Integration of EV charging infrastructure, monitoring,
and on-site power production
The sale of electric cars poses new challenges for car dealers. In order to supply the vehicles with electricity, they have to integrate a charging infrastructure into the car dealerships. With coneva Charging, coneva Monitoring and Dynamic Load Management, coneva offers solutions that limit investment and electricity costs at the same time.
The Project
German car dealer Motor Center Heinen would like to build a charging infrastructure for EVs at five locations that meets the current specifications of the various car manufacturers. In addition to cost-efficient operation, they want to integrate the charging infrastructure into the existing energy structures and building loads. In addition, the operators want to create a database on the basis of which they can react to changing requirements in the energy system at any time.
The Challenge
The challenge here is the unrestricted operation for EV charging despite limited building load. This is because, for historical reasons, the energy supply in the car dealerships has already undergone several expansions and adaptations. Even currently, the available building connection capacities are not sufficient for unrestricted operation of the required charging infrastructure. Therefore, a solution is needed that takes into account the actual power requirements and conditions on site. In addition, this should then be used to determine the exact charging infrastructure and at the same time keep investment and operating costs low.
The Solution
coneva Charging offers a solution for setting up the EV charging infrastructure geared towards optimizing operating and investment costs. To this end, the current energy supply (e.g. current building load, load peaks, on-site power production) was first analyzed at all five locations. And then a concept was developed, taking into account the charging infrastructure desired by the customer.
According to these requirements, 2 resp. 3 AC charging points (22 KW each) and a DC fast charger (25 KW) were installed on site. A further AC charging point (22 KW) is available for service within the workshop. All charging points have been integrated into a site-specific, dynamic load management system. In order to cover additional energy requirements and to become more independent through on-site power production, new PV systems were installed on the roofs of the locations. With the central coneva monitoring system, the operation of the charging infrastructure, but also the complete energy supply of the sites, can be centrally monitored, evaluated and adjusted
The Result
coneva integrierte eine Ladeinfrastruktur in die fünf Standorte und schaltete dabei auch alle Ladepunkte auf das standortübergreifende, zentrale Monitoring auf. Daten aus der Gebäudetechnik und der Eigenstromproduktion sind dabei ebenfalls integriert. Dies liefert die Grundlage für den weiteren optimierten Betrieb. Durch das integrierte Dynamische Lastmanagement zeigen sich erste positive Ergebnisse:
- Denn es sorgt dafür, dass die tatsächlich in Anspruch genommene Leistung des Hausanschlusses ständig gemessen, bewertet und jeweils die freie Ladeleistung an die Ladeinfrastruktur verteilt wird.
- Dabei erfolgt die Zuordnung und Verteilung der Leistungsgrenzen stets unter Berücksichtigung der maximalen Hausanschlussleistung, der Nutzung der Ladepunkte, sowie einer vorgegebenen Prioritätenschaltung.
- Dies führt von Beginn an zu einer Reduktion von Investitions- und laufenden Stromkosten.
