Battery Tester iso-BTC (Benchtop Isothermal Calorimeter)

It is a calorimeter for evaluating the characteristics of battery cells under normal and long-term usage conditions. It supports adapters compatible with various cell shapes.

The iso-BTC (Battery Testing Calorimeter) is an isothermal calorimeter designed for the characterization of the thermal behavior and electrical performance of battery cells under normal and long-term usage conditions. It supports a variety of adapters that enable the analysis of diverse cell shapes. The iso-BTC can fully integrate a charge-discharge unit, allowing for the repeated automatic cycling of battery cells under various operating conditions while simultaneously recording both the electrical performance of the battery and the heat generated. It also enables accelerated degradation testing, allowing for the investigation of the effects of battery degradation on cell performance. The chemical properties of the battery, the composition of the electrodes, and the type of battery cell can also be investigated in cell development using the iso-BTC. Through thermal mapping (multi-point temperature measurement), users can identify areas of the battery that generate larger amounts of thermal energy, which are highlighted. In addition to characterizing the thermal behavior of battery cells at various temperatures and (discharge) charge rates, this information can be used to develop effective and targeted thermal management strategies within battery modules and packs.
