Video: DSME 2000 & KSS-III Submarines with Lithium-ion Batteries

Following November 4, 2019's DSME 2000 Concept Submarine, Specifications, Potential Customers below is a MADEX 2019 video (link) with a South Korean engineer commenting on the DSME 2000 and KSS-III. Then a Hanwha Defense representative provides details of the Lithium-ion batteries for submarines that DSME is using and marketing.


-  at 1 minute 10 seconds Xavier Vavasseur (Chief Editor, Naval News) with Jejun Park (Chief
   Engineer, South Korea's DSME) introduce the concept DSME 2000 submarine. At 2,000 tonnes it
   is a size between the DSME 1,400 tonne Chang Bogo (Type 2009 variant) exported to Indonesia
   and the 3,000 tonne KSS-III DSME is building for the South Korean Navy.

   The DSME 2000 will have the latest IT and Lithium-ion Batteries, an AC magnet motor and
   X-plane rudders. As it is a concept design it can be configured with  the foreign customer's choice
   of weapons [and presumably with the option of Fuel Cell AIP?].

-  5 mins 4 secs Jejun Park briefs Xavier about the KSS-III - with a KSS-III Batch 1 being
   launched on September 14, 2018. The KSS-III Batch 2s will have Lithium-ion Batteries which
   will increase fully submerged endurance by several days.

-  5 mins 47 secs display of the Lithium-ion Battery arrangement for the KSS-III Batch 2 (on which
   many DSME 2000 components will be based). Monnhee Kang of Hanwha Defense displays the
   contrast between:
   =   Lead-acid Batteries [eg. used for Australia's current and future subs] only having 2,000 "cycles"
        [a cycle being one semi-submerged, diesel engine battery recharging "snort"]. See reference.
   =   compared to Samsung SDI Lithium-ion Batteries that have twice the service life (that is up to
        4,000 cycles "or about 10 years of operational life").
   =   Monnhee points out a Samsung SDI Lithium-ion battery tray, each with 24 cells. With 100
        modules in the front of a KSS-III Batch 2 and 100 in the back. South Korea has been conducting
        land based tests of whole battery pack for submarine since 2016. South Korean industry reps
        indicated all has gone according to plan.
