New Lightning owner puzzled at the slow AC charge

[unicorn1]

I have a 25 Flash (a little bit smaller battery), but charges steadily at 10.4 kW all night on my Ford Charge Station Pro. I'm wondering if you have a loose connection or some overheating issue caused by some loose of defective part in the onboard AC charger. If you can find another level 2 charger to test on would rule out your Autel.

Yeah that’s what I’m guessing. The occasional spike looks suspicious and a just barely loose collection somewhere between Autel and Where ever in the line Ford actually has their inputs to the monitoring of the communication and or AC.
I saw a sharp vertical spike like that in my temp sensor on my Grizzle mini when it went south on me. I guess the onboard software could do it to if, as you say, the truck can now be manually derated.

Is the Canadian power grid 240 v single phase like US, or is something else 3 phase 220v 208v? Just wondering if any potential impact?

There is no appreciable difference between the US and Canadian grid. But I think you maybe confusing what most people think the grid is. By the time voltage gets stepped down below 400 (maybe 600 volts if your house has permanent staff… and you launch satellites for fun), it’s no longer grid. I guess technically your 120v receptacle in the bathroom is on the grid but once on the other side of the transformer it’s all the same. In North America you’re an odd duck if you’re running three phase in your house.

If is important to you and you can still return the truck, then do so. I am pretty sure that the dealer is not going to be of much use here. Unless you are lucky and there is some code being thrown that the dealer can read and then invoice Ford for a repair you are going to have a hard time. It is difficult to find a tech that could do a proper electrical diagnosis (why are they working at an auto dealer with those skills?) and if they had one, they don’t want to spend hours of tech time chasing down an issue with a non-Ford product. The guy with the bad battery is always going to take precedence.

To solve the problem you are going to need an OBDII scanner, which is not expensive. It plugs into the OBDII port on the left side of the steering wheel (under the plastic). You can read codes, look at the inlet port (and others) temperature, voltage, and current. I use a vLinker MC+ and car scanner pro which gets you all of the data but has an interface from the 1980s. If you find high temperatures being reported then you might get some action. If you find large voltage drops, then get an electrician to check your setup.

Good luck! I have been waiting 6 months for a minor recall that I have been to the dealer twice for (the second time they assured me that they had the part, only to give me the deer in the headlight stare when I got there after a 2 hour drive.)

i sincerely hope they can find the issue because i love the truck

Canadian 240 are two L1 and L2 out of phase from a 3 phased wire up there. So L1-Neutral is about 117 Volts and L2-Neutral is another 117 volt not on the same phase. L1-L2 is about 240 relative to each other.

An arcing loose connection would be pretty noticable at 50A. You would smell and hear it. Do any of the lights in your house flicker when the Ford is charging, but not when the BMW is charging (or any other odd electricial behavior).

An occasional spike could be that the truck is trying for 11kW and gets something that it or the EVSE doesn’t like (especially if the spikes are at a regular interval) so it drops back down to a lower rate. That would imply something like voltage vs. heat which would take longer. It is possible that the BMW is more tolerant of voltage drops.

After all this, it will probably come down to some setting that Ford added to SYNC. If they can remove my ability to turn off the alarm they can certainly mess up AC charging.

Does Ford do the free charger install in Canada? If you have them install the Ford charger and it doesn’t work, then you have a little bit more of a hook into them — and it might actually work better than the Autel due to some obscure reason that you don’t really care about.

No we don't have that

Well it seem the truck finaly abid to its specification. Knowing lithium chemistry it means the battery pack was in a "balancing mode" between the different cells which means maybe the vehicle needed to reequilibratre the voltage of some of its internal components. Now it charge regularly at 10.7. Nothing changed on the home charging station setup.

So the dealership did nothing and it just started charging like it was supposed to?

Do you charge to 100%?
