oh man, if I had seen this spreadsheet before buying I would of ran for the hills. Purchased a 24 Flash 2 days ago and "Powertrain malfunction" has appeared on my dash. It doesn't appear that I have reduced power but I'm also still learning all the displays. My gear shift also does not fold down so I'm hoping it's just that?
Chances are good it’s not a battery module. Nearly if not all that have had that failure have seen power reductions down in the 60-50% range.
A few folks have had subsequent failures, hopefully they are a minority, until it happens again enjoy your Lightning.
See my signature for the link to the spreadsheet. Yes, several folks (see the Red highlighted lines) have had multiple battery module failures. What is the build date on yours? (driver's door, top of info sticker)
Please read through the comments... and/or see my spreadsheet in my signature for a condensation.
If what you said is true, I am guessing since modules are connected in series BMS is bypassing all modules after the bad one. So on my Pro if 4th module goes bad, I will be around 50% power and 50% voltage. Which means remaining packs probably will stay at their last charge level. So if they were at 100% it is not good for them, if they were at 50% they are OK with a long wait. However the first 3 packs will have to pull double duty until the rest come online. In your case since you have 9 modules, It looks like 3 of them may be out. If they were all the same size you would be restricted to 67% but one of the modules is smaller so 62% sounds right.
As to your image, I think only the dealer or someone with Ford software can see the 96 individual cell Voltages and Capacities? In the case you are showing, Cell #18 is the lower Voltage than normal bad one. The Car Scanner App via the OBD2 port can show a "HvbMinModV" (High Voltage Battery Minimum Module Voltage) but not individual V+Ah of each of the 96 cells.If they were all the same size you would be restricted to 67% but one of the modules is smaller so 62% sounds right.
This is all a gut feeling and I have no idea how it really works. If anyone does please do share.
Everything you said is correct and not in conflict with anything I said. I did not mean to imply you can get that info from Car Scanner. It was just visual aid. What I am asking is if people who have had power reduction, using car scanner still see their Battery Voltage in mid 300 V range or in case of 50% reduction guys it is bellow 200V. That is something you can see in Car Scanner. You can also see HVB Module Voltage variations in Volts and in %. Mine is always either at zero or close to it. In case of the failed module 2 I posted above, the ODBII should show around 0.16V or 4%.
That's about as good as you're going to get for a module repair. Sounds like your dealer knows what it is doing, which is encouraging for you. Multiple failures do happen, but are rare. I think someone shared the retail price for a module was around $5k? I'd have to dig around to find it.
