Charging sites earn through five mechanisms: fees drivers pay for the session; a host business paying for charging as an amenity; contracts to charge a fleet or a workforce; the dwell value charging brings the host’s main business; and participation in funding programmes and networks, on programme and platform terms. Most sites combine two or three. None has a standard amount — what a mechanism earns is read from the site’s own session and cost records.
Key Takeaways
- Sites earn five ways: driver fees, host-paid amenity, fleet and workplace contracts, dwell value, and programme or network participation.
- Each mechanism has a payer, a precondition and a running cost — design the mix before choosing hardware.
- Per-kWh billing and metering rules are jurisdiction confirmations, closed before a tariff is published.
The Five Mechanisms at a Glance
| Mechanism | Who pays | What must be true | What it costs to run |
|---|---|---|---|
| Driver fees | The driver, on a per-kWh, per-session or per-hour tariff | A platform the hardware pairs with; local selling and metering rules confirmed first | Platform and payment costs per their terms, driver support |
| Host-paid amenity | The host business; drivers charge free or at a staff rate | A host who values the amenity — staff, customers, tenants — above fee income | Electricity and upkeep sit with the host; access still needs managing |
| Fleet and workplace contracts | The fleet or employer, under a written contract | Vehicles returning on a duty pattern the contract can be priced against | Contract administration and the service duties it writes down |
| Dwell value | Nobody pays at the charger; the benefit lands in the host’s main business | A business drivers wait at — retail, food, leisure | The costs still exist; the return is counted, if at all, in the host’s own sales records |
| Programmes and networks | Funding programmes, or roaming settlements under a network’s terms | The site meets the programme’s stated conditions — under U.S. NEVI rules: DC ports of at least 150 kW, open 24/7, contactless, uptime above 97% | Compliance, reporting and uptime duties, as the programme documents write them |
Driver Fees: The Only Mechanism With a Tariff
Driver fees are the mechanism people picture first — and the one with the most homework. Tariffs are compared in our guide to how charging stations set prices. What this article adds is the boundary: whether you may bill per kWh at all, and what metering accuracy that requires, is set by the rules of the market the site sits in — a confirmation to close with the utility or regulator before a tariff is published, never a planning assumption. Billing itself is platform work: the charger must state the protocol the platform needs; the platform, not the charger, holds driver accounts and takes payment.
The Hardware Layer Under All Five
Every mechanism runs on the same installed base, so hardware is chosen against the mechanisms it must serve. For fee and network models, the EV-AC03201T dual-connector AC station states OCPP 1.6J — the protocol claim a platform pairing is checked against — with two Type 2 connectors sharing up to 43 kW, RFID access and an IP54 floor-standing form. Its touchscreen is a display, not a payment terminal: card acceptance is the platform’s layer. For host-paid amenity models, a wallbox such as the EV-ACT3204PE (22 kW three-phase, Type 2, RFID and app) gives access control without a public tariff. The EV-RHDC30K-L adds compact DC at 22 kW for destination and depot dwell — below the DOT DC fast band and NEVI’s 150 kW port level, so it is not corridor hardware. Site builds start from the commercial charging range; bring the mechanism mix to the project conversation.
Frequently Asked Questions
Can one site use several mechanisms at once?
Yes, and most do — a fleet contract on weekdays, driver fees in the evening, a host subsidy underneath. The discipline is in the contracts: the same port cannot be promised to a fleet’s duty pattern and sold to the public in the same hours.
Can I simply charge drivers per kWh?
Only where your market’s rules allow it, with metering that meets its requirements — confirmed with the utility or regulator for the site before you set the tariff. Where per-kWh billing is not the route, session or time structures are the platform alternatives.
How much does a charging site earn?
There is no sourced figure to quote. A site’s earning is its mechanism mix multiplied by its measured utilisation and tariffs, minus its own recorded costs — the arithmetic our analysis of whether a charging station business is profitable works through. Anyone selling you a number before your site has records is selling the number, not the site.
