Motor Center Heinen

Economic integration of charging infrastructure, monitoring and on-site power production

Multi-brand car dealer with five sites in the Ruhr area, Germany

The project

At all five locations of Motor Center Heinen, an e-charging infrastructure is to be set up that meets the current standards of the various car manufacturers. The solution must be operated cost-effectively and integrated into the existing energy structures and building loads. In addition, a database is to be created that can be used to react to changing requirements in the energy system at any time.

The challenge

Unrestricted operation of e-charging with restricted building load limit For historical reasons, the energy supply in car dealerships has already undergone several extensions and adjustments. The available house connection services are no longer sufficient for unrestricted operation of the required charging infrastructure. A solution is needed that takes into account the actual power requirements and conditions on site and, based on this, determines the precisely fitting charging infrastructure and keeps investment and operating costs low.

The solution

Central control and dynamic load management for optimized operation 

coneva Charging offers a solution for setting up the e-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 or 3 AC charging points (22 KW each) and a DC fast charger (25 KW) were installed in the customer area. A further AC charging point (22 KW) is available for service within the workshop. All charging points have been integrated into a site-related, 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

Charging infrastructure, monitoring and solar power perfectly integrated 

The five locations were fully equipped with the charging infrastructure by coneva and all charging points were connected to the cross-location, central monitoring system. Data from building services engineering and in-house electricity production are also integrated there. 

This is the basis for further optimized operation. The integrated dynamic load management shows first positive results: It ensures that the power actually used by the house connection is constantly measured and evaluated and that the free charging power is distributed to the charging infrastructure. The allocation and distribution of the performance limits is always carried out under consideration of the maximum house connection performance, the use of the charging points, as well as a predefined priority switching. This way, investment costs and current electricity costs could be reduced right from the start.
