EV Range

With spring weather we're seeing 50+ EV mile range quite often these days. Winter was more like 40-44. Also our actual miles drives vs EV estimate are usually in our favor. Yesterday I drove 9 miles round trip for 6 miles of EV range use. This is pretty typical.

We are likely to have the worst EV performance in the winter. Each day my wife drives our son 24 miles round trip to school. Solar generation on our house roof is lowest in the winter. So we have the most miles driven, poorest battery behavior, and low solar production.

Spring and Fall will be best. High solar generation, good car battery behavior.

Summer should be pretty good but intense heat will impact both solar and car charge. However no school means the biggest miles traveled per day is gone all summer.

It will be interesting to plot all of this.

At any rate we've not had the ICE come on unless we leave town. So we drive for weeks on end without the ICE kicking on unless Honda decides to do some sort of self maintenance.
 
ICE has come on several times while in ECON mode. Always with plenty of miles left in EV. Sometimes while just starting out with full charge. Going to Honda dealer tomorrow for diagnostic.

Thanks for the energy usage for the heater and AC. Where did you find this info?

Just over the years looking at it. For power to move the vehicle at speed, the calculator at ecomodder is useful (just google ecomodder calculator). For heater and AC I am basing off of Chevy Volt electric heater and AC. There isn't much reason that they would be drastically different for Clarity PHEV. They both work the same way, heating coolant to heat the air, or typical AC. Wiki indicates a typical automobile will use 3 kw for AC. https://en.wikipedia.org/wiki/Automobile_air_conditioning

These numbers are approximations though, I don't know specifics for Clarity PHEV, they should be fine for order of magnitude though.

This was a daily occurrence for me during the winter. With temps below 0, even with the battery fully charged, the ICE would be on for most of my trip to work (only a couple of miles away). This was frustrating because I found that despite owning an EV (I bought it on Feb 1), I rarely could use the car in EV mode.

Once the temps warmed up (anything above 0F), I could go on EV though my range was still in the 20s. I have always used only ECON mode.

Now, I rarely use any gas and the ICE has not turned on in several weeks unless I'm on a long trip and am trying to save EV for off-highway use. With my range now in the 40s, I don't envision much ICE use at all.

Aren't you glad you have a Clarity vs one of the many other plugins with 25-30 EV range!

HariN, you have a believable HV range showing. How much gas have you put into the tank lately?
Click to expand...

I filled first time gas
2600 miles driven - mostly on EV
It was showing reasonable 88miles HV range with 4 bars gas left
5.2 gallons to full tank, used no ethanol gas(philips 66)
New HV range 1000 miles
Did anyone driven 100+ miles inHV mode and check range? Did it go to reasonable range?
Certainly Honda is not using correct algorithm for HV range.

Thanks. It was inevitable that you would join the rest of us in the Society of Infinite HV Range. No one has yet posted that it significantly came back down to reality and stayed there. However it seems that several consecutive HV trips without significant EV mode will temporarily reduce the HV range reported. But it will ultimately go back up as EV to HV ratio returns to what is normal for most of us (lots of EV).
Best guess is that the algorithm doesn’t separate out HV from EV miles.

My wife drives a 650 mile round trip every few weekends with roughly 300 miles of HV driving each way. The mileage does indeed come back to something reasonable - but during the 2 to 3 weeks of mostly EV driving between trips it creeps back up. I found out that she has been using HV charge mode a lot because at least on EV she has an idea of how far she can actually go when she is low on fuel.

Good news is I am consistently getting 60miles EV range in the spring time. I don’t need to use AC yet, with exception of few times. With this range I don’t need to use gas at all

I’ll see your 60 sir, and raise you 65.8 miles EV range.
This is my high water mark too, HariN. All local, mostly daytime, 75/25 city/hwy, 60 mph tops, no A/C or heat and moderate temps. So this is my theoretical max range with no non-motive drain on the battery. Just started having to use A/C, so this will certainly go down. And yes that’s an honest number with no one way downhills to fudge it. All driving is a loop to and from home. It also tracks with odometer readings within a mile.
Gonna be sorry to see it go down.
Haven’t bought gas in almost 3 months. Glad I put some Stabil in the tank.

Thanks, that is good to know. First time, I drove 100 mile in HV mode from dealer to my place. It was showing reasonable range until my first gas fill. It looks like the software need enough HV mode drive to calibrate for each gas fill. Also that ideally should be at highway speeds. I will test next time I need to go out of town

My EV range was 66 miles yesterday. Drove 18 miles with A/C on (set at 70 degrees on a 85 degree day) and came back with 48 miles left in EV range. This was in town driving. Don't know if I would actually get 66 miles because I plugged in afterwards but I think it's very possible, particularly if I didn't run the A/C.
 
I think the EPA range estimate is conservative on this bad boy (can't believe I even wrote that). If you drive within the speed limit, mostly around town between 30-60 mph, in Econ Mode, and avoid jack rabbit starts, 55 miles EV range is easy to attain. I haven't hit our hundreds yet (June-August in West Texas is pretty brutal) but even with full AC I expect 40 plus (based on a couple of 90 plus days already this spring). Afraid my summer will be you guys' winter...

Although we've seen some pretty low numbers from cold weather driving. I think the long answer is that that EPA numbers don't work well when batteries are going to be used in cars that are going to be used in temps from 0 to 100 F. Derating curves would be helpful for those that want that much detail.

I think that's more like a range of accuracy:

0-40F EV range less than EPA
40-90F EV range exceeds EPA estimates
90-110F EV range less than EPA

YMMV
 
I did several trips lately running ev out but have been poor with my record keeping. It was nice here in Texas yesterday ranging from 75-85F-ish. We took a trip from my home to Denny’s then Home Depot then my son’s school then to Southlake to look at the Model 3. Once we left my son’s school we had the ac on (72F) we took 75 (70mph) to I635 and took express lanes for 11 miles (75 mph) and once out were dropped to 65mph until we went back to surface streets I pulled into the parking garage with 2 miles of range left. I calculated I went right about 43 miles. I am extremely happy with that number for what the car is designed for. I then paid the flat rate $2 to charge at their ChargePoint and shoved 13.96 kWh into the pack (with some preconditioning to suck up more kWh to lower cost per kWh to 14.3 cents per kWh)
