chargeCLUSTER

Integrated and centralized sub-distribution

The key to electrification is a centralized approach.
With chargeBIG charging infrastructure, the chargeCLUSTER sub-distribution is already integrated as standard, ensuring smooth communication between the charging points.
In the case of conventional wallbox charging solutions, the sub-distribution has to be configured separately and is a significant cost item.

The chargeBIG charging systems all have dynamic load management and the option of billing in compliance with calibration law. This makes the charging solutions the ideal solution for all target groups, whether for businesses or the public and private sectors.

Advantages of a centralized approach

Wartungsfreundlich

Der Wartungsaufwand wird durch die zentrale Anordnung der Elektronik deutlich reduziert.

Ressourcenschonend

Kommunikation und Stromverteilung befinden sich in einem System. Somit werden auf lange externe Verkabelungen, wie Ethernet o.ä. verzichtet.

Sicherheit

In Fällen von Vandalismus oder Unfällen ist aufgrund des stromlosen Ladepunktes keine Gefährdung gegeben.

Intelligente Unterverteilung

Im Bereich der Kommunikation und der IT-Sicherheit bietet ein zentralisierter Ansatz Vorteile gegenüber konventionellen Lösungen.

How dynamic load management works

Sicherheit

Das dynamische Lastmanagement reagiert auf den Stromverbrauch der Kantine und reguliert die Ladeleistung der E-Fahrzeuge, um die Spitzenlast nicht zu überschreiten. So ist eine sichere Nutzung Ihres Anschlusses gewährleistet ohne Spannungs- und Thermikgrenzen zu überschreiten.

Kosten-Effizienz

Durch das dynamische Lastmanagement werden Kosten für eine Netzerweiterung reduziert und teure Spitzenlasten vermieden.

Skalierbarkeit

Erst durch ein dynamisches Lastmanagement ist es überhaupt möglich eine hohe Anzahl an Ladepunkten an einem Standort zur Verfügung zu stellen.  

So funktioniert das dynamische chargeBIG Lastmanagement

smallBOX Ladesystem bei Bau und Heim in Stuttgart

Eichrechtskonformität

Die eichrechtskonforme Abrechnung erfolgt im chargeBIG Backend (dies gilt nicht im Falle der Nutzung eines Dritt-Anbieter Backends). Dabei dient das Smartphone des Nutzers als eichrechtskonforme Anzeige.
Das Backend erstellt Rechnungsbelege für die Nutzer, übermittelt die Zahlungsdaten an den Zahlungsdienstleister, und generiert das Reporting über die Ladedaten. Zur Prüfung der eichrechtskonformen Abrechnung kann die Transparenzsoftware des S.A.F.E. e.V. genutzt werden.

Nacheichung im Feld

Die Nacheichung des smallBOX Ladesystems ist nach acht Jahren auch im Feld problemlos möglich. Dank des zentralisierten Ansatzes sind alle wartungsnotwendigen Komponenten in den chargeCLUSTER Einheiten zusammengefasst. Somit ist eine Nacheichung ohne Arbeiten an den individuellen Ladepunkten möglich.  

FAQs

The charging system can be used at all six charging points simultaneously.

The charging points have a maximum three-phase charging power of 22kW, but can be throttled down to 11kW.

The chargeBIG6 solution includes central load management, whereby the system prevents overloading of the house connection. Due to the central design of the system, investment costs are reduced. Likewise, maintenance in the operational context can be carried out with reduced effort.

The system provides a single supply line for each charging point. This can be laid directly from the meter box of the respective user, for example.

Alternatively, the system can be connected with the expansion package chargeBIG6-AP01 with one or two common supply lines for all charging points.

The variant with six supply lines is ideal for apartment buildings. The six charging points can each be connected via the apartment meter. However, this requires modern building technology. The workshop/commercial package includes appropriate bridges/phase bars so that all six charging points can be connected via one supply line. Load management works with both variants.

Charging points that are not required can simply be left free. Further expansion of the charging points is possible at any time. However, the supply line for the first charging point must always be connected.

The chargeBIG6 charging station includes all the necessary technology for a charging process, as well as a type 2 charging cable with corresponding wall bracket. For the installation, only cables with fastening material and an appropriate pre-fuse are required (e.g. C40 for 32A charging current). The pre-fuse is installed in the sub-distribution. NYM-J or NYY-J 7x6mm² is recommended for the cabling. Depending on the location, conduits or cable trays may be required.

Yes, the charging system includes a central load management with total current limitation in the standard scope of delivery. The current limit or the total current can be parameterized to 36A, 63A or 125A.

These represent the permissible total current of all six charging points. If six electric vehicles are charging at the same time and the house connection is scarce, then they will each only charge with 6A. 6x6A = 36A total current. The default setting is 63A.

The system includes intelligent temperature derating. In addition, a potential-free normally closed contact can be used to switch off the system. Thus, fire alarm systems or emergency stop systems can be implemented easily.

In the user manual, you will find the troubleshooting procedure in the Error Management chapter. If you cannot find a solution to your problem in the user manual, contact support at support@chargeBIG.com.

A fuse protects the corresponding circuit against overload and short circuit. After a fuse has tripped, the circuit must be checked for faults. The fuse should not be switched on again until the circuit is fault-free.

The system should be regularly checked and maintained in accordance with the locally applicable regulations. For companies, we recommend a semi-annual inspection of the personal protection equipment by an electrotechnically instructed person and annual maintenance of the system by a competent installer.
