Method and device for estimating power metering error of fast charging station, computer device and readable storage medium
By splitting, completing, and filtering charging order data, a reference charging station cluster is constructed, and the power metering error is derived. This solves the problems of low power metering efficiency and poor applicability in existing technologies, and achieves more efficient and accurate power metering error estimation.

Abstract
This application relates to a method, apparatus, computer equipment, computer-readable storage medium, and computer program product for estimating the energy metering error of fast charging stations. The method includes: acquiring charging order data from multiple fast charging stations; segmenting the charging order data into data segments and supplementing the information in the resulting segments; removing interfering data segments and performing stability screening on the data segments based on the corresponding battery pack energy density; constructing a reference charging station cluster based on the remaining data segments, and constructing a metering performance comparison chain based on the reference charging station cluster; and deriving the energy metering error of each fast charging station in the metering performance comparison chain based on the constant characteristic of battery pack energy density. This method can improve the detection efficiency of energy metering.
