No charge with J1772 adapter

edited November -1 in Model S
Hello everyone! New CPO owner with a question about the J1772 adapter. More specifically, i am having issues using the charging stations at work. they are made by GE, 4 pedestals with 8 plugs to use. The issue i am having...the car says its plugged in to the charger and waiting on the charger to start. The chargers say its plugged in and waiting on the car...has anyone come across this problem/issue? Any thoughts? I took a couple pics but i guess we can’t post those on this forum.

Thanks for any help!

    Does your UMC work on a NEMA 14-50. Does your car supercharge ok. If so it is likely a faulty J1772 adaptor or some issue with the charging station itself. Is this a free charger or is a fee required? Have other Tesla's used it successfully.

    I have two J1772 EVSEs (they are not chargers, the charger is in the car) in my garage that work just fine with my adapter.

    Post your pictures on the internet (dropbox etc.) and then put the URL to the picture in your post.

    When I have trouble with CHAdeMO or J1772 start ups, I'll try to connect in different ways, i.e., put the adapter in first, then connect. Some connections seem to fail when they connect to an adapter and there's no immediate handshake.

    Exactly what JayInJapan said - pay attention to the order you plug things in. Make sure the adapter is pushed all the way on the J1772 handle (the clip actually clips). Try plugging this into the car and then starting the EVSE. If that doesn't work, try starting the EVSE and then plug in the car.

    You could also try limiting the amperage inside the car at that location (on the big screen, when you plug in there will be arrows to limit the amps drawn).

    The station may require a card to start it.

    ^^^ Agree with above, the first time I tried the J1772 I didn't push hard enough putting the adaptor onto the power cord. Also good advice about the card. You should get a chargepoint card just to have in your car in case. Not sure if your work charger is Chargepoint, but wanted to throw that out there. Good luck on your next attempt.

    It sounds like the station isn't really activated/started yet. Is there some kind of RFID card system or membership network for them?
  • edited June 2017
    Agree, sounds like the stations are either not activated or require additional steps to activate charging (membership). Be it a free or pay charger, many of them require you interface via phone or app. And some may require you to register (even if its free).

    I want to thank everybody for their feedback! I wanted to add a little additional information about what’s going on.

    The chargers are installed at my office, 4 pedestals with 8 total plugs (J1772) made by GE. They are currently being used by other employees. There are no ID cards or pins codes, they are simply plug in and go. I think i am the first Tesla at my building so i couldn't say if any other Tesla’s have attempted.

    I have used my J1772 & Chademo adapters at my local shopping center, whole foods etc. with no issues to date. Supercharger is good also. I have only had issues with the chargers at my office. The car and charger recognize that a connection has been made but it seems like the signal to begin charging is not being sent/received...

    I made a call to the company facilities group who inspected the chargers and recommended i contact Tesla.

    Could be some nuance in the J1772 protocol implementation with the EVSE or Tesla. Will be difficult to know which without detail knowledge of the protocol and a sniffer.

    try looking on your charging screen and check the following:
    is the timer on for that location? Problaby wont set itself, as default is "no timer"

    Would it help to turn down the amps? Mine will adjust itself to the output of the charger, but I've read that some Tesla owners may have had to manually adjust this.

    OK, problem solved - it is an issue with your work EVSE. It is faulty. Tesla is super sensitive to electrical problems, it won't charge if it senses even a minor problem. Other cars will happily charge even if there is a problem. Until they fix your work stations, guess you can't charge there.

    @bburnham1141 - no one has asked what color the charge port is. When I plug in it turns green and starts flashing. If there is a problem it is supposed to turn red. Other colors are white and blue, and there may be more. What do you see when you plug in? Anything except green would indicate a problem. I'd expect to see either red or no color, but I don't know. I have never had a problem charging my car. The color should be seen in the ring around the port where you plug into the car behind the rear driver's side reflector.

    OP, did you try any of the suggestions we posted?
  • edited November -1
    @bburnham, OK, I'll second these recommendations:

    From @UnshodBob, check what color your charge port light is.

    From @5thumbs, check to see if your car is set for scheduled charging, where it might be waiting for 1AM or something to begin a charging session.

    OK I’ve been away for a few days. I will be meeting the facility folks at the chargers later this afternoon; I’ll try to get additional details about the port color and time of day charging settings. I also reached out to Tesla this morning. Gentleman said he was going to pull vehicle logs to see if any error codes were generated....updates to follow!

    OK update time...

    1. I verified that time of day / scheduled charging is not enabled.
    2. I manually lowered the amps to 25 just to be sure that wasn’t the issue, no luck there.
    3. The charging port is light blue and turns a darker blue when the adapter/charger is plugged in. Same message from the charger "Connected. Waiting for Vehicle..." The car console screen shows plugged in and "Ready to Charge / Check Charger Power" I took pictures this morning, ill try to post them.
    4. I haven’t heard back from Tesla but coincidently i was pushed a software update last night...but no luck there. Still not working...

    I thought about checking for a gasket that i have read a few posts about....but haven’t gotten around to that yet.

    Any other thoughts?

    Thanks again!

    @bburnham1141 - thanks for the update. Many people don't bother. Continued good luck on a fix.

    Blue ring is an indication there is a scheduled time to charge. Make sure the car is set to charge without a schedule time

    Have you tried connecting things in different orders? Put the adapter in first, then hook up the J1772 connector. Watch the charging station's output. The info it tells you may have clues.

    Ok so i just got back from the car and....SUCCESS!! I had read in one of the earlier comments about the order of plugging the adapter into the car then the charger into the adapter/car. I really didn't think this would be the issue becuase i use the J1772 adapter at other chargers without any problems....however i read @JayInJapan's comment and thought...heck why not just give it a shot you've got nothing to loose and SUCCESS! i am now charging a work. I can't begin to understand the issue that was holding me up but..the problem appears to have been resolved.

    Thanks to everyone who commented and gave suggestions. I'm new to the Tesla world and it def helped to have somewhere to ask some questions.

    Just as I thought. I have more experience with J1772 and CHAdeMO than Supercharging.

    Part of the J1772 specification concerns what happens if there is a power failure while charging is in progress. In that case the J1772 EVSE is required to do a random restart so that all J1772 EVSEs don't try to come online at the same time which would present a huge instantaneous load to the power company. I have two J1772 EVSEs in my garage. I must apply power to the EVSEs before I connect to the car. If I don't, the start of charging can be delayed up to a half-hour I think. I can't measure the maximum because it's a random delay. The rule in my garage is to apply power to the EVSE first and then connect it to the car.

    Glad you got it fixed. And JayInJapan was persistent about reminding you to try something.

    It had to do with the work charger's ability to communicate with the car. When you put the adapter on the work J1772 cable end, the work charger immediately tried to communicate with the connected vehicle and failed because it was connected to an adapter and not the car. The work charger immediately went into shutdown due to what it perceived as a faulty communication link. But when you put the adapter on the car and then connected the J1772 cable to the car it worked because the work charger was able to communicate immediately upon connection.

    This makes total sense to anybody who has any experience with networking equipment.
