1500 kWh battery storage + 600kW grid draw + 30kW solar canopy (if weather allows).
@10m per car across 2 cables = ~36 cars over 3 hour rush hour throughput (comparable to 2 gas pump) = need ~4000 kWh, 1500 kWh from battery 1800 kWh from grid = 3300 kWh. This worst case all cars 0-97% charge, realistically mixture so 3300 kWh should cover typical peak scenarios. Then midday lull for grid to refill batteries for evening rush, after again overnight charge from grid. Basically 1x2cable station can service 100-150 cars/day comparable to high-density gas pump.
In terms of physical size, battery storage smaller than gas in terms of physical infra = doesn't need to be underground (assuming long term blade safety ensured). Gas needs storage for multiple days / week so need to scale underground tank accordingly. 1500kWh scaled for rush hour = battery storage (recycled) realistically ~30 recycled blade1s slapped into racks, a couple parking spaces worth, and can be stacked vertically. It's much more space efficient (and cost efficient) than gas.
