Today when I got in my car it read 38.4 EV miles. My car is a 2017 Prius Prime and I guess charging it every night hasn't hurt the battery at all. Wondering has anybody in the warmer climates are you constantly getting high EV mileage? Posted via the PriusChat mobile app.
Yep, with the warmer temps, high 30's and even 40's are common. Personally, I'm in the 38.5-39.5 area recently in NJ. I have a 2017 Prime also. I've not seen any degradation of the battery in the 2 1/2 years I've had the Prime.
We pretty much all see the same. Lower range in winter (in the low 20's perhaps), really nice range in the spring and fall with warmer weather and no HVAC (mid to high 30's), then a bit less in the dead of summer with more HVAC use. The specific differences depend on where you live, of course, but here in Nebraska that's what I see. I would ignore the estimated range. That's only an estimate, and frequently is not what you will actually achieve. I only pay attention to the actual range. Today, for example, round trip to downtown. 22.3 miles total, inbound in the morning when it was 82F, then back home when it was 95F and the car had sat in the sun. HVAC quite a bit, battery on the round trip went from 100% to 30%. About a third of the roundtrip is expressway at 67 mph (a battery killer). As they say, your mileage may vary.
From what I read, those who live in warmer climates get lower EV range in summer due to heavy AC use. I, on the other hand, living in a colder climate am enjoying longer ranges in summer. Currently up to 39.2 miles, hoping to see 40 miles before winter sets in.
A Prime in the sun (with the rear hatch window almost horizontal) becomes an easy bake oven. If I park mine in the sun (particularly on a hot day), it's quite toasty in there when I return. No, I don't want the windows tinted. i look for shade for parking, but can't always find it.
Cool! Congrats! Nowhere nearly that high on our 2017 here in Austin, TX. I think the highest I’ve seen is 35, and that was only a few times ever. To keep up the high “range” (better term than “mileage”), keep charging right before driving. Remember that! I went through a period of charging up the night before (quasi-free) at the local mall, leaving it mostly charged overnight. After a couple months of that, the range dropped in three distinct steps: First 34 to 32, the down to 29, then 25! It stuck at 25ish for ~6 months and then finally hopped and crept back up to 29-30, where it’s been holding for the past few months. It appears that, the battery being charged all night for an extended period of time, the charging algorithm feared for loss of battery life and increased the “top margin” (i.e., stopped filling it as full).
Except here in FL, where it's the opposite. Those are the numbers I was seeing back in March when it was cool here. Now that it's hot, 32 miles is about as good as it gets. It's rare in the summer here to get over 5 miles/kWh. 4.7 is more typical. In the cooler part of the year that's more like your summer, I often get 5.8 miles/kWh.
Here in Austin TX, on our 2017, I’ve seen a long-term average of 4.6. I’m surprised you folks are seeing much more than that; I’m not at all an “aggressive” driver, and I use only moderate A/C (typically set at 78ish). Meanwhile, the Tesla Model 3, one of the more-efficient pure EVs, tops out at 4ish (in terms of long-term averages). I’m not seeing any really huge difference Summer vs. Winter, because ... “Winter? Oh yeah, I’ve heard of that; what a curious phenomenon!”
To clarify though, it’s hard to compare Model-3 EV-efficiency numbers to a Prius Prime’s. It has to haul around a monster battery pack, for example. Although, arguably at least, that’s just part of the efficiency equation. More importantly though, any pure EV has to road-trip on electric, which, being at high speeds, lowers their numbers. The Prime switches over to gas for road trips of any substantial distance, so our mile/KWh numbers aren’t penalized by as much cumulative wind resistance.
I got 61kms/38miles today (owned mine for 11 months). I'd hope to see the same result for next year. It is only an estimate and it depends how you drive it (it could be better or worse). Someone like to drive it as a stolen one
GOM is an estimate, but it takes into account of the past performances fairly closely. But even without any effort, GOM (and actual EV mileage) does increase with warmer temp. If you always drive heavy foot and pay no attention to how you drive, you don't get as much increase in GOM nor the actual EV mileage. I share PRIME with my wife, and every time she drives it, GOM decreases a bit. What I have not been able to figure out is the precise amount of the full charge in the traction battery that is used for EV drive. From various comments and data found in PC, this number falls somewhere between 5kWh to 6kWh out of 8.8kWh capacity battery, but depending on who you ask and how to get to that number, it varies.
For me, the Guesstimatron typically reads around 10% too high. Work is 19 miles away, but I need 21ish on the GoM to arrive there with zero remaining. However, it varies considerably depending upon how fast the commute flows. In the comparatively rare cases it’s a straight shot at 65MPH, it may take more like 23 on the GoM.
No kidding, when my wife drives it that number fluctuates like day and night.. don't even bother to tell her to flip EV/HV mode or she won't drive it On my way to work I get better mileage with some downhill. On the way home, some uphill so need a bit more of HV works. But in overall MPG, I am very satisfied as of today. Only seeing Gas Station every 3 weeks (84kms/53miles daily driving).
LOL... My wife drives our PRIME as two speed car. Stop or Go. I don't think she ever pays attention to the button for EV/HV switch. Here is the graph of daily GOM record in past three months. Can you tell when my wife drove the car?
I typically go to the gas station to put in a 2-3 gallons once every 2-3 months. That is, unless I have road tripping to do, of course. Unfortunately, I’m down to 81% EV now because I have had to do much more road tripping the past year than my historical 2-4 times per year. It was at something like 93% EV last year.
If my work place has a charging station, I should be in EV mode 24/7. Honda Clarity was my first choice but last year supply/demand and pricing issue, ended up with Prime. Seriously, no regret with my first Prius
Nop! She has no interest what so ever talking about a car. For her, a car is a box with wheels on it that takes her from point A to point B, and bigger the box happier she is. She use to drive Sienna minivan until we got rid of it last year. For a while we had only PRIME to drive between us, but finally we bought big enough SUV (used 2014 Nissan Pathfinder Hybrid) for her this past spring. Since Pathfinder makes less than half mpg of PRIME, whoever driving a longer distance that day takes PRIME. It is usually I, but occasionally when she has to go out of town, she drives PRIME.
Thankfully, we have 7 charging plugs at my workplace. Even better, they work in Austin Energy’s “Plug In EVerywhere” program: charge all you want at any ChargePoint station around town for $1 per week! I took a ride in a colleague’s Clarity PHEV last week. Nice car! However, the P.Prime is a considerably more efficient design, and (engineer, what can I say?!) I have a high appreciation for efficiency. Also, its engine kept kicking in in while nominally in EV mode, somewhat like a PiP; possibly for the equivalent reason (I’m not completely clear why).
