Abstract: A voltage filtering method for a detecting point in a circuit, a switch state detection method and a related apparatus, which may be used in the technical field of new energy, the voltage filtering method for a detecting point in a circuit including: continuously collecting multiple voltage data of a detecting point in a target circuit; respectively obtaining a plurality of voltage filtering values corresponding to the detecting point by preforming filter modes based on the multiple voltage data; comparing the plurality of voltage filtering values, and if the corresponding comparison result meets a preset condition, determining a voltage target value of the detecting point based on the plurality of voltage filtering values. The present disclosure effectively verifies the validity of the voltage filtering for the detecting point in the circuit, and then ensures the reliability of the voltage filtering for the detecting point, thereby effectively improving the accuracy and reliability of subsequent control or detection according to the filtered voltage.
