Cooling tech transforms EV performance with ultra-fast charging

The article discusses Hydrohertz, a British startup that has developed the Dectravalve, an advanced multi-zone battery cooling technology aimed at significantly improving electric vehicle (EV) performance. Unlike traditional cooling systems that treat the entire battery pack uniformly, the Dectravalve provides precise thermal management by independently heating or cooling individual battery modules. This approach maintains consistent temperatures across all cells, maximizing efficiency, reliability, and safety, which enables ultra-fast charging, extended battery range, and longer battery lifespan. The Dectravalve system consolidates thermal flow control into a single intelligent unit capable of managing up to four distinct outlets simultaneously, eliminating the need for multiple valves and complex piping. Its modular design allows easy integration into various applications, including EVs, data centers, and aviation. In tests with a 100 kWh Lithium Iron Phosphate (LFP) battery, the technology kept cell temperatures below 44.5°C with minimal temperature variation, compared to typical fast-charging peaks of
