Rechargeable Li-ion batteries modularly divided into SmartPowerBlocks™ (SPBs bring highest capacity and combine safety, reliability and low weight. These batteries are available in three different standard diameters: 260mm, 310mm, 416mm (dimensions without pressure housing). They are partly type-qualified according to MIL-STD, API17F or international standards. The batteries can be qualified to UN T38.3 upon request.
Typical applications for our Vehicle Batteries:
• Underwater vehicles: AUV, ROV, submarines
• Surface vehicles: USV, boats
• Underwater equipment: monitoring stations
• Smart sensor power supplies
We offer COTS (Commercial Off The Shelf) and customised battery solutions. Increased safety is achieved by dividing the battery into self-protected SmartPowerBlocks™ (SPB) modules with their own BMS protection. We only use industrial 18650 cells with the highest energy density, which themselves have extensive protection such as overpressure valves, overcurrent and temperature protection, housed in stainless steel shells. In contrast to pouch cells / Li-Pol cells e.g. used for pressure-neutral batteries, these batteries can be certified and undergo shock and vibration tests, e.g. in accordance with MIL-STD or API17F.
As a manufacturer of corrosion-free and lightweight titanium 1 atm pressure housings (not oil-filled), the batteries are easily scalable with low weight under water. The battery is easy to install (self-supporting) and has a low cable count. This saves buoyancy and thus considerable costs, simplifies the system design and offers extremely high safety even under rough sea and shipboard conditions.

150V 9kW peak AUV battery with diagnostic unit and PowerCharger.
The FlatFish project is a venture undertaken by the German Research Center for Artificial Intelligence (DFKI), the Brazilian Institute of Robotics (BIR) and Shell. It aims at designing an autonomous underwater vehicle (AUV) for repeated inspections of oil & gas subsea structures whilst being submerged for extended periods of time. For the evaluation of energy and high-bandwidth data transfer while submerged, the docking station demonstrator was equipped with optical data transmitters and electrical contacts for battery charging, witnessed by representatives from Shell (Rio, Brazil and Houston, USA) and from SENAI-CIMATEC (Salvador, Brazil). ©DFKI/Ground Truth Robotics, Florian Cordes
Li-ion battery for a fuel cell UUV. SubCtech has developed and built the Li-Ion battery for an innovative long range Unmanned Underwater Vehicle (UUV). The UUV is being developed by Cellula Robotics Ltd. under the Canadian All Domain Situational Awareness (ADSA) Science & Technology (S & T) Program developed and built. Known as “Solus-LR”, the UUV will have a target range of 2000 km and is designed to stay submerged for multi-month missions. The Li-Ion battery system works with the fuel cell system, taking power peaks and ensuring optimum power system operating parameters. © Cellula Robotics
Amogh – the dependable underwater surveillance vehicle Amogh (Hindi: Dependable Work Horse) is a third generation Autonomous Underwater Vehicle (AUV), designed and being developed in collaboration with Larsen&Toubro, Mumbai (India) and Edgelab, Italy. The AUV is designed to comply with International Hydrographic Organisation Standards for Hydrographic Surveys and IMP regulations for the safety of navigation. The containerized design with built-in LARS and AUV maintenance support system is suitable for ease of deployment and installation. Amogh is loaded with the latest state-of-the-art sensors, payloads, propulsion and energy system, which make it a best-of-class AUV for hydrographic and underwater surveillance, and reconnaissance operations.

The $7 million Shell Ocean Discovery XPRIZE is a global competition which challenged teams to advance deep sea technologies for autonomous, fast, high-resolution ocean exploration. Texas A&M student team named finalist in Shell Ocean Discovery XPRIZE competition. Marlin carries an on-board intelligence system, a long-range optical and acoustic communication and reference system, an ultra-high resolution 3-D scanner, inertial navigation system, Doppler velocity tracking, chemical sensors to monitor the environment, a pump jet propulsion for high speed operation, forward dive plane for quick descents and a wave energy conversion system. To operate all of this technology, Marlin is also equipped with a 48 kilowatt-per-hour battery system, which is more than the average household uses per day. © Deep-Down / Oceaneering
An analogous mission as preparation for future explorations of Europa. The project Europa-Explorer is a pilot survey for future missions to Jupiter’s moon Europa. It focuses on the aspect of navigation of robotic systems on and espe-cially under Europa’s surface. Below Europa’s ice shield (thickness between 3 and 15 kilometers) an ocean comprised of liquid water is expected. For the exploration of this ocean a fully-autonomous system is necessary due to the long run-time of communication from earth to Europa (33 to 53 minutes). SubCtech has developed and delivered the battery system. © DFKI, Jan Albiez
