I challenge this on the cost front and on the power front.

There is zero reason why a fast charger should be $100,000 other than the fact that the volume is sufficiently low that these are all hand built. The semiconductors in that thing can't possibly be $100,000 in volume. Copper is roughly $10 per kilogram--or $100,000 and you could use 10 metric tonnes--there is no way those things hold 10,000 kg of copper.

As for the power, these things are probably more than 90% efficient, so they don't use any more power than the smaller ones (the load they are charging is a fixed size regardless of how fast you charge it). They may use more current, but that's the whole point! These things charge your car faster.

The biggest issue with installing these at home is probably access to genuine 440V (or higher) 3 phase. And you probably get around that by making the charger the equivalent of a Powerwall--it stores the energy at normal 220 feed levels but blasts it into your car from it's own batteries as fast as it can.
