KULR Technology Group has achieved operational readiness for its Fractional Thermal Runaway Calorimeter (FTRC) within its suite of battery safety and thermal management solutions after finalizing a commercial licensing agreement with the National Aeronautics and Space Administration (NASA) for the agency’s patent-pending FTRC solution.
Originally developed by NASA and refined by KULR’s engineering team led by NASA alumni and current KULR Chief Technology Officer, Dr William Walker, FTRC measures the amount of heat energy released during a thermal runaway event.
FTRC supports the discernment between (1) the total heat output due to thermal runaway and (2) the fraction of the total heat that is released through a cell’s casing versus through its ejecta material. The energy fractions are determined by post processing temperature vs. time for specially designed calorimeter sub-assembly groups.
The FTRC can induce thermal runaway with cartridge heaters, with a nail penetration system, or by combining the cartridge heaters with specialized test cells constructed with a built-in internal short-circuiting device (ISC).
This technology helps engineers and designers better understand these incidents and helps develop safer battery solutions to mitigate them. FTRC also allows engineers and designers to perform necessary testing experiments faster while also enabling them to utilize the variety of trigger methods noted above.
Following a one-year trial license from NASA, KULR’s new commercial license allows FTRC to be utilized by commercial-leaning companies, such as aerospace company Lockheed Martin, that wish to develop better and safer battery pack and battery management system (BMS) designs. This successful progression deepens the KULR’s position as a leading end-to-end battery safety design, testing, shipping, storage and failure-mitigation provider.
The commercial license for KULR’s FTRC specifically applies to 18650 and 21700 format Lithium-ion cells; KULR plans to enable pouch cell FTRC next month.
