result, may include the following steps S701 to S707:

in step S701, the current charging protocol of the second device, the compatible charging protocol of the first device and the second device, and the maximum charging current under the compatible charging protocol are obtained based on the identification of the two charging protocols of the first protocol chip preset in the first device and the second protocol chip of the second device.

In step S702, it is determined whether the current charging protocol is the same as the compatible charging protocol: if not, go to step S703; if yes, go to step S704.

In step S703, it is determined that the failure detection result is that the current charging protocol of the second device is abnormal.

In step S704, a second difference between the maximum charging current value and the currently acquired charging current value of the second device is determined.

In step S705, it is determined whether the second difference is less than or equal to a set normal charging current difference threshold: if yes, go to step S706; if not, step S707 is executed.

In step S706, it is determined that the fault detection result is determined that the current charging protocol and the charging current are both normal.

In step S707, it is determined that the failure detection result is determined that the current charging protocol is normal, but the charging current is abnormal.

In this embodiment, after the first device determines, based on the request information, that the target detection item of the second device is a charging protocol, it may be determined that a detection component corresponding to the target detection item is a preset first protocol chip, and further, identification of a charging protocol of both sides may be performed based on the preset first protocol chip and the second protocol chip of the second device, so as to obtain a current charging protocol of the second device, a compatible charging protocol of the charging device and the second device, and a maximum charging current under the compatible charging protocol.

Further, after the first device obtains the current charging protocol of the second device and the charging protocol compatible with the second device, it may be determined whether the current charging protocol is the same as the compatible charging protocol; if the current charging protocol is not the same, the fault detection result can be determined to be abnormal; and if so, may continue to determine a difference between the maximum charging current value and the currently acquired charging current value of the second device.

The currently obtained charging current value of the second device may be detected based on the detection resistor in the embodiment shown in fig. 5, or may be detected based on other manners in the related art, where the obtained results are applicable to the subsequent steps of the embodiment, and the embodiment is not limited to this.

On the basis, the second difference value can be compared with a set normal charging current difference value threshold value to obtain a comparison result, and if the difference value is smaller than or equal to the normal charging current difference value threshold value; alternatively, the difference is greater than the normal charge current difference threshold.

The normal charging current difference threshold may be set based on actual needs.

Further, when the difference is determined to be less than or equal to the normal charging current difference threshold, it may be determined that the fault detection result is that both the present charging protocol and the charging current are normal. On the basis, the method can also selectively output prompt information for prompting that the current charging protocol and the charging current are normal, such as 'charging protocol is normal, charging current is normal', and the embodiment is not limited to the prompt information.

In contrast, if it is determined that the difference is greater than the normal charging current difference threshold, it may be determined that the failure detection result is that the charging protocol is normal but the charging current is abnormal. On this basis, a prompt message for prompting that the charging protocol is normal but the charging current is abnormal may also be selectively output, for example, if the charging protocol is normal but the charging current is abnormal, please check whether the internal charging chip is abnormal, etc., which is not limited in this embodiment.

As can be seen from the foregoing description, in this embodiment, by identifying, based on a preset first protocol chip and a second protocol chip of the second device, two charging protocols, a current charging protocol of the second device, a charging protocol compatible with the second device, and a maximum charging current under the compatible charging protocol are obtained, and in response to detecting that the current charging protocol is different from the compatible charging protocol, a fault detection result that the current charging protocol is abnormal is determined, and in response to detecting that the current charging protocol is the same as the compatible charging protocol, a difference value between the maximum charging current value and a charging current value of the currently obtained second device is determined, and then when determining that the difference value is less than or equal to the normal charging current difference value threshold, the current charging protocol and the charging current are both normal, and when determining that the difference value is greater than the normal charging current difference value threshold, the current charging protocol is normal but the charging current is abnormal is determined, it is possible to implement convenient and efficient detection of whether the current charging of the second device and the corresponding current charging protocol is improved according to the accurate cause of the subsequent fault.

The charging fault detection method of the present disclosure is described below by taking a first device as a charger and a second device as a smart phone as an example. The charger can sequentially detect the smart phone according to the following sequence of (1) to (5):

(1) A voltage bus VBUS;

when the charger is connected to the mobile phone, namely, after the charger and the mobile phone are in charging connection, the charger can sample and detect the voltage of the VBUS of the mobile phone through a preset ADC module, further, when the VBUS voltage is detected to be 0V, the VBUS inside the mobile phone is confirmed to have a short circuit to ground, and prompt information of 'please check whether a TVS tube of the VBUS is short-circuited' can be output. When the VBUS voltage is detected to be not 0V, the fact that the VBUS in the mobile phone is not in short circuit to the ground can be confirmed, and prompt information of 'the VBUS is not in short circuit' can be output.

(2) TYPE-C interface (preset data interface);

in this embodiment, the charger may be an android fast charger, which may support a PD protocol, and a CC signal line may be preset in the charger, so that the charger may measure the impedance to ground of the CC signal line at the joint of TYPE-C of the mobile phone. Further, when the impedance to ground of the CC signal line is measured to be infinite (for example, the impedance to ground is actually detected to be greater than 50mΩ), it may be confirmed that the TPYE-C interface of the mobile phone and the motherboard are in an open state, and a prompt message "please check connectivity between TYPE-C and the motherboard" may be output; if the impedance to the ground of the CC signal line is measured to be about 25MΩ, it can be confirmed that the TPYE-C interface and the motherboard of the mobile phone are not in an open circuit state, and a prompt message of "no abnormality in the impedance of the TPYE-C" can be output.

(3) Battery voltage (voltage);

in this embodiment, it is considered that some mobile phones are charged slowly or not, which is caused by the fact that the battery voltage (i.e. the above-mentioned power supply voltage) is too low. Therefore, in this embodiment, in order to read the battery voltage of the mobile phone, a MI (Mobile Information) signal line may be added to the TYPE-C interface of the charger, and the MI signal line is a single-wire protocol capable of supporting programming, so that the battery voltage information of the mobile phone may be transmitted. Furthermore, when the mobile phone is connected to the charger, that is, when there is a voltage on the VBUS of the mobile phone, the internal chip of the mobile phone can transmit the battery voltage of the current mobile phone to the internal chip of the charger through the MI signal line. On the basis, when the battery voltage is lower than 3.4V, the battery voltage of the mobile phone can be determined not to support quick charge, and prompt information of 'the battery voltage is too low and not to support quick charge' can be output, and the user can wait for the rising of the battery voltage; when the battery voltage is higher than 3.4V, the battery voltage of the mobile phone can be determined to support the quick charge, and prompt information of 'the battery voltage supports the quick charge' can be output, and whether the charging current is normal or not is checked.

(4) Charging current and charging power;

In this embodiment, a detection resistor (Sense resistor) may be added to VBUS inside the charger in advance, and then the magnitude of the charging current of the mobile phone may be calculated by measuring the voltages at two ends of the Sense resistor. Based on this, the current actual charging power of the mobile phone (i.e., the actual output power of the charger for charging the mobile phone) can be determined based on the product of the charging current and the VBUS voltage of the mobile phone. On the other hand, the charger can receive the 'maximum power required to be output by the current charger' transmitted by the mobile phone through the MI signal line, wherein the maximum power can be the maximum power required to be output by the charging equipment, which is obtained by calculating and fitting the information such as the power supply voltage, the current temperature and the like of the mobile phone terminal. On the basis, the charger can compare the actual charging power with the maximum power, and when detecting that the difference between the actual charging power and the maximum power is large (for example, the difference between the maximum power and the actual charging power is larger than or equal to a preset power difference threshold value), the charger can determine that the charging power of the mobile phone is abnormal, and can output corresponding prompt information, such as "the charging power is abnormal, please check whether the charging chip is normal", and the like; in contrast, the charging power of the mobile phone can be determined to be normal, and corresponding prompt information such as charging current and power are output.

(5) A charging protocol;

in this embodiment, after the mobile phone is connected to the charger, both parties can perform USB protocol identification based on the respective protocol chips, so that the charger can obtain the current charging protocol of the mobile phone, the compatible protocol of the charger and the mobile phone, and the maximum charging current under the compatible protocol. On the basis, if the current charging protocol of the mobile phone is detected to be different from the compatible protocol, the fact that the compatible charging protocol cannot be achieved due to the fault of the mobile phone circuit can be confirmed, and then prompt information of' whether the current protocol is abnormal or not and whether an internal charging chip is abnormal or not can be output. If the current charging protocol of the mobile phone is detected to be the same as the compatible protocol, and the current charging current of the mobile phone (namely, the charging current detected in the (4)) can reach the maximum charging current under the compatible protocol, the charging protocol and the charging current of the mobile phone can be confirmed to be normal, and then prompt information of normal protocol identification and normal charging current can be output.

It should be noted that the above detection sequence may be adjusted according to actual requirements, and is not limited to the detection sequence shown above.

According to the above description, the charging fault information of the mobile phone can be accurately detected through the scheme, and then the fault detection result and related prompt information can be output, so that research personnel or after-sales personnel can be helped to analyze the fault reason more efficiently and conveniently, the process of analyzing the charging fault reason can be faster and more convenient, the fault detection can be realized without disassembling the mobile phone, the loss of bad field phenomenon caused by disassembling the mobile phone can be avoided, and research personnel or after-sales personnel can be further helped to improve the fault analysis efficiency and quality.
