Can the common charging window cover the energy need?

What the model does

Battery energy = vehicles × distance × consumption ÷ 100. Grid energy = battery energy ÷ efficiency fraction. Effective power = min(site power, vehicles × vehicle charging limit). Window energy = effective power × hours. Required hours = grid energy ÷ effective power, when power is positive.

What to check before using the result

All vehicles are assumed to be present for the full window with one charging connection each. The model uses constant rates, no queuing and identical energy needs. It ignores arrival differences, charging curves, reserve policy, faults and driver behaviour. A positive aggregate margin does not prove a workable vehicle-by-vehicle schedule.
