For art personnel, the concrete meaning of above-mentioned term in the present invention can be understood with concrete condition.
Since battery pack includes multiple battery cores, after battery pack combo is good, often there is the excessive situation of battery core pressure difference,
So by more stringent a series of manufacturing process, quality control, for example, material is matched in single battery core production process
Side, the improvement of technique, battery core chemical conversion conformity classification, formation device verification and environment temperature control etc., in battery core assembling
In the process, it carries out more stringent screening pairing again to the voltage of battery core, internal resistance, no matter has been carried out in production or assembling
Stringent control, strict control production technology guarantee the consistency of the voltage of factory battery core, some producers are after guaranteeing assembling
Battery core voltage consistency, before battery assembly, to battery core carry out combo optimization, in general, before assembling first to be assembled
Battery core carry out voltage tester, and carry out pressure difference test, be more than pre- by the difference of voltage and average voltage if pressure difference is excessive
If the battery core of value is replaced.
However, it has been found that even if by strict control production or packaging technology and carrying out stringent screening experiment, even
Battery core is replaced before assembling, after assembling, in load-carrying situation, the dynamic differential pressure qualification rate of battery core is promoted battery pack
It is not obvious, still remains the underproof phenomenon of dynamic differential pressure of the battery core of about 10%-20%.Applicant is by a large amount of test
With analysis, the pressure difference after finding battery core assembling may be from the pressure drop that the route of each battery core is connected in solar panel, even if in group
The voltage of test battery core is consistent before dress, after assembling, in fact it could happen that the larger problem of dynamic differential pressure, to solve battery dynamic differential pressure
Big problem promotes the service life of battery pack.The utility model embodiment provides a kind of battery assembly equipment, and the equipment is for excellent
The pressure difference of battery core in electrochemical cell group, as shown in Figure 1, the equipment includes:
First test device 10, including calibrating terminal 11, calibrating terminal 11 is attached for the battery core good with combo, right
The good battery core of combo carries out dynamic differential pressure test.In the particular embodiment, carrying out combo to battery core is simulation actual assembled feelings
Condition needs for battery core to be assembled to be electrically connected with battery protecting plate B respectively according to group reload request, and the battery core after connecting can
Directly to carry out welding assembly, before welding, needs the battery core good to combo to carry out band and carry dynamic differential pressure test, specifically,
The good battery core of combo and battery protecting plate B can be mounted in fixed production fixture A, the state of the good battery core of combo is as schemed
Shown in 2.The calibrating terminal of first test device 10 is connected to corresponding position on battery protecting plate B, it is in the present embodiment, right
Battery core carries out dynamic differential pressure test, the actual conditions of the battery pack after can simulating assembling.Therefore, clearer can reflect
Battery core is in working condition in actual work.
First combo device 20 is connect with the first test device 10, for receiving the test result of the first test device 10,
When measured dynamic differential pressure is greater than or equal to preset threshold, battery core is subjected to combo again；Specifically, the first combo device
It is provided with comparator in 20, upon receipt of the test results, is carried out the dynamic differential pressure measured and preset threshold by comparator
Compare, judges whether the dynamic differential pressure measured is greater than preset threshold.In the present embodiment, alleged preset threshold is the dynamic of battery core
Pressure difference whether He Ge standard, the demand of each battery assembly producer and battery user is different, specifically, preset threshold can
Think 5mv-25mv.When measured dynamic differential pressure is greater than or equal to preset threshold, the first combo device 20 carries out battery core
Again combo.In the present embodiment, when dynamic differential pressure is unqualified, putting in order for battery core can be exchanged, specifically,
Battery core can be exchanged at random, can also be exchanged according to preset rules, such as adjacent battery core can be adjusted
It changes, is exchanged specifically, choosing the adjacent battery core of any two, it can also be according to putting in order, once to adjacent two
Battery core is exchanged, as shown in Fig. 2, 1# and 2# can be exchanged, 2# and 3# can also be exchanged.The above are explanations
Reversed order is illustratively illustrated that the exchange mode of other adjacent battery cores is applied equally to the present embodiment.In this implementation
In example, the battery core at interval can also be exchanged, be carried out pair for example, choosing and being spaced apart from each other two battery cores of at least one battery core
It adjusts, as shown in Fig. 2, 1# and 3# can be exchanged, 1# and 4# can also be exchanged, 2# and 4# can also be adjusted
It changes.The above are illustrating that reversed order is illustratively illustrated, the exchange mode at other intervals is applied equally to the present embodiment.
It, can be by Wiring device 30 by the battery core weight of the first test device 10 and combo again after the completion of combo again
New line, specific Wiring device can be manipulator, can pick up the connecting terminal 11 of the first test device and by terminals
Son 11 is placed in the corresponding position of battery protecting plate B.After the completion of line, the first test device 10 is retested, if
Dynamic differential pressure is unqualified, and the first combo device carries out combo again to battery core, until the dynamic pressure that the first test device is tested
It is poor qualified.
First welder 40 welds the battery core for the current combo that dynamic differential pressure is less than preset threshold.Specific real
It applies in example, welder 40 can be laser soldering device.
The band that the battery core good to combo carries out practical working situation carries dynamic differential pressure test, is greater than in the dynamic differential pressure measured
Or when being equal to preset threshold, battery core is arranged again, and continue dynamic differential pressure test, until dynamic differential pressure is less than default threshold
When value, it is assembled, by a large amount of time delay of applicant and analysis, there are dynamic differential pressures for battery core, are not only due to battery core sheet
The voltage of body causes, and may be influenced due to external environment, for example, voltage protection plate, the position that battery core is placed is different, after assembling
Dynamic differential pressure it is different, therefore, can before assembling it can be found that dynamic differential pressure it is undesirable be really reason, rationally arranged by battery core
Cloth reduces the dynamic differential pressure of battery core, can substantially reduce the fraction defective of battery pack, saves production cost, and improve battery pack
Service life.Applicant is selected 1000 battery packs, is divided into two groups and compares experiment, in control group by many experiments
Dynamic differential pressure be more than 25mV standard be 150, using 18mV as preset threshold in experimental group, by the group of the present embodiment
The battery pack of the standby assembly of installing, dynamic differential pressure is more than that 25mV standard is 5.It can clearly be obtained by comparative experiments, this
The battery assembly equipment of embodiment substantially reduces the fraction defective of battery pack, saves production cost, and improves the use longevity of battery pack
Life.
To realize automatic assembling, in optionally embodiment, as shown in Figure 3, further includes: transmitting device 50, being used for will
