Frequently asked questions about ev-pay
General
It is not necessary to scan the QR code or enter an email address. This can be a nuisance, especially during bad weather. This process cannot be carried out without a smartphone.
The ev-pay solution, on the other hand, accepts all common payment cards, whether digital or physical.
This makes the payment process using the ev-pay solution just as simple and efficient as, for example, the payment process at a conventional checkout at a petrol station.
ev-pay GmbH passes on charging station data (point of interest information) to aggregators such as “moovility”, which in turn appears in the car manufacturers’ navigation systems. ev-pay GmbH also works together with various map service providers.
This ensures that the customer has all the information about ev-pay available at the start of the journey and that the navigation system enables an optimal journey in terms of cost and time.
“CPO” stands for ‘Charge Point Operator’.
Charge point operators are responsible for the safe operation of the charging infrastructure. They are responsible for the operational management of the charging stations and their connection to an IT backend.
The term “CPMS” stands for “Charge Point Management System”.
A charge point management system facilitates the operation of charging stations by digitally mapping the entire charging network and enabling communication and data exchange between the individual charging stations.
These software solutions offer a clear display in which the status of all connected charging stations and charging processes can be called up. In addition, tasks and processes can be controlled and automated remotely.
The term “e-MSP” stands for “e-Mobility Service Provider”. It is often also referred to as EMSP, MSP or simply “provider”.
The e-Mobility Service Provider is the company with which the electric vehicle driver concludes a contract for all services related to electric charging. The e-MSP takes on various tasks, including the provision of charging passes, apps for searching and navigating to charging stations, managing and expanding the roaming network, billing and customer management and setting the prices for the driver’s charging sessions.
The term “PSP” stands for “payment service provider”.
A payment service provider is a company that provides payment services for other companies. For this purpose, the merchant’s systems are technically connected to the PSP, which enables payment processing via the desired payment methods.
Contract
The payment terminal is not provided by ev-pay GmbH. The hardware must be procured from FEIG ELECTRONIC GmbH, Hectronic GmbH or other integrators who use the payment terminal from FEIG that complies with calibration law.
Procurement, marketing and pricing are the sole responsibility of the CPO. ev-pay GmbH is not involved in the cash flow from the Emobilist to the CPO. This takes place from the emobilist directly to the CPO’s business account. This transaction is carried out using a payment service provider.
Services
By “dynamic” prices, we mean that the CPO can react to external price fluctuations in the procurement of electricity in real time and in compliance with calibration law and can pass on the final price to the emobility customer variably and according to its own logic.
As with refueling, prices can also be changed. At the start of the charging process, the prices (kWh price, blocking fee, parking fee and start fee) for this charging process are fixed. If prices are changed during the charging process, the changed prices only apply to the following charging process.
The prices can be set automatically via REST-API (Representational State Transfer – Application Programming Interface) or manually via the CPO access in the ev-pay HUB, in compliance with calibration law and for specific charging points.
It is also possible to combine charging stations into groups according to your own logic and assign group tariffs to them.
Technology
The charging station is connected to the ev-pay HUB via OCPP. Data that is not relevant for ‘ad hoc payment’ (such as roaming data) is forwarded unchanged to the CPO’s downstream CPMS (Chargepoint Management System) and processed there.
The ev-pay HUB communicates with the charging station via OCPP and transfers the data to the payment service providers and banks using the payment terminal, and vice versa.
Example: When the ev-pay HUB receives feedback from the PSP that the emobility customer’s account is covered and the pre-authorization amount has been successfully reserved, the ev-pay HUB sends the OCPP command Remote Start Transaction to the charging station and the charging process begins.
This procedure is carried out by the ev-pay solution in compliance with calibration law. ev-pay has applied for two patents for this procedure.

Yes, the ev-pay Hub logs into the CPO’s backend in the same way as a charging station would.
The ev-pay HUB provides the CDRs (Charge Detail Records) of a charging process. With the PSP’s consent, the transaction IDs can be linked to the CDRs. On this basis, ev-pay GmbH can send a report to the CPO’s accounting department so that it can automatically calculate the charging processes as easily as possible.
In any case, the CPO can have the receipts for its accounting department automatically transmitted via an API to the ev-pay HUB and then process them there.
A remote ev-pay payment solution for retrofitting all charging stations that comply with calibration law is possible via Hectronic’s Hecpay, for example.
For an ev-pay solution integrated into the charging station, only mechanical integration by the manufacturer is required. This currently requires a power connection and Internet access from the charging station. In the course of 2025, there will be a new variant that only requires a power connection and sets up the internet itself.
Yes, existing charging stations can be retrofitted if they use the OCMF data format and at least OCPP 1.6 JS for conformity with calibration law.
