The charging infrastructure has changed a lot in the last few years. You can very comfortably travel all the way across Europe without even thinking about where to charge. There is a Tesla Supercharger every 50 miles or even less all the way from the Netherlands via Germany to Austria. And the same via Belgium to the South of France. And that's only Tesla, you also have Ionity building chargers, and Fastned, and you see more and more chargers at Shell and BP petrol stations.
It's been pretty great the past 3 years at least, just last summer I drove from Stockholm -> North Italy and had no anxiety about finding chargers on our way.
