Hey everyone.

I have been charging my 2018 plug-in hybrid at the only ChargePoint at my job. The first two weeks I had almost no problems. Sometime it would stop but I would just reconnect it and it would usually complete the charge in about 2 hours. That all changed when I transitioned to third shift.

I plug in the car and I get the usual green solid light with the ChargePoint and Hondalink APP both confirming the connection. In about 5-10 min maybe less the Hondalink APP indicates the car has stopped charging. Reconnect it, solid green light, app confirms, minutes later stopped charging. Occasionally, my car will have the error message "Plug-in Charging system problem. Range Limited". Car still charges fine at a level 1 charger at home. I took it to the Honda dealership and they found code that states "Battery charger input voltage too high". They tell me the charge station is outputting too much energy and trips the battery's safety kill switch and it stops. They told me there is nothing they can do about the limit other than an update. However the update would cause double charge times (4 hours lvl 2; 24 hours lvl 1).

I have been tracking the charging output and notice the Honda always gives the error at 7.0kWh. I put a complaint with ChargePoint, but I am not hopeful. :(

Does anyone have similar issue?

Sounds like the "240V AC" feed is out of spec on the high side.

Anyone know if the clarity usually stops at 7kwh? Seems as a slow rate
Actually 7kWh is not a rate. It’s a quantity. It’s equivalent to 7kW of charge lasting for an hour. But the car is what controls the rate of charge. The “charger” is not really a charger. It’s a smart voltage source. When you first plug the EVSE into the car it tells the car what its maximum capabilities are. It is then up to the car to decide how much energy to take. So as EV Nerd mentioned, about the only thing that could be wrong with the EVSE is that the voltage could be higher than 240V but I doubt that is the case. I would definitely not allow Honda to “update” the car to double the charge time.

Have you experimented with plugging the car into a different level 2 EVSE at night to see if the problem is isolated to just one EVSE? If you’re using the same EVSE that worked during the day I might be inclined to think there may be some noise or surges or fluctuations on the line that could be caused by some other equipment that is operating at night at the same time.

The Clarity PHEV's onboard charger is rated at 6.6 KWh acceptance.

When I first got my Clarity two and a half years ago there were a few owners reporting problems with certain chargers. The typical symptom was that it would start charging, but stop charging after fifteen minutes or so. An example I remember is someone who had two charging stations available at work, one of them worked fine with their Clarity, the other one had the problem. They could charge at home with no problem. Clearly the problem seemed to be with that one charging station. However they noticed that no other cars seemed to have a problem with that charging station, only their Clarity. This was what service bulletin (and software update) 18-097 addressed. I seem to remember that most people who had this update applied, it fixed the problem. I think I remember one person who it didn't fix it. But either way I don't remember hearing anyone say that after the update now their charging times are slow. Where that idea seems to come from is what the bulletin says:

"Once the update is completed, the vehicle may take up to one and a half times longer to fully charge. This depends on the power quality in the area, which will affect the charging rate."

I think some people only remember the first sentence, and assume that after installing the update charging will now take nearly twice as long, all the time. But it said "up to" one and half times longer. And it seems to indicate that you would only experience slower charging at stations that have fluctuating power source. And even those stations it may not be slow all the time, assuming the power fluctuations are sporadic, it might just slow down briefly and you may not even notice it, whereas without the update even a momentary power fluctuation will cause charging to stop.

I understand the concern about installing the update, and it's not my car so I'm not giving advice, I'm just pointing out my observations. I have also noticed that I don't hear about this problem very often anymore, which seems to imply that people with the problem had the 18-097 update installed and that fixed it. And presumably newer models of Clarity have this update applied already, although we don't really know that for sure. I just know the problem seems rare now, at least from what I read in forums like this.

The other thing I remember is that unlike the other service bulletins for 2018, people reported that the 18-097 update does not automatically appear on the dealer's screen when they enter your VIN number, thus 18-097 unlike other updates does not get automatically applied to everyone who takes their 2018 car in for service. Someone has to specifically say they are having problems at some charging stations. Even then the dealer may not be aware of the bulletin so people sometimes had to tell them to look up 18-097 on their computer, and when they did and they saw what it was for they installed the update. I remember one person had a 2019 with the problem, and there was a question whether the dealer would be willing to apply an update that says it's for 2018 models. I don't think I heard what happened on that one, whether the dealer installed the update or not.

Thank you, those posts were very informative. Going forward I will test out if this occurs at another charge station around the same time. After reading the 18-097 bulletin board I am interested to know if people are indeed experiencing longer than normal charge time outside of fluctuating charge stations. Where I live, Honda Clarity's are not too common and indeed this error message was the first time my Honda associate had seen it. I need to get more information about 18-097.

Honda Claritys aren't too common anywhere. From 2017-2021, Honda only sold a total of 40,000 units in the USA. That's for all three models (FCEV, BEV, PHEV) together.
