The thing is: with 5min charging, it reduces the amount of situations where there's a queue at all.

Again, 9 batteries is just an hour worth of energy if car are lining up. The goal of such battery is just to smooth the demand spikes, not to get though peak hour.

I suspect this will depend a lot on the expected usage of the charging station (an maybe adapted later on if the usage doesn't match their expectations), as I said above it's going to be a full time job.
