About Qoolers s.r.o.

Qoolers is a Czech deep-tech scale-up developing next-generation Battery Thermal Management Systems (BTMS) that set new standards in performance, weight, safety, and scalability for the global battery industry. We specialize in advanced thermoplastic liquid cooling solutions optimized for cylindrical, prismatic, and pouch cells. Our modular BTMS CORE (for modules) and BTMS MAX (for packs) deliver 60–70% weight reduction versus traditional aluminum systems, enable more battery capacity in the same package, and provide superior thermal uniformity with direct cell contact cooling. Key technological advantages: - Inherent electrical insulation eliminating short-circuit risks - High design flexibility with custom serpentine channels - Non-flammable materials with self-extinguishing capabilities - 90% recyclability and lower CO₂ footprint - Active development of electronically controlled immersion cooling for next-generation high-energy-density packs Backed by real engineering: - Over 1,000 physical prototypes built - Extensive ANSYS Fluent CFD validation (CHT, transient, FSI) - Independent case study proving superior thermal performance vs. aluminum - Automotive-grade quality pathway (ISO 9001 certified, targeting IATF 16949) We are positioning Qoolers as the leading European innovator in Battery Thermal Management. Our technology solves critical challenges in electromobility and energy storage — faster charging, extended range, enhanced safety for high-silicon cells, and significant weight savings. We actively seek strategic partnerships with Tier-1 suppliers and OEMs who demand proven, scalable, and truly innovative thermal solutions. Real Hardware. No Hype.
