And another good news story for EV's, but from the more extreme end.

Together In Electric Dreams: How Carbon Emissions Have Been Slashed At Quarry

All the transport stages have been electrified at this site, the world’s first electric quarry, at Skanska's Vikan Kross quarry outside Gothenburg, Sweden, where a combination of electric and hybrid Volvo CE vehicles have been used over a ten-week trial run by the two companies. The results have surpassed expectations: carbon emissions have been cut by 98%.

All of the electricity used by Skanska Sweden comes from renewable sources. The same site, before the trial, generated 8,700 kg carbon emissions a day; now, that figure is 166kg day. That the quarry is almost entirely emissions-free is significant news for the beleaguered construction industry, a heavy carbon emitter.

Volvo and Skanska go green with ‘emission-free’ quarry

Known as Electric Site, the project is taking place at Skanska’s Vikan Kross quarry near Gothenburg, Sweden, over a 10-week period. Three separate vehicles will marshal, transport and load material around the quarry site between the primary and secondary crushers. Volvo expects up to a 95 per cent reduction in carbon emissions and up to a 25 per cent reduction in total cost of operations.

“This is the first time that anything like this has been attempted in the quarrying industry and, if successful, Electric Site could serve as a blueprint for transforming the efficiency, safety and environmental impact of quarries around the world,” said Gunnar Hagman, CEO of Skanska Sweden.

Has there been any progress regarding your complaint(?) on this issue?

I can't say as I signed a non disclosure agreement.

I've been told (possibly on this thread) that battery life is extended considerably if the bottom 10% and top 20% is avoided, and also that batts shouldn't be charged to 100% unless they'll be used immediately (well, soon) as sitting at 100% is not compatible with maximising life cycles?

The unofficial bible says try not to go below 20% and above 80%. I read that as rapid charging because shoving electrons in at 3kW won't heat the battery up like 45kW will. Rapid charging is always choked off by the car at varying rates of charge depending on make and battery temperature when the charge starts.

I'm not an EV'er but I'm sure I've been told (possibly on this thread) that battery life is extended considerably if the bottom 10% and top 20% is avoided, and also that batts shouldn't be charged to 100% unless they'll be used immediately (well, soon) as sitting at 100% is not compatible with maximising life cycles?

Lithium Ion batteries don't like to be at low or high charges, so yes, leaving them in the bottom 10% or top 20% may not be ideal. But that was before there were loads on the road, and manufacturers have become more relaxed about how the batteries are treated in daily use. EG the Leaf charging to 80% on rapids, VW voiding your warranty if you rapid charged 3 times in a row - that's all going away. I think you only really need to think about it when going away on holiday or similar - leave it half charged.

Edit - Just pondering, but it also occurred to me that automotive batts might not be expected to last as many cycles as stationary batts since they are designed to deliver so much more 'punch'. EV's might ask for 50-100kW from the batts, something that is highly unlikely from a stationary batt of similar size.

Yep. Under a car is a touch environment, and the big pushes and pulls in power from/to the battery are also harsher than they'll experience in their next life. They'll likely last the lifetime of the car then have a nice easy life stationary.

Leaf Rapidgate - the solution to this, would be to add cooling. A software update could certainly make repeated rapid charging faster, but it'll do that by changing parameters like how hot cells are allowed to get before the charging gets throttled. Maybe Nissan realised they've been too cautious in protecting their batteries.

Round of applause for the I-Pace. :T

Jaguar I-PACE = #1 Vehicle (Not Just EV) in Netherlands in December 2018! Tesla Model S = #1 EV in 2018.

December had 6,232 plug-in vehicle registrations in the Netherlands, a four-fold increase compared to the same month last year and the market’s best month since December ’16. The sales total translates into a stratospheric 31% plug-in electric vehicle (PEV) share in December, pulling the 2018 PEV share to 6%, a great result, especially when we realise that BEVs represented 89% of PEV registrations in 2018 and 98% in December alone.

Of course, the higher taxation of expensive BEVs in 2019 is the major reason for this surge, but something tells me (ahem, Tesla Model 3 …) that this exponential growth is set to continue through 2019.

It's an impressive figure.

But.


Complete NL market new car sales for December 2018
https://www.marklines.com/en/statistics/flash_sales/salesfig_netherlands_2018

Total Dec 2018: 20,028 cars.
Total 2018: 443,812 cars.
Average monthly: 36,984 cars
Average monthly to end Nov: 38,525 cars

I wonder why December saw barely over half the number of new cars of an average month?

VW: 5,108 cars November, 901 cars December.
Tesla: 736 cars November, 2,214 cars December.

Have the figures been skewed by some kind of end-of-year tax change heavily in favour of EVs?

Or against?

Weird! I take it you didn't read the article, nor what I quoted.

Wouldn't a tax change against EVs have resulted in a sales fall...?

Yes, I did actually. And I went past where the article left off, by doing a little more research to see what the normal figures were, precisely because the numbers seemed low for a wealthy Western European country of that size.

Hence me asking why December was such a small month for new registrations, compared to both November and the rest of the year, with the exception of a big increase in a small proportion of the market. The same number of EVs that meant 30+% for December would have been ~15% if the rest of the market had remained constant.

Hi

Maybe a combination of the day that Xmas fell on this year impacting the length of the holiday period and people concentrating effort & expenditure on various forms of festive shopping and entertainment rather than worrying about taking delivery of a vehicle on a 2018 plate as opposed to waiting a while for one delivered in 2019 ....

What do you guys make of the Renault Kangoo EV, like this one on autotrader for a family vehicle?


Apart from the performance, which looks diabolical. That could easily take all the junk I'd need to take the kids anywhere, including a few bikes.
