yeah there should be an old-timey telephone where she has to call the charging company and give them her name and password, then ask them to begin the charge cycle.
I don't have the link handy, but there was a really interesting EV charging station guide from like 1920 that actually had phone #s to call if you needed the electricity turned on at the listed address (along with context like "this is the mechanics home phone, please only call during these hours unless it's an emergency")
