EV general discussion

Fisker - new jersey seems same temperature as uk atm , so little redemption there, but maybe Fisker cabin has a bigger heat capacity -
begs the question of which ev's have the best heat pumps/ insulation, to minimise winter vs summer range variation (whats the U value on a model3 roof)

e: VVVVV ok my bad meant rivian as simon remarked - hadn't looked back at prior page.
it's the cabin heating that is predominately impacting winter range though, in non-polar uk I thought

Mind blown.

Stop worrying about heating. The cars are heavy and need more energy to move. Why we on about fisker now? We were talking Rivian

You can turn heating off and weather impacts the battery chemistry to impact range anyway

I do roll my eyes when people say they preheat to save energy when the preheating comes from the grid they pay for. For me the benefit of preheating is getting the car at a nice temperature and defrosting windows etc. It’s not about saving the money or even maximising range. So even when not plugged in I would still preheat in winter.

Had one poster on a forum complaining they were only getting 160 miles of real range in winter but the GoM says 200 miles at 100%. It turned out they were preheating loads when not plugged in and doing quite a few short journeys. When I explained this all used energy that was depleting potential range, they just could not understand.

Don’t say roll eyes. You’ll offend someone.

Exactly as you said. It’s a comfort thing (and time saver on those frozen days) which I use on mine for cabin only (battery won’t preheat unless below 0C as VW realise preheating isn’t really that efficient on short trips). No point using 2kwh to just drive 10miles


The main benefit from experience seems to be enable fast charging. When using a Tesla and plugging in a supercharger and it preheats it really does kill the consumption Again it’s a convenience thing to save time.

the ability to precondition the car for me is a comfort thing for most of the time, and i dont even plug the car in when i am doing it.....

BUT in winter it is proper squeeky bum if i can make it to my folks in 1 go without charging, and in that case when going on a long road trip then the ability to pre prep the car from the mains is a real bonus. Personally i am not bothered arguing the toss on whether that is artificially inflating range figures or not, but if it means i can get to my destination without faffing about or being ripped off at public chargers, then every kwh counts.

I am, i take it personally that you are not bothered. Can someone please pre-condition my wokeness. :D

No-one said that in this thread, its just the usual "bullies" who should be rescueing poorly performing British marques. And the statement isn't totally wrong - they are saving energy in the battery to "go further" in their tin can.

Efficiency in EVs shouldn't be tied to "mpg" anyway. Dinorwig loses 3kwh for every 1kwh it makes, but its irrelevant because it is net-beneficial to the overall picture.

I don't give a damn about range or efficiency in my EV because I can just plug it in each evening and consume kilowatts that would be wasted otherwise. And its always "full" vs. jumping into the Merc and its on fumes and needs a visit to the petrol station.

No one needs full range in a day so its a moot point to suit the narrative you have already decided. 'bullies;' give me a break, use the word or dont, flirting with "" does nothing.

Point still stands, no ifs, buts or maybes about subjective views of something thats objective data. Dont get upset on a computer forum if people chase statement of fact over opinioneering.

PS. Best profits since 2015, Mums pension is safe. Chill out. :p Keen to understand the use of plural to in your statement of conjecture whilst you are throwing words around.

Ironically ICDP wasn’t talking about anyone in this thread either from what I can read

Not really sure anyone has done anything but read what’s it’s front. You seem to be using knowledge of a persons background now

Yes summer the batteries are warmer and less resistance so go further. And being as all people care about seems to be range then it’s of interest to most. Both you and I have a EV and ICE so EV is always gonna be cheap without analysing every % or penny. YOLO.

Anyway your house is gonna burn down with that 3 pin:)

He literally said the calc doesn't take into account preconditioning and then everyone jumped down his throat saying HOW DARE YOU NOT TAKE IT INTO ACCOUNT like he programmed the bloody odometer :cry:

Exactly so everyone was on same page until he said it makes no difference. It would double the energy used on a 8miles trip.


However I challenge the point of it really still. Doesn’t help ownership costs or carbon reduction. But makes better charge speeds.

I do hate the use of ellipsis. Have you finished your sentence or waiting for us to finish the piece of the sentence you didn’t want to write?

Just be clear what you are trying to say.

We have incorrect use of ellipsis.

And the word literally followed by a sentence which was never written. ‘Literally’ is the most incorrectly used word in the English language in recent times.

Anyone seen a ora cat?

Or any ‘anti-energy’ (isn’t this regen)?

time is money - unless you have mobile office capability in your car ? plus reducing throughput on the public chargers.

like I said in my update I thought car cabin heating was the main impact on winter 'efficiency' - in penfolds case anyway,
so returning to ev's who has the most efficient heating/insulation setup, with least kwh overhead.
