Description
Technical field
The invention belongs to battery detecting technical field, and in particular to a kind of inspection party for li-Mn button cell monomer
Method.
Background technology
Li-Mn button cell refers to material for lithium-manganese dioxide, and appearance and size is as the battery of a little button.Server master board
The upper conventional CR series not charged, model CR2032, its name is according to IEC (International
Electrotechnical Commission International Electrotechnical Commissions) standard name, wherein C- with lithium metal as negative pole, with
Chemical cell system of the manganese dioxide for positive pole, R- represent the cylindrically shaped of battery, and 20 represent that the diameter of battery is 20mm,
32 height for representing battery are 3.2mm, and nominal voltage is 3.0V, and final voltage (End Point Voltage) is 2.0V, specified
Capacity is 200-230mAh.
Its appearance is stainless steel material, and used as positive pole, its negative pole is stainless circular lid, has between positive pole and negative pole
Sealing ring insulate, and sealing ring is made with nylon, and sealing ring is in addition to insulating effect is played, moreover it is possible to prevent electrolyte from leaking.
A li-Mn button cell can be all installed on server master board at present（Model C R2032）, so as in server power-off
In the case of to CMOS chip（Complementary Metal Oxide Semiconductor CMOSs are partly led
Body, is commonly used to preservation computer and starts substantially information, such as time, date, startup setting etc.）Power supply, so as to can guarantee that during system
(Basic Input Output System basic input output systems, in store computer is most for the accuracy of clock and BIOS settings
Important basic input/output routine, startup self-detection program, system self-triggered program, provide for computer the bottom, most straight
The hardware setting for connecing and control, it can read from CMOS system setting specifying information) correctness.
When the battery electric quantity is not enough or does not have electricity, it is possible that cannot arrange startup password, cannot preserve BIOS arrange,
It is abnormal that the boot system time is abnormal, start does not show, normally cannot start, system is restarted automatically etc., has a strong impact on user's
Normal use.
The detection of electricity is not carried out to battery in prior art before battery is installed to server, when battery cell electricity
Cause when amount is not enough server cannot normal work, in place of this is the deficiencies in the prior art.
Content of the invention
It is an object of the invention to, for the defect that above-mentioned prior art is present, there is provided design is a kind of to be directed to lithium manganese button
The method of inspection of battery cell, to solve above-mentioned technical problem.
For achieving the above object, the present invention provides technical scheme below：
A kind of method of inspection for li-Mn button cell monomer, it is characterised in that comprise the following steps：
Step 1）：Li-Mn button cell to be measured is placed in 0 DEG C ~ 30 DEG C environment so that li-Mn button cell own temperature to be measured
Between 0 DEG C ~ 30 DEG C；
Step 2）：Li-Mn button cell to be measured is placed in the environment that relative humidity is 40% ~ 75% so that lithium manganese button electricity to be measured
The relative humidity in pond itself is 40% ~ 75%；
Step 3）：The voltage of li-Mn button cell to be measured is measured, if li-Mn button cell voltage to be measured is more than or equal to
2.9V, judges that li-Mn button cell to be measured is qualified, otherwise regards as unqualified.
Preferably, described step 1）In so that li-Mn button cell own temperature to be measured is 21 DEG C.
Preferably, described step 2）In so that the relative humidity of li-Mn button cell to be measured is 50%.
Preferably, in described step 3, using the voltage of universal meter measurement li-Mn button cell to be measured.
The beneficial effects of the present invention is, it is contemplated that improve test coverage, by test battery cell it
Before so as in suitable temperature and relative humidity, to guarantee battery performance stability.By increasing to battery cell voltage
Measure, the battery for not meeting design requirement is rejected in time, it is ensured that product normally runs, it is to avoid cause bad stream because testing careless omission
Enter market and cause customer complaint, reduce customer service operation cost, improve customer satisfaction.Additionally, design principle reliability of the present invention, structure letter
Single, with application prospect widely.
As can be seen here, the present invention compared with prior art, improves with prominent substantive distinguishing features and significantly, and which is implemented
Beneficial effect be also obvious.
Description of the drawings
Fig. 1, li-Mn button cell CR2032 storage temperature and time and electricity keep linear relationship chart.
Fig. 2, li-Mn button cell CR2032 voltages and electricity performance diagram.
Fig. 3, li-Mn button cell monomer voltage measure schematic diagram.
Specific embodiment
The present invention will be described in detail below in conjunction with the accompanying drawings and by specific embodiment, and following examples are to the present invention
Explanation, and the invention is not limited in implementation below.
As shown in figure 1, according to the corresponding relation of CR2032 battery storage temperature and times, storing up in warehouse after battery supplied materials
When depositing, at 0 DEG C ~ 30 DEG C, relative humidity RH (Relative Humidity) is controlled 40% ~ 75% its temperature control, and 21 DEG C for most
