Plug-in charging system problem

[Geor99]

Today was the second time I had this problem in my 6 months of ownership and charging from the same set of work chargers (Aerovironment 240V). Here is my unscientific observation based on a sample size of 2

1) Problem seems to happen when the other cars in the same bank of chargers are fully charged and not drawing power.
2) Also, my battery already had > 75% charge when I plugged in on both occasions

Lastly, I tried to get it to charge by using the hondalink app to
start charging - no luck
remote climate on - no luck
locate vehicle - this got the car to charge even though the dashboard still showed the power system error message.

I am not sure if it was just a coincidence or the "locate vehicle" is a temporary workaround. Anyone else experience this ?

I have been putting off getting the SB18-097 installed, but it is time I guess.

"Locate vehicle" always updates my honda app charging status to the current time, whereas often refreshing and/or closing then reopening the app only gives me data from the past- up to 40 minutes in the past.

Perhaps "locate vehicle" is the kick in the butt needed to wake up your Honda app to initiate charging

Yes locate vehicle does give me the exact charge % while the refresh only gives it in 15% increments.
I believe this is the intended behavior of the app.

I am curious about the "locate vehicle" being able to charge during these bouts of charging system failure (most likely due to power fluctuations in the charging station). I am interested to see if others can get this to work as well, but to be honest, I am leaning towards it being coincidental.

Guys,

I have had the charging error and difficulty in getting it to charge on the dual level 2 charger at work.

I went to the dealer to get the updates that I found on this forum. The dealer said that my car already has these updates applied. I bought the car on Oct 8th of this year. The VIN ends with 16,000, which I've learned is one of the newer batches of cars.

I point blank asked the service manager several times, even printing out the SB worksheets from Honda. He swears that the car already has these updates.

I was going to just live with this problem at work. I can get a charge 70% of the time.

The last 2 nights, I fully charged at home on 120V, when I realized that I'm getting a much fuller charge when it stops charging on 120v as opposed to 240V at work.

I can see more full charging bars on the vehicle energy screen, and it's 54 miles as opposed to 45 miles on the dashboard screen.

Any thoughts? I tried calling Honda but I got spun around for an hour.

Should I try another dealer? My dealer swears up and down that I have the current SBs, and he wouldn't reload it to appease me.

I can live with it, but I want these extra miles of capacity and I'd love to not have to constantly play with the phone at work to get it to charge so many times each day.

The dealer claims he can see my updates on the computer , but he couldnt print it for me as proof. I've tried the squeaky wheel gets the grease, but to no avail.

As if someone is playing a game with me, the day after this message, my car stopped charging. I do have a new theory.

Normally, I charge in the late afternoon as I work late. This is after every one else charges. Today I plugged in in the morning, and it stopped at 80%.

Could the dual charger give us issues when the other charger stops or starts? I had my coworker look at the time that he finished charging. It was within 3 minutes when mine stopped at only 80%.

I think it is mainly related to the voltage/power fluctuations from the EVSE. I have the exact opposite scenario - it fails to charge when there are very few cars charging from the same bank of EVSE's. See my post above.

Can you try the "locate vehicle" from Hondalink app and see if it resumes charging ?

 

[Geor99]

It resumed without needing to do that. I just clicked start charging.

Thank-you all for the valuable information in this forum. I too am a Honda Clarity owner in Canada; I love the car but have been burdened with L2 charging problems on and off. I engaged my dealer last year and had to make them aware of the problem. I gave them the 18-097 campaign number from the US. They contacted Honda Canada and confirmed the problem has been reported but they were still working on a fix. Have any other Canadian Clarity owners received a fix to the level 2 charging problem and if so can you provide me the campaign number.

It happened to me couple days ago. After Power System light is on, it won't take any charging on L2. I followed instruction on this thread by unplugging negative terminal from the battery that got rid of Power System error.
Called the dealer but fix is not yet available in
Canada. Wondering why taken that long!

That is bizarre. Why wouldn't the same fix work for the Canadian cars. Surely the software and charging system is not that different? I had so may L2 problems a year ago that all but disappeared after the fix. The good news is that the fix works fine.

I wonder if the difference created by the battery heater requires a different software fix.

Probably not a different fix but likely a different software package. If so for whatever reason they haven't gotten around to it yet, maybe because of the smaller number of Clarity sold in Canada thus less complaints about the issue.

I am on the same boat. It happened when I was charging my 2018 Clarity Canadian model using a public L2 charger. There are a series of 4 chargers and strangely, 3 out 4 would cause this charging problem. I have had 3-4 times of the issue from different chargers at different places. Every time after a trip the message cleared on its own. I could even charge the car up using the L1 cable that came with the vehicle right after I received the message. Sadly as the end of 2020 is approaching, Honda still doesn't have a solution for the problem. Wondering if they are actually working on the issue.
