Environmental Simulation & Vibration Test Solutions for
Environmental testing plays a vital role in the development and validation of modern battery systems. By simulating extreme conditions such as high and low temperatures, humidity, salt spray, and mechanical vibration, these tests evaluate battery performance, safety, and durability under real-world operating environments.
Such testing not only helps ensure safe and stable operation in electric vehicles and energy storage systems but also contributes to improving battery design, extending service life, and increasing energy density. It also supports compliance with stringent industry standards and safety regulations across the energy sector.
| Test | Purpose | Recommended equipment |
| Low-temperature test | Verifies battery discharge capacity and capacity retention under low temperatures (e.g., -40 °C), and evaluates whether solidification of the electrolyte or increased internal resistance leads to performance degradation. | Temperature & humidity test chamber Rapid temperature change test chamber |
| High-temperature test | Evaluates stability in high-temperature environments and prevents thermal failure, capacity loss, or internal pressure rise. For instance, testing at 55 °C-130 °C helps assess degradation and safety under summer-like extreme heat or prolonged loads. | High-temperature test chamber Temperature & humidity test chamber Rapid temperature change test chamber |
| Thermal cycling test | Simulates day–night and seasonal shifts to assess material fatigue and sealing reliability under rapid temperature fluctuations (e.g., -40 °C to 85 °C). | Temperature & humidity test chamber |
| Humidity test | Verifies battery resistance to humid environments. Evaluates risk of chemical reactions or short circuits caused by moisture ingress (e.g., 95% RH). | Temperature & humidity test chamber Rapid temperature change test chamber |
| Salt spray test | Simulates corrosion in coastal or deicing salt environments. Evaluates corrosion resistance of external housing and terminals, and identifies risks of liquid leakage or structural failure. | Salt spray test chamber |
| Vibration & shock test | Simulates vibrations and shocks during transport or vehicle operation. Assesses connection reliability, electrode damage, or breakage. | Vibration test system Combined temperature/humidity/vibration test chamber |
| High-altitude test | Evaluates insulation and heat dissipation performance under low-pressure conditions (e.g., at 4000 m elevation). | Low-pressure test chamber Altitude test chamber |
| Fungal resistance test | Assesses the ability of battery components to resist biological corrosion in humid environments. | Fungal resistance test chamber |
| Rapid temperature change test | Simulates extreme climate changes (e.g., 15 °C/min ramp rate), tests material reliability, and estimates service life. | Rapid temperature change test chamber |
