Tesla/J1772 adapter available from Tesla's website

I'm sure the reason the adapter cable is so long is to avoid putting too much stress/torque on the inlet mounting cup. If that gets popped off the body panel, it's a real pain to get a replacement glued back on in the right.

I'm sure you are right Tom. however, if the cord was about 10 to 15" then it could be pre bent to hang closely down the side of the car with a small microfiber protection on the J1772 side to protect against scratches. it could even have a small hanger that fit into the bottom of the connector well for extra support. this should minimize the torque stress on the car inlet and not having the connector lying on the ground. and it would fit in the depression in the trunk floor....... it would have been a more elegant solution. but maybe this can be done by cutting the cable and mounting a new J1772 or mennekes inlet on the shorter cable and then using the left over for a Mennekes <> J1772 converter..........

I just bought the $750 adapter. I'm planning on using this to secure the cable to the tire while charging.

Nothing that a pair of sharp tin snips couldn't make like work of (unfortunately).

A shame Tesla couldn't mold an eye into the female J1772 housing so that you could use a bike lock or something like that to loop around a spoke of the rear wheel.

If that gets popped off the body panel, it's a real pain to get a replacement glued back on in the right spot. Even the ones that come from the factory aren't always aligned perfectly. That's why I gave up on the idea of hacking or replacing the cup to improve the cable clearance of the J1772 conversion.

What about having a single part without the cable, but spring-loading it in the center so that it would bend if something bumped into rather than breaking the charge port off the car?

Simple solution, Scott. Thanks! That's enough to deter the casual thief.

I'm not that worried about vandalism/theft. Unless the thread is buried somewhere, I haven't heard much about theft of cables for the copper from existing HPC chargers or vandalism. (Well, no more worried about it than I am about my car being keyed.) I'm just glad to have an adapter on the way, so I won't have to worry if a known HPC adapter has been changed to J1772.

While $750 is a crazy price for an adapter...why would anyone steal it? It's only useful to another Tesla owner isn't it?

One of our forum members made such a thing.
David Wegmuller's homepage :: J1772 Adapter


I recall hearing someone (Tomsax?) mention that the Tesla connector is effectively glued to the carbon fiber body, so if the adapter tube got bumped or pulled on too much it could have enough leverage to possibly break the connector off of the car. Dwegmull : how is yours working out?

I built it mainly as a proof of concept. It uses the plug from an MC120, so it is technically limited to 16A. In practice, the short run of wires inside the adapter should be able to carry 24A without overheating. I am a bit worried about the extra leverage on the car's socket. I'm thinking of adding a padded leg that rests on the bottom of the air inlet just visible in the picture you included.
I have yet to come across a J1772 charger (I'm not exactly seeking them out...). I know a few people who are about to take delivery of LEAFs so I will probably do my first test at their place rather than a public charger... I will insert a thermocouple inside the adapter and keep an eye on temperature during the first test.

With the Roadster's range, I have yet to need a public charger. I think I will keep my TM socket in the car as it may become a "collector's item"

Do you recon if Amphenol were asked, they could make an adapter in the length of the existing plug body, maybe less?

Early on, the rumor was that the Tesla adapter would be something like what dwegmull crafted. I'm assuming they had a good reason to not go that route since it would have been much nicer in several ways. Perhaps it's because of the leverage on the inlet mounting cup, or maybe it was a cost thing.

I brought up the adapter theft issue with Tesla in September, 2010. I know other owners brought it up as well. I was told Tesla doesn't think it's a concern. Their design indicates they don't think it's enough of a concern to do anything about it.

Obviously no one is going to steal one of these adapters to use it or sell it to a Roadster owner. Someone might steal it as a prank, or maybe for the copper. There have been a number of thefts of charger cords in California, presumably for the copper. At less than $3 per pound, the value of the copper in Tesla's adapter can't be much. It's probably not a big deal, but I'd rather not have to even think about having an adapter stolen.

It has always seemed to me that it would be rather easy to design a hinged sleeve that would have a small block mounted on the inner surface. The block would fit into the thumb switch slide area to prevent it from being slid back thus preventing removal of the connector from the vehicle or even just curious fingers from canceling your charge. The closure of the sleeve would just need tabs with holes for a small padlock.

Any interested designers?
