Control Modules for EVSE

Hardware and software solutions for the current charging communication
according to DIN70121 and ISO 15118

EC-CHARGE: Steuerungsmodule für EV und EVSE

Electrical Charging

With EC-CHARGE© we offer hardware and software solutions for the current charging communication and support all previous standards at the same time. The solutions offer charging communication according to DIN70121 and ISO 15118 and holistically cover the charging station side EVSE, thus enabling maximum interoperability of the power line communication PLC.


for Charging Stations

Solutions for your charging station: retrofit or new development


Charging stations which are not yet using the current mode-3 charging procedure in accordance with ISO 15118 can be updated cost-effectively: The modular retrofit set EC-CHARGE-EVSE© makes it possible to either simply upgrade charging stations with EC-CHARGE-EVSE© or to support new charging stations based on EC-CHARGE-EVSE© (DIN 70121 compatible as well).


EC-CHARGE-EVSE© – a modular, manufacturer independent retrofit for charging points – This product offers a modular build in both hardware and software conversion, is ready for mounting on the DIN rail and is suited to basically upgrade charging stations from all manufacturers. As an integrated solution EC-CHARGE-EVSE© replaces outdated control systems for AC charging stations while the rest of the installation remains fairly untouched. Due to the modular build, a needs-oriented configuration is possible and hence only necessary components are deployed. There are for instance single and dual core options for the micro-controller, an optional LTE connection (OCPP to backend) or WiFi/BT connection. A second implementation variant was developed with a focus on DC charging stations, with a DIN 70121 and ISO 15118 compatible communication. → product sheet

EC-CHARGE-EVSE© Initial Equipment

EC-CHARGE-EVSE© – a modular, manufacturer independent initial equipment for charging points – As an integrated solution, EC-CHARGE-EVSE© can be used as a control system for both AC and DC charging stations. Due to the modular build, the configuration for new developments happens needs-oriented. Again, the optional LTE connection or the Wi-Fi/BT makes a connection to the backend possible. → product sheet

Individual Charge Control based on EC-CHARGE-EVSE©

You have specific requirements on installation space or hardware and software conversion?

We offer an entire range of consulting and engineering support as well as component manufacturing later on in the process. Based on EC-CHARGE-EVSE©, we can develop individual solutions according to your specifications.

Advantages of EC-CHARGE-EVSE©

Modular Build

The retrofit set is ready for mounting on the DIN rail and can be deployed needs-oriented in different gradings.

Compact Design

Goal-focussed development and the use of modern hardware components result in a compact hardware design which can be easily adjusted to a customer specific installation space.

Commercial Vehicles

The infrastructure for both cars and commercial vehicles is supported, which differentiates EC-CHARGE© from other systems.


Software and electronics are of a modular build – equipped with a hardware and software architecture that enables to flexibly support different manufacturers. Moreover, due to this concept, functions which are not needed today can be easily retrofitted or activated later on.


According to customer requests, individual adjustments and integrated solutions based on the customer’s charging infrastructure are possible.


The encrypted charging communication (only ISO 15118) is in compliance with the latest security standards and also applies to the OCPP. The individual modules are sealed and hence unaffected by temperature changes, moisture or condensation.

Extensive Support

For the retrofit of different types of charging stations, our experts from the fields of electronic and software development will assist you. We offer to create a fitting design including the implementation of the user interface and the documentation for the end customers.
