So how exactly do they intend to supply 1500-2100kW in a residential application? For 220V service that’s 9000A per phase? In order to charge these batteries will require direct taps to high voltage service because residential 220V simply will not feed these batteries. That’s going to force a “fuel station” refilling model. And that’s a huge infrastructure power drain. A Tesla supercharger by comparison I believe is around 250kW.
If people just want an EV this helps close the gap on refueling stop times… once there is actually enough of these stations to meet need and the grid infrastructure to feed them
