Abstract
The utility model discloses a kind of battery cell defect detecting device, comprise calibration base plate and pressing plate, described calibration base plate and pressing plate pass through gemel connection, described calibration base plate is provided with the corresponding measured hole of link position between a plurality of and cell negative terminal, described pressing plate is provided with the threaded hole corresponding with calibrating measured hole on base plate, inserts corrosion-resistant tuning probe in described threaded hole.Battery cell defect detecting device provided by the utility model is easy to operate, can improve speed, precision and the reliability of battery cell defects detection.
Description
Technical field
The utility model relates to lead-acid accumulator field, is specifically related to a kind of battery cell defect detecting device.
Background technology
In prior art, accumulator is many lattice integral type accumulator, and namely, many lattice series seal is in same internal storage battery, and acting in conjunction provides voltage for outside.Such as 12V12Ah electromobile battery, single lattice that 6 single lattice of inner employing are 2V are in series, and positive and negative two utmost points are left in outside.For the experimental cell of research, after properties test finishes, need to be to battery dissection and analysis failure cause, but first will get rid of after whether having Dan Geman, cause battery failure before dissecting.To this, by the voltage differences that each single lattice discharges latter stage, judge which single lattice fault, current detection mode is weld punching between cell negative terminal to be tested and single lattice, during punching, with an empty battery container, aim at reference again, mesuring battary both positive and negative polarity is connected to charge-discharge machine, open discharge procedures (6A is discharged to total voltage 10.5V), to be dischargedly with the probe of multimeter, test fast successively single lattice final discharging voltage while approaching final voltage.Due to electric discharge, time voltage drop is not very fast, and with multimeter, measuring one is to have little time to switch, the 2nd, data recording is a problem, the 3rd, because of prick hole sometimes the voltage that causes not in place cannot measure.
Utility model content
In order to address the above problem, the utility model provides a kind of battery cell defect detecting device, can be quick, accurately detect cell negative terminal fault.
The technical scheme that the utility model adopts is:
A kind of battery cell defect detecting device, comprise calibration base plate and pressing plate, described calibration base plate and pressing plate pass through gemel connection, described calibration base plate is provided with the corresponding measured hole of link position between a plurality of and cell negative terminal, described pressing plate is provided with the threaded hole corresponding with calibrating measured hole on base plate, inserts corrosion-resistant tuning probe in described threaded hole.
The further technical scheme of the utility model is: on described calibration base plate, be also provided with the register pin fixing with battery upper surface.
The beneficial effects of the utility model are: battery cell defect detecting device provided by the utility model is easy to operate, can improve speed, precision and the reliability of battery cell defects detection.
Accompanying drawing explanation
Fig. 1 is the utility model front view;
Fig. 2 is the utility model vertical view.
Embodiment
As depicted in figs. 1 and 2, a kind of battery cell defect detecting device, comprise calibration base plate 1 and pressing plate 2, described calibration base plate 1 is connected by hinge 3 with pressing plate 2, described calibration base plate 1 is provided with the corresponding measured hole 5 of link position between a plurality of and cell negative terminal, described pressing plate 2 is provided with the threaded hole 6 corresponding with calibrating measured hole on base plate 1, the corrosion-resistant tuning probe 7 of the interior insertion of described threaded hole 6, and described calibration base plate 1 is provided with the register pin 4 fixing with battery upper surface.
During use, in experimental cell performance test, finish to carry out before shell dissection, battery cell defect detecting device is placed on mesuring battary, calibration base plate 1 contacts with battery upper surface, rotation register pin 4 makes it to fix with battery, aiming at measured hole 5 punches, by electric drill emplacement depth, make it to expose inside battery list lattice and connect lead alloy, rotate hinge 3 and cover the pressing plate 2 with corrosion-resistant tuning probe 7, now tuning probe 7 meetings be connected lead alloy by measured hole with inside battery list lattice and contact.The both positive and negative polarity of battery is connected to charge-discharge machine, total voltage connects battery plus-negative plate, a collection minute line ball is connected on the corresponding tuning probe 7 of each single lattice both positive and negative polarity, start discharge procedures, the voltage that now each single lattice discharges latter stage can transmit computer by charge-discharge machine and directly show numerical value, can from the difference of numerical value, judge which single lattice fault intuitively, easy to operate, can improve precision and the reliability of accumulator fast detecting.
Claims (2)
