For those new to BEVs, here's a useful resource from Ford.

Unfortunate they use 80% instead of 90%.

From the PDF:

Because a DC Fast-Charging Station can charge an all-electric vehicle so quickly, itā€™s a commonly used method for charging on long trips. What many owners donā€™t realize is that the vehicle automatically slows the rate of charging once the battery capacity is above 80% to minimize stress on battery components. Since the cost of DC Fast-Charging is often time-based, paying for that last 20% can get very expensive.

Yes, even with the charging curve update it's slower from 80 to 90% than it is before it hits 80%, but 42 kW charging at an EA charger is still better than having to make another stop. And going from 80 to 90% at each stop will eventually prevent another stop or two on a trip.

Wow, this is a big line here:
"On an all-electric vehicle, if the minimum charge level dips below 15%, the vehicle will discontinue charging the 12V battery in order to conserve energy for the thermal management system. "

Parking at under 15% with any drain on the 12v is not a good idea...

Iā€™ve only done one road trip so far but it would have been nice to get up to at least 85% without having to wait for an hour! This is from my personal experience at the EA station in Lake City, FL. At the time I did not trust the EA station in Gainesville which would have been my preferred charging stop!

So as a new MME Owner in a currently cold weather climate, looks like I'm better off leaving the charge limit at 90% if I don't need the extra 10% of range for daily driving even though temps are consistently <40 degrees. Seems like that's the way to go unless I'm going on a longer drive that will require the extra range.

Of course the only EA station thatā€™s at a Target and not a Walmart doesnā€™t work, still seeing 3 out of 4 down on Plugshare.

Cold or hot, you should charge at home to 90% unless you're leaving for a trip the next day.

In the summer months you can keep the charge at 90% but don't necessarily have to plug in daily as that 90% will take you a lot longer (for my CA Rt1 90% will last me all week: I usually plug in Sunday and Thursday nights--Thursday's so its ready to go for the weekend).
