UN 38.3/IEC 62133 Lithium-ion Battery Test Chamber

As a lithium-ion battery test chamber manufacturer, KOMEG has extensive experience in the field of secondary cells/batteries testing, and many customers have recognized the quality of our products. Here we mainly introduce UN 38.3 and IEC 62133, the two lithium-ion battery test standards that our customers consult most about.

UN 38.3 Secondary Cells and Batteries Test

UN 38.3

Altitude Simulation (Primary and Secondary Cells and Batteries)
Thermal Test (Primary and Secondary Cells and Batteries)
Vibration (Primary and Secondary Cells and Batteries)
Shock (Primary and Secondary Cells and Batteries)
External Short Circuit (Primary and Secondary Cells and Batteries)
Impact (Primary and Secondary Cells)
Overcharge (Secondary Batteries)
Forced Discharge (Primary and Secondary Cells)

Altitude Simulation:

Stored for more than 6 hours under pressure ≤11.6kPa and ambient temperature (20±5℃).

Thermal Test:

Store at 75±2℃ for at least 6 hours (large cells/batteries need to be stored for 12 hours), and then store at -40±2℃ for the same time. The transition time between the two extreme temperatures must be within 30 minutes. Repeat the test for 10 cycles. Finally store at 20±2℃ for 24 hours.

Requirements: no mass loss, leaking, venting, disassembly, rupture or fire. And the open circuit voltage after the test is not less than 90% of that before the test (Note: The voltage requirement does not apply to cells/batteries in a fully discharged state)

Temperature cycling
Incorrect installation (Cells)
External short circuit
Free fall
Mechanical shock (Crash hazard)
Thermal abuse (Cells)
Crushing of cells

External Short Circuit (Cells)
External Short Circuit (Batteries)
Free Fall
Thermal Abuse (Cells)
Crush (Cells)
Over-charging of batteries
Forced discharge (Cells)
Vibration

Forced Internal Short Circuit (Cells)

Temperature Cycling (IEC 62133-1):

Step 1: Place the cells or batteries in an ambient temperature of 75±2℃ for 4 hours.

Step 2: Reduce the temperature to 20±5℃ within 30 minutes and test for 2 hours

Step 3: Reduce the temperature to -20±2℃ within 30 minutes and test for 4 hours

Step 4: Raise the temperature to 20±5℃ within 30 minutes and test for 2 hours

Step 5: Repeat steps 1 to 4 for a further four cycles. Transition from step 4 to step 1 within 30 min.

Thermal Abuse (IEC 62133-1/IEC 62133-2):

The oven temperature is raised at a rate of 5℃/min±2℃/min to a temperature of 130±2℃. The cell remains at this temperature for 30 min. Requirements：No fire, no explosion.

Low Pressure (IEC 62133-1):

Each fully charged cell is placed in a vacuum drying chamber, in an ambient temperature of 20±5℃. Once the chamber has been sealed, its internal pressure is gradually reduced to a pressure equal to or less than 11.6kPa and held for 6 hours. Requirements：No fire, no explosion, no leakage.
