you are being pedantic about 350kw chargers being 766V is it ?
agree there's little in it and only at the low soc that the additional power is useful 0-80% 30 minutes in the Y and 20 minutes in the EV6
not sure what charge rate supercapacitors may offer, but, getting turnaround at the public chargers is desirable(like ice), although,
if you have multiple bays you can efficiently get throughput for multiple vehicles at different states of charge, and optimise use of charge station supply.
I don't know ? does the 800V charging battery configuration give any benefits for drivetrain efficiency/reliability ie. invertor/motor.
Not really no, the Ionic V/EV6 are both slower and get significantly worse efficiency despite being a very similar size to a model Y.
Realistically I don’t see chargers getting much faster than what’s on offer today. certainly no more than incremental increases.
There are huge issues with getting sufficient power to the locations of chargers. Not only that their off-on-off-on-off nature means it’s also very burdensome for the grid to tolerate (read expensive).
You either need batteries to balance out the power draw or you need to pay for the grid to do that for you. Either way, it’s very expensive.
What we need right now is more plugs capable of around 200kw, not fewer 350kw or above plugs.
Right now, if I had the choice of a service station with 12 150kw plugs or 6 350kw plugs, I’d take the 12 any day of the week. They would be far more useful to far more people at the moment.
