Shuush, he thinks I take him seriously! :rotfl:

I laughed my backside off throughout 2018 at the ever more desperate attempts to divide and divert this thread/topic. So far based on 2019, I'm gonna pop a rib.

Take the two letters "EV" away, and you've exactly described what I posted

That's going down in history.

Was that the discussion over putting a generator into a trailer to fast-recharge at the same time as driving?

I didn't claim it was impossible. I simply did the sums as to the generator output required, and pointed to the size of generator required. There was some disagreement, most of which ignored the "at the same time" bit.

And we all spotted that the generator you said was necessary was enormous and weighed several tonnes, then Z pointed out that the generator (range extender) that BMW were using was actually really small, and I pointed to the same unit in the W15 pick up truck, then there's a similar unit in the new London cabs (volvo 3cyl I believe) etc. etc. etc..

And to be clear, these range extenders are 'at the same time', they simply charge the battery for immediate use rather than power the motor directly.

We've been over this many times before - when you are in a hole, stop digging!

Hi

So in a position where overall automotive sales seem to be falling in Europe, particularly noteable in the higher specification sector, both the market penetration percentage and number of vehicles sold on a year over year basis for EVs seems to be bucking the trend and showing significant growth ?? ...

<Thinking aloud> ... Wonder what's the root cause behind that then? ...

HTH

Worth repeating that the TM3 topped EV sales in Germany in Feb, despite only being on sale from the 13th.


And, just for a laugh, do I win a prize?

Finally, yes - no real surprise there. Production is still way behind the projections (we appear to have finally hit a sustainable 6k, with a couple of 8k peaks), though. It'll be interesting to see the Q1 production totals in a couple of weeks, then the Q1 financials a month later. Has the corner turned? Or were the profitable quarters freaks down to book-massaging?

On that subject, perhaps also brace yourself for more FUD and BS in the next quarter report, as Tesla will see a large hike in their 'in transit' figures for the TM3 as they start to sell in China and Europe. Unless of course, they carefully stagger sales/deliveries off-continent to avoid the last few weeks of each quarter, just to keep the FUD'ers quiet.

Hiya, bet you think you went way OTT, but wait till Tesla announce a loss for Q1 (and possibly Q2), as they switch to worldwide distribution of the TM3, restructure, and invest/expand in China.

It's all getting a bit too predictable and boring now as we enter a third calendar year of FUD, BS and border line trolling. And I'm still waiting for the Tesla like attacks on VW for their failure to deliver anything like the number of BEV's they suggested?

One companies solution to petrol (and patrol!) stations:

Park up and plug in: Plans unveiled for 100 'electric forecourts' across UK

Alongside charging availability for private cars, the Forecourts will have reserved parking zones for fleets, taxis, delivery vehicles and heavy goods vehicles.

Most vehicles will use rapid charges that can deliver an 80 per cent charge in under 30 minutes. A coffee shop, convenience store and lounge with high speed internet will be available for use while drivers wait, in what Gridserve is touting as a "new and compelling customer-focussed charging experience".

And today's 'thought from the shower' - my brain did some mathematical gymnastics and reminded me that the Tesla semi is to charge at approx 1.6MW, based on adding 400 miles (800kWh) in 30 mins.

That made me think about the V3 supercharger upgrade to 250kW, and a dedicated 1MW charger for every 4 bays/cables. So sort of similar to 4 400kW connectors (as the semi mules shown at the launch have 4 ports).

Also if the 60(ish)kWh TM3 can take 250kW, then 1,000kWh taking 1,600kW's is actually a 'gentler' ratio. And could be maintained for longer, whereas the car batts can only take that charge rate when mostly discharged and only for the first 5-10mins.

I appreciate this is a nothing post, just thinking out loud, but thought I'd mention how some more jigsaw pieces seem to be slotting into place, especially as some (going back) had concerns over the ability of chargers, batts and cables being able to handle these high loads.

Charging stations with cafe and internet work for me. Means I can get half an hours admin done over a coffee whilst doing the road warrior thing.

Did that Leaf (if i remember correctly) issue regarding overheating on constant run/charge cycles get resolved?

Makes a lot of sense; if people can get enough charge in 30 minutes - make a profit by selling them coffee and so on at the same time. Pick the right locations on motorways and trunk routes with space for enough chargers (ideally with the most common connectors) and it should work. City or suburban versions might struggle because the land costs per charging point will be higher.

Half of the petrol stations near me have a convenience store attached anyway - so they could probably add one or two chargers to their existing parking spaces as an incentive as long as they can stop them being blocked by lazy/inconsiderate idiots - perhaps a rising barrier that you can drop with a code issued when you booked ahead on the app? Where's the point that the capital cost of that installation is covered by the extra revenue of attracting more EV drivers - that's the question?

Yes and no. There's a software fix but even on the new 62(?)kWh battery version there's only a bit of air cooling. Problem is, if they've allowed the battery to charge faster, will it degrade quicker too?

Pleased I got rid and have a 64kWh Hyundai Kona that has a proper battery temperature management system.

BP and Shell are starting to buy into BEV charging so I suspect forecourts will continue almost as they are now but with electricity being supplied as well as fossil fuels.

They might have space to add one or two charge points - but not the 20 plus the article refers to. Especially when the average time each customer spends taking up a charge point is considerably more than at pump - I can go from 5 miles range to 400 miles range in under 5 minutes with a petrol pump - the best chargers can't match that yet. So the coffee will have to be really expensive to cover the additional cost of expansion.
