Our CHARX control AC charging controllers control and monitor the standard-compliant mode 3 charging of electric vehicles. The controllers can be configured via a browser or DIP switches and have interfaces for communication with energy meters and energy management systems. Optional functions include a 3G modem, RFID user authorization, DC residual current monitoring, automatic charging connector release in the event of power failure, and integrated load management in master-slave operation.

Your advantages

  • Standard-compliant AC charging in accordance with IEC 61851-1, SAE J1772, and GB/T 20234
  • High flexibility with extensive configuration options
  • Easy implementation of intelligent charging infrastructures with integrated load management
  • Easy integration into management systems with standardized communication interfaces

From a single charging point to networked charging infrastructure

Our CHARX control charging controllers can be operated both autonomously and in networks. Status data is acquired via the integrated communication interfaces, and controlled intervention in the charging process is supported. Here, we focus on the use of standardized communication interfaces and protocols, therefore providing easy connection options to a variety of automation systems.

CHARX control basic for private applications

CHARX control advanced plus charging controller in a DIN rail housing with optional 3G modem

This charging controller combines all relevant control, communication, and monitoring functions in one compact housing. Along with Ethernet and RS-485 interfaces, the controller features DC residual current monitoring, an automatic connector release mechanism in the event of voltage failure, convenient user authorization via RFID, and convenient configuration via web interface.

Optional features include OCPP-capable cellular communication, Ethernet interfaces, and integrated load management. Here, the master controller distributes the available connection power to up to 10 slave controllers as protection against overload.

Application example: Charging point with backend integration

Charging point with energy meter and cloud-based billing via cellular communication  

Charging point with CHARX control advanced plus, energy meter, and cloud-based billing via cellular communication

With the optional CHARX control advanced plus OCPP interface, you can link a charging station to cloud-based billing systems via Ethernet or cellular communication.

An MID energy meter can be integrated into the application for precise billing. This makes the controller an ideal solution for public applications.
