Charge Controller for EVSE

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. All charging plug types are supported – CCS1, CCS2, and NACS.

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. The charge controller is implemented for mounting on the DIN rail and is suited to upgrade charging stations basically 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 As an integrated solution EC-CHARGE-EVSE© replaces outdated control systems for AC charging stations while the rest of the installation remains fairly untouched.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. The dual-core hardware variant is usually sufficient, but a quad-core variant is also available. An optional LTE connection via OCPP to the backend or WiFi/BT is also offered. A second implementation variant was developed with a focus on DC charging stations, with a DIN 70121 and ISO 15118 compatible communication. → product sheet

REGULATION (EU) 2024/1804 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL is currently being ratified and is due to be adopted in October 2024.
The EC-CHARGE-EVSE charge controller already fully implements this regulation.
EC-CHARGE-EVSE is the ideal solution for replacing your existing charge controllers and is also already prepared for bidirectional charging in accordance with ISO 15118-20.
Details on the regulation: Based on this regulation, charging stations after March 2025 will only be permitted with a communication device in accordance with ISO 15118. This applies to all charging stations, both those that are converted and those that are newly built. The regulation applies to wallboxes, ICCPDs (In Cable Control Power Device), AC charging stations (alternating voltage) and DC charging stations (direct voltage).

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. Different variants of the OCPP protocol are supported. → product sheet

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.

You need consulting and engineering services for EV Charging? We offer assistance from concept development over software development up to bench tests.

With the Embedded Academy’s e-learning “Communication in EV charging”, you will gain a basic understanding of charging communication within a very short time. We inform you about system approaches to electric charging, charging norms and standards, charging modes according to IEC 61851-1, low-level communication with pilot signal and duty cycle, and high-level communication via power line communication PLC.

What is the difference between a PLC modem and a charge controller?

A PLC modem only implements the communication between the charging station EVSE and the electric vehicle EV. The EC-CHARGE-EVSE charge controller, on the other hand, is the central electronics and software, the intelligence within the charging station. One of the functions of EC-CHARGE-EVSE is the PLC modem functionality. In addition, all components in the charging station are also controlled via EC-CHARGE-EVS0E. Also, EC-CHARGE-EVSE implements the connection to the backend.

Does EC-CHARGE-EVSE support the two charging standards DIN70121 and ISO 15118 simultaneously with one charge controller?

Yes, the charge controller EC-CHARGE-EVSE supports both data exchange charging standards in one software package. During communication, it is determined whether the electric vehicle EV wants to communicate with the charging station via DIN70121 or ISO 15118. The software then selects the appropriate charging standard.

Can EC-CHARGE-EVSE also be used for NACS?

Yes, EC-CHARGE-EVSE fully supports the North American Charging Standard NACS.

Can I connect different displays?

Yes, EC-CHARGE-EVSE supports a wide range of resolutions and displays. It is also possible to adapt to other connectors and protocols.
