thyssenkrupp Marine Systems (tkMS) and the Saft Group have developed a novel battery system for military submarines based on lithium-ion batteries. In addition to the low maintenance effort and the longer service life, the advantage is that the discharge current hardly depends on the energy that can be extracted. Therefore, a submarine can travel at top speed regardless of the battery charge level.

Das BAAINBw hatte tkMS beauftragt, in einer Studie ein Lithium-Ionen-Batteriesystem sowohl für den Neubau als auch für die Nachrüstung von bestehenden U-Booten der Klasse 212 zu entwickeln.

The sample tests required for approval are scheduled to be completed in 2019.
