FEIG and ev-pay Achieve PTB Approval for EV Ad-Hoc Payment Solution
The German Physikalisch-Technische Bundesanstalt (PTB) has officially certified a joint EV charging solution by ev-pay and FEIG ELECTRONIC in accordance with Germany’s calibration law. The certification includes both Module B and Module D, confirming that ev-pay’s POS software and FEIG’s cVEND PIN.EV payment terminal meet the strict legal requirements for public EV charging in Germany.
Independent, Transparent, and Legally Compliant
The certified system enables manufacturer-independent, backend-neutral, and calibration-compliant ad-hoc payments. Designed to streamline public EV charging infrastructure, the solution removes the need for third-party aggregators or roaming platforms, returning full pricing control to Charge Point Operators (CPOs).
With this, CPOs benefit from higher margins, and EV drivers benefit from lower, more transparent pricing per kilowatt-hour — a direct result of eliminating intermediaries in the payment chain.
Hardware Meets Software: cVEND PIN.EV and ev-pay POS
At the center of this innovation is the cVEND PIN.EV, a robust terminal developed by FEIG that connects EV charging infrastructure to financial networks. This hardware is paired with ev-pay’s POS software, which handles tariff display, transaction processing, and all compliance documentation required under German law.
Thanks to its modular design, the system can be integrated into existing charging stations, regardless of brand or manufacturer. This makes it a cost-effective retrofit solution, especially for older stations lacking card readers or display systems.
Dynamic Pricing and AFIR Compliance
A key innovation is the support for dynamic pricing — a rare feature in today’s ad-hoc charging market. While most spontaneous users are subject to fixed prices, ev-pay’s software allows pricing to adjust in real time based on demand, time of day, or real-time electricity market prices.
This enables operators to manage peak loads, align prices with renewable energy availability, and comply with the upcoming Alternative Fuels Infrastructure Regulation (AFIR). As a result, the solution not only benefits users and operators but also supports grid stability and the energy transition.
Strategic Investment and Market Validation
In October 2024, Enercity AG, a major German utility, became a strategic investor in ev-pay, acquiring a 25.1% stake. Other shareholders include FEIG ELECTRONIC GmbH (25.1%), Hectronic GmbH (3.9%), and the founding team (45.9%).
“This certification is a turning point for public EV charging in Germany and Europe,” says Dominik Freund, COO of ev-pay. “We’re giving CPOs full pricing control while enabling legally compliant and flexible billing.” Co-founder Felix Blum adds, “Despite technical challenges, we’ve developed a highly robust and user-friendly product that’s ready for widespread deployment.”
