Altitude simulation tests

Definition

Altitude simulation tests are evaluations that subject solid-state batteries to low-pressure environments that mimic high-altitude conditions. These tests are crucial for understanding how batteries perform under conditions where air pressure is significantly reduced, which can impact their safety and efficiency. Conducting altitude simulation tests helps ensure that solid-state batteries meet safety standards and regulations for various applications, especially in aerospace and automotive industries.
