I have been seeing numbers from the GoM and the M/kWh meter that were pointing toward a full charge range in excess of 300 miles for my FE4X, so I decided to go a couple days without charging to see what the range really looks like. I charged to 90% at work Wednesday, reset Trip 1, and drove home. my round trip to work and home is right around 70 miles, and seems like it takes 22-24% of my battery, so I figured Iād be charging back up today at around 20%. Weāll, I pulled in at work today and snapped a picture before plugging in, and it shows I drove 230.6 miles. Then I went to the FordPass hunk of shā¦ err app and saw that I had 15% charge and 52 miles estimated range left.
I started doing math, because thatās how I see the world, and hereās what I came up with:
90%-15%=75% battery charge, or 66 kWh, used. This is one place that I wish we had better, more detailed data because I seriously doubt I was dead on EXACTLY 15% (13.2 kWh) left, and those rounding errors affect the totals, but Iām gonna go with them because itās the best I have at this point and the car wonāt be back to 90% before I leave tonight to go home. [/rant]
Where was I? Oh yeah,
75% (66 kW) used to travel 230.6 milesā¦
That means 3.4939393939 M/kWh. Multiplying that M/kWh by the 13.2 kWh (15%) remaining gives us 46.12 miles remaining, which when added to the original 230 miles traveled gives us 276.72 miles on a 90% charge. That number is actually making me wonder if they didnāt rate the epa range based on 90% rather than 100%, but thatās speculation. Using math, that 3.49393939*88 leads me to believ that in conditions like Iāve driven in the past 3 days, I have a theoretical range of 307.466666 miles on a 100% charge.
All this math means that I am, at this moment, beating Fords stated range by 13.7%. So thatās cool. It also means my brain is tired now, so Iām done. ?
