New lithium-ion batteries for submarines: Prototypes to be presented at EURONAVAL

October 19, 2018 – thyssenkrupp Marine Systems has developed a new type of lithium-ion battery system for submarines together with Saft, a manufacturer of advanced battery systems for industry. In an adapted form, the system could also be used for other maritime applications in future. thyssenkrupp Marine Systems will present the prototype at the EURONAVAL for the first time to the public.

Dr. Rolf Wirtz, CEO of thyssenkrupp Marine Systems: “The use of the new battery technology has enormous tactical advantages. We are entering a new era of submarine construction.” Compared to the known lead-acid battery, maintenance is negligible, and the lifetime is much higher. The new batteries depend little on the removable energy from the discharge currents and a submarine can – regardless of battery charge – drive at maximum speed.

In addition to a system design tailored to safety and to the special requirements of the operation in the maritime sector as well as a selection of safe cell chemistry, a series of tests has already successfully demonstrated the safety at battery cell and system level. Further intensive test series are planned until sample inspection.

Dr. Rolf Wirtz, CEO of thyssenkrupp Marine Systems: “The tests have been extremely successful so far. In the coming year, we want to have completed the sample inspections required for the approval.”

The system is designed as part of a study, which is carried out on behalf of the German procurement office, BAAINBw, to support the integration into new submarine projects for HDW Class 212 as well as re-fit solutions into existing weapon platforms. Concepts for an adapted design for integration into HDW Class 214 are planned. Due to the modular design of the battery system, it can in principal be adapted to fit into any naval application.

thyssenkrupp Marine Systems at EURONAVAL from 23 October to 26 October 2018 in Paris

You can find thyssenkrupp Marine Systems in the German pavilion in hall 2B, booth G45/G51 together with ATLAS ELEKTRONIK. As a leading systems supplier for non-nuclear submarines and naval surface vessels, we present a wide range of products in addition to the prototype of the new battery technology:

  • Submarine HDW Class 212A as well as Frigate Class 125 and Corvette Class 130; specifically designed for the German Navy and its mission requirements
  • MEKO ® Family (A-100 and A-200) and submarines HDW Class 209/1400mod and 214, products that enable our international customers to solve their operational challenges
  • Future kta naval systems consoles of the Combat Management System of the new submarine HDW Class 212CD
  • Capability enhancements such as HDW Fuel Cell System with reformer or IDAS

thyssenkrupp Marine Systems’ battery partner, Saft, will display its advanced battery technologies for submarines, torpedoes, civil marine, and other defense applications at the Euronaval show in booth F31.
