Overview

The iso-BTC+ provides a comprehensive solution for characterising battery thermal behaviour under real-world conditions. It enables accurate measurement of heat generation across varying temperatures and operating scenarios, supporting the development of safer and more efficient battery systems.

With enhanced capacity for larger and higher-power batteries, the iso-BTC+ builds on established calorimetry technology to deliver deeper insight into thermal performance. These insights support the design of effective thermal management systems and improve the accuracy of thermal propagation models and simulations.

By combining precise calorimetric data with flexible testing configurations, the iso-BTC+ helps reduce development time, streamline testing processes, and accelerate product innovation across a wide range of battery applications.
