@lol-lol I get your point about there being more trailers, but the point there is you just don't see many tractor units from the companies I listed hauling other people's trailers. Yes, I have seen the odd one or two here or there of, say, Turner's tractors hauling trailers with other names on them, but very few, so I think it is reasonable to assume that the majority of the HGVs listed as registered in the UK are for complete units, not just tractors with trailers making up the majority. Don't forget that a trailer has no power unit, so it is NOT registered, and from what I have seen and learnt from my time when I was a truck driver for a number of years, there will be significantly more trailers than trucks. When trucks arrive at a warehouse/factory, etc., with a trailer full for that customer, it is highly likely the driver will back the trailer to a loading bay and drop it, then pick another trailer, either empty or maybe full of new products produced at the factory, etc., and then transport them to their destination. And then that process starts all over again and again. When a truck is not moving, it is not earning, and with many transport companies, especially those with regular contracts moving stuff between factories and distribution centres, etc., it will very much be a 24/7 operation with drivers on shift patterns and changing over when a truck rolls into one of those centres. Anyone who watched the TV series about Eddie Stobart truckers will have seen that in operation. Now with a diesel, maybe 20 to 30 minutes of refuelling, and then that tractor could leave the complex with a fresh driver at the wheel and a new trailer attached. A 22 or 25 kW charger would stick in the battery in a short time. What, 10 or 15 miles of range? They will have to go with the largest chargers available, and that is where your massive load on the grid will come from. Don't forget that currently the grid struggles at times, and we only have currently a low percentage of electric cars on the road, and at times those with V2G capability are selling some of their cars' power back to the grid to help out. When you start getting HGV trucks demanding chargers of 350 kW and higher to keep trucks moving as much as possible, the grid will severely stretched. You say yourself that you was disappointed to see chargers at Exeter and Baldock were only 350 kW and hopeful of seeing 500 kW and even 1 MW arriving in the 12 months. So that will make matters even worse, not better.
