  • Define effects of environment temperature on battery heat generation to ensure product performance and safety
Battery Testing Funnel

Thermal behavior of cells, modules, and batteries is complex and must be well understood if products are to perform optimally and safely.

  • Inadequate thermal management may result in an unsafe product.
  • Excessive thermal management may result in a product that is unnecessarily bulky, heavy, complex, or expensive to build.
  • Inadequate understanding of thermal behavior may result in the setting of allowed usage conditions that are unsafe.  Alternatively, allowed usage conditions could be set which are overly cautious and place unnecessary limitations on product performance.

Data from the iso-BTC+ enables a deeper understanding of battery thermal behavior during:

  • Normal use conditions at various environment temperatures and during various charge/discharge regimes.
  • Abnormal but non-abusive conditions (e.g., mild overcharging).

iso-BTC+ data enables decision-making in the design of batteries, design of battery thermal management systems, and design of high-performance products.

iso-BTC+ data is used in thermal propagation modeling to predict the thermal behavior of large high-power batteries with complex geometries.

The iso-BTC+ supports thermal mapping during testing to identify regions of the battery which generate greater heat. This information can also be utilized to implement targeted thermal management strategies.

Data from the iso-BTC+ is used by cell and battery developers to assess the impact of chemistry, electrode composition, type of battery cell, and battery age on thermal behavior.  Measurements of heat produced during various charge/discharge regimes are used in simulations to provide deeper product understanding.

iso-BTC+ data on battery efficiency and heat evolved at specific temperatures, and charge rates can be used to characterize battery performance as part of a Quality Control process.  This approach is applicable to both cell manufacturers and battery integrators.

The iso-BTC+ will help you gain deeper knowledge to produce safer higher-performing batteries. Speak to one of our specialists today to discover how the iso-BTC+ can boost your battery intelligence with the enhanced characterization of thermal behavior and electrical performance.

The iso-BTC+ and the original iso-BTC are designed to measure heat-release profiles during battery charge and discharge testing, giving enhanced performance and lifespan data. The iso-BTC+ has been developed by building on the established capabilities of the iso-BTC; as a result, the iso-BTC+ can test even higher power and physically larger batteries.

This performance data will better inform the efficient design of thermal management systems, yielding safer, higher-performing products. A deeper understanding of battery thermal behavior can also enhance thermal propagation modeling/simulations leading to time savings during the battery and product testing.

Both the iso-BTC+ and iso-BTC work with a range of cyclers and battery formats to precisely quantify the thermal behavior of batteries during real-world use conditions. Electrical and thermal measurements are made simultaneously at defined temperatures, including charge/discharge profiles, all controlled by versatile and easy-to-use software.
