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.
