Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment shall fall within the protection scope of the present invention.
Referring to Fig. 1, the present invention provides a kind of battery performance test method, including：
Step S1, driving tester carry out line conduction test to the external test arrangements of battery modules, judge described outer
The circuit of portion's test device whether normally；
Step S2 if so, carrying out line short test to the external test arrangements, judges the external test arrangements
Circuit whether without occur short circuit；
Step S3, if so, by the external test arrangements battery modules are carried out with OCV/IR tests or function survey
Examination.
The present embodiment is by first driving tester to carry out line conduction test to the external test arrangements of battery modules, with true
The circuit normally of external test arrangements is protected, is gone out when carrying out OCV/IR tests or functional test to battery modules after avoiding
Existing empty survey is accidentally surveyed；By carrying out line short test to the external test arrangements, to ensure the line of external test arrangements
There is not the situation of short circuit in road, when carrying out OCV/IR tests or functional test to battery modules after avoiding, because outside is surveyed
Battery modules caused by the short circuit that trial assembly is put such as are caught fire or explode at the safety accidents, improve security performance during battery testing.
In one alternate embodiment, as shown in Fig. 2, the driving tester to the external test arrangements of battery modules into
Include before the step of row line continuity test：
Step S4 connects design conducting using four-wire system and connects the tester and external test arrangements, including the first inspection

P-, external test arrangements and tester form second servo loop.
In the specific implementation, the external test arrangements extend the probe for being useful for contacting with battery modules or pressure
Block, wherein, OCV/IR tests are to contact to carry out engaged test with the positive and negative lug of battery by probe, and functional test is then logical
It crosses probe and progress engaged test is contacted with the positive and negative anodes of battery protecting plate, the first detection common end P+ and the second detection are public
End S- and the connection of a probe of external test arrangements, the first test point S+ and the second test point P- and external test arrangements
Another probe connection, by tester with first detection common end P+, the first test point S+, second detect common end S- and
Second test point P- and external test arrangements form multiple circuits, so as to be filled respectively by different circuits to external testing
It puts and carries out continuity test and short-circuit test, to ensure the reliability of the internal wiring of external test arrangements, avoid that safe thing occurs
Therefore.
In one alternate embodiment, as shown in figure 3, the driving tester to the external test arrangements of battery modules into
Row line continuity test, judge the external test arrangements circuit whether normally the step of include：
Step S11, driving tester survey the described first detection common end P+ and the second detection common end S- inputs first
Trial signal；
Step S12, detects whether the first test point S+ and the second test point P- exports first test signal,
If so, then judge the circuit normally of the external test arrangements.
When implementing, the first detection common end P+, the first test point S+, external test arrangements and tester composition the
Primary Ioops, when tester inputs the first test signal by the first detection common end P+ or the second detection common end S-, such as
The internal circuit normally of fruit external test arrangements, then tester can be in the first test point S+ or the second test point P- inspections
First test signal is measured, if short-circuit conditions occurs in the internal circuit of external test arrangements, tester cannot be
First test point S+ or the second test point P- detect first test signal.
Specifically, the first relay KA1 and the second relay can be increased in the internal circuit circuit of external test arrangements
KA2, the first relay KA1 are equipped with normally opened contact K1, one end of the normally opened contact K1 and the described first detection common end P
+ conducting connection, after the internal circuit that the other end of the normally opened contact K1 passes through external test arrangements with the first test point S
+ conducting connection, when carrying out continuity test, tester causes the relay coil offer voltage of the first relay KA1 normally opened
Contact K1 is closed, and the first test signal can enter the one of normally opened contact K1 by the first detection common end P+ of probe or briquetting
End is attracted after conducting by the normally opened contact K1 of the first relay KA1 and is detected from the internal circuit of external test arrangements and first
Point S+ flows out, and is observed into PLC IO cards so as to be detected.

The internal circuit connection put；Connection, the normally opened contact is connected with the second test point P- in one end of the normally opened contact K7
The other end of K7 is as test point；Connection is connected with the described second detection common end S- in one end of the normally opened contact K8, described
The other end of normally opened contact K8 is as test point；Specifically, the normally opened contact K7 and normally opened contact K8 as test point
The other end is connect with tester, may be also connected to PLC either IO cards input terminal pass through tester, PLC IO cards detect
Whether the second detection common end S- and the second test point P- has the output of the second test signal.
Tester is driven to provide voltage to the coil of the 4th relay KA4 so that normally opened contact K6, normally opened contact K7 and often
It opens contact K8 and is closed conducting, because the first detection common end P+, the first test point S+, external test arrangements and tester form first
Circuit, and the second detection common end S-, the second test point P-, external test arrangements and tester form second servo loop, work as test
When instrument is to the first test point S+ inputs the second detection signal, if in the second detection common end S- and the second test point P-
Any one there is signal to be output to tester or PLC or IO cards, then judge external test arrangements internal circuit occur it is short
Road situation forbids the test subsequently to resistance module.
