When are you going fully electric?

yes, judging by the comments on the i-pace/trophy track conversion which have additional battery cooling to avoid throttling after sustained use, we would expect sports oriented ev's to have that, maybe the taycann already does (bmw & the like must be doing tear downs)
2nd hand market wiil be interesting if in additional to range you provide a dyno type result to show peak battery power is not reduced;
would be interesting if the car/ev would show you telematics for battery current delivered, and vehicle speed, at 10's of ms resolution.

This would be useful and even if not that level of detail, the battery state of health, peak power etc... Would make buying a used EV much easier than a used ICE where it's really hard to tell whether it's been treated well mechanically throughout it's life
 
You’d likely just be able to pull that info from the BMS from the OBD port.

Tesla’s report things like power limit and even how many KW has been charged via AC and a DC charger. All EVs report the actual capacity.
 
Day trip out yesterday so thought I’d see how I’d get on just charging when we stopped with dogs etc.

15mins at M5S Gloucester. Parked and an etron pulled up seconds after but he carried on as said wasn’t desperate. Then ID3 arrived and was happy to wait 10 for CCS. First time I used ecotrocity so was surprised space free and it worked ~43kW as I understand they have throttled them to improve CCS handshake.

2nd row of images is Sedgemoor, ID3 this time had beat me to the CCS so grabbed AC for 19mins of 11kW.

RETURN trip. Tried Gloucester M5 N but an MX-30 was just unplugging and EQC hooking up for 40mins so carried on to InstaVolt just off the motorway… at an empty Magnet carpark pretty much calculated enough to get home after 15mins of charging and dogs walked, McDonald’s round corner available but didn’t like this experience really.

Then on way dropped by Strensham to see if I could get an Ecotricty triple in one day, charger connector battered and it wouldn’t connected as the plug wasn’t secure, 4 attempts and it only start charging once whilse I was holding the connector home…. Stopped when let go. Amusingly the same MX-30 driver was there and came over to have a chat aswell.

Bad traffic at Bristol but it’s kinda of less of a stress in an EV as the energy consumption improves if anything with the lower speed so less stress there.

Interesting day, busier on the roads and amount of EVs but not too bad taking the ABC logic, always be charging… or chatting, not sure which!

Started the day on 100% and added those charges just to top up. Dog/bladder only reason to stop on the way there. Then at Tamworth MOTO stopped to try new 120kW gridserve/ecotricity charger as on free vend. Only managed 65kW for the 13 mins I was there starting 8% but it’s only been in a few days.

Anyway just wanted to share experience of probably my first beyond a full battery day.

3.1 is about right for an iPace, they are known for being pretty 'thirsty' compared to a Tesla or Korean car. But at the end of the day it's a big car with big wheels and not the most efficient drivetrain, your just not going to see 4+ miles/kwh at motorway speeds. It compares very similarly to an EQC or an eTron, the Model X is more efficient but they cost £LOL or have a smaller battery so don't actually go as far (75D cars).
 
Indeed in the same way an F Pace would use more fuel than a Hyundai Niro. Once it’s 30mins or so you do see it really start to get into its stride as battery and oil etc is all at temp. The gearbox with cold oil is a bit of a drag. Shame for short journeys you can’t just tell the cars you aren’t going far to save it the potential of warm up etc.

So much capacity at speed though, 70mph and light throttle and it takes off like the V8s. Effortless.

Had a couple of 3.3 and 3.4 journeys and a best of 3.6 the other day. Just need to avoid the short squirts of power that like anything drag average down. Brilliant all round car, even the wife is warming to it.
 
Ah I see! I usually get 4+ and only see in the 3's if I'm doing 80 or so on the motorways so was surprised to see it down there at 3.1 is all. My knowledge on different EVs is somewhat lacking of course.
 
Still room for improvement though, as I said, the (much) bigger Tesla Model X is materially more efficient. Better efficacy means you can use a smaller battery for the same range meaning you can build more cars with the same resources.

Reducing consumption can have a wide impact, reducing consumption from electronics (via that pesky EU regulation) has had as much of an impact on decarbonising the grid as introducing renewables.

Yes, bigger is exactly that, more air to shift out the way

Nope. If it's 2 tonnes and shaped like a bullet, it's probably going to be more efficient than one ton shaped like a brick.

And that's before you start to look at "noise" in the system, how efficiently it converts battery energy to motion going forward. Think platinum vs nickel in the AV world.
 
Yeah but it’s cars we are talking about not a page from a text book. It’s a shame there’s not a term for aero efficiency of a shape, we could maybe call it “coefficient of drag”... ;)

Honestly there more to this EV game than efficiency, quite a significant difference in many other attributes. Most effect the vehicle experience every single time you drive it.

As said. We are talking in context of a car. Cd and frontal area are key.
I’m not sure why it’s such a big topic. Everyone’s known for years big ICE cars use more fuel than smaller ones !
 
Seems Musk has canceled the Plaid+ …

Annoyed as went for it due to all that extra range. advisors have said all they can do is cancel and I have to get back in the queue for an alternate car. In addition, several upgrades and models have gone up on price since my first order so paying more ..

Could have at least honoured the upgrade costs which are the same per model..

rant aside looks like Musk and the 520 mile range car was just vapourware.

Seems that 0.28-0.29 is the CD for a lot of the popular EVs, expect the model 3 / S, which are far lower.

There's obviously more factors at play but I'm sure a lot of the EV youtubers must drive like grannies on long runs when reviewing efficiency.

I don't think the corsa e I've got is particularly efficient; if I set the cruise to 65mph on the motorway, it gets around 3.7-3.9m/kwh. Set it to 70 and its more like 3.1-3.3.

you could say it is more important now, as a likely indication of ev range at motorway speeds, and ... why you might want a saloon.
manufacturers could be obliged to disclose it/both so we could differentiate if the wltps are a product of good aero or efficient transmission.
can't see what CdA of an I-pace is - data table which ranks ev's for motorway range+other criteria http://johnhwman.free.fr/Divers/Comparatif_VE.pdf

thought this was a interesting real life ev review by a mechanic travelling around servicing ev's (lots of changing cabin filters in x', s's ...) - solid 200miles/practicality
