Re: [EVDL] Charging adapter for J1772?

[Chris Tromley via EV]

Noob question here.  Isn't the EVSE's current capability part of the J1772
handshake?  Even if there's no way to automatically throttle your EV
charger, could you query the EVSE through the plug and dial down your
charger to the appropriate query manually?  Or at least use the EVSE signal
to prevent your charger from attempting to draw too much and pop the
breaker for the EVSE?

I have the Tucson EV 1772 adapter with the box on my conversion. Very satisfied 
with the quality.

Re: [EVDL] Charging adapter for J1772?

[Mr. Sharkey via EV]

>> Anybody have experience with this or any other J1772 adapter?

Like several of the other respondents, I built my own after the local 
utility put in two 30 ampere EVSE pedestals at the front of their 
office in town.


The components to signal the EVSE to begin charging aren't at all 
expensive, one resistor, and one diode. The expensive part was the 
J1772 connector of the  input end of the adapter ($69 on fleabay). 
The whole thing is contained in a weatherproof cast aluminum junction 
box, and connects via a short pigtail to the twist lock that engages 
the AC input to my car.


Of course, the PFC20 charger will take any voltage you throw at it, 
AC or DC, so the only thing to keep in mind is how many amps to set 
the charge rate at. Our utility's pedestals are fully capable of 
supporting the 20 amps the charger can pull. Elsewhere, I'd have to 
be careful that no one wasted their money installing a 16 amp EVSE.


The customer service representatives at the front counter are always 
disappointed if I come in to pay my bill and I'm not driving the EV.

Re: [EVDL] Charging adapter for J1772?

[Tom Keenan via EV]

I made an adapter to use J1772 level 2 when I had an older conversion car. The 
charger used an input of 120v. I found that most ‘commercial’ locations have 
220 volts at the plug, so I had to get a transformer that would put out 120v 
when supplied with 220v.

When plugged in to the rare Level 2 charging station with 240v (such as at a 
house) the transformer output would be about 160v, much higher than the charger 
could use. 

   I say this because if your charger expects 240v, and it is 
transformer-based, you may not be getting full charging voltage from the 
typical Level2 charging station. 

If it is OK with a wider range of voltage -around- 240v, than an adapter will 
probably work out.

Re: [EVDL] Charging adapter for J1772?

[Paul Compton via EV]

In theory, you can have a pair of EVSE outlets sharing the same feed,
so each one can supply 3Kw, but if both are in use then that capacity
has to be shared.

The one issue I have with those is that it doesn't prevent your charger from 
trying to draw MORE current than the EVSE allows.
As long as you have a 3.3KW (or less) charger, it will likely be fine - Unless 
plugged into a 120V 15A outlet where the EVSE is telling your charger to limit 
itself to 12A (about 1500W).  In which case you need a REALLY wimpy charger.

Re: [EVDL] Charging adapter for J1772?

[Paul Compton via EV]

I'm currently working on a Tuktuk conversion. It's basically a repeat
of one built by Saietta, but with my standards of packaging, neatness
and extra safety.

We're using an AVC2 module;
http://modularevpower.com/Active_Vehicle_Side_Control_development.htm

They're mostly only sold via ebay and we had to ask for a refund after
we got no response from the seller. They are most likely an individual
and may for instance have had a family emergency, but it was somewhat
inconvenient. Happily, I spotted that EV West stock them and we were
able to get one that way.

Ultimately, I'm going to have to design my own as shipping and import
duties make it quite expensive.

Re: [EVDL] Charging adapter for J1772?

[Michael A. Radtke via EV]

Tom,

I've been using that J1772 adapter box on my 1979 Jet ElectraVan for
years.  It works as expected.  I went that route because the parts cost
nearly equalled the unit price for the adapter and it was already
debugged and working.  

I elected to build my own EVSE for my I-MiEV because there was some
cost savings and I had some constraints that weren't effectively
addressed by commercial units.  However, that's a different story.

Mike

Re: [EVDL] Charging adapter for J1772?

[Jay Summet via EV]

Not an adapter, but my J1772 input solution:

When I upgraded to Lithium batteries I also upgraded my charger to a 
pair of TSM2500's from Thunderstruck motors and their EVCC (EV Charge 
Controller).


I bought a kit with the chargers & controller (but re-used the Nissan 
Leaf J1772 inlet from the salvage Nissan Leaf I purchased to get the 
lithium batteries).


The EVCC basically connects between a J1772 inlet and (canbus enabled) 
chargers and handles the pilot signal decoding, drive away protection, 
BMS integration, etc...

Re: [EVDL] Charging adapter for J1772?

[Kevin Lieberman via EV]

 I am currently making my own with this EV 
Simulator:https://www.tindie.com/products/nsayer/evse-tester/

It will just "fake" the EVSE into starting the current flow, and I can put 
whatever outlet i want on it.  The issue I can see is I won't know if its 110v 
or 220v, but there are ways around this.
