BTC-130: A Bench-Top, Battery Safety Testing, Adiabatic Calorimeter

TheBTC-130 (Battery Testing Calorimeter) is a bench-scale adiabatic calorimeter designed to enable the testing of thermal, electrical, and mechanical stresstests on smaller-sized battery cells. Evaluation of these tests facilitates the assessment of the safety performance of battery cells,the battery’s safe operating limits, and research and development into the mechanisms of thermal runaway. The BTC-130 also supports the use of small-volume ARC-typetest cells, enabling thermal stability screening of individual battery cell components under adiabatic conditions.

Features and Options

Type of Test

• Thermal stress:the BTC-130 enables the battery cell to be tested for itsthermal stability and for the characterization of associated thermal runaway events.

• Electrical stress:the BTC-130 can be combined with charge-discharge units to support overcharging and discharging testing. External short circuitscan also be applied. Resultant thermal runaway events can be characterized

• Mechanical stress:the BTC-130 canperform nail penetration puncture tests, while also characterizing the subsequent thermal runaway.

• High data rate acquisition, up to 10,000 Hz is available for characterizing extremely fast reactions. 100 Hz data acquisition and unique tests are available for compliance with GB/T 36276-2018
