timmiles Posted July 9, 2016 at 06:36 AM Report Share Posted July 9, 2016 at 06:36 AM Hey everyone! I have a question for you. This evening I charged my car from 0-48% while shopping, this gave me a total of 8 miles. My commute home was 12 miles and half was uphill, half downhill. The uphill portion I used EV later but the second half of the journey was all EV. My commute summary said something like "total miles 12.3, EV miles 7.2 and regen 1.5". I am getting confused because when I arrived home, my battery was still around 40% with 7 EV miles remaining. How did I manage to make this trip, keep my EV miles and still travel 7.2 EV. Is this because of the hybrid mode and simply my downhill driving for a few miles? I am confused how it all works! Thank you. Quote Link to comment Share on other sites More sharing options...
murphy Posted July 9, 2016 at 09:42 AM Report Share Posted July 9, 2016 at 09:42 AM When you are going down hill regeneration charges the battery. Watch for the up arrow at the top of the battery icon. If you were at the top of Pikes Peak, with an empty battery, it would be fully charged during the drive to the bottom. Also when in EV later the battery is not used to move the car. soon2ford 1 Quote Link to comment Share on other sites More sharing options...
rbort Posted July 10, 2016 at 04:11 AM Report Share Posted July 10, 2016 at 04:11 AM Ideally you want to get home with an empty or close to it HVB. If you only had 12 miles to get home, 6 of which are uphill and the rest downhill, I would have tried to make the 6 miles uphill in auto mode. If you got to the "summit" the rest of the trip even if the battery was at 0% is "free miles" and you will get to your house with more than 0% if indeed the average is downhill of the last 6 miles. Next time try it and you might make the trip without disturbing the engine and/or using any gas. If you find that you don't make it, and say you are short 5% battery to have made it, the time after that, wait 6 minutes in the parking lot while charging to gain that 5% (you get 5% every 6 minutes on 240v on average) and leave 6 minutes later and you'll make it all on battery. Also going slower and letting the car lose some speed up the hills helps to increase the range, after you've lost that speed you can gain it back on the downhill side, slowly, letting gravity help you. -=>Raja.

When the car is in EV Later you are still counting EV miles because the ICE doesn't run 100% of the time. That is where the EV miles come from. It's just a count of how many miles were traveled with the ICE off. The regen miles are an estimate of how much energy was recovered through regen braking. Instead of displaying that in a unit of stored energy (kWh for example), Ford chose to convert that number to miles. If you did not have regen braking you would have wasted energy equivalent to about 1.5 miles of driving in this scenario (likely about 0.3 kWh).

Also when in EV later the battery is not used to move the car.You can also get a full charge coming down Mount Washington in NH. Did it last week, well, mostly. I had the A/C on full blast, lights on, everything else that could be on, on, and was intermittently putting the car in neutral to make sure I didn't overcharge the thing. So I'd use the normal brakes only for a short distance, then drop it into L and let let it put in charge. Last year when I fully charged the battery going downhill (Blue Ridge Parkway that time) the car shut down, threw nasty warning signs at me, stopping the accelerator from working, etc etc. So while I COULD have put in a full charge, I chose not to, hitting perhaps 80% full by the time I got to bottom. But if I had been willing to risk the overcharge, Mount Washington would have worked fine! Quote Link to comment Share on other sites More sharing options...
rbort Posted July 21, 2016 at 07:18 PM Report Share Posted July 21, 2016 at 07:18 PM (edited) I though about going up and down mount washington EV style, they even provide a charger at the base so you can charge up before you go up. However, my intuition tells me that its a very bad exercise for the car's battery and a good way to put some damage on it. First you have to draw it hard to climb up and mountain and heat it up, then you end up recharging it at a high rate of charge, much higher than L2 and heating it up even more. Your car throwing all kinds of warning signs and complaints makes sense. Not the best idea unless the car is a rental, so there! -=>Raja.
