Battery Thermal Runaway Testing
 
 

Thermal runaway of batteries adiabatically (ARC-type mode), to provide safe temperature limits and limits on discharge/overcharge rates using BTC. Different designs to allow both small scale testing and large packs (largest dimension over 55cm). Many unique features including on-line video capability.

Research Scale Battery Calorimeter/Phi-tec for batteries (ARC type)

The Phi Tec I for batteries is an adiabatic calorimeter for testing small batteries and battery chemicals is also produced which can provide data on maximum safe temperature to prevent thermal runaway and also, by connecting to a cycler, limits on discharge (current) rate and maximum overcharge (voltage). It works on the principles of the "ARC" device developed by Dow Chemicals more than 30 years ago.

For larger size batteries, see BTC (battery testing calorimeter).

EV Li-on Battery Thermal Runaway Testing: ''ARC-type'' BTC
EV Li-on Battery Thermal Runaway Testing: ''ARC-type'' BTC

This calorimeter enables the maximum safe temperature, maximum discharge rate (current) and maximum overchage (voltage), to be determined, above which thermal runaway explosion can occur, in different sizes and shapes of batteries.

Specially designed for safety testing of large and small scale (Li-ion & similar) batteries and components, the BTC is an evolution on standard "ARC-type" (TM) adiabatic calorimeters.
