What decides whether a charging site pays off?

Utilisation: sessions and energy per day measured against the fixed costs. Location, roaming reach and availability all feed into it.

EV charging fundamentals · Stop 07Who owns the charger?The contracts behind one charging site: who invests, operates, supplies hardware and software, connects the grid, and why utilisation matters most.

The fixed costs of a site run whether cars come or not. Below a certain utilisation a fast-charging site loses money, above it every additional session improves the result. Location, roaming reach and availability all feed into this figure, which is why every earlier stop of this path ends up here.

  1. RoamingCharging in another company's network with your own card or app.
  2. UtilisationHow intensively a charger is used, for example in sessions or energy per day.
  1. Who pays for the chargers at a supermarket or service station?Either a CPO finances, builds and operates them and the site host receives rent or a revenue share, or the host runs them itself.
  2. Why do hotels install slower chargers?Guests park overnight, so 11 kW AC fits them. The power of a site follows how long people stay.
  3. Why does charging involve so many companies?Three things spread the work: the grid connection, the location where people park, and contracts that work across many networks. One company can hold several roles, but the roles stay separate.
  4. Who is the CPO and who is the eMSP?The CPO operates the charger and keeps it available. The eMSP issues the card or app, sets the driver's price and sends the invoice. One company can hold both roles.
