Charging oddities

[Erick Recors]

Hello,

New energi owner (and I love it). I dont' get the charging though, some days I wake up and I have 28 miles other days I have 17, most of the time the regular 21. Is there something that influences this?

 

Also, has anyone got the 240v charger? I'm contemplating getting one as I already have the hook ups for it and I find myself plugging in often only to need to leave again an hour later (which gives me next to no charge with the standard charger).

 

Thanks!

My estimated range varies as well.

 

The software estimates your range on the EV battery based on your driving history.

 

So your estimated range will vary with your driving history.

A L2 (250V) will more than double the rate of charge (4m/h v. 10m/h).  By the way, it's a EVSE not  a charger.  The actual charger is built into the car, this is just a power supply.

Yep -- in the winter mine might be as low as 18 or 19, but this past weekend I got mine up to 40.  So it varies quite a bit and is based on the most recent history.

Yep, get the 240. Sounds like you are in and out as we are also. Believe me without the quicker charge there is no way we would still be on the original tank of fuel after 16 months. Sometimes we have only just enough time to recharge partially back up which is just enough to remain in EV.

say what, it will give me 40 miles to a charge instead of 21??!  How is that possible? Do you have to replace something in the car too? I would be surprised Ford wouldnt sell it standard so they could say 40 mile charge.

no, I said 4m/h, which would be a charge rate of 4 miles per hour at 125V (the EVSE that came with the car).  If you buy a 250V (L2) EVSE you can charge your car twice as fast ~10m/h.  It's a faster charge.  It's not increasing your battery capacity.

Long trips with lots of regen along the way - I was out of town over the weekend with lots of big hills in PA... I don't let the HVB run all the way out (switch to EV-Later when it gets down to about 2) and then go back to 'Auto' when going down those big hills and then switch back to EV-Later when going back up the hills, thus banking the HVB (on a good long hill you can bank 1-3 miles or far more out in the Rockies) for later on slower/level roads where the HVB will do more good with more EV miles than on the interstate.  So with a long trip doing that many times, that means the regen and building of the HVB is much more than the everyday behavior, and thus the system predicts the higher EV range on a full HVB given that the same behavior will apply on the future trip.  However on successive trips where you don't do that, it will make its way down to normal, as my charge after the AM commute was down to 36 and after the charge following today's PM commute it will probably be closer to the normal 30-33 that it shows on most days when the expected commute is involved (during favorable weather conditions, that is).
