I attached my charger today and it said 66% charged and 12.2- 12.3 volts. I then ran the charger and after about 2 hours or more it had raised it to 74% charged (15A charger). I then removed it because I had it connected to the positive post and remote negative body post which I believe is incorrect for charger since it bypasses the BMS. I am currently looking up the charging points, but suppose I could continue and leave it locked for 8 hours afterwards so the BMS resets itself, or do the BMS reset procedure.
Assuming I'm inferring your connection points properly, the remote negative post is correct. The only connection point which is incorrect is the negative post itself (or any directly connected metal to the post).
Thanks, I realize I was correct after all. Do I have to let it sit locked 8 hours or do the BMS reset after charging since the remote post will allow the BMS sensor to measure the charge voltage?
I charged mine and it reached 100% and after resting a couple hours the voltage was12.78V. It sat about 18 hours locked and I checked the voltage before my wife started it. It had dropped to 12.48V which is about 88% charged and I find that an excessive drop for that short a time. I then started the car and it runs at an elavated idle speed when it first starts cold, depending on the weather. The alternator (non hybrid) charge voltage at the battery was 13.43V which I find a bit low but might be within spec. Plan to measure after my wife returns running short errands (perhaps 30 miles total).
Just a comment. The voltage just after charging is never a 'real' voltage. It will never hold that value. It will settle to a lower voltage. In fact, manufacturers of batteries recommend a battery sit for 24 hours after charging before measuring their open-circuit voltage to accurately determine state of charge.
I discussed the values with the dealer and he said to bring it in for the newly released BMS update. He then told me that our vehicle was currently at 91%. Asked him how he new and he said he was looking at it as we spoke? I can find the tire pressure, fuel level and oil life on the lincoln app on my phone but not the % charge, is it also available on your phone or is this a dealer only item?
You are correct, I believe it was a battery drain update.
Good morning Naughty! You are correct and not missing any additionally reported "Vehicle Status" reporting data on the phone app. In order for whoever "the dealer" individual is, the only way to see that information would be to directly plug into the OBD-II port under the drivers side dash or have a battery monitor connected to that battery. Hope this helps.
Thanks for the response. Since the car was 80 miles from the dealer when he told me about the battery SOC, he must have been using old data, perhaps when the car was serviced before the sale?? I noticed when I looked at our phone the tire pressures were around 36 psi, at least 4 hours after it was driven and in our garage. So I assume the phone data was not live either, but the last reading taken when the car was parked hot in the garage. However, this morning the app shows 33 - 34 psi, so perhaps it is live??
The Lincoln way app display ( at top of VEHICLE page under banner ) indicates when it last updated - if it is not current you can swipe down to refresh.
Hi swindler. More than reasonable.
I just had to comment… The vehicle pretty much has just traveled between the back lot and the service bays. But the last record I have of any activity with the vehicle was 8/21, when they applied the ABS software update. That should be the last start/stop. And that was (lo and behold) 14 days ago.
Hi swindler. Thanks for the additional information. Then if that’s the case, let’s look on the bright side. The good news is … your battery is holding a sufficient charge for 14 days … and your BMS is working exactly as designed!
Well, more than 14 days I would think since the charge time for upgrading the ABS software would be negligible. And really negligible time doing any of the fixes thus far. But a minimum of 14 days, and on the outside, about a month. I can live with that. Thanks for your knowledge again, @bbf2530.Hi swindler. Thanks for the additional information. Then if that’s the case, let’s look on the bright side. The good news is … your battery is holding a sufficient charge for 14 days … and your BMS is working exactly as designed!
Keep us updated and good luck.
