CSP-23B57 for High Voltage Battery Notice

[Grease Lightning]

Dropped mine off today for the repair. Will let you all know the outcome, but I did not find encouragement when they kept referring to it as a recall….and even said goes other yeah Ford doesn’t know yet how they are going to deal with this recall….

Sadly something like this happened to me with my PHEV Escape. Ford did some minor tweaks to prevent a small chance of an engine fire, then came back a few months later and did a full recall because there was a “issue” with the main bearings that could cause “oil and or fuel” to Escape the motor if an internal part decided to be an external part. (pun intended)

I sure hope this software measure is not a precursor to a recall…

Just curious if any of you have received this. Today I logged into my Ford account and found two recalls. The first one I knew about, the rear light, but now I also had the below High voltage battery module or software recall.

Anybody else get this? My plan was to wait until the rear light parts are available and then make an appointment. Is this something serious or just a software update?

No warning in the truck or otherwise notifications.

I just received this in the mail today.

The notice came in while my April 2023 build was in having a tonneau put on it. They did the HVB check because the truck was there and they had the time.. On pick-up they said.. "we'll everything is good. The first two F-150's we had in needed a few cell replacements but yours passed with flying colors."

For those that did this update with FDRS...does the CSP notice then clear from your account/Fordpass automatically?

Only a software update but sadly the only software update….

They didn’t or could update the rest of the software. So still on an old version of sync and the old dash….so wish I could pull and install updates.

It might be worth giving your dealer a call, but given some of the experiences some on the forum have had with clueless dealer techs, maybe you outta wait for the OTA update.

But I wanna ask, how old is your truck, do you know the build date? How many months is it saying the battery age is? Do you charge to 100%? Do you often drain the battery below 40%? 20%?

I'm just curious to see what different owners battery health metrics look like in relation to how they use their trucks.

Build week 12/5, Delivered 1/5. Battery is 9.4 months. Battery SOC for most of it's life has been between 30% and 70%. On some weekends when I expect to go far, I may charge to 85% to 93% right before departure (It does not sit at high SOC). I may have charged to 100%, once. Truck has been in the shade for most of the summer. I have been babying the battery but there are other owners with the same battery age that are still at 100%.

I am very curious myself on how Ford measures battery health. If it is cell voltage variation from average, some of it may be a crap shoot of how many iffy cells you have in your pack and how hard you may have pushed them with hi temp operations. I am not sure about Lightning but Rivian has 7700 cells. If one bad cell can ruin your day, anyone still running is a lucky guy. I can't blame Toyota waiting for solid state battery.

Dropped mine off last Monday morning for the CSP and 10K mile service (Tire rotation). My dealer offered me a ride home. About 4 hours later they notified me that mine just needed the software update and that they would come pick me up in an hour. Overall it was a painless process.

Interesting. I believe you have around 30 more cycles on your battery pack than mine. If I had to guess how they're measuring health, it's probably based on capacity and maybe cycle count.

Cycle is total discharge with respect to battery capacity, right? In other words charging to 100% and discharging to zero on my standard pack has the same cycle count as charging and discharging from 30% to 80% twice. Both cases are counted as one cycle? Am I getting this right?

Yes. But cycling with deep discharges and full recharges will still induce significantly more wear on the battery.

Oh wow that's cool data to see, glad we can compare some of the more detailed metrics. Okay so I'm fairly certain after seeing your value that EvBatteryPackLifetime has to be cycle count. Although Ford doesn't let us see it in the UI, good to know there's at least a way to see it.

And I see, that's interesting. Yeah I'd almost say that 136 still seems too low for overhead. I vaguely remember some engineering data or something mentioning something like 141KWh or 145KWh. But yeah to me 158KWh seems like an exceptionally large buffer, but I guess it's possible?

I think we need to defer to @MickeyAO for an expert opinion on the matter and the numbers we're seeing!

If you are asking about the nominal capacity of an extended range battery, based on the stickers I've seen on the pack and adding up all the module stickers, it is 141 kWh

However, nominal can and will be different from actual capacity. In fact, I have seen the capacity of a cell increase with the first couple of cycles. I actually have to cycle cells until the capacity stops increasing for our very first test on a cell.

Once it levels out, it will start decreasing on any type of charge/discharge cycle. The only question will be how much degradation. We use a propriety L9 matrix to account for delta SOC, charge/discharge currents, and temperature. Once a week, we do a reference performance tests so I get to see the degradation in almost real time. See previous posts on what is good and bad for your battery.

So I have a Lightning to be delivered later this month whose VIN is affected by this CSP. I am concerned that Ford did not fix/update my truck prior to sending it off to the dealership. I plan to confirm whether or not my truck has had this CSP done before delivery. If it hasn't, should I make it a condition of the sale, refuse or accept delivery anyway?

I'll let the FDRS guys chime in, but IIRC it might take a couple of days for the truck health records to clear of resolved recall items and CSP's, are you willing to delay the purchase to see the flags cleared, even if the tech' & SM said it's "FIXED"?

 

[Maxx]

Well all this talk of battery module issues and failures had me concerned so I rechecked my battery stats live data from the BECM via my OBDII dongle and it would appear that my battery is still healthy as a horse.

Any of you guys have an OBDII dongle and wanna compare data?

My SOH 98.5% but battery age is 4 months younger. My battery Voltage shows 328.25 V (at SOC of 42%), HVB SOC MV 0.36 HVB MV 0VM.V

Am I misunderstanding everything, or is this not that big of a deal? My understanding on this is that it is a software update so that the battery will be watched better and will shift it into a reduced power state before the battery gets too unstable, right? Like I'm not concerned that there is something wrong with my truck, it's just more a software update that they want to push out.

Ford did have a few Lightning fires at the factory a while back. The way I read it, for most, it should not be a big deal. For a few it may be. I didn't get a letter for any of the other updates.

I'm just not understanding how Ford couldn't turn this into an OTA within days and get it out to the vast majority.

Do you really want to rush Ford's software development team?

 

[mattskr]

Went ahead and did the updates with FDRS then ran the battery health check. Deviation looks good as all are within .004 of each other. But what do the cell capacities tell me? Is this the capacity of each cell at 100% or does it reflect their current SoC (I was at 71%)
