The instruction manual for my VW ID.3 said the car should not be parked for over 12 hours with less that 30% battery (and I should charge ASAP if arriving with less that 20). So I made it a rule to always arrive with at least 30%, since charging just after arrival on a road trip isn't always practical (and may not even be possible). Sometimes I've had to make an extra charging stop just for that. But the manual for my Elroq is much more vague on that point.

I'm off on a new 3 week road trip in a week. The first day is very long and with the one charging stop I'm planning, I expect to arrive with around 10%. But there it IS practical to charge on arrival, as there is an Ionity just a few minutes walk from my hotel plus a few other alternatives. The next day I have about 250 km, so if I start with 80% I may or may not have over 30% on arrival. And in that case I'd prefer to slow charge at the hotel the next morning.

Should I stick to the 30% rule or is that too strict, at least if I intend to drive again (and get opportunities to charge) the next morning? Mine is an Elroq RS if that makes any difference.

Personally, I wouldn’t worry about an occasional trip or journey where you might have to leave it in a low state of charge. In the example you’ve given above I would charge to 100% at the IONITY and remove the following day issue.

In this case I will probably charge to 90% which should be enough, and not a problem since I'll be charging anyway and have already reached my destination. But there have been cases on previous trips where I've had to make an extra stop to fill up, just to ensure I arrive with over 30%.
