Following MTU 4000s maybe on Type 218SG & future Type 212CD submarines of February 26, 2019 Anonymous commented:
2 x 2000 kW diesels for middle sized (2,000 ton) and 2 x 3000 kW diesels for large sized (4,000 ton) SSKs especially if the SSKs are equipped with advanced Lithium-ion Batteries (LIBs). Currently German made MTU or MAN diesels, each around 1,300 kW for submarine, are underpowered if the submarine wishes to achieve optimal quick charging performance for LIBs.
However [having 2 of] Japan's new KAWASAKI 12V25/31 (mechanical output 3,100 kW) would be most suitable for large (4,000 ton) submarines. From the viewpoint of power performance, a combimation of Toshiba NTO-LIBs and KAWASAKI 12V25/31s is better than Saft Lithium Iron Phosphate (LFP) LIBs married to MTU or MAN diesels.
BTW, on February 26, 2019, Toshiba announced the successful development of a new LIB anode for electric vehicles. The new battery a has higher capacity and longer life. This LIB is Toshiba’s second generation SCiB Niobium Titanium Oxide (NTO) battery. Toshiba aims for mass production in the early 2020s.
