Is it charging parking or EV Parking? From an enforcement perspective, the space should stay as EV parking because it’s much simpler. ALPR is used commonly for parking enforcement and it’s not worth the hassle to reprogram it based on the status of the charger. In no scenario does it make sense that an ICE vehicle can park there.
If the space is reserved for vehicle charging, that needs to be clearly signed. If it is for EV parking in general then this conversation is moot. Unless there’s a sign, there is no way to determine that the space is reserved for a repair technician - or even if the charger is working. Changing street parking rules based on whether a dongle is working is problematic.
It is slightly ambiguous because if it is labelled as “for EV charging” and you have an EV parked there and it is not charging, you are supposed to vacate the spot. So - if the charger is broken, the spot should be vacant. I can’t see parking enforcement being able to really handle that though unless there’s a connection between charger and enforcement.
But in that case, an ICE vehicle should still never park there.
It’s akin to delivery-only parking on a bank holiday. You still can’t park there even though the shop is closed.
