Technology Features & Specifications
Typically, the calorimetric testing of battery cells is based on measuring systems that are designed for specific battery cells. A full encapsulation is often chosen to achieve the required calorimetric, metrological accuracy and to limit any damage arising from cell failure. These special, battery-specific designs are quite expensive, adding to the costs in the event of "thermal runaway".
The technology on offer uses a modular system of almost identical assemblies which allows high-precision calorimetric measurements in a simple modular construction that is scalable for different battery sizes, and is particularly suitable for prismatic or pouch cells.
With a low-cost design, there is little financial loss if 'thermal runaway' occurs on a defective battery cell. In addition, as the surface size of the usual battery cells is variable, the modules allow for easy scaling of the surface area with an almost identical design. Different design sizes are covered without the need to purchase a new measuring device, and any loss due to 'thermal runaway' can be compensated by quickly reassembling a module set.
