Abstract
The invention provides a mobile phone battery detection method. The method comprises the steps that (A), a battery cell artificial load test is carried out, wherein battery cells are connected into an artificial load, electrical parameter output of the battery cells is tested, and following steps are executed on the battery cores with the electrical parameters conforming to preset values; (B), a semi-finished product performance test is carried out; (C), a finished product performance test is carried out. In this way, a simple battery core voltage test is changed into the battery core artificial load test, the electric quantity of the battery cores is tested by connecting the battery cores into the artificial load, and therefore the problem that defective products with insufficient battery core electric quantity cannot be screened out due to the fact that only voltages of battery cores are detected in traditional detection is avoided.

Summary of the invention
Technical matters to be solved by this invention is: the battery of mobile phone dispatching from the factory is detected whether its energy is up to standard in testing process, thereby avoid the outflow without battery.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of battery of mobile phone detection method, comprise step,
A) battery fictitious load test, accesses fictitious load the output of test battery core electrical quantity by battery, and the battery that electrical quantity is met to preset value continues step;
B) semi-manufacture performance test;
C) end properties test.
Beneficial effect of the present invention is: by simple battery voltage tester being replaced by the test of battery fictitious load, battery is accessed and in fictitious load, tests its electric weight situation, thereby avoided only detecting battery voltage in traditional detection and the problem that cannot filter out the defective products of battery electric weight deficiency.
Brief description of the drawings
Below in conjunction with accompanying drawing in detail concrete structure of the present invention is described in detail
Fig. 1 is battery of mobile phone detection method process flow diagram in prior art;
Fig. 2 is battery of mobile phone detection method process flow diagram of the present invention;
Fig. 3 is fictitious load test particular flow sheet of the present invention.
Embodiment
By describing technology contents of the present invention, structural attitude in detail, being realized object and effect, below in conjunction with embodiment and coordinate accompanying drawing to be explained in detail.
The design of most critical of the present invention is: by battery is accessed to fictitious load, further test its electric weight situation, thereby avoid only detecting battery voltage in traditional detection and cannot filter out the problem of the defective products of battery electric weight deficiency.
Refer to Fig. 2, the invention provides a kind of battery of mobile phone detection method, comprise step,
A) battery fictitious load test, accesses fictitious load the output of test battery core electrical quantity by battery, and the battery that electrical quantity is met to preset value continues step;
B) semi-manufacture performance test;
C) end properties test.
From foregoing description, beneficial effect of the present invention is: the battery voltage tester in traditional detection is improved to battery fictitious load test of the present invention, by being accessed, battery in fictitious load, tests its electric weight situation, electric weight situation to battery is differentiated screening, thereby has avoided only detecting battery voltage in traditional detection and the problem that cannot filter out the defective products of battery electric weight deficiency.
Embodiment 1:
Referring to Fig. 3, described steps A specifically comprises step,
A1) choose mesuring battary core;
A2) detect mesuring battary core voltage, judge whether it meets setting range, is to continue step, get rid of otherwise set it as defective products;
A3) load testing circuit calibration;
A4) by mesuring battary core access load testing circuit, detecting its electrical quantity and whether meet preset value, is to perform step B, gets rid of otherwise set it as defective products; Described electrical quantity comprises voltage and/or electric current.
In the present embodiment, before fictitious load detection, first the voltage of battery is detected battery is carried out, get rid of the defective products battery of undertension, the battery of voltage conforms setting range is further carried out to load testing.And test is determined according to the electrical quantity (as voltage, electric current etc.) that detects access load circuit, tests effectively simple.
Embodiment 2:
Further, above-mentioned steps A1 is for choosing at random multiple mesuring battary cores.
That is, this method of testing is not only applicable to the full inspection to sample, and in order to raise the efficiency, the method can realize being suitable for of sampling observation in to a large amount of samples.
Embodiment 3:
Further, described steps A 3 is:
By one of them mesuring battary core access load testing circuit of choosing, the circuit load of adjustment load testing detects the electric current of mesuring battary core simultaneously, when electric current reaches after scheduled current, and completing circuit calibration.
Described steps A 4 is:
All the other mesuring battaries newly being accessed to load testing circuit, detect its voltage and whether be greater than predeterminated voltage, is to perform step B, gets rid of otherwise set it as defective products; Described electrical quantity comprises voltage and/or electric current.
The present embodiment proposes with one of them calibration reference as load testing circuit of multiple mesuring battary cores of choosing, and the largest benefit of so doing is to avoid to greatest extent to cause the inaccurate problem of load testing circuit test because of the battery difference of different batches.
Embodiment 4:
In described steps A 2, setting range is 3.90V～3.95V.
The present embodiment has provided an interpretable voltage range, and this voltage range draws via applicant's great many of experiments, is a best voltage range value.But it should be noted that, because each producer voltage regulation is different, therefore this voltage range is mainly applicable to the detection of the battery of mobile phone.
Embodiment 5:
In described steps A 3, predetermined current is 0.5C5A; In described steps A 4, predeterminated voltage is 3.85V.
The present embodiment has provided an interpretable predetermined current and predeterminated voltage, and this predetermined current and predeterminated voltage are to draw via applicant's great many of experiments equally, is a best predetermined current and predeterminated voltage value.But it should be noted that, due to each producer battery specification difference, therefore this predetermined current and predeterminated voltage are mainly applicable to the detection of the battery of mobile phone.
In sum, the battery voltage tester in traditional detection is improved to battery fictitious load test of the present invention by scheme provided by the invention, further in the test of battery fictitious load, first the voltage of battery is detected, thereby get rid of the defective products battery of undertension, select again the battery of same batch to calibrate load testing circuit, thereby guarantee test accuracy, finally the battery of other voltage conforms setting ranges is further carried out to load testing, according to detecting the electrical quantity that accesses load circuit (as voltage, electric current etc.) determine electric weight situation, test is effectively simple, can be to undertension in battery, the defective products of electric weight deficiency is differentiated screening, thereby the problem of having avoided only detecting battery voltage in traditional detection and cannot filter out the defective products of battery electric weight deficiency.
