  • Centralized and scalable charging infrastructure solution, ideal for day parkers and fleet operators

  • Grid-friendly and intelligent distribution of the available total power through dynamic and phase-individual load management

  • Optimal use of the existing grid connection and thus considerable time and cost savings during the installation of charging infrastructure

  • Minimal maintenance costs due to central arrangement of the components

  • Charging of twice as many electric vehicles compared to existing charging solutions

The ideal solution chargeBIG

chargeBIG is the ideal solution for parking areas where many electric vehicles are parked for longer time periods, such as at airports or trade fairs, in company car parks, on the sites of fleet operators, in city logistics hubs, in the housing sector or in large public car parks.

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.
