Between the M54 junction you’ve shown and Ellesmere Port is a distance of just 56 miles, so you could just top up before, or after the stretch.
The last fast chargers before the M54/A41 junction are at Corley services on the M6 ... 44 miles away. So now you're up to 100 miles, and it will be somewhat further to the next public fast charger at the far end of the A41 (depending on which way you're heading). Remember this?
Realistically, in France you'll probably need to pull into a charging point every 120 miles or so, and then charge for around 15 minutes, if you want to avoid range anxiety.
Not everybody drives a high spec. Tesla. 100 miles at fast A road / motorway speeds is close to maximum range for many electric vans.
or in your case, you’d start from home with 200+ miles in the ‘tank’…
I simply highlighted the A41 as being part of a major route ... nothing to do with me starting from home.
This is literally a non-issue, 54 miles is nothing… and as you said yourself there are still some rapids half way if absolutely desperate, but any decent car would just route you to a charger before or after.
As above it's not 54 miles. A 100+ mile gap between petrol/diesel forecourts would be unheard of on any major route, and the suggestion that traffic should divert off to search for a top-up elsewhere would rightly be ridiculed IMO.
