The chargeBIG charging solution for single-phase „AC Destination Charging“ with charging power between 2.3 and 7.2kW consists of a central and intelligent control unit – the charging cabinet – and permanently fixed cables with plugs instead of charging poles or wallboxes at the parking place. Depending on the local conditions, the device at the parking slot is equipped either with a charging pillar or a wall bracket with a fixed charging cable. Instead of installing expensive components at each parking place, the necessary components (e.g. charge controller, energy measurement, fuses, etc.) are placed in the central charging cabinet. A single charging cabinet can control up to 36 charging points with single-phase charging power. Higher charging power with 22kW can be integrated in the system. 

Centralization offers considerable cost advantages not only in production but also in maintenance. The central arrangement of the electronics significantly reduces the maintenance effort. Centralization also offers advantages over conventional solutions in the field of communication and IT security. In addition, chargeBIG has a clear advantage in terms of electrical safety. Only when the vehicle is connected and safely grounded, a charging point is supplied with power. In cases of vandalism or accidents there is no danger because the charging point is without power.
