When are you going fully electric?

ok - 1750kg - I chose the 320d because blun had had that pre model 3.
so with an additional 450/700kg that the motor has to accelerate (e=mv^2) if you did drive the i4 in a sporty way, wonder how much the range is impacted,
which is another part of the ev's as sports cars equation; (I guess taycann/model3 drivers on the neurberg ring know the answer to this)

videos good - competent team , £900 with labour for a cell replace; I suppose with battery cooling system it becomes more involved.
Weight doesn’t have a significant impact on range, once you get it rolling it’s all about drag and frontal area in normal driving.
Fairly sure a Tesla pack is significantly more involved. Just getting the thing opened up is tricky without damaging it and only a whole module replacement is viable due to the cell format.

Its not that bad. Its certainly more complicated and you could just replace one of the 14 or 16 modules but since each module is made up of lots of cells you just disconnect the bad cell and put it back in the car. Eventually of course with too many bad cells you will need to start replacing modules but there are 7000 cells in total so disconnecting one cell only loses you 0.01% of your power/charge.

You can go posting stuff like that, all the people who are scared of BEV's will say it is faked like the moon landings.
At £900 after 120k miles you'd have spent way more on any ICE car for routine maintenance.
ergh - if you accelerate 700kg from 40->70mph it takes 0.1KW/hr, yes there maybe energy recovery when you brake -
so if you drive up favourite hairpinned country road (col de turini, say) and repeat that 800 times in your 80Kw/h car its empty
edit:
not sure if you thought my reply was ambiguous but I agree it is a good price - head gasket has cost me more, and, with a completely refurbbed battery pack to slot in you can imagine, even that charge dropping

He did say "normal driving". How many people drive up and down their favourite hairpin road 800 times without stopping?

Does spirited driving not affect ICE cars now?

Affects how a car drives and size/strength(and cost
) of other components like brakes, wheels, tyres etc and depends what % of driving is motorway. Will be good to see the efficiency specs of the iX. It's gonna be heavy as it's massive but how heavy vs a similar sized steel construction car. Shame about the i4 though, a sleek carbon construction design would be good. IMO 2125KG for a Model3 sized car is too heavy, another EV barge . Really like the iX but way too big - not something I would ever need or want. I like the design.

Wasn't replying to you at all, otherwise I would have quoted you, done that in the past a few times asking direct easy to answer questions and never got a reply so don't bother now. *shrug*
It just drags the argument back to 'but I can fill up the ICE car in 2 minutes when i've emptied it'

A full IPACE does more laps of the Ring than a full F-Type, ask Dale Lomas. Granted the average speed is probably higher on the F Type which will always mean more energy use.
Bi-Directional power flow on a BEV does have benefits! The speed you can cover ground without a mushy feeling throttle aswell as slip intervention on a BEV being faster and easier to control is quite something and enough to counter the additional weight. When batteries get lighter the difference is going to be incredible.
Doesn't quite work like that, the cells are in groups parallel strung and then in series to get the voltage to the operating window. Drop voltage and power drops but some power electronics will simple shut off.
So you cant disconnect a single cell, they are also welded to the busbar plates and potting compound at the bottom is a glue, so you only need to treat them as module lego bricks really. Model 3 pack just had 4 lengthways modules rather than model S across car, so theres only really 4 servicable lumps, the Leaf with the NEC modules is far easier in that regard, especially as its air cooled. The new 4680 cells Tesla are going to are fully glued into the body so serviceability goes out the window, in conjuction with the huge mega castings Tesla will be simply replacing cars... its no wonder they have got into insurance to offer the full service to customers.
The green stripes are working on the plates, I'm actively noticing way more EVs on the roads now. Especially things like the e-208, Corsa, Mii etc. which aren't obvious at first glance.
It will still be some way off before we get an EV. My wifes car is likely to stay with us for another 5 years or so and my employer tends to run company cars for a ridiculously long time so my Leon replacement is years off. That said I'm really looking forward to it when the time comes, unfortunately by then there will be no financial advantages left but I'm certain the driving style of an EV would suit me.
How long into the future do we think it will be before an EV can become an integrated part of your home energy use? Sucking up solar or cheap grid energy when it is available and dumping it back to your air/ground source heat pump or water heating when required? Or is that more likely to become a thing with dedicated batteries?

You not watched the video I linked to? Thats exactly what they did. Dropped the battery pack found the faulty cell and then just disconnected it from the module and it was all good to go again.
Granted future ones may well be much more difficult which is a shame.
After all, its basically 7000 18650 batteries connected together in series/parallel. Should be easy to make it so they can have faulty cells replaced. To have to replace 1 of 4 modules because one small 3.6v battery has failed is madness.
I must have jumped that bit too - I thought he just said tesla significantly reduced price for replacement packs to $14K and third parties would mend them for 1/4 of that.
I'd hoped to see the dismantling process like for the leaf, to see how they dealt with cooling;
but as johnny said, thought batteries were becoming structural, hence harder to extract cells.

I'm not sure disconnecting a cell counts as a repair to me, to keep it going a bit longer, agreed.
Its not but it fixed it. Without disconnecting that cell, the whole module is out. Thats one module down out of 14 and serious performance and range degradation if the car even works.
You could just buy a new module and put it in but that costs a lot more. Although new modules are only $1389 and $800 used and a whole complete battery is $12000.
Personally I would just remove the one cell if it was my car. Its like replacing your entire monitor because of one dead pixel. You would live it it until there were so many dead pixels that you replace the whole lot.

The labour will be as much as a new module anyway

You might be right there. But do you want to add to your $1300 labour charge by adding a $1300 module as well? Makes your bill $2600 for just one cell failing.
