BTC-130 | Bench-Top, Battery Safety Testing, Adiabatic Calorimeter
The BTC-130 is a bench top adiabatic calorimeter designed for battery safety testing and hazard screening of cells, modules, and small battery packs. It enables precise evaluation of thermal stability, safe operating limits, and thermal runaway behavior under adiabatic conditions. With high speed data acquisition and flexible testing capabilities, the BTC-130 delivers critical insights for safer battery development.
Battery Performance and Safety Testing Specifications
Overview
Component Hazard Screening
Batteries operate across a wide range of environmental and stress conditions, making early stage hazard screening essential. As a bench top battery safety testing solution, the BTC-130 allows small volume cells and components to be evaluated under adiabatic conditions. This helps identify low onset temperatures, pressure increases, and gas evolution that may indicate thermal runaway risks.
Define Safe Operating Limits
Identifying safe operating limits is essential to prevent thermal runaway and ensure safe battery performance. The BTC-130 enables thermal, electrical, and mechanical stress testing to determine safe temperature ranges, maximum voltage, and current limits. High speed data acquisition up to 10,000 Hz ensures accurate capture of critical events during testing.
Explore Thermal Runaway and Propagation
Understanding how thermal runaway is initiated and how it propagates is key to developing safer batteries. The BTC-130 provides detailed data on decomposition onset temperatures and heat release, supporting a mechanistic understanding of failure events. This data can also be used to model thermal behavior and develop effective mitigation strategies.
Performance Testing
The BTC-130 supports performance characterization under extreme conditions. Automated cycling allows evaluation of repeated use limits, while tests such as puncture analysis provide insight into structural stability. This enables a deeper understanding of battery durability and safety under real world stress scenarios.
