Technical parameters of walk-in low-pressure laboratory and walk-in high and low temperature low-pressure laboratory
1、 The high-altitude test shall be conducted according to the following steps:
- The test object is a battery pack or system.
- Test environment: Atmospheric pressure conditions at an altitude of 4000m or equivalent, with a temperature of room temperature.
- Leave the test object in the testing environment of 7.12.2 for 5 hours and perform a constant current discharge of 1C (not exceeding 400A) until the discharge cut-off condition is reached. Observe for 2 hours.
- Requirement: The battery pack or system should have no sharp changes in discharge current, abnormal voltage, leakage, shell rupture, fire or explosion, etc. The insulation resistance value after the test shall not be less than 100 Ω/V
