Qoolers has introduced BTMS CORE, a tube-based liquid heat exchanger for battery modules that the company says can reduce cooling-system weight by more than 70% compared with conventional aluminum designs while maintaining tighter thermal control.
The Czech company says BTMS CORE is designed to keep cells in the 20 °C to 40 °C operating window through direct tube contact, supporting both cooling and heating. According to Qoolers, the architecture improves thermal uniformity across the module, helping avoid hotspots that can accelerate degradation and undermine fast charging performance.
Qoolers claims BTMS CORE delivers heat transfer that is 3.4 times faster than conventional systems and improves efficiency by 29%. The company is also says the system is more than 90% recyclable, and its modular tube-based architecture is intended to simplify integration into series or parallel battery module layouts.
Qoolers is targeting EVs, energy storage, robotics and other high-power applications—basically any battery pack where thermal performance matters, but pack mass and packaging also matter. In battery systems, lighter cooling hardware can be an underrated win: every kilogram not spent on thermal management is a kilogram that can go to cells, payload or range.
