Sorry, but I think you're wrong on your concern: in China they specifically fix this issue with buffer batteries. From grid perspective, charging is no different than with regular, slow charging stations. You can still limit their capacity (as in cars that can be charged per 24h), the difference here is you can charge quickly.
This is a good compromise for the time being while the grid catches up with demand.
- torginus 7mo agoBatteries only help with peak loads, they also cost money and wear out. Let's do some math - a 10 car 500kW charger, with a ~30% occupancy, would draw a constant 1500kW from the grid, if we calculate 3kW average for a household(which is high), that would be the equivalent of 500 households.
- cromka 7mo agoI don't think this speculation is needed here, what I described is literally how these super fast BYD/Xiaomi own chargers work in China.
- l1tany11 7mo agoSame thing in the US. Tesla does exactly that at their supercharger sites. Probably not all of them, but definitely some of them.
