I do not recommend this, both for the health of the cord, and the danger of entanglement. I'd say wrapping the excess cord under the hood in front of the charge port door, then shutting the hood is a better and safer trick. This way the extra length is hidden/protected, whereas with the tire method, the copper thieves don't need the 6 inches or so under your tire, they'll just cut it on either side.

I suppose if you are really worried, buy a decent 12AWG extension cord, and put the entire EVSE under the hood, and just run the "expendable" cord out. Beware that there is no built-in GFCI protection on the extension cord like there is on the J1772 cord, so using extension cords outdoors is not recommended.

For a long time, I've always plugged my converted Prius in via a socket inside the rear hatch, and ran the cord out the hatch. It wouldn't be too hard to install an additional J1772 inlet inside the rear hatch and charge my LEAF the same way.

Many outdoor plugs have GFCI (code requirement), which helps. I lopped off the end of an extension cord and wired on a GFCI plug. I'm using a Leviton 16593 plug I picked up from Amazon (currently $17.44).

Joule Thief posted a nifty way to secure an EVSE using $5 worth of parts from Home Depot yesterday on the Volt forum. He's attached a steel cable to the EVSE cable and locks the EVSE to the wheel.

I replaced the male plug on the L6-20R - 5-15p adapter cord I got from Phil with a GFCI plug (such as: http://amzn.com/B00207H5F4" onclick="window.open(this.href);return false;) plus purchased a 240vac inline GFCIwhen operating at that voltage:

The first person to figure out how to bolt the EVSE into the car, wire it in full-time (without disabling the J1772 socket), and add a retractable 120v extension cord will win an Oscar and a Nobel Prize!

This isn't too difficult. The easy way would be to just add another J1772 inlet back in the trunk (parallel with the front) and plug your EVSE in. Or build one of Chris' kits and wire that one in. All the wires you need to access are right there under the "hump" in the middle.

There would still be the small matter of having the hardwired EVSE disconnect from the vehicle when the power cord is unplugged. The LEAF is immobile if it detects the EVSE is connected.

Thats a minor detail, you could probably have a relay disable the "virtual" J-1772 interface (disconnect the pilot signal wire), when the AC is disconnected. Of course you lose all of the protection of the EVSE by doing this.

This might be the best solution, if Nissan starts selling them in the USA:

They are expensive, however. In the UK they cost £146.67 = $235.19!

Does it do that through the proximity detect of the mechanical connection of the J-1772 plug, or is it electrical? If it's based solely on the mechanical proximity detect, would wiring around the plug directly into the filter and control bypass it (or at least allow you to bypass it)? I don't think proximity detect is a signal on the J-1772 cable, its produced by the socket. So does it come in as a control signal into the car's internal control circuitry?

I guess the question gets down to: What would the control logic do if it saw power, pilot, and otherwise properly negotiated J-1772 protocol in the absence of the locally generated proximity detect? And is it easy enough to just rig a control switch on that if it is a problem?

A simple relay could remove the proximity detect signal when the AC is unplugged. All that would be required is a relay and 2 resistors.
