Mobile Charge Distance at 90% only gives me 375 kms which is way less than advertised.

[Gerryjoe69]

I charge my Lightning Extended Battery at home using the mobile charger to 90 % and I consistently only get 375 kms distance at 90%. Is this normal for 90%. All I have read said full charge is 515 km. So 90% should be at least 463 km at 90 %

Many threads on this. It's called a "Guessometer" for a reason. It takes into account recent trips. So in winter months it will be lower due to the battery not being as efficient as in warm weather. Ditto for driving uphill, into the wind, towing, etc.

You forgot phase of the moon, astrological sign, and the price of Bitcoin.

To add to that, the battery will try to heat itself at times in colder weather so you can have hvac losses regardless of if you wanted heat in the cab.


Then if you are “preconditioning” to the next charger that will have some losses.

But the biggest is speed. If you are driving faster the 65 mph the distance in the “tank” will take a large hit on the guess-o-meter

That makes sense thanks....when I first purchased it was in the 400km range and as I have driven it to work it started changing and I assume based on my trips.

You can go in and reset EV Driving History also. That will give you the default mileage (535km/ 320 miles) on the screen, but it doesn't actually give you any more miles, just might make you feel better! Until it starts dropping quickly and then you panic!

Moved this thread to the Charging node, where we have multiple current & ancient discussions on the topic.

Go to the dealer ASAP they put the wrong battery. You have a standard range vice extended range battery. I’d reach out to Ford’s BEV team and @Ford Motor Company on this forum. This issue has got to stop with the wrong batteries on extended range
