The chargeBIG charging infrastructure offers single-phase charging capacities between 2 – 7 kW (max. 32 A). Intelligently controlled and single-phase outputs are ideal for daytime parking or charging at night, parallel charging of many vehicles and utilization of the existing grid connection. The phase-individual and dynamic load management controls the charging processes, depending on how many other vehicles are charging and how much maximum power is available at the location. Individual charging points can be integrated into the chargeBIG system with three-phase charging power, i.e. 11 or 22kW (max. 32A three-phase) for visitor parking spaces, for example.

The chargeBIG charging infrastructure pays off from a requirement of at least 18 charging points at one location. The solution is also particularly suitable for larger application areas with up to 100 or more charging points.

The charging cabinet, i.e. the central control unit and the sub-distribution board for the charging points, can control up to 36 single-phase charging points or 30 single-phase and two three-phase charging points when fully equipped.

The chargeBIG solution is not only suitable for indoor use, but also for outdoor use. The charging cabinets for outdoor use can be optionally equipped with a sealing package and/or air conditioning.

The chargeBIG charging points have a permanently installed type 2 charging cable.

The integration of three-phase AC charging points into the chargeBIG system is possible for visitor parking lots, for example. However, the large number of charging points is implemented with intelligent, single-phase charging power. The integration of DC charging solutions into the chargeBIG system is possible on request.

The chargeBIG solution offers the choice between static or intelligent and dynamic load management with a “first come – first serve” strategy. The integration of other power generators or loads in the building is easily possible. Grid-optimized load management based on the grid frequency and load management based on sports market prices are currently still under development.

The chargeBIG solution can be connected directly to the building via the low-voltage main distribution board or the house connection. The load management can balance all other consumers and use the electric vehicles as a shelf load, while other consumers such as the kitchen or the test bench are prioritized. The load management system either reacts autonomously within seconds to defined dynamic or static maximum load specifications or it is integrated into the building management system and follows the specifications from the building management system.

If the local load management fails, for example due to the emergency specification in the building management system or a network failure, all charging processes switch to emergency charging, which can be parameterized to 6 or 10A per charging point.
