My 2015 has 62k miles and I am in AZ too and I have a 70 miles round trip commute to work and work in the middle of the desert with zero shade and I charge on 110 there during the day and when I get in my car at the end of the day it's 140-150 degrees in the car.

And at night it's about 105 in the garage and I charge on 220.

My car uses 4.5kw now until the battery is out. But when I get to work (about 1/3 city and the rest freeway and rural road) it usually says 20-24 miles EV. When I exit the freeway, I have about a 4 miles road until I get to work. I use the Empower screen and can usually stay in EV mode until just about up to the guard gate unless there's cars behind me and I have to speed up and use gas.

 Several months ago I think I was close to 5kw, so it's gone down almost .5kw in the last several months. For the first two years I was in California and now I'm in the miserable heat, so I think being in the heat has degraded the battery more than being in nice weather.

One thing we don't know is if the degradation is linear. In other words, just because you lost 20% in 17,000 miles doesn't mean you'll lose another 20% in the next 17,000 miles even if all other things are equal.

2014...74k miles...getting 4.5kwh from full charge/discharge now. About 18 solid miles depending on speed and a/c use

That is good for you.  My car has 57k less miles and 3 years newer and now I get about 4.4kwh.

When I checked last year at 50k miles I was at 5.4kWh, but I'm known to baby my battery.  Haven't checked lately.  I was going to check in a couple months at 60k miles to compare.

Who the hell buys a car, fairly expensive car, and then doesn't use the a/c? Dumbest thing i have heard. All this car is is an enhanced hybrid. Forgot all this charging and battery crap, whats your mpg? Thats all that matters.....mpg. My lifetime avg is 43.2 mpg right now. That's blasting a/c every single day, every second i am in the car....43.2. Thats the number thats important.

 

Hehe, amateur; my lifetime average was 96.5 MPGe... (and 219.8 watt/mile) before I sold with a range around 14. This was over 65,000 miles and 4.5 years. I'm sure there are hyper-milers who would laugh at my numbers too.

 

If you want to ruin your battery, absolutely ignore charging and battery crap; better for you to get the Hybrid. If you want the most out of the battery (a consumable), charge to 100% as close to departure as possible. Don't sweat it if you cannot. Things that degrade your battery are heat, high charge, and low charge states. Be realistic you cannot win only try to extend the life of your most expensive part if you can. Certainly use your AC, but also you can be smart. Run the AC while you are plugging in. Precondition the car as Ford allows. I had a sunroof that I only closed with the AC on...

I believe Teslas show your first year is the worst and then it levels off. I think Leafs could offer a similar usage, but I'm guessing it is people learning their cars. My Fusion was gradually getting worse and I never showed big drops, just slow decline.

I have 65k on my vehicle. I got 5.3 kwh on a full discharge today. The charge time was right at 2.0 hours. I have a little bit of degradation, but not bad at all. I don't charge during the summer. I will go months at a time without ever charging the vehicle during the warm season.

Trivial change in 70k miles. Just drive and enjoy your car folks. Put your pen and paper down and stop analyzing.

Oh, and by the way. My current mileage is with the swap of summer Z rated tires instead of the factory low resistance tires. So even less of a difference in reality.

For one, 22% degradation in 70k miles is not trivial.

 

But the reality is that those screen grabs do not tell how good your battery is.  Yes, you got 5.3kWh at 20k miles, but that included part of the hybrid portion of the battery.  The only way to compare apples to apples is to do the test where you drive from 100% charge to the point where it switches to hybrid mode and record the kWh used.  The kWh for that test compared to 5.6kWh for a new battery tells the degradation.

My daily drive costing me $.17 cents more now than it did two years ago is trivial. Sorry buddy.

Thinking of the summer, would it be advisable to have a fan running in the garage? Pointing to the underside of trunk? Perhaps with sunroof slotted open for ventilation? Obviously, I can also keep back door of garage cracked open a bit that would help to reduce the pent up heat rather than having the car soaking in it? Any other suggestions to keep the heat off the battery while recharging?
