What does a charger's profit and loss statement look like?

Revenue by route (ad hoc, roaming, time fees), energy as the one cost per kilowatt-hour, payment and roaming fees, then the fixed lines: depreciation, site, service, software, overhead. The deep dive reads one charger's year line by line.

Business models · Deep diveOne charger's year, as the controller books itThe annual statement of the DIY store charger, line by line: energy delivered, ad hoc and roaming revenue, the energy bill, fees, depreciation, site, service, software, overhead, and the result at 10% utilisation.
  • Two kinds of lines. Revenue, energy and fees are per kilowatt-hour: they rise and fall together. Everything from depreciation down is per year: it falls due regardless. The result is the gap between the two groups.
  • Timing. Ad hoc money arrives within days from the card acquirer; roaming money arrives weeks later from the providers (stop 02). The statement ignores timing, the cash flow does not.
  • What is not here. VAT, which passes through; the providers' margins, which are their statements; and the store's extra sales, which are the host's reason to say yes (stop 04).

  1. RoamingCharging in another company's network with your own card or app.
  2. Ad hocCharging without a contract, paid directly at the charger, for example by card or QR code.
  1. Why is public charging more expensive than home charging?A public charger adds hardware, a grid connection, the site, operation and payment. The IEA reports public fast charging prices up to 240% above residential tariffs.
  2. How do charging companies make money?Operators earn from energy sold ad hoc and through roaming, plus time fees and flexibility; providers from the difference between their prices and operators' tariffs, or subscriptions.
  3. Is a charger profitable?It depends on utilisation: fixed costs are the same whether ten or a hundred cars come, so every extra session lowers the cost of every kWh.
