Brief description of the drawings
By reading the detailed description made to non-limiting example made with reference to the following drawings, the application's is other
Feature, objects and advantages will become more apparent upon：
Fig. 1 is battery fault detection method flow chart in the present invention.
Embodiment
The application is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched
The specific embodiment stated is used only for explaining related invention, rather than the restriction to the invention.It also should be noted that, in order to
It is easy to illustrate only the part related to invention in description, accompanying drawing.
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the application can phase
Mutually combination.Describe the application in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
Fig. 1 is refer to, the present invention provides a kind of battery fault detection method, and methods described includes：
Detect battery capacity information Cn；
Calculate the battery capacity difference △ C detected twice(n), △ C(n)=Cn-Cn+1；
Battery capacity difference is compared with predetermined threshold value, battery status is shown according to comparison information.
Detection method in the application detected and compared to electricity of battery when fully charged, and battery uses it for the first time
Charged afterwards, the battery capacity and the full capacitance of battery that will be filled with electricity are compared；Using for the second time and later expires battery
Capacitance with it is preceding once expire capacitance compared calculating difference, the difference of battery capacity and predetermined threshold value are compared, according to than
Compared with the state that situation judges battery, prevent battery from the situation of power-off or low battery suddenly occurring in use.
Further, the battery capacity when battery capacity information is fully charged per primary cell.When battery is fully charged
The capacity of battery is detected and compared, can find whether the battery is capable of the change of the fully charged and battery capacity in time
Whether there is exception, further show whether battery occurs in that abnormal conditions.
Further, if battery capacity difference is less than predetermined threshold value, alarm and show that battery status is malfunction
Or the life-span is compared with short status；Otherwise it is normal condition to show battery status.
If battery capacity difference is less than predetermined threshold value, i.e., the rear full capacitance decline of one-shot battery is larger, and now battery may be sent out
Raw failure or life-span are shorter, it is necessary to be changed to battery, warning reminding user；This method of testing is more directly perceived and simple
It is single, the replacing for instructing battery of science.
The present invention also provides a kind of terminal, including battery capacity detection module, for detecting battery capacity information Cn；
Logging modle, the battery capacity C for receiving the battery capacity detection module detectionnAnd recorded；
Computing module, for calculating battery capacity difference △ C(n), △ C(n)=Cn-Cn+1；
Comparison module, is compared for the poor threshold value of preset battery capacity, and by battery capacity difference with predetermined threshold value,
Control module, for showing battery level information according to the comparative result of comparison module, be specially：If the battery
Capacity difference is less than predetermined threshold value, then alarms and show that battery status is malfunction or life-span compared with short status, otherwise shows electricity
Pond state is normal condition.
The application also provides a kind of terminal, carries out the detection of electricity by battery capacity detection module respectively, records and count
Calculate that battery capacity is poor, the state of battery is detected according to battery capacity difference, display battery status.
Further, the battery capacity when battery capacity information is fully charged per primary cell.
Further, the control module includes alarm unit and display unit, and the alarm unit is used in the electricity
