WATTALPS, a French developer of high-performance immersion-cooled batteries, has announced it is incorporating CEJN ultraFLOW quick connect couplings into its advanced battery systems. This integration aims to improve assembly efficiency, support robust thermal management and enhance the durability of battery packs intended for heavy-duty applications, including electric vehicles EVs operating in demanding environments.

WATTALPS designs and manufactures lithium battery solutions with ingress protection ratings of IP67 and IP6K9K. Each battery system is equipped with a battery management system (BMS) that meets automotive standards and is engineered for use in industries such as mining, maritime, agriculture, transportation, and construction.

The integration with CEJN’s ultraFLOW couplings follows successful completion of rigorous tests—including vibration, fire resistance, and immersion evaluations—demonstrating reliability under harsh operational conditions.

WATTALPS batteries are specifically designed to maintain optimal operating temperatures to reduce cell degradation and the resulting adverse effects on performance. The CEJN ultraFLOW couplings provide low pressure drop for effective coolant flow, a leak-free construction to prevent environmental contamination, and high resistance to shocks and corrosion. The couplings also facilitate simplified factory assembly, easier integration into various EV configurations, and adaptation to multiple battery architectures.

“It is crucial for the quality of our batteries that each supplier meets its commitments in terms of quality, cost, and delivery times,” said Matthieu Desbois-Renaudin, co-founder of WATTALPS. “The integration of CEJN’s couplings was driven by their differentiating features, including low-pressure drop, leak-free operation, and high resistance to shocks and corrosion.”
