[2] large current density electric test
When using high current charge-discharge experimental rig X2 to be tested, change successively by test body M1~M4, one by one To being tested by test body.If for an off-test by test body, changed by test body, into next quilt The experiment of test body.Experiment is implemented by test body M1~M4 successively to four by this way.
As shown in Fig. 8 (b), high current charge-discharge experimental rig X2 possesses one and low current charge/discharge testing device X1 Discharge and recharge electric source for test purposes E1~E4 compared to the larger discharge and recharge electric source for test purposes E0 of capacity.As illustrated, will be from low current Four that charge/discharge testing device X1 setting place transfer comes are connected by first among test body M1~M4 by test body M1 It is connected to the discharge and recharge electric source for test purposes E0 of Large Copacity.Remaining three turn into holding state by test body M2~M4.According to control The control in portion 10, experiment is implemented using the discharge and recharge electric source for test purposes E0 of Large Copacity firstly for first by test body M1.
For first by test body M1, after high current charge-discharge off-test, by this by test body M1 from great Rong Separated in the discharge and recharge electric source for test purposes E0 of amount connection status, filling for Large Copacity is instead of connected to by test body M2 by second Discharge test power supply E0, examination is implemented using the discharge and recharge electric source for test purposes E0 of Large Copacity for this second by test body M2 Test.
For second by test body M2, after high current charge-discharge off-test, by this by test body M2 from great Rong Separated in the discharge and recharge electric source for test purposes E0 of amount connection status, filling for Large Copacity is instead of connected to by test body M3 by the 3rd Discharge test implements experiment with power supply E0.
For the 3rd by test body M3, after high current charge-discharge off-test, by this by test body M3 from Large Copacity Discharge and recharge electric source for test purposes E0 separation, the discharge and recharge electric source for test purposes that Large Copacity is instead of connected to by test body M4 by the 4th E0 come implement experiment.For the 4th by test body M4, after high current charge-discharge off-test, by this by test body M4 from big The discharge and recharge electric source for test purposes E0 separation of capacity.

Patent document 1:Japanese Patent Laid-Open 2003-282150 publications
It is above-mentioned in the prior art, implement in switching for being filled by the low current charge and discharge electric test of test body with high current On the basis of discharge test, low current charge and discharge electric test needs its special low current charge/discharge testing device, large current density Electric test needs its special high current charge-discharge experimental rig.Therefore there is testing equipment as entirety turns into large scale equipment Problem.Further, since the connection replacing and place movement by test body are carried out by manually, therefore operating efficiency significantly drops It is low.
Fig. 9 shows that the existing of low current charge/discharge testing device X1 and high current charge-discharge experimental rig X2 is being applied in combination Action form in technology.Time shaft t is taken in the right oblique direction of paper, in the upward obtaining current axle i of paper vertical direction.Separately Outside, in fig .9, following situation is shown respectively:
Four are respectively trystate by test body M1~M4;
Low current charge/discharge testing device X1 and high current charge-discharge experimental rig X2 is independent individual;
For four each rectangular-shaped waveforms by test body M1~M4, it is highly small for low current discharge and recharge examination Test, its height it is big for large current density electric test;
Long test period is long on time-axis direction, and short test period is short on time-axis direction.From as described above Can clearly go out in the Fig. 9 showed like that, in low current charge and discharge electric test, due to implement life test thus test period become It is long.In addition, in large current density electric test, due to implement attribute testing thus test period shorten.
Below, the content of the test to Fig. 9 is specifically described.First, at the trial between in section t11, filled using low current Discharge test device X1 implements low current charge and discharge electric test simultaneously in parallel to four by test body M1~M4.Four by test body M1~M4 waveform is depicted in the experiment that parallel practice simultaneously is meant to be in same time range.
Then transfer time section t12 in, by four by test body M1~M4 from low current charge/discharge testing device X1's The discharge and recharge electric source for test purposes E1 of low capacity~E4 dismountings, four of dismounting are tried by test body M1~M4 from low current discharge and recharge Experiment device X1 setting place is transported to high current charge-discharge experimental rig X2 setting place, enters to be about to subject and tests body M1~M4 Among first by test body M1 connections change to high current charge-discharge experimental rig X2 Large Copacity charge and discharge electric test use Power supply E0 operation.
Between at the trial in section t13, it is implemented separately successively for four quilts using high current charge-discharge experimental rig X2 Test body M1~M4 large current density electric test.Four are depicted in mutually different time range by test body M1~M4 It is meant to be the experiment individually implemented successively.For being connected after first high current charge-discharge off-test by test body M1 It is tm to change to second time needed for test body M2.The connection replacing construction tm for second by test body M2's After high current charge-discharge off-test connection change to the 3rd by during test body M3 and also for the 3rd by test body After M3 high current charge-discharge off-test connection change to the 4th by test body M4 when be also required to.Therefore, test period Section t13 is connected replacing for the total ascent time of four single high current charge-discharge test periods by test body M1~M4 with three times The summation total ascent time of both time tm time.
Repeat low current charge and discharge electric test and large current density electric test.With transfer time section t14, in the part In, enter to be about to the 4th and dismantled by test body M4 from the discharge and recharge electric source for test purposes E0 of Large Copacity, by four by test body M1~ M4 from high current charge-discharge experimental rig X2 setting place are transported to low current charge/discharge testing device X1 setting place, and All charge and discharge electric tests changed by test body M1~M4 connections to low current charge/discharge testing device X1 low capacity are used Power supply E1~E4 operation.Connection enters next circulation after the completion of changing, and repeats to implement the experiment of low current charge and discharge electric test Time period t 11, transfer time section t12, the test period section t13 of large current density electric test and transfer time section t14 this four One group of a cycle operation.
It is as follows, it can be seen from the concept map of the Fig. 9,
Using one group of low current charge/discharge testing device X1 and both high current charge-discharge experimental rig X2, not only exist As very big burden in terms of equipment cost, and initial cost and operating cost also tend to uprise.In addition, in space leeway Upper burden is also very big.
Make the homework burden for being moved to different tests device by test body M1~M4 also very big.Although repeating same work Industry, but high current should will be transported to by test body M1~M4 from low current charge/discharge testing device X1 setting place every time Charge/discharge testing device X2 setting place, in addition on the contrary, being transported from high current charge-discharge experimental rig X2 setting place To low current charge/discharge testing device X1 setting place, the very big amount of labour is resulted in the need for.
Due to not only transporting by test body M1~M4, it is necessary to repeat to be changed by test body M1~M4 connection and make Industry, therefore burden further increasing.Frequently increase and the failure for the maintenance load for bringing charge/discharge testing device are changed in connection The increase of rate.
Maximum the problem of is this following point.That is, in low current charge/discharge testing device X1 operation, high current charge-discharge Experimental rig X2 is changed into holding state (off-duty state), on the contrary, in high current charge-discharge experimental rig X2 operation, small electricity Stream charge/discharge testing device X1 is changed into holding state this point.In fig .9, P1, P2 show that experimental rig X1, X2 are holding state Period.For high current charge-discharge experimental rig X2, the test period section of low current charge/discharge testing device X1 operations T11 All Time is changed into holding state.In addition, for low current charge/discharge testing device X1, high current charge-discharge examination The test period section t13 of experiment device X2 operations All Time is changed into holding state.The electric current of above-mentioned low current high current fills Discharge test device X1, X2 both sides, which are alternately repeated running status and holding state, can make the overall operational efficiency of equipment considerably It is low.
In addition, in view of carrying out four of left side top half for Fig. 9 by test body M1~M4 with the time difference Large current density electric test when the loss of time, filled to carry out high current by test body M1~M4 to four simultaneously in parallel , also there is the scheme for preparing four (in general many) high current charge-discharge experimental rig X2 in discharge test.But, due to big Current charge-discharge electric test device X2 is even one also very large-scale, so if preparing four (in general many), then result To cause significantly rising violently for installation cost.
It is used as the solution of the next step for above-mentioned prior art problem, it may be considered that countermeasure as follows. In the countermeasure, make large-scale experiment device Y that there is high current charge-discharge test model and two kinds of moulds of low current discharge and recharge test model Formula, by switching tests pattern, makes to be alternately repeated following action successively by test body, i.e. for one by test body successively entered Row low current charge and discharge electric test and large current density electric test.That is, using four by test body M1~M4 as object when, will be large-scale Experimental rig Y is set as on the basis of low current discharge and recharge test model implementing low current discharge and recharge by test body M1 to first Experiment, after it terminates, high current charge-discharge test model is switched to by large-scale experiment device Y, identical is tested for first Body M1 implements large current density electric test.
Then, to second on the basis of large-scale experiment device Y to be switched to low current discharge and recharge test model again Low current charge and discharge electric test is implemented by test body M2, after it terminates, large-scale experiment device Y is switched into large current density electric test Pattern, large current density electric test is implemented to identical second by test body M2.
And then, switch to low current discharge and recharge test model to implement low current charge and discharge by test body M3 to the 3rd again Electric test, after it terminates, switches to high current charge-discharge test model to implement large current density by test body M3 to identical Electric test.Finally, low current discharge and recharge test model is switched to implement low current discharge and recharge examination by test body M4 to the 4th Test, after it terminates, switch to high current charge-discharge test model to implement high current charge-discharge examination by test body M4 to identical Test.
Figure 10 shows the action form in the large-scale experiment device Y involved by this countermeasure.
First, the discharge and recharge electric source for test purposes for the Large Copacity for large-scale experiment device Y being connected to by test body M1 by first E0, implements low current charge and discharge electric test under low current discharge and recharge test model, then switches to large current density electric test mould Formula implements large current density electric test.
Then, second is used by the test body M2 charge and discharge electric tests for being connected to Large Copacity by test body M1 instead of first Power supply E0, implements low current charge and discharge electric test under low current discharge and recharge test model, then switches to high current charge-discharge to try Pattern is tested to implement large current density electric test.
Then, the 3rd is used by the test body M3 charge and discharge electric tests for being connected to Large Copacity by test body M2 instead of second Power supply E0, implements low current charge and discharge electric test under low current discharge and recharge test model, then switches to high current charge-discharge to try Pattern is tested to implement large current density electric test.
Finally, the 4th is used by the test body M4 charge and discharge electric tests for being connected to Large Copacity by test body M3 instead of the 3rd Power supply E0, implements low current charge and discharge electric test under low current discharge and recharge test model, then switches to high current charge-discharge to try Pattern is tested to implement large current density electric test.
And then, in order to carry out the experiment of second circulation, instead of the 4th by test body M4 connections first by test body M1, and repeat above-mentioned identical processing.
It is as follows, it can be seen from the concept map,
In the schemes of countermeasures, every time to be connected to Large Copacity discharge and recharge electric source for test purposes E0 by test body carry out more , it is necessary to connect replacing construction tm when changing.
The discharge and recharge electric source for test purposes E0 of Large Copacity implements the time period t s of low current charge and discharge electric test with implementing high current The time period t b of charge and discharge electric test, which is compared, significantly to be extended.If enumerating an example of time span, large current density electric test Time period t b is several minutes, on the other hand, low current discharge and recharge test period section ts digit significant difference, is the length of 5~6 days Degree.The discharge and recharge electric source for test purposes E0 of Large Copacity is according to from the point of view of literal, and its abilityscale is big, is grown because of low current charge and discharge electric test Time occupies ability big like that, can produce as the extremely low new problem of overall operational efficiency.
On the other hand, it is also contemplated that in the following manner, it is not the discharge and recharge electric source for test purposes E0 of Large Copacity, but such as Figure 11 It is shown, discharge and recharge electric source for test purposes E1~E4 of four low capacities is connected to one by test body in the lump, successively to being tested Body M1~M4 carries out large current density electric test.In this case, four for example are connected in parallel by test body M1 to first Discharge and recharge electric source for test purposes E1~E4 of low capacity, remaining three are holding state by test body M2~M4.
All it is being connected to discharge and recharge electric source for test purposes E1~E4 for first four low capacity by test body M1 In the state of high current charge-discharge off-test after, then instead of by test body M1 connections second by test body M2, with same The mode of sample carries out large current density electric test.3rd by test body M3, the 4th by test body M4 similarly.
But, just because of being repeated to be connected to four by test body by one respectively by test body M1~M4 for four Discharge and recharge electric source for test purposes E1~E4 of low capacity job dependence is in manual work, so the very big amount of labour can be forced, and It is difficult to as actual solution.
In addition, continually carrying out being changed by the connection of test body and mobile by manual work, test accuracy can be caused Deterioration, so that causing the reliability of result of the test reduces.
