Testing that Reaches the World

Thermal runaway is a chain reaction within a battery that leads to rapid temperature increases, which can result in fire or explosion.  It typically occurs when internal temperatures exceed safe limits due to factors like overcharging, internal short circuits, or external heat exposure.

Understanding and preventing thermal runaway is essential for developing safe and reliable battery systems.  Clark Testing provides thermal runaway testing services that are designed to evaluate and mitigate risks and ensure your batteries perform safely under all conditions.

The test engineering team at Clark provide testing services to identify potential thermal runaway scenarios helps prevent catastrophic failures, protecting users and environments.  Our test engineering and analytical chemistry team help product engineers design improvements and enhance the resilience of your battery systems proving the safety and compliance of your batteries through rigorous testing.

Our Thermal Runaway Testing Services

1. Calorimetry Testing: Using differential scanning calorimetry (DSC) to analyze thermal behavior and identify decomposition temperatures of battery materials.
2. Battery Module Testing: Subjecting complete battery modules to controlled conditions to assess how they respond to thermal stress and detect potential runaway incidents.
3. Overcharge Testing: Evaluating battery performance under overcharge conditions to simulate and assess the risks associated with charging failures.
4. External Heating Tests: Exposing batteries to elevated temperatures to observe failure modes and thermal responses, helping to establish safe operating limits.

• UL 9540A  This standard is used to evaluate how battery energy storage systems respond to thermal runaway and fire propagation. It helps manufacturers comply with regulations and is useful for developers and engineers to verify a product's ability to prevent fire.
• UL 2580  This standard is used to assess the safety of lithium-ion batteries used in electric vehicles. It covers a range of safety requirements and test methods to help ensure the safety of these batteries in a variety of conditions.
• IEC 62660-2  This standard includes a capacity discharge test that measures the performance and capacity of lithium-ion cells. The test involves discharging cells at specific rates while monitoring the voltage, current, and capacity.
