Faster charge rates lessens the burden on charging infrastructure. Getting this right kills two birds with one stone.
It’s exactly the opposite and the utilities are allowed to charge extra for it. Look up “demand charge”.

Now somebody quickly
It was so satisfying hearing the charger crack ice.
I’ve been wondering how that mechanism works in freezing temps.. door handles do well too?

I thought he was referring to the faster the charge time (at a public charger), the less time someone is taking up a charger, and potentially reducing waiting in line times to charge.

Somewhat off topic but I wonder how future solid state batteries with 135kwh packs charging at up to 4C are going to impact electrical infrastructure.
So we spend 10+ years and trillions of dollars building a nation wide 350kw DC charger network and in 2023 I buy a hypothetical solid state EV that charges at 1200kw... now what!

I understand your point but the network has not to date been that expensive to build out. EA has spent a couple of billion, Rivian probably budgets a billion for its 600 sites (estimate someone gave was $150k per fast charger stall, six stalls equals a million dollars). Tesla has spent some and with that money people can go across country reasonably well. Obviously more locations are needed and stalls, getting rid of CHAdeMO and 50KW chargers which are old will help. At least we have a good degree of standardisation and 350Kw being the new standard.

181kw @ 52% for folks.



Edit: I'd guess the charger would have said 200kw+ for this.

The truck is also estimating about 290 miles in conserve. Which seems typical for folks not in Michigan.

Perhaps he was but to me infrastructure means infrastructure.
On paper at least, fast chargers with battery buffers seem like a good idea: https://www.greencarreports.com/new...ger-a-model-for-filling-in-fast-charging-gaps

In theory, it should allow fast charging without stressing the infrastructure. Also, should/could allow installing fast chargers in places where the grid is currently not wired to support it.

It is a good stop gap measure to bring dcfc to more places, but not viable once ev demand increases significantly.

I like the concept of the molten battery paired with dcfc, if they could get the tech to a commercial level. Still just a stop gap though.

Clearly the answer for large interstate corridors (or other busy highway) are a lot of rest areas and travel plazas powered by these: https://inl.gov/trending-topic/microreactors/
And if the government won't help with rest areas, Rivian could use these as part of a mobile charing and recovery fleet. Just have to hook up some R1Ts to tow these chargers to all those stranded EVs who ran out of range towing their toys up and down the Ike Gauntlet.

Just drop the middle-man and build a mini modular reactor that fits in the frunk. U-235 is cleaner than the coal and oil used to power a lot of the grid right now ?
I'm still annoyed that we haven't developed Mr. Fusion yet. BTTF2 promised that we would have those, and flying cars, by 2015!

Honestly I love this solution for the grid in general. Pepper a bunch of these 1-10mw micro reactors through neighborhoods and decentralize the grid. I didn't know INL was developing them. I recently read an economic feasible study for powering remote Alaska towns and mines using micro reactors instead of shipping in disel. It was a very good fit.

Only place you'd need larger plants then would be dense urban environments.
