Huge power draw while sleeping

[njb]

I have same problem. Left mine plugged in last night. Charged to 90% well before 10pm. 198KWh used this morning according to FordPass.

So, Reddit has some folks seeing what I’ve seen related to this post. I had a power bill that was well more than double I had ever seen a couple of months last year, and I finally saw this when I woke up. According to Reddit, some non-ford chargers (Grizzl-E is what I and one other victim used) were seeing massive energy draws with little to no charging. The fans/pumps stay on even though no charging is happening. I am in cold Colorado, but I also do not believe that the above power draw could be possible for cabin preconditioning over that period of time. That is over 10x my home usage just going to this charger for the time period.

I didn’t see a fix on Reddit, does anyone have an answer from Ford?

I don't have the slow charging problem but I see someone on that thread has also said that FordPass says it's drawing power the entire time it's plugged in but they have verified that it is actually not. I have a Tesla L2 charger so I no way to know if it's really drawing power except for the green light that bounces on it. My husband says that the green light was not on earlier this morning but it's on now because the car is preconditioning for a 12:30pm departure so I don't know. I also have not received 6.6.0 yet.

I guess I will find out when I get my bill if I have 24 hours of 7-9+kw draw or not. ComEd "realtime" online is a few days behind so I can check on there later this week to see if it registered that way.

I only linked it because one of the symptoms it addresses is excessive power consumption. I thought it may be helpful.

I have read that thread and my understanding is that the service bulletin does not address my issue.

One user in that thread had the same issue as me (huge energy showing) but his charger app shows correctly.

I don’t have an app for my charger, but have noticed a massive increase in power bills so it makes me suspect it actually is somehow pushing energy somewhere (heating the battery??)…but I have no way of seeing directly if the charger is actually outputting that much.

I’m not sure how you came to the conclusion that this TSB doesn’t address your issue, because your last paragraph describes the symptoms it addresses exactly.
If I were you, I’d have the dealer apply that TSB. Nothing to lose.

 

[Luda07]

what is the temperature where you are charging ?

if <50F, and you are on powerup 6.x, you could have the 'bad' update that is spending energy pre-heating your battery even when L1 or L2 charging.

I believe there is a TSB out to fix this finally, but I dunno if it is being delivered OTA.

It has been -12 the past few days! I have read that TSB but maybe misread it…I have an appt with ford to check it out and looked up a code from Reddit that seemed applicable to my car (separate issue but maybe same bulletin) not charging at 40A:

From Reddit
POE5F.
Followed PPT L. L1: No, L2: No, L3: Yes, L4: Yes, need to replace charge port.

I set the charger to 32A and it works now every time but then noticed the high power draw.

Hoping Ford Service will fix all of the above at the appointment since multiple charging issues seem to be all muddled up here.

Ah yes, I see. I read the part about slow charging which hasn’t happened with mine, (it just says plugged in not charging) so I thought that was a separate issue.

You may have 2 different issues - charge rate derating due to charge port temp sensing In conjunction with a software change that limits charge port temps. And the battery heating system running on steroids due to bad software. The TSB linked above only addresses the second issue.

That sounds like it! I hope the TSB will fix both.

Not likely to fix both. This thread has 50 pages of posts about the derating with no solution.

Awesome…It’s been in the shop 3x now for the front sensor camera fault/no cruise control at all/PCM and Image Processor swaps…last time for 29 days and last time not fully covered under warranty due to mileage and not a “Powertrain” issue.

Luckily Castle Rock Ford is legit and comp’d a rental…but this is getting pretty frustrating. I LOVE the car, but the maintenance is getting so bad for a car with 40k miles on it.

I’ve wondered how these situations will play out for cars no longer under warranty. The car gets jacked up by an OTA update and requires a dealer visit to fix it. Who pays?
The charging system should fall under the 8 year EV component warranty, though.

Since it has been below 32 degrees I have left mine plugged in and when it gives the Preconditioning for Drive on Ford pass it is drawing about the same current it does when charging from my SplitVolt splitter. I doubt that mine comes on as often as it would if below 0 since we only got down into the teens overnight. When it is plugged in and idle it draws around .6 amps so there must be some things that are on if it is plugged in that might not be left on if it was not plugged in. So even at above freezing it will still draw some current when plugged in but that would be minor compared to when it is actually charging. I added a photo of the SplitVolt display when it was in preparing for drive mode.

Okay, I am 99% sure the car is not actually taking energy and it is FordPass assuming a constant 7.2 kw/hr draw because the Grizzl-E is steady green when plugged in during the time the app is saying it’s still taking energy. Maybe my previous high power bill was unrelated.
