Users need route planners (like Google Maps or others that add charging) to filter charging stations based on the specific charge cards they possess, to avoid manually checking and changing chargers while driving and to access discounted rates.
Yes I knew it was closed, it was a 15 minute detour, I was bored of the autobahns and lined up with a charge stop, also the Eifel region has nice roads. I normally never need to use a public charger, it was a faff and a half trying to find out which charge card worked on each charger to get the discounted rates. None of the route planners which add charging (including Google maps) filter to just the chargers which you have charge cards for, which adds to the faff as you're having to change chargers while driving. If you have to use your bank card you'll end up with hundreds tied up in pre-authorisation charges, yes you still get them for petrol/diesel but it adds up more due to having to stop more, as over the 1400ish miles I had to charge 16 times, while with petrol/diesel I would have needed to fill up like 4-5 times. Thankfully I was on my tod as on the first leg from the Cotswolds to Stuttgart (a little stupid to do it in one hit) 3 hours were spent charging and the car while not the slowest charging it's still a 400V car so far from the quickest to charge. I'd do the trip again but not in an EV, unless I get to try an 800V car that can get those 350-400kW charge rates. The car handled it perfectly and was happy to sit at 80MPH for hours on end, surprisingly it was more efficient at 80MPH on the roads over there, than on our motorways.
