A public hub is a system of bays, vehicles, power and service operations—not just a sum of charger nameplates.
Model throughput against real constraints.
Session energy, arrival patterns, vehicle acceptance and bay occupancy determine useful throughput. Divide daily delivered energy by the site’s theoretical full-power energy only when you label the denominator and period explicitly.
Separate shared power from connector count.
A cabinet may distribute power across several dispensers or connectors. Ask for the simultaneous-output envelope at the planned operating voltage and for the behaviour when a module is unavailable.
Assess economics before expansion.
Our Charging Economics tool exposes revenue, variable cost, fixed annual cost and capital recovery under a flat-energy scenario. It deliberately excludes demand charges and tax. A decision needs the actual tariff, costs and credible demand study.
Build a service plan into the project.
Measure successful sessions, energy delivered, payment completion and restoration time separately. Track connector availability and site availability with stated definitions. An impressive uptime percentage can mask a poor customer experience.
