The design standard for trying equipment is very low mainly for household electrical appliances, the purely resistive load of medical industry and this kind of static capacity of digital battery
Low capacitive load lacks enough adaptability to the test request of power battery.It is tested since the high capacitive of battery will lead to
Stage beginning, the charging current of generation was excessive and exceeds the detection device leakage current upper limit since electric current is flown up, thus generate
Erroneous judgement.
Summary of the invention
The technical problem to be solved in the present invention is that: it solves existing insulation inner walkway equipment and is not suitable with high capacitive load
Problem, by the improvement of test method, erroneous judgement, misjudgement caused by reducing as detecting high capacitive load, to improve detection
Accuracy.

1, a kind of method evaded current over pulse and battery pressure resistance Insulation test is influenced, comprising the following steps:
1) battery completed laser welding but not yet carried out injecting electrolytic solution is chosen；
2) initial charge is carried out to battery in time T1 using primary voltage；
3) after the completion of initial charge, recharging is carried out to battery in time T2 using secondary voltage, and time T2 is big
In time T1；
4) the insulation internal resistance resistance value of battery is calculated according to recharging result, and according to preset insulation internal resistance criterion of acceptability
Determine whether battery insulation is up to standard.
Preferably, the static capacity of the battery is 200nF-2000nF.
Preferably, the primary voltage is 100V-500V.

Beneficial effects of the present invention are as follows:
Method of the invention, step is easy, and detection efficiency is high, has evaded the high capacitive bring test starting due to battery
The false alarm that stage generates since charging current that electric current flies up generation is excessive beyond the equipment leakage stream upper limit, keeps away
The erroneous judgement of insulation internal resistance is exempted from, under the premise of not changing existing equipment and not increasing production cost, test accuracy is obtained
It significantly improves.
