EV Range of your car and from what % usage battery are you claiming it?

Oscar_Madison

Sorry- a long winded thread title - but I thought it does need spelling out a bit

So as a recent purchaser of an EV, my mind is now focused on all things “range”- simply because I’m in learning mode. But also because since we now have KW per 100kms consumption (which is a great universal statistic in fairness) vs battery size vs Summer/Winter - it’s very hard to determine what car is achieving what - but especially when it comes to “range”-

I see posters here saying - “I get X kms in winter from my Niro” or “z summer range from my ID3” etc

Great but…I can’t help but think you’re all coming from slightly different perspectives - are some of you stating your range is based on 100% charge down to say 10% charge where maybe others are 80-20%?

Is there a “my car does X range” standard reply that can be accepted to mean say 100-20% - would that work?

It’s especially pertinent to people who are considering an EV purchase for the first time- seeing some posters claiming say a Cupra Born generally does X kms per full charge while others or other websites it does Y kms can be quite confusing.

Anyone else think you have to clarify with posters what THEY mean by range? I know some state %charge to %Charge which does help but others just claim “I get X kms “

Before you go I'll throw the cat amongst the pigeons. I prefer to use km /KWh- which is equivalent to mpg. Currently I'm getting possibly 5.1/5.2 km / kWh. So in the Born my range on a full battery would be approx 300km.

Rolled into Birdhill last year on -3% and into Ballacolla last month on -1%.

No panic either time. If that was Mahon Point I'd be squirming a bit for sure.

It’s a statistic I’m keeping an eye on with my own car in fairness -as it’s new I’m trying to determine overall winter figures and then hopefully get much better summer figures - but shhhh, don’t tell anyone 😀

Thanks 👍

I've got good results from Regen on a hilly B road. Turn it off on the motorway. In urban driving I leave it on I've got used to the nearly one pedal driving.

Reminds me a bit of a post on a facebook ev group, I replied to. The poster drove 110km to a ski resort that was at 2000m elevation, starting at 100% charge and was flabbergasted to see only 75km range available when he arrived. It's not really a concern in this country but you can easily work out the effect of climbing mountains. He was blaming the 1.5 degree temperature drop, but in his case, the 2000m climb would have used 10kWh on top of the normal calculation for a 110km drive. Would have been exactly the same with an ICE of course and you'd get some of it back with regen on the return journey in an ev at least.

Really should be the efficiency unit..you know your battery size so can easily calculate expected range. How did the kwh/100km catch on? Legacy from the ICE days?

MojoMaker

Yep, to match the old litres per 100kms figures that some swore by.

Here's real life story from last week: I had to do a 500 km return trip on our i3 94Ah on Friday. Admittedly, I'm a over 10 year veteran of road tripping on EVs so not a noob by any means.

I started with less than full battery, which was kind of a rookie mistake, but it is what it is. Just meant I needed a charging session earlier than was ideal but there were loads of chargers on route so that was not a problem. The well used i3 seem do about 140km at 105km/h indicated (102km/h real speed) on wet weather conditions when the temperature is below 10 degC. The car has a pretty good size buffer below 0% indicated, unlike the old Nissan LEAFs I'm also used to, so I had almost no range anxiety when arriving at -2% SoC at Barrack Obama Plaza where I had already charged earlier that day so was pretty certain I won't have issues charging while at the same time having no way to go somewhere else. I absolutely needed to charge.

I had earlier charged to 96% at BOP, had 140 km return trip to my destination and back to BOP. The car claimed I had a 20 km buffer after setting off but based on the previous knowledge I guessed the buffer would be less in reality. I also had to "cold start" at my intermediate destination, which uses some extra juice. Anyway, throughout the journey as long as you keep the distance to empty at above the distance to charger figure from GPS you are good to go, and you can always reduce the speed if it looks like it's getting a bit too close for comfort.

So basically once you know your car's capabilities, and have more than one working charger on the final or intermediate destination, you can absolutely use the 100-0 as the range. The cars usually have a subtle way to indicate accurately when the end of the battery really is near, usually there is some sort of diminishing maximum power indication and one that goes down to near the end the turtle mode is imminent and then you can start to panic if you are more than 1km away from the charger :-) On the longer range EVs on road trips there is absolutely no reason to live dangerously. Usually if you have already covered say 400km on that charge you (well me at least) welcome a break at a charger.

You have a 60 kWh battery, the car does 20 kWh/100 km, you have 300 km of range. Simples.

i prefer to use 'km per nice long hot shower'.

for me a nice long hot shower is a shower lasting 10 minutes with the shower at the full 9kW. i.e. 1.5kWh of electricity.

so i get 10km per nice long hot shower.

km/kWh is the most direct and simple measure of your EV model efficiency and as you say gives you a quick overall range estimate. Equivalent of mpg for ICE cars which was easy for everyone to understand across the range of fuel sipper to fuel guzzler cars. I think in metric terms it could have been km/L but this never caught on for whatever reason.

MojoMaker

lol.

magicbastarder

i jest, but it's a good example of how much electricity is needed to heat water.

look at it this way - if leaving a kettle on for an hour uses 2kWh; and if my car gets 6km per kWh - my kettle instantaneously uses as much electricity as driving my 1.8 ton car at 12km/h.

I think in our house it's more like immersion tank per shower..😁

If someone is asking me range of my car, I give a number that covers from the battery being full to a point where I have about 10km's left to get to a charger. I've had cars with a usable 16kWh to a usable 57kWh so I find the using battery percentage as "when to charge" a bit rough.

When you've cars available with 97kWh batteries and people saying you absolutely must charge at 15% remaining their buffer is near enough the same as my former e-Ups full battery.

that's a lot of coffee that you'd have the kettle on for an hour for!

Or even simpler, 60 kWh battery car does 5km per Kwh, 300 kms approx range.. why divide and multiply when you can just multiply

It's whatever calculation is built in your head based on the previous experience. I would personally prefer Wh/km as it results in a nice big number as opposed to the decimals. The km/kWh results in even more decimals as the numbers are smaller.

eagerv

Doesn't really matter what you use, as long as all manufacturers use the same so will be easy for comparison.

Tesla use Wh/km which is basically the same as kWh/100kms, just a decimal point change. Think they also use km/Wh if you so wish.

My Nissan and Kia used kWh/100km.
I never looked to change the units so can’t confirm if they can or can’t be changed in the menu.

Could have sworn that you could change to km/Wh but just went out to check car and doesn't appear that you can.

2020 model 3 performance.

Left Belfast on Saturday night at 100% state of charge. Weather was non stop rain and 7 degrees. Drove non stop at 110kmh until Dublin airport then around 90kmh on the m50 to Dundrum. Collected kids from a birthday party then headed for portobello. Dropped 2 off there then back to Rathmines. Had 37% battery left.

Forget what the efficiency figure was but I worked out in percentage terms that I would have roughly 320 - 330 KMS range from 100 to zero.

MojoMaker

You'd be happy with that I think?

magicbastarder

how does that work out on actual consumption?

Gumbo

https://www.boards.ie/discussion/comment/124222891#Comment_124222891

My 2020 M3P long term consumption was 19.6 kWh/100km.

OP for me if I say my car has x range in winter & y in summer, I'm talking about what the car tells me it has when I charge it up fully. Now will I always get that? No but that's all dependent on a huge number of factors. That's the range that means something to me. Same way as my old diesel car used to have a range indicator & if I was talking about that, I'd always be referring to when I'd filled it up as that would be it's max range estimate.

WildWater

When asked what range I get, I just say 'it depends'. The simple truth is I don't know. I've never tried testing it out and since it is well enough for my needs, I don't really care. Thus, if pressed further, I just say the brochure range and then qualify it with, but you won't get that. Personally, I've no real interest in getting into range focused conversations as there are far too many variables.

When I'm in a conversation with someone who is genuinely interested in buying an EV, I focus the conversation on driving profile and the importance of getting a car that fits your profile without being annoyingly inconvenient. My profile is:

More than 90% of my daily usage falls in the 80% » 20% (in fact that vast majority would be 80% » ~ 50%).

~5% of my usage I charge to 100% beforehand but does not require en-route charging.

~2-3% of my usage requires en-route charging.

In 3 years of EV driving with more than 60k covered, only once did I arrive home at less that 10%, and that was a very respectable 8%. I'm on my second EV, and I could have bought one with more range but all that would be doing is pushing down my 2-3% figure to maybe 1-2%. Thus, once it was above my threshold, more range was not really a consideration.

Buying to suit my profile and inconvenience tolerances, completely eliminated range anxiety and that's why I don't really care what my range figure actually is. Charging anxiety is another matter. But I charge at home ~97% of the time and I know, or will research, what my charging options are.
