The relocation was the big question on my mind.

The other is: when will they charge? Does this ship not run at night?

If it’s anything like the electric ferries that cross the Öresund beween Helsingborg and Helsingør, they grab charge while they’re unloading and loading at each terminal:

Each trip consumes approximately 1,175 kWh, which is nearly the same amount a residential home consumes in a month. In each port is a tower with a robot arm that connects the charging cable automatically every time the ship comes to the dock. The system charges 10.5 kV, 600Amp and 10.5MW. The batteries have a total capacity of 4,160 kWh, which means that we always have a surplus of electricity if for some reason we cannot load during a stop or if the transit takes more time than usual.

In Helsingör the ferries charge for approx. 6 minutes and in Helsingborg the ferries charge for approx. 9 minutes. This is enough to suffice for the journey across the strait.[1]

Side note: you can also charge your car on board from the boat’s batteries.

10.5MW on demand is wild

Also: installing the charging infrastructure. Special docking requirements for the non electric Spirit Of Tasmania were a big problem.

Q:

> when will they charge?

A:

> The ship... will travel between the ports of Buenos Aires, Argentina, and Colonia del Sacramento, Uruguay. The two cities are 60 kilometers apart, a distance it is expected to travel in 90 minutes.

> Direct-current charging stations will be installed at each port... A full charge is expected to take just 40 minutes.

Full charge is 40 but the charge for each journey is 6 / 9 minutes.

Big difference, since I imagine the turnaround time on a similar ICE ferry would be less than 40 minutes but more than 10.
