Charging an EV on a Cross Country Road Trip
marko:
So putting aside the terrible lack of investment in charging infrastructure, let's imagine for a moment that that was all great...
Electric vehicles are being pushed as the the way forward, and at the moment, they're all new sparkly, lights everywhere, modern and in most cases attractive, but, the burning question for me, is, how long do they last? You could buy a well looked after diesel vehicle that's eight to ten years old and still get another, five years or so out of it. Surely, after eight to ten years, the batteries in an EV would be wasted, rendering it in reality, scrap value only? Is that a whole new industry ready to boom dealing with all those batteries?
What's the answer? An end to private vehicle ownership and we all shift to leasing? Gonna put a lot of people off the road, right?

As for charging, my idea? Ditch the pump style plug in chargers and place some kind of qi charging strip in every street, everywhere. They do it for fibre, so why not? Then all the vehicle manufacturers use the same standard, and, whenever you park at the side of the road, a contract drops from under the vehicle, and charging commences. Tadaa. Guessing it won't happen as it would be hard to make profitable though I still think it's a great idea

I think that's a bit pessimistic. Typically lithium batteries are quoted as having 3000-6000 charge/discharge cycles. My car has a nominal range of 190 miles, at 12,000 miles a year that's 67 cycles a year or 44 years at 3000 cycles. Lion batteries do deteriorate with age, but that's a bit of an unknown.
The Nissan Leaf has been available for over 10 years and they still seem to be usable albeit with a reduced range; they didn't have particularly good battery management so more modern cars should be better. My Hyundai has an 8 year warranty on the battery, so I'd think the makers are reasonably confident there won't be many issues.
As to charging de facto standards have developed. In Europe it's the CCS connector (and Tesla connector); you can now use a CCS connector with a Tesla charger and vice versa. In the US it's the SAE J1772 (and Tesla). The chargers are high voltage and high current so installing distributed charging on every street is likely to be disruptive and expensive.

In the U.S., for fast DC charging, the CCS connector is also used. But Europe uses CCS-Type 2 and the U.S. uses CCS-Type 1.
So many standards to choose from.
The picture here shows the different types:

In spite of all the challenges, I think that EV's are the future if we want to address global warming.
Plus ... they're cool. Much more quiet and smooth. And sparkly lights.
