A wide range of cells that are well proven as both stand by batteries in nuclear-powered submarines and as the main propulsion source in diesel electric vessels are manufactured by Enersys in advanced flat plate or tubular plate construction.
Enersys technology in submarine batteries is the result of the experience gained in satisfying the changing needs of navies throughout the world using major brands like Hawker, VHB / Varta and Chloride.
Advancements in technology now takes navies into a new dimension, using thin-plate pure lead VRLA batteries for submarines, reducing the service requirements, achieving a true positive flow operation and improving safety.
Based on the experience of supplying main propulsion batteries since 1960, our latest designs, such as for the HDW class 212 and 214 AIP submarines, RDM Moray class and DCN Scorpene class, meet all requirements from shipyards and end customers.
Many years experience, computer aided design methods and in-house manufacturing of the most important components such as plates, pole bridges, cell boxes, lids and rubber liners enables us to be a partner with shipyards for submarine development, from first design idea to delivery.
Depending on the customer needs, we provide tailored designs based on tubular plate cells or flat plate cells with a choice of lead or copper negative grids.
Hawker flat plate batteries have been developed to meet the highest standards in a wide range of operational conditions.
The versatile flat plate range covers capacities from 5,150Ah to 11,750Ah and includes cells, which are well proven for both standby batteries in nuclear powered boats and as the main propulsion source in diesel-electric vessels.
Hawker's range has been further enhanced by the development of tubular positive plate batteries that can be assembled using either conventional cast negative grids or expanded copper negative grids, offering improved conductivity and a superior, high-rate performance.
Hawker's technology in submarine batteries is the result of the experience gained in satisfying the needs of navies throughout the world. Present day battery designs have evolved and proved themselves over many years, ensuring the highest demands are reliably and consistently met.
Design, development and manufacturing are all performed to the stringent demands of internationally recognised standards, such as AQAP 1 and BS5750 Pt.1.
Hawker's technology, in-depth experience and expertise is put to use by navies around the world, where its main propulsion batteries provide the power for many different classes of boat, including:
Hawker's designs ensure an uninterrupted lifespan with maximum safety and minimum maintenance through the use of specially formulated alloys in the manufacturing process. This minimises the evolution of hydrogen and reduces the need for topping-up the electrolyte.
Hawker's advanced technology gives an improved charge acceptance capability, permitting a faster recharge then many other designs. For submarine crews this has the important benefit of reducing surface exposure time when recharging.
A complementary range of well-proven peripheral units, including hydrogen eliminators, provides for maximum safety and utilisation of our batteries. Monitoring systems enable navies to automatically record the status of the battery at any time, ensuring optimal usage under any tactical requirement.
In addition, our after-sales service offers highly skilled, personal assistance at any time, at any location for commissioning, on-board installation, HAT/SAT, capacity tests and training.
