The Thing about EV charging capacity is it is all relative to how long your stay is. Show up to a campsite with a 120V AC standard wall outlet, it might take you 60 - 100 hours to get a 100% charge, really not a big deal if you are camping for 4-7 days. If you are only gone for 2-3 days hopefully you aren't going so far as to use up all of your range getting there, so maybe it only takes 30-40 hours to charge on that outlet.
I don't know if true, but I've heard of people trying to find ways to get 660V for charging into residential garages. a 480V is going to get your vehicle charges in 6 -10 hours depending on the battery. Plenty of time to plug it in every night if need be.
The service station ones, absolutely, we need to get 660V 3ph DC on them, we need to consistently be getting 150+KW out of them (right now most of the ones in Alberta are rated at 500KW and operate between 25 KW & the high 40s, they are taking 1-2 hours to charge, get up to 150, get down to 30-40 minute stops and we are getting into a realistic use case).
Serviced Rv campgrounds generally offer 50 amp service. Isn't that what home chargers would run at?

Do you mean 3 wire DC? No such thing as 3 phase DC

Not sure about 50 amps at campgrounds?, But if I plug my car into a 15 amp wall on empty it would be full in ~60 hours / 2.5 days. So whatever an ERV looks like, a 7 day camping trip on 15 amps should give it enough juice to get it back where it came from. At home we plug our car into a 50amp 240, and it would take about 8 hours from ~5% up to 100%, but that also requires a wall mounted charging unit I had to buy for $800. The one that came with the car is just for 120V plugs.

I'm firmly in favor of moving away from fossil fuels as quickly as possible, but this documentary gave me some things to think about. The extraction of rare earth minerals creates serious problems, and these problems are only expected to get worse in the coming decades. Hopefully we can get a discussion going on this.
Will technological advancements get us, within a reasonable timeframe, to a point where rare earth minerals are not required for green energy? I'm not convinced.
Hey everyone, our Minister of Environment is attempting to include nuclear energy as a “sin stock” so that it may not be funded as a clean technology by Green Bonds. This is counter to the EU’s inclusion of nuclear in their Green Taxonomy, and even what he said at COP this year in Glasgow.
Boris Johnson has shelved plans to double or even treble the number of wind turbines in the countryside and approve plans for up to seven new nuclear reactors instead. The Prime Minister is said to have rejected ambitious targets presented by Business Secretary Kwasi Kwarteng to double the UK's onshore output to 30GW by 2030. Instead, Tory opposition in the party's shire England heartlands and within the Cabinet means that new atomic power sites in rural areas are likely to get Government backing.
The reality of energy security starting to set in across Europe. Belgium too has reversed their nuclear phase out, and instead will be extending it's nuclear program by 10 years. France, already pretty nuclear heavy, recently announced a new nuclear push with up to 14 new reactors, as well as a fleet of small-scale plants.
You're up, Germany.

It takes a long while to build nuclear - so if this just becomes a typical political flip-flop issue where they flip from wind to nuclear to solar to whatever else - they better start building ASAP.

Raw material and logistics inflation coupled with downward price pressures from auctions have led to an unsustainable situation where wind OEMs are selling at a loss, with the sector unable to deliver Europe's planned tripling of wind capacity by 2030, industry leaders have warned.
Quote:
“The state of the supply chain is ultimately unhealthy right now,” GE Renewable Energy chief executive for onshore wind, Sheri Hickok, told a panel at the WindEurope 2022 conference in Bilbao on Tuesday.
“It is unhealthy because we have an inflationary market that is beyond what anybody anticipated even last year. Steel is going up three times.”
Steel for offshore wind towers is currently being purchased at over $2,000 per tonne, Hickok gave as example, adding that the prices of copper, carbon and logistics had also soared.
“It is really ridiculous to think how we can sustain a supply chain in a growing industry with these kind of pressures.”
After hefty price hikes last year in the wake of the Covid-19 pandemic “things were higher but stabilising,” Hickok said, but added that with Russia’s war in Ukraine, the entire system had “unhinched” again in the past eight weeks, making it unsustainable at an unprecedented level of uncertainty.
Quote:
Enercon’s new chief executive Jürgen Zeschky went even further, saying “all European onshore OEMs are in trouble.”
Over the past eight years, cost was the only driver for developments, with low levelised costs of energy and low turbine prices driving the whole business, he told WindEurope 2022.
“We have reached a low cost base, but at the price of outsourcing to low-cost countries,” Zeschky admitted.
“If you look at Europe and Germany, we are constantly losing jobs in industry by relocating to other places.”
But the situation has changed fundamentally, he pointed out.

BILLINGS, Mont. (AP) — A subsidiary of one of the largest U.S. providers of renewable energy pleaded guilty to criminal charges and was ordered to pay over $8 million in fines and restitution after at least 150 eagles were killed at its wind farms in eight states, federal prosecutors said Wednesday.
NextEra Energy subsidiary ESI Energy was also sentenced to five years probation after being charged with three counts of violating the Migratory Bird Treaty Act during a court appearance in Cheyenne, Wyoming. The charges arose from the deaths of nine eagles at three wind farms in Wyoming and New Mexico.
In addition to those deaths, the company acknowledged the deaths of golden and bald eagles at 50 wind farms affiliated with ESI and NextEra since 2012, prosecutors said. Birds were killed in eight states: Wyoming, California, New Mexico, North Dakota, Colorado, Michigan, Arizona and Illinois.

Haven't read the whole thread, so apologies if this has already been posted or discussed:
The fleet idea makes a lot of sense, and the stations feeding back to the grid depending on prices.
I wonder if the long-term solution could be a dual model:
1. primary battery that works by charging - but it could become much smaller/lighter if it only needs to do more typical daily ranges (perhaps finding a better sweet spot of a weight to range ratio)...and bringing the costs down overall.
2. modular 'expansion' batteries available at charging stations (primary battery could also charge during the swap)
Obviously lots of other considerations (tuning a car to drive well at two very different weights), but I could see this easing consumer anxiety about having all the eggs in one big-ass expensive battery, and mitigate against degradation issues with the primary battery.
This might also let consumers right-size the vehicle to their needs. Does it make sense to pay upfront for and haul around an extra 500+ lbs of battery that you may only actually utilize a few times a year? It would also mean better allocation of raw battery materials.
And as battery tech improves, older generation EV's can get a bit of an upgrade with newer gen modular batteries - which may not be appealing to automakers in the long-run, but it could do a lot for re-sale value (it will be really interesting to see how the used EV market plays out).

So if anyone here who has been following my ranting about SMRs over the years is also an accredited investor interested in zero carbon synthetic chemical and fuel production, send me a private message. I’ve got a pretty interesting seed round to share with you.

There was some kind of government incentive involved?
That is remarkable? I am not familiar with Alberta solar rules, but here in Manitoba there is no incentive at the moment, but we expect one to get rolled out in 2022.
We have about 30k square feet of roof access that we could use as well, so keeping a close eye on this.

Have to think the car companies are a bit too "business savvy" (a.k.a. greedy) to allow for upgraded batteries to be compatible on older models... Nice thought though.
