  1. Onboard Charger Efficiency Measured

    This doesn’t make sense. You’re losing more energy at 40A than 20A (if this graph is accurate) no matter how short or long you charge.
  2. Turtle Mode With ~30% Left (Cold Weather Warning)

    Reduction was not gradual for me. It was less than 5 minutes from all good to red turtle mode and 63 MPH max speed.
  3. Turtle Mode With ~30% Left (Cold Weather Warning)

    Somewhere between -8F and 0F.
  4. Turtle Mode With ~30% Left (Cold Weather Warning)

    I had the orange turtle at 31%, red turtle at 30%. I would say don’t drive this car at all if you’re going to drop below 40% when temps are below 10*.
  5. PSA: Keep The Battery Warm So You Have Enough Cabin Heat

    I had basically the problem, Saturday but I got the orange turtle at 30% HVB while driving 70 mph heat set to 65F. I had to pull off the interstate and take backroads for the last 10miles of my trip. Its absolutely ridiculous how underpowered the heater is.
  6. How often do you charge your Mach E?

    Every night to 70%.
  7. Battery says 100% but range says 296 miles not 310 - closed no more input needed. thanks.

    If it’s actually really cold you’re more likely to see 200 miles. If many years old, more like 250. This is normal.
  8. Newbie here - 21 MME Premium AWD ER - charging help needed!

    How you have 3EVs but don’t know anything about charging is beyond me.
  9. Do you really use blue cruise that often?

    Way too many options on this survey.
  10. Preconditioning Improves Range up to 20% [Ford Brochure]

    Exactly. If I don’t precondition, the energy needed to heat the pack comes from the battery, killing my efficiency.
  11. If preconditioning is so good and important..... why no dedicated button?

    While I did not monitor it via OBD, I know what the charging curve is and I know I was well below it for the first 20 minutes. It takes a lot of time to warm up 1000lb of battery 60 degrees with a 4kW space heater. I understand why you’re skeptical, and I’d like to look at more qualified data...
  12. If preconditioning is so good and important..... why no dedicated button?

    Yes the faster charging speed more than makes up for the preconditioning energy loss, that’s the whole point. It makes a big difference. Last time I DCFC it was at least 15 minutes before my battery was up to temp and it wasn’t even that cold.
  13. Preconditioning Improves Range up to 20% [Ford Brochure]

    Mine would cost between $1.5-.25 a day.
  14. Preconditioning Improves Range up to 20% [Ford Brochure]

    I definitely get better efficiency after preconditioning because the car doesn’t have to waste battery energy to heat the battery to a decent range. Unfortunately preconditioning was pretty expensive, at least $20/month so I stopped doing it every day. It’s a trade off of battery cycles vs...
  15. Recommendations for L-2 EVSE

    Chargepoint homeflex hardwired. Has good form and function, never had an issue. App is good too.
  16. Smart EVSE vs FordPass - What Do You Use For Scheduled Charging?

    Why use FordPass at all? Set it in the car once and then forget about it.
  17. Best percentage charge at home for battery life

    There are literal scientific studies that show charge percent has a huge effect on battery degradation. Yes people will say 8% is better than 10%, not that it’s a lot. I want my battery to last as long as if can while being as usable as possible.
  18. Best percentage charge at home for battery life

    People will know because they will ask. It’s like knowing the mileage of a used car, hugely important. I wouldn’t buy a EV without knowing the State of Health. Battery degradation is a large factor in EV resale right now and will be super common for people to be thinking about in the future...
