iso-BTC | Bench-top, battery performance testing, isothermal calorimeter
The iso-BTC is an isothermal battery calorimeter designed for precise battery performance testing and thermal characterization under controlled conditions. It enables detailed analysis of heat generation, efficiency, and charge discharge behavior across a range of temperatures and operating conditions. The iso-BTC provides critical data to support battery development, quality control, and thermal management strategies.
Battery Performance and Safety Testing Specifications
Overview
Characterize Cell Performance
Battery performance is influenced by factors such as chemistry, electrode composition, cell type, and aging. The iso-BTC enables detailed battery performance testing by measuring efficiency, charge discharge capacity, and heat generation across varying temperatures and rates. This data supports accurate modeling of battery behavior and provides deeper insight during cell development.
Quality Control and Cell Characterization
The iso-BTC supports consistent and reliable characterization of battery cells for quality control purposes. Key parameters such as efficiency and heat generation at defined temperatures and C rates can be measured and used as performance benchmarks. This allows manufacturers to validate product specifications and enables battery integrators to verify cell performance throughout the supply chain.
Thermal Management Analysis
Effective thermal management is essential for safe and reliable battery operation. The iso-BTC measures heat absorption and evolution during charge and discharge cycles, helping to identify conditions that may lead to overheating or performance imbalance between cells.
Thermal mapping capabilities highlight localized regions of increased heat generation, providing valuable insight into heat distribution within cells, modules, and packs. This data supports the development of optimized thermal management strategies to improve safety, performance, and longevity.
