Integration of a new charging station into the Eponet backend
Eponet has already integrated more than 30 charging station manufacturers into its backend. Some are only integrated for administration/billing via the OCPP protocol, but most are also integrated into the Eponet load management system.
OCPP integrations can be implemented relatively quickly thanks to the OCPP protocol (provided the manufacturer complies with the protocol) – however, integration into load management is often an underestimated undertaking.
Please do not confuse the two integrations. Most backend providers only do OCPP integration, and load management is provided by a third-party company.
The following picture story explains why the effort involved in integrating load management is so time-consuming and why, despite transport and installation in our laboratory, it is still cheaper than on-site integration.
Picture story from the Eponet test laboratory – DC charger integration process
Experience has shown that a serious integration into Eponet load management takes 2-3 working days for several people. Eponet has set up a special test laboratory for this purpose, where several vehicles can be connected at the same time.
Why we are reluctant to carry out on-site integration: If questions or problems arise, the manufacturer usually has to be consulted, or the distribution partner has to make internal enquiries, and we often only receive the answers after several days. If we carry out on-site integration at the customer's premises, we would have to return to the site several times for testing. We therefore recommend integrating the charger in our laboratory.
Start of integration: Scheduling / organisation Delivery & setup
Delivery of DC chargers and power packs to the Eponet test laboratory:
Unpacking, installation of power packs, connection and configuration
Configuration, initialisation of power packs with the manufacturer
Function checks, test charges
Integration into the Eponet portal and load management. Testing of controls. Test operation with several vehicles
Conclusion / closing remarks
The effort involved in integration varies depending on the product and manufacturer. From delivery to installation, connection and commissioning to the procurement of documents and protocols.
The surprise factor should not be underestimated: rarely, if ever, does everything go according to plan – from missing or incorrect documents to software bugs and defective power packs, we have seen it all. Sufficient time reserves should always be planned for.
