I've been having intermittent charging problems for quite some time. When plugged the van doesn't start charging, I have to unplug it and plug it back in to get the charging started. It happened on all kinds of chargers, so I know that the problem is in the van. It may happen daily or not happen for a couple of weeks. Of course I could never show it to the dealer.
This month another problem popped up. I can start charging, it works, but in a couple of minutes it stops. When I open the driver's door, the instrument panel says "waiting to charge on the schedule". When I close the door the charging resumes. Needless to say, the schedule is not enabled. Unplugging and plugging back also resumes the charging.

The van is almost year and a half old. Why would a software bug show up just now?
Any tips on how to make the dealer take this intermittent problem seriously? This new problem is worse than the original one because it stops charging after I leave thinking that the van is charging only to find it with a half or less charge.

Switch to DST? I know, it’s a long shot...

Actually a good suggestion. The software driving the car is complex and the time change can have far reaching consequences. But I saw this problem right before the switch to DST.
Wondering if there’s a way to do a reset on the UConnect and/or any other pertinent system. Pull a fuse and then re-install? Might be worth a try.

That could help. Although I had my 12V battery replaced in February, and this glitch appeared shortly thereafter.
Some shops keep power on the battery cables while swapping batteries so as to not cause certain electronic things to lose their settings (like pre-programmed stations on your car radio). Do you think they might have done that with yours?

The mechanic never mentioned it, so who knows. The van doesn't lose the radio presets, and the clock is synced to GPS, so it is hard to tell. I'll try disconnecting the battery, maybe it will help.

Am I the only one with the similar charging problems? Software bugs are seldom limited to single units. I'm starting to think that my van is cursed.

Sounds to me like it is an intermittent bad contact in the charging port, not a bug. The "waiting to charge on schedule" message can be triggered either by the van's own scheduling or by the external EVSE's scheduling. In my case, with a ChargePoint EVSE the scheduling occurs on the EVSE and if you plug in during the EVSE's non-scheduled hours the van knows that it has to be patient and wait for the EVSE to supply power and does not pop up with a message to check the external charging system. You might try using a canned air duster to blow air down the holes of the charging port -- maybe it will be able to blow some dirt out. Or you could try a q-tip with some alcohol. I think that would be safe as long as the van is off and the high voltage contactors are not closed. To be absolutely certain of that you could lift the carpet under the second row and pull the main disconnect that is under the floor.

Thanks for the suggestion, but it doesn't match what I see. If the EVSE is set to charge at a schedule, the van doesn't see that it is plugged at all. It certainly doesn't pop the "waiting to charge on schedule" message, it has no way of knowing what is going on in the EVSE.
When the van is plugged in, but not charging, the EVSE shows status as "connected", so the van interacts with the pilot signal and the connection is good. The bad connection theory also doesn't explain why the charging starts after the driver's door is opened and closed.

Hi stop-eject,
We understand how frustrating this charging concern must be. Have you had a formal diagnosis at your local dealership? Send us a private message with additional details so our team can learn more about your situation.

Jenn,
Thanks for reaching out. I mentioned the problem to the dealer during my last visit. They couldn't reproduce it, which is unsurprising- one of the problems may show up maybe 1 time out of 10. I understand that they can't effectively troubleshoot a problem they don't see. FCA should take an action, just like they did with the infamous engine stalling disaster that also was highly intermittent and triggered no codes. I'm trying to record videos of the problems to demonstrate that they are not user errors, what else should I do?



That problem happened again today. I came from work, plugged in and waited for the charge to start. Hour later I needed to drive my son to an activity. He was few steps ahead from me, and was getting into the middle row when the van came into my view. I immediately noted that only the 1st and 5th charging LEDs were blinking, indicating the "Waiting for schedule" status. My son closed the sliding door and the charging started. So it seems that returning to the normal operation can be done by opening and closing any door, not just driver's.
I got in, the charge was 18% instead of the expected 50% and I decided to take a different car.

Hi stop-eject,
Thank you for providing this additional insight. Can you please send us a private message with the date of your last appointment with your dealership? From there, I can better explore any available avenues of assistance.

The two outside LEDs blinking is an indication of an external charging fault. The "waiting for schedule" indication is a slow progression of the lights, 1, 2, 3, 4 and 5. I think that both the van and the EVSE thought they were connected but the car wasn't receiving power on the main charging pins, thus triggering a "check external charging station" indication. I still think it is a bad contact inside the charging port. of the van.

Thank you, I'll recheck it next time when it will happen. Yesterday I only coughs a glimpse of the LEd before the van started to charge, and could be wrong about the sequence.
How the bad contact theory explains that the charging starts after a door is opened and closed? Some slight movement of the van? I don't think so, but next time I will wiggle the plug instead of unplugging and plugging it back.

What is the likelihood this is related to what I've read is the unorthodox way FCA configured the PacHy's charger to communicate with the EVSE?

For example, there is a problem using the adapter made to allow a standard J-1772 type plug to be used with the Tesla HPWC (not the Supercharger). Evidently, only the PacHy 'talks' to the EVSE in a different manner than all other plug-in EVs and it will confuse the Tesla unit. In effect, the two units both try to initiate charging, and neither receives the correct signal.

I still hasn't captured a good video of the problem, the one I have shows that the lights are going 1,2,3,4,5 and the dashboard says "waiting for schedule", not "charging error".

I have read about this incompatibility too but I would like specifics on why it exists. As far as I can tell, the PacHy adheres correctly to the protocol for communication between the EVSE and the car. I bought a used, non-working EVSE off of eBay and did some troubleshooting with an oscilloscope. To make a long story short, the problem involved a resistor that was in the handle of the J1772 plug on the proximity line. But I scoped the pilot line and saw the signal go theough all of the steps required to initiated a charging sequence just as documented by several sources I found on the internet. So it’s puzzling to me why the Tesla EVSE would not work with the PacHy but would work with most other vehicles. If I knew the details of this incompatibility I could probably design a way to make the Tesla adapter work.

The website for the Tesla adapter says it will most likely work with the PacHy, but there are caveats that don't exist for any other EVs. I don't recall exactly, but it was something like it will only work up to a certain amperage on the PacHy. The reason for it was then explained, and that's where I learned about the different way the PacHy's charger was configured.

But, yeah, it's puzzling how no other EVs have an issue with the Tesla adapter. I would have thought they all work in essentially the same manner but, again, maybe as with FORM, it's a case of FCA making a situation more complicated than it needs to be.

Considering the relatively rare availability of the Tesla HPWC (High Power Wall Charger), it seemed like kind of a moot point, anyway.
