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

Easy to maintain

The central arrangement of the electronics significantly reduces maintenance work.

Conserving resources

Communication and power distribution are in one system. This eliminates the need for long external cabling, such as Ethernet or similar.

Safety and Security

In cases of vandalism or accidents, there is no danger due to the currentless charging point.

Intelligent sub-distribution

In the area of communication and IT security, a centralized approach offers advantages over conventional solutions.

How dynamic load management works

Safety

Dynamic load management reacts to the canteen's power consumption and regulates the charging power of the electric vehicles so as not to exceed the peak load. This ensures safe use of your connection without exceeding voltage and thermal limits.

Cost efficiency

Dynamic load management reduces the cost of expanding the grid and avoids expensive peak loads.

Scalability

Only dynamic load management makes it possible to provide a large number of charging points at a location.

Billing in compliance with calibration law

Billing in compliance with calibration law takes place in the chargeBIG backend (this does not apply if a third-party provider backend is used). The user's smartphone serves as a display in compliance with calibration law.
The backend creates invoice receipts for the users, transmits the payment data to the payment service provider and generates the reporting on the charging data. The S.A.F.E. e.V. transparency software can be used to check that billing complies with calibration law.

Recalibration in the field

The smallBOX charging system can be easily recalibrated in the field after eight years. Thanks to the centralized approach, all components requiring maintenance are combined in the chargeCLUSTER units. This means that recalibration is possible without having to work on the individual charging points.

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.
