I think this ferry between Helsingborg (Sweden) and Helsingør (Denmark) does it in the coolest way. Since 2018 the ferry has been running on batteries. Whenever it docks into any of the two ports, an ABB robot connects the charging cable. One real cool thing here is that they have gotten it to work for 4 full years in a northern climate. That means a lot of extreme weather edge cases. https://youtu.be/l93i87pZWhY?t=13 https://youtu.be/l93i87pZWhY?t=13
