IEC 62133 UN38.3 80mΩ ± 20mΩ Cell Battery External Short Circuit Tester

IEC 62133 UN38.3 Current 1000 A External Short Circuit 55 ± 5 ℃ Battery Testing Equipment

Product Name:Battery short-circuit testing machine

Product Model:GX-6055

Test purpose: This test simulates an external short circuit

Cell Test Procedure: Fully charge each cell according to the second procedure in 7.1.2 store in an ambient temperature of 55 ± 5 ℃, after stabilization for 1hour to 4 hours and while still in an ambient temperature of 55 ± 5 ℃, the cell is short circuited by connecting the positive and negatitive terminals with a total external resistance of 80mΩ±20mΩ, the cell remains on test for 24hours or until the surface temperature declines by 20% of the maximum temperature rise, whichever is the sooner.

Battery Test Procedure: A fully charged battery according to the procedure in 7.1.1 is stored in an ambient temperature of 20 ± 5 ℃. the battery is then short circuited by connecting the posititive and negative terminals with a total external resistance of 80mΩ±20mΩ, the battery remains on test for 24 hours or until the case temperature of battery declines by 20% of the maximum temperature rise, whichever is the sooner, however, in case of a rapid decline in the short circuit current, the battery should remain on test for an additional one hour after the current reaches a low end steady state condition, this typically refers to a condition where the per cell voltage(series cells only) of the battery is below 0.8V and is decreasing by less than 0.1V and 30 min period.

Requirement: Short circuit of positive and negative terminals of the battery shall not cause fire or explosion

Test standard:

GB 18287-2013, QB/T 2502-2000, IEC 62133, UN38.3, UL 2054, UL 1642, QC/T 744-2006, QC/T 743-2006,
