Utilisation scenario
Utilisation = percentage of theoretical maximum energy throughput. New public chargers typically start at 20–35%; well-established sites may reach 60–80%. High utilisation is not guaranteed.
Revenue inputs
AC: 7–22 kW. DC fast: 50–150 kW. Actual throughput depends on vehicle acceptance rate.

Per-session estimates
Session estimate assumes ~45 min at rated power. Actual session energy varies by vehicle and battery state.
