Not an entirely good article, they've missed out an important factor, that almost all e-car cells are large and low density, greatly reducing stress in all circumstances. Tesla's original roadster had high density cells so did suffer, but no others have made that mistake.

The article ended on the right note though, consider the battery will last as long as the car.

For most owners that will be true, ten years or more. For those wanting to keep one longer, we won't all need the guaranteed 75% capacity at 8 years old, especially given the huge number of ultra rapid chargers there'll be in eight years time.
.
Salient point was though flecc. if you run lithium battery to zero from 100% its good for 500cycles.whereas if you run it from 90 to 20% it seems good for thousands. That point wasnt made when I purchased ebike. They said each charge counts equally... (ie put 50% in and its half a cycle used)
First time I, ve seen it written down but suspected similar.

Red bus anyone?

Figures from a House of Commons library document puts the UK's net contribution to the European Union and European Commission budget since 1973 at around £177 billion.

By contrast the expected hit is estimated by Bloomberg to cost £200 billion by the end of the year - with a £130 billion hit having impacted the economy before Brexit has even happened.

The analysis by Dan Hanson, a UK economist for Bloomberg economics, expects Brexit uncertainty to continue to take a toll on companies and consumers by the end of the year.

And while the expert predicts that tax cuts and increased borrowing in the forthcoming budget will give a "growth spurt", they predict it will be a "one off" which will be unable to make up for ground lost since the EU referendum."

Experts? who needs 'em, when we can sell up and become an American Colony?

The Amazing Dr Fox has emerged to find "Reds" (sorry Blues) under the beds

Brexit risks being sabotaged by meddling pro-EU civil servants – Dr Fox’s warning to Boris
BORIS JOHNSON must carry out a sweeping overhaul of the Civil Service to stop pro-Brussels mandarins from sabotaging Brexit, senior Tory Liam Fox warns. In a speech to a Westminster think tank, the former Cabinet minister will say many Whitehall chiefs remain determined to keep the UK as closely tied to the EU as possible after the departure from the bloc at the end of the month.

Perhaps they are trying to save something from this train wreck?
Just a reality check
In actual fact the Civil Service organise and run the country, always have, and have the experience to do so.

Fox and co are the "meddlers" and possess neither the skill or intention of doing other than interfere to promote lobby group agendas paid for outside this country, and they still have no plan worthy of the name

I can't see that happen.
The Civil Service is staffed but much more capable brains than the whole of the tory party put together.

We see a lot of those around here too, mostly Amazon hires, but as they are all newer than 16-plate and Euro6 no smoke is seen.
Lots of the older vans are approaching antique! Mind, some will be petrol.

But I have never knowingly seen any vehicle stopped for smoke.

Back an awful lot of years, I think it was Tomorrow's World had a piece about identifying dirty exhausts from the side of the road. I think it was some fancy optical device but I could be very wrong about that. Made it sound as if every dirty vehicle was going to be identified and taken off the road within weeks.

If I were a senior civil servant, especially if approaching reasonable retirement age or with alternative prospects, "leave them to it" would be echoing round my brain.

Of course, there might be ethical and moral issues about doing so, as well as emotional.

I was reading something about computer lithium batteries recently where the view was very much to add the percentage charges up. (Think it was Apple, but might have been archive rather than current.)

But many computers and phones do their damnedest to avoid both absolute flattening and 100% charging (or at least, not repeatedly charging the last few percent).

If the 90 to 20 range is all that is sensible to use, it might be better to re-classify batteries to only 70% rated capacity.

With GBP on the slide, again. Petrol up to 129.9. (I paid just 119.9 recently so that is a huge increase.)

to be fair, manufacturers give plenty of sensible information on how to make the most of their products. The capacity that you see advertised are real, the danger zone is above 4.2V and below 3V for Lithium ion batteries, beyond the recommended operating zone and the advertised capacity excludes those extreme ends.
Their guaranteed capacity and charging cycles are usually on the cautious side.
If you can moderate the current then you can extend the life of the battery well beyond the guideline.

VW are claiming 8 years/100,000 miles on current Golf. Not sure what they are limiting battery to but it must be of order 85 to 25% as in most recent test it only managed 150 miles. (claimed 186)
Screenshot_20200114_082854_com.opera.browser.jpg

I, m afraid for my use that rules even Golf out. ( most frequent journey to coast and back of 160 miles)
They must get it to 200 miles to be feasible for most of us. Even folk who do 30 mile journeys in week want capability of a trip out at weeekend.???
Test quote is from 2019 Autocar test of Golf. Highest spec.By Matt Prior.
And it was a good day, good conditions. Throw in rain, a couple of stops and real world range is soon 130 miles???

I think VW were going on about having three battery capacities with the largest having about double the potential range. But everything appears to be mentioning/promising the highest range but only even tentatively offering the shortest.

(Not that they don't say that but you do have to read carefully. Headlines alone would have you driving the length of the A40 in one charge.)

Good news Woosh! approaching 800 miles now on my new "Big Bear" it has the 17.5 AH battery, I charge it every 50 miles with an indicated 25% left on the control display, using power level 2, Never use the throttle.
Not entirely sure how long it takes to charge as I charge it overnight.

I'm looking forward to significant numbers of electric vans. We seem to have a disporportionately high number of vans round here - of the generally Transit type as well as untold VW transporters and the like. Will be delighted to see fewer of their blackly smoking exhausts.
That needs the local authorities to give them a boost. In London we've now got the odd areas where no ic van deliveries are allowed, thus pushingcompanies to buy e-vans.

Will probably end up with us getting even more old, decrepit, smoking vans down here... :(

Have to be fair to the council here, they have quite a few charging bays in their car park.

Far more than double, it's 125 miles, 220 miles and 320 miles for the three prices on their new ID.3 model, which will replace the e-Golf.

This is a sensible policy a number are following now, since many people never do long runs. Some only ever drive very locally so are never far from their home charger., so no point in forking out for even an average size battery.

But for virtually all e-car owners it's not relevant. Most rarely use anything like all the available battery capacity in their normal use, and as the article says, the cars have plenty of protected reserve that's not available, so they can't empty them.

And as I said, e-cars don't use the high density high stress cells that e-bikes use.

The fact is that the batteries are lasting far longer than was expected, hence the three increases in warranty length.

Boris Johnson says public can 'bung a bob for a Big Ben bong'
Following calls from arch-Leave MP Mark Francois to strike the bell at 11pm on January 31, the prime minister said the government is working up a plan for people to contribute to the costs.

The House of Commons Commission earlier agreed that the estimated cost of refurbishing the tower for the sake of one occasion was hard to justify.

Johnson told the BBC: "The bongs cost £500,000 but we're working up a plan so people can bung a bob for a Big Ben bong because there are some people who want to," he said.

"Because Big Ben is being refurbished, they seem to have taken the clapper away, so we need to restore the clapper in order to bong Big Ben on Brexit night.

"And that is expensive, so we're looking at whether the public can fund it."

My tweet was "surely there must be some Russian Oligarch willing to give a "bung" to celebrate their victory with a bong?"

FRom the Independent
https://www.independent.co.uk/news/uk/politics/boris-johnson-iran-nuclear-trump-deal-soleimani-death-a9282686.html

The Iran nuclear agreement should be scrapped and replaced with a superior “Trump deal”, Boris Johnson has said – as he shrugged off being shut out of the decision to assassinate Qassem Soleimani.

Appearing to sign the death knell for Joint Comprehensive Plan of Action (JCPOA) – backed by the EU – the prime minister instead heaped praise on the US president’s negotiating skills.


“From the American perspective, it’s a flawed agreement, it expires, plus it was negotiated by President Obama – from their point of view it has many, many faults,” Mr Johnson said.

Boris is Grovelling already to his new master!
Another Great deal on the way. like the one with Kim Jong Un?

It is a sensible option, I agree.

It would be especially good if you could buy the small battery and hire an additional battery to upgrade to medium or large on an ad hoc basis. (Obviously, that would depend on it being straightforward enough to slot a second/third battery in.)
