It's an extremely unlikely situation, and the same thing can happen with an ICE. An ICE is, in fact, much more likely to experience mechanical failure. For either the solution is the same: you have to get towed.
Luckily if it's just needing a charge there are other options than a fast charge station. You can go to an RV park and get a faster than a regular outlet charge, or go somewhere with a regular power outlet and ask if you can use it. Either of those could require spending the night, depending on how much you need, but it is very unlikely to be required and they are possible.
