If there are not charging stations check for RV parks along the way home. They often have 220v. Put a 220v plug on an EVSE to use it as a portable (that is what I did) or get your Nissan unit converted to use 220v.
But really I'd press the dealer to pay for towing to your house or to within battery range.
