step S101: and presetting a current corresponding relation between the charging circuit and the standard charging current.
Specifically, in the present embodiment, when only one charging circuit is present in the electronic device, one standard charging current may be set in advance in the memory. When a plurality of charging circuits are present in the electronic device, a charging current corresponding to each charging circuit is set in the memory. For example, in the POS machine, there are a usb charging mode and a cradle charging mode, that is, there are two different charging circuits of a usb charging circuit and a cradle charging circuit, and the standard charging currents of the two different charging circuits are preset, for example, the standard charging current of the usb charging circuit is set to 300mA, and the standard charging current of the cradle charging circuit is set to 1000 mA. It should be understood that the foregoing is only an example of a specific application of the current correspondence relationship between the charging circuit and the standard charging current provided in the present embodiment, and is not limited thereto, and in other embodiments of the present invention, other types of charging circuits, such as wireless charging, may be provided.
Step S102: an actual charging circuit is obtained.

When the actual charging circuit is obtained, the actual charging node value is obtained, and the actual charging circuit can be obtained according to the corresponding relation between the actual charging node value and the node value.
Further, in this embodiment, a charging node value of each charging circuit is set in a charging information storage file, for example, an mtk _ chg _ type _ det.c file, in advance, when the electronic device is connected to a charger to perform charging, the charging information storage file obtains charging information reported by the charging interface, and when an upper application function in the system calls a function in the charging information storage file, the charging information storage file returns the charging node value to the upper application function, so that the system can obtain an actual charging circuit according to a correspondence between the charging node value and the node value.
Step S103: and acquiring the actual charging current.
Specifically, in the present embodiment, after the actual charging circuit is obtained, at least one current node in the actual charging circuit is obtained, and the actual charging current is obtained through the current node.
Further, in this embodiment, when the charger is connected, that is, when the charger provides a voltage to the charging module, a charging interrupt signal is generated to the CPU to notify the CPU that the charging module has now entered a charging state, the CPU starts ADC sampling to mainly collect Vchag, Vbat and a voltage output from a current node in the actual charging circuit, and the charging current can be calculated by the collected voltage and a resistance value of a resistor connected between the three nodes.
Step S104: a standard charging current corresponding to the actual charging circuit is acquired as a reference charging current.
Specifically, in the present embodiment, a standard charging current corresponding to the actual charging circuit is acquired from a preset current correspondence relationship as a reference charging current.
Step S105: and judging whether the difference value between the actual charging current and the reference charging current is larger than a preset threshold value, if so, executing the step S106, and if not, ending the fault detection process.
Specifically, in this embodiment, the preset threshold is a preset current difference threshold, and in the actual use process, the preset threshold can be flexibly set according to actual needs, for example, when the accuracy of fault detection needs to be improved, the preset threshold can be set to be a smaller value, and when the efficiency of fault detection needs to be improved, the preset threshold can be set to be a larger value. It should be understood that the foregoing is only an example of a specific application of the setting of the preset threshold in this embodiment, and is not limited thereto, and in other embodiments of the present invention, the setting may also be performed according to other requirements, for example, when the standard charging current value is relatively large, the fluctuation of the current is relatively large, the preset threshold may be set to be a relatively large value, when the standard charging current value is relatively small, the fluctuation of the current is relatively small, and the preset threshold may be set to be a relatively small value.
