The test method first embodiment of battery core short-circuit test device:
The test method for present embodiments providing a kind of battery core short-circuit test device, it uses above-mentioned battery core short-circuit tests
The battery core short-circuit test device of Installation practice carries out short-circuit test to battery core, below in conjunction with Fig. 4 to battery core short-circuit test device
Test method be illustrated.
Step is first carried out when carrying out short-circuit test to battery core in the test method of the present embodiment battery core short-circuit test device
Battery core is moved at test bar unit by S11, feeding line.Controller 3 controls feeding line 4 and is transmitted, so that motor 42 drives
Transmission belt drives fixture 43 to be thereon moved at test bar unit 1, so that on the first reference test bar group 11 and the fixture 43
The positive pole ear of battery core contacted, the second reference test bar group 12 is contacted with the negative lug of the battery core on the fixture 43,
In order to which short-circuit tester 2 can carry out short-circuit test to battery core by test bar unit 1.
Before battery core formally carries out short-circuit test, step S12 is executed, short-circuit tester is to the first reference test bar group and battery core
The contact situation of first tab is detected, and sends the first detection data to controller.Specifically, it is formally carried out in battery core short
Lu Qian, controller 3 first can send first control signal to short-circuit tester 2, so that short-circuit tester 2 is obtaining first control
After signal, the first connecting terminal 211 and the second connecting terminal 221 are connected by detection circuit, at this point, short-circuit tester 2 is first right
First reference test bar group 11 is detected with the contact situation of the positive pole ear of battery core, i.e., short-circuit tester 2 can be to the first terminals
Son 211 sends the first detection voltage, and obtains the first feedback voltage, then, short-circuit tester 2 by the second connecting terminal 221
The first detection data can be sent to controller 3 according to the first feedback voltage of acquisition.
Controller 3 executes step S13, judges between the first reference test bar, the second reference test bar after obtaining the first detection data
It whether is open circuit.When the voltage value that short-circuit tester 2 obtains is zero, then show the first reference test bar 111 and the second reference test bar 112
At least one of with the positive pole ear poor contact of battery core or do not contacted namely the first reference test bar group 11 is located at battery core
Positive pole ear is effectively contacted, and is open circuit between the first reference test bar 111 and the second reference test bar 112.At this point, step S15 is executed,
When battery core is moved to culling unit, culling unit removes battery from fixture.
When short-circuit tester 2 obtains certain voltage value, then show the first reference test bar 111 and the second reference test bar 112
It contacts normal namely the first reference test bar group 11 with the positive pole ear of battery core to contact with the positive pole ear of battery core normally, the first test
It is access between bar 111 and the second reference test bar 112, short-circuit test can be carried out to battery core.At this point, step S14 is executed, short circuit inspection
It surveys instrument and short-circuit detecting is carried out to battery core, and send the second detection data to controller.Short-circuit tester 2 carries out short-circuit inspection to battery core
Measuring tool body includes: that controller 3 first sends second control signal to short-circuit tester 2 so that short-circuit tester 2 obtain this second
After controlling signal, the first connecting terminal 211 and third connecting terminal 222 are connected by detection circuit.Then, short-circuit tester 2
The second detection voltage is sent to the first connecting terminal 211, and the second feedback voltage is obtained by third connecting terminal 222.Then,
Short-circuit tester 2 can send the second detection data to controller 3 according to the second feedback voltage of acquisition.
Controller 3 executes step S16 after obtaining the second detection data, judges that battery core has short circuit.Work as short-circuit tester
When 2 voltage values obtained are in given threshold, then showing battery core, there is no short circuit problems.When the voltage that short-circuit tester 2 obtains
When value sends the voltage value of the second detection voltage to the first connecting terminal 211 equal or close to short-circuit tester 2, then show battery core
There are short circuit problems, execute step S17 at this time, when battery core is moved to culling unit, culling unit moves up battery core from fixture
It removes.
