I pretty much agree. To prove this theory wrong they have to produce a working prototype with those capabilities.
Those capabilities don’t even make sense.
— Do ICE cars have 750 mile range? No. If you could really charge a battery that quickly, there’s no real reason to have more range than a typical ICE car, and you could follow ICE car habits. The incentive would be to make the car cheaper at that point.
— will that change charging at home? Also, no. I have a 50a charging circuit, similar to my 50a stove circuit. Many houses have wiring that can support that, or it’s not too big a change to support that. That’s sufficient for a full charge on pretty much any EV (except maybe that horrible excuse for excessive consumption that is the Hummer), but I’m usually just topping off from whatever I used during the day. If anything, EVs should get more efficient, so my overnight charge will support more range. A homeowner will never be able to afford the infrastructure to support that ten minute charge time. Even, say doubling the charge: a 100a charging circuit likely means upgrading your electrical service for most people, so now it’s expensive, and most of the time that’s wasted.
— will that change supercharging? Also, no. Think of how expensive superchargers already are: you already meet or exceed the cost of fuel for ICE cars. Now imagine the cost of the infrastructure to double or triple that charging rate. Are you really going to pay that premium?
Personally I’m really liking changing my habits to treat fueling my car like my phone: plug it in at night and it’s just always ready.
When they talk about these fast charge times, it's always about DC fast chargers. Home chargers (levels 1&2) simply don't need it, have never been close, and no one really cares. This is fodder for the road trip mentality, or counter-FUD to the FUD that charging is long and slow.
If it actually pans out, I'm sure we'll start to see DC fast charges advertising their speed, possibly with a premium price. It's already a detail being tracked, it just doesn't usually take a front seat.
