Autonomous underwater vehicles (AUVs) play a crucial role in modern naval operations, requiring reliable, high-performance energy sources to sustain extended missions in challenging underwater environments. SubCtech, a leader in marine power solutions, is at the forefront of this technological evolution with its state-of-the-art, certified AUV/drone batteries and groundbreaking underwater storage solutions for resident stations.
AUV BATTERIES
SubCtech’s AUV battery systems are designed to meet the stringent requirements of naval defense operators. These lithium-ion-based power solutions provide high energy density for long-endurance missions, that demand extended cycle life, modular adaptability, and the highest of HSE standards, ultimately delivering optimal operational flexibility.
Available in various configurations, they offer voltages up to 1000 V and capacities tailored to mission-specific demands. Their pressure housings enable safe deployment in any deep-sea environments, ensuring reliability under extreme conditions even on board or during recovering.
- Key technical specifications include scalable modular design, allowing seamless integration into different vehicle platforms. We provide MW ranges for the next-gen XXL AUV.
- The Smart Battery Management System for enhanced safety and real-time diagnostics enhance your mission opportunities, enables high peak currents or consistently high speeds.
- The fast-charging capability minimize downtime and enables rapid-reaction times.
- The titanium enclosures and connectors are designed for deep-sea-deployment, extended endurance, and absolute shock resistance.
STORAGE & BACKUP SOLUTIONS
One of the most promising innovations in naval intelligence is the development of underwater storage, serving as docking stations for AUVs or resident monitoring stations. SubCtech is pioneering this concept with its subsea energy storage systems, designed to provide a charging and data exchange hub for extended missions.
A key feature is underwater charging, which eliminates the need for top side operation and support vessels, reducing maintenance requirements and enhancing durability in harsh marine environments. These docking stations will allow AUVs to recharge autonomously and upload mission data, significantly extending their operational time in the field. The systems will be equipped with high-capacity battery modules to support multiple AUV charging cycles, converters, and control for unattended operation and extreme ruggedized construction.
SubCtech certifies with accordance to international standards such as MIL-STD, UN T38.8, DNV, or NAVSEA.
MISSION ENABLERS
As naval defense agencies continue to integrate autonomous technologies into their strategies, power and storage innovations become critical enablers of mission success. SubCtech’s advanced vehicle batteries with support of subsea docking stations will play a pivotal role in ensuring sustained, efficient, and intelligent underwater operations. These advancements will not only enhance maritime security but also pave the way for the next generation of autonomous naval intelligence systems.
