Batteries of EST-Floattech on Hybrid Passenger Vessel “Schwielowsee”

Weisse Flotte Potsdam has commissioned Schiffswerft Bolle to build a battery-hybrid inland passenger excursion vessel

Weisse Flotte Potsdam has commissioned Schiffswerft Bolle to build a battery-hybrid inland passenger excursion vessel. EST-Floattech will provide the lithium battery packs for the ship, which is expected to be launched early in the second quarter of 2019.

The hybrid vessel, christened ‘Schwielowsee’, will be equipped with seating for 250 passengers, as well as full catering facilities and space for 20 bicycles on the foredeck. The electric vessel is propelled by two 120 kW electric motors, which are powered by 126kWh of lithium-ion batteries that can be recharged with shore power or diesel generators on board the ship.

Fully electric tour cruises on the Wannsee and Havelsee

The vessel will operate near Potsdam, primarily for tour cruises on the Wannsee and Havelsee lakes. Within the built-up areas of Potsdam and where residential buildings are located near the shore, the ship must operate solely on battery electric power. The ship is capable of fully electric battery-powered operation for one out of three Wannsee cruises per day.
