Charging

[steveb]

Hello, I bought my lighting at the end of December and have only been able to get it charged up to 240 miles of range at 90%, most often it tells me that it's at 90% and my range is only 123 or so. I only use around 40-50 miles of range a day so it's not a big deal but I'm curious why? I thought that it might be the cold nights but it's not very cold now in Portland, evenings are getting down into the low 40s. I did install a canopy and lumber rack in February but that didn't change my charging range. I charge at night during the off-peak hours.

what trim level did you buy? SR or ER battery?

Charge amount is measured in kWh, not miles. Ignore the GOM.

Hey Steve,

For us to really help we need to know which pack size, you average mpkW average, speed, and climate.

all or those variables impact your range.

I understand that it is measured in KWH but where to I see that while driving and why wouldn't that be a direct relation to available range?

This is a flash, and the battery is an ER version.

Charge to 100% and pre-condition/set a departure time, see what it gives you. Under 100% especially in that 32-40 degree range I find it does a decent job of reducing the GOM by predicting the kw drain to heat the pack and interior to operating levels.

Being it's not "cold" are you using the departure time? If not suggest doing it and see the range difference still set at 90%.

 

[steveb]

My average mpkW is about 2.0, 10% climate and speed varies but mostly I'm around town so it's between 25-45 miles an hour.

You get % SoC and MPK. As long as you understand those numbers, you’ll be fine. Ford’s range calculation can be way off at times, unfortunately.
About 2.4 MPK gets you rated range. Your climate use is making it lower.

The fundamental problem is that range isn't a quantity that can be measured. To accurately measure it you would have to predict the future driving conditions. Obviously that's impossible.

The truck doesn't know if you're going to be driving 90 MPH into a head wind up a mountain, or putt-putting around town at 20 MPH. It makes its best guess based on some combination of recent driving results, maybe your route planning if using built in nav, and who knows what else. But the point is it's an estimate, and is rarely accurate. If you yourself know that the conditions will be the "same" for the next bit of driving then it might be close, but it can never be truly accurate. (I put "same" in quotes because, at highway speeds, even a light breeze can dramatically affect your efficiency either way, and that's really hard to detect even if you try.)

Even the remaining battery capacity/percentage is an estimate. It's not a physical quantity that can be measured, like the level of liquid in a tank. It's inferred from the cell voltage, but if the battery gets hot or cold you might not get the amount of energy out of it that you expect.

Bottom line, don't worry about the range number. You'll get used to doing your own estimates in your head which will probably be more accurate.

Potatoe is correct.

Ford could make it a bit better by including a more short term efficiency and range estimate, but they don't.
Heck, the 09 Prius we had included a rolling average display, why Ford can't include one is a mystery.

Multiply % of Soc x MPK and you get your current range, I think that's what you're saying. But shouldn't my baseline when fully charged to 90% of 230 miles as advertised range be 207 when I get into the vehicle in the morning? I feel cheated out of 67 miles of range every morning, does yours do this?

 

[TaxmanHog]

capacity x SOC x MPK (real or Ideal) = range

131 x 0.9 x 2.44 = 283 miles perfect conditions at 90% SOC

131 x 0.9 x 2.00 = 236 miles real world conditions at 90% SOC

131 x 1.0 x 2.44 = 320 miles perfect conditions 100% SOC

Got it, thanks!
