Electric arc detection method, system and device of energy storage system, and computer equipment

The invention relates to an arc detection method, system and device of an energy storage system, computer equipment and a computer readable storage medium. The method comprises the steps that a sampling current signal of a to-be-detected point in the energy storage system is acquired, and the to-be-detected point is a node between a battery cluster of the energy storage system and an energy storage converter; according to multiple arc characteristics of the arc signal, an arc detection model is determined, the arc detection model is used for representing a corresponding relation between the current signal and an arc detection result, and the multiple arc characteristics at least comprise two of a time domain characteristic, a frequency domain characteristic and a wavelet characteristic of the arc signal; and performing sliding window processing on the sampling current signal, and inputting the sampling current signal subjected to the sliding window processing into the arc detection model to obtain an arc dete
