M/FTycho Braheis a Danish battery-electriccar-ferryowned byØresundslinjenthat operates on theHH Ferry route.It has been in use since 1991. The ship is bidirectional, which means it can change direction without turning around, so no time is lost for this. The ship is also able to accelerate and decelerate quite quickly to and from her maximum speed of 14 knots.
The ship is named after the Danish astronomerTycho Brahe.M/FTycho Brahewas built byLangsten Slip & BåtbyggeriinTomrefjord,Norway.The ship is owned and operated byØresundslinjen.Between 1991 and 1997, M/FTycho Brahewas owned byDSB Rederi.
The ferry can carry 1250 passengers, and either 260 trucks, 240 cars or 9 passenger train coaches at one time. It was built with three railtracks inside, with a total length of 266 meters.
Conversion to electric
[edit]M/FTycho Brahehas a sister ship,M/SAurora af Helsingborg.The two ships were originally diesel-powered, but were converted in 2017 to fullelectric propulsion.Each ship has a 4MWhbattery, weighing 57 metric tonnes, located at the top of the ferry between the chimneys.[3]The batteries are rechargedfrom landby a robot arm when docked,[4]at 10.5 MW(10.5 kV,600A) for 6 minutes in Denmark and 9 minutes in Sweden. Each trip uses about 1,175kWhand is scheduled to last 20 minutes similarly to the diesel ferries.[5]Two of the four Wärtsilä-Vasa 6R32E diesel engines have been removed from each ship, with the other two as a backup system, not for daily operation.[6]
