Quick question: If the vehicle is plugged in to a charger, can you pull away, if the charger is off?

I worry that we'll get in one morning and pull out of the garage, without remembering to unplug the charger first!


[This is a common risk for all EV/Plug ins, so I assume they won't "start" if there is anything in the charging socket.]

I've got a 2022 R4P and have never tried to do what you are describing but I understand your concern. I do know that when the charging cable is plugged in and you hit the "Start" button you get a prominent warning on the dash information center that "The Charging Port Door Is Open" You have me curious so I'm going to experiment and see if the vehicle will move or attempot to move with the cablke plugged in but not charging.

The car knows there is a charger plugged in and will not start (go into READY mode).

I suspected that was the case. .Good engineering to prevent dumb mistakes (LOL)

My assumption too - because too many of us could make this dumb mistake. Good to have it confirmed.

Yes car is not drivable when plugged in. It is interlocked.

Which brings up another point: there is no gas nozzle interlock. Why interlock the right side filler door, but not the left side filler door? Probably some regulation mandating the charging door but not the gas door due to legacy reasons. But it should not take much to implement.

Simple reason is that the car detects the charging cord plugged in. It does not detect the gas filler plugged in. In addition, fueling is a short term process. You are much less likely to jump in the car, turn it on, and try to drive away at the gas station. People have been fueling their cars for years. But when you have the charger plugged in overnight, by the next morning it is easy to forget, especially when charging a car is a new process.

The charging port door does NOT prevent you from driving. I am guilty of forgetting to close it after disconnecting my charging cable and driving away before I notice the warning on the display. It is the cable being plugged in that prevents you from being able to drive.

Part of the J1772 standard requires that the vehicle's locomotion be disabled whenever something is plugged into the charging port. The wording here is key: it's not "when charging" it's "when plugged in."

There's even a device being sold to emergency responders that's just an unpowered J1772 plug handle with no cable on it. You stick it in an EV plug and it disables the car. Every vehicle sold worldwide with the J1772 standard adheres to this lockout.

Thanks - and good to know about the emergency part.

Yup. Plus, with new technologies comes the opportunity to create new standard that address the problems of the past. While it doesn't happen often, people do drive off with fuel nozzles still in their car; it's a flagship of any Idiots in Cars video. Nowadays, fuel nozzle hoses have break-away links so cars don't drag the whole pump with them anymore. That was an easier solution at the time than trying to program in some kind of immobilization logic when a nozzle is in the fuel filler.

It wouldn't surprise me if someday regulations require immobilization when refueling with how advanced the average vehicle is.
