EV Plug / J1772 Adaptors
« on: December 23, 2016, 01:02:33 PM »

I think that the Zero is nice that it comes with a 110 V cable, but what about the EV Plug/ J1772 adapters?  The J1772 should come standard.

Here are the prices that I see on adapters and I think they are too much even though they are professionally assembled:

1. Zero -$300
2. Hollywood Electric- $400
3. Tucson EV - $165 - needs to be terminated, but comes with "pilot signal box"

Now these parts are basically copper, plastic and labor.  They should be able to be done for less that $90 with some volume.  I know some of these people are 'friends', but for the good of Zero and electric motorcycles, these adapters should be standard or driven to low cost.   

Can some one tell me about the J1772 'pilot signal'.  Don't we need a pilot signal on most chargers?  It would be tough to buy a $400 adapter and not have it work because it has no 'pilot signal'.

The pilot signal consists of 2(iirc) resistors and diode in the adapter. It just signals that something is plugged in and is ready to receive power.

You should be able to source on cheaper yes, I have more or less the European variant of it and it's €140. Which is reasonable because the type 2 plug alone goes for about €80 and the Schuko side is also weather proof etc.

I can ask my fabricator if he wants to make a batch of adapters but shipping to the US isn't cheap so it's probably only worth while if you ship multiple at once.

When you say "Tucan" were you referring to http://www.tucsonev.com/ ?

No problem.  I just wanted to confirm you were talking about something I'd already looked in to and not something I'd missed.  ;)

Both the Zero and the Hollywood electric adapters do not have pilot signals to my knowledge, so some charge stations must just ignore these signals, and others must require it according to the SAE J1772 standard.  That's fine until our $400 adapter does not work.

The 2 stage pilot signal is something the 99% of stations ignore.  Most just look for the 1 kOhm resistor on the pilot line to signal proximity or that its plugged in.  ChargePoint is over 50% of the market and they don't use them, Clipper Creek, Sema Connect and Blink make up another 40% and they don't either.  of the last 10% about 9 out of 10 don't use it either.  I have had it not work at a PEP station in las vegas once, and had an issue at an older GE watt station, but that is it.

That is good to know.

I really wanted a three way (or more) cable - travelling with 2 Zeros and maybe an electric hibachi grill. So I didn;t lok too deeply at the Zero J1772 adaptor.

So I emailed Tuscon for information... about the pilot switch.

I emailed Hollywood. (actually was about a 3 email volley back and forth... with additional information each time)
Hi James,
We do make custom plugs, it doesn't have to be just that configuration. The typical configuration I've suggested does appear to match your needs however if you would prefer something slightly different I'm happy to see what needs to be done to accommodate your needs.
Best regards,
Harlan Flagg
Hollywood Electrics

We also pay for the service, not just the part. Hollywood sets the service bar very high.

So that's twice in this thread "Tucsonev" was unspellable.

(I'm not really shifting blame - you have no idea how many times I type it "tiscon". )

I still think Harlan has the best customer service, and we willingly pay for it.

I also couldn't buy from "Tucsonev" as I cancelled my PayPal account because of Thiel's irresponsible political funding.

I read about that, and also how NOT using PayPal because of it is pointless.  He may have been one of the founders of the company, but he is no longer involved with it.  Basically, he doesn't give a rat's patootie whether you use PayPal or not, you're only punishing the CURRENT executives.

My wife picked up a J1772 adapter from "TucsonEV" for a Christmas present.  I have not had a chance to test it, and probably won't until the snow melts.  I ordered a dual cord version so I can use my on-board and my external (1x) at the same time (assuming it can handle the current, from what I read it looks like it can).

Looks well made, I have no idea if it produces the pilot signal or not.

Hey Steve, I have same plug but in single, it's worked at all the NH,VT and Maine stations I've stopped at. TUCSONEV has great customer service too.
