UPDATE: UPDATE AGAIN: Continuation of a charging issue

[TRP]

Posted in the past about this. Grizzl-E dumb charger at 40amps on a 14-50 circuit. If car is down to say 30% it would start at scheduled time but stop in the mid 70s%. Figured it was a grid issue as it seemed to happen during a storm mostly. So I tried the ford charger that came with the car and it worked fine, no storm that night. So I flipped the dip switches on the Grizzl-E to 32 and tried again. Came home at about 30%, it was a hot night and we traveled 100 miles and parked in the sun all day, then drove the 100 miles home and plugged in the car. Schedule is 9pm-9am. It was after 9pm when I plugged in, charging started and I went to bed. It stoped at 76%.

Yesterday wife drove to the airport and parked and flew to east coast and then back same day. Picked up car and drove it home. Arrived with 19% remaining. Plugged in and charging started on schedule. Little rain over night, no storm. Car stoped at 60% charge.

Common denominator, to me, seems to be that the car was hot when plugged in. Could it be that heat is preventing it from completing the charge to 90% as scheduled?

No other issues with it and if I force it to finish charging it will with no complaints.

As far as I know all updates and TSBs have been completed and I really don't want to drop off at dealer until/unless I know what is wrong. Maybe it's working as designed ?‍

Just to be clear, it's stopping at the percentages you report prior to 9 am?

That's correct.

I contacted Grizzl-E and it "may" be an issue with their EVSE. I'm trying to determine if that's the case or perhaps it's just that the charge session was started while the car was hot and that is causing the car to stop the session before it's complete.

One more clarification question: does it charge to 90% as scheduled when the car is cool at the start of charging?

It seems to, but to further clarify this.............It only seems to happen when it's below a certain percentage point. If I plug in at 80% it will charge with no issues. If it's below 50% that seems to be when the issue pops up.

My routine has been to plug the car in when not in use with the charge schedule set for 9pm-9am. It may only need a couple percent each night, for example. If it's above 80% I don't usually plug in and I only push it to 100% if we are going somewhere first thing in the morning. We are in a rural area and even a trip to Knoxville is 75 miles 1 way, so that's the only time I charge to 100% since there aren't many charge options around here except for home.

So if the battery is hot, it will spend time cooling it before the charging starts. This shouldn't take more than an hour though, and at 32 amps the car should almost fully charge from empty in a 12 hour period. Any chance your garage is staying over 100ºF for prolonged periods at night? Maybe leave a recording thermometer out there to see what the max temp gets to overnight.

Use the Ford charger for a week and see what happens. Then switch back to Grizzl-E set to 32A. If the problems start again then it's the Grizzl-E.

If you're handy with electrical, you might try to measure the voltage while it's charging to make sure your circuit is in good shape.

Car is parked outside all the time, no garage.

I'll switch back to the Ford charger for a while. I sent a tech ticket to Grizzl-E and am waiting for a tech to get back to me but I'm leaning towards it being a Grizzl-E problem.

Reason I say that is because we took a recent trip to Baltimore. 575 miles and 2 DCFC stops on the way. Arrived with 30% battery and plugged into a 50a outlet with the Ford charger and it charged to 100% with no issues overnight.

Contacted Grizzl-e and just received an email that they looked into it and based on serial number are sending a replacement unit to me along with a shipping label to return the unit I have now.

Talk about fast customer service. Hopefully this corrects the issue.

In the mean time I will be using the unit provided by Ford.

Several of us have had a similar issue with our Grizzlies and have received similar fast replacement. My replacement has had only one need to reboot in the 3 months since replacement.

Well that's good news I guess. Great that their customer service is good, but bad that there's a need to replace many units.

I'm going to call them first thing tomorrow and see if I can pay the difference and get a smart unit shipped out instead of the dummy one.

 

[TRP]

OK, they are going to ship me a new smart charger and I'll pay the difference in price.

I asked about an app and was told that their app was not ready yet but they had a portal in the mean time.

I understand that this unit will work with other apps. What are you using?

Recieved the replacement EVSE from Grizzl-E. Upgraded to the smart edition. Only had time to plug it in and do a short charge on the care before our recent trip. It charged up just fine. Have not connected it to our wifi yet.

Returned last night with 14% remaining, plugged in and went to bed. Car charged up to 90% just like it was supposed to. So thankfully it was the EVSE and not the car causing my issue and it seems to be working fine now.

I'll try and set up the wifi with it later but it works fine without it, just no smart features yet.
