game changing though?
For me, if the charging time can be cut in 3, so that a motorway piss stop takes the battery from 20 % to 80% in sub fifteen minutes, for a 300mile+ range, that is game changing.
And seems possible, nay likely, in 24 months from now.

Nah, battery tech is the one thing that hasn't really significantly improved. They can use cooling to handle discharge and charge better, they can coil to improve capacity... but fundamentally the best battery tech remains the same chemical process it always has which is bound by the laws of physics.
The big thing to happen to batteries in the last 20 years is really their price coming waaaay down.
There's a lot of research in batteries and has been for a few decades now, and the best we've had are tweaks.
Weirdly the best idea remains the one Tesla started with... async trickle charging by swapping out the batteries at designated stations and charging more slowly whilst they're not in use. But people don't like that, and it's prone to it's own problems and complexities, and so here we are fast charging and attempting to cool in the process, reducing the overall life of the batteries in the hope of overcoming people's range anxiety from charge times.
I drive electric everywhere I can in London, but there's so many issues still with lack of infrastructure across London (let alone UK), limited charging spots at motorways (occupied for long times due to slow charge times)... and damn, I didn't want an internal combustion but I am very very happy that I've got the dual-drivetrain thing with a petrol engine up front as at least I can overcome the lack of infrastructure easily and without inconvenience.
Sucks though... this is one thing I wish would change. We should get to the point that every lamp post is a charging point, but it feels so far away.

(0.6*300 miles * 0.25 kWh/mile) / 15 minutes = 180 kW
There are already cars and chargers that claim to do that, but usually only for beginning of the charging cycle (e.g. 0-60%).

i hear that dude. I am not anti in any way. EV is the future.
game changing though? i have a feeling no new car is going to knock my socks off for a while yet. which doesn't matter anyway as will never own a new anything except undercrackers and shoes
