Vision Marine Technologies, a leading innovator in electric marine propulsion, announces the establishment of a production line for custom cooling plates in partnership with Calip Group, a leader in high-tech welding processes. Under this collaboration, Calip Group will supply components that enhance the thermal management of Vision Marine’s high-voltage (HV) marine battery packs. These custom cooling plates are specifically tailored to meet the stringent demands of marine applications, with production slated to begin in 2025.
Marine battery packs operate in environments that demand sustained, high-power delivery over extended periods. In contrast, most high-voltage batteries are designed to provide only brief bursts of peak power and minimal continuous output. Marine applications, however, require continuous operation at elevated power levels, resulting in significant thermal stresses that can degrade battery cells and shorten their lifespan.
To address these challenges, Vision Marine has developed specialized cooling plates adapted to the unique thermal requirements of marine battery packs. By improving heat dissipation and stabilizing cell temperatures, these advanced cooling plates help maintain consistent performance, enhance reliability, and extend the operational life of the cells—even under the most rigorous marine conditions.
“Overheating in a high-voltage battery designed for marine applications is a real challenge,” said Xavier Montagne, Technical Director of Vision Marine. “We decided to design our own specialized cooling plate to enhance pack stability and, of course, increase thermal efficiency.”
“We adapted our industrial tooling to meet the exact constraints of the battery and its specific assembly process,” said Thierry Giorgalla, General Director of Calip Group. “We’ve invested heavily in fine-tuning our FSW welding method to ensure a fully sealed cooling plate within tight tolerances. Calip is among the European leaders at mastering this high-tech process.”
Vision Marine’s E-Motion™ Powerpacks remain at the forefront of high-voltage marine battery technology. Among the first battery packs specifically designed for electric marine propulsion, they feature IP67-rated stainless-steel construction for superior durability, advanced thermal management systems, and modular configurations that seamlessly integrate into boats ranging from 18 to 34 feet. Vision Marine’s meticulous engineering has ensured that the E-Motion Powerpacks operate with unparalleled safety and reliability, with no recorded instances of thermal runaway to date. This impeccable track record, paired with new custom cooling plates developed alongside Calip Group, underscores Vision Marine’s commitment to proactive innovation and safety. Combined with full ownership of the tooling and strong production partnerships, the company is poised to scale manufacturing efficiently and reliably, meeting the rising market demand with confidence.
This development underscores Vision Marines’ commitment to delivering advanced, reliable, and practical solutions that foster the adoption of sustainable marine propulsion systems. This production agreement with Calip Group is yet another step toward meeting growing market demand for high-performance electric boating technologies.
