A load management system for managing loads in a power distribution grid. The load management system includes a control unit and at least two current transformers, which are each connected to the control unit by a signal cable. A first current transformer of the at least two current transformers is arranged in the power distribution grid such that the first current transformer is suitable for measuring a current level that is dominant in a grid connecting line of the power distribution grid, which grid connecting line is connected to a power supply company. A second current transformer of the at least two current transformers is arranged in the power distribution grid such that the second current transformer is suitable for measuring the current level that is dominant in a power line of the power distribution grid, which power line feeds at least one charging station of the power distribution grid.

Load management system and method for managing loads in a power distribution grid

A battery system having a battery having at least one first battery element, at least one second battery element and a center tap between the at least one first and the at least one second battery element, a power changeover switch having a plurality of switching elements for changing over between the at least one first battery element and the at least one second battery element, and at least one pair of output terminals that is electrically connected to the battery, wherein the center tap has a first capacitive store arranged on it that has a store voltage that appears over an appropriate period in accordance with a first and/or second battery element voltage provided by the first and/or second battery element, wherein during the period in which the store voltage appears, a store current decreases from a maximum value to a value of zero.
