AES SAFE Required

Severity Level	Description	Severity Classification & Effects Criteria
0	No Effect	No effect. No loss of functionality.
1	Reversible Loss of Function	No defect; no leakage; no venting, fire, or flame; no rupture; no explosion; no exothermic reaction or thermal runaway. Cell reversibly damaged. Repair of protection device needed.
2	Irreversible Defect/Damage	No leakage; no venting, fire, or flame; no rupture; no explosion; no exothermic reaction or thermal runaway. Cell irreversibly damaged. Repair needed.
3	Leakage Δ mass <50%	No venting, fire, or flame; no rupture; no explosion. Weight loss <50% of electrolyte weight (electrolyte = solvent + salt).
4	Venting Δ mass >=50%	No fire or flame; no rupture; no explosion. Weight loss ≥50% of electrolyte weight (electrolyte = solvent + salt).
5	Fire or Flame	No rupture; no explosion (i.e., no flying parts).
6	Rupture	No explosion, but flying parts of the active mass.

PREVENT AND MITIGATE BATTERY EVENTS WITH AES SAFE

SAFE SYSTEM - WHY SAFETY ISN'T OPTIONAL

AES’s SAFE System is engineered specifically for battery testing, not adapted from general chambers. It prevents hazardous events before they occur and provides robust safeguards when they do.

Key prevention features:

Temperature-limited sheath heaters – keep heating elements below auto-ignition thresholds
Cell-mounted safety thermocouples – monitor abnormal temperature rise in real time
Customizable high-temp shutoffs – automatic alerts and proactive chamber shutdown
Setpoint controls & rapid rise detection – block unsafe test profiles and trigger early intervention

Built-in mitigation tools:

Atmospheric inertization – suppresses fire with inert gases
Low-flow pressure relief vent – safely exhausts cell gases
Graphite burst disk – emergency pressure relief for worst-case events

Optional abuse testing configuration:

Expands temperature capabilities for extreme test profiles while maintaining SAFE protection.

FAQ: Battery Testing Chambers

An environmental chamber for battery testing simulates real-world conditions so researchers and manufacturers can evaluate how batteries perform, stay safe, and last over time. Below are answers to some of the most common questions about these chambers.

What is the purpose of battery testing?

The purpose of battery testing is to measure performance, safety, and reliability under controlled conditions. Testing shows how batteries respond to stress factors like temperature swings, cycling, and environmental exposure.

What is the function of the battery temperature chamber?

A battery test chamber creates a controlled environment to replicate real-world conditions. It precisely manages temperature, humidity, and airflow so batteries can be safely tested for durability and compliance.

What types of batteries can you test in a battery thermal chamber?

Battery test chambers can test nearly all formats, including cylindrical, prismatic, pouch, coin cells, and full battery packs. This flexibility supports R&D through production-scale testing across many industries.

How does a battery test chamber ensure safety during testing?

A battery test chamber ensures safety by using systems that prevent and contain hazards during operation. Features include over-temperature protection, venting, fire suppression, and real-time monitoring of battery conditions.

What temperature range do battery test chambers cover?

Environmental chambers for battery testing typically cover a wide range of temperatures, from –70°C to +180°C. This range lets you simulate extreme environments, ensuring batteries can operate safely in diverse real-world applications.

Are battery test chambers used for electric vehicle (EV) battery testing?

Yes, battery test chambers are commonly used for EV battery testing. They handle large-format cells and packs, enabling manufacturers to validate performance, safety, and lifecycle under automotive conditions.
