iso-BTC: A Bench-Top, Battery Performance Testing, Isothermal Calorimeter

The iso-BTC (Battery Testing Calorimeter) is an isothermal calorimeterdesigned for the characterization of thermal behavior and electrical performance of battery cells under normal and extended use conditions.It supports a range of adaptors which allows a wide range of cell formatsto be analyzed.

The iso-BTC supports the full integration of a charge-discharge unit, allowing for therepeated, automatedcycling of battery cells under a range of operating conditions, while concurrently recording both the battery’s electrical performance and the heat evolved. It can also conductaccelerated aging tests, allowing the effect of battery aging on cell performance to be investigated. Battery chemistry, electrode composition, and battery cell type can also be investigated within cell development using the iso-BTC.

Thermal mapping (multipoint temperature measurement) allows the user to identify regions of a batterythat generate greater thermal energy to be highlighted. Along with the thermal behavior characterization of the battery cell over a range of temperatures and (dis)charge rates, this information can be used to inform effective and targeted thermal management strategies within the battery module and pack.
