The Smart Charging Gateway automatically groups all connected charge points into one cluster with the possibility to assign a max. charge current for the cluster. With the multilevel load management feature, it is possible to group multiple charge points into individual sub-clusters or charging islands with different max. charging currents. The feature therefore allows to exactly map the max. current limits of the supply cable topology. Further, it is possible to connect an individual power meter to each sub-cluster to dynamically adjust the max. charge currents per sub-cluster.
