I am not getting rid of it for financial reasons. More for the uncertainty. I would hate to have a module replaced, and then a week or 2 later it happens to one of the other modules that is over 100k. I understand that it can happen to any vehicle, however with the SSM out and it seemingly happening more and more recently, it is just difficult to trust this vehicle going forward at high mileage.
@Ford Motor Company being completely silent on this topic really isn’t helping anyone…
Seems needlessly wasteful if true. Also, if that is the case, where do they get the refurbished or re-manufactured arrays the warranty allows them to use?
This is a great point. If I'm paying for a full swap, I'm keeping the old module.
To replace cells on a module, you have to match voltage/age to achieve a balanced system.
But doesn't Ford do exactly this when they replace one module (40-55 pouch cells) and bench balance them to the other aged 8 modules (hundreds of other pouch cells) in the overall pack. I am not claiming to be an expert, but new cells are balanced to old cells either way?
When you replace a module with a new one you need to pre-match voltage, capacity, and internal resistance within tight tolerance (often ±10% or tighter).
MODULES are balanced to each other ..... the cells within the NEW module are already balanced as a group out of manufacturing, but the 'group' aka module needs to be in sync with the other eight modules.
Right the dealership is not going to do a cell level repair, but that's absolutely happening in the real world at specialized facilities. Whether or not Ford ships modules back to a remanufacturer I have no clue, but the principle I'm describing exists and it seems like a valid approach to cost control as well designed for repair as the Ford pack appears to be.
I'm under the impression the physical limitations of disassembly of the cells from the current collectors is a concern, the way they're welded cell by cell makes for a challenge re-welding all the cells with the new / reclaimed cell from other packs to reconstitute a good module.
If all your original modules are fairly degraded and one goes out and needs to be replaced, does that mean it can't be replaced with a new one since it would outside the tolerance?
He doesn't need the diagnostic fee to know what the remedy is. Needs a new array.
If 50,000 miles were guaranteed, say by Ford in the form of an extended coverage agreement, then sure that's a sound point.
I wanted a price for them to replace the module. I know what the issue is (or will be since it’s still not an actual problem). Truck still drives fine, however it’s the uncertainty. Especially driving with kids and for work daily not being able to be out of a vehicle.
