HV Battery Calibration Procedure

Depending what DCFC are around you, you could also charge to 100% at one of the slow 50-62 kW chargers that tend to be in much lower demand.

You are correct that you will not be able to do the full calibration procedure. Based on your situation, I would recommend you try to find a public Level 2 charging station in your town and do a monthly charge to 100% on it (perhaps after you hit 80-90% on the DC charger).

The periodic charge to 100% is important for LFP batteries to reset the coulomb counter of the battery's capacity to full. The periodic charge to 100% will prevent the sudden early drop to 1%.

If you cannot do regular charges to 100%, then I would avoid going below about 40% due to fear of running out of charge unexpectedly due to an uncalibrated BMS.

This is one of the pitfalls of owning an EV with no at-home charging. Given that situation, I would recommend getting the extended range NCM pack instead of LFP.

Thanks for the advice, Lee. Your knowledge and expertise is greatly appreciated. There is one public L2 in our town, which I will monitor to determine off-peak times. I should be able to make the combo of DC 80-90% followed by an L2 top-off work.
