Long time owners with OBDs ...whats yer HVB SOH ?

[CMRD]

2022 RWD. Ext. battery mostly home charge between 40 and 80 %. DCFC 4 times. SOH 94.5

Oops. 32000 km; 20000mi

Also worth noting that you should read the OBD several times and take the average of it as well to check outside temperature. My first reading was 89%, then a month later 91.5, and yesterday it was 90%. Temperature range on the tests was 17-25 degrees Celsius, so will have to wait until it’s 25 again to get a new reading.

Btw: great topic, hope it keeps traction over time. Nothing like having actual datapoints to inform users / buyers

That’s interesting, thnx.

May explain why mine read 89% at around 85,000 miles and 91% at 91,000.

I put it down to SoC, 80% first time, 100% second time.

Would’ve thought temperatures would be fairly similar as car ALWAYS garaged and temperatures shouldn’t vary too much though you very may well be correct and I don’t know for sure about temperature as I didn’t measure it.

In light of your thoughts I will check temp at SoH test in future.

Again, thnx.

Edit: one other thing is the SoH test at 89% SoH was without a charge, the 91% SoH followed a full charge.

Edit: just did a SoH check at 27% HV SoC and 18degC ambient showing 91% SoH @ 92,560 miles just after HVBJB replacement.

My 2022.5 Ex AWD at 35000 is 93-93.5

I'll try to pull the information into an easy to read spreadsheet so you don't have to read every single comment/reply . ?

did you already start pulling responses into a spreadsheet / any interest in letting me hijack this thread via a google sheets survey that people can submit and review analytics on their own rather than you manually transposing? i'll DM you

Yeah I pulled the latest results ( #68) and did a little deep dive in posts 69.
PS If you guys got a thumbs up from me I have your readings but haven't added them yet to the spreadsheet . Every time I do it daily someone comes in just minutes later with a new reading .
Doh .
Don't wanna blow up this thread needlessly so I'll post new results maybe every other day as long as new reports come in .
Thanks to all who've replied so far .

 

[AngryMan]

The interesting part will be when the LFP batteries start reporting . IF you have one and are reporting please bring it to our attention .

 

[AngryMan]

ok the latest and greatest up to date

 

[flapjake314]

i ended up creating a google forms and self-updating analytics so angryman doesn't need to manually type everyone's inputs over and over again

i made a new thread here but also fine to merge the two threads, goal is just to have a long term tracking of this topic for all our users

i already uploaded all of angryman's work so far so no one here needs to redo

So i finally figured out Car Scanner.
37,914 miles
GT with 29.14 months of service on it (march 2022 build)
SOH = 96%
very seldom DFHC - still have not used Ford's free high speed charging
I charge for free at work on L2 charger, so I usually charge to 100% most of the time, I seldom let it go below 30%
Normal driving, still have stock tires.

'22 GT, 41,358 miles, hardly ever DCFC, SOH 95.5%. I generally charge at home to 90% over night

 

[Mach-Lee]

FYI after taking a road trip with multiple 10% to 100% charges, my SoH increased 1.0% to 94.5%.

If you only charge to 70-80% daily with shallow charge cycles (best for battery health), you may see a drop in the SoH due to insufficient BMS calibration data. If you do not charge to 100% often, performing a BMS calibration with deep charge cycles will likely increase the SoH estimate by 0.5%-3%. The actual battery condition will remain unchanged, you are just updating the software estimate of your battery's capacity. My recommendation is to perform a deep charge cycle every 6 months or so (every month with LFP) to keep the BMS updated.

DId you have the HVBJB recall work done yet? I have the same car and had the same SOH (96.5) at 40k miles right before the HVBJB recall work. Right after the recall was done, the SOH dropped to 92%. Some how the recall ( with its various module software updates) caused the HV SOH to drop by 4.5%

I don't know if it would "correct" your readings but maybe try what Lee described in comment #87.
He's our resident guru
