When will I see 47 miles EV?

[Dan Albrich]

MrFixIt- Yes, had that thought and thank you, I agree. I had an older killawatt laying around so tried to measure with that. It flipped the breaker trying to charge through the kill-a-watt. The one I have is old and plastic discolored so I likely just need a newer unit.

I also purchased an EVSE level 2 (portable) that desires a NEMA 14-50 plug which I'm working on getting an electrician to install. Anyway, that one has measurements.

As a data point, when it was colder here in E TN, my EV range was showing 39-41 miles.

Now that it’s warmed up a bit, it’s up to 45 EV miles per HondaLink.

Thanks for your note David. The only climate I use is to press ‘front’ when windshield fogs up. I keep the heat setting at 68 or lower. As soon as I get the front window clear I turn climate off. Western Oregon’s wet climate requires some defrost or whatever it’s called that clears front window.
Also when I run it, I turn down the fan. Then once window clear, turn climate off.

Anyway be it as it may, I need do something to see out the window. And where I live no such thing as choosing not to do it.

But yes, useful to know if this is why my range seems relatively low.

I bought the car 9/25/18- temps were warm. No defrost needed then. Best ev range was 48 miles.

If you got 48 miles, that means it should be fine. Make sure to pre-condition with the charger attached before you leave. It will help a lot since the car will be warmed and still @ 100% battery. It will take 30+ min on a level 1 charger if its cold outside though.

I bought a touring 10 days ago. I was getting 38 on full charge driving on eco mode. This increased to 43 today. Why I am not getting 47 as I live in Houston which is not that cold. Is this normal behavior with new car ? Any relation with the bulletin update ? My car is Oct 2018 made.

The car auto adjusts the range based on your last few drives. So its all based on your habits. If you are doing the "ideal" city driving @ 30mph avg then you'll get better range than stop/go traffic or highway driving. Also the heater uses a lot of energy so any use will reduce it quite a bit.

Even my HV range is affected now. Filled up over the weekend and range is just 300 HV. EV range has been 32-35. It better go up..

 

[Ram1234]

Can you give us some more info like speed, road conditions (city/hwy), temperature, driving style (lead foot vs sedate accel), how much heater/defroster, etc.?
And is that actual miles to 0m/2 bars or estimated on the display?
The most accurate measure of comparison will be how many miles you can go per kW but you have to have an EVSE that reports this or a Kilawatt hooked up to your Level 1 EVSE.

My commute is 22 miles each way = 44 total

Out of 44 miles I drive 24 on hwy (hwy59) with speed around 75miles/hr other 20 miles at around 45 miles/ hr.

Roads are not that great (mostly concrete)

I had the car for 12 days, It started with 38 miles with full charge, now it is 42 miles with full charge.

Range shows and actual miles driven on EV is almost same.

I am driving Econ only, temperatures at 50-75 F in last couples of days.

Using climate control at 68 F.

Why I am not getting 47 or more since Houston is warm place ?

Note: Using Level 1 charger came with car. Model is 2018 Touring.

The 75 mph wind-resistance and the air-conditioner are working against you.

We are getting about 28-32 miles on a full charge in the cold here in Minnesota. I'm looking forward to the warm and better mileage.

Same here in Vermont. Over Christmas I drove out to my daughter's in Kansas. Started with estimate of 29 miles. At her house I regularly got estimate of 36-39 miles. Decided I am not going to worry about it. My 2012 Prius Plugin was supposed to get 15 miles on EV. In the entire 6 years I owned it, it never showed more than an estimate of 11 miles. Most of the time it was 9 miles. (The heater ran off the ICE so that did not affect the estimated EV as much as the Clarity heater.)

The half of your drive at 75 mph is what’s keeping you from more HV estimated range. Try driving on the weekend at speeds 60 or under and at your temps I bet the range will go up (at least until you get back to that commute). Also, you might try not using the Climate Control and see if that gives you any improvement. At 50 F, I can stay comfortable with just preconditioning.
I found the AC was not that bad a range killer this last summer. The heater is. And Level 1 vs Level 2 EVSEs doesn’t make any difference in range Here the temps have been in the fifties and I’m still getting mid 50s estimated HV range by preconditioning and not using the heater. But my max speeds are under 60 on the local expressway.
And even if a small part of your commute has to be in HV, you’re still getting fantastic overall milage.

42 miles sounds like excellent range given your speed and 68 degrees.

 

[Ram1234]

Now it is showing 44 miles with full charge. Happy with this number( covers my full commute)

I am not an expert but looks like battery took 10 days to report this 44 mileage. Not much difference in other factors.

Initially 37 then 38 then 42 then 44. Hope it reach advertised 47 miles on full charge in Houston.

Mine went up from 39 to 45 miles! The dealer that delivered the car is located at 10 degrees F colder than me. That might have helped too.

Yeah its learning your driving patterns so the estimate gets better. If you drive it hard / crank the heater/AC for a few days it will drop quickly

So sounds like it was originally driven harder (test driving) and you are now more economical so its going back up.

Maybe history is even more important than temperature.

Last night I recharged my car after a 500 mile day of driving (full battery) following 2 previous 500 mile days on just one full battery.
When I left home in December my estimated mileage was about 29 miles on EV with a full battery. Last night when HL reported that charging had finished, the estimated EV mileage was 37. The temperature was about the same as when I left in December. The only difference was that most of my recent driving was long distance highway.

When I am home, most of my trips are quite short so there are lots of stops and starts. The terrain is hilly so there are also plenty of hill starts. I think that the Clarity leviathan doesn't mind hills if it is already moving along at a good pace, but I don't think it likes hauling its considerable bulk uphill out of a sitting position.

Well they go hand in hand. It doesn't reduce it just because its cold, but because its cold you'll end up using the heater so instead of going 10 miles with 10% battery it will take 20% (made up #s), so next time it will say you'll only be able to go 10 less miles.

 

[JKroll]

I'm in Indiana. Purchased our car in early Sept I think -- regularly got low/mid 50's in EV range. Lately sometimes only 35 to 40. Expecting it to drop more if it ever gets truly cold -- been a very mild winter so far.

Our "commutes" usually involve a good amount of interstate, and we make no effort to drive for economy.

same live in indianapolis. range has dropped to 40 now ... sometimes to 37

havent got service bulletins installed yet.

Holy Batman!! Another one does exist in this state!? lol I’m actually in Zionsville. A green touring, but my wife drives it 70% of the time and it is out on the road quite a lot all around the whole north side and Carmel. I have yet to see another in the wild here besides mine...you? Hello from a local!

 

[WindsorBoy]

I can lose at much as half of my expected range when the heat is on.

This time of year I'm driving with a winter coat on and I've found that setting the temperature to about 15C (60F) is quite comfortable and saves a lot of battery life.

Something about ambient temperature alone does seem to affect the estimated EV range. With no change in road conditions, area or style of driving, and no use of heater, I’ve documented the estimated EV range decreased by 10 miles as temps went down from 70s to 40s F and then back up 5 miles when we had two warmer weeks of temps in the 50s and 60s.
So I think it could be the cold affecting the battery chem/physics in that it doesn’t charge or deliver as much power when cold. (Just a WAG on my part; I don’t know much about electricity.) I’m pretty certain the only variable was temperature and it tracked well with the changes in the estimated EV range.
It’s fixing to get cold here and I will do one week in the 30s with nothing but preconditioning and document that reduction, and then I’ll start using the heater and report that reduction.

people use more heat in colder weather, which takes a toll on projected full charge mileage when Clarity calculates from past battery depletion rates

 

[Crota]

Learning driving patters, temperature, preconditioning, traffic, hills, use of regenerative breaking. A simple fact like do you park your car in the garage may also have an effect. The simple fact is there are so many variables to consider that go into calculating the EV range.

There is one way of increasing EV range though. I'm assuming all of us believe that we are easy on the accelerator, (its not a gas pedal) but if you are like me and was used to engine noise to determine how hard you are stepping on the accelerator, you maybe surprised how hard you are accelerating. A more accurate way would be to see how often you go past the 3rd and 4th tick in your power meter. (What would normally be 3,000 rpm or 4,000 rpm in ICE driven cars) Try to stay below 3,000 rpm unless merging onto a freeway and you may see your EV range improve.
