Temperature Cycling Experiment for Battery
The temperature cycle experiment contains 27 cycles. And each cycle consists of the following steps:
01) The battery is changed from normal temperature to 66±3℃, placed for 1 hour under the condition of 15±5%.
02) Switch to a temperature of 33±3°C and a humidity of 90±5°C for 1 hour.
03) The condition is changed to -40±3℃ and placed for 1 hour.
04) Put the battery at 25℃ for 0.5 hours.
These 4 steps is a cycle. After 27 cycles of experiments, the battery should have no leakage, alkali climbing, rust or other abnormal conditions.
