easy charging
Paying for a charging session should be as easy as paying for a refueling session.
- Compliant with calibration law
- Charging station neutral
- Backend neutral
- PSP-independent
- Independent of payment terminal
- Internationalizable
- Integration of price signals from renewable energies
The challenge today
The various cards, apps and the high number of value creators increase the complexity of billing processes in emobility, which leads to high kWh prices. In addition, the travelcards are not barrier-free and generally require a continuing obligation to be entered into.


Our goal
A calibration law-compliant and charging station-independent solution for ad hoc payment with variable tariffs.
Certification of cloud-based software in conjunction with a tariff display device to be combined as an additional device with different, conformity-rated charging stations.
The additional device does not have to be mentioned in the certification of the charging stations. The charging stations are named in the certification of the additional device.
The ev-pay approach leads to CPO empowerment
- The Alternative Fuel Infrastructure Regulation (AFIR) stipulates payment by debit and credit card for all charging stations >50 kW from April 2024.
- The CPO has price sovereignty and direct contact with the ev-driver, as the ev-driver can purchase charging current directly from the CPO.
- This leads to a higher margin for the CPO and generally to lower sales prices for the kWh to the ev-driver.
- ev-pay enables this approach and thus contributes to a high level of acceptance among CPOs, but also among emobility enthusiasts and those who are not yet emobility enthusiasts.
*In the ev-pay model, the energy supply company share is higher in percentage terms, as the energy purchase from the energy supply company remains the same, but the sales price to emobility customers is lower than in the classic model in the upper range.
The ev-pay architecture

The heart of the system is the ev-pay tariff server (EPTS), which stores historical tariff information in a trustworthy manner.
Consumers can see at any time which tariff applied to their charging process and when. On request, the EPTS provides the currently valid tariff to the payment station. The payment station is only connected to the charging station via the cloud (retrofitting possible from 01.01.2027 in accordance with the AFIR)! The CPMS (Charge Point Management System) of the CPO can continue to be used. The charging cards will continue to be billed in it. The EPTS monitors the entire process and the accuracy of the ad hoc billing process and ensures a reliable link between the measured values and the tariff. The receipt can be called up afterwards.
Your benefits with ev-pay
Ad hoc charging authorized with Girocard, debit and credit card via a local payment terminal with the following advantages:
Charging station neutral
Backend neutral
PSP-independent
Compliant with calibration law
Internationalizable
Price signals
ev-pay focuses exclusively on the processes of ad hoc charging and receives a percentage of the transactions carried out.
Where is ev-pay used?
The ev-pay offer is needed in essential charging scenarios and will greatly simplify public* charging!
The ideal solution…
- ... at Charging Hubs (City Hubs and Trans European Axis)
- ... while shopping
- ... to depots
- ... at work
- ... in multi-family houses
A certified payment terminal is required separately to use our electronic cash register system. You can request this directly from our hardware partners.
*Public charging is anywhere where the Emobilist is unknown to the CPO and can charge on the CPO’s property.
Certified & future-proof
FEIG and ev-pay are officially compliant with calibration law
The Physikalisch-Technische Bundesanstalt (PTB) has certified our “payment software” in combination with the cVEND PIN.EV payment terminal from FEIG in accordance with German calibration law – in accordance with both Module B and Module D.
This means that the manufacturer-independent payment solution can be used at public charging stations in Germany in compliance with calibration law.
With consumer protection in focus, we now offer a user-friendly combination that enables CPOs to operate charging stations in compliance with AFIR.
