Simulation of high altitude low pressure testing machine
Test Purpose
Battery Simulation High Altitude and Low Voltage Testing Machine
The objective of this test is to ensure that the battery does not explode or catch fire. Furthermore, it should not emit smoke or leak, and the battery protection valve should remain intact. The test also evaluates the performance of other electronic and electrical products under low voltage conditions, ensuring that they function properly and are not damaged.
Standard Requirements
Simulated high-altitude low-pressure test chamber
Following the specified test method, the battery is fully charged and then placed in a vacuum box at a temperature of 20°C ± 5°C. The pressure inside the box is reduced to 11.6 kPa (simulating an altitude of 15240 m) and maintained for 6 hours. During this time, the battery must not catch fire or explode. Additionally, it should not exhibit any signs of leakage.
Note: The ambient temperature of 20°C ± 5°C is regulated to meet the standard requirements.
