Real Thermal Management System (TMS) is Finally Here!

Currently, battery packs using PCM (Phase Change Material-Wax), potting compound, thermal pads, ceramics as thermal management solution have poor heat removal rate and hence not suitable for high performance and fast charging applications.



Introducing GrafX: AIS 156 Compliant TMS for Lithium-ion batteries.

GrafX - Our proprietary TMS is a composite material made of Graphite + PCM with very high thermal conductivity and heat storage capacity. GrafX ensures fast heat removal rate, uniform heat distribution, cooler temperature and unmatched thermal runaway mitigation 24x7 in a simple, cost effective, modular design for all battery types (Cylindrical or Prismatic or Pouch cells). Our first customer has successfully passed AIS-156 (Phase-2, Amendment 3) Certification testing, including Thermal Propagation Test using CaloryTech’s GrafX thermal management system.

CaloryTech is on a mission to make Lithium-ion Batteries Safer and Long Lasting with Superior Performance!

Introducing GrafX TMS: Best-in-class and simplest Thermal Management System (TMS) for Lithium Batteries for electric 2W, 3W, Drones, ESS, Telecom Towers, Agri Machinery etc. for all cell types – Cylindrical, Prismatic, & Pouch cells.


GrafX – A Powerful Product Differentiator
Defend Against Battery Fires with GrafX

GrafX is a passive Thermal Management System (TMS) that offers 24x7 thermal runaway mitigation for Lithium-ion Batteries, thus drastically reducing the chances of fire in Electric Vehicles. GrafX does not require external power or BMS to activate the thermal safety protection system, GrafX works on a standalone basis.

  • Compact TMS where active cooling system like liquid or forced air cooling is not a practical solution because of space and weight constraints ex. 2&3 Wheelers, Drones, VTOL (Vertical Take-Off and Landing vehicle) etc.
  • Tested for much stringent standards than those required for thermal propagation test to obtain AIS-156 Phase-2 certification
  • CaloryTech has performed numerous inhouse lab tests to demonstrate the superiority of thermal runaway mitigation and prevention of fires

Do Fast Charging or Fast Discharging Under 30 min – We Take the Heat, You Stay Cool!

GrafX can handle large amounts of heat generated during fast charge and fast discharge for all weather conditions including hot summer so that the batteries stay cool and last longer.

Maintaining a lower and uniform battery temperature in the module or large format cells (cylindrical or prismatic cells) even during summer season is critical for safety, optimal battery performance, BMS control, longer cycle and calendar life.
