HH Ferries Group has officially inaugurated the two 1991-built Ro-Pax vessels Aurora af Helsingborg (pictured) and Tycho Brahe as the world’s largest battery-powered ferries on the high-frequency route between Helsingborg, Sweden, and Helsingör, Denmark.
In each port, automatic land-based charging stations equipped with industrial robots perform the connection and maximise the charging period to enable efficient charging of each vessel’s 640 batteries within a few minutes.
The combined battery power of 8,320 kWh for the two ferries is equivalent to 10,700 car batteries.
The batteries are located on top of the ferries along with two deckhouses for transformers, converters, and cooling systems. From here, cables run to docking points at each end of the vessel, ensuring that the batteries can be charged swiftly and without complications at each docking.
Each ferry can carry 240 cars in addition to 1,250 passengers.
