Car-net and delayed charging

[miimura]

My e-Golf with the TSB applied is consistently running over the departure time when charging from the provided 120V charging cord. The first night the estimated charging time was 6h 40m and it was going to finish about 8:00am when set for a 7:00am departure time. I unplugged it early because we had to leave. The second night it was forecast to take 3h 0m to charge and actually finished at 7:15. I will have to try it on our 240V station to see if does a better job of hitting the departure time.

Is that because it starts later (based on faulty calculation) or just charges slower than usual?

Well, let's see. My SmartMeter data for Thursday was just posted. When I plugged in the car I manually had it start charging, then I looked at the dashboard. It said it needed 6:40. Then I pushed the timer button again.
The data shows that it actually started at 1:00am. So, it started late because it should have been 7:00 - 6:40 = 12:20. Then, it wasn't even done 6:40 after it started because I unplugged it at 7:40 and it still said it had 20 minutes remaining.

So, IMHO, it's both. It started late, even according to its own number, and it charged slower than what it said.

Here's the chart from the PG&E web site. You can see the 1:00-1:14 bar is the same height as the subsequent ones, so it likely started very close to 1:00. The bars in the chart are kWh accumulated in 15 minute intervals. The tall peak is my RAV4 EV charging at 240V 40A. So, my max draw with both cars charging was 2.77*4=11.08kW including a background overnight draw for the rest of the house of about 650-750W. Thursday was a rainy day, so the solar generation was spotty and not very strong.

In any case, I will charge the e-Golf on the Leviton EVSE this weekend and see how it does on hitting the departure time.

Had TSB applied but was still unable to get iPhone app to upload any changes to car.
Rebooted car two days later and now it works.

Did a delayed charge last night and it completed 3mins before scheduled departure.

Several of you have mentioned "rebooting" the car. Is that simply detaching and re-attaching the 12 volt battery, or is it something else?

What EVSE did you use for this test? If you know the Volts and Amps delivered by it, that would be good to know too.

Yes, see this post for more details

I am happy to report that delayed charging finishes on time when connected to my 240V Leviton charging station. It starts late and runs a little long on the provided 120V charging cord. The departure time was set for 6:00 am and I figure it finished at about 5:53.

Got the TSB applied to my e-Golf and Delayed charging worked smoothly last night. Very happy about it worked and I didn't have to take it in again like some folks on here have reported.

I had bulletin 93-15-01 applied May 12th and delayed charging is now working very consistently.
The only item to watch out for is the off-peak times, they need to be set to East Coast time.

Finally, I have confidence that the car will be charged when i go to work in the morning.

I dealt with VW corporate and there customer service was extremely good.

Hi,

I'm an enthusiastic e-golf owner since february 2015 living in Belgium, Europe.
Finally I find out that I'm not the only one having problems with delayed charging !
In the morning I'm never sure he's charged up to the preset level, so when I have a large trip to do I disable the e-manager of my care the evening before. According to me it is indepent of the car-net app on my iphone.

I sent a detailed log to my dealer, he is taking my complaint very seriously. So far no answer yet...
So the problem is also appearing in Europe!

Note: in Belgium the car is only available since 12/2014 so there is not a lot of experience by now.

I 'm reading your comments with a lot of interest !

I ran a test to see if delayed charging with the Maximum Battery Charge Level works. I have confirmed that it does. Here is how I have it set up.

Charging Locations:
1. Setup a location "Standard" with the following settings:
- Charging Enabled
- Max Current = 32A
- Max Charge Level = 100%
- Off-peak Power Inactive
- Heating/Ventilate Disabled

2. Setup a location "Reduced" with the following settings:
- Charging Enabled
- Max Current = 32A
- Max Charge Level = 90%
- Off-peak Power Inactive
- Heating/Ventilate Disabled

3. Set Departure Schedule 1 Enabled for "Every Time" Mon, Tue, Wed, Thu, Fri, Depart 6:00am, Charging Location "Reduced".
4. Set Departure Schedule 2 Enabled for "Every Time" Sat, Sun, Depart 8:00am, Charging Location "Standard".
5. Set Minimum battery charge level = 20%

With these settings, the car did properly delay and charge overnight to 90% as shown on the dashboard gauge. However, it ran very late charging from the provided 120V charge cord. It was set for 6:00am departure and didn't actually finish until about 7:15am. Also, the Charging screen in the app showed all 10 bars on the graphic instead of the 9 bars I would expect.

Thanks for the details and screenshots — they are helpful. Do you have any idea if I can expect this to work with a Clipper Creek L2 unit? I have a single profile set to charge to 100%, with a scheduled departure time of 6:00 AM, repeating daily. Off-peak charging is off, as is climate control. Minimum charge is set to 20%. With those settings, I've woken up disappointed every morning.

You're 3rd person on this forum i've heard of that can't get an L2 Clipper Creek working with delayed charge. In fact, I don't think i've seen a post yet of a successful delayed charged with clipper creek L2.

For reference, other two had HCS-40 hardwire and other had the HCS-60. Perhaps they can chime in if they're reading this.

Yes, Unbeliever was the first to report it with his HCS-40. I have the HCS-60 and also cannot use delayed charging. cove3, and madscot have L2 Clipper Creek chargers but I'm uncertain if they have been able to use delayed charging. I think we've all had the latest TSB applied.

I have a CC HCS-40 hardwired, TSB 2040470 applied a week ago, performed reset through 12V battery disconnect after the TSB was applied.
All the above didn't help, it didn't perform timed charge at all! I deleted a custom charge profile, means only the Factory Profile is left and since then I am in contact with Car-Net customer support. They stated yesterday that they ran a network wide update last Wednesday June 17 which was supposed to fix the delayed charge issues.

I played around with the departure time last night and set it to 9pm at around 7:50pm. When I plugged in the charger, it started charging immediately, which it was supposed to do to make the departure time. Then I set the departure time back to 8am. This morning it started charging (which was an improvement) but it ran over the departure time. Also I am not sure if me requesting status updates through the web and phone application to see if it started charging actually triggered the charge start or if it would have started the charge automatically.
I am waiting to hear back from a Car-Net "specialist" today and will report back.

Madscot here,

my problem is with Carnet - not the clipper creek, or specifically I can't tell if I have a problem with Clippercreek or not because Carnet apps / website won't allow me the program delayed charging.

I was unable to set the schedule in the app and the web site before I had the TSB applied. It would fail at the point where it tried to send the schedule to the car. After the TSB (and possibly a CarNet router reboot in the car) everything just magically worked.

I would open a case with VW Customer Care and get their input for how to get it fixed.

Also, I'm having a really hard time understanding how the Clipper Creek L2 EVSEs can be unique in failing to charge. Like somebody said earlier, the logic board is the same in the CC L2 as the L1 that is provided with the car, because the provided one is designed by CC.

Thanks - I have a separate thread going for my issue - the case has been open since Jan 2015!

I agree.
