Plus Ford's asinine 12V charging logic for the Mach-E. Which they could fix in an OTA software update.
The headlights generally work as they are supposed to. I have had it switch from AUTO to ON sometimes. I'll talk to my dealer.
I still can't believe how bad Ford engineers are. I've said it before, and I'll say it again:
I don't save power when gaming and do not care if my car is sucking power when on L2. Problem solved. Fire up the whole car as it sits there in silence sucking minimum power and updates itself. I am sure that would not bring down the grid and is pretty inconsequential also. Question is why would they be scared of firing it up once in a while to maintain itself? It does when really cold "now" (auto preparing to drive). It does not need to be only when driving or charging that is just strange logic?
Close those contacts and run off the power supply (big battery) to install
The fact that they designed around this legacy problem just reinforces my belief that they suck at their job. "Hey, Bob, this legacy design is going to make OTA a real problem that will be impossible to fix later. Should we fix it now, or wait several years down the road and make customers with the current cars stuck with this un-fixable flaw?"
You could EASILY put a message in the update process that x% of the HVB may be drained during an update if that is an issue. But Ford has an aversion to giving us any info about what our car is doing. My last few updates have taken weeks to 'complete', but I have no idea why. All my screen says is 'update not complete'. It won't even tell me if this is an issue or not. And don't get me started on the fact that it's 2023 and my EV won't tell me what speed it is charging at...
But then why isn't it charging enough to get the update done? If an update is pending, then make sure the 12v is at or near topped off, so that when you DO start the update at night, you won't need to charge for very long (if at all) to get the 12v to the minimum needed. And you can even set some minimum 12v level and HVB level before such a charging/update process starts if they are worried about a drain on the HVB.
It really has no possible excuse, I’ve discussed it here before as well with @Mach-Lee and others and no one has provided a real reason. The battery is very tiny, it truly boggles the mind that they choose to not keep it topped off while *plugged in*, which currently leaves owners unable to get into their car when it gets too low.
This is so ridiculous, we’re just saying to charge the 12V battery while the car is plugged in to be *CHARGING*. How would the HVB lose any charge while plugged in?
Yes, it could be topped up more often with minimal drain from the high voltage battery. The idle draw of the Mach-E to keep the modules awake is only 300W, if the car woke up for an hour a day to charge the 12V battery from 50% to 90%, it would only take 300+180 = 480 Wh or about 0.5% of the HVB. Ron's figure of 5% is 10x overstated.
Which Ford may have just addressed with
Thanks for the link. Looks like informed speculation so far; looking forward to future confirmation. Fingers crossed.
