BTC-130 | Bench-Top, Battery Safety Testing, Adiabatic Calorimeter
The BTC-130 is a bench top adiabatic calorimeter designed for the safe and precise testing of smaller battery cells under thermal, electrical, and mechanical stress conditions.
- Enables thermal, electrical, and mechanical abuse testing of small battery cells
- Supports component hazard screening using small-volume test cells
- Helps define safe operating limits for battery cells
- Characterises differences in cell performance
- Supports research into thermal runaway mechanisms and propagation
Overview
The BTC-130 provides a compact, controlled solution for evaluating battery safety and performance at the cell and component levels. Its adiabatic design ensures accurate measurement of heat generation during stress testing, enabling deeper insight into thermal stability and failure mechanisms.
Ideal for early-stage research and development, the BTC-130 supports detailed hazard screening and performance comparison across cell chemistries and designs. By helping define safe operating limits and investigating thermal runaway behaviour, it plays a critical role in improving battery safety and reliability.
