How is the differences of the thermal cycling test procedures between IEC 60086-4 and IEC 62133-1?
Test Procedure as per IEC 60086-4:2014 clause 6.4.2:
Test cells and batteries shall be stored for at least 6h at a test temperature of 72 ℃, followed by storage for at least 6 h at a test temperature of -40 ℃. The maximum time for transfer to each temperature shall be 30 min. Each test cell and battery shall undergo this procedure 10 times. This is then followed by storage for at least 24 h at ambient temperature.
For large cells and batteries the duration of exposure to the test temperatures shall be at least 12 h instead of 6 h.
Test Procedure as per IEC 62133-1:2017 clause 7.2.4:
Fully charged cells or batteries are subjected to temperature cycling (-20 ℃, +75 ℃), in forced draught chambers, according to the following procedure.
Step 1: Place the cells or batteries in an ambient temperature of +75 ℃ ±2 ℃ for 4 h.
Step 2: Change the ambient temperature to 20 ℃ ±5 ℃ within 30 min and maintain at this temperature for a minimum of 2 h.
Step 3: Change the ambient temperature to -20 ℃ ±2 ℃ within 30 min and maintain at this temperature for 4 h.
Step 4: Change the ambient temperature to 20 ℃ ±5 ℃ within 30 min and maintain at this temperature for a minimum of 2 h.
Step 5: Repeat steps 1 to 4 for a further four cycles. Transition from Step 4 to Step 1 within 30 min.
Step 6: After the fifth cycle, store the cells or batteries and conduct a visual check after a rest period of at least 24 h.
