> what grid can support this?
The charging rate is limited both by the charging controller on the car, and the controller on the charging station. The standards for both of these are developed in consortia that include representatives of utilities and grid operators, so these things get taken into consideration at a very early stage.

Yes, as you say, specialized stations that have a buffer between themselves and the grid.
Also, regenerative braking requires storage systems to absorb much higher instant power than plug in charging. If the round trip efficiency of these is better than existing battery tech, that would also improve overall range.
- giantg2 6y agoI could see the braking being an improvement. But I just don't see it justifying the decrease in range.
- danans 6y agoAgreed, but I think the decrease in range could make sense for frequent start and stop use cases like city buses, which also are less hampered lower energy densities because of their high volumes.
- giantg2 6y agoI think that could make sense. They could also bring back the electric trolleys that the buses killed off in the first place. Not sure which one would be lower for infrastructure and maintenance costs.
