> NMC does have an increased fire and thermal runaway risk
> The USA has put regulations and restrictions in place to make sure certain sources of Cobalt and other minerals are not used in future supplies and designs. Estimates show that there will be a Cobalt shortage by 2028, which has been quickened by the increased use of Cobalt in electric vehicles and battery energy storage designs
> NMC has increased energy density with a cycle life span that is geared towards a reduced number of cycles per year.
> The full charge and discharge cycle of the LFP battery will only decay to 80% of the original after the number of full charge and discharge cycles is greater than 3500 times. … The charge-discharge cycle life of NMC battery is about 1000 times.
Now it's a cobalt shortage. Most of these "shortages" ignore what can happen when prices rise and/or are regulatory shortages rather than actual shortages.
When folks talk about cycle life being limited, the cobalt and other items may be re-usable after in a new battery production. A 6c is an insane charge rate. There may be cases where the cost / benefit works for something like this if they can deliver.
The common hiccup in many battery stories is just the lab theory -> production reality curve. It's one thing to have a solid state battery that charges in seconds on a lab bench doing 1 picowatthour and another to have 1 megawatthour of storage.
The trade-offs you list are real, but we already have data showing NMC batteries lasting many miles (1,000 cycles at 250 miles per cycle is a long way) and fire risks of EVs have already been shown to be many times less than ICE vehicles.
If you put fast chargers at places people already go today, you don't need gas stations outside of travel routes.
EV chargers belong in gigantic parking lots. So shopping centers and office complexes. The great thing about putting chargers in these locations is that they are both often close to highways, are places that people regularly visit, and they have complimentary usage hours (offices are empty when shopping centers are full, and vice versa).
At least in California there is now often a glut of solar power during the day when presumably a lot of cars are parked at peoples workplaces.
For places like Bucees (which is basically a small grocery store in size), 20 minute charges are pretty reasonable. By the time you walk to the store, use the bathroom, browse the goods, and stand in line for checkout, you're easily near 20 minutes. If anything, it seems beneficial for a place like Bucees since you're incentivized to spend a bit more time browsing and buying stuff.
I feel zero range anxiety in my Tesla when I'm in Austin, Houston, or Dallas. When I drive to somewhere like Galveston that has 0 superchargers, I feel anxiety because there's not one around if I need it.
However I do completely agree that a 10m full charge time could be a game changer for increasing adoption. I don't mind the 15-20m average charge time, but for people like my mom (boomer) who have zero patience, a gas-station speed charging situation would be huge.
I’m not a boomer and I don’t want to sit at a gas station for 20 minutes either.
There's 70 public chargers within a 10 minute drive of my house. I think that outnumbers gas stations, but they are hard to count on google maps. So people who are living in high density areas probably have a lot of charging options near by.
That's fixed easily - just get a Tesla Supercharger subscription, most should be open to other EVs.
Yes, that costs money (i think around 10€/month here) but you're saving after the first full charge compared to others (Ionity for example) - and that's 'round here in .de, not exactly the country with the lowest charging costs... (ftr, i think the current low-end on Superchargers here in .de either with a Tesla or a subscription is around 0.41€/kWh whereas with aforementioned Ionity charges at least 0,64€/kWh when roaming).
What we have right now is good enough for a lot of people. I don't live in the most EV friendly area, but I know a few people who own EVs with no at home charging. And one of my Tesla owning neighbors parks his car in the driveway regularly, only charging occasionally.
If gasoline shortages hit tomorrow, a whole lot of people claiming they couldn't own an EV because of the limitations would figure out how to make it work.
Whenever you see a CLTC range rating, just know its considered the most inflated of range ratings. Its basically 30% inflated from the already 20% inflated EPA range estimate.
It's incredibly easy to show excellent range when there is no wind resistance to worry about and you don't have to accelerate the car's actual mass around. It's basically a test of rolling resistance. Not quite a perfectly spherical horse oscillating in a pure harmonic motion, but much closer to that then an actual road test. A good rule of thumb is to cut the CLTC figure in half to estimate actual range, cutting it even more if the car is especially brick like.
An electric charging station with 8 charging booths (=~ gas pump) on a highway: 2.5MW.
A bit of work to prepare the grid...
It's probably not even too expensive.

Except 3/4 of the chargers there were out of order, and the remaining one was going at 30kW and there was a line.
After that drive, there was only one other station in range so I want there. There were 3 working 60kW chargers and an ICE’d in L2 charger and I was #2 in line.
When I finally got plugged in, it turns out that although the system purported to accept payment by credit card, you had to interact with the touch screen to do so, except the screen wasn’t actually a touch screen. So I downloaded the app, set the car charging, and went to lunch. And decided not to take the EV to the airport again until there are more DC chargers between there and home.
All of this was in Oregon.
I was on a mountain trip and there was a non-tesla charger. It was charging a leaf that had some kind of derate issue so the leaf was going to be there 4 HOURS!! The line of cars then waiting for that leaf to finish charging - those folks were SCREWED. Meanwhile, the tesla chargers were not that full mostly because the charges were pretty quick (250kw charger but I only pulled about 150kw because I hadn't preconditioned fully I think - it was deep winter with snow).
The non-tesla chargers are comical. They either don't work, or charge slowly or have weird payment / billing issues. All of this compounds the issues.
