Zusammenfassung:	Embodiments of this application disclose an arc detection method for performing protection in an energy storage system, and a related apparatus, to improve accuracy of arc detection in an energy storage system, promptly take an arc extinguishing measure, and reduce a probability of causing a safety hazard. The method in the embodiments of this application includes: A control apparatus obtains an electrical signal at an electrical connection point in an energy storage system. The control apparatus determines a frequency domain amplitude based on a frequency domain characteristic of the electrical signal. When the frequency domain amplitude is greater than a preset amplitude, the control apparatus controls the energy storage system to perform an arc extinguishing and protection operation on the electrical connection point.
