Submarine Batteries


SUNLIGHT Submarine BatteriesBeing equipped with robust knowhow and long-lasting experience
 in the energy storage sector, we are now ranked among the top global players in the design and production of batteries for all types of conventional submarines (eastern and western type), utilizing all available technologies.

Our innovative approach to the high demanding energy needs of this sector, our capability for designing and developing inhouse new prototype cells for batteries, as well as new complementary products and accessories, such as the Battery Monitoring System (BMS) and the Hydrogen Eliminator, in combination with a specialized Technical Support team, makes us the best choice for submarine batteries.

The design and development of more than 25 different cell types and the delivery of 60 battery shipsets to navies worldwide are the strongest evidences for our expertise and cumulative experience in the submarine battery sector. Indicatively, we have manufactured submarine batteries for:

  • Greece
  • Ιtaly
  • Egypt
  • Germany
  • France
  • Ukraine
  • Pakistan
  • Peru
  • Poland
  • Sweden
  • South Africa
  • Portugal
  • Korea
  • Netherlands
  • Equador

Technologies

Different types of lead-based technologies are applied for the manufacturing of submarine batteries in order to meet the various demands and sophisticated requirements in terms of energy, performance and reliability. More specifically, the following technologies are available:

  • Long plate positive tubular plate / Negative plate lead
  • Long plate positive tubular plate / Negative plate copper stretch metal (CSM)
  • Double decker positive tubular plate / Negative plate lead
  • Double decker positive tubular plate / Negative plate copper stretch metal (CSM)
  • VRLA long plate (CSM) / Gel electrolyte
  • Tailor-made cells: all the above mentioned technologies can be adapted to meet the tactical demands of the submarines and meet specific requirements.

 

Designs

  • Western type submarines: U206, U209, U212, U214, U209P, U210, Scorpène, Agosta, 6YOH, Sauro, Walrus, Kobben
  • Eastern type submarines: Romeo, Foxtrot, Kilo
  • Very low H2 evolution during operation
  • Internal cooling system with great efficiency
  • Container and lid are manufactured in house with a very sophisticated method. The container walls are thinner, which gives the container less weight and more volume, thus more active material for increased performance. The design of the container has successfully passed the BV430/85 and BV430/73 Shock Tests at BWB
  • Pole bridges are made of electrolyte copper to increase conductivity. The specially designed geometry of the pole bridge ensures maximum heat transfer during the cooling process
  • Cells exhibit a very low operation temperature during battery activation and charging
  • Cells’ plates have excellent dry charge conditions
  • The improved agitation system inside the cell protects the battery from sulphation problems and increases the electrical performance
  • Each cell is equipped with an easy maintenance service plug with an integrated ceramic filter. The ceramic filter is specially designed with improved anti explosive capability

• Robust and durable construction
• Optimum reliability
• Excellent performance both at low (patrolling) and high rate (maneuvering) operation
• Long design life
• High capacity
• Enhanced current capability during discharge
• Law gassing
• Excellent shock resistance
• Recyclable
