How To Repair Evse Plug

Folio 1 of eleven

1. Hullo everyone! I'one thousand new to the forum, equally I'm a new Clarity owner (Touring model), from Toronto, Ontario (Canada).

   We received our car on Feb. fifteen, and ix days later, I ran into a charging error when plugged into a 240V public charger. The light-green charging light on the car's plug-in port was blinking rapidly, and then would eventually go out. Charger did non show a fault (I tried multiple chargers in various locations to run across if this would be different, thinking, maybe it was a charger error).

   This happened on a Saturday, so I anxiously waited until Mon morning time to have the car to the Honda dealer. They hadn't seen this problem (auto's too new on the market place!). They did a "system reset", which basically ways they removed the negative terminal on the bombardment (under the hood, not the chief bombardment on the bottom of the motorcar) to restore factory defaults.

   The error went away, and they were able to charge normally. They release the machine to me and said "let us know if there are any more problems".

   Fast forrad iv days, and the error pops upwardly again! Both times, I was a 240V public charging station (nosotros don't have charging at habitation yet, every bit we live in a condo, and it'south an uphill boxing to get charging installed there).

   So, I take the machine back to the dealer, and they immediately become the Service Managing director to talk to me. It seems that later my initial report, Honda Canada contacted the dealer the next day, to let them know this is a known trouble.

   Honda's explanation:

   This not an mistake with the car. The car has a built-in protection mechanism in its software that trips if in that location is current fluctuation during charging. So if the current changes (even slightly, or momentarily) during the plug-in charge, the system shuts downwardly to protect itself, throws the error, and the error message must be reset.

   In other words, the power source must be "clean" (pure, uninterrupted, etc.). Honda recommends using Honda-installed 240V charging (ie. at dealerships).

   HAH! That's crazy!

   So, the Service Manager says, aye, that is crazy. No one tin charge at the dealerships on a consistent footing. It's not applied and that's not a solution.

   And then, Honda is now obviously working on a "software fix" which essentially will change/remove this shutdown feature, allowing "unclean" power to charge the auto. Not certain how it will work (how astringent can the fluctuation exist? will there nevertheless be some type of protection available?).

   Apparently this is not supposed to be an issue if you are charging on a standard 120V plug-in, using the supplied cable/charger device that came with the car.

   Timeline is Apr/May 2022 for the software update implementation, and probably will be done on a recall basis. I will be getting a call from my dealer, as I am the only ane who has reported this so far.

   Anyone else in this boat?

2. Welcome to the Clarity club of early on adopters. Deplorable to hear you've having this problem. I have charged virtually twenty times at a vey quondam public AeroVironment Charger and at my new ChargePoint at domicile with no errors.

   Has this been at the same charger or at different ones? Effort using a different charger to encounter if it's an unstable power delivery at that single charger and not a machine problem. Best wishes.

3. Hi. Cheers for the welcome!

   Yes, dissimilar chargers, and different locations. 2 of the Ikea chargers (different locations), and 2 public parking lots. All non-Chargepoint chargers. So far, just Chargepoint has been rock solid for me. Simply there aren't too many Chargepoint stations nearby my work or dwelling house (withal).

   I'chiliad hoping to get at least 120V charging in my condo soon, and so start the fight for a 240V charger (Chargepoint, if I tin can convince them!).

4. Bummer. Seems similar the problem is in the motorcar then. Good to know that you've got Honda to respond to the problem.
   Please proceed the states updated on the resolution. I volition exist interested to know if this is a problem/recollect for all of us or just Canadian models.

   I will try to go on from not bad jokes most Canadian electrons.

5. Apparently the trouble is widely reported in the U.s.a. (I think we simply have a couple hundred Claritys sold in Canada then far, so a statistically low hazard of the fault cropping up hither in substantial numbers).

6. Eva, I checked through the post on this forum and could not find any reports of owners having this problem. Where did you notice that this is being widely reported in the The states?

7. Honda Canada told the Service Managing director at my dealership. That is why a prepare is in progress (being developed in the United states of america).

8. Interesting. Please proceed the states updated.

9. Their explanation sounds fishy to me. I have charged at least a dozen public stations and accept never had a problem. I can't imagine that 4 completely split up stations would all accept poor quality ability.

   EV "chargers" (technically chosen EV Service Equipment) are not chargers, they are a fancy switch that turns on the ability when a motorcar has successfully negotiated connection, and turns off power when the motorcar tells it to or if they notice sure anomalies, like ground fault current. The path from power going into the EVSE and the cord going to the car is direct, in most EVSE it is a mechanical relay. My point is that the EVSE does not do any conditioning of the power - there is no transformer. The EVSE simply connects the 240V power leads directly to the cord going to the car.

   The pilot connection from your car may exist flaky. There are many written report of EV chargers (the part located in the car) with bad airplane pilot diodes, so they cannot properly negotiate for power. So the car will work with some chargers and not with others. I suspect in that location is a problem with your auto, so recommend keeping force per unit area on the dealer to resolve problem.

10. Eva, I am with Jim on this ane. If the Clarity were equally sensitive power fluctuations at an EVSE as your dealer suggests, many of the states would have been seeing this issue. Most of us here have used many public chargers without seeing this issue. What are the chances that information technology's just the EVSEs in Toronto that have "unclean power?" Very small compared to the chance that there is an issue with your vehicle. You should at least get a better explanation than "unclean" and toss it past the folks hither who know more about power than I exercise.

11. Thanks guys. Not bad to have back up on this frustrating outcome. Being a novice regarding EVs (though I've read a ton in the concluding few months), I'yard likely to believe anything reasonable they tell me....

    I will be pursuing this if it continues. In fact, I'yard going to become back to those "unclean" chargers, and see what happens. If they work consistently, or I get faults on chargers that until at present have been solid, I will truly doubtable my vehicle, and demand a pilot connection swap (under warranty, of course!). I can't go on spending days visiting the dealership (they're non open convenient hours with regards to my piece of work schedule). I'k losing vacation days!

    

12. To add together to my before post, the "many reports of charger issues" comment was not related to the Clarity. Virtually were Nissan Leafage, and most from 5+ years agone. The consensus seems to be that chargers (the device in the machine) and EVSE control circuitry have gotten more robust and interoperable since so, and there are non many incompatibility bug these days. A trouble ordinarily means either the car or EVSE are lacking.

13. I've charged a couple of times at public stations and take had no issues.

14. Endeavor turning on the parking restriction and closing all the automobile doors when charging.

    Information technology should non make whatsoever divergence but it has been reported that this sequence has been required for some public charging locations.

15. FYI hither is information that shows the connexion sequence between the auto and the charger or supply equipment once information technology is plugged in:

    Supply equipment detects PEV

    Supply equipment indicates to PEV readiness to supply energy

    PEV ventilation requirements are adamant

    Supply equipment current capacity provided to PEV

    PEV commands energy menses

    PEV and supply equipment continuously monitor continuity of safety ground

    Charge continues equally determined by PEV

    Charge may be interrupted by disconnecting the plug from the vehicle

16. This is a proficient source of info for the J1772 protocol. https://en.m.wikipedia.org/wiki/SAE_J1772

    It sounds similar the Door Open/Parking Brake matter must be on the car side but I accept personally not been able to replicate the issue to troubleshoot.

17. Thanks Alan. I had forgotten where I originally got that info.

    The dealer explanation seems far fetched to me, as well. For an EVSE to cause the machine to throw a mistake there would accept to exist a disquisitional organisation failure. If the handshake isn't there from the first, then there's no charge. However, loss of footing or a shaky footing (no, not the California type) could create the same consequence. And at a public charger, at that place'south no telling whether or non something's worn out, been tampered with, etc. But this likewise seems similar an outcome which would not affect the Clarity organisation - it just wouldn't shake hands with the EVSE.

    Also, for the arrangement to just shut itself down - not allowing further charges - also seems suspicious unless it's the auto's charging organisation that'south at fault. I go the "dingy power" argument, but it but doesn't wing with the sophistication of this equipment and the standards used. And in Us/Canada, we're really not seeing the kind of 'dirty' power that might cause bug. That makes me feel even more than like information technology is an in-machine charger problem. You might try using the supplied 120V EVSE for a few days and see what happens.

19. You are all wonderful sources of information. Thank you!I would LOVE to plug in using the 120V EVSE, but I currently don't accept access to a standard plug at home or at work. I'm parking at work in a public garage nearby that has 240V EVSEs for employ (free!), only no regular plugs.

    At dwelling, I alive in a condo, with no plugs anywhere in the underground parking (or outside). I'k starting the battle to get either a regular 120V plug installed in my spot, or 240V EVSE(s) installed for use for all owners. At the moment, I'chiliad the just EV owner in the building and the edifice is mostly older folks (less likely to consider an EV for future purchase). Nevertheless, this is the style of the time to come. I'm sure I'll wear them down eventually.

    No charging issues in the last 2 days using 240V EVSEs. I'll update as time goes on.....

20. Eva,

    I've used a dozen different public 240 L2 stations with my Clarity so far, and have never come across this 'charging arrangement problem' fault.

    FYI. However, I encountered a unlike charging issue with one specific public charging stations, where the station would report the car drawing little power and it would terminate charging (bold total charge) when the battery is nowhere close to being fully charged. Remote starts from the HondaLink app would restart charging, only oft stop shortly. That was a station part of the ChargePoint network and afterwards the station owner did some tune up piece of work on the charging stations information technology'southward working fine now.

    So far my take is that the Honda Clarity may be more than susceptible to station-side charging issues than other cars.

    BTW. How are yous clearing the fault code? Are you unplugging the battery neg-terminal or did you get an OBD-II browse tool and clear information technology from your telephone?
