Catalog excerpts

Simulated high-altitude test machine simulates the test of the battery pack or system in a constant temperature or temperature-variable low-pressure state (and high-altitude state) test, whether the discharge current will change, voltage abnormality, leakage, shell rupture, fire Or explosions and other phenomena. The battery core in the battery pack is packaged under the pressure of standard atmospheric pressure. Under normal conditions, the internal and external pressures are basically balanced. When the battery pack is used on the plateau, the atmospheric pressure is lowered due to the rise of the altitude, and the pressure difference between the inside and the outside of the battery becomes larger. In this case, the battery pack may leak or the like. In this way, the safety performance of the battery pack or the power battery module, the power battery unit, the lithium battery, the nickel battery, the lead-acid battery and the like can be judged. According to the standard: UN 38.3, UL 1642, IEC61960 test standard
