Latest Patents

Kent Wikstrom holds a patent for a "Method for detecting a ground fault, a control unit and an energy storage system." This patent describes a method for detecting a ground fault in an energy storage system that includes at least one string of multiple energy storage modules. The string connects between a first direct current (DC) pole and a second DC pole, which are linked to an AC side through respective converters. The method involves determining a first co-phasal harmonic component based on phase-to-ground voltage measured at the AC side and a second co-phasal harmonic component based on pole-to-ground voltage measured at the DC side. A ground fault is identified if the first co-phasal harmonic component increases or the second co-phasal harmonic component decreases. This innovation is crucial for improving the reliability of energy storage systems.
