I have not been able to find any charge specs, all i found is the charger connect automatic when the ferry are docked.
I also assume it charge every time it is in port, cuz i could see winter weather meaning the 2 X 1000 BHP engines zap a lot more power, and it also have a couple of bow thrusters.
This is a joint venture between the municipality the local shipyard and EU, and truth be told it should have maiden voyaged in May or something, but something came up.
Take a lot more power to push a ship hull thru dense water, than it take to push a car thru air on low roll resistance tires.
Just found out the batteries are arranged in 2 packs, and made up of a total of 26800 lithium-ion cells of the make LeClanche.
One of the 2 motors.
Charger connection point.
The ferry are supposed to do 5 to 7 runs daily and charge in every port and then fully replenish batteries overnight, so there must be some loss of charge that the port visits dont have time to deal with.
I assume the time in port cant be more than 30 minutes or so for such a little ferry, but i cant recall how long it was for the diesel electric ferries i worked on in the 90ties, but the turn around was pretty fast for the driving passengers, and then we sailors had to swap some 20 - 30 brand new unmanned cars in every port too.
Apparently we have 2 other E ferrys, sailing on the Helsingor ( hamlet town ) to Helsingborg in Sweden, they also have 50 ton batteries ( watercooled )
The 640 batteries on each ferry can be ( fully i assume ) charged in 6 minuted on the DK side and 9 minutes on the S side.
Each crossing eat up 1.175 kWh in those 2 ferries.
BUT ! these are Hybrid not 100 % electric ferries,, but much larger than Ellen above.
Maybe thats why Trump come to Denmark soon, to steal our green thunder.
In the #2 video at the 1:20 mark you see one of the ferries i worked on, they was moved when out route closed to that route over there, we was offered to move with the ferries but i am not going near that part of my country unless i am in a Leopard 2 tank and coming to make big changes.
