Am I charging to the maximum capacity of the battery and using the buffer?

There seems to be a select few of us that are having a software bug where the bms is not able to properly detect or display the true SOC. Mine is currently showing around 5-8 kWh off of true dSOC. This weekend I am doing the deep cycle bms calibration to see if that helps since I normally don’t go low in the pack thanks to @MickeyAO hard work.

As more and more people are posting about this happening, I suspect we will be hearing more from @Ford Motor Company about another csp….

Yes this could be a real problem.. my reported SOC is about 5% MORE than what Car Scanner is reporting.. So i tried to recalibrate charging to 100%, charging completed but car scanner only reported 96% SOC... so then real problem is when I drive it down to 10% coming back from a long trip typically for the last leg where I'll charge at home... I'm actually rolling in at 5% though the truck thinks it's at 10%... I could easily end up stranded on the road...

Exactly that is my concern too. We have already seen that situation play out as part of Out of Spec’s issues with the press fleet lighting that’s BMS got off and caused them to get a tow when they we around d 5% dSOC.

As it just started I am sure it is a bug or us needing to calibrate like Teslas have to keep the BMS balanced. I have faith @Ford Motor Company is aware or will be aware and have a solution

I’ll hopefully report back in 9 days how the re-calibration goes. I only consume about 10% per day.
