The invention discloses a risk assessment method and system for fast charging pile equipment. The method comprises the steps that the equipment health condition and the equipment degradation degree are calculated according to the assessed fast charging pile equipment and the relation between the fault probability and the health index; the risk of equipment failure is calculated; based on the equipment health condition and the fault risk, a data monetization algorithm is adopted to carry out trend assessment, two kinds of fault rate statistics are used, and fault risk calculation is combined, so that the overall trend assessment data source is more comprehensive; monetization is carried out on the data, so that a unified reference is provided for data comparison and processing.
