In reality though, almost nobody needs 250kW charging.

The average HGV will spend 9+hours charging overnight. It'll trundle from a warehouse to a supermarket (and back), possibly trickle-charging at both ends. It'll do maybe 4-5 round trips in the day, all of which could be covered by a single charge, but it'll probably get a bit of topping-up whilst material is unloaded.

There will be a handful of people doing London-Scotland trips who need a quick charge halfway, but that's not the duty-cycle most trucks work on.

It may also do some "light" journeys. For instance trailers to the Isle of Man generally get dropped off at Heysham, loaded by port tractors and forwarded by a local haulier on the island. So a Tesco tractor unit will take a loaded trailer to Heysham and either return to the warehouse unladen, or with an empty trailer - which will not tax the range too much.

Obviously they'll be a no-brainer for any sort of urban delivery where ULEZ or Congestion charging exists.

And we're assuming that diesel costs don't rise further/get taxed, or that electricity doesn't come down significantly (probably will, especially if they change how the wholesale market works, which they need to and will happen eventually).
