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.

A method for active noise reduction in an electric or hybrid vehicle includes (i) detecting noise in an area surrounding the vehicle by at least one sound recording apparatus which is attached to the vehicle, and (ii) generating anti-phase sound by at least one sound output apparatus, which is attached to the vehicle, depending on a signal recorded by the sound recording apparatus. The generated anti-phase sound is generated with respect to a portion of the noise in the area surrounding the vehicle and is output into the area surrounding the vehicle. Also described is a corresponding electric or hybrid vehicle which is designed to perform active noise reduction with respect to its ambient noise.
