Document Type and Number:
WIPO Patent Application WO/2020/192314
Kind Code:
A1
Abstract:
Disclosed are an energy storage system electric arc detection and protection method and a related device, used for improving the accuracy of electric arc detection in an energy storage system, enabling prompt arc extinguishing measures, and decreasing the probability of hidden safety hazards. The method comprises: a control device obtains an electrical signal of an electrical connection point in an energy storage system; the control device determines a frequency domain amplitude according to frequency domain characteristics of the electrical signal; when the frequency domain amplitude is greater than a preset amplitude, the control device controls the energy storage system to perform arc extinguishing and protection operations on the electrical connection point.
