1. Equipment use:
battery low voltage (high altitude) simulation test, all tested samples are tested at 11.6kPa (1.68psi) negative pressure for high-altitude simulation test, all tested samples are tested under low pressure
2. Test purpose:
the final test result requires that the battery cannot explode or catch fire; In addition, the battery should not smoke or leak, and the battery protection valve should not be damaged Test whether other electrical and electronic products can work properly or be damaged at low voltage
3. According to the standard:
GB 31241-2014 “Safety requirements for lithium-ion batteries and battery packs for portable electronic products” UN
38.3 “Dangerous goods transport recommendations – Manual of tests and standards”,
UL 1642 ” Standard for Lithium Batteries “Part III, Section 38.3”
UL 2054 “Household and Commercial Battery Packs”
IEC62133-2012 “Accumulators and Battery Packs Containing Alkaline or Non-Acidic Electrolytes – Safety Requirements for Sealed Batteries and Batteries for Portable Devices” Standard Requirements:
After the battery is fully charged according to the prescribed test method, the battery is placed in a vacuum chamber at 20°C ± 5°C, and the chamber is emptied to reduce the pressure to 11.6kPa (simulated altitude 15240m) and held for 6 hours.
The battery should not catch fire, explode or leak.
Note: 20°C±5°C is the ambient temperature, and the ambient temperature should be controlled within the standard requirements.
