Battery swapping seems like it circumvents the slowness-of-charge problem, both for short haul (port and local urban service) and later for long haul. (Dealing with detours on the latter could be tricky though.)

5 - 10 minute battery swap vs however many minutes charging. Sure it reduces the load carrying capacity and/or range a bit, but it should still be viable for many heavy goods vehicles. Swapping makes it easier to manage battery condition and vehicle utilisation. Over time battery provision/swapping could be outsourced, so the transport company can focus on trucking, not on batteries and their needs.
