Motorway speed power consumption

[monkeyhanger]

I have a simple worst case scenario I'd like your advice on

I'm getting a 58KWh Life Pro in a couple of months, my most regular journey of any distance will be 150 miles to London and back.

Will this car do this with 80% charge if I drive at 70-75mph on a cold\ wet winters night?

I'm beginning to think this will be a close run thing.

That will be a very close call. 90% charge? Almost certainly at 70mph.

It sounds like it will be close.

Not in relation to that scenario, really hot day, motorway/A road (up to 130km/h/81mph and 110km/h/69mph) in Italy, roundtrip distance 410km/256 miles, with the first and last 13km on windy country roads. Started at 94%, closed at 14% no charge on the road, so implied range 320 miles. About half the trip with air con, outbound single passenger, return three adults and a bit of luggage.

I'm fairly chuffed with that performance.

All the best

This almost exact use case is why we ordered a Tour instead of a Max. 140 mile round trip in deepest winter might well leave me with an approximated 10 miles left in the Max’s battery, according to the worst case numbers. There is hardly any public charging availability between the two points (I checked). All it would take is an incident on the M40, and I might need rescuing. Bad times.

I get this is worst possible case, and I might have the only recorded case of extreme range anxiety without actually owning an EV, but I really don’t want the stress each time I go to do that journey.

So we decided on the Tour which gives us a reasonable margin and flexibility to go off original route to find a rapid charger should it be necessary.

YMMV of course, but I honestly think we made the right call there based on our needs.

UPDATE: I ran your numbers through my spreadsheet. You won’t be doing that journey successfully on 80% charge. Again bear in mind that my spreadsheet is very much worst case…

First - getting stuck in traffic actually improves your economy…

Second - I’ve done 3 Manchester to Hull journeys so far - mostly at 70 and I’m averaging 4 for those journeys.

But all in summer etc…

Though if there is somewhere reliable anywhere on the journey - a 5-10 min splash and dash would keep you easily in range.

I’ve just driven from westbury in Wiltshire to March in Cambridgeshire 190 miles driving time 4.05 hours 4.2 kw/mi.
I stopped at fleet for a comfort break and topped up for 10 minutes then on to the ionity chargers at Baldock for a full charge arrived with 205 miles range so just a comfort top up break on my return.
It’s not to cheapest way to do it but convenient.
Unless you have a good bladder 70 miles would need a break so my advice would be to top up while finding relief so no anxiety either way

It's going to be interesting. Looks like may be needing a quick stop at Reading or Chieveley services on occasion.

Thanks for the advice, I hadn't even considered that I might not make it until reading this thread

Not in winter if setting off at 80%.

You would get roughly 3 miles/kWh, possibly less, setting off at 80% with 3 miles/kWh you’re looking at 139.2 miles total.

Setting off at 100% and you should make it home, if not then a “splash and dash” stop on your way home would be needed.

Wait, you said motorway speeds, and then you start talking about Reading. You’ll probably be fine at M4 speeds

[BeesKnees]

True

I also forgot to consider that a third of the journey isn't on motorways so I'll be doing 40-50mph max.

I'm looking forward to finding out, but I suspect it's not going to be as bad as I feared

We've just done Dublin to Devon last weekend.

Was at 100% leaving home, drove motorway down to Rosslare and used ESB charger to get from about 30% to about 70%.

Off the ferry at Pembroke and we topped up at Cardiff West Moto Gridserve when we stopped for coffee. Went from about 30% again to about 70% again in around 20 minutes.

Down the M5 and we stopped at the Ionity at Cullompton. Was down to 23 miles of range at this stage, around 12% battery left. Charged at the Ionity back up to about 70% in about 20 minutes but cost a fortune compared to the other top ups.

Made it down to Tavistock with about 80 miles of range left.

Overall very happy with the journey, the Gridserve didn't want to charge 2 cars at a time but a guy with a Leaf very kindly let me go first even though he'd been there before me. It certainly helps to plan in advance, a combination of ZapMap and ABRP helped for sure.

Got the return journey to do this coming Tuesday. Car is saying I've a range of 240 miles at 100% charge, Cardiff is 150 miles away, considering trying a one stop approach this time...

I'm beginning to think this will be a close run thing.

I drove to Mersea (past Colchester) there and back from North London(via a pub for lunch:) ). It was a total of 155 miles and I started with 90% charge and was left with 21%.

I have just driven to Chester, it was 207 miles and and the car said 218 miles with 90%, so could have made it but stopped after 75 miles at the excellent moto rugby service- they have 30 chargers !!!

[CarterHounslow]

Rugby services is ridiculous, I've been there as it's not far from where my parent's live, and I was just curious. I imagine that's how many services will be in 5 years.

I just did long journeys to Kent and back, good weather, 3.5 average is best I could do, and that was only helped by some very slow moments around the M25. 3.7 is my long term average, which I'm pretty happy with as it's a mix of driving I do, city driving, motorway, A roads...

That's the funny thing. Traffic not only doesn't effect ID3 mileage, it can help if it keeps you below 60.
My mileage worries with ICE are totally not relevant anymore

We did the Devon to Dublin return yesterday.

Made it from Tavistock to Cardiff with 22% battery. Charged there back to 80%
That got us to Gorey and the Ionity chargers there at 11%. Charged up to 60% and that got us home with 25% remaining.

Very happy with how the long journey went. A half hour stop in Cardiff and 15 minutes in Gorey was pretty much what we'd have stopped normally.

[colonelpurple]

great journey. I feel that with a bit of planning for a mid-stop, especially on a modern motorway service station, its a breeze.
Its more tricky if you are off the beaten track, but if you are staying off the beaten track its easy with a granny charger

I'm trying to find a fast charging station around Sheffield/to Nottingham just off the M1 that is walkable from a Premier Inn. We have a Newcastle to Southampton drive soon and the kids like the unlimited breakfast (and I like the fact that kids eat free!) - so wanted to break the journey up, seems I'm out of luck after looking at all options on 3 Premier Inn/Beefeater between 150 and 200 miles from Newcastle on the way down. Nearest I can find is a mile walk away.

[MotMot]

There’s a new 120kw InstaVolt south of Sheffield - less than a mile from the M1. Perhaps a 20-30 min stop there is easier than a premier inn walk?

Can you PAYG with instavolt or do you have to join up? Trying to get at least 180 miles before needing to charge, because if I do that, I'll be able to get to Southampton on 1 charge rather than 2. If I can charge on 100kWh though, 130 miles done to Sheffield will have brought the car down to 40% (23kWh) how long for that charger to get another 23kWh in and get me to 80%? I'm guessing it'll average 50kWh charging speed, so about 25 mins?

I think it'd be better to get the battery lower than that by going further and getting a better charging rate by taking it from 10-15% back to 80% for not much additional time taken?

When picking up my car from down south and driving back to Newcastle, I relied upon the ID3s Nav to point out chargers to use and ended up with a BP pulse 50kWh unit around Catterick.

[MotMot]

Payg. 40p per kWh.

IV is easiest and most reliable network (in my experience and according to surveys).

They just work. Well.

[MotMot]

Tbh I’d see how you go. You never know how traffic may reduce consumption - or cold/wet weather may reduce…

And when you feel like a coffee/wee etc!
