Safety testing involves subjecting cell components, cells, modules, and battery packs to stress conditions to characterize their response.
The BTC-130 and BTC-500 are Battery Testing Calorimeters, which enable mechanical, electrical, and thermal stress tests to be safely carried out under adiabatic conditions on small and large batteries, respectively.
Mechanical stress: the BTC-500 can be equipped to perform a range of puncture tests
Electrical stress: the BTC-130 and BTC-500 can be fully integrated with charge-discharge units to support electrical stress tests. An external short circuit (ESC) option can also be provided
Thermal stress: the BTC-130 and BTC-500 maintain adiabatic conditions to help assess the component’s thermal stability. Thermal events that occur as a result of other stresses can be similarly characterized
The use of adiabatic conditions, where heat generated is retained within the system, enables the hazard assessment to be conducted under worst-case scenarios.
