UK Firm Unveils New Liquid-Cooling Tech: 10-Minute Charge for 100kWh Battery, Compatible with Major EV Platforms

UK startup Hydrohertz has launched the Dectravalve, a multi-zone intelligent liquid cooling system. Validated by the University of Warwick, the system enables a 100 kWh lithium iron phosphate (LFP) battery to charge from 10% to 80% in just 10 minutes under 350 kW fast charging—68% faster than conventional methods. The system employs digitally controlled valves to independently regulate cooling across four or more zones, achieving temperature control accuracy of ±0.5°C and effectively addressing cell-to-cell temperature variations. Even at -20°C, it can complete a fast charge within 15 minutes. The technology also improves battery energy efficiency by approximately 10%, extending driving range by 30–40 km, and is projected to increase cycle life by 25%. Crucially, it maintains peak temperatures below 44.5°C—well beneath the thermal runaway threshold. Compatible with LFP, ternary lithium, and solid-state batteries, the solution fits over 90% of existing EV platforms and can be installed in just 30 minutes, suitable for both aftermarket retrofits and OEM integration.
