Re: Safe Display of LEAF - Lock out Motion

If the L1 charger is connected to the car, but not powered, does the presence of the proximity pin prevent driving?

If so, it would be easy to make a dummy "plug" that just goes into the J1772 port on the car and spoofs a present-but-unpowered EVSE.

Yes, I confirmed this at the Drive Electric tour here in Hillsboro. If the J1772 connector is plugged in, shorting the proximity pin, the light indicating that it was plugged in popped up on the dashboard and prevented me from putting the vehicle in drive. :D

However, it is too easy for a "visitor" to unplug the e-nozzle.
I would hope that we can discover a more-sure solution.
So maybe what you want is a switch, hidden down in the engine - er, motor - compartment that provides a contact simulating the one the J1772 connector provides.

I've driven it with the door open and seat belt off when I wanted to align it in the garage better. It drives with the door open.

Sounds reasonable.
For a "no-modification" solution, what does the proximity pin require? Is it a magnet, dry contact switch, or electrical connection?
A single push-pin with a pull tab should be able to do it regardless. Put some tape over it or just don't call attention to it, and nobody (friendly) should mess with it.

Per the J1772-2010 specification, between pin 3 (ground) and 5 (proximity), you need to place a 480 Ohm resistor (or equivalent resistance).

Good to know - I can't remember now where this came up, and I apologize for continuing the rumor. I definitely won't repeat it again! :)

It might require 150 ohms (the 330 in series is normally shorted by switch "S3", and the 150 becomes 480 only when pressing the e-nozzle's "Release Latch" button.

But, 480 ohms MIGHT work to immobilize the EV.

However, one typically wants to be charging while displaying the car, and visitors might unplug the e-nozzle to try it out.

But, a padlock on the nozzle should work fairly well.

I was hoping for a more subtle solution.

A resistor on some clips would make a heck of a prank, eh?

Totally correct! I forgot about the switch bypassing the 330 ohm resistor!
