Why charging infrastructure needs to be able to do more – and how the AC charging controller CHARX control modular makes the difference

Cybersecurity, regulatory requirements, future viability – sounds complicated? It doesn’t have to be.

At a time when e-mobility charging infrastructure must not only supply electricity, but also function safely, networked and in compliance with the law, solutions are needed that think ahead. The growing regulatory requirements are often underestimated – and this is precisely where Phoenix Contact comes in with its CHARX control modular AC charging controller.

The CHARX control modular AC charging controller is at the heart of smart charging infrastructure - safe, scalable and future-proof.

The challenge: complexity meets responsibility

Charging infrastructure has long been more than just a power connection. Operators today have to bill in compliance with calibration law, defend against cyber attacks, integrate new functions such as plug-and-charge or vehicle-to-grid and comply with legal requirements such as the RED Directive (from August 2025) and the Cyber Resilience Act (from 2027).

New and existing charging infrastructure on the market must now face various challenges:  Updates are complicated, certifications are lost, hardware has to be replaced. This costs time, money and nerves.

Thanks to open interfaces, CHARX control modular can be seamlessly integrated into smart grids, building management systems and backend systems.

The solution: a AC charging controller that thinks for itself

CHARX control modular is more than just an AC charging controller – it is the intelligent heart of modern charging infrastructure.
What makes the charging controller from Phoenix Contact special:

  • Modular and scalable: from individual charging points to charging parks.
  • Open platform: Supports all common protocols such as ISO 15118, OCPP, MQTT, Modbus/TCP.
  • Future-proof: New functions can be retrofitted via software update – without loss of certificate.
  • Secure right from the start: Including regular security updates and protection mechanisms according to current standards.
The modular design enables easy scaling from charging point to charging park - with minimal wiring effort.

Cybersecurity? Always included.

While many providers are still considering how to implement the new security requirements, CHARX control modular is already prepared today. Free software updates ensure compliance with the upcoming requirements of the RED directive and the CRA. In this way, Phoenix Contact accompanies its customers on the way to a safe and compliant AC charging infrastructure.

With regular software and security updates, your charging infrastructure will always be up to date - at no additional cost.

Regulatory requirements as a competitive advantage

There is a clear difference, particularly in the area of cybersecurity and compliance:
Phoenix Contact thinks regulatory requirements through right from the start. In doing so, the company relieves its customers of a major burden. Especially with regard to new legal requirements, which are often complex and dynamic, it is helpful to rely on a solution that already takes them into account. A strong advantage in a changing market.

Simple in practice - strong in the backgrounds

CHARX control modular is very easy to set up: plug-and-play modules, web-based management, remote access via VPN – everything is included. And if any questions do arise, Phoenix Contact’s multi-level support team can help quickly and competently.

Conclusion: All-round carefree - today and tomorrow

CHARX control modular provides manufacturers and operators with a solution that is not only technically impressive, but also secure and grows with them in the long term.
A real all-round carefree package that makes the charging infrastructure fit for the future and helps you focus on the essentials: your own core business.
