not charging

welcome!

is this your first charge attempt, or has it been working up until now?

first, make sure you don't have any scheduled charging.

then look inside the charging port to make sure there is nothing blocking the plug.

third, the click sound is simply the lock snapping over the hasp. is it going far enough in to complete the procedure?

if yes, do you have power at the brick?

 

When you say "no green light flashing", do you mean the green charging indicator located inside of the charge port? If so does it light up at all? How about the light on the CCID (charging circuit interrupting device, aka "brick") lights? Is the Power indicator ON? How about the error warning indicator?

 

Sometimes the rubber o-ring in the bottom of plug receptacle on the prime is twisted or bunched up so the charging plug can’t fully be inserted to make the click sound and start charging. If I remember correctly Toyota (or was it just PriusChat members) said to take the o-ring out with no ill effects for the PiP. Could be the same problme on your Prime. Shine a light in where the charging plug goes in and tell us what you see.

That lack of a click is your clue. Make sure the handle gets seated all the way. When that happens, the latch on the EVSE handle should have snapped down over the catch on the charging port. If that doesn't happen, something is interfering either with the handle going all the way home or the latch dropping all the way down and the car will not charge.

Due to manufacturing tolerances, some handles can be more forgiving than others of debris behind the catch in the charging port.

If the latch is snapping all the way into place then I'd suspect it's the contact inside the handle that tells the EVSE and the car that the handle is properly connected to the car. You could open up the handle (unplugged from wall and car, of course) and test that limit switch. Here's a thread that shows what the handle looks like inside. It also shows the resistance you should get in open and closed states while installed. Repair J1772 | PriusChat

 

Sound like it's time to visit a dealer to get a new L1 EVSE under warranty.

 

Hummm, so did the dealer tried different OEM charger for PRIME on your car to see if it is really the charge port problem? It is strange that you can use ChargePoint charger without problem though. I have no idea how complicated the fix is, but it should be taken care of under warranty for sure. Let us know how it goes with the dealer.

 

I agree with @Salamander_King. Since the ChargePoint EVSE works, the likely culprit is the EVSE cable that came with the car. Just have them try another one and see what happens. If they don't have one, there are no quantum mechanics involved in figuring out what's wrong with the one you have. This should be easy.

 

That seems to be conclusive, that there is something wrong with the charge port, but still strange that why then ChargePoint EVSE works on your port. In any case, it is taken care of under warranty. I hope it gets resolved quickly. Please keep us posted as to the outcome of the repair made. Good luck.

 

Very interesting!! Bottom line seems to be that the dealer needs to figure out how to make this right. Based on those tests, it sure does seem like it's the charging port. But very mysterious.

 

I can see this post is a bit old now, but I'm curious if you ever resolved this issue? I have the same issue - I can charge on multiple charge stations (ChargePoint) at work, but my home charger (the one that came with my 2017 Prius Prime) no longer works. It plugs into the car smoothly as always, but now there is no click and the Prius doesn't recognize that I've plugged a charger in. My charger doesn't have a gasket (one common Prius charger problem), and there is no debris or anything mechanically obvious that would prevent my charger from fully mating with the car. Before I go the dealer, I was curious to find out if the mystery was ever solved.
Thanks!

 

The OP of this thread never reported back to us what happened to his car. He has not logged on to PC over 50 weeks. It is safe to assume he is gone.

 

My guess, and that's all it is, is that the proximity pilot circuit is defective in your EVSE plug, possibly because the switch on the plug has failed. The symptom you are experiencing is what will happen if you plug a (working) EVSE in while holding down on the switch; only when you release the switch will the plug lock into the socket with an audible click.

If that is in fact the problem, I shouldn't imagine it would be all that hard to repair if you can find someone willing to do so.

 

I think @Jon Bloom hit the mark. It must have to do with that little switch. I've had 2 or 3 of the handles apart and they are pretty simple. If you aren't getting a click it might be that the lever on top that you release with the button on top isn't dropping into place and closing that little switch. The click comes from the spring snapping the lever into position when it clears the back end of the ramp on top of the charging port. Or the switch might be bad. And, since the wires from the switch are very small, it's not inconceivable that one of them might have broken, but that's unlikely.

Not to worry about the O-ring. That was only on the early PiPs. AFAIK, they removed it for good starting in 2013.

The picture below is from a Czech website. It shows some sort of a relay at left, near the end of the cable. I don't think that is there in the Toyota EVSE, but it's otherwise like ours other than wire colors. It's not super clear in this picture, but there's a little metal switch lever at the end of the arrow leading from "if this." I haven't heard of it breaking off, but it would cause your problem if it did, so it's worth checking while you have the handle opened up.

The most likely failures would be something behind the ramp preventing the lever from dropping down and closing the switch in the circle below or the switch itself.

 

As I think about this some more, a broken wire actually seems like the more likely cause. The OP isn't having trouble unlocking the connector; he is having trouble getting it to lock. That suggests that either the switch is permanently closed, which strikes me as a somewhat unusual albeit not unknown failure mode for a switch, or the circuit is not connected at all, which suggests a broken wire. The receiver is supposed to detect the plug by sensing a particular resistance in the proximity pilot circuit. The two conditions which should cause the receiver to unlatch (or not latch in the first place) are a lower resistance that appears when the switch is depressed, or an infinite resistance because the plug isn't connected. It's hard to tell from the photo where the resistors are. Quite possibly they are in the switch module itself. If so, and if all of the wires are intact, replacing the switch module should solve the problem.

Of course, my first instinct is to suspect the connector itself, but the OP says he inspected that and didn't see anything awry.

Edited to say: I guess it is possible that something sticky got into the plug assembly and is holding the switch closed mechanically. So don't use the plug while you are eating your morning waffles and syrup!
