Truck died 5 miles from home

[Grease Lightning]

Charging for 5 hours so far and still 0%. I recalled that I have an OBDII scanner. Anyone want to tell me what this means? The voltage should be close to 400, correct?

Looks like it is charging. You said it was lvl 1 so you will be around 1kw per hour. From the app it looks like the SOC is still under the bottom buffer. That is why it is showing still 0% SOC on the dash.

The voltage will increase as it charges, but is low right now. That said I have never checked my voltage at flat zero so At 82% DSOC mine is at 379v

HVB taking in .32 kW. In 5 hours thats only 1.5 kWh. Which is about 1%. It shows 3% SOC but 0% displayed.

Voltage won't be close to 400 at low charge. As charge increases voltage increases. Think of testing a AA battery. Charge is proportional to voltage.

.32 kW is quite low for level 1 charging, I have been getting 1.01 for reference. Something isn't right. You are actually at 3% state of charge.

Wait a minute, "HV EV Battery power" should be negative if you are charging. Something is wrong.

By the way, did you happen to have car scanner on when it died? I would love to see a graph of the data when this happens. I think the BMS drifts and preventsng charging to the appropriate level.

Here is a graph from another thread. While doesn’t go down to zero it gives a nice representation of the voltage based on SOC.

Well she is back from the dead. It took 6 hours of level 1 in the driveway, but I finally got HVBSOCdisplay to 1%. I was able to drive into the garage and hook up to level 2. Could not drive until the truck showed 1% even though the battery had some power. Looks like I won’t need a ride to work in the morning after all. Screenshot right after hooking to level 2

How hot is it where you are at? Your batteries have not cooled at all. Don't charge to 100% in this sort of heat.

Looks like the forecast was for mid 90’s which maybe added to the drop if the truck was trying to cool the batteries.

You should be able to take it to 0 percent. If it doesn’t make it there, that’s not your fault.

I mean technically we take it to 0%…

We just seem to have different definitions as to the order of numbers. I was under the impression it goes sequentially in increments of 1.

I just saw this, what you went to rough is “normal” as in same as my experience in terms of a slow recovery and charge rate after it dies. It took me several hours to recover using a L2

Take it to the dealer but be prepared for a non answer, I was told my first time it was the BMS. Second time it was a bad module. 3rd time, I didn’t even take it. I’ve come to terms Ford doesn’t actually have a fix or know what the problem is.

For me, the commonality was DCFC. Multiple DCFCs caused the BMS to get out of sync and be inaccurate. But you didn’t DCFc on this right? It was a straight shot?

I think the high was 92. I did order it with Max Tow.

 

[TaxmanHog]

It was at 100% when I set out this morning. Then I charged 60% to 90% for the second leg home. I charged to 100% about 2 months ago as well.

I must have missed that, thank you for pointing it out.

So that’s still the most probably working theory is that multiple DCFCs cause it to go out of whack.

I picked it up at Houston Intercontinental Friday with 33% charge; charged twice DCFC on the way to my to my daughter's (arrived with 73%). Level 1 there until Sunday morning to 100%; Charged DCFC in Columbus from 60% to 90%. .9 x 131 is 118 kWh. I averaged 1.7 mi/kWh which should have used 105 kWh leaving me 13 kWh or 10% in reserve.

What I'm hearing in the past 12 hours:

Don't charge to 100% in heat.
DCFC will cause the BMS to go out of whack, so don't trust how much charge you have(?).
Don't be surprised if it dies when you get to 10%.

It all boils down to "sell the truck" if you want to drive it over 170 miles in South Texas. An electric truck is not for the open roads in Texas.

I think it goes out of whack on that DCFC

From your daughters to Columbus, what was your efficiency and how much did you take in at the charger?

Since you used 40% (52.4kWh) if you got 1.7mi/kWh then Columbus should be 89 miles from your daughter. Does that seem right?

Then charging 60->90% You should have been charged for 39kWh of energy - assuming zero losses. So realistically even more than that.

Are your actuals vastly different than that?
