I have had my Mach E for about a month now. I have been using it for commuting to work, and have been charging mostly at home. I did a fast charge at the EA facility in Clarksville, IN just to make sure it worked, and my Ford 250 kWh worked as well. The rate was lower than I thought.
I live in Lousivlle, KY and I have a trip to St Louis I would like to take in the MME, and I was curious how much time to budget for charging stops. I plan on charging to 100% at home for this trip. The first stop from my house to the EA in Clarksville is about 20 miles. It took me about 8% to get there. I wanted to see how long it would take to get from about 92% to 95-97%. The next stop is the EA facility in Mt Vernon, IL. It is about 186 miles from Clarksville, IN on I-64, and no other L3 chargers are on I-64 along the way. I could detour if needed, but that is not optimum. The L3 in Jasper, IN is a 34 mile round trip detour and only 50kW, the one in Evansville is a 60 mi round trip detour.
So, I drove to car to get the car down as low a charge as I was comfortable with, and got it to 3% SOC on the display. I then settled in for a long charge all the way to 100%, and got my pencil ready to chart this. I know the Ford updated the charging rate last fall, but couldn't find any data, so I plotted my own. Conditions at th time was 48 deg F outside temperature, battery temperature started at 51.8 deg.
This first chart shows the new rate compared to the old rate that Inside EVs has posted. I overlayed the 2 to see how closely it matched up. It matches well until 80%, then is a big improvement to about 95%. The battery temperature at the end (100%) was 87.8 deg Fand outside temp was 46 deg.
Overall, it took me 1 hour and 41 minutes to charge from 3% to 100%. Of course, the last 5% was the slowest. Here is a plot of the time it took from 3% to 100%. I've extrapulated charging from different points, say 20-80% and how much time it will take. Here is what I came up with. Maybe others who have done this can see if matches what they've seen. Of course, temperature can change these estimates.
The last chart is interesting. I had my VLink OBD2 plugged in monitoring the charge, and observed when I first started, the display SOC was 3%, but the OBD said the car reported 7.48%. It reads higher than the displayed SOC below 35%. It matches from about 35% to 60%, but then it goes the other way. The displayed SOC is lower than what the OBD2 says it is from 60%-100%. So as others have said here, a displayed SOC of 100% is about 95-97% if you read it from the OBD.

- 20%-80% - 38 minutes
- 20%-85% - 46 minutes
- 92%-95% - 7 minutes
- 92% - 97% - 14 minutes (for that top off before my long leg to Mt Vernon)
